\begin_layout Chapter
Introduction
\end_layout

\begin_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.

\begin_layout Chapter
LyX configuration files
\end_layout

\begin_layout Standard
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 and user directories are by using

LyX
\end_layout

.
 The library directory is the place where LyX places its system-wide configurati
on files; the user directory is where you can place your modified versions.
 We will call the former 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LyXDir
\end_layout

\end_inset

 and the latter 
\begin_inset Flex MenuItem

\begin_layout Standard
\begin_inset Flex Code

 and its sub-directories contain a number of files and that can be used
 to customize LyX's behavior.
 You can change many of these files from within LyX itself through the 
\begin_inset Flex MenuItem

\begin_layout Plain Layout
Tools\SpecialChar \menuseparator

 dialog.
 Most customization that you will want to do in LyX is possible through
 this dialog.
 However, many other inner aspects of LyX can be customized by modifying
 the files in 
\begin_inset Flex Code

 These files fall in different categories, described in the following subsection

 They contain various default values that are guessed by inspection.
 In general, it is not a good idea to modify them, since they might be overwritt

Running LyX with multiple configurations
\end_layout

\begin_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.

Invoking LyX with the command line switch 
\begin_inset Flex Code

\begin_layout Plain Layout
-userdir
\end_layout

\end_inset

 
\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 the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
-userdir
\end_layout

\end_inset

 switch.) If the specified 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 user directory
 exactly as you would for the default directory.
 These directories are completely independent (but read on).
 Note that setting the environment variable

Having several configurations also requires more maintenance: if you want
 to add a new layout to 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
NewUserDir/layouts
\end_layout

\end_inset

 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 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
doc/
\end_layout

\end_inset

 subdirectory, however, since it contains a file written by the configuration
 script (also accessible through 
\begin_inset Flex MenuItem

 button to define your new format.
 The 
\begin_inset Flex MenuItem

\end_inset

 is used to identify the format internally.
 You will also need to enter a file extension.
 These are all required.
 The optional 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout

\end_layout

\end_inset

 field is used to provide a keyboard shortcut on the menus.
 (For example, pressing

\begin_layout Section
Copiers
\end_layout

\begin_layout Standard
Since all conversions from one format to another take place in LyX's temporary
 directory, it is sometimes necessary to modify a file before copying it
 to the temporary directory in order that the conversion may be performed.
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
For example, the file may refer to other files—images, for example—using
 relative file names, and these may become invalid when the file is copied
 to the temporary directory.
\end_layout

\end_inset

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

\begin_layout Standard
The definitions of the copiers may use four variables:
\end_layout

The latter should be the filename as it would be used in a LaTeX's 
\series bold

 It is relevant only when exporting files suitable for such inclusion.
\end_layout

\begin_layout Standard
Copiers can be used to do almost anything with output files.
 For example, suppose you want generated pdf files to be copied to a special
 directory, 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
/home/you/pdf/
\end_layout

\end_inset

.
 Then you could write a shell script such as this one:
\end_layout

\begin_layout Standard
\begin_inset listings
inline false
status open

\begin_layout Plain Layout

#!/bin/bash
\end_layout

\begin_layout Plain Layout

FROMFILE=$1
\end_layout

\begin_layout Plain Layout

TOFILE=`basename $2`
\end_layout

\begin_layout Plain Layout

cp $FROMFILE /home/you/pdf/$TOFILE
\end_layout

\end_inset

Save it in your local LyX directory—say, 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
/home/you/.lyx/scripts/pdfcopier.sh
\end_layout

\end_inset

—and make it executable, if you need to do so on your platform.
 Then, in the

\end_inset

 into the 
\begin_inset Flex MenuItem

 field.
 
\end_layout

\begin_layout Standard
Copiers are used by LyX in various of its own conversions.
 For example, if appropriate programs are found, LyX will automatically

 When these formats are exported, the copier sees that not just the main
 HTML file but various associated files (style files, images, etc.) are also
 copied.
 All these files are written to a subdirectory of the directory in which
 the original LyX file was found.

None of these last three are presently used in any of the converters that

\end_layout

\begin_layout Standard
You do not have to define converters for all formats between which you want
 to convert.
 For example, you will note that there is no `LyX to PostScript' converter,
 but LyX will export PostScript.
 It does so by first creating a LaTeX file (no converter needs to be defined
 for this) which is then converted to DVI using the `LaTeX to DVI' converter,
 and finally converting the resulting DVI file to PostScript.
 LyX finds such `chains' of converters automatically, and it will always
 choose the shortest possible chain.
 You can, though, still define multiple conversion methods between file
 formats.
 For example, the standard LyX configuration provides three ways to convert
 LaTeX to PDF: Directly, using 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
pdflatex
\end_layout

\end_inset

; via (DVI and) PostScript, using 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
ps2pdf
\end_layout

\end_inset

; or via DVI, using 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
dvipdfm
\end_layout

\end_inset

.
 To define such alternate chains, you must define multiple target `file
 formats', as described in section 
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:Formats"

\end_inset

.
 For example, in the standard configuration, the formats named 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
pdf
\end_layout

\end_inset

, 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
pdf2
\end_layout

\end_inset

, and 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout

\end_inset

 are defined, all of which share the extension 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
.pdf
\end_layout

\end_inset

, and which correspond to the conversion methods just mentioned.

 For Linux, the manual page for

 could be a good place to start).
\end_layout

\begin_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 shortcut
 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.

\end_layout

\end_inset

 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 language.
 You should also fill also out the information at the beginning of the new

\end_layout

\begin_layout Subsubsection
Ambiguous messages
\end_layout

\begin_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 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
To
\end_layout

\end_inset

 which has the German translation 
\lang german
Nach
\lang english
 or 
\lang german
Bis
\lang english
, depending upon exactly what the English 
\begin_inset Quotes eld
\end_inset

to
\begin_inset Quotes erd
\end_inset

 means.
 GNU 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
gettext
\end_layout

\end_inset

 does not handle such ambiguous translations.
 Therefore you have to add some context information to the message: Instead
 of 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
To
\end_layout

\end_inset

 it becomes 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
To[[as in 'From format x to format y']]
\end_layout

\end_inset

 and 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
To[[as in 'From page x to page y']].
\end_layout

\end_inset

 Now the two occurrences of 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
To
\end_layout

\end_inset

 are different for 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
gettext
\end_layout

\end_inset

 and can be translated correctly to 
\lang german
Nach
\lang english
 and 
\lang german
Bis
\lang english
, respectively.
\end_layout

\begin_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.
\end_layout

\begin_layout Subsection
Translating the documentation.
\end_layout

\begin_layout Standard
The online documentation (in the 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Help
\end_layout

\end_inset

-menu) can (and should!) be translated.
 If there are translated versions of the documentation available
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
As of March 2008, at least some of the documents have been translated into
 fourteen languages, with the Tutorial available in a few more.
\end_layout

\end_inset

 and the locale is set accordingly, these will be used automagically by
 LyX.
 LyX looks for translated versions as 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LyXDir/doc/xx/DocName.lyx
\end_layout

\end_inset

, where 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
xx
\end_layout

\end_inset

 is the code for the language currently in use.
 If there are no translated documents, the default English versions will
 be displayed.
 Note that the translated versions must have the same filenames (
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
DocName
\end_layout

\end_inset

 above) as the original.
 If you feel up to translating the documentation (an excellent way to proof-read
 the original documentation by the way!), there are a few things you should
 do right away:
\end_layout

\begin_layout Itemize
Check out the documentation translation web page at 
\begin_inset CommandInset href
LatexCommand href
name "http://www.lyx.org/Translation"
target "http://www.lyx.org/Translation"

\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.
\end_layout

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

\begin_layout Itemize
Join the documentation team! There is information on how to do that in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Intro.lyx
\end_layout

\end_inset

 (
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Help\SpecialChar \menuseparator
Introduction
\end_layout

\end_inset

), which by the way is the first document you should translate.
\end_layout

\begin_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!)
\end_layout

\begin_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 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
UserDir/doc/xx/
\end_layout

\end_inset

 directory.
\end_layout

\begin_layout Itemize
Sometimes the original document (from the LyX-team) will be updated.
 Use the source viewer at 
\begin_inset CommandInset href
LatexCommand href
name "http://www.lyx.org/trac/timeline"
target "http://www.lyx.org/trac/timeline"

\end_inset

 to see what has been changed.
 That way you can easily see which parts of the translated document need
 to be updated.
\end_layout

\begin_layout Standard
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
 the documentation team, did you?)

\end_layout

\begin_layout Subsection
Dead Keys
\end_layout

\begin_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.
\end_layout

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

 ̂
\begin_inset Quotes erd
\end_inset

.
 You could bind the 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
^
\end_layout

\end_inset

-key [a.k.a.
\begin_inset space ~
\end_inset


\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Shift-6
\end_layout

\end_inset

] to the LyX command 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
accent-circumflex
\end_layout

\end_inset

 in your 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
lyxrc
\end_layout

\end_inset

 file.
 Now, whenever you type the 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
^
\end_layout

\end_inset

-key followed by a letter, that letter will have a circumflex accent on
 it.
 For example, the sequence 
\begin_inset Quotes eld
\end_inset


\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
^e
\end_layout

\end_inset


\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


\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
^t
\end_layout

\end_inset


\begin_inset Quotes erd
\end_inset

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


\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
t
\end_layout

\end_inset


\begin_inset Quotes erd
\end_inset

 never takes a circumflex accent.
 Hitting 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Space
\end_layout

\end_inset

 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 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
,-key
\end_layout

\end_inset

 to a cedilla is a bad idea, since you'll only get cedillas instead of commas.
\end_layout

\begin_layout Standard
One common way to bind dead-keys is to use 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Meta-
\end_layout

\end_inset

, 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Ctrl-
\end_layout

\end_inset

, and 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Shift-
\end_layout

\end_inset

 in combination with an accent, like 
\begin_inset Quotes eld
\end_inset


\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
~
\end_layout

\end_inset


\begin_inset Quotes erd
\end_inset

 or 
\begin_inset Quotes eld
\end_inset


\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
,
\end_layout

\end_inset


\begin_inset Quotes erd
\end_inset

 or 
\begin_inset Quotes eld
\end_inset


\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
^
\end_layout

\end_inset


\begin_inset Quotes erd
\end_inset

.
 Another way involves using 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
xmodmap
\end_layout

\end_inset

 and 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
xkeycaps
\end_layout

\end_inset

 to set up the special 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Mode_Switch
\end_layout

\end_inset

 key.
 The 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Mode_Switch
\end_layout

\end_inset

 acts in some ways just like 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Shift
\end_layout

\end_inset

 and permits you to bind keys to accented characters.
 You can also turn keys into dead-keys by binding them to something like
 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
usldead_cedilla
\end_layout

\end_inset

 and then binding this symbolic key to the corresponding LyX command.

\end_layout

\begin_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.
 
\end_layout

\begin_layout Standard
First, let us a say a few words about how one ought to think about the relation
 between LyX and LaTeX.
 The thing to understand is that, in a certain sense, LyX doesn't know anything
 about LaTeX.
 Indeed, from LyX's point of view, LaTeX is just one of several 
\begin_inset Quotes eld
\end_inset

backend formats
\begin_inset Quotes erd
\end_inset

 in which it is capable of producing output.
 Other such formats are DocBook, plaintext, and XHTML.
 LaTeX is, of course, a particularly important format, but very little of
 the information LyX has about LaTeX is actually contained in the program
 itself.
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
Some commands are sufficiently complex that they are 
\begin_inset Quotes eld
\end_inset

hardcoded
\begin_inset Quotes erd
\end_inset

 into LyX.
 But the developers generally regard this as a Bad Thing.
\end_layout

\end_inset

 Rather, that information, even for the standard classes like 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
article.cls
\end_layout

\end_inset

, is contained in `layout files'.
 Similarly, LyX itself does not know much about DocBook or XHTML.
 What it knows is contained in layout files.
\end_layout

\begin_layout Standard
You can think of the layout file for a given document class as a translation
 manual between LyX constructs---paragraphs with their corresponding styles,
 certain sorts of insets, etc---and the corresponding LaTeX, DocBook, or
 XHTML constructs.
 Almost everything LyX knows about 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
article.cls
\end_layout

\end_inset

, for example, is contained in the file 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
article.layout
\end_layout

\end_inset

 and in various other files it includes.
 For this reason, anyone intending to write layout files should plan to
 study the existing files.
 A good place to start is with 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
stdsections.inc
\end_layout

\end_inset

, which is included in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
article.layout
\end_layout

\end_inset

, 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
book.layout
\end_layout

\end_inset

, and many of the other layout files for document classes.
 This file is where sections and the like are defined: 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
stdsections.inc
\end_layout

\end_inset

 tells LyX how paragraphs that are marked with the Section, Subsection,
 etc, styles can be translated into corresponding LaTeX, DocBook, and XHTML
 commands and tags.
 The 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
article.layout
\end_layout

\end_inset

 file basically just includes several of these 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
std*.inc
\end_layout

\end_inset

 files.
\end_layout

\begin_layout Standard
Defining the LyX--LaTeX correspondence is not the only thing layout files
 do, though.
 Their other job is to define how the LyX constructs themselves will appear
 on-screen.
 The fact that layout files have these two jobs is often a source of confusion,
 because they are completely separate.
 Telling LyX how to translate a certain paragraph style into LaTeX does
 not tell LyX how to display it; conversely, telling LyX how to display
 a certain paragraph style does not tell LyX how to translate it into LaTeX
 (let alone tell LaTeX how to display it).
 So, in general, when you define a new LyX construct, you must always do
 two quite separate things: (i)
\begin_inset space ~
\end_inset

tell LyX how to translate it into LaTeX and (ii)
\begin_inset space ~
\end_inset

tell LyX how to display it.
\end_layout

\begin_layout Standard
Much the same is true, of course, as regards LyX's other backend formats,
 though XHTML is in some ways different, because in that case LyX 
\emph on
is
\emph default
 able, to some extent, to use information about how it should display a
 paragraph on the screen to output information (in the form of CSS) about
 how the paragraph should be displayed in a browser.
 Even in this case, however, the distinction between what LyX does internally
 and how things are rendered externally remains in force, and the two can
 be controlled separately.
 See 
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:Tags-for-XHTML"

\end_inset

 for the details.
\end_layout

\begin_layout Section
Installing new LaTeX files
\end_layout

\begin_layout Standard
Some installations may not include a LaTeX package or class file that you
 would like to use within LyX.
 For example, you might need FoilTeX, a package for preparing slides for
 overhead projectors.
 Modern LaTeX distributions like TeXLive (2008 or newer) or MiKTeX provide
 a user interface for installing such packages.
 For example, with MiKTeX, you start the program 
\begin_inset Quotes eld
\end_inset

Package
\begin_inset space ~
\end_inset

Manager
\begin_inset Quotes erd
\end_inset

 to get a list of available packages.
 To install one of them, right click on it or use the corresponding toolbar
 button.
\end_layout

\begin_layout Standard
If your LaTeX distribution does not provide such a `package manager', or
 if the package is not available from your distribution, then follow these
 steps to install it manually:
\end_layout

\begin_layout Enumerate
Get the package from 
\begin_inset CommandInset href
LatexCommand href
name "CTAN"
target "http://www.ctan.org/"

\end_inset

 or wherever.
\end_layout

\begin_layout Enumerate
If the package contains a file with the ending 
\begin_inset Quotes eld
\end_inset


\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.ins
\end_layout

\end_inset


\begin_inset Quotes erd
\end_inset

 (is the case for FoilTeX) then open a console, change to the folder of
 this file and execute the command 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
latex foiltex.ins
\end_layout

\end_inset

.
 You have now unpacked the package and have all files to install it.
 Most LaTeX-packages are not packed and you can skip this step.
\end_layout

\begin_layout Enumerate
Now you need to decide if the package should be available for all users
 or only for you.
\end_layout

\begin_deeper
\begin_layout Enumerate
On *nix systems (Linux, OSX, etc.), if you want the new package to be available
 for all users on your system, then install it in your `local' TeX tree,
 otherwise install it in your own `user' TeX tree.
 Where these trees should be created, if they do not already exist, depends
 on your system.
 To find this out, look in the file 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
texmf.cnf
\end_layout

\end_inset

.
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
This is usually in the directory 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\end_inset

, though you can execute the command 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
kpsewhich texmf.cnf
\end_layout

\end_inset

 to locate it.
\end_layout

\end_inset

 The location of the `local' TeX tree is defined by the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
TEXMFLOCAL
\end_layout

\end_inset

 variable; this is usually somewhere like 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
/usr/local/share/texmf
\end_layout

\end_inset

.
 The location of the `user' TeX tree is defined by 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
TEXMFHOME
\end_layout

\end_inset

 and is commonly 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
$HOME/texmf
\end_layout

\end_inset

.
 (If these variables are not predefined, you have to define them.) You'll
 probably need root permissions to create or modify the `local' tree, but
 not for your `user' tree.
\begin_inset Newline newline
\end_inset

In general, it is recommended to install in the user tree because your user
 will not be modified or even overwritten when you upgrade your system.
 It will typically also be backed up together with everything else when
 you backup your home directory (which, of course, you do on a regular basis).
\end_layout

\begin_layout Enumerate
On Windows, if you want the new package to be available for all users on

Now one only need to tell LaTeX that there are new files.
 This depends on the used LaTeX-Distribution:
\end_layout

\begin_deeper
\begin_layout Enumerate
For TeXLive execute the command 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
texhash
\end_layout

\end_inset

 from a console.
 If you installed the package for all users, then you will probably need
 to have root permissions for that.
\end_layout

\begin_layout Enumerate
For MiKTeX, if you have installed the package for all users, start the program
 
\begin_inset Quotes eld
\end_inset

Settings
\begin_inset space ~
\end_inset

(Admin)
\begin_inset Quotes erd
\end_inset

 and press the button marked 
\begin_inset Quotes eld
\end_inset

Refresh FNDB
\begin_inset Quotes erd
\end_inset

.
 Otherwise start the program 
\begin_inset Quotes eld
\end_inset

Settings
\begin_inset Quotes erd
\end_inset

 and do the same.
\end_layout

\end_deeper
\begin_layout Enumerate
Finally, you need to tell LyX that there are new packages available.
 So, in LyX, use the menu 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Tools
\family sans
\SpecialChar \menuseparator
Reconfigure
\end_layout

\end_inset

 and then restart LyX.
\end_layout

\begin_layout Standard
Now the package is installed.
 In our example, the document class 
\begin_inset Flex Code

\begin_inset ERT

\begin_layout Plain Layout

\end_inset

.
 
\end_layout

\begin_layout Standard
If you would like to use a LaTeX document class that is not even listed
 in the menu 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Document\SpecialChar \menuseparator
Settings\SpecialChar \menuseparator
Document Class
\end_layout

\end_inset

, then you need to create a `layout' file for it.
 That is the topic of the next section.
\end_layout

\begin_layout Section
Types of layout files
\end_layout

\begin_layout Standard
This section describes the various sorts of LyX files that contain layout
 information.
 These files describe various paragraph and character styles, determining
 how LyX should display them and how they should be translated into LaTeX,
 DocBook, XHTML, or whatever output format is being used.
 
\end_layout

\begin_layout Standard
We shall try to provide a thorough description of the process of writing
 layout files here.
 However, there are so many different types of documents supported even
 by just LaTeX that we can't hope to cover every different possibility or
 problem you might encounter.
 The LyX users' list is frequented by people with lots of experience with
 layout design who are willing to share what they've learned, so please
 feel free to ask questions there.
\end_layout

\begin_layout Standard
As you prepare to write a new layout, it is extremely helpful to look at
 the layouts distributed with LyX.
 If you write a LyX layout for a LaTeX document class that might also be
 used by others, or write a module that might be useful to others, then
 you should consider posting your layout to the 
\begin_inset CommandInset href
LatexCommand href
name "layout section on the LyX wiki"
target "http://wiki.lyx.org/Layouts/Layouts"

\end_inset

 or even to the LyX developers' list, so that it might be included in LyX
 itself.
\begin_inset Foot

\begin_layout Plain Layout
Note that LyX is licensed under the General Public License, so any material
 that is contributed to LyX must be similarly licensed.
\end_layout

\end_inset


\end_layout

\begin_layout Subsection
Layout modules
\begin_inset CommandInset label
LatexCommand label
name "sub:Layout-modules"

\end_inset


\end_layout

\begin_layout Standard
We have spoken to this point about `layout files'.
 But there are different sorts of files that contain layout information.
 Layout files, strictly so called, have the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.layout
\end_layout

\end_inset

 extension and provide LyX with information about document classes.
 As of LyX 1.6, however, layout information can also be contained in layout
 
\emph on
modules
\emph default
, which have the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.module
\end_layout

\end_inset

 extension.
 Modules are to LaTeX packages much as layouts are to LaTeX classes, and
 some modules—such as the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
endnotes
\end_layout

\end_inset

 module—specifically provide support for one package.
 In a sense, layout modules are similar to included
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
These can have any extension, but by convention have the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.inc
\end_layout

\end_inset

 extension.
\end_layout

\end_inset

 files—files like 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
stdsections.inc
\end_layout

\end_inset

—in that modules are not specific to a given document class but may be used
 with many different classes.
 The difference is that using an included file with 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
article.cls
\end_layout

\end_inset

 requires editing that file.
 Modules, by contrast, are selected in the 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Document\SpecialChar \menuseparator
Settings
\end_layout

\end_inset

 dialog.
\end_layout

\begin_layout Standard
Building modules is the easiest way to get started with layout editing,
 since it can be as simple as adding a single new paragraph style or flex
 inset.
 But modules may, in principle, contain anything a layout file can contain.
\end_layout

\begin_layout Standard
After creating a new module and copying it to the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
layouts/
\end_layout

\end_inset

 folder, you will need to reconfigure and then restart LyX for the module
 to appear in the menu.
 However, changes you make to the module will be seen immediately, if you
 open 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Document\SpecialChar \menuseparator
Settings
\end_layout

\end_inset

, highlight something, and then hit 
\begin_inset Quotes eld
\end_inset

OK
\begin_inset Quotes erd
\end_inset

.
 
\emph on
It is strongly recommended that you save your work before doing this
\emph default
.
 In fact, 
\emph on
it is strongly recommended that you not attempt to edit modules while simultaneo
usly working on actual documents
\emph default
.
 Though of course the developers strive to keep LyX stable in such situations,
 syntax errors and the like in your module file could cause strange behavior.
\end_layout

\begin_layout Subsubsection
Local Layout
\end_layout

\begin_layout Standard
Modules are to LyX as packages are to LaTeX.
 Sometimes, however, you find yourself wanting a specific inset or character
 style just for one document and writing a module that will also be available
 to other documents makes little sense.
 What you need is LyX's 
\begin_inset Quotes eld
\end_inset

Local Layout
\begin_inset Quotes erd
\end_inset

.
\end_layout

\begin_layout Standard
You will find it under 
\family sans
Document\SpecialChar \menuseparator
Settings\SpecialChar \menuseparator
Local Layout
\family default
.
 The large text box allows you to enter anything that you might enter in
 a layout file or module.
 You can think of a document's local layout, in fact, as a module that belongs
 just to it.
 So, in particular, you must enter a 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Format
\end_layout

\end_inset

 tag.
 Any format is acceptable, but one would normally use the format current
 at the time.
 (In LyX 2.0, the current layout format is 35.) You should be aware that local
 layout is not supported by versions of LyX prior to 1.6, so you should not
 use it if you want to be able to export your document to LyX 1.5 or earlier
 (without, that is, losing the local layout information).
 If you wish to be able to export to 1.6---local layout is supported in 1.6,
 though there is no UI for it---then you should use format 11 and, of course,
 use only layout constructs that were available in LyX 1.6.
\end_layout

\begin_layout Standard
When you have entered something in the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Local Layout
\end_layout

\end_inset

 pane, LyX will enable the 
\begin_inset Quotes eld
\end_inset

Validate
\begin_inset Quotes erd
\end_inset

 button at the bottom.
 Clicking this button will cause LyX to determine whether what you have
 entered is valid layout information for the chosen format.
 LyX will report the result but, unfortunately, will not tell you what errors
 there might have been.
 These will be written to the terminal, however, if LyX is started from
 a terminal.
 You will not be permitted to save your local layout until you have entered
 something valid.
\end_layout

\begin_layout Standard
The warnings at the end of the previous section apply here, too.
 Do not play with local layout while you are actually working, especially
 if you have not saved your document.
 That said, using local layout with a test document can be a very convenient
 way to try out layout ideas, or even to start developing a module.
\end_layout

\begin_layout Subsection
Layout for 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
.sty
\end_layout

\end_inset

 files
\end_layout

\begin_layout Standard
There are two situations you are likely to encounter when wanting to support
 a new LaTeX document class, involving style (
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.sty
\end_layout

\end_inset

) files and LaTeX2e class (
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.cls
\end_layout

\end_inset

) .
 Supporting a style file is usually fairly easy.
 Supporting a new class file is a bit harder.
 We'll discuss the former in this section and the latter in the next.
 Similar remarks apply, of course, if you want to support a new DocBook
 DTD.
\end_layout

\begin_layout Standard
The easier case is the one in which your new document class is provided
 as a style file that is to be used in conjunction with an already supported
 document class.
 For the sake of the example, we'll assume that the style file is called
 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
myclass.sty
\end_layout

\end_inset

 and that it is meant to be used with 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
report.cls
\end_layout

\end_inset

, which is a standard class.
 
\end_layout

\begin_layout Standard
Start by copying the existing class's layout file into your local directory:
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
Of course, which directory is your local directory will vary by platform,
 and LyX allows you to specify your local directory on startup, too, using
 the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
-userdir
\end_layout

\end_inset

 option.
\end_layout

\end_inset


\end_layout

\begin_layout LyX-Code
cp report.layout ~/.lyx/layouts/myclass.layout
\end_layout

\begin_layout Standard
Then edit 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
myclass.layout
\end_layout

\end_inset

 and change the line: 
\end_layout

\begin_layout LyX-Code

\backslash
DeclareLaTeXClass{report}
\end_layout

\begin_layout Standard
to read
\end_layout

\begin_layout LyX-Code

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

\begin_layout Standard
Then add:
\end_layout

\begin_layout LyX-Code
Preamble 
\begin_inset Newline newline
\end_inset

    
\backslash
usepackage{myclass}
\begin_inset Newline newline
\end_inset

EndPreamble
\end_layout

\begin_layout Standard
near the top of the file.
\end_layout

\begin_layout Standard
Start LyX and select 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Tools\SpecialChar \menuseparator
Reconfigure
\end_layout

\end_inset

.
 Then restart LyX and try creating a new document.
 You should see "
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
report (myclass)
\end_layout

\end_inset

" as a document class option in the 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Document\SpecialChar \menuseparator
Settings
\end_layout

\end_inset

 dialog.
 It is likely that some of the sectioning commands and such in your new
 class will work differently from how they worked in the base class—
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
report
\end_layout

\end_inset

 in this example—so you can fiddle around with the settings for the different
 sections if you wish.
 The layout information for sections is contained in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
stdsections.inc
\end_layout

\end_inset

, but you do not need to copy and change this file.
 Instead, you can simply add your changes to your layout file, after the
 line 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Input stdclass.inc
\end_layout

\end_inset

, which itself includes 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
stdsections.inc
\end_layout

\end_inset

.
 For example, you might add these lines:
\end_layout

\begin_layout LyX-Code
Style Chapter
\end_layout

\begin_layout LyX-Code
    Font
\end_layout

\begin_layout LyX-Code
        Family Sans
\end_layout

\begin_layout LyX-Code
    EndFont
\end_layout

\begin_layout LyX-Code
End
\end_layout

\begin_layout Standard
to change the font for chapter headings to sans-serif.
 This will override (or, in this case, add to) the existing declaration
 for the Chapter style.
 
\end_layout

\begin_layout Standard
Your new package may also provide commands or environments not present in
 the base class.
 In this case, you will want to add these to the layout file.
 See 
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:TextClass"

\end_inset

 for information on how to do so.
\end_layout

\begin_layout Standard
If 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
myclass.sty
\end_layout

\end_inset

 can be used with several different document classes, and even if it cannot,
 you might find it easiest just to write a module that you can load with
 the base class.
 The simplest possible such module would be:
\end_layout

\begin_layout LyX-Code
#
\backslash
DeclareLyXModule{My Package} 
\end_layout

\begin_layout LyX-Code
#DescriptionBegin 
\end_layout

\begin_layout LyX-Code
#Support for mypkg.sty.
\end_layout

\begin_layout LyX-Code
#DescriptionEnd
\begin_inset Newline newline
\end_inset


\end_layout

\begin_layout LyX-Code
Format 21
\begin_inset Newline newline
\end_inset


\end_layout

\begin_layout LyX-Code
Preamble
\begin_inset Newline newline
\end_inset

    
\backslash
usepackage{mypkg}
\begin_inset Newline newline
\end_inset

EndPreamble
\end_layout

\begin_layout Standard
A more complex module might modify the behavior of some existing constructs
 or define some new ones.
 Again, see 
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:TextClass"

\end_inset

 for discussion.
\end_layout

\begin_layout Subsection
Layout for 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
.cls
\end_layout

\end_inset

 files
\end_layout

\begin_layout Standard
There are two possibilities here.
 One is that the class file is itself based upon an existing document class.
 For example, many thesis classes are based upon 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
book.cls
\end_layout

\end_inset

.
 To see whether yours is, look for a line like
\end_layout

\begin_layout LyX-Code

\backslash
LoadClass{book}
\end_layout

\begin_layout Standard
in the file.
 If so, then you may proceed largely as in the previous section, though
 the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
DeclareLaTeXClass
\end_layout

\end_inset

 line will be different.
 If your new class is 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
thesis
\end_layout

\end_inset

 and it is based upon 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
book
\end_layout

\end_inset

, then the line should read:
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
And it will be easiest if you save the file to 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
thesis.layout
\end_layout

\end_inset

: LyX assumes that the document class has the same name as the layout file.
 
\end_layout

\end_inset


\end_layout

\begin_layout LyX-Code

\backslash
DeclareLaTeXClass[thesis,book]{thesis}
\end_layout

\begin_layout Standard
If, on the other hand, the new class is not based upon an existing class,
 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 then modifying it, if you can do so.
 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.
\end_layout

\begin_layout Subsection
Creating templates
\begin_inset CommandInset label
LatexCommand label
name "sub:Creating-Templates"

\end_inset


\end_layout

\begin_layout Standard
Once you have written a layout file for a new document class, you might
 want to consider writing a 
\emph on
template
\emph default
 for it, too.
 A template acts as a kind of tutorial for your layout, showing how it might
 be used, though containing dummy content.
 You can of course look at the various templates included with LyX for ideas.
\end_layout

\begin_layout Standard
Templates are created just like usual documents: using LyX.
 The only difference is that usual documents contain all possible settings,
 including the font scheme and the paper size.
 Usually a user doesn't want a template to overwrite his preferred settings
 for such parameters.
 For that reason, the designer of a template should remove the corresponding
 commands like 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\backslash
font_roman
\end_layout

\end_inset

 or 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\backslash
papersize
\end_layout

\end_inset

 from the template LyX file.
 This can be done with any simple text-editor, for example 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
vi
\end_layout

\end_inset

 or 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
notepad
\end_layout

\end_inset

.
 
\end_layout

\begin_layout Standard
Put the edited template files you create in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
UserDir/templates/
\end_layout

\end_inset

, copy the ones you use from the global template directory in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LyXDir/templates/
\end_layout

\end_inset

 to the same place, and redefine the template path in the 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Tools\SpecialChar \menuseparator
Preferences\SpecialChar \menuseparator
Paths
\end_layout

\end_inset

 dialog.
\end_layout

\begin_layout Standard
Note, by the way, that there is a template which has a particular meaning:
 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
defaults.lyx
\end_layout

\end_inset

.
 This template is loaded every time you create a new document with 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
File\SpecialChar \menuseparator
New
\end_layout

\end_inset

 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 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Save as Document Defaults
\end_layout

\end_inset

 button.
\end_layout

\begin_layout Subsection
Upgrading old layout files
\end_layout

\begin_layout Standard
The format of layout files changes with each LyX release, so old layout
 files need to be converted to the new format.
 This process has been automated since LyX 1.4: If LyX reads a layout file
 in an older format, it automatically calls the script 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
layout2layout.py
\end_layout

\end_inset

 to convert it to a temporary file in current format.
 The original file is left untouched.
 If you use the layout file often, then, you may want to convert it permanently,
 so that LyX does not have to do so itself every time.
 To do this, you can call the converter manually:
\end_layout

\begin_layout LyX-Code
mv myclass.layout myclass.old
\end_layout

\begin_layout LyX-Code
python LyXDir/scripts/layout2layout.py myclass.old myclass.layout
\end_layout

\begin_layout Standard
You need to replace 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LyXDir
\end_layout

\end_inset

 with the name of your LyX system directory, of course.
\end_layout

\begin_layout Standard
Note that manual conversion does not affect included files, so these will
 have to be converted separately.

\begin_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 too much in one sitting.
 Go have another adult beverage, just for good measure.
\end_layout

\begin_layout Standard
Note that all the tags used in layout files are case-insensitive.

\begin_inset Flex Code

 are really the same tag.
 The possible values are printed in brackets after the feature's name.

\change_unchanged

\end_layout

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

\begin_layout Standard
So, to be as explicit as possible, the form of the layout declaration is:
\end_layout

\begin_layout LyX-Code

\size small
#  
\backslash
DeclareLaTeXClass[class,package.sty]{layout description}
\change_inserted -712698321 1349767329

\size small
#  
\backslash
DeclareCategory{category}
\change_unchanged

\end_layout

\begin_layout Standard
The class need only be specified if the name of the LaTeX class file and
 the name of the layout file are different or if there are packages to load.
 If the name of the class file is not specified, then LyX will simply assume
 that it is the same as the name of the layout file.
\end_layout

\begin_layout Standard
When the text class has been modified to your taste, all you have to do
 is to copy it either to 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LyXDir/layouts/
\end_layout

\end_inset

 or to 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
UserDir/layouts
\end_layout

\end_inset

, run 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Tools\SpecialChar \menuseparator
Reconfigure
\end_layout

\end_inset

, exit LyX and restart.
 Then your new text class should be available along with the others.
\end_layout

\begin_layout Standard
Once the layout file is installed, you can edit it and see your changes
 without having to reconfigure or to restart LyX.
 
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
In versions of LyX prior to 1.6, this was not true.
 As a result, editing layout files was very time consuming, since you had
 constantly to restart LyX to see changes.
\end_layout

\end_inset

 You can force a reload of the current layout by using the LyX function
 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
layout-reload
\end_layout

\end_inset

.
 There is no default binding for this function—though, of course, you can
 bind it to a key yourself.
 But you will normally use this function simply by entering it in the mini-buffe
r.
 
\end_layout

\begin_layout Standard

\emph on
Warning

\begin_inset Flex MenuItem

 is very much an `advanced feature'.
 It is 
\emph on
strongly
\emph default
 recommended that you save your work before using this function.
 In fact, it is 
\emph on
strongly
\emph default
 recommended that you not attempt to edit layout information while simultaneousl
y working on a document that you care about.
 Use a test document.
 Syntax errors and the like in your layout file could cause peculiar behavior.
 In particular, such errors could cause LyX to regard the current layout
 as invalid and to attempt to switch to some other layout.
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
Really bad syntax errors may even caused LyX to exit.
 This is because certain sorts of errors may make LyX unable to read 
\emph on
any
\emph default
 layout information.
 Please be careful.
\end_layout

\end_inset

 The LyX team strives to keep LyX stable in such situations, but safe is
 better than sorry.

\begin_layout Subsection
The Module declaration
\end_layout

\begin_layout Standard
A module must begin with a line like the following:
\end_layout

\begin_layout LyX-Code
#
\backslash
DeclareLyXModule[endnotes.sty]{Endnotes} 
\end_layout

\begin_layout Standard
The mandatory argument, in curly brackets, is the name of the module, as
 it should appear in 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Document\SpecialChar \menuseparator
Settings\SpecialChar \menuseparator
Modules
\end_layout

\end_inset

.
 The argument in square brackets is optional: It declares any LaTeX packages
 on which the module depends.
 It is also possible to use the form 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
from->to
\end_layout

\end_inset

 as an optional argument, which declares that the module can only be used
 when there exists a conversion chain between the formats `
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
from
\end_layout

\end_inset

' and `
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
to
\end_layout

\end_inset

'.
\end_layout

\begin_layout Standard
The module declaration should then be followed by lines like the following
\begin_inset Foot
status collapsed

\begin_layout Plain Layout
Preferably in English if the module should be published with LyX.
 This description will appear in the list of messages to be translated and
 will be thus translated with the next interface update.

\begin_layout LyX-Code

\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Document\SpecialChar \menuseparator
Settings\SpecialChar \menuseparator

\end_layout

\end_inset

 to provide the user with information about what the module does.
 The 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Requires
\end_layout

\end_inset

 line is used to identify other modules with which this one must be used;
 the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Excludes
\end_layout

\end_inset

 line is used to identify modules with which this one may not be used.
 Both are optional, and, as shown, multiple modules should be separated
 with the pipe symbol: |.
 Note that the required modules are treated disjunctively: 
\emph on
at least one
\emph default
 of the required modules must be used.
 Similarly, 
\emph on
no
\emph default
 excluded module may be used.
 Note that modules are identified here by their filenames without the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.module
\end_layout

\end_inset

 extension.
 So 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
somemodule

 is really 
\begin_inset Flex Code

\begin_layout Plain Layout

\begin_layout Subsection

\end_layout

\begin_layout Standard
This tag was introduced with LyX
\begin_inset space ~

1.4.0.

\begin_inset space ~

\end_layout

\end_inset

.
 The format for the present version of LyX is format 35.
 But each version of LyX is capable of reading earlier versions' layout
 files, just as they are capable of reading files produced by earlier versions
 of LyX.
 There is, however, no provision for converting to earlier formats.

] Usually LyX does not allow you to leave a paragraph empty, since it would
 lead to empty LaTeX output.
 There are some cases where this could be desirable however: in a letter
 template, the required fields can be provided as empty fields, so that
 people do not forget them; in some special classes, a style can be used
 as some kind of break, which does not contain actual text.

Internationalization of Paragraph Styles
\end_layout

\begin_layout Standard
LyX has long supported internationalization of layout information, but,
 until version 2.0, this applied only to the user interface and not to, say,
 PDF output.
 Thus, French authors were forced to resort to ugly hacks if they wanted
 `
\lang french
Théorème
\lang english
 1' instead of `Theorem 1'.
 Thanks to Georg Baum, that is no longer the case.
\end_layout

\begin_layout Standard
If a 
\begin_inset Flex Code
status collapsed

\begin_inset Flex Code

\end_inset

 and 
\begin_inset Flex Code

 to support non-English and even multi-language documents correctly.
 The following excerpt (from the 
\begin_inset Flex Code

 and 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\end_inset

 tags, but in practice they will typically look as they do here.
 The key to correct translation of the typeset text is the definition of
 the LaTeX command 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\backslash
claimname
\end_layout

\end_inset

 and its use in 
\begin_inset Flex Code

\end_inset

.
 
\end_layout

\begin_layout Standard
The 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LangPreamble
\end_layout

\end_inset

 tag provides for internationalization based upon the overall language of
 the document.
 The contents of the tag will be included in the preamble, just as with
 the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Preamble
\end_layout

\end_inset

 tag.
 What makes it special is the use of the 
\begin_inset Quotes eld
\end_inset

function
\begin_inset Quotes erd
\end_inset

 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
_()
\end_layout

\end_inset

, which will be replaced, when LyX produces LaTeX output, with the translation
 of its argument into the document language.
\end_layout

\begin_layout Standard
The 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
BabelPreamble
\end_layout

\end_inset

 tag is more complex, since it is meant to provide support for multi-language
 documents and so offers an interface to the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
babel
\end_layout

\end_inset

 package.
 Its contents will be added to the preamble once for each language that
 appears in the document.
 In this case, the argument to 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
_()
\end_layout

\end_inset

 will be replaced with its translation into the language in question; the
 expression 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
$$lang
\end_layout

\end_inset

 is replaced by the language name (as used by the babel package).
\end_layout

\begin_layout Standard
A German document that also included a French section would thus have the
 following in the preamble:
\end_layout

\begin_layout LyX-Code

\backslash
addto
\backslash
captionsfrench{
\backslash
renewcommand{
\backslash
claimname}{Affirmation}}
\begin_inset Newline newline

\backslash

\begin_inset Newline newline
\end_inset


\backslash

claimname}{Behauptung}
\end_layout

\begin_layout Standard
LaTeX and 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
babel
\end_layout

\end_inset

 will then conspire to produce the correct text in the output.
\end_layout

\begin_layout Standard
One important point to note here is that the translations are provided by
 LyX itself, through the 
\change_inserted -195340706 1334775793

\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\end_layout

\end_inset


\change_deleted -195340706 1334775793
same mechanism it uses for internationalization of the user interface
\change_unchanged
.
 This means, in effect, that 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LangPreamble
\end_layout

\end_inset

 and 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
BabelPreamble
\end_layout

\end_inset

 are really only of use in layout files that are provided with LyX, since
 text entered in user-created layout files will not be seen by LyX's internation
alization routines
\change_inserted -195340706 1334775793
 unless the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\change_inserted -195340706 1334775793
layouttranslations
\end_layout

\end_inset

 file is modified accordingly
\change_unchanged
.
 That said, however, any layout created with the intention that it will
 be included with LyX should use these tags where appropriate.

\change_inserted -195340706 1334775793
 Please note that the paragraph style translations provided by LyX will
 never change with a minor update (e.g.
 from version 2.1.x to 2.1.y).
 It is however quite likely that a major update (e.g.
 from 2.0.x to 2.1.y) will introduce new translations or corrections.

 On top of that there is a new type,

 and nowhere else.
 Note however that the

 used in non-built in float types.

\end_layout

\begin_layout Itemize
character style (
\begin_inset Flex Code

\end_layout

\begin_layout Itemize
user custom (
\begin_inset Flex Code

\begin_layout Plain Layout

 An obvious example is an endnote inset, which is defined in the

\begin_inset Flex Code

\begin_layout Plain Layout

\end_layout

\end_inset

 turns on emphasis, and 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
no_emph

 turns it off.

 context are generally inherited from the surrounding context.
 So 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
no_emph

 would turn off the emphasis that was anyway in effect, say, in a theorem

Citation format description
\end_layout

\begin_layout Standard
The 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
CiteFormat
\end_layout

\end_inset

 blocks are used to describe how bibliographic information should be displayed,
 both within LyX itself (in the citation dialog and in tooltips, for example)
 and in XHTML output.
 Such a block might look like this:
\end_layout

\begin_layout LyX-Code
CiteFormat
\end_layout

\begin_layout LyX-Code
 article ...
\end_layout

\begin_layout LyX-Code
 book ...
\end_layout

\begin_layout LyX-Code
End
\end_layout

\begin_layout Standard
The individual lines define how the bibliographic information associated
 with an article or book, respectively, is to be displayed, and such a definitio
n can be given for any `entry type' that might be present in a BibTeX file.
 LyX defines a default format in the source code that will be used if no
 specific definition has been given.
 LyX predefines several formats in the file 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
stdciteformats.inc
\end_layout

\end_inset

, which is included in most of LyX's document classes.
\end_layout

\begin_layout Standard
The definitions use a simple language that allows BibTeX keys to be replaced
 with their values.
 Keys should be enclosed in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
%
\end_layout

\end_inset

 signs, e.g.: 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
%author%
\end_layout

\end_inset

.
 So a simple definition might look like this:
\end_layout

\begin_layout LyX-Code
misc %author%, 
\begin_inset Quotes eld
\end_inset

%title
\begin_inset Quotes erd
\end_inset

.
\end_layout

\begin_layout Standard
This would print the author, followed by a comma, followed by the title,
 in quotes, followed by a period.
\end_layout

\begin_layout Standard
Of course, sometimes you may want to print a key only if it exists.
 This can be done by using a conditional construction, such as: 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
{%volume%[[vol.
\begin_inset space ~
\end_inset

%volume%]]}
\end_layout

\end_inset

.
 This says: If the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
volume
\end_layout

\end_inset

 key exists, then print 
\begin_inset Quotes eld
\end_inset

vol.
\begin_inset space ~
\end_inset


\begin_inset Quotes erd
\end_inset

 followed by the volume key.
 It is also possible to have an else clause in the conditional, such as:
\begin_inset Newline newline
\end_inset


\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
{%author%[[%author%]][[%editor%, ed.]]}
\end_layout

\end_inset

.
\begin_inset Newline newline
\end_inset

Here, the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
author
\end_layout

\end_inset

 key is printed if it exists; otherwise, the editor key is printed, followed
 by 
\begin_inset Quotes eld
\end_inset

,
\begin_inset space ~
\end_inset

ed.
\begin_inset Quotes erd
\end_inset

 Note that the key is again enclosed in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
%
\end_layout

\end_inset

 signs; the entire conditional is enclosed in braces; and the if and else
 clauses are enclosed in double brackets, 
\begin_inset Quotes eld
\end_inset


\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
[[
\end_layout

\end_inset


\begin_inset Quotes eld
\end_inset

 and 
\begin_inset Quotes eld
\end_inset


\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
]]
\end_layout

\end_inset


\begin_inset Quotes erd
\end_inset

.
 There must be no space between any of these.
\end_layout

\begin_layout Standard
There is one other piece of syntax available in definitions, which looks
 like this: 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
{!<i>!}
\end_layout

\end_inset

.
 This defines a piece of formatting information that is to be used when
 creating 
\begin_inset Quotes eld
\end_inset

rich text
\begin_inset Quotes erd
\end_inset

.
 Obviously, we do not want to output HTML tags when writing plain text,
 so they should be wrapped in 
\begin_inset Quotes eld
\end_inset

{!
\begin_inset Quotes erd
\end_inset

 and 
\begin_inset Quotes eld
\end_inset

!}
\begin_inset Quotes erd
\end_inset

.
\end_layout

\begin_layout Standard
Two special sorts of definitions are also possible in a 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
CiteFormat
\end_layout

\end_inset

 block.
 An example of the first would be:
\end_layout

\begin_layout LyX-Code
!quotetitle 
\begin_inset Quotes eld
\end_inset

%title%
\begin_inset Quotes erd
\end_inset


\end_layout

\begin_layout Standard
This is an abbreviation, or macro, and it can be used by treating it as
 if it were a key: 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
%!quotetitle%
\end_layout

\end_inset

.
 LyX will treat 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
%!quotetitle%
\end_layout

\end_inset

 exactly as it would treat its definition.
 So, let us issue the obvious 
\emph on
warning
\emph default
.
 Do not do this:
\end_layout

\begin_layout LyX-Code
!funfun %funfun%
\end_layout

\begin_layout Standard
or anything like it.
 LyX shouldn't go into an infinite loop, but it may go into a long one before
 it gives up.
\end_layout

\begin_layout Standard
The second sort of special definition might look like this:
\end_layout

\begin_layout LyX-Code
_pptext pp.
\end_layout

\begin_layout Standard
This defines a translatable piece of text, which allows relevant parts of
 the bibliography to be translated.
 It can be included in a definition by treating it as a key: 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
%_pptext%
\end_layout

\end_inset

.
 Several of these are predefined in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
stdciteformats.inc
\end_layout

\end_inset

.
 Note that these are not macros, in the sense just defined.
 They will not be expanded.
\end_layout

\begin_layout Standard
So here then is an example that use all these features:
\begin_inset VSpace defskip
\end_inset


\end_layout

\begin_layout Standard
\noindent

\family typewriter
!authoredit {%author%[[%author%, ]][[{%editor%[[%editor%, %_edtext%, ]]}]]}
\end_layout

\begin_layout Standard
\begin_inset VSpace defskip
\end_inset

This defines a macro that prints the author, followed by a comma, if the
 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
author
\end_layout

\end_inset

 key is defined, or else prints the name of the editor, followed by the
 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
_edtext
\end_layout

\end_inset

 or its translation (it is by default 
\begin_inset Quotes eld
\end_inset

ed.
\begin_inset Quotes erd
\end_inset

), if the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
editor
\end_layout

\end_inset

 key is defined.
 Note that this is in fact defined in 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
stdciteformats.inc
\end_layout

\end_inset

, so you can use it in your own definitions, or re-definitions, if you load
 that file first.
\end_layout

\begin_layout Section
\begin_inset CommandInset label
LatexCommand label
name "sec:Tags-for-XHTML"

\end_inset

Tags for XHTML output
\end_layout

\begin_layout Standard
As with LaTeX or DocBook, the format of LyX's XHTML output is also controlled
 by layout information.
 In general, LyX provides sensible defaults and, as mentioned earlier, it
 will even construct default CSS style rules from the other layout tags.
 For example, LyX will attempt to use the information provided in the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Font
\end_layout

\end_inset

 declaration for the Chapter style to write CSS that will appropriately
 format chapter headings.
\end_layout

\begin_layout Standard
In many cases, then, you may not have to do anything at all to get acceptable
 XHTML output for your own environments, custom insets, and so forth.
 But in some cases you will, and so LyX provides a number of layout tags
 that can be used to customize the XHTML and CSS that are generated.
\end_layout

\begin_layout Standard
Note that there are two tags, 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
HTMLPreamble
\end_layout

\end_inset

 and 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\end_layout

\end_inset

 that may appear outside style and inset declarations.

Paragraph styles
\end_layout

\begin_layout Standard
The sort of XHTML LyX outputs for a paragraph depends upon whether we are
 dealing with a normal paragraph, a command, or an environment, where this
 is itself determined by the contents of the corresponding 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LaTeXType
\end_layout

\end_inset

 tag.
 
\end_layout

\begin_layout Standard
For a command or normal paragraph, the output XHTML has the following form:
\end_layout

\begin_layout LyX-Code
<tag attr=
\begin_inset Quotes erd
\end_inset

value
\begin_inset Quotes erd
\end_inset

>
\end_layout

\begin_layout LyX-Code
<labeltag attr=
\begin_inset Quotes erd
\end_inset

value
\begin_inset Quotes erd
\end_inset

>Label</labeltag>
\end_layout

\begin_layout LyX-Code
Contents of the paragraph.
\end_layout

\begin_layout LyX-Code
</tag>
\end_layout

\begin_layout Standard
The label tags are of course omitted if the paragraph does not have a label.
\end_layout

\begin_layout Standard
For an environment that is not some sort of list, the XHTML takes this form:
\end_layout

\begin_layout LyX-Code
<tag attr=
\begin_inset Quotes erd
\end_inset

value
\begin_inset Quotes erd
\end_inset

>
\end_layout

\begin_layout LyX-Code
<itemtag attr=
\begin_inset Quotes erd

value
\begin_inset Quotes erd
\end_inset

><labeltag attr=
\begin_inset Quotes erd

value
\begin_inset Quotes erd

>Environment Label</labeltag>First paragraph.</itemtag>
\end_layout

\begin_layout LyX-Code
<itemtag>Second paragraph.</itemtag>
\end_layout

\begin_layout LyX-Code
</tag>
\end_layout

\begin_layout Standard
Note that the label is output only for the first paragraph, as it should
 be for a theorem, for example.
 
\end_layout

\begin_layout Standard
For a list, we have one of these forms:
\end_layout

\begin_layout LyX-Code

\end_inset

 Which order we get depends upon the setting of

\end_layout

\end_inset

: If 
\begin_inset Flex Code
status collapsed

 is false (the default), you get the first of these, with the label within
 the item; if true, you get the second, with the label outside the item.
\end_layout

\begin_layout Standard
The specific tags and attributes output for each paragraph type can be controlle
d by means of the layout tags we are about to describe.
 As mentioned earlier, however, LyX uses sensible defaults for many of these,
 so you often may not need to do very much to get good XHTML output.
 Think of the available tags as there so you can tweak things to your liking.

 (See

\end_layout

\begin_layout Standard
The use of material from sources external to LyX is covered in detail in
 the 
\emph on
Embedded Objects
\emph default
 manual.
 This part of the manual covers what needs to happen behind the scenes for
 new sorts of material to be included.
\end_layout

\begin_layout Section
How does it work?
\end_layout

\begin_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, various
 raster format images, chess diagrams, and LilyPond music notation.
 You can check the actual list by using the menu 
\begin_inset Flex MenuItem
status collapsed

\begin_layout Plain Layout
Insert\SpecialChar \menuseparator
File\SpecialChar \menuseparator
External Material
\end_layout

\end_inset

.
 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.
\end_layout

\begin_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 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
Xfig
\end_layout

\end_inset

.
 The Xfig application itself works on an original file with the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.fig
\end_layout

\end_inset

 extension.
 Within Xfig, you create and change your figure, and when you are done,
 you save the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
fig
\end_layout

\end_inset

-file.
 When you want to include the figure in your document, you invoke 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
transfig
\end_layout

\end_inset

 in order to create a PostScript file that can readily be included in your
 LaTeX file.
 In this case, the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.fig
\end_layout

\end_inset

 file is the original file, and the PostScript file is the produced file.
\end_layout

\begin_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 a plain text file, it is not exactly an award-winn
ing idea to include the figure as raw PostScript.
 Instead, you would 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 parametri
zed on the different export formats that LyX supports.
\end_layout

\begin_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 Xfig on the original
 file with a single click from within the external material dialog in LyX,
 and also preview the produced PostScript file with Ghostview 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.

The external template configuration file
\end_layout

\begin_layout Standard
It is relatively easy to add custom external template definitions to LyX.
 However, be aware that doing this in an careless manner most probably 
\emph on
will
\emph default
 introduce an easily exploitable security hole.
 So before you do this, please read the discussion about security in section
 
\begin_inset CommandInset ref

\end_inset

.
\end_layout

\begin_layout Standard
Having said that, we encourage you to submit any interesting templates that
 you create.
 
\end_layout

\begin_layout Standard
The external templates are defined in the 
\begin_inset Flex Code

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

\begin_layout Enumerate
Relative and absolute file names should remain relative or absolute, respectivel
y.
 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.
\end_layout

\begin_layout Enumerate
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.
\end_layout

\begin_layout Standard
So which path macro should be used in new template definitions? The rule
 is not difficult:
\end_layout

\begin_layout Itemize
Use 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
$$AbsPath
\end_layout

\end_inset

 if an absolute path is required.
\end_layout

\begin_layout Itemize
Use 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
$$AbsOrRelPathMaster
\end_layout

\end_inset

 if the substituted string is some kind of LaTeX input.
\end_layout

\begin_layout Itemize
Else use 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
$$AbsOrRelPathParent
\end_layout

\end_inset

 in order to preserve the user's choice.
\end_layout

\begin_layout Standard
There are special cases where this rule does not work and e.
\begin_inset space \thinspace{}
\end_inset

g.
\begin_inset space \space{}
\end_inset

relative names are needed, but normally it will work just fine.
 One example for such a case is the command 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
ReferencedFile latex "$$AbsOrRelPathMaster$$Basename.pstex_t"
\end_layout

\end_inset

 in the XFig template above: We can't use the absolute name because the
 copier for 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.pstex_t
\end_layout

\end_inset

 files needs the relative name in order to rewrite the file content.

\end_layout

\begin_layout Standard
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 definitely want to avoid.
\end_layout

\begin_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 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
execvp
\end_layout

\end_inset

-system call rather than the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
system
\end_layout

\end_inset

 system-call, so it's not possible to execute arbitrary commands from the
 filename or parameter section via the shell.
\end_layout

\begin_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.
 
\end_layout

\begin_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 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
execvp
\end_layout

\end_inset

 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.
\end_layout

\begin_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 knowledgeable 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.
