Introduction
\layout Standard

This manual covers the customization features present in LyX.
 In it, we discuss issues like keyboard shortcuts, screen previewing options,
 printer options, sending commands to LyX via the LyX Server, internationalizati
on, installing new LaTeX classes and LyX layouts, etc.
 We can't possibly hope to touch on everything you can change---our developers
 add new features faster than we can document them---but we will explain
 the most common customizations and hopefully point you in the right direction
 for some of the more obscure ones.

LyX configuration files
\layout Standard


\begin_inset LatexCommand \label{chap:config}

This chapter aims to help you to find your way through the LyX configuration
 files.
 Before continuing to read this chapter, you should find out where your
 LyX library directory is by using

 This directory is the place where LyX places its system-wide configuration
 files, and we will simply name it

\family default 
 in the remainder of this document.
 
\layout Section

What's in 
\family typewriter 
LyXDir
\family default 
?
\layout Standard


\family typewriter 
LyXDir
\family default 
 and its sub-directories contain a number of files and that can be used
 to customise LyX's behaviour.
 You can change many of these files from within LyX itself through the 
\family sans 
\bar under

 Most customization that you might want to do to LyX is possible through
 this dialog.
 However, many other inner aspects of LyX can be customized by modifying
 the files in 
\family typewriter 
LyXDir
\family default 
.
 They fall in different categories, described in the following subsections.

Even if you are using LyX as an unprivileged user, you might want to change
 LyX configuration for your own use.
 The

\family default 
, which means that every file in 
\family typewriter 
UserDir
\family default 
 is a replacement for the corresponding file in 
\family typewriter

\family default 
.
 Any configuration file described in the above sections can be placed either
 in the system-wide directory, in which case it will affect all users, or
 in your local directory for your own use.
\layout Standard

To make things clearer, let's provide a few examples:

\family sans 
\bar under

\bar default

 (see section\SpecialChar ~

\begin_inset LatexCommand \ref{sec:autodetected}

\end_inset 

 to have a list of the 
\family typewriter

 This means that any additional text class file that you might have added
 in

\family sans 
\bar under

\layout Section

Running LyX with multiple configurations
\layout Standard

The configuration freedom of the local configuration directory may not suffice
 if you want to have more than one configuration at your disposal.
 For example, you may want to be use different key bindings or printer settings
 at different times.
 You can achieve this by having several such directories.
 You then specify which directory to use at run-time.
\layout Standard

Invoking LyX with the command line switch 
\family typewriter 
-userdir 
\family default 
\emph on 
<some directory>
\emph default 
 instructs the program to read the configuration from that directory, and
 not from the default directory (you can determine the default directory
 by running LyX without this switch as described above).
 If this directory does not exist, LyX offers to create it for you, just
 like it does for the default directory on the first time you run the program.
 You can modify the configuration options in this additional 
\family typewriter 
Userdir
\family default 
 exactly as you would for the default directory.
 These directories are completely independent (but read on).
 Note that setting the environment variable 
\family typewriter 
LYX_USERDIR_13x
\family default 
 to some value has exactly the same effect
\family typewriter 
.
\layout Standard

Having several configurations also requires more maintenance: if you want
 to add a new layout to 
\family typewriter 
Userdir/layouts
\family default 
 which you want available from all your configurations, you must add it
 to each directory separately.
 You can avoid this with the following trick: after LyX creates the additional
 directory, most of the subdirectories (see above) are empty.
 If you want the new configuration to mirror an existing one, replace the
 empty subdirectory with a symbolic link to the matching subdirectory in
 the existing configuration.
 Take care with the 
\family typewriter 
\series medium 
doc/
\family default 
\series default 
 subirectory, however, since it contains a file written by the configuration
 script (also accessible through 
\family sans 
\bar under 
T
\bar default 
ools\SpecialChar \menuseparator

\bar under 
R
\bar default 
econfigure 
\begin_inset LatexCommand \ref{sec:autodetected}

\family default 
 which is configuration-specific.

\layout Section

On-screen fonts
\layout Standard

The font used to display your documents on the LyX screen is very important,
 since you'll be reading all your documents with this font.
 Therefore it is important that the font is as readable and good-looking
 as possible.
 The LyX team tried to provide the best possible default font for you, but
 since practically all X11 systems are different, it's likely that the default
 fonts will be sub-optimal on your system.
 Fortunately, you can do something about this.
 Before we explain how to do this, you should learn a bit more about fonts
 so that you are better prepared for choosing your fonts, because it is
 a trade-off that is specific to your preferences and the capabilities of
 your system.
\layout Standard

Notice that this section only deals with the fonts on the 
\emph on 
screen
\emph default 
 inside the LyX window.
 The fonts that appear on the 
\emph on 
paper
\emph default 
 
\emph on 
output
\emph default 
 are independent from these fonts, and are determined by the document class.
 Read the 
\emph on 
User's Guide
\emph default 
 to learn how to change the font of the printed version of your document.
\layout Standard

Basically, screen fonts come in two different kinds: scalable outline fonts
 and non-scalable bitmap fonts.
 This distinction seems a bit arbitrary, since non-scalable fonts are actually
 scalable in most modern font renderers.
 The difference lies in the 
\emph on 
quality
\emph default 
 of the scaling, and the 
\emph on 
speed
\emph default 
 of display.
 The most important decision is thus whether you should use non-scalable
 bitmap fonts or scalable outline fonts.
\layout Standard

The scalable fonts are built from 
\emph on 
outlines
\emph default 
 of the single glyphs (i.e.
 characters) in the font.
 This means that each glyph is defined using mathematical curves that are
 well suited for scaling to any requested size.
 This mathematical definition is interpreted by the font renderer and turned
 into a small picture composed of pixels according to which size and glyph,
 the programmer requests.
 This means that scalable fonts will look pretty good in all sizes.
 Well, almost all sizes.
 Since scalable fonts are defined in an abstract way, it can be hard to
 provide a good rendering at small sizes, where each pixel has to be very
 carefully computed to provide a good image.
 Technically it is possible to do this from the mathematical definition,
 but in order to keep the rendering reasonably fast, tradeoffs have to be
 made, and the result is that scalable fonts can be difficult to read at
 small sizes.
\layout Standard

Bitmap fonts on the other hand, are defined by bitmap graphics from the
 start, so they will look good at all the sizes they are meant for.
 However, they don't scale well, because in order to scale a glyph, each
 pixel is enlarged into several pixels.
 It is the same effect that happens if you try to enlarge a picture in 
\family typewriter 
xv
\family default 
 or any other picture manipulation program.
 In order to relieve this effect, bitmap fonts are typically provided in
 several fixed sizes typically from around 8 pixels high up to 34 pixels
 or so high in steps according to what is believed to be useful.
 The advantage of bitmap fonts is that no complicated computations are necessary
 to display each glyph, so bitmap fonts are thus faster displayed than scalable
 fonts.
 The disadvantage is that sizes that don't exists as fixed versions have
 to be scaled by doubling pixels, and thus look bad.
\layout Standard

The net result of all this, is that bitmap fonts are generally best for
 the small sizes, where they are available, while scalable fonts are generally
 best for large sizes.
 The logical conclusion would thus be to use bitmap fonts for the small
 sizes, and scalable fonts for the large sizes.
 Unfortunately, this is not a good idea, since bitmap fonts and scalable
 fonts are not designed to be used together, so the overall look of such
 a scheme would be bad.
 The best you can do is thus to try both schemes and decide for yourself
 what suits you.
\layout Standard

By default, LyX uses non-scalable bitmap fonts (when using the XForms frontend).
 For serif fonts, 
\emph on 
times
\emph default 
 is used, for sans serif fonts, 
\emph on 
helvetica
\emph default 
 is used, while 
\emph on 
courier
\emph default 
 is used as the monospaced/typewriter font.
\layout Standard

In the following, we will describe what to do if the text does not look
 good in LyX.
 We'll start with the most important parameters: DPI and font zoom.
\layout Subsection

DPI setting and Font Zoom
\layout Standard

LyX automatically tries to scale the fonts to look as close as the paper
 output size as possible, except for the so-called font zoom factor.
\layout Standard

In order for this to work on all systems, it relies on the screen DPI (dots
 per inch) setting to be correct.
 The DPI setting for your system is autodetected by LyX using the information
 the X server can provide.
 You can check what LyX autodetects the DPI setting to, by running LyX as
 
\family typewriter 
lyx -dbg 2
\family default 
.
\layout Standard

On many systems, X is not set up correctly, so you should check that it
 is correct by hand.
 Run 
\begin_inset Quotes eld
\end_inset 


\family typewriter 
xdpyinfo | more
\family default 

\begin_inset Quotes erd
\end_inset 

 and write down what the DPI is for the resolution you use (this will be
 close to the value LyX detects).
 It is the number mentioned as 
\begin_inset Quotes eld
\end_inset 

resolution
\begin_inset Quotes erd
\end_inset 

.
 Also write down the number of pixels you have in the width (the first number
 under 
\begin_inset Quotes eld
\end_inset 

dimensions
\begin_inset Quotes erd
\end_inset 

).
\layout Standard

Then get the good old ruler out of the closet, and measure the width of
 the visible screen-image on your monitor.
 Convert this measurement to inches if you used a centimeter ruler by dividing
 by 2.54.
 Now you can determine the correct DPI setting for your screen by dividing
 the number of pixels in the width by the width of the screen-image on the
 monitor.
 If this number is more than, say, 5 DPI from the detected value, you should
 either fix the X setup, or at least tell LyX that the DPI is different
 than the detected value.
\layout Standard

If you can't fix the X setup (which of course is best since other programs
 than LyX will benefit from this as well), you can tell LyX the correct
 DPI using the 
\family sans 
Preferences
\family default 
 dialog.
\layout Standard

If the text is too small or too big for your taste, you should fiddle with
 the font zoom setting.
 This setting is used to scale the point size of the text.
 If your DPI setting is correct, and the font zoom setting is set to 100,
 this means that LyX will try to display the text exactly the same size
 as it will appear on the paper-output.
 If you set the zoom factor to 200, the text will try to be 2 times as big
 as on paper.
 Of course, this will only happen if LyX can find a font that has the appropriat
e size, which you can't count on.
 Since LyX is a WYSIWYM system anyways, this limitation isn't much of an
 issue.
\layout Standard

The default font zoom setting is 150, since a monitor is typically wider
 than a piece of paper, but you should try to fiddle with it through the
 
\family sans 
Font\SpecialChar ~

\bar under 
Z
\bar default 
oom
\family default 
 setting in the 
\family sans 
Preferences
\family default 
 dialog to find a size that you like.
 When you've found a setting that seems to work nicely for you (tip: use
 the 
\family sans 
\bar under 
A
\bar default 
pply
\family default 
 button to keep the dialog open while you experiment), you can make this
 setting the default by using the 
\family sans 
\bar under 
S
\bar default 
ave
\family default 
 button.
\layout Standard

While it is often possible to find a suitable size for the text on the screen,
 this doesn't necessarily mean that the fonts are the best ones available
 on your system.
 In order to help you get the most out of your system, you can use the font
 definition commands to fine-tune the look of the text in greater detail
 than merely size.
\layout Subsection

Font definition commands
\layout Standard

As mentioned, LyX uses non-scalable bitmap fonts by default with the XForms
 frontend.
 For serif fonts, 
\emph on 
times
\emph default 
 is used, for sans serif fonts, 
\emph on 
helvetica
\emph default 
 is used, while 
\emph on 
courier
\emph default 
 is used as the monospaced/typewriter font.
\layout Standard

You can change all of these from within the 
\family sans 
Preferences
\family default 
 dialog.
 The number of fonts that are available on different systems vary, but the
 program 
\family typewriter 
xfontsel
\family default 
 should be available everywhere.
 Use that program to find candidate fonts.
 When you've found a font that you like, try to insert the first two elements
 of the name (called

.
 LyX will then reformat your document using the new font, and if you like
 the font, you should 
\family sans 
\bar under 
S
\bar default 
ave
\family default 
 it.
 One place to start for a new font is to see if the scalable font 
\begin_inset Quotes eld
\end_inset 

utopia
\begin_inset Quotes erd
\end_inset 

 is available.
 Tip: You can see whether a font is a bitmap font or a scalable font by
 checking the 
\begin_inset Quotes eld
\end_inset 

resx
\begin_inset Quotes erd
\end_inset 

 or 
\begin_inset Quotes eld
\end_inset 

resy
\begin_inset Quotes erd
\end_inset 

 fields in 
\family typewriter 
xfontsel
\family default 
.
 If the value 0 is available, the font is scalable.
 If the value 0 isn't available, the font is a bitmap font.
\layout Standard

Before you go about scrapping a bitmap font because the larger sizes look
 
\begin_inset Quotes eld
\end_inset 

blocky
\begin_inset Quotes erd
\end_inset 

, you should toggle the 
\begin_inset Quotes eld
\end_inset 

Use scalable fonts
\begin_inset Quotes erd
\end_inset 

 button.
 This is only useful if you use bitmap fonts, because only these don't scale
 well.
 If you define this flag, LyX will only use the fixed font sizes that are
 available, and this guarantees that all bitmap fonts look well.
 (You can see which individual font sizes are available with the 
\family typewriter 
xlsfonts
\family default 
 command.
 Try 
\family typewriter 
man xlsfonts
\family default 
.) However, the prize is that the difference between the size of the fonts
 on screen and the size of fonts on paper will be larger because LyX will
 have to be satisfied with the closest available size, and not try to scale
 a size to fit.
 Also, you can risk that some logically different sizes, such as 
\family sans 
Large
\family default 
 and 
\family sans 
Larger
\family default 
, will be mapped to the same screen font, making it hard for you to see
 the difference on screen.
 We've decided not to use scalable fonts by default because of these artifacts,
 but since LyX is a WYSIWYM system, many people like to use the flag anyways,
 well-knowing that the font size on the screen can't be trusted.
 But remember that this flag only makes a difference when you use bitmap
 fonts.
 Scalable fonts won't be affected for reasons you should understand by now.
\layout Standard

One final note regarding this flag: you should know that there is nothing
 wrong with using bitmap and scalable fonts at the same time for different
 purposes.
 For instance, it's common to use the scalable 
\begin_inset Quotes eld
\end_inset 

Utopia
\begin_inset Quotes erd
\end_inset 

 for the serif text together with a bitmap version of 
\begin_inset Quotes eld
\end_inset 

Helvetica
\begin_inset Quotes erd
\end_inset 

.
 And you can safely select the 
\begin_inset Quotes eld
\end_inset 

Use scalable fonts
\begin_inset Quotes erd
\end_inset 

 button without worries: It will only apply to the Helvetica font.
\layout Standard

Sometimes the artifacts introduced by use of the flag can be relieved by
 using the fine-detail screen font sizes which defines which point sizes
 the different logical font sizes correspond to.
 Run LyX as 
\family typewriter 
lyx -dbg 513
\family default 
 to see exactly what concrete fonts the logical sizes map to, and try adjusting
 the corresponding entries in the 
\family sans 
Preferences
\family default 
 dialog until you've managed to hit the nail and get the fonts you want.
 This can be hard to do, because LyX uses the DPI setting and the font zoom
 settings to calculate which exact screen font size to ask the X server
 for, thus obfuscating the mapping.
 If you can't make it by trial-and-error, you can make the process more
 transparent if you set both the DPI setting and font zoom settings to 100---eve
n when this is known to be wrong.
 This will of course make your scalable fonts look weird, so use with care.
\layout Subsection

Font encoding
\layout Standard

By default, LyX will use fonts meant to write Western European text, including
 all kinds of English.
 This is defined through the so-called 
\emph on 
font
\emph default 
 
\emph on 
encoding
\emph default 
.
 If you want to use LyX to write for instance Eastern European text, Cyrillic
 or any other language not covered by the ISO-8859-1 font encoding, you
 can define a different one with the encoding setting.
 This requires you to have special fonts installed.
 You can use 
\family typewriter 
xfontsel
\family default 
 to see whether this is the case: check the 
\begin_inset Quotes eld
\end_inset 

rgstry
\begin_inset Quotes erd
\end_inset 

 and 
\begin_inset Quotes eld
\end_inset 

encdng
\begin_inset Quotes erd
\end_inset 

 fields for ISO-8859-X values different from ISO-8859-1, and search for
 one that contains the national characters of your language.
 If you find any, enter this encoding in the dialog.
 If not, go searching the Web for appropriate fonts.
 For the Qt frontend, it's recommended you use an iso646 font set.
\layout Standard

When you've set LyX up to use a different font encoding, you should also
 consider changing the font used by dialog windows in LyX.
 For instance, the 
\family sans 
Table\SpecialChar ~
of\SpecialChar ~
Contents
\family default 
 dialog will not be understandable unless you tell LyX to use a different
 font for this.
 By default the menu font is set to 
\family typewriter 
-*-helvetica-medium-r
\family default 
, but often Helvetica is not available in the font encoding you need, so
 the dialog allows this to be changed.
\layout Standard

As you can see, there are quite a few options that can be used to fine tune
 the look of your fonts.
 This should not scare you from fiddling with the settings, because after
 all, you will hopefully be using LyX for many hours in the future.
 And contrary to real WYSIWYG word processors where you are tied to using
 fonts that have to look good both on paper and on screen, LyX gives you
 the possibility of using fonts that are designed to look good on the screen
 while using a different set of fonts to look good on paper.
\layout Section

Bindings
\begin_inset LatexCommand \label{sec:bindings}

\end_inset 


\layout Standard

Bindings are used to, well, bind a function to a key.
 Several prepackaged binding files are available: a CUA set of bindings
 (familiar as the typical set of PC and CDE set of keyboard shortcuts),
 an Emacs set of bindings, for those of us who follow the One True Way and
 refuse to lower our standards,
\begin_inset Foot
collapsed true

\layout Standard

I'm kidding here, of course!
\end_inset 

 as well as specialty bindings (broadway and hollywood) and other languages
 (French, German, etc.).
\layout Standard

If, however, you'd like to customise the keybindings to your own exacting
 tastes, then copy the best-fit file in 
\family typewriter 
LyXDir/bind/
\family default 
 to your own 
\family typewriter 
UserDir/bind/
\family default 
 and modify that.
 Don't forget to load this new file into LyX using the 
\family sans 
Preferences
\family default 
 dialog.
 (For the moment you'll have to restart LyX for these changes to take effect.)
\layout Standard

LyX supports internationalization of the user interface (see Chapter\SpecialChar ~

\begin_inset LatexCommand \ref{chap:i18n}

\end_inset 

).
 If your 
\emph on 
locale
\emph default 
 is set, with the environment variable 
\family typewriter 
$LANG
\family default 
, LyX will try to use bindfiles by prepending 
\family typewriter 
$LANG_
\family default 
 to their name.
 For example, you can put a translated copy of some standard bind file in
 your personal 
\family typewriter 
bind/
\family default 
 directory, and LyX will use it automatically.
\layout Standard

The syntax of the 
\family typewriter 
.bind
\family default 
 files is straightforward:
\layout Standard


\family typewriter 

\backslash 
bind <key combination> <lyx-function>
\layout Standard

Both key combination and lyx-function (including any arguments) must be
 enclosed in "double quotes".
 All the LyX functions are listed in the 
\emph on 
Reference Guide
\emph default 
.
\layout Section

User Interface
\begin_inset LatexCommand \label{sec:ui}

\end_inset 


\layout Standard

The appearance of both the menu and toolbar may both be changed using the
 
\family sans 
Preferences
\family default 
 dialog.
 Simply change the 
\family typewriter 
.ui
\family default 
 file in 
\family typewriter 
LyXDir/ui/
\family default 
.
 For the moment, only one file exists, 
\family typewriter 
default.ui
\family default 
, but feel free to experiment.
 Just copy the file to the 
\family typewriter 
UserDir/ui/
\family default 
 directory and play! Note that, for the moment, you'll have to restart LyX
 for these changes to take effect.
\layout Standard

The syntax of the 
\family typewriter 
.ui
\family default 
 files is straightforward: have a look at 
\family typewriter 
default.ui.
 The Menubar
\family default 
, 
\family typewriter 
Menu
\family default 
 and 
\family typewriter 
Toolbar
\family default 
 entries must be ended with an explicit 
\family typewriter

\family default 
.
 They may contain 
\family typewriter 
Submenu

 One small word of warning.
 
\family typewriter 
Submenu
\family default 
s may be inserted in a 
\family typewriter 
Menubar
\family default 
 or 
\family typewriter

\family default 
, but they are defined as

\family default 
s, not as 
\family typewriter 
Submenu
\family default 
s.
\layout Section

Converters, Formats, Viewers, Editors and Copiers
\layout Standard

LyX has a powerful mechanism to convert to and from any file format using
 external programs.
 Define a pair of formats, e.g.

\family typewriter 
 LaTeX
\family default 
 and 
\family typewriter 
PDF
\family default 
.
 Now define a converter from one format to the other.
 In our example, two possible mechanisms exist.
\layout Enumerate

A direct conversion, from LaTeX to PDF using pdflatex
\layout Enumerate

A more convoluted route using intermediate formats and converters: LaTeX
 to DVI (using latex) to PostScript® (using dvips) to PDF (using ps2pdf).
\layout Standard

LyX will always choose the shortest possible route, so you must specify
 two different Format names for 
\family typewriter 
.pdf
\family default 
 files to be able to use either.
 Both are included by default in the 
\family sans 
Preferences
\family default 
 dialog.
 Have a look and then invent your own!
\layout Standard

Moreover, each Format can have a Viewer associated with it.
 For example, you might want to use 
\family typewriter 
ghostview
\family default 
 to examine PostScript® files, or 
\family typewriter 
xdvi
\family default 
 to preview the LaTeX output.
 You can alter the viewer to use (and what options to pass to it) via the
 
\family sans 
\bar under 
T
\bar default 
ools\SpecialChar \menuseparator

\bar under 
P
\bar default 
references:Conversion
\family default 
 dialog.
 For example, to change the 
\family typewriter 
dvi
\family default 
 viewer, select the 
\family typewriter 
DVI
\family default 
 format in the dialog, change the viewer to be 
\family typewriter 
kdvi
\family default 
 (or whatever), and hit 
\family sans 
\bar under 
M
\bar default 
odify
\family default 
.
\layout Standard

Editors are like viewers: Each Format can have an Editor associated to it,
 and they can be altered via the 
\family sans 
\bar under 
T
\bar default 
ools\SpecialChar \menuseparator

\bar under 
P
\bar default 
references:Conversion
\family default 
 dialog.
 LyX uses them whenever an included file
\begin_inset Foot
collapsed true

\layout Standard

This can be an included 
\family typewriter 
.tex
\family default 
 file, a verbatim included text file, external material or an included graphics
 file.
\end_inset 

 needs to be edited.
\layout Standard

Finally, each Format can have a Copier associated to it.
 Since all conversions from one Format to another take place in a temporary
 directory, it is sometimes necessary to modify a file before copying it
 to the temporary directory
\begin_inset Foot
collapsed true

\layout Standard

For example, the file may reference other files with relative filenames,
 which will become invalid in the temporary directory
\end_inset 

.
 This is done by the Copier: It copies a file to (or from) the temporary
 directory and may modify it in the process.
\layout Section

BibTeX and makeindex
\layout Standard

Both the bibliography generating command (default 
\family typewriter 
bibtex
\family default 
) and the index generating command (default 
\family typewriter 
makeindex
\family default 
 with options 
\family typewriter 
-c
\family default 
 and 
\family typewriter 
-q
\family default 
) can be changed.
 As an alternative for 
\family typewriter 
makeindex
\family default 
, 
\family typewriter 
xindy
\family default 
 can be recommended.
 
\layout Standard

The command to enter is
\layout Quote


\family typewriter 
makeindex.sh -m $$lang
\layout Standard

where the placeholder 
\family typewriter 
$$lang
\family default 
 will be replaced by the chosen document (babel) language.
 For this, you must 
\layout Standard

have installed the packages 
\family typewriter 
xindy
\family default 
 and 
\family typewriter 
make-rules
\family default 
 (
\family typewriter 
xindy-make-rules
\family default 
).
 Type 
\family typewriter 
makeindex.sh
\family default 
 at a shell prompt for a help page.
\layout Section

ASCII export options
\layout Standard
\added_space_top bigskip \noindent 
There are a couple of commands that can be used to 
\begin_inset Quotes eld

\end_inset 

 exported ASCII text files.
 Note that LyX automatically detects and uses the best settings for your
 system at installation time, but you can modify them if you disagree with
 its interpretation.
\layout Description


\family typewriter 
\series medium 
ASCII\SpecialChar ~
roff
\family default 
 
\series default 
This option defines the command used to produce better ASCII tables with
 the 
\family typewriter 
groff/troff/nroff
\family default 
 UNIX-commands (refer to their manpages for more information about them).
 Setting this as empty tells LyX to use the internal (inferior) formatter.
\layout Description


\family typewriter 
\series medium 
ASCII\SpecialChar ~
line\SpecialChar ~
length
\family default 
 
\series default 
With this command you can set the default line length of the ASCII output
 file.
 Setting it to 0 means endless lines.
\layout Section

Printer
\layout Standard

There are a bunch of configuration options that are used for interaction
 with the external print command from LyX.
 Normally the defaults are fine: if, however, your print command takes different
 option names, you can modify them here.
\layout Subsection

Changing Colors
\layout Standard

You can change the colors used by LyX on-screen using the new 
\family sans 
Preferences
\family default 
 dialog.
 Alternatively, if you're feeling particularly perverse you could use the
 
\family typewriter 
set-color
\family default 
 bindable function (see the 
\emph on 
Reference Guide
\emph default 
).
 Input would have the format:
\layout Standard


\family typewriter 
set-color LyXName X11Color

The rest
\layout Standard

There are many other configuration options that can be used to customize
 LyX behavior.
 We still need to document them here, but again, most should be fairly obvious.
 Please ask on the mailing lists if you need some more information; it may
 even prompt us to expand this section.

Internationalizing LyX
\begin_inset LatexCommand \label{chap:i18n}

\end_inset 


\layout Standard

LyX supports using a translated interface.
 Last time we checked, LyX provided text in 14 languages together with the
 default English text.
 The language of choice is called your 
\emph on 
locale
\emph default 
.
 (For further reading on locale settings, see also the documentation for
 locale that comes with your operating system.
 For Linux, the manual page for locale(5) could be a good place to start).
\layout Standard

Notice that these translations will work, but do contain a few flaws.
 In particular, all dialogs have been designed with the English text in
 mind, which means that some of the translated text will be too large to
 fit within the space allocated.
 This is only a display problem and will not cause any harm.
 Also, you will find that some of the translations do not define short-cut
 keys for everything.
 Sometimes, there are simply not enough free letters to do it.
 Other times, the translator just hasn't got around to doing it yet.
 We'll try to fix these shortcomings in future versions of LyX.
\layout Section

Selecting an alternative language for the user interface
\layout Standard

This feature is disabled by default, meaning that the text will be English.
 To enable an alternative language, you have to set an appropriate environment
 variable.
 Use 
\family typewriter 
"setenv LANG xx"
\family default 
 
\family roman 
for csh class shells
\family default 
 or 
\family typewriter 
"export LANG=xx"
\family default 
 
\family roman 
for sh class shells
\family default 
.
 Substitute the 
\family typewriter 
xx
\family default 
 with the two letter code for the language you want.
 For instance, 
\family typewriter 
no
\family default 
 is Norwegian.
\layout Standard

Normally, you'll want to put the appropriate line in 
\family typewriter 
~/.Xsession
\family default 
 or 
\family typewriter 
~/.xinitrc
\family default 
 so that the translation is on by default.
 Remember that if LyX is configured and compiled with 
\begin_inset Quotes eld
\end_inset 


\family typewriter 
--disable-nls
\family default 

\begin_inset Quotes erd
\end_inset 

, this will not work.
\layout Section

Translating LyX
\layout Subsection

Translating the graphical user interface (text messages).
\layout Standard

LyX uses the GNU 
\family typewriter 
gettext
\family default 
 library to handle the internationalization of the interface.
 To have LyX speak your favorite language in all menus and dialogs, you
 need a 
\family typewriter 
po
\family default 
-file for that language.
 When this is available, you'll have to generate a mo-file from it and install
 the 
\family typewriter 
mo
\family default 
-file.
 The process of doing all of this is explained in the documentation for
 GNU 
\family typewriter 
gettext
\family default 
, but in short, this is what you do (
\series bold 
xx 
\series default 
denotes the language code):
\layout Standard

 (if 
\family typewriter 
lyx.pot
\family default 
 doesn't exist, it can be remade with
\family typewriter 
 make lyx.pot
\family default 
 in that directory, or you can use an existing po-file for some other language
 as a template).
\layout Itemize

Edit 
\family typewriter 
xx.po
\begin_inset Foot

\layout Standard

We recommend that you use Emacs to do this, since the 
\family typewriter 
gettext 
\family default 
distribution includes a nice mode that supports you in doing this.
\end_inset 


\family default 
.
 For some menu- and widget-labels, there are also shortcut keys that should
 be translated.
 Those keys are marked after a `|', and should be translated according to
 the words and phrases of the 
\series bold 
xx
\series default 
-language.
 There is a tool named 
\family typewriter 
scgen.pl
\family default 
 written in Prolog in 
\family typewriter 
LYX-SOURCE-DIR/development/tools/
\family default 
 that may be useful to help determine short-cut keys.
 Note that XForms (version 0.86 at least) can't handle anything but 7-bit
 characters as shortcut keys.
 You should also fill also out the information at the beginning of the new
 
\family typewriter 
po
\family default 
-file with your email-address, etc., so people know where to reach you with
 suggestions and entertaining flames.
\layout Itemize

Generate

Adding a new po-file to the 
\emph on 
distribution 
\emph default 
of LyX involves altering the configure scripts and more, but the way 
\family typewriter 
gettext
\family default 
 works, you don't actually need the source-code of LyX to translate it---having
 
\family typewriter 
lyx.pot
\family default 
 (or an existing 
\family typewriter 
po
\family default 
-file) and the 
\family typewriter 
gettext
\family default 
 tools suffices.
\layout Standard

If you've written a translation file for a language that LyX does not currently
 support, feel free to submit it for inclusion by sending a patch.
 In this case, we recommend that you read the 
\family typewriter 
README
\family default 
 provided in the 
\family typewriter 
LYX-SOURCE-DIR/po/
\family default 
 directory for more instructions.
\layout Subsubsection

Ambigous messages
\layout Standard

Sometimes it turns out that one english message needs to be translated into
 different messages in the target language.
 One example is the message 
\family typewriter 
To
\family default 
 which has the german translation 
\family typewriter 
\lang german
Nach
\family default 
\lang english
 or 
\family typewriter 
\lang german
Bis
\family default 
\lang english
.
 
\family typewriter 
gettext
\family default 
 does not handle such ambigous translations.
 Therefore you have to add some context information to the message: Instead
 of 
\family typewriter 
To
\family default 
 it becomes 
\family typewriter 
To[[as in 'From format x to format y']]
\family default 
 and 
\family typewriter 
To[[as in 'From page x to page y']].

\family default 
 Now the two occurences of 
\family typewriter 
To
\family default 
 are different for 
\family typewriter 
gettext
\family default 
 and can be translated correctly to 
\family typewriter 
\lang german
Nach
\family default 
\lang english
 and 
\family typewriter 
\lang german
Bis
\family default 
\lang english
, respectively.
\layout Standard

Of course the context information needs to be stripped off the original
 message when no translation is used.
 Therefore you have to put it in double square brackets at the end of the
 message (see the example above).
 The translation mechanism of LyX ensures that everything in double square
 brackets at the end of messages is removed before displaying the message.
\layout Subsection

Translating the documentation.
\layout Standard

The online documentation (in the 
\family sans 
\bar under 
H
\bar default 
elp
\family default 
-menu) can (and should!) be translated.
 If there are translated versions of the documentation available
\begin_inset Foot
collapsed true

\layout Standard

As of February 2003, almost all of the docs have been translated into German
 and French.
 The 
\emph on 
Tutorial
\emph default 
 has been translated into at least 12 other languages, with other translations
 in progress.
 The library of translated documents is growing rapidly.
\end_inset 

, and the locale is set accordingly, these will be used automagically by
 LyX.
 LyX looks for translated versions as 
\family typewriter 
LyXDir/doc/
\series bold 
xx
\series default 
_DocName.lyx
\family default 
, where 
\family typewriter 
\series bold 
xx
\family default 
\series default 
 denotes the language as set by the environmental variable 
\family typewriter 
$LANG
\family default 
.
 If there are none, the default English versions will be displayed.
 Note that the translated versions must have the same filenames (
\family typewriter 
DocName
\family default 
 above) as the original.
 If you feel up to translating the documentation (an excellent way to proof-read
 the original documentation BTW!), there are a few things you should do
 right away:
\layout Itemize

Read 
\family typewriter 
DocStyle.lyx
\family default 
, the guide to writing LyX documentation.
 Pay special attention to the translator's section.
\layout Itemize

Check out the documentation translation web page at 
\begin_inset LatexCommand \url[The LyX Developer's Web Site]{http://www.devel.lyx.org}

\end_inset 

.
 That way, you can find out which (if any) documents have already been translate
d into your language.
 You can also find out who (if anyone) is organizing the effort to translate
 the documentation into your language.
 If no one is organizing the effort, please let us know that you're interested.
\layout Standard

Once you get to actually translating, here's a few hints for you that may
 save you trouble:
\layout Itemize

Join the documentation team! There is information on how to do that in 
\family typewriter 
Intro.lyx
\family default 
 (
\family sans 
\bar under

\bar default 
elp\SpecialChar \menuseparator

\bar under 
I
\bar default 
ntroduction
\family default 
), which by the way is the first document you should translate.
\layout Itemize

Learn the typographic conventions for the language you are translating to.
 Typography is an ancient art and over the centuries, a great variety of
 conventions have developed throughout different parts of the world.
 Also study the professional terminology amongst typographers in your country.
 Inventing your own terminology will only confuse the users.
 
\emph on 
(Warning! Typography is addictive!)
\layout Itemize

Make a copy of the document.
 This will be your working copy.
 You can use this as your personal translated help-file by placing it in
 your 
\family typewriter 
~/.lyx/doc/
\family default 
-directory.
\layout Itemize

Sometimes the original document (from the LyX-team) will be updated.
 Use the ViewCVS tool available at 
\begin_inset LatexCommand \htmlurl{http://www.lyx.org/viewcvs.cgi/lyxdoc/}

\end_inset 

 to see what has been changed
\begin_inset Foot
collapsed true

\layout Standard

Alternatively, you can keep a copy of the latest version of the English
 document which you've translated.
\end_inset 

.
 That way you can easily see which parts of the translated document need
 to be updated.
\layout Itemize

If you ever find an error in the original document, fix it and notify the
 rest of the documentation team of the changes! (You didn't forget to join

where 
\family typewriter 
key

 is the string to be inserted into the document.
 To define dead keys, use:
\layout Quotation

\layout Quotation


\family typewriter 

\backslash 
kxmod
\family default 
 
\family typewriter

to make it work correctly.
 Also, you have to define as exceptions dead keys over i and j, to remove
 the dot from them before inserting an accent mark.
 I will change this when the time comes, but so far I haven't had time.
\layout Standard

Oh, and about characters: backslash is escaped, so to enter it, you'll need
 double backslash.
 Also, quotes and 
\family typewriter

 It allows you to combine the effect
\family roman 
 of 
\emph on 
accent1
\emph default 
 and 
\emph on 
accent2
\emph default 
 (in that order!) on 
\emph on 
allowed
\emph default 
 chars.
 The keystrokes for 
\emph on 
accent1
\emph default 
 and 
\emph on 
accent2
\emph default 
 must have be
\family default 
en set with a 
\family typewriter 
\shape up 

\backslash 
kmod
\family default 
\shape default 
 command at 
\family roman 
a 
\emph on 
previous
\emph default 
 point in the 
\family default

\layout Standard

Consider this example from the 
\family typewriter 
\shape up 
greek.kmap
\family default 
\shape default 
 file:
\layout LyX-Code


\backslash 
kmod ; acute aeioyvhAEIOYVH 
\backslash 
kmod : umlaut iyIY 
\backslash 
kcomb acute umlaut iyIY
\layout Standard

This allows you to press 
\family sans 
\shape up 
;:i
\family default 
\shape default 
 and get the effect of 
\family typewriter 
\shape up 

\backslash 
'{
\backslash 
"{i}}
\family default 
\shape default 
.
 
\family roman 
\shape up 
A backspace 
\family default 
\shape default 
in this case cancels the last dead key, so if you press
\family sans 
\shape up 
 ;: Backspace i 
\family default 
\shape default 
you get 
\family typewriter 
\shape up 

\backslash 
'{i}
\family default

The .cdef File
\layout Standard

After the 
\family typewriter 
\shape up 
.kmap
\family sans 
 
\family default 
\shape default 
mapping is performed, a 
\family typewriter 
\shape up 
.cde
\shape default 
f
\family default 
 file maps the strings that the symbols generate to characters in the current
 font.
 The LyX distribution currently includes at least the 
\family typewriter 
\shape up 
iso8859-1.cdef
\family default 
\shape default 
 and 
\family typewriter 
\shape up 
iso8859-2.cdef
\family default 
\shape default 
 files.
\layout Standard

In general the 
\family typewriter 
\shape up 
.cdef
\family sans 
 
\family default 
\shape default 
file is a sequence of declarations of the form
\layout LyX-Code


\family roman 
\emph on 
char_index_in_set
\emph default 
 
\emph on 
 string
\layout Standard

For example, in order to map 
\family sans 
\shape up 

\backslash 
'{e}
\family default 
\shape default 
 to the corresponding character in the iso-8859-1 set (233), the following
 declaration is used
\layout LyX-Code

233 "
\backslash 

\backslash 
'{e}"
\layout Standard

with 
\family typewriter 

\backslash 

\family default 
 and 
\family typewriter 
"
\family default 
 being escap
\family roman 
ed in 
\emph on 
string
\emph default 
.
 Note that 
\family default 
the same character can apply to more than one string.
 In the 
\family typewriter 
i
\shape up 
so-8859-7.cdef
\family sans 
 
\family default 
\shape default 
file you have
\layout LyX-Code

192 "
\backslash 

\backslash 
'{
\backslash 

\backslash 

\backslash 
"{i}}"
\newline 
192 "
\backslash 

\backslash 

\backslash 
"{
\backslash 

\backslash 
'{i}}"
\layout Standard

If LyX cannot find a mapping for the string produced by the keystroke or
 a deadkey sequence, it will check if it looks like an accented char and
 try to draw an accent over the character on screen.
\layout Subsection

Dead Keys
\layout Standard

There is a second way to add support for international characters through
 so-called dead-keys.
 A dead-key works in combination with a letter to produce an accented character.
 Here, we'll explain how to create a really simple dead-key to illustrate
 how they work.
\layout Standard

Suppose you happen to need the circumflex character, 
\begin_inset Quotes eld
\end_inset 

\i \^{}

\begin_inset Quotes erd
\end_inset 

.
 You could bind the 
\family sans 
^
\family default 
-key [a.k.a.\SpecialChar ~

\family sans 
Shift-6
\family default 
] to the LyX command 
\family typewriter 
accent-circumflex
\family default 
 in your 
\family typewriter 
lyxrc
\family default 
 file.
 Now, whenever you type the 
\family sans 
^
\family default 
-key followed by a letter, that letter will have a circumflex accent on
 it.
 For example, the sequence 
\begin_inset Quotes eld
\end_inset 


\family sans 
^e
\family default 

\begin_inset Quotes erd
\end_inset 

 produces the letter: 
\begin_inset Quotes eld
\end_inset 

ê
\begin_inset Quotes erd
\end_inset 

.
 If you tried to type 
\begin_inset Quotes eld
\end_inset 


\family sans 
^t
\family default 

\begin_inset Quotes erd
\end_inset 

, however, LyX will complain with a beep, since a 
\begin_inset Quotes eld
\end_inset 


\family sans 
t
\family default 

\begin_inset Quotes erd
\end_inset 

 never takes a circumflex accent.
 Hitting 
\family sans 
Space
\family default 
 after a dead-key produces the bare-accent.
 Please note this last point! If you bind a key to a dead-key, you'll need
 to rebind the character on that key to yet another key.
 Binding the 
\family sans 
,-key
\family default 
 to a cedilla is a bad idea, since you'll only get cedillas instead of commas.
\layout Standard

One common way to bind dead-keys is to use 
\family sans 
Meta-
\family default 
, 
\family sans 
Ctrl-
\family default 
, and 
\family sans 
Shift-
\family default 
 in combination with an accent, like 
\begin_inset Quotes eld
\end_inset 


\family sans 
~
\family default 

\begin_inset Quotes erd
\end_inset 

 or 
\begin_inset Quotes eld
\end_inset 


\family sans 
,
\family default 

\begin_inset Quotes erd
\end_inset 

 or 
\begin_inset Quotes eld
\end_inset 


\family sans 
^
\family default 

\begin_inset Quotes erd
\end_inset 

.
 Another way involves using 
\family typewriter 
xmodmap
\family default 
 and 
\family typewriter 
xkeycaps
\family default 
 [remember them from section?] to set up the special 
\family typewriter 
Mode_Switch
\family default 
 key.
 The 
\family typewriter 
Mode_Switch
\family default 
 acts in some ways just like 
\family sans 
Shift
\family default 
 and permits you to bind keys to accented characters.
 You can also turn keys into dead-keys by binding them to something like
 
\family typewriter 
usldead_cedilla
\family default 
 and then binding this symbolic key to the corresponding LyX command.
\begin_inset Foot

\layout Standard

Note from 
\noun on 
John Weiss
\noun default 
: This is exactly what I do in my 
\family typewriter 
~/.lyx/lyxrc

 I have my 
\family sans 
Scroll\SpecialChar ~

\family default

\family typewriter 
Mode_Shift
\family default 
 and a bunch of these 
\begin_inset Quotes eld
\end_inset 


\family typewriter 
usldead_*
\family default 

\begin_inset Quotes erd
\end_inset 

 symbolic keys bound such things as 
\family sans 
Scroll\SpecialChar ~
Lock-^
\family default 
 and 
\family sans 
Scroll\SpecialChar ~
Lock-~
\family default 
.
 This is how I produce my accented characters.
\end_inset 

 You can make just about anything into the 
\family typewriter 
Mode_Switch
\family default 
 key: One of the 
\family sans 
Ctrl-
\family default 
 keys, a spare function key, etc.
 As for the LyX commands that produce accents, check the entry for 
\family typewriter 
accent-acute
\family default 
 in the 
\emph on 
Reference Manual
\emph default 
.
 You'll find the complete list there.

Installing New Document Classes
\end_inset 


\layout Standard

In this chapter, we describe the procedures for creating and installing
 new LyX layout and template files, as well as offer a refresher on correctly
 installing new LaTeX document classes.
 Some definitions: a document class is a LaTeX file (usually ending in 
\family typewriter 
.cls
\family default 
 or 
\family typewriter 
.sty
\family default 
) which describes the format of a document such as an article, report, journal
 preprint, etc.
 and all the commands needed to realize that format.
 A layout file is a LyX file which corresponds to a LaTeX document class
 and which tells LyX how to 
\begin_inset Quotes eld
\end_inset 

draw
\begin_inset Quotes erd
\end_inset 

 things on the screen to make the display look something like the final
 printed page.
 More precisely, a layout file describes a 
\begin_inset Quotes eld
\end_inset 

text class
\begin_inset Quotes erd
\end_inset 

 which is the internal construct LyX uses to render the screen display.
 
\begin_inset Quotes eld
\end_inset 

Layout
\begin_inset Quotes erd
\end_inset 

 and 
\begin_inset Quotes eld
\end_inset 

text class
\begin_inset Quotes erd
\end_inset 

 can be used somewhat interchangeably, but it is better to refer to the
 file as the layout, and the thing living in LyX's memory as the text class.
 A template file is simply a LyX document which contains a set of predefined
 entries for a given document class which are generally required for that
 class.
 Templates are especially useful for things like journal manuscripts which
 are to be submitted electronically.
\layout Section

Installing a new LaTeX package
\layout Standard

Some installations may not include a LaTeX package that you would like to
 use within LyX.
 For example, you might need FoilTeX, a common (and very powerful) package
 for preparing slides or viewgraphs for overhead projectors.
 Here are the formal steps involved in getting the package up and running
 if you are using teTeX or some other web2c based distribution.
 
\layout Enumerate

Get the package from CTAN or wherever.
\begin_inset Foot
collapsed true

\layout Standard

See the 
\emph on 
Inventory of your LaTeX configuration
\emph default 
 manual for details of what CTAN is and where supported document classes
 can be found.
\end_inset 


\layout Enumerate

Read the file 
\family typewriter 
texmf.cnf
\family default 
 (this usually lives in the directory 
\family typewriter 
$TEXMF/web2c
\family default 
, though you can run 
\family typewriter 
kpsewhich texmf.cnf
\family default 
 to locate it).
 It describes how to add a local 
\family typewriter 
texmf
\family default 
 directory; follow the instructions.
 You need to insert the name of your local 
\family typewriter 
texmf
\family default 
 directory in 
\family typewriter 
texmf.cnf
\family default 
.
 Under Linux, 
\family typewriter 
/usr/local
\family default 
 is a logical place to install software that did not come with your distribution
, so you might use 
\family typewriter 
/usr/local/texmf
\family default 
.
 Usually, you will have to modify only two things:
\begin_deeper 
\layout Enumerate

Set 
\family typewriter 
TEXMFLOCAL
\family default 
 to the directory you chose; e.g.
 
\newline 

\family typewriter 
TEXMFLOCAL = /usr/local/texmf
\layout Enumerate

Make sure 
\family typewriter 
TEXMF
\family default 
 includes the 
\family typewriter 
TEXMFLOCAL
\family default 
 variable; e.g.
 
\newline 

\family typewriter 
TEXMF = {$HOMETEXMF,!!$TEXMFLOCAL,!!$TEXMFMAIN}
\end_deeper 
\layout Enumerate

Create your local 
\family typewriter 
texmf
\family default 
 directory (e.g.
 
\family typewriter 
/usr/local/texmf
\family default 
).
 You must follow the directory structure of your existing 
\family typewriter 
texmf
\family default 
 directory (for example, latex packages should go under 
\family typewriter 
/usr/local/texmf/tex/latex/
\family default 
).
\layout Enumerate

Install the package.
 For example, you would unpack the FoilTeX tarball and create 
\family typewriter 
/usr/local/texmf/tex/latex/foiltex
\family default 
.
 The 
\family typewriter 
foiltex
\family default 
 directory contains various files.
\layout Enumerate

Run: 
\family typewriter 
texhash
\family default 
.
 This should create 
\family typewriter 
/usr/local/texmf/ls-R 
\family default 
amongst others.
\layout Enumerate

From within LyX, do: 
\family sans 
\bar under 
T
\bar default 
ools\SpecialChar \menuseparator

\bar under 
R
\bar default 
econfigure
\family default 
.
 Restart LyX.
\layout Standard

Now you should see your new package---for example 
\family sans 
slides (FoilTeX)
\family default 
---under 
\family sans 
\bar under 
L
\bar default 
ayout\SpecialChar \menuseparator

\bar under 
D
\bar default 
ocument
\family default 
, field 
\family sans 
\bar under 
C
\bar default 
lass
\family default 
.
 Note that there are simpler ways of installing packages: you can add a
 link to the new package directory in the system LaTeX directory (
\family typewriter 
$TEXMF/tex/latex
\family default 
, don't forget to then run 
\family typewriter 
texconfig
\family default 
), or sometimes simply set the 
\family typewriter 
$TEXINPUTS
\family default 
 environment variable to include the new package.
 However, the formal procedure described in 
\family typewriter 
texmf.cnf
\family default 
 is guaranteed to work, so you should follow it unless circumstances absolutely
 prevent it: such as, when you don't have superuser access.
\layout Section

Layouts
\layout Standard

This section describes how to write and install your own LyX layout files
 (also known as text classes) and walks through the 
\family typewriter 
article
\family default 
 text class format as an example.
 The 
\family typewriter 
.layout
\family default 
 files describe what paragraph styles are available for a given document
 class and how LyX should display them.
 We try to provide a thorough description of the process here; however,
 there are so many different types of documents supported by LaTeX classes
 we can't hope to cover every different possibility or problem you might
 encounter.
 
\layout Standard

When you plan to write a new layout, it is extremely helpful to look at
 the example layouts distributed with LyX.
 If you use a nice LaTeX document class that might be of interest for others,
 too, and have a nice corresponding LyX layout, feel free to contribute
 the stuff to us, so we may put it into the distribution.
\layout Standard

All the tags described in this chapter are case-insensitive; this means
 that 
\family typewriter 
Style
\family default 
, 
\family typewriter 
style
\family default 
 and 
\family typewriter 
StYlE
\family default 
 are really the same command.
 The possible values are printed in brackets after the feature's name.
 The default value if a feature isn't specified inside a text class-description
 is typeset 
\family typewriter 
\emph on 
emphasized
\family default 
\emph default 
.
 If the argument has a datatype like 
\begin_inset Quotes eld
\end_inset 

string
\begin_inset Quotes erd
\end_inset 

 or 
\begin_inset Quotes eld
\end_inset 

float
\begin_inset Quotes erd
\end_inset 

, the default is shown like this: 
\family typewriter 
float=
\emph on 
default
\family default 
\emph default 
.
\layout Subsection

Supporting new document classes
\layout Standard

There are two situations you are likely to encounter when wanting to support
 a new LaTeX document class, involving LaTeX2e class (
\family typewriter 
.cls
\family default 
) and style (
\family typewriter 
.sty
\family default 
) files.
\layout Subsection

A layout for a 
\family sans 
sty
\family default 
 file
\layout Standard

If your new document class is provided as a style file that is used in conjuncti
on with an existing, supported document class, start by copying the existing
 class's layout file into your local directory.
 For the sake of example we'll assume that the style file is called 
\family sans 
myclass.sty
\family default 
 and it is meant to be used with 
\family sans 
report.cls
\family default 
 which is a standard class.
\layout LyX-Code

cp report.layout ~/.lyx/layouts/myclass.layout
\layout Standard

Then edit 
\family typewriter 
myclass.layout
\family default 
 and change the line: 
\layout LyX-Code


\backslash 
DeclareLaTeXClass{report}
\layout Standard

to read
\layout LyX-Code


\backslash 
DeclareLaTeXClass[report, myclass.sty]{report (myclass)}
\layout Standard

Then add:
\layout LyX-Code

Preamble 
\newline 
    
\backslash 
usepackage{myclass}
\newline 
EndPreamble
\layout Standard

near the top of the file.
\layout Standard

Start LyX and select 
\family sans 
\bar under 
T
\bar default 
ools\SpecialChar \menuseparator

\bar under 
R
\bar default 
econfigure
\family default 
.
 Restart LyX and try creating a new document.
 You should see "
\family sans 
report (myclass)
\family default 
" as a document class option in the 
\family sans 
\bar under 
D
\bar default 
ocument\SpecialChar \menuseparator

\bar under 
S
\bar default 
ettings
\family default 
 dialog.
 It is likely that some of the sectioning commands and such will differ
 from how the base class
\begin_inset Foot
collapsed true

\layout Standard


\family typewriter 
report
\family default 
 in this example
\end_inset 

 works, so you can fiddle around with the settings for the different sections
 if you wish.
 See below for more discussion on this.
\layout Subsection

Layout for a

\family default

\layout Standard

In this case, you will probably have to 
\begin_inset Quotes eld
\end_inset 

roll your own
\begin_inset Quotes erd
\end_inset 

 layout.
 We strongly suggest copying an existing layout file which uses a similar
 LaTeX class and modifying it if at all possible.
 At least use an existing file as a starting point so you can find out what
 items you need to worry about.
 Again, the specifics are covered below.
\layout Section

Declaring a new text class
\layout Standard

When it's finally time to get your hands dirty and create or edit your own
 layout file, the following sections describe what you're up against.
 Our advice is to go slowly, save and test often, listen to soothing music,
 and enjoy one or two of your favorite adult beverages; more if you are
 getting particularly stuck.
 It's really not that hard, except that the multitude of options can become
 overwhelming if you try to do to much in one sitting.
 Go have another adult beverage, just for good measure.
\layout Standard

Here we go!
\layout Standard

Lines in a layout file which begin with a 
\family typewriter 
#
\family default 
 are comments.
 There is one exception to this rule: all layouts should begin with lines
 like:
\layout LyX-Code


\size small 
#% Do not delete the line below; configure depends on this 
\layout LyX-Code


\size small 
#  
\backslash 
DeclareLaTeXClass{article}
\layout Standard

The second line is used when you configure LyX.
 The layout file is read by the LaTeX script 
\family typewriter 
chkconfig.ltx
\family default 
, in a special mode where 
\family typewriter 
#
\family default 
 is ignored.
 The first line is just a LaTeX comment, and the second one contains the
 declaration of the text class.
 If these lines appear in a file named 
\family typewriter 
article.layout
\family default 
, then they define a text class of name 
\family typewriter 
article
\family default 
 (the name of the layout file) which uses the LaTeX document class 
\family typewriter 
article.cls
\family default 
 (the default is to use the same name as the layout).
 The string 
\begin_inset Quotes eld
\end_inset 

article
\begin_inset Quotes erd
\end_inset 

 that appears above is used as a description of the text class in the 
\family sans 
\bar under 
D
\bar default 
ocument\SpecialChar \menuseparator

\bar under 
S
\bar default 
ettings
\family default 
 dialog.
\layout Standard

Let's assume that you wrote your own text class that uses the 
\family typewriter 
article.cls
\family default 
 documentclass, but where you changed the appearance of the section headings.
 If you put it in a file 
\family typewriter 
myarticle.layout
\family default 
, the header of this file should be:
\layout LyX-Code


\size small 
#% Do not delete the line below; configure depends on this 
\layout LyX-Code


\size small 
#  
\backslash 
DeclareLaTeXClass[article]{article (with my own headings)}
\layout Standard

This declares a text class 
\family typewriter 
myarticle
\family default 
, associated with the LaTeX document class 
\family typewriter 
article.cls
\family default 
 and described as 
\begin_inset Quotes eld
\end_inset 

article (with my own headings)
\begin_inset Quotes erd
\end_inset 

.
 If your text class depends on several packages, you can declare it as:
\layout LyX-Code


\size small 
#% Do not delete the line below; configure depends on this 
\layout LyX-Code


\size small 
#  
\backslash 
DeclareLaTeXClass[article,foo.sty]{article (with my own headings)}
\layout Standard

This indicates that your text class uses the foo.sty package.
 Finally, it is also possible to declare classes for SGML and DocBook code.
 Typical declarations will look like
\layout LyX-Code


\size small 
#% Do not delete the line below; configure depends on this 
\layout LyX-Code


\size small 
# 
\backslash 
DeclareSGMLClass{SGML (LinuxDoc)}
\layout Standard

or
\layout LyX-Code

#% Do not delete the line below; configure depends on this 
\layout LyX-Code

# 
\backslash 
DeclareDocBookClass[article]{SGML (DocBook article)}
\layout Standard

Note that these declarations can also be given an optional parameter declaring
 the name of the document class (but not a list).
\layout Standard

When the text class has been modified to your taste, all you have to do
 is to copy it either in 
\family typewriter 
$LyXDir/layouts/
\family default 
 or in 
\family typewriter 
$UserDir/layouts
\family default 
 and run 
\family sans 
\bar under 
T
\bar default 
ools\SpecialChar \menuseparator

\bar under 
R
\bar default 
econfigure
\family default 
.
 Exit LyX and restart it; then your new text class should be available along
 with the others.
\layout Subsection

These are the general parameters which describe the form of the entire document:

\series default 
 [
\family typewriter 
\emph on 
Static
\emph default 
, Manual, Dynamic, First_Dynamic, Right_Address_Box
\family default 
] 
\newline 
The kind of margin that the layout has on the left side.
 
\family typewriter 
Static
\family default 
 just means a fixed margin.
 
\family typewriter 
Manual
\family default 
 means that the left margin depends on the string entered in the

\bar default 
aragraph\SpecialChar ~

 dialog.
 This is used to typeset nice lists without tabulators.
 
\family typewriter 
Dynamic
\family default 
 means that the margin depends on the size of the label.
 This is used for automatic enumerated headlines.
 It is obvious that the headline 
\begin_inset Quotes eld
\end_inset 

5.4.3.2.1 Very long headline
\begin_inset Quotes erd
\end_inset 

 must have a wider left margin (as wide as 
\begin_inset Quotes eld
\end_inset 

5.4.3.2.1
\begin_inset Quotes erd
\end_inset 

 plus the space) than 
\begin_inset Quotes eld
\end_inset 

3.2 Very long headline
\begin_inset Quotes erd
\end_inset 

, even if other word processors are not able to do this.
 
\family typewriter 
First_Dynamic
\family default 
 is similar, but only the very first row of the paragraph is dynamic, while
 the others are static; this is used, for example, for descriptions.
 
\family typewriter 
Right_Address_Box
\family default 
 means the margin is chosen in a way that the longest row of this paragraph
 fits to the right margin.
 This is used to typeset an address on the right edge of the page.
\layout Description

\series medium 
NextNoIndent
\family default 
\series default 
 [
\family typewriter 
1, 
\emph on 
0
\family default 
\emph default 
] Whether the following Paragraph is allowed to indent its very first row.
 
\family typewriter 
1
\family default 
 means that it is not allowed to do so, 
\family typewriter 
0
\family default 
 means it could do so if it wants to.
\layout Description


\family typewriter 
\series medium 
ParIndent
\family default 
\series default 
 [
\family typewriter 
string=""
\family default 
] The indent of the very first line of a paragraph.
 The argument is passed as a string.
 For example 
\family typewriter 
"MM"
\family default 
 means that the paragraph is indented with the width of 
\family typewriter 
"MM"
\family default 
 in 
\family typewriter 
the
\family default 
 normal font.
 You can get a negative width by prefixing the string with 
\family typewriter 
"-"
\family default 
.
 This way was chosen so that the look is the same with each used screen
 font.
 The 
\family typewriter 
Parindent
\family default 
 will be fixed for a certain layout.
 The exception is Standard layout, since the indentation of a Standard layout
 paragraph can be prohibited with 
\family typewriter 
NextNoIndent
\family default 
.
 Also, Standard layout paragraphs inside environments use the 
\family typewriter 
Parindent
\family default 
 of the environment, not their native one.
 For example, Standard paragraphs inside an enumeration are not indented.
\layout Description


\family typewriter 
\series medium 
Parskip
\family default 
\series default 
 [
\family typewriter 
float=0
\family default 
] LyX allows to choose either 
\begin_inset Quotes eld
\end_inset 

indent
\begin_inset Quotes erd
\end_inset 

 or 
\begin_inset Quotes eld
\end_inset 

skip
\begin_inset Quotes erd
\end_inset 

 to typeset a document.
 When 
\begin_inset Quotes eld
\end_inset 

indent
\begin_inset Quotes erd
\end_inset 

 is chosen, this value is completely ignored.
 When 
\begin_inset Quotes eld
\end_inset 

skip
\begin_inset Quotes erd
\end_inset 

 is chosen, the parindent of a LaTeXtype 
\begin_inset Quotes eld
\end_inset 

Paragraph
\begin_inset Quotes erd
\end_inset 

 layout is ignored and all paragraphs are additionally separated by this
 parskip argument.
 The vertical space is calculated with 
\family typewriter 
value*DefaultHeight()
\family default 
 where 
\family typewriter 
DefaultHeight()
\family default 
 is the height of a row with the normal font.
 This way, the look stays the same with different screen fonts.
\layout Description


\family typewriter 
\series medium 
TopSep
\family default 
\series default 
 [
\family typewriter 
float=0
\family default 
] The vertical space with which the very first of a chain of paragraphs
 with this layout is separated from the previous paragraph.
 If the previous paragraph has another layout, the separations are not simply
 added, but the maximum is taken.
\layout Description


\family typewriter 
\series medium 
BottomSep
\family default 
\series default 
 [
\family typewriter 
float=0
\family default 
] The same as 
\family typewriter

 for the very last paragraph.
\layout Description


\family typewriter 
\series medium 
Parsep
\family default 
\series default 
 [

\layout Description


\family typewriter 
\series medium 
Itemsep
\family default 
\series default 
 [
\family typewriter 
float=0
\family default 
] This is an extra space between the paragraphs of an environment layout.
 If you put other layouts into an environment, each is separated with the
 environment's 
\family typewriter 
Parsep
\family default 
.
 But the whole items of the environment are additionally separated with
 this 
\family typewriter 
Itemsep
\family default 
.
 
\layout Description


\family typewriter 
\series medium 
LeftMargin
\family default 
\series default 
 [

string=""
\family default 
] If you put layouts into environments, the leftmargins are not simply added,
 but added with a factor 
\begin_inset Formula $\frac{4}{depth+4}$
\end_inset 

.
 Note that this parameter is also used when the border is defined as 
\family typewriter 
Manual
\family default 
 or 
\family typewriter 
Dynamic
\family default 
.
 Then it is added to the manual or dynamic border.
 This string has the same meaning as for 
\family typewriter 
ParIndent
\family default 
.

Creating Templates
\begin_inset LatexCommand \label{sec:templates}

\end_inset 


\layout Standard

Templates are created just like usual documents.
 The only difference is that usual documents contain all possible settings,
 including the fontscheme and the papersize.
 Usually a user doesn't want a template to overwrite his defaults in these
 cases.
 For that reason, the designer of a template should remove the corresponding
 commands like 
\family typewriter 

\backslash 
fontscheme
\family default 
 or 
\family typewriter 

\backslash 
papersize
\family default 
 from the template LyX file.
 This can be done with any simple text-editor, for example 
\family typewriter 
vi
\family default 
 or 
\family typewriter 
xedit
\family default 
.
 
\layout Standard

Put the edited template files you create in 
\family typewriter 
$UserDir/templates/
\family default 
, copy the ones you use from the global template directory in 
\family typewriter 
$LyXDir/templates/
\family default 
 to the same place, and redefine the template path in the 
\family sans 
\bar under 
E
\bar default

references 
\family default 
dialog (tabs 
\family sans

).
 
\layout Standard

Note that there is a template which has a particular meaning: 
\family typewriter 
defaults.lyx
\family default 
.
 This template is loaded everytime you create a new document with 
\family sans 
\bar under 
F
\bar default 
ile
\family default 
\SpecialChar \menuseparator

\family sans 
\bar under 
N
\bar default 
ew 
\family default 
in order to provide useful defaults.
 To create this template from inside LyX, all you have to do is to open
 a document with the correct settings, and use the 
\family sans

\bar default 
e as Document Defaults
\family default 
 button.

Including External Material
\layout Section

Background
\layout Standard


\begin_inset Note
collapsed true

\layout Standard

This section is completely outdated.
\end_inset 

One often requested feature from LyX users is to be able to interface LyX
 with XFig, Dia, or other similar applications that specialize in producing
 a certain kind of diagram, figure, schematic or whatever material might
 be relevant to include in your document.
 Previously, it was only possible to include boring, static, fixed images
 in LyX documents with the graphics feature, but there are several limitations
 attached to this approach:
\layout Itemize

If you want to change the figure, you have to invoke an external program
 by hand
\layout Itemize

LyX does not notice that the referenced files change, so the on-screen display
 can fast become obsolete, and this is aggravated by the lack of a means
 of updating the display
\layout Itemize

The graphics stuff does not provide any mechanisms for coping with different
 exported formats such as DocBook, HTML or raw Ascii
\layout Standard

The external material facility attempts to solve all of these problems
\begin_inset Foot
collapsed true

\layout Standard

Even if the graphics facility can't solve all problems, it is still valuable
 because it does provide in-line preview of the graphics, and supports advanced
 geometric transformations with a comfortable user interface.
\end_inset 

.
 It does this by offering a general method to interface LyX to external
 applications.
 Instead of introducing a long list of different constructs tailored for
 each specific application, we chose to sacrifice the in-line displaying
 of the included material in order to provide a general construct to cover
 a wide range of applications.
 The result is the external material construct.
 External material presents itself in the document simply as a button, but
 don't let this fool you.
 When you click on it, a dialog will appear that allows you to chose exactly
 what material to include, and in the following sections you will learn
 that this is indeed a powerful mechanism that can solve all of the above
 problems, and more.
\layout Section

How does it work?
\layout Standard

The external material feature is based on the concept of a
\emph on 
 template
\emph default 
.
 A template is a specification of how LyX should interface with a certain
 kind of material.
 As bundled, LyX comes with predefined templates for XFig figures, Dia diagrams,
 various raster format images, gnuplot, and more.
 You can check the actual list by using the 
\family sans 
Insert\SpecialChar \menuseparator
External
\family default 
\SpecialChar ~

\family sans 
Material 
\family default 
command.
 Furthermore, it is possible to roll your own template to support a specific
 kind of material.
 Later we'll describe in more detail what is involved, and hopefully you
 will submit all the templates you create so we can include them in a later
 LyX version.
\layout Standard

Another basic idea of the external material feature is to distinguish between
 the original file that serves as a base for final material and the produced
 file that is included in your exported or printed document.
 For example, consider the case of a figure produced with XFig.
 The XFig application itself works on an original file with the 
\family typewriter 
.fig
\family default 
 extension.
 Within XFig, you create and change your figure, and when you are done,
 you save the 
\family typewriter 
fig
\family default 
-file.
 When you want to include the figure in your document, you invoke 
\family typewriter 
transfig
\family default 
 in order to create a PostScript file that can readily be included in your
 LaTeX file.
 In this case, the 
\family typewriter 
.fig
\family default 
 file is the original file, and the PostScript file is the produced file.
\layout Standard

This distinction is important in order to allow updating of the material
 while you are in the process of writing the document.
 Furthermore, it provides us with the flexibility that is needed to support
 multiple export formats.
 For instance, in the case of an Ascii resulting file, it is not exactly
 an award-winning idea to include the figure as raw PostScript.
 Instead, you'd either prefer to just include a reference to the figure,
 or try to invoke some graphics to Ascii converter to make the final result
 look similar to the real graphics.
 The external material management allows you to do this, because it is parameter
ized on the different export formats that LyX supports.
\layout Standard

Besides supporting the production of different products according to the
 exported format, it supports tight integration with editing and viewing
 applications.
 In the case of an XFig figure, you are able to invoke 
\family typewriter 
xfig
\family default 
 on the original file with a single click from within the external material
 dialog in LyX, and also preview the produced PostScript file with 
\family typewriter 
ghostview
\family default 
 with another click.
 No more fiddling around with the command line and/or file browsers to locate
 and manipulate the original or produced files.
 In this way, you are finally able to take full advantage of the many different
 applications that are relevant to use when you write your documents, and
 ultimately be more productive.
\layout Standard


\begin_inset Note

\layout Standard

This paragraph is outdated
\end_inset 

So, all in all, LyX has information about a number of different programs
 to use behind the scenes in order to realize all of this machinery.
 This information, in fact, is exactly what is contained in the templates.
 To each template, there is associated a list of command lines that are
 used to invoke applications, convert the original file to the produced
 file, and more.
 This mechanism allows the advanced user to extend the capabilities of LyX
 without fiddling with the source code.
 It requires some footwork to define all the different commands and flags,
 but luckily, the LyX team did all the hard work and specified these for
 you.
\layout Standard

But before the trees grow into the skies, we have to admit that we did take
 one tiny short-cut.
 Since you can produce many different kinds of files to go with each exported
 format, one could also expect that it would be possible to preview each
 product.
 The LyX team decided against this in order to keep the user interface simple.
 Instead of providing a button for each exported file format, we decided
 to introduce the concept of the primary file format and just have one button.
 When you press 
\family sans 
View
\family default 
\SpecialChar ~

\family sans 
result
\family default 
 in the external material dialog, you will get a view of the produced file
 in the primary file format.
 And the primary file format is specified by your document class.
 For most document classes, the primary file format is LaTeX, but for the
 DocBook document classes, the primary file format is DocBook.
 So, when you view the produced file, keep in mind that it will only be
 a preview of what the main result will be.
 If you want to see how other exported formats turn out, you have to export
 them and preview them by hand.
\layout Section

The external material dialog
\layout Standard

You insert external material from the 
\family sans 
\bar under 
I
\bar default 
nsert
\family default 
 menu.
 When you do this, a button is inserted into your document, and the external
 material dialog is shown.
 This dialog allows you to describe exactly what material should be included,
 and also how it should be included.
 Furthermore, it provides access to the external applications to either
 view, edit or produce the material that is used in the resulting file.
\layout Standard


\begin_inset Note
collapsed true

\layout Standard

This paragraph is outdated
\end_inset 

At the top of this dialog, there is a drop-down list where you can chose
 which template should be used.
 Just below the template drop-down, there's a text area with a short blurb
 about the chosen template that should help you use it.
 Most often, it will provide a short description of the template, and a
 few hints on how to parameterize the use of it.
 Further down, you'll find a filename input field along with a 
\begin_inset Quotes eld
\end_inset 

Browse
\begin_inset Quotes erd
\end_inset 

 button that allows you to chose which file should be included with the
 standard file browser.
 Thus this field specifies the original file.
 Since the produced file is automatically generated when needed, there is
 no need to give access to it in the user interface.
\layout Standard


\begin_inset Note
collapsed true

\layout Standard

This paragraph is outdated
\end_inset 

At the bottom of the dialog, you'll find a general input box called 
\family sans 
Parameters
\family default 
.
 This box is generally used to parameterize the specific template.
 The specific use should be covered in the help blurb associated with the
 template, but it typically allows you to define variations on how the produced
 file should be generated.
\layout Standard


\begin_inset Note
collapsed true

\layout Standard

This paragraph is outdated
\end_inset 

At the right side of the dialog, you'll find three buttons: 
\family sans 
Edit
\family default 
\SpecialChar ~

\family sans 
file
\family default 
, 
\family sans 
View
\family default 
\SpecialChar ~

\family sans 
result
\family default 
, and 
\family sans 
Update
\family default 
\SpecialChar ~

\family sans 
result
\family default 
.
 These in turn allow you to edit your original file with the appropriate
 editing application, view the produced file as included in the primary
 format document, and finally force an update of the resulting material
 in the primary format.
 Normally, the 
\family sans 
Update
\family default 
\SpecialChar ~

\family sans 
result
\family default 
 button will be disabled, because most templates are configured to automatically
 update the produced file when needed.
 In those cases, there is no need to force the production of a new produced
 file.
 However, some templates are configured to not be automatically producing
 the residual product, because the cost of producing the produced file might
 be so large that it would be a pain to do it all the time.
 Those types are known as 
\emph on 
manual
\emph default 
 external material.
 In those cases, you can use the button to force the production of the produced
 file exactly when you need it, and thus control the amount of work that
 is done.
 In fact, it is 
\emph on 
your
\emph default 
 responsibility to do this to keep the produced files current at all times:
 before printing, before exporting, before viewing, etc.
 At some time in the future, it might be possible that LyX will help you
 with this task.Any changes in the template, filename or parameters are actually
 applied whenever you press

\layout Section

The substitution mechanism
\layout Standard

When the external material facility invokes an external program, it is done
 on the basis of a command defined in the template configuration file.
 These commands can contain various macros that are expanded before execution.
 Execution always take place in the directory of the containing document.
\layout Standard

Also, whenever external material is to be displayed, the name will be produced
 by the substitution mechanism, and most other commands in the template
 definition support substitution as well.
\layout Standard

The available macros are the following:
\layout Description

$$FName The filename of the file specified in the external material dialog.
 This is either an absolute name, or it is relative to the LyX document.
\layout Description

$$Basename The filename without path and without the extension.
\layout Description

$$Extension The file extension (including the dot).
\layout Description

$$FPath The path part of 
\family typewriter 
$$FName
\family default 
 (absolute name or relative to the LyX document).
\layout Description

$$AbsPath The absolute file path.
\layout Description

$$RelPathMaster The file path, relative to the master LyX document.
\layout Description

$$RelPathParent The file path, relative to the LyX document.
\layout Description

$$AbsOrRelPathMaster The file path, absolute or relative to the master LyX
 document.
\layout Description

$$AbsOrRelPathParent The file path, absolute or relative to the LyX document.
\layout Description

$$Tempname A name and full path to a temporary file which will be automatically
 deleted whenever the containing document is closed, or the external material
 insertion deleted.
\layout Description

$$Contents(
\begin_inset Quotes eld
\end_inset 

filename.ext
\begin_inset Quotes erd
\end_inset 

) This macro will expand to the contents of the file with the name 
\family typewriter 
filename.ext
\family default 
.
\layout Description

$$Sysdir This macro will expand to the absolute path of the system directory.
 This is typically used to point to the various helper scripts that are
 bundled with LyX.
\layout Standard

All path macros contain a trailing directory separator, so you can construct
 e.g.
 the absolute filename with 
\family typewriter 
$$AbsPath$$Basename$$Extension
\family default 
.
\layout Standard

The macros above are substituted in all commands unless otherwise noted.
 The command 
\family typewriter 
Product
\family default 
 supports additionally the following substitutions if they are enabled by
 the 
\family typewriter 
Transform
\family default 
 and 
\family typewriter 
TransformCommand
\family default 
 commands:
\layout Description

$$ResizeFront The front part of the resize command.
\layout Description

$$ResizeBack The back part of the resize command.
\layout Description

$$RotateFront The front part of the rotation command.
\layout Description

$$RotateBack The back part of the rotation command.
\layout Standard

The value string of the 
\family typewriter 
Option
\family default 
 command supports additionally the following substitutions if they are enabled
 by the 
\family typewriter 
Transform
\family default 
 and 
\family typewriter 
TransformOption
\family default 
 commands:
\layout Description

$$Clip The clip option.
\layout Description

$$Extra The extra option.
\layout Description

$$Resize The resize option.
\layout Description

$$Rotate The rotation option.
\layout Standard

You may ask why there are so many path macros.
 There are mainly two reasons:
\layout Standard

First, relative and absolute file names should remain relative or absolute,
 respectively.
 Users may have reasons to prefer either form.
 Relative names are useful for portable documents that should work on different
 machines, for example.
 Absolute names may be required by some programs.
\layout Standard

Second, LaTeX treats relative file names differently than LyX and other
 programs in nested included files.
 For LyX, a relative file name is always relative to the document that contains
 the file name.
 For LaTeX, it is always relative to the master document.
 These two definitions are identical if you have only one document, but
 differ if you have a master document that includes part documents.
 That means that relative filenames must be transformed when presented to
 LaTeX.
 Fortunately LyX does this automatically for you if you choose the right
 macros.
\layout Standard

So which path macro should be used in new template definitions? The rule
 is not difficult:
\layout Itemize

Use 
\family typewriter 
$$AbsPath
\family default 
 if an absolute path is required.
\layout Itemize

Use 
\family typewriter 
$$AbsOrRelPathMaster
\family default 
 if the substituted string is some kind of LaTeX input.
\layout Itemize

Else use 
\family typewriter 
$$AbsOrRelPathParent
\family default 
 in order to preserve the user's choice.
\layout Standard

There are special cases where this rule does not work and e.g.\SpecialChar ~
relative names
 are needed, but normally it will work just fine.
 One example for such a case is the command 
\family typewriter 
ReferencedFile latex "$$AbsOrRelPathMaster$$Basename.pstex_t"
\family default 
 in the XFig template above: We can't use the absolute name because the
 copier for 
\family typewriter 
.pstex_t
\family default 
 files needs the relative name in order to rewrite the file content.
\layout Section

Security discussion
\layout Standard


\begin_inset Note
collapsed true

\layout Standard

This section is outdated
\end_inset 

The external material feature interfaces with a lot of external programs
 and does so automatically, so we have to consider the security implications
 of this.
 In particular, since you have the option of including your own filenames
 and/or parameter strings and those are expanded into a command, it seems
 that it would be possible to create a malicious document which executes
 arbitrary commands when a user views or prints the document.
 This is something we definately want to avoid.
\layout Standard

However, since the external program commands are specified in the template
 configuration file only, there are no security issues if LyX is properly
 configured with safe templates only.
 This is so because the external programs are invoked with the 
\family typewriter 
execvp
\family default 
-system call rather than the 
\family typewriter 
system
\family default 
 system-call, so it's not possible to execute arbitrary commands from the
 filename or parameter section via the shell.
\layout Standard

This also implies that you are restricted in what command strings you can
 use in the external material templates.
 In particular, pipes and redirection are not readily available.
 This has to be so if LyX should remain safe.
 If you want to use some of the shell features, you should write a safe
 script to do this in a controlled manner, and then invoke the script from
 the command string.
 In the 
\family typewriter 
lib/scripts
\family default 
 directory of the LyX installation, you can find a safe wrapper script 
\family typewriter 
general_command_wrapper.py
\family default 
 that supports redirection of input and output.
 That can serve as an example for how to write safe template scripts.
 For a more advanced example that uses 
\family typewriter 
fork
\family default 
 and friends, take a look at the 
\family typewriter 
pic2ascii.py
\family default 
 converter script.
\layout Standard

It is possible to design a template that interacts directly with the shell,
 but since this would allow a malicious user to execute arbitrary commands
 by writing clever filenames and/or parameters, we generally recommend that
 you only use safe scripts that work with the 
\family typewriter 
execvp
\family default 
 system call in a controlled manner.
 Of course, for use in a controlled environment, it can be tempting to just
 fall back to use ordinary shell scripts.
 If you do so, be aware that you 
\emph on 
will
\emph default 
 provide an easily exploitable security hole in your system.
 Of course it stands to reason that such unsafe templates will never be
 included in the standard LyX distribution, although we do encourage people
 to submit new templates in the open source tradition.
 But LyX as shipped from the official distribution channels will never have
 unsafe templates.
\layout Standard

Including external material provides a lot of power, and you have to be
 careful not to introduce security hazards with this power.
 A subtle error in a single line in an innocent looking script can open
 the door to huge security problems.
 So if you do not fully understand the issues, we recommend that you consult
 a knowledgable security professional or the LyX development team if you
 have any questions about whether a given template is safe or not.
 And do this before you use it in an uncontrolled environment.
\layout Chapter

The LyX Server
\layout Section

Introduction
\layout Standard

The LyX server is a method implemented in LyX that will enable other programs
 to talk to LyX, invoke LyX commands, and retrieve information about the
 LyX internal state.
 This is only intended for advanced users, but they should find it useful.
\layout Section

Starting the LyX Server
\layout Standard

The LyX server works through the use of a pair of named pipes.
 These are usually located in your home directory and have the names 
\begin_inset Quotes eld
\end_inset 


\family typewriter 
.lyxpipe.in
\family default 

\begin_inset Quotes erd
\end_inset 

 and 
\begin_inset Quotes eld
\end_inset 


\family typewriter 
.lyxpipe.out
\family default 

\begin_inset Quotes erd
\end_inset 

.
 External programs write into 
\family typewriter 
.lyxpipe.in
\family default 
 and read back data from 
\family typewriter 
.lyxpipe.out
\family default 
.
 The stem of the pipe names can be defined in the 
\family sans 
\bar under 
T
\bar default 
ools\SpecialChar \menuseparator

\bar under 
P
\bar default 
references
\family default 
 dialog, for example 
\family typewriter 
"/home/myhome/.lyxpipe"
\family default 
.
\layout Standard

LyX will add the '
\family typewriter 
.in
\family default 
' and '
\family typewriter 
.out
\family default 
' to create the pipes.
 The above setting also has the effect of activating the LyX server.
 If one of the pipes already exists, LyX will assume that another LyX process
 is already running and will not start the server.
 To have several LyX processes with servers at the same time, you have to
 change the configuration between the start of the programs.
\layout Standard

If you are developing a client program, you might find it useful to enable
 debugging information from the LyX server.
 Do this by starting LyX as 
\family typewriter 
lyx -dbg lyxserver.
\layout Standard

Warning: if LyX crashes, it may not manage to remove the pipes; in this
 case you must remove them manually.
 If LyX starts and the pipes exist already, it will not start any server.
\layout Standard

Other than this, there are a few points to consider:
\layout Itemize

Both server and clients must run on UNIX or OS/2 machines.
 Communications between LyX on UNIX and clients on OS/2 or vice versa is
 not possible right now.
\layout Itemize

On OS/2, only one client can connect to LyXServer at a time.
\layout Itemize

On OS/2, clients must open inpipe with 
\family typewriter 
O_WRONLY
\family default 
 mode.
\layout Standard

You can find a complete example client written in C in the source distribution
 as 
\family typewriter 
development/server_monitor.c
\family default 
.
\layout Section

Normal communication
\layout Standard

To issue a LyX call, the client writes a line of ASCII text into the input
 pipe.
 This line has the following format:
\layout Quote

LYXCMD:
\emph on 
clientname
\emph default 
:
\emph on 
function
\emph default 
:
\emph on 
argument
\layout Standard

Here 
\emph on 
clientname
\emph default 
 is a name that the client can choose arbitrarily.
 Its only use is that LyX will echo it if it sends an answer - so a client
 can dispatch results from different requesters.
\layout Standard


\emph on 
function
\emph default 
 is the function you want LyX to perform.
 It is the same as the commands you'd use in the minibuffer.
\layout Standard


\emph on 
argument
\emph default 
 is an optional argument which is meaningful only to some functions (for
 instance 
\begin_inset Quotes eld
\end_inset 

self-insert
\begin_inset Quotes erd
\end_inset 

 which will insert the argument as text at the cursor position.)
\layout Standard

The answer from LyX will arrive in the output pipe and be of the form
\layout Quote

INFO:
\emph on 
clientname
\emph default 
:
\emph on 
function
\emph default 
:
\emph on 
data
\layout Standard

where 
\emph on 
clientname
\emph default 
 and 
\emph on 
function
\emph default 
 are just echoed from the command request, while 
\emph on 
data
\emph default 
 is more or less useful information filled according to how the command
 execution worked out.
 Some commands will return information about the internal state of LyX,
 such as 
\begin_inset Quotes eld
\end_inset 

font-state
\begin_inset Quotes erd
\end_inset 

, while other will return an empty data-response.
 This means that the command execution went fine.
\layout Standard

In case of errors, the response from LyX will have this form
\layout Quote

ERROR:
\emph on 
clientname
\emph default 
:
\emph on 
function
\emph default 
:
\emph on 
error message
\layout Standard

where the 
\emph on 
error message
\emph default 
 should contain an explanation of why the command failed.
\layout Standard

Examples:
\layout LyX-Code

echo "LYXCMD:test:beginning-of-buffer:" >~/.lyxpipe.in
\layout LyX-Code

echo "LYXCMD:test:get-xy:" >~/.lyxpipe.in
\newline 
read a <~/.lyxpipe.out
\newline 
echo $a
\layout Section

Notification
\layout Standard

LyX can notify clients of events going on asynchronously.
 Currently it will only do this if the user binds a key sequence with the
 function 
\begin_inset Quotes eld
\end_inset 

notify
\begin_inset Quotes erd
\end_inset 

.
 The format of the string LyX sends is as follows:
\layout Quote


\family typewriter 
NOTIFY:
\family default 
\emph on 
key-sequence
\layout Standard

where 
\emph on 
key-sequence
\emph default 
 is the printed representation of the key sequence that was actually typed
 by the user.
\layout Standard

This mechanism can be used to extend LyX's command set and implement macros:
 bind some key sequence to 
\begin_inset Quotes eld
\end_inset 

notify
\begin_inset Quotes erd
\end_inset 

, start a client that listens on the out pipe, dispatches the command according
 to the sequence and starts a function that may use LyX calls and LyX requests
 to issue a command or a series of commands to LyX.
\layout Section

The simple LyX Server Protocol
\layout Standard

LyX implements a simple protocol that can be used for session management.
 All messages are of the form
\layout Quote

LYXSRV:
\emph on 
clientname
\emph default 
:
\emph on 
protocol message
\layout Standard

where 
\emph on 
protocol message
\emph default 
 can be 
\begin_inset Quotes eld
\end_inset 

hello
\begin_inset Quotes erd
\end_inset 

 or 
\begin_inset Quotes eld
\end_inset 

bye
\begin_inset Quotes erd
\end_inset 

.
 If 
\begin_inset Quotes eld
\end_inset 

hello
\begin_inset Quotes erd
\end_inset 

 is received from a client, LyX will report back to inform the client that
 it's listening to it's messages, while 
\begin_inset Quotes eld
\end_inset 

bye
\begin_inset Quotes erd
\end_inset 

 sent from LyX will inform clients that LyX is closing.
\layout Chapter
\start_of_appendix 
Bindings
\layout Standard

This appendix is a huge cross-reference to all the English language keybindings.
 Originally, we simply wanted to list all of the key bindings followed by
 the function it's bound to.
 That way, a user can look up a key to find out what it does.
 We then decided, what the hey, why not include the default toolbar and
 menu bindings, too.
 Please note this section is likely to be very out of date.
\layout Standard

The form is really self-explanatory, but here are a few tips: all entries
 are arranged roughly alphabetically for a given modifier (
\family sans 
C-a
\family default 
, 
\family sans 
C-b
\family default 
, etc.).
 For the general keyboard layout, simpler prefixes precede the more complex
 (
\family sans 
C-s
\family default 
 before 
\family sans 
C-S-c
\family default 
).
 All entries were gleaned from the default user interface and binding files
 located in the directories 
\family typewriter 
\SpecialChar \ldots{}
/share/lyx/ui
\family default 
 and 
\family typewriter 
\SpecialChar \ldots{}
/share/lyx/bind
\family default 
; they should be treated as the final word on the bindings.
\layout Standard

As a final note, be aware that some window managers (such as FVWM) take
 control of some of the function keys or motion keys.
 
\family sans 
C-right
\family default 
 is listed here as generating 
\family typewriter 
word-forward
\family default 
, but FVWM grabs it and uses it to change virtual desktops instead.
 Very annoying unless you instruct your window manager to stop intercepting
 such sequences.

\layout Standard

These are LyX keyboard definitions for mathematics, similar to those of
 Scientific Word.
\layout Standard

The bindings file and the present documentation were prepared by Serge Winitzki
 with assistance from Jean-Marc Lasgouttes.
 Version 1.3, for LyX 1.2.x and 1.3.x.
\layout Standard

These definitions make it a lot easier to type equations without using the
 mouse, especially for people familiar with Scientific Word.
 The standard LyX bindings such as 
\family typewriter 
M-m
\family default 
 or 
\family typewriter 
M-o
\family default 
 are unmodified.
\layout Standard

Tip: to find the "LyX bind name" for a key, look at the status bar after
 typing some non-existent key combination.
 E.g.
 to find how "Ctrl-&" is referenced, press Ctrl-S and then Ctrl-&: the status
 bar shows "C-s S-C-ampersand." (This does not work in LyX 1.3.0!)

The bar bracket: on some keyboards (e.g.\SpecialChar ~
some British ones), the bar character
 is bound to an 
\family typewriter 
Alt
\family default 
-something and on some wayward Unices to "brokenbar".
 So we define all of these keys as well.

Here are some Sciword-inspired mnemonics for frequently used math symbols.
 Many symbols start with a 
\family typewriter 
C-s
\family default 
 sequence.
 Therefore 
\family typewriter 
C-s
\family default 
 cannot be itself bound to anything.

 in math mode.
 This is frequently unnecessary: in most cases the normal apostrophe works
 just fine, e.g.
 
\begin_inset Formula $x'+2x=0$
\end_inset 

, but in some cases this would generate a double superscript error in LaTeX.
 For example: 
\begin_inset Formula $x^{\prime2}$
\end_inset 

 (
\begin_inset Formula $x$

 prime squared) must be entered with the prime character.
