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

1166 menu will open them!
1169 \begin_layout Section
1170 Running LyX with multiple configurations
1173 \begin_layout Standard
1174 The configuration freedom of the local configuration directory may not suffice
1175 if you want to have more than one configuration at your disposal.
1176 For example, you may want to be use different key bindings or printer settings
1178 You can achieve this by having several such directories.
1179 You then specify which directory to use at run-time.
1182 \begin_layout Standard
1183 Invoking LyX with the command line switch
1184 \begin_inset Flex CharStyle:Code
1187 \begin_layout Plain Layout
1197 instructs the program to read the configuration from that directory, and
1198 not from the default directory.
1199 (You can determine the default directory by running LyX without the
1200 \begin_inset Flex CharStyle:Code
1203 \begin_layout Plain Layout
1209 switch.) If the specified directory does not exist, LyX offers to create
1210 it for you, just like it does for the default directory on the first time
1211 you run the program.
1212 You can modify the configuration options in this additional user directory
1213 exactly as you would for the default directory.
1214 These directories are completely independent (but read on).
1215 Note that setting the environment variable
1216 \begin_inset Flex CharStyle:Code
1219 \begin_layout Plain Layout
1225 to some value has exactly the same effect.
1228 \begin_layout Standard
1229 Having several configurations also requires more maintenance: if you want
1230 to add a new layout to
1231 \begin_inset Flex CharStyle:Code
1234 \begin_layout Plain Layout
1240 which you want available from all your configurations, you must add it
1241 to each directory separately.
1242 You can avoid this with the following trick: after LyX creates the additional
1243 directory, most of the subdirectories (see above) are empty.
1244 If you want the new configuration to mirror an existing one, replace the
1245 empty subdirectory with a symbolic link to the matching subdirectory in
1246 the existing configuration.
1248 \begin_inset Flex CharStyle:Code
1251 \begin_layout Plain Layout

1651 Since all conversions from one format to another take place in LyX's temporary
1652 directory, it is sometimes necessary to modify a file before copying it
1653 to the temporary directory in order that the conversion may be performed.
1657 \begin_layout Plain Layout
1658 For example, the file may refer to other files—images, for example—using
1659 relative file names, and these may become invalid when the file is copied
1660 to the temporary directory.
1665 This is done by a Copier: It copies a file to (or from) the temporary directory
1666 and may modify it in the process.
1669 \begin_layout Standard
1670 The definitions of the copiers may use four variables:
1673 \begin_layout Labeling
1674 \labelwidthstring 00.00.0000

2341 You do not have to define converters for all formats between which you want
2343 For example, you will note that there is no `LyX to PostScript' converter,
2344 but LyX will export PostScript.
2345 It does so by first creating a LaTeX file (no converter needs to be defined
2346 for this) which is then converted to DVI using the `LaTeX to DVI' converter,
2347 and finally converting the resulting DVI file to PostScript.
2348 LyX finds such `chains' of converters automatically, and it will always
2349 choose the shortest possible chain.
2350 You can, though, still define multiple conversion methods between file
2352 For example, the standard LyX configuration provides three ways to convert
2353 LaTeX to PDF: Directly, using
2354 \begin_inset Flex CharStyle:MenuItem
2357 \begin_layout Plain Layout
2363 ; via (DVI and) PostScript, using

2367 \begin_layout Plain Layout
2374 \begin_inset Flex CharStyle:MenuItem
2377 \begin_layout Plain Layout
2384 To define such alternate chains, you must define multiple target `file
2385 formats', as described in section
2386 \begin_inset CommandInset ref
2388 reference "sec:Formats"
2393 For example, in the standard configuration, the formats named

2471 Notice that these translations will work, but do contain a few flaws.
2472 In particular, all dialogs have been designed with the English text in
2473 mind, which means that some of the translated text will be too large to
2474 fit within the space allocated.
2475 This is only a display problem and will not cause any harm.
2476 Also, you will find that some of the translations do not define shortcut
2477 keys for everything.
2478 Sometimes, there are simply not enough free letters to do it.
2479 Other times, the translator just hasn't got around to doing it yet.

4757 There is a second way to add support for international characters through

4760 Here, we'll explain how to create a really simple dead-key to illustrate

4820 \begin_inset Flex CharStyle:MenuItem
4823 \begin_layout Plain Layout
4829 -key followed by a letter, that letter will have a circumflex accent on

4849 produces the letter:

4863 \begin_inset Flex CharStyle:MenuItem
4866 \begin_layout Plain Layout
4873 \begin_inset Quotes erd

4877 \begin_inset Quotes eld
4881 \begin_inset Flex CharStyle:MenuItem

4894 never takes a circumflex accent.
4896 \begin_inset Flex CharStyle:MenuItem
4899 \begin_layout Plain Layout
4905 after a dead-key produces the bare-accent.
4906 Please note this last point! If you bind a key to a dead-key, you'll need
4907 to rebind the character on that key to yet another key.

5248 Installing New Document Classes
5256 \begin_layout Standard
5257 In this chapter, we describe the procedures for creating and installing
5258 new LyX layout and template files, as well as offer a refresher on correctly
5259 installing new LaTeX document classes.
5263 \begin_layout Standard
5264 First, let us a say a few words about how one ought to think about the relation
5265 between LyX and LaTeX.
5266 The thing to understand is that, in a certain sense, LyX doesn't know anything
5268 Indeed, from LyX's point of view, LaTeX is just one of several
5269 \begin_inset Quotes eld
5273 \begin_inset Quotes erd
5276 in which it is capable of producing output.
5277 Other such formats are DocBook, plaintext, and XHTML.
5278 LaTeX is, of course, a particularly important format, but very little of
5279 the information LyX has about LaTeX is actually contained in the program
5284 \begin_layout Plain Layout
5285 Some commands are sufficiently complex that they are
5286 \begin_inset Quotes eld
5290 \begin_inset Quotes erd
5294 But the developers generally regard this as a Bad Thing.
5299 Rather, that information, even for the standard classes like
5300 \begin_inset Flex CharStyle:Code
5303 \begin_layout Plain Layout
5309 , is contained in `layout files'.
5310 Similarly, LyX itself does not know much about DocBook or XHTML.
5311 What it knows is contained in layout files.
5314 \begin_layout Standard
5315 You can think of the layout file for a given document class as a translation
5316 manual between LyX constructs---paragraphs with their corresponding styles,
5317 certain sorts of insets, etc---and the corresponding LaTeX, DocBook, or
5319 Almost everything LyX knows about
5320 \begin_inset Flex CharStyle:Code
5323 \begin_layout Plain Layout
5329 , for example, is contained in the file
5330 \begin_inset Flex CharStyle:Code
5333 \begin_layout Plain Layout
5339 and in various other files it includes.
5340 For this reason, anyone intending to write layout files should plan to
5341 study the existing files.
5342 A good place to start is with
5343 \begin_inset Flex CharStyle:Code
5346 \begin_layout Plain Layout
5352 , which is included in
5353 \begin_inset Flex CharStyle:Code
5356 \begin_layout Plain Layout
5363 \begin_inset Flex CharStyle:Code
5366 \begin_layout Plain Layout
5372 , and many of the other layout files for document classes.
5373 This file is where sections and the like are defined:
5374 \begin_inset Flex CharStyle:Code
5377 \begin_layout Plain Layout
5383 tells LyX how paragraphs that are marked with the Section, Subsection,
5384 etc, styles can be translated into corresponding LaTeX, DocBook, and XHTML
5387 \begin_inset Flex CharStyle:Code
5390 \begin_layout Plain Layout
5396 file basically just includes several of these
5397 \begin_inset Flex CharStyle:Code
5400 \begin_layout Plain Layout
5409 \begin_layout Standard
5410 Defining the LyX--LaTeX correspondence is not the only thing layout files
5412 Their other job is to define how the LyX constructs themselves will appear
5414 The fact that layout files have these two jobs is often a source of confusion,
5415 because they are completely separate.
5416 Telling LyX how to translate a certain paragraph style into LaTeX does
5417 not tell LyX how to display it; conversely, telling LyX how to display
5418 a certain paragraph style does not tell LyX how to translate it into LaTeX
5419 (let alone tell LaTeX how to display it).
5420 So, in general, when you define a new LyX construct, you must always do
5421 two quite separate things: (i)
5422 \begin_inset space ~
5425 tell LyX how to translate it into LaTeX and (ii)
5426 \begin_inset space ~
5429 tell LyX how to display it.
5432 \begin_layout Standard
5433 Much the same is true, of course, as regards LyX's other backend formats,
5434 though XHTML is in some ways different, because in that case LyX
5438 able, to some extent, to use information about how it should display a
5439 paragraph on the screen to output information (in the form of CSS) about
5440 how the paragraph should be displayed in a browser.
5441 Even in this case, however, the distinction between what LyX does internally
5442 and how things are rendered externally remains in force, and the two can
5443 be controlled separately.

5455 Installing new LaTeX files
5458 \begin_layout Standard
5459 Some installations may not include a LaTeX package or class file that you
5460 would like to use within LyX.
5461 For example, you might need FoilTeX, a package for preparing slides for
5462 overhead projectors.
5463 Modern LaTeX distributions like TeXLive (2008 or newer) or MiKTeX provide
5464 a user interface for installing such packages.
5465 For example, with MiKTeX, you start the program
5466 \begin_inset Quotes eld
5470 \begin_inset Quotes erd
5473 to get a list of available packages.
5474 To install one, right click on it or use the toolbar button to install
5479 \begin_layout Standard
5480 If your LaTeX distribution doesn't provide such a `package manager', or
5481 if the file is not available from your distribution, then you can follow
5482 these steps to install it manually.

5498 You can install the package in several different places.
5499 If you want it to be available for all users on your system, then you should
5500 install it in your `local' TeX tree; if you want (or need) it to be available
5501 just for you, then you can install it in your own `user' TeX tree.
5502 Where these trees should be created, if they do not already exist, depends
5503 upon the details of your system.
5504 To find out where they are, look in the file
5505 \begin_inset Flex CharStyle:Code

5519 This usually lives in the directory

5544 The location of the `local' TeX tree is defined by the
5545 \begin_inset Flex CharStyle:Code
5548 \begin_layout Plain Layout
5554 variable; this is usually somewhere like
5555 \begin_inset Flex URL

5577 \begin_inset Flex CharStyle:Code
5580 \begin_layout Plain Layout
5587 (If these variables are not predefined, you can define them.) You'll probably
5588 need root permissions to create or modify the `local' tree, but your `user'
5589 tree shouldn't have such limitations.

5710 If you are lucky, your package will have been provided as a so-called `TDS'
5711 (TeX Directory Structure) zip file.
5712 To install it, you want to unzip it from the top of your tree.
5713 So, for example, you can copy the file

5717 \begin_layout Plain Layout
5724 \begin_inset Flex CharStyle:Code
5727 \begin_layout Plain Layout

5744 This will extract the needed files and copy them where they need to be.
5745 \begin_inset Newline newline
5748 If you do not have a TDS file, then you have to do this manually.

5847 ) and then restart LyX.

5875 What if there isn't a layout file is available for your new document class?
5876 Then, unfortunately, LyX will know nothing about it until you create a
5877 layout file yourself (or get someone else to do it).
5878 That is the topic of the next section.
5881 \begin_layout Section
5882 Types of layout files
5885 \begin_layout Standard
5886 This section describes the various sorts of LyX files that contain layout
5888 These files describe various paragraph and character styles, determining
5889 how LyX should display them and how they should be translated into LaTeX,
5890 DocBook, XHTML, or whatever output format is being used.
5894 \begin_layout Standard
5895 We shall try to provide a thorough description of the process of writing
5897 However, there are so many different types of documents supported even
5898 by just LaTeX that we can't hope to cover every different possibility or
5899 problem you might encounter.
5900 The LyX users' list is frequented by people with lots of experience with
5901 layout design who are willing to share what they've learned, so please
5902 feel free to ask questions there.
5905 \begin_layout Standard
5906 As you prepare to write a new layout, it is extremely helpful to look at
5907 the layouts distributed with LyX.
5908 If you write a LyX layout for a LaTeX document class that might also be
5909 used by others, or write a module that might be useful to others, then
5910 you should consider posting your layout to the
5911 \begin_inset CommandInset href
5913 name "layout section on the LyX wiki"
5914 target "http://wiki.lyx.org/Layouts/Layouts"
5918 or even to the LyX developers' list, so that it might be included in LyX
5923 \begin_layout Plain Layout
5924 Note that LyX is licensed under the General Public License, so any material
5925 that is contribued to LyX must be similarly licensed.
5933 \begin_layout Subsection
5935 \begin_inset CommandInset label
5937 name "sub:Layout-modules"
5944 \begin_layout Standard
5945 We have spoken to this point about `layout files'.
5946 But there are different sorts of files that contain layout information.
5947 Layout files, strictly so called, have the
5948 \begin_inset Flex CharStyle:Code
5951 \begin_layout Plain Layout
5957 extension and provide LyX with information about document classes.
5958 As of LyX 1.6, however, layout information can also be contained in layout
5964 \begin_inset Flex CharStyle:Code
5967 \begin_layout Plain Layout
5974 Modules are to LaTeX packages much as layouts are to LaTeX classes, and
5975 some modules—such as the
5976 \begin_inset Flex CharStyle:Code
5979 \begin_layout Plain Layout
5985 module—specifcally provide support for one package.
5986 In a sense, layout modules are similar to included
5990 \begin_layout Plain Layout
5991 These can have any extension, but by convention have the
5992 \begin_inset Flex CharStyle:Code
5995 \begin_layout Plain Layout
6007 \begin_inset Flex CharStyle:Code
6010 \begin_layout Plain Layout
6016 —in that modules are not specific to a given document class but may be used
6017 with many different classes.
6018 The difference is that using an included file with
6019 \begin_inset Flex CharStyle:Code
6022 \begin_layout Plain Layout
6028 requires editing that file.
6029 Modules, by contrast, are selected in the
6030 \begin_inset Flex CharStyle:MenuItem
6033 \begin_layout Plain Layout
6034 Document\SpecialChar \menuseparator
6043 \begin_layout Standard
6044 Building modules is the easiest way to get started with layout editing,
6045 since it can be as simple as adding a single new paragraph style or flex
6047 But modules may, in principle, contain anything a layout file can contain.
6050 \begin_layout Standard
6051 After creating a new module and copying it to the
6052 \begin_inset Flex CharStyle:Code
6055 \begin_layout Plain Layout
6061 folder, you will need to reconfigure and then restart LyX for the module
6062 to appear in the menu.
6063 However, changes you make to the module will be seen immediately, if you
6065 \begin_inset Flex CharStyle:MenuItem
6068 \begin_layout Plain Layout

6075 , highlight something, and then hit
6076 \begin_inset Quotes eld
6080 \begin_inset Quotes erd
6086 It is strongly recommended that you save your work before doing this
6091 it is strongly recommended that you not attempt to edit modules while simultaneo
6092 usly working on actual documents
6095 Though of course the developers strive to keep LyX stable in such situations,
6096 syntax errors and the like in your module file could cause strange behavior.
6099 \begin_layout Subsection

6113 \begin_layout Standard
6114 There are two situations you are likely to encounter when wanting to support
6115 a new LaTeX document class, involving LaTeX2e class (

6136 Supporting a style file is usually fairly easy.
6137 Supporting a new class file is a bit harder.
6138 We'll discuss the former in this section and the latter in the next.
6139 Similar remarks apply, of course, if you want to support a new DocBook
6143 \begin_layout Standard
6144 The easier case is the one in which your new document class is provided
6145 as a style file that is to be used in conjunction with an already supported
6147 For the sake of the example, we'll assume that the style file is called
6149 \begin_inset Flex CharStyle:MenuItem
6152 \begin_layout Plain Layout
6158 and that it is meant to be used with
6159 \begin_inset Flex CharStyle:MenuItem
6162 \begin_layout Plain Layout
6168 , which is a standard class.
6172 \begin_layout Standard
6173 Start by copying the existing class's layout file into your local directory:
6177 \begin_layout Plain Layout
6178 Of course, which directory is your local directory will vary by platform,
6179 and LyX allows you to specify your local directory on startup, too, using
6181 \begin_inset Flex CharStyle:Code
6184 \begin_layout Plain Layout
6198 \begin_layout LyX-Code
6199 cp report.layout ~/.lyx/layouts/myclass.layout
6202 \begin_layout Standard
6204 \begin_inset Flex CharStyle:Code
6207 \begin_layout Plain Layout
6213 and change the line:
6216 \begin_layout LyX-Code
6219 DeclareLaTeXClass{report}
6222 \begin_layout Standard
6226 \begin_layout LyX-Code
6229 DeclareLaTeXClass[report, myclass.sty]{report (myclass)}

6255 Start LyX and select
6256 \begin_inset Flex CharStyle:MenuItem
6259 \begin_layout Plain Layout
6260 Tools\SpecialChar \menuseparator
6267 Then restart LyX and try creating a new document.
6269 \begin_inset Flex CharStyle:MenuItem

6283 Document\SpecialChar \menuseparator
6290 It is likely that some of the sectioning commands and such in your new
6291 class will work differently from how they worked in the base class—
6292 \begin_inset Flex CharStyle:Code
6295 \begin_layout Plain Layout
6301 in this example—so you can fiddle around with the settings for the different
6302 sections if you wish.
6303 The layout information for sections is contained in
6304 \begin_inset Flex CharStyle:Code
6307 \begin_layout Plain Layout
6313 , but you do not need to copy and change this file.
6314 Instead, you can simply add your changes to your layout file, after the
6316 \begin_inset Flex CharStyle:Code
6319 \begin_layout Plain Layout
6325 , which itself includes
6326 \begin_inset Flex CharStyle:Code
6329 \begin_layout Plain Layout
6336 For example, you might add these lines:
6339 \begin_layout LyX-Code
6343 \begin_layout LyX-Code
6347 \begin_layout LyX-Code
6351 \begin_layout LyX-Code
6355 \begin_layout LyX-Code
6359 \begin_layout Standard
6360 to change the font for chapter headings to sans-serif.
6361 This will override (or, in this case, add to) the existing declaration
6362 for the Chapter style.
6366 \begin_layout Standard
6367 Your new package may also provide commands or environments not present in
6369 In this case, you will want to add these to the layout file.
6371 \begin_inset CommandInset ref
6373 reference "sec:TextClass"
6377 for information on how to do so.
6380 \begin_layout Standard
6382 \begin_inset Flex CharStyle:MenuItem
6385 \begin_layout Plain Layout
6391 can be used with several different document classes, and even if it cannot,
6392 you might find it easiest just to write a module that you can load with
6394 The simplest possible such module would be:
6397 \begin_layout LyX-Code
6400 DeclareLyXModule{My Package}
6403 \begin_layout LyX-Code
6407 \begin_layout LyX-Code
6408 #Support for mypkg.sty.
6411 \begin_layout LyX-Code
6413 \begin_inset Newline newline
6419 \begin_layout LyX-Code
6421 \begin_inset Newline newline
6427 \begin_layout LyX-Code
6429 \begin_inset Newline newline
6435 \begin_inset Newline newline
6441 \begin_layout Standard
6442 A more complex module might modify the behavior of some existing constructs
6443 or define some new ones.
6445 \begin_inset CommandInset ref
6447 reference "sec:TextClass"
6454 \begin_layout Subsection
6456 \begin_inset Flex CharStyle:MenuItem
6459 \begin_layout Plain Layout
6468 \begin_layout Standard
6469 There are two possibilities here.
6470 One is that the class file is itself based upon an existing document class.
6471 For example, many thesis classes are based upon
6472 \begin_inset Flex CharStyle:MenuItem
6475 \begin_layout Plain Layout
6482 To see whether yours is, look for a line like
6485 \begin_layout LyX-Code
6491 \begin_layout Standard
6493 If so, then you may proceed largely as in the previous section, though
6495 \begin_inset Flex CharStyle:Code
6498 \begin_layout Plain Layout
6504 line will be different.
6505 If your new class is
6506 \begin_inset Flex CharStyle:Code
6509 \begin_layout Plain Layout
6515 and it is based upon
6516 \begin_inset Flex CharStyle:Code
6519 \begin_layout Plain Layout
6525 , then the line should read:
6529 \begin_layout Plain Layout
6530 And it will be easiest if you save the file to
6531 \begin_inset Flex CharStyle:Code
6534 \begin_layout Plain Layout
6540 : LyX assumes that the document class has the same name as the layout file.
6549 \begin_layout LyX-Code
6552 DeclareLaTeXClass[thesis,book]{thesis}
6555 \begin_layout Standard
6556 If, on the other hand, the new class is not based upon an existing class,
6557 you will probably have to
6558 \begin_inset Quotes eld
6562 \begin_inset Quotes erd
6566 We strongly suggest copying an existing layout file which uses a similar
6567 LaTeX class and then modifying it, if you can do so.
6568 At least use an existing file as a starting point so you can find out what
6569 items you need to worry about.
6570 Again, the specifics are covered below.
6573 \begin_layout Subsection
6575 \begin_inset CommandInset label
6577 name "sub:Creating-Templates"
6584 \begin_layout Standard
6585 Once you have written a layout file for a new document class, you might
6586 want to consider writing a
6591 A template acts as a kind of tutorial for your layout, showing how it might
6592 be used, though containing dummy content.
6593 You can of course look at the various templates included with LyX for ideas.
6596 \begin_layout Standard
6597 Templates are created just like usual documents: using LyX.
6598 The only difference is that usual documents contain all possible settings,
6599 including the font scheme and the paper size.
6600 Usually a user doesn't want a template to overwrite his preferred settings
6601 for such parameters.
6602 For that reason, the designer of a template should remove the corresponding
6604 \begin_inset Flex CharStyle:Code
6607 \begin_layout Plain Layout
6616 \begin_inset Flex CharStyle:Code
6619 \begin_layout Plain Layout
6627 from the template LyX file.
6628 This can be done with any simple text-editor, for example
6629 \begin_inset Flex CharStyle:Code
6632 \begin_layout Plain Layout
6639 \begin_inset Flex CharStyle:Code
6642 \begin_layout Plain Layout
6652 \begin_layout Standard
6653 Put the edited template files you create in
6654 \begin_inset Flex CharStyle:Code
6657 \begin_layout Plain Layout
6663 , copy the ones you use from the global template directory in
6664 \begin_inset Flex CharStyle:Code
6667 \begin_layout Plain Layout
6673 to the same place, and redefine the template path in the
6674 \begin_inset Flex CharStyle:MenuItem
6677 \begin_layout Plain Layout
6678 Tools\SpecialChar \menuseparator
6679 Preferences\SpecialChar \menuseparator
6688 \begin_layout Standard
6689 Note, by the way, that there is a template which has a particular meaning:
6691 \begin_inset Flex CharStyle:Code
6694 \begin_layout Plain Layout
6701 This template is loaded every time you create a new document with
6702 \begin_inset Flex CharStyle:MenuItem
6705 \begin_layout Plain Layout
6706 File\SpecialChar \menuseparator
6712 in order to provide useful defaults.
6713 To create this template from inside LyX, all you have to do is to open
6714 a document with the correct settings, and use the
6715 \begin_inset Flex CharStyle:MenuItem
6718 \begin_layout Plain Layout
6719 Save as Document Defaults
6727 \begin_layout Subsection
6728 Upgrading old layout files
6731 \begin_layout Standard
6732 The format of layout files changes with each LyX release, so old layout
6733 files need to be converted to the new format.
6734 This process has been automated since LyX 1.4: If LyX reads a layout file
6735 in an older format, it automatically calls the script
6736 \begin_inset Flex CharStyle:Code
6739 \begin_layout Plain Layout
6745 to convert it to a temporary file in current format.
6746 The original file is left untouched.
6747 If you use the layout file often, then, you may want to convert it permanently,
6748 so that LyX does not have to do so itself every time.
6749 To do this, you can call the converter manually:
6752 \begin_layout LyX-Code
6753 mv myclass.layout myclass.old
6756 \begin_layout LyX-Code
6757 python LyXDir/scripts/layout2layout.py myclass.old myclass.layout
6760 \begin_layout Standard
6762 \begin_inset Flex CharStyle:Code
6765 \begin_layout Plain Layout
6771 with the name of your LyX system directory, of course.
6774 \begin_layout Standard
6775 Note that manual conversion does not affect included files, so these will
6776 have to be converted separately.
6779 \begin_layout Section
6780 \begin_inset CommandInset label
6782 name "sec:TextClass"
6786 The layout file format
6789 \begin_layout Standard
6790 When it's finally time to get your hands dirty and create or edit your own
6791 layout file, the following sections describe what you're up against.
6792 Our advice is to go slowly, save and test often, listen to soothing music,
6793 and enjoy one or two of your favorite adult beverages; more if you are
6794 getting particularly stuck.
6795 It's really not that hard, except that the multitude of options can become
6796 overwhelming if you try to do too much in one sitting.
6797 Go have another adult beverage, just for good measure.

6888 \begin_layout Plain Layout
6895 There is one exception to this rule.
6897 \begin_inset Flex CharStyle:Code
6900 \begin_layout Plain Layout
6906 files should begin with a line like:

6915 \begin_layout LyX-Code
6920 DeclareLaTeXClass{article}
6923 \begin_layout Standard
6924 The second line is used when you (re)configure LyX.
6925 The layout file is read by the LaTeX script
6926 \begin_inset Flex CharStyle:Code
6929 \begin_layout Plain Layout
6935 , in a special mode where
6936 \begin_inset Flex CharStyle:Code
6939 \begin_layout Plain Layout
6946 The first line is just a LaTeX comment, and the second one contains the
6947 declaration of the text class.
6948 If these lines appear in a file named

6952 \begin_layout Plain Layout

6968 (the name of the layout file) which uses the LaTeX document class

7002 Let's assume that you wrote your own text class that uses the
7003 \begin_inset Flex CharStyle:Code
7006 \begin_layout Plain Layout
7012 document class, but where you changed the appearance of the section headings.
7013 If you put it in a file
7014 \begin_inset Flex CharStyle:Code
7017 \begin_layout Plain Layout
7023 , the header of this file should be:
7026 \begin_layout LyX-Code
7029 #% Do not delete the line below; configure depends on this
7032 \begin_layout LyX-Code
7037 DeclareLaTeXClass[article]{article (with my own headings)}
7040 \begin_layout Standard
7041 This declares a text class
7042 \begin_inset Flex CharStyle:Code
7045 \begin_layout Plain Layout
7051 , associated with the LaTeX document class
7052 \begin_inset Flex CharStyle:Code
7055 \begin_layout Plain Layout
7062 \begin_inset Quotes eld
7065 article (with my own headings)
7066 \begin_inset Quotes erd
7070 If your text class depends on several packages, you can declare it as:
7073 \begin_layout LyX-Code
7076 #% Do not delete the line below; configure depends on this
7079 \begin_layout LyX-Code
7084 DeclareLaTeXClass[article,foo.sty]{article (with my own headings)}
7087 \begin_layout Standard
7088 This indicates that your text class uses the
7089 \begin_inset Flex CharStyle:Code
7092 \begin_layout Plain Layout
7099 Finally, it is also possible to declare classes for DocBook code.
7100 Typical declarations will look like:
7103 \begin_layout LyX-Code
7106 #% Do not delete the line below; configure depends on this
7109 \begin_layout LyX-Code
7114 DeclareDocBookClass[article]{SGML (DocBook article)}
7117 \begin_layout Standard
7118 Note that these declarations can also be given an optional parameter declaring
7119 the name of the document class (but not a list).
7122 \begin_layout Standard
7123 So, to be as explicit as possible, the form of the layout declaration is:
7126 \begin_layout LyX-Code
7131 DeclareLaTeXClass[class,package.sty]{layout description}
7134 \begin_layout Standard
7135 The class need only be specified if the name of the LaTeX class file and
7136 the name of the layout file are different; if the name of the class file
7137 is not specified, then LyX will simply assume that it is the same as the
7138 name of the layout file.
7141 \begin_layout Standard
7142 When the text class has been modified to your taste, all you have to do
7143 is to copy it either to
7144 \begin_inset Flex CharStyle:Code

7168 Tools\SpecialChar \menuseparator
7174 , exit LyX and restart.
7175 Then your new text class should be available along with the others.
7178 \begin_layout Standard
7179 Once the layout file is installed, you can edit it and see your changes
7180 without having to reconfigure or to restart LyX.
7185 \begin_layout Plain Layout
7186 In versions of LyX prior to 1.6, this was not true.
7187 As a result, editing layout files was very time consuming, since you had
7188 constantly to restart LyX to see changes.
7193 You can force a reload of the current layout by using the LyX function
7195 \begin_inset Flex CharStyle:MenuItem
7198 \begin_layout Plain Layout
7205 There is no default binding for this function—though, of course, you can
7206 bind it to a key yourself.
7207 But you will normally use this function simply by entering it in the mini-buffe
7212 \begin_layout Standard
7218 \begin_inset Flex CharStyle:MenuItem
7221 \begin_layout Plain Layout
7227 is very much an `advanced feature'.
7232 recommended that you save your work before using this function.
7237 recommended that you not attempt to edit layout information while simultaneousl
7238 y working on a document that you care about.
7239 Use a test document.
7240 Syntax errors and the like in your layout file could cause peculiar behavior.
7241 In particular, such errors could cause LyX to regard the current layout
7242 as invalid and to attempt to switch to some other layout.
7246 \begin_layout Plain Layout
7247 Really bad syntax errors may even caused LyX to exit.
7248 This is because certain sorts of errors may make LyX unable to read
7258 The LyX team strives to keep LyX stable in such situations, but safe is
7263 \begin_layout Plain Layout
7264 While we're giving advice: make regular backups.
7265 And be nice to your mother.
7273 \begin_layout Subsection
7274 The Module Declaration
7277 \begin_layout Standard
7278 A module must begin with a line like the following:
7281 \begin_layout LyX-Code
7284 DeclareLyXModule[endnotes.sty]{Endnotes}
7287 \begin_layout Standard
7288 The mandatory argument, in curly brackets, is the name of the module, as
7290 \begin_inset Flex CharStyle:MenuItem
7293 \begin_layout Plain Layout

7301 The argument in square brackets is optional: It declares any LaTeX packages
7302 on which the module depends.
7303 Please note that only packages about which LyX knows should be listed in
7304 the square brackets.
7308 \begin_layout Plain Layout
7309 The list of such packages is documented only in the source code.
7314 LyX will not check for arbitrary packages.
7315 It is also possible to use the form
7316 \begin_inset Flex CharStyle:MenuItem
7319 \begin_layout Plain Layout
7325 as an optional argument, which declares that the module can only be used
7326 when there exists a conversion chain between the formats `

7337 \begin_inset Flex CharStyle:Code

7362 \begin_layout LyX-Code

7507 This tag was introduced with LyX 1.4.0.
7508 Layout files from LyX 1.3.x and earlier don't have an explicit file format
7509 and are considered to be of format 1.
7510 The format for the present version of LyX is format 21.
7511 But each version of LyX is capable of reading earlier versions' layout
7512 files, just as they are capable of reading files produced by earlier versions
7514 There is, however, no provision for converting to earlier formats.
7515 So LyX 1.6.x will not read layout files in format 21 but only files in format

15165 Tags for XHTML output
15168 \begin_layout Standard
15169 As with LaTeX or DocBook, the format of LyX's XHTML output is also controlled
15170 by layout information.
15171 In general, LyX provides sensible defaults and, as mentioned earlier, it
15172 will even construct default CSS style rules from the other layout tags.
15173 For example, LyX will attempt to use the information provided in the
15174 \begin_inset Flex CharStyle:Code
15177 \begin_layout Plain Layout
15183 declaration for the Chapter style to write CSS that will appropriately
15184 format chapter headings.
15187 \begin_layout Standard
15188 In many cases, then, you may not have to do anything at all to get acceptable
15189 XHTML output for your own environments, custom insets, and so forth.
15190 But in some cases you will, and so LyX provides a number of layout tags
15191 that can be used to customize the XHTML and CSS that are generated.
15194 \begin_layout Standard
15195 Note that there are two tags,
15196 \begin_inset Flex CharStyle:Code
15199 \begin_layout Plain Layout
15206 \begin_inset Flex CharStyle:Code
15209 \begin_layout Plain Layout

15227 \begin_inset CommandInset label
15229 name "sub:Paragraph-Style-XHTML"
15236 \begin_layout Standard
15237 The sort of XHTML LyX outputs for a paragraph depends upon whether we are
15238 dealing with a normal paragraph, a command, or an environment, where this
15239 is itself determined by the contents of the corresponding
15240 \begin_inset Flex CharStyle:Code
15243 \begin_layout Plain Layout
15253 \begin_layout Standard
15254 For a command or normal paragraph, the output XHTML has the following form:
15257 \begin_layout LyX-Code
15259 \begin_inset Quotes erd
15263 \begin_inset Quotes erd
15269 \begin_layout LyX-Code

15289 \begin_layout Standard
15290 The label tags are of course omitted if the paragraph does not have a label.
15293 \begin_layout Standard
15294 For an environment that is not some sort of list, the XHTML takes this form:
15297 \begin_layout LyX-Code

15338 Note that the label is output only for the first paragraph, as it should

15511 d by means of the layout tags we are about to describe.

16841 WARNING: This portion of the documentation has not been updated for some
16843 We certainly hope that it is still accurate, but there are no guarantees.
16851 \begin_layout Standard
16852 The use of material from sources external to LyX is covered in detail in
16858 This part of the manual covers what needs to happen behind the scenes for
16859 new sorts of material to be included.
16862 \begin_layout Section
16866 \begin_layout Standard
16867 The external material feature is based on the concept of a
16872 A template is a specification of how LyX should interface with a certain
16874 As bundled, LyX comes with predefined templates for Xfig figures, various
16875 raster format images, chess diagrams, and LilyPond music notation.
16876 You can check the actual list by using the menu
16877 \begin_inset Flex CharStyle:MenuItem
16880 \begin_layout Plain Layout
16881 Insert\SpecialChar \menuseparator
16882 File\SpecialChar \menuseparator
16889 Furthermore, it is possible to roll your own template to support a specific
16891 Later we'll describe in more detail what is involved, and hopefully you
16892 will submit all the templates you create so we can include them in a later
16896 \begin_layout Standard
16897 Another basic idea of the external material feature is to distinguish between
16898 the original file that serves as a base for final material and the produced
16899 file that is included in your exported or printed document.
16900 For example, consider the case of a figure produced with
16901 \begin_inset Flex CharStyle:Code
16904 \begin_layout Plain Layout
16911 The Xfig application itself works on an original file with the
16912 \begin_inset Flex CharStyle:Code
16915 \begin_layout Plain Layout
16922 Within Xfig, you create and change your figure, and when you are done,
16924 \begin_inset Flex CharStyle:Code
16927 \begin_layout Plain Layout
16934 When you want to include the figure in your document, you invoke
16935 \begin_inset Flex CharStyle:Code
16938 \begin_layout Plain Layout
16944 in order to create a PostScript file that can readily be included in your
16947 \begin_inset Flex CharStyle:Code
16950 \begin_layout Plain Layout
16956 file is the original file, and the PostScript file is the produced file.
16959 \begin_layout Standard
16960 This distinction is important in order to allow updating of the material
16961 while you are in the process of writing the document.
16962 Furthermore, it provides us with the flexibility that is needed to support
16963 multiple export formats.
16964 For instance, in the case of a plain text file, it is not exactly an award-winn
16965 ing idea to include the figure as raw PostScript.
16966 Instead, you'd either prefer to just include a reference to the figure
16967 or try to invoke some graphics to ASCII converter to make the final result
16968 look similar to the real graphics.
16969 The external material management allows you to do this, because it is parametri
16970 zed on the different export formats that LyX supports.
16973 \begin_layout Standard
16974 Besides supporting the production of different products according to the
16975 exported format, it supports tight integration with editing and viewing
16977 In the case of an Xfig figure, you are able to invoke Xfig on the original
16978 file with a single click from within the external material dialog in LyX,
16979 and also preview the produced PostScript file with Ghostview with another
16981 No more fiddling around with the command line and/or file browsers to locate
16982 and manipulate the original or produced files.
16983 In this way, you are finally able to take full advantage of the many different
16984 applications that are relevant to use when you write your documents, and
16985 ultimately be more productive.
16988 \begin_layout Section

16992 \begin_layout Standard
16993 It is relatively easy to add custom external template definitions to LyX.
16994 However, be aware that doing this in an careless manner most probably
16998 introduce an easily exploitable security hole.

18029 The substitution mechanism
18032 \begin_layout Standard
18033 When the external material facility invokes an external program, it is done
18034 on the basis of a command defined in the template configuration file.
18035 These commands can contain various macros that are expanded before execution.
18036 Execution always take place in the directory of the containing document.
18039 \begin_layout Standard
18040 Also, whenever external material is to be displayed, the name will be produced
18041 by the substitution mechanism, and most other commands in the template
18042 definition support substitution as well.
18045 \begin_layout Standard
18046 The available macros are the following:

18436 \begin_layout Standard
18437 You may ask why there are so many path macros.
18438 There are mainly two reasons:
18441 \begin_layout Enumerate
18442 Relative and absolute file names should remain relative or absolute, respectivel
18444 Users may have reasons to prefer either form.
18445 Relative names are useful for portable documents that should work on different
18446 machines, for example.
18447 Absolute names may be required by some programs.
18450 \begin_layout Enumerate
18451 LaTeX treats relative file names differently than LyX and other programs
18452 in nested included files.
18453 For LyX, a relative file name is always relative to the document that contains
18455 For LaTeX, it is always relative to the master document.
18456 These two definitions are identical if you have only one document, but
18457 differ if you have a master document that includes part documents.
18458 That means that relative filenames must be transformed when presented to
18460 Fortunately LyX does this automatically for you if you choose the right
18464 \begin_layout Standard
18465 So which path macro should be used in new template definitions? The rule
18469 \begin_layout Itemize
18471 \begin_inset Flex CharStyle:Code
18474 \begin_layout Plain Layout
18480 if an absolute path is required.
18483 \begin_layout Itemize
18485 \begin_inset Flex CharStyle:Code
18488 \begin_layout Plain Layout
18489 $$AbsOrRelPathMaster
18494 if the substituted string is some kind of LaTeX input.
18497 \begin_layout Itemize
18499 \begin_inset Flex CharStyle:Code
18502 \begin_layout Plain Layout
18503 $$AbsOrRelPathParent
18508 in order to preserve the user's choice.
18511 \begin_layout Standard
18512 There are special cases where this rule does not work and e.
18513 \begin_inset space \thinspace{}
18517 \begin_inset space \space{}
18520 relative names are needed, but normally it will work just fine.
18521 One example for such a case is the command
18522 \begin_inset Flex CharStyle:Code
18525 \begin_layout Plain Layout
18526 ReferencedFile latex "$$AbsOrRelPathMaster$$Basename.pstex_t"
18531 in the XFig template above: We can't use the absolute name because the
18533 \begin_inset Flex CharStyle:Code
18536 \begin_layout Plain Layout
18542 files needs the relative name in order to rewrite the file content.

18546 Security discussion
18547 \begin_inset CommandInset label
18549 name "sec:Security-discussion"
18556 \begin_layout Standard
18557 The external material feature interfaces with a lot of external programs
18558 and does so automatically, so we have to consider the security implications
18560 In particular, since you have the option of including your own filenames
18561 and/or parameter strings and those are expanded into a command, it seems
18562 that it would be possible to create a malicious document which executes
18563 arbitrary commands when a user views or prints the document.
18564 This is something we definitely want to avoid.
18567 \begin_layout Standard
18568 However, since the external program commands are specified in the template
18569 configuration file only, there are no security issues if LyX is properly
18570 configured with safe templates only.
18571 This is so because the external programs are invoked with the
18572 \begin_inset Flex CharStyle:Code
18575 \begin_layout Plain Layout
18581 -system call rather than the
18582 \begin_inset Flex CharStyle:Code
18585 \begin_layout Plain Layout
18591 system-call, so it's not possible to execute arbitrary commands from the
18592 filename or parameter section via the shell.
18595 \begin_layout Standard
18596 This also implies that you are restricted in what command strings you can
18597 use in the external material templates.
18598 In particular, pipes and redirection are not readily available.
18599 This has to be so if LyX should remain safe.
18600 If you want to use some of the shell features, you should write a safe
18601 script to do this in a controlled manner, and then invoke the script from
18602 the command string.
18606 \begin_layout Standard
18607 It is possible to design a template that interacts directly with the shell,
18608 but since this would allow a malicious user to execute arbitrary commands
18609 by writing clever filenames and/or parameters, we generally recommend that
18610 you only use safe scripts that work with the
18611 \begin_inset Flex CharStyle:Code
18614 \begin_layout Plain Layout
18620 system call in a controlled manner.
18621 Of course, for use in a controlled environment, it can be tempting to just
18622 fall back to use ordinary shell scripts.
18623 If you do so, be aware that you
18627 provide an easily exploitable security hole in your system.
18628 Of course it stands to reason that such unsafe templates will never be
18629 included in the standard LyX distribution, although we do encourage people
18630 to submit new templates in the open source tradition.
18631 But LyX as shipped from the official distribution channels will never have
18635 \begin_layout Standard
18636 Including external material provides a lot of power, and you have to be
18637 careful not to introduce security hazards with this power.
18638 A subtle error in a single line in an innocent looking script can open
18639 the door to huge security problems.
18640 So if you do not fully understand the issues, we recommend that you consult
18641 a knowledgeable security professional or the LyX development team if you
18642 have any questions about whether a given template is safe or not.
18643 And do this before you use it in an uncontrolled environment.
