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_inset CommandInset label

\end_inset
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
\begin_inset Flex CharStyle:MenuItem

\begin_layout PlainLayout

H
\bar default
elp\SpecialChar \menuseparator
About
\begin_inset Space ~
\end_inset
Ly
\bar under
X
\end_layout
\end_inset
.
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
LyXDir
\end_layout
\end_inset
and the latter
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
UserDir
\end_layout
\end_inset
in the remainder of this document.

\end_layout
\begin_layout Standard
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
LyXDir
\end_layout
\end_inset
and its sub-directories contain a number of files and that can be used
to customise LyX's behaviour.
You can change many of these files from within LyX itself through the
\begin_inset Flex CharStyle:MenuItem

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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
LyXDir
\end_layout
\end_inset
.
These files fall in different categories, described in the following subsection

\begin_layout Standard
The files, which are to be found in
\begin_inset Flex CharStyle:MenuItem

, are generated when you configure LyX.
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
en at any time.

This directory is used as a mirror of
\begin_inset Flex CharStyle:Code

\end_inset
, which means that every file in
\begin_inset Flex CharStyle:Code

Any configuration file described in the above sections can be placed either

\bar under

, LyX runs the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
configure.py
\end_layout
\end_inset
script, and the resulting files are written in your local configuration
directory.
This means that any additional text class file that you might have added
in
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
UserDir/layouts
\end_layout
\end_inset
will be added to the list of classes in the

copy the files in
\begin_inset Flex CharStyle:Code

\begin_inset Flex CharStyle:MenuItem

menu will open them!
\end_layout
\begin_layout Section
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.
\end_layout
\begin_layout Standard
Invoking LyX with the command line switch
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
-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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
-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
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
LYX_USERDIR_15x
\end_layout
\end_inset
to some value has exactly the same effect.
\end_layout
\begin_layout Standard
Having several configurations also requires more maintenance: if you want
to add a new layout to
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
doc/
\end_layout
\end_inset
subirectory, however, since it contains a file written by the configuration
script (also accessible through
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
\bar under
T
\bar default
ools\SpecialChar \menuseparator
\bar under
R

\end_layout

) which is configuration-specific.

Screen fonts
\end_layout
\begin_layout Standard
The font used to display your documents on the LyX screen is very important,
since you'll be reading all your documents with this font.
Therefore it is important that the font be as readable and good-looking
as possible.
The LyX team tried to provide the best possible default font for you, but
since systems can be so different, it's quite possible that the default
fonts will be sub-optimal on your system.
Fortunately, you can do something about this.
Before we explain how, you should learn a bit more about fonts so that
you are better prepared for choosing your fonts.
There are trade-offs that are specific to your preferences and the capabilities
of your system.
\end_layout
\begin_layout Standard
Notice that this section only deals with the fonts on the
\emph on
screen
\emph default
inside the LyX window.
The fonts that appear on the
\emph on
paper
\emph default
\emph on
output
\emph default
are independent from these fonts, and are determined by the document class.
Read the
\emph on
User's Guide
\emph default
to learn how to change the font of the printed version of your document.
\end_layout
\begin_layout Standard
Basically, screen fonts come in two different kinds: scalable outline fonts
and non-scalable bitmap fonts.
This distinction seems a bit arbitrary, since non-scalable fonts are actually
scalable in most modern font renderers.
The difference lies in the
\emph on
quality
\emph default
of the scaling and the
\emph on
speed
\emph default
of display.
The most important decision is thus whether you should use non-scalable
bitmap fonts or scalable outline fonts.
\end_layout
\begin_layout Standard
The scalable fonts are built from
\emph on
outlines
\emph default
of the single glyphs (i.e.
characters) in the font.
This means that each glyph is defined using mathematical curves that are
well suited for scaling to any requested size.
This mathematical definition is interpreted by the font renderer and turned
into a small picture composed of pixels according to which size and glyph
(or symbol) the programmer requests.
This means that scalable fonts will look pretty good in most sizes.Since
scalable fonts are defined in an abstract way, it can be hard to provide
a good rendering at small sizes, where each pixel has to be very carefully
computed to provide a good image.
Technically it is possible to do this from the mathematical definition,
but in order to keep the rendering reasonably fast, tradeoffs have to be
made, and the result is that scalable fonts can be difficult to read at
small sizes.
\end_layout
\begin_layout Standard
Bitmap fonts on the other hand, are defined by bitmap graphics from the
start, so they will look good at all the sizes they are meant for.
However, they don't scale well, because in order to scale a glyph, each
pixel is enlarged into several pixels.
It is the same effect that happens if you try to enlarge a picture in an
image manipulation program.
In order to relieve this effect, bitmap fonts are typically provided in
several fixed sizes typically from around 8 pixels high up to 34 pixels
or so high in steps according to what is believed to be useful.
The advantage of bitmap fonts is that no complicated computations are necessary
to display each glyph, so bitmap fonts are thus faster displayed than scalable
fonts.
The disadvantage is that sizes that don't exists as fixed versions have
to be scaled by doubling pixels, and thus look bad.
\end_layout
\begin_layout Standard
The net result of all this is that bitmap fonts are generally best for the
small sizes, where they are available, while scalable fonts are generally
best for large sizes.
The logical conclusion would thus be to use bitmap fonts for the small
sizes, and scalable fonts for the large sizes.
Unfortunately, this is not a good idea, since bitmap fonts and scalable
fonts are not designed to be used together, so the overall look of such
a scheme would be bad.
The best you can do is thus to try both schemes and decide for yourself
what suits you.
\end_layout
\begin_layout Standard
In the following, we will describe what to do if the text does not look
good in LyX.
We'll start with the most important parameters: DPI and font zoom.
\end_layout
\begin_layout Subsubsection
DPI setting and Font Zoom
\end_layout
\begin_layout Standard
LyX automatically tries to scale the fonts to look as close as the paper
output size as possible, except for the so-called font zoom factor.
\end_layout
\begin_layout Standard
In order for this to work on all systems, it relies on the screen DPI (dots
per inch) setting to be correct.
The DPI setting for your system is autodetected by LyX using information
provided by your system.
You can check what LyX autodetects the DPI setting to, by running LyX as
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
lyx -dbg 2
\end_layout
\end_inset
.
\end_layout
\begin_layout Standard
On many systems, this will not be correct, so you should check that it is
correct by hand.
On X11 systems, you can run
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
xdpyinfo | more
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
and write down what the DPI is for the resolution you use (this will be
close to the value LyX detects).
It is the number mentioned as
\begin_inset Quotes eld
\end_inset
resolution
\begin_inset Quotes erd
\end_inset
.
Also write down the number of pixels you have in the width (the first number
under
\begin_inset Quotes eld
\end_inset
dimensions
\begin_inset Quotes erd
\end_inset
).
\end_layout
\begin_layout Standard
Then get the good old ruler out of the closet, and measure the width of
the visible screen-image on your monitor.
Convert this measurement to inches if you used a centimeter ruler by dividing
by 2.54.
Now you can determine the correct DPI setting for your screen by dividing
the number of pixels in the width by the width of the screen-image on the
monitor.
If this number is more than, say, 5 DPI from the detected value, you should
either fix your system setup, or at least tell LyX that the DPI is different
than the detected value.
\end_layout
\begin_layout Standard
If you can't fix system setup (which of course is best since other programs
than LyX will benefit from this as well), you can tell LyX the correct
DPI using the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Preferences
\end_layout
\end_inset
dialog.
\end_layout
\begin_layout Standard
If the text is too small or too big for your taste, you should fiddle with
the font zoom setting.
This setting is used to scale the point size of the text.
If your DPI setting is correct, and the font zoom setting is set to 100,
this means that LyX will try to display the text exactly the same size
as it will appear on the paper-output.
If you set the zoom factor to 200, the text will try to be 2 times as big
as on paper.
Of course, this will only happen if LyX can find a font that has the appropriat
e size, which you can't count on.
Since LyX is a WYSIWYM system anyways, this limitation isn't much of an
issue.
\end_layout
\begin_layout Standard
The default font zoom setting is 150, since a monitor is typically wider
than a piece of paper, but you should try to fiddle with it through the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Font
\begin_inset Space ~

\end_layout
\end_inset
setting in the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Preferences
\end_layout
\end_inset
dialog to find a size that you like.
When you've found a setting that seems to work nicely for you (tip: use
the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
\bar under
A
\bar default
pply
\end_layout
\end_inset
button to keep the dialog open while you experiment), you can make this
setting the default by using the
\begin_inset Flex CharStyle:MenuItem

\begin_layout PlainLayout

\end_layout
\end_inset
button.
\end_layout
\begin_layout Standard
While it is often possible to find a suitable size for the text on the screen,
this doesn't necessarily mean that the fonts are the best ones available
on your system.
In order to help you get the most out of your system, you can use the font
definition commands to fine-tune the look of the text in greater detail
than merely size.
\end_layout
\begin_layout Subsubsection
Font definition commands
\end_layout
\begin_layout Standard
You can change LyX's screen fonts from within the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Preferences
\end_layout
\end_inset
dialog.
The number of fonts that are available on different systems vary.
\end_layout
\begin_layout Standard
Before you go about scrapping a bitmap font because the larger sizes look
\begin_inset Quotes eld
\end_inset
blocky
\begin_inset Quotes erd
\end_inset
, you should toggle the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
Use scalable fonts
\end_layout
\end_inset
button.
This is only useful if you use bitmap fonts, because only these don't scale
well.
If you define this flag, LyX will only use the fixed font sizes that are
available, and this guarantees that all bitmap fonts look good.
However, the downside is that there will be a greater difference between
the size of the fonts on screen and the size of fonts on paper because
LyX will have to be satisfied with the closest available size, and not
try to scale a size to fit.
Also, you can risk that some logically different sizes, such as
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Large
\end_layout
\end_inset
and
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Larger
\end_layout
\end_inset
, will be mapped to the same screen font, making it hard for you to see
the difference on screen.
\end_layout
\begin_layout Standard
One final note regarding the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
Use scalable fonts
\end_layout
\end_inset
flag: you should know that there is nothing wrong with using bitmap and
scalable fonts at the same time for different purposes.
For instance, it's common to use the scalable
\begin_inset Quotes eld
\end_inset
Utopia
\begin_inset Quotes erd
\end_inset
for the serif text together with a bitmap version of
\begin_inset Quotes eld
\end_inset
Helvetica
\begin_inset Quotes erd
\end_inset
.
And you can safely select the
\begin_inset Quotes eld
\end_inset
Use scalable fonts
\begin_inset Quotes erd
\end_inset
button without worries: It will only apply to the Helvetica font.
\end_layout
\begin_layout Standard
Sometimes the artifacts introduced by use of the flag can be relieved by
using the fine-detail screen font sizes which defines which point sizes
the different logical font sizes correspond to.
Run LyX as
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
lyx -dbg 513
\end_layout
\end_inset
to see exactly what concrete fonts the logical sizes map to, and try adjusting
the corresponding entries in the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Preferences
\end_layout
\end_inset
dialog until you've managed to hit the nail and get the fonts you want.
This can be hard to do, because LyX uses the DPI setting and the font zoom
settings to calculate which exact screen font size to ask the X server
for, thus obfuscating the mapping.
If you can't make it by trial-and-error, you can make the process more
transparent if you set both the DPI setting and font zoom settings to 100---eve
n when this is known to be wrong.
This will of course make your scalable fonts look weird, so use with care.
\end_layout
\begin_layout Standard

\begin_layout Subsubsection
Font encoding
\end_layout
\begin_layout Standard
By default, LyX will use fonts meant to write Western European text, including
all kinds of English.
This is defined through the so-called
\emph on
font
\emph default
\emph on
encoding
\emph default
.
If you want to use LyX to write for instance Eastern European text, Cyrillic
or any other language not covered by the ISO-8859-1 font encoding, you
can define a different one with the encoding setting.
This requires you to have special fonts installed.
You can use
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
xfontsel
\end_layout
\end_inset
to see whether this is the case: check the
\begin_inset Quotes eld
\end_inset
rgstry
\begin_inset Quotes erd
\end_inset
and
\begin_inset Quotes eld
\end_inset
encdng
\begin_inset Quotes erd
\end_inset
fields for ISO-8859-X values different from ISO-8859-1, and search for
one that contains the national characters of your language.
If you find any, enter this encoding in the dialog.
If not, go searching the Web for appropriate fonts.
For the Qt frontend, it's recommended you use an iso646 font set.
\end_layout
\begin_layout Standard
When you've set LyX up to use a different font encoding, you should also
consider changing the font used by dialog windows in LyX.
For instance, the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Table
\begin_inset Space ~
\end_inset
of
\begin_inset Space ~
\end_inset
Contents
\end_layout
\end_inset
dialog will not be understandable unless you tell LyX to use a different
font for this.
By default the menu font is set to
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
-*-helvetica-medium-r
\end_layout
\end_inset
, but often Helvetica is not available in the font encoding you need, so
the dialog allows this to be changed.
\end_layout
\begin_layout Standard
As you can see, there are quite a few options that can be used to fine tune
the look of your fonts.
This should not scare you from fiddling with the settings, because after
all, you will hopefully be using LyX for many hours in the future.
And contrary to real WYSIWYG word processors where you are tied to using
fonts that have to look good both on paper and on screen, LyX gives you
the possibility of using fonts that are designed to look good on the screen
while using a different set of fonts to look good on paper.

\end_layout
\begin_layout Standard
The option
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Vector graphics format
\end_layout
\end_inset
tells LyX that a format can contain vector graphics.
This information is used to determine the target format of included graphics
for
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
pdflatex
\end_layout
\end_inset
export.
Included graphics may need to be converted to either
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
pdf
\end_layout
\end_inset
,
\begin_inset Flex CharStyle:MenuItem
status collapsed

\begin_inset Flex CharStyle:MenuItem

\begin_layout Subsection
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 PlainLayout
For example, the file may refer to other files---images, for example---using
relative filenames, 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
\begin_layout List
\labelwidthstring 00.00.0000
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
$$s
\end_layout
\end_inset
The LyX system directory (e.

\begin_layout PlainLayout
$$l
\end_layout
\end_inset
The `LaTeX name'
\end_layout
\begin_layout Standard
The latter is to be given in a form suitable for inclusion in a LaTeX's
\series bold
\backslash
include
\series default
command and is relevant only when exporting files suitable for such inclusion.
\end_layout
\begin_layout Standard
Copiers can be used to do almost anything with output files.
For example, suppose you want generated pdf files to be copied to a special
directory,
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
/home/you/pdf/
\end_layout
\end_inset
.
Then you could write a shell script such as this one:
\end_layout
\begin_layout Standard
\begin_inset listings
inline false
status open
\begin_layout PlainLayout
#!/bin/bash
\end_layout
\begin_layout PlainLayout
FROMFILE=$1
\end_layout
\begin_layout PlainLayout
TOFILE=`basename $2`
\end_layout
\begin_layout PlainLayout
cp $FROMFILE /home/you/pdf/$TOFILE
\end_layout
\end_inset
Save that in your local LyX directory---say,
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
/home/you/.lyx/scripts/pdfcopier.sh
\end_layout
\end_inset
---and make it executable, if you need to do so on your platform.
Then, in the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Tools\SpecialChar \menuseparator
Preferences:Copiers
\end_layout
\end_inset
dialog, select the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
PDF(pdflatex)
\end_layout
\end_inset
format---or one of the other pdf formats---and enter
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
pdfcopier.sh $$i $$o
\end_layout
\end_inset
into the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Copier
\end_layout
\end_inset
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
install copiers for the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
HTML
\end_layout
\end_inset
and
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
HTML
\begin_inset Space ~
\end_inset
(MS Word)
\end_layout
\end_inset
formats.
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.
\begin_inset Foot
status collapsed
\begin_layout PlainLayout
This copier can be customized.
The optional
\begin_inset Quotes eld
\end_inset
-e
\begin_inset Quotes erd
\end_inset
argument takes a comma-separated list of extensions to be copied; if it
is omitted, all files will be copied.
The
\begin_inset Quotes eld
\end_inset
-t
\begin_inset Quotes erd
\end_inset
argument determines the extension added to the generated directory.
By default, it is
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout

\end_layout
\begin_layout Standard
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 between all the 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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
pdflatex
\end_layout
\end_inset
; via (DVI and) PostScript®, using
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
ps2pdf
\end_layout
\end_inset
; or via DVI, using
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
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 "sub:Formats"
\end_inset
.
For example, in the standard configuration, the formats named
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
pdf
\end_layout
\end_inset
,
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
pdf2
\end_layout
\end_inset
, and
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
pdf3
\end_layout
\end_inset
are defined, all of which share the extension
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
.pdf
\end_layout
\end_inset
, and which correspond to the conversion methods just mentioned.

For Linux, the manual page for

\end_layout
\end_inset
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.

LyX uses the GNU

status collapsed
\begin_layout PlainLayout
gettext
\end_layout
\end_inset
library to handle the internationalization of the interface.
To have LyX speak your favorite language in all menus and dialogs, you
need a
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
po
\end_layout
\end_inset
-file for that language.
When this is available, you'll have to generate a
\begin_inset Flex CharStyle:Code

\end_layout
\end_inset
-file from it and install the
\begin_inset Flex CharStyle:Code

The process of doing all of this is explained in the documentation for
GNU

It is possible to do this just for yourself, but if you're going to do
it, you might as well share the results of your labors with the rest of
the LyX community.
Send a message to the LyX developers' list for more information about how

\end_layout
\end_inset
For some menu- and widget-labels, there are also shortcut keys that should

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
Ambigous 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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
gettext
\end_layout
\end_inset
does not handle such ambigous translations.
Therefore you have to add some context information to the message: Instead
of
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
To
\end_layout
\end_inset
it becomes
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
To[[as in 'From format x to format y']]
\end_layout
\end_inset
and
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
To[[as in 'From page x to page y']].
\end_layout
\end_inset
Now the two occurences of
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
To
\end_layout
\end_inset
are different for
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
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.

\begin_layout PlainLayout
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
LyXDir/doc/xx_DocName.lyx
\end_layout
\end_inset
, where
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
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
Read
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
DocStyle.lyx
\end_layout
\end_inset
, the guide to writing LyX documentation.
Pay special attention to the translator's section.
\end_layout
\begin_layout Itemize
Check out the documentation translation web page at
\begin_inset CommandInset href
LatexCommand href
name "http://www.devel.lyx.org"
target "http://www.devel.lyx.org"
\end_inset
.
That way, you can find out which (if any) documents have already been translate
d into your language.
You can also find out who (if anyone) is organizing the effort to translate
the documentation into your language.
If no one is organizing the effort, please let us know that you're interested.

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

), 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.

\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 CharStyle:Code

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

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

\end_layout
\end_inset

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

If LyX cannot find a mapping for the string produced by the keystroke or
a deadkey sequence, it will check if it looks like an accented char and
try to draw an accent over the character on screen.
\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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
^
\end_layout
\end_inset
-key [a.k.a.
\begin_inset Space ~
\end_inset
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Shift-6
\end_layout
\end_inset
] to the LyX command
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
accent-circumflex
\end_layout
\end_inset
in your
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
lyxrc
\end_layout
\end_inset
file.
Now, whenever you type the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
^
\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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
^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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
^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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
t
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
never takes a circumflex accent.
Hitting
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
,-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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Meta-
\end_layout
\end_inset
,
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Ctrl-
\end_layout
\end_inset
, and
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Shift-
\end_layout
\end_inset
in combination with an accent, like
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
~
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
or
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
,
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
or
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
^
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
.
Another way involves using
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
xmodmap
\end_layout
\end_inset
and
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
xkeycaps
\end_layout
\end_inset
to set up the special
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
Mode_Switch
\end_layout
\end_inset
key.
The
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
Mode_Switch
\end_layout
\end_inset
acts in some ways just like
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
usldead_cedilla
\end_layout
\end_inset
and then binding this symbolic key to the corresponding LyX command.

Installing New Document Classes
\end_layout
\end_inset
\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.
Some definitions: a document class is a LaTeX file (usually ending in
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.cls
\end_layout
\end_inset
or
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.sty
\end_layout
\end_inset
) that describes the format of a document such as an article, report, journal
preprint, etc, and all the commands needed to realize that format.
A layout file is a LyX file that corresponds to a LaTeX document class
and that tells LyX how to
\begin_inset Quotes eld
\end_inset
draw
\begin_inset Quotes erd
\end_inset
things on the screen to make the display look something like the final
printed page.
More precisely, a layout file describes a
\begin_inset Quotes eld
\end_inset
text class
\begin_inset Quotes erd
\end_inset
which is the internal construct LyX uses to render the screen display.
\begin_inset Quotes eld
\end_inset
Layout
\begin_inset Quotes erd
\end_inset
and
\begin_inset Quotes eld
\end_inset
text class
\begin_inset Quotes erd
\end_inset
can be used somewhat interchangeably, but it is better to refer to the
file as the layout, and the thing living in LyX's memory as the text class.
A template file is simply a LyX document that contains a set of predefined
entries for a given document class---entries that are generally required
for that class.
Templates are especially useful for things like journal manuscripts that
are to be submitted electronically.

\begin_layout Section
Installing a new LaTeX package
\end_layout
\begin_layout Standard
Some installations may not include a LaTeX package that you would like to
use within LyX.
For example, you might need FoilTeX, a common (and very powerful) package
for preparing slides or viewgraphs for overhead projectors.
On some systems, you may have a GUI for installing such packages: MikTeX
on Windows®, for example.
\end_layout
\begin_layout Standard
If you don't have such a GUI, then you can follow these steps.
\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
You can install this package in several different places.
If you want it to be available for all users on your system, then you should
install it in your `local' TeX tree; if you want (or need) it to be available
just for you, then you can install it in your own `user' TeX tree.
Where these should be created, if they do not already exist, depends upon
the details of your system.
To find out, look in the file
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
texmf.cnf
\end_layout
\end_inset
.
\begin_inset Foot
status collapsed
\begin_layout PlainLayout
This usually lives in the directory
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
$TEXMF/web2c
\end_layout
\end_inset
, though you can run
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
kpsewhich texmf.cnf
\end_layout
\end_inset
to locate it.
\end_layout
\end_inset
The location of the `local' TeX tree is defined by
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
TEXMFLOCAL
\end_layout
\end_inset
; this is usually somewhere like
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
/usr/local/share/texmf/
\end_layout
\end_inset
.
The `user' TeX tree is defined by
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
TEXMFHOME
\end_layout
\end_inset
and is commonly at
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
$HOME/texmf/
\end_layout
\end_inset
.
(If these variables are not predefined, you can define them.) You'll probably
need root permissions to create or modify the `local' tree; but your `user'
tree shouldn't have such limitations.
\end_layout
\begin_layout Enumerate
Make sure
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
TEXMF
\end_layout
\end_inset
includes the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
TEXMFLOCAL
\end_layout
\end_inset
and
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
TEXMFHOME
\end_layout
\end_inset
variables; e.g.
\newline
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
TEXMF = {$TEXMFHOME,!!$TEXMFLOCAL,!!$TEXMFMAIN}
\end_layout
\end_inset
\newline
But, again, most of this will
\begin_inset Quotes eld
\end_inset
just work
\begin_inset Quotes erd
\end_inset
.
\end_layout
\begin_layout Enumerate
Create your local
\begin_inset Foot

\begin_layout PlainLayout
We'll assume henceforth that you're defining `local' TeX tree.
If you're defining a user tree, just adjust as necessary.
\end_layout
\end_inset
TeX tree.
You must follow the directory structure of your existing
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
texmf
\end_layout
\end_inset
directory, which will be found at
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
TEXMFMAIN
\end_layout
\end_inset
.
For example, latex packages should go under
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
$TEXMFLOCAL/tex/latex/
\end_layout
\end_inset
.
\end_layout
\begin_layout Enumerate
Install the package.
For example, you would unpack the FoilTeX tarball and copy it to
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
$TEXMFLOCAL/tex/latex/foiltex
\end_layout
\end_inset
.
The
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
foiltex
\end_layout
\end_inset
directory contains various files.
\end_layout
\begin_layout Enumerate
Run:
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
texhash
\end_layout
\end_inset
.
This should create
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
$TEXMFLOCAL/ls-R
\end_layout
\end_inset
amongst others.
\end_layout
\begin_layout Standard
Your package is now installed and available to LaTeX.
To make it available to LyX, you need to create a Layout file, if one is
not already available.
(See the next section.) Once you have a layout file, you need only reconfigure

layout design who are willing to share what they've learned.)
\end_layout
\begin_layout Standard
As you prepare to write a new layout, it is extremely helpful to look at
the example layouts distributed with LyX.
If you use a nice LaTeX document class that might be of interest for others,

Layout modules
\end_layout
\begin_layout Standard
Similar to layout files, and new with LyX 1.6, are layout
\emph on
modules
\emph default
.
Modules are to LaTeX packages much as layouts are to LaTeX classes, and
some modules---such as the Endnotes module---provide support for just such
a package.
In a sense, layout modules are similar to included files---files like
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
stdsections.inc
\end_layout
\end_inset
---in that modules are not specific to a given document layout but may be
used with many different layouts.
The difference is that using a layout module does not require editing the
layout file.
Rather, modules are selected in the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
\bar under
D
\bar default
ocument\SpecialChar \menuseparator
\bar under
S
\bar default
ettings
\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 or flex inset.
But modules may, in principle, contain anything a layout file can contain.
\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 argument in square brackets is optional: It declares any LaTeX packages
on which the module depends.
The mandatory argument, in curly brackets, is the name of the module, as
it should appear in
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Document\SpecialChar \menuseparator
Settings
\end_layout
\end_inset
.
\end_layout
\begin_layout Standard
The module declaration should then be followed by lines like the following:
\end_layout
\begin_layout LyX-Code
#DescriptionBegin
\end_layout
\begin_layout LyX-Code
#Adds an endnote command, in addition to footnotes.
\end_layout
\begin_layout LyX-Code
#You will need to add
\backslash
theendnotes in ERT where you
\end_layout
\begin_layout LyX-Code
#want the endnotes to appear.
\end_layout
\begin_layout LyX-Code
#DescriptionEnd
\end_layout
\begin_layout LyX-Code
#Requires: somemodule | othermodule
\end_layout
\begin_layout LyX-Code
#Excludes: badmodule
\end_layout
\begin_layout Standard
The description is used in
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Document\SpecialChar \menuseparator
Settings
\end_layout
\end_inset
to provide the user with information about what the module does.
The
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
Requires
\end_layout
\end_inset
line is used to identify other modules with which this one must be used;
the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
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
\emph on
filenames
\emph default
without the .module extension.
So
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
somemodule
\end_layout
\end_inset
is really
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
somemodule.module
\end_layout
\end_inset
.
\end_layout
\begin_layout Standard
After creating a new module, 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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
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 so
\emph default
.
In fact,
\emph on
it is strongly recommended that you not attempt to edit modules while simultaneo
usly working on 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.

Supporting new document classes

There are two situations you are likely to encounter when wanting to support
a new LaTeX document class, involving LaTeX2e class (
\begin_inset Flex CharStyle:Code

\end_layout
\end_inset
) and style (
\begin_inset Flex CharStyle:Code

Supporting a style file is usually fairly easy.
Supporting a new document class is a bit harder.

we'll assume that the style file is called
\begin_inset Flex CharStyle:MenuItem

and it is meant to be used with
\begin_inset Flex CharStyle:MenuItem

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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
report
\end_layout
\end_inset
in this example---so you can fiddle around with the settings for the different
sections if you wish.
\end_layout
\begin_layout Subsection
Layout for a
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
cls
\end_layout
\end_inset
file
\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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
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 DeclareLaTeXClass line will be different.
If your new class is thesis, and it is based upon book, then the line should
read:
\begin_inset Foot
status collapsed
\begin_layout PlainLayout
And it will be easiest if you save the file to
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
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 Section
Declaring a new text class
\end_layout
\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 to much in one sitting.
Go have another adult beverage, just for good measure.
\end_layout
\begin_layout Standard
Here we go!
\end_layout
\begin_layout Standard
Lines in a layout file which begin with a
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
#
\end_layout
\end_inset
are comments.
There is one exception to this rule: all layouts should begin with lines
like:
\end_layout
\begin_layout LyX-Code
\size small
#% Do not delete the line below; configure depends on this
\end_layout
\begin_layout LyX-Code
\size small
#
\backslash
DeclareLaTeXClass{article}
\end_layout
\begin_layout Standard
The second line is used when you configure LyX.
The layout file is read by the LaTeX script
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
chkconfig.ltx
\end_layout
\end_inset
, in a special mode where
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
#
\end_layout
\end_inset
is ignored.
The first line is just a LaTeX comment, and the second one contains the
declaration of the text class.
If these lines appear in a file named
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
article.layout
\end_layout
\end_inset
, then they define a text class of name
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
article
\end_layout
\end_inset
(the name of the layout file) which uses the LaTeX document class
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
article.cls
\end_layout
\end_inset
(the default is to use the same name as the layout).
The string
\begin_inset Quotes eld
\end_inset
article
\begin_inset Quotes erd
\end_inset
that appears above is used as a description of the text class in the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
\bar under
D
\bar default
ocument\SpecialChar \menuseparator
\bar under
S
\bar default
ettings
\end_layout
\end_inset
dialog.
\end_layout
\begin_layout Standard
Let's assume that you wrote your own text class that uses the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
article.cls
\end_layout
\end_inset
document class, but where you changed the appearance of the section headings.
If you put it in a file
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
myarticle.layout
\end_layout
\end_inset
, the header of this file should be:
\end_layout
\begin_layout LyX-Code
\size small
#% Do not delete the line below; configure depends on this
\end_layout
\begin_layout LyX-Code
\size small
#
\backslash
DeclareLaTeXClass[article]{article (with my own headings)}
\end_layout
\begin_layout Standard
This declares a text class
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
myarticle
\end_layout
\end_inset
, associated with the LaTeX document class
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
article.cls
\end_layout
\end_inset
and described as
\begin_inset Quotes eld
\end_inset
article (with my own headings)
\begin_inset Quotes erd
\end_inset
.
If your text class depends on several packages, you can declare it as:
\end_layout
\begin_layout LyX-Code
\size small
#% Do not delete the line below; configure depends on this
\end_layout
\begin_layout LyX-Code
\size small
#
\backslash
DeclareLaTeXClass[article,foo.sty]{article (with my own headings)}
\end_layout
\begin_layout Standard
This indicates that your text class uses the foo.sty package.
Finally, it is also possible to declare classes for DocBook code.
Typical declarations will look like
\end_layout
\begin_layout LyX-Code
\size small
#% Do not delete the line below; configure depends on this
\end_layout
\begin_layout LyX-Code
\size small
#
\backslash
DeclareDocBookClass[article]{SGML (DocBook article)}
\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}
\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; if the name of the classfile
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
LyXDir/layouts/
\end_layout
\end_inset
or to
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
UserDir/layouts
\end_layout
\end_inset
, run
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
\bar under
T
\bar default
ools\SpecialChar \menuseparator
\bar under
R
\bar default
econfigure
\end_layout
\end_inset
, exit LyX and restart it.
Then your new text class should be available along with the others.
\end_layout
\begin_layout Standard
In versions of LyX prior to 1.6, you had to restart LyX to see any changes
you made to your layout files.
As a result, editing layout files could be very time consuming.
Beginning with 1.6, however, you can force a reload of the layout currently
in use by using the LyX function
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
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 (see section
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:bindings"
\end_inset
).
If you want to use this function, then, you should simply enter it in the
mini-buffer.
\emph on
Warning
\emph default
: This is very much an `advanced feature'.
It is

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

] Usually LyX doesn't allow you to insert more than one space between words,
since a space is considered as the separation between two words, not a
character or symbol of its own.
This is a very fine thing but sometimes annoying, for example, when typing
program code or plain LaTeX code.
For this reason,
\begin_inset Flex CharStyle:Code

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 layout can be used
as some kind of break, which does not contain actual text.

] If you put layouts into environments, the leftmargins are not simply added,
but added with a factor
\begin_inset Formula $\frac{4}{depth+4}$
\end_inset
.
Note that this parameter is also used when the margin is defined as
\begin_inset Flex CharStyle:Code

\begin_layout PlainLayout
Manual
\end_layout
\end_inset
or
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
Dynamic
\end_layout
\end_inset
.
Then it is added to the manual or dynamic margin.
\newline
The argument is passed as a string.
For example
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
MM
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
means that the paragraph is indented with the width of
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
MM
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
in the normal font.
You can get a negative width by prefixing the string with

\end_inset
\begin_inset Flex CharStyle:Code

means that the margin depends on the size of the label.
This is used for automatic enumerated headlines.
It is obvious that the headline
\begin_inset Quotes eld

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

\begin_inset Quotes erd
\end_inset
plus the space) than
\begin_inset Quotes eld

\begin_inset Flex CharStyle:Code

the others are static; this is used, for example, for descriptions.
\begin_inset Flex CharStyle:Code

\begin_layout PlainLayout
Right_Address_Box

Standard floats are included in the file
\begin_inset Flex CharStyle:Code

Note however that the

Counters
\end_layout
\begin_layout Standard
\begin_inset CommandInset label
LatexCommand label

\end_inset
Since version 1.3.0 of LyX, it is both possible and necessary to define the
counters (
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
chapter
\end_layout
\end_inset
,
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
figure
\end_layout
\end_inset
, \SpecialChar \ldots{}
) in the text class itself.
The standard counters are defined in the file
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
stdcounters.inc
\end_layout
\end_inset
, so you may have to do no more than add
\end_layout
\begin_layout LyX-Code
Input stdcounters.inc
\end_layout
\begin_layout Standard
to your layout file to get them to work.
But if you want to define custom counters, then you can do so, using the
following parameters:
\end_layout
\begin_layout Description
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
LabelString [string=""]
\end_layout
\end_inset
when this is defined, this string defines how the counter is displayed.
Setting this value sets
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
LabelStringAppendix
\end_layout
\end_inset
to the same value.
The following special constructs can be used in the string:
\end_layout
\begin_deeper
\begin_layout Itemize
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
\backslash
thecounter
\end_layout
\end_inset
will be replaced by the expansion of the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
LabelString
\end_layout
\end_inset
(or
\begin_inset Flex CharStyle:Code
status collapsed

LabelStringAppendix
\end_layout
\end_inset
) of the counter
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
counter
\end_layout
\end_inset
.
\end_layout
\begin_layout Itemize
counter values can be expressed using LaTeX-like macros
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
\backslash
\emph on
numbertype
\emph default
{
\emph on

\emph default
}
\end_layout
\end_inset
, where
\begin_inset Flex CharStyle:Code

\begin_layout PlainLayout

\end_layout
\end_inset
can be:
\begin_inset Foot
status collapsed
\begin_layout PlainLayout

Upgrading old layout files
\end_layout
\begin_layout Standard
The file format of layout files changes from time to time, so old layout
files need to be converted.
This process has been automated since LyX 1.4.0: If LyX reads an old format
layout file it will call the conversion tool
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
LyXDir/scripts/layout2layout.py
\end_layout
\end_inset
and convert it to a temporary file in current format.
The original file is left untouched.
If you want to convert the layout file permanently, just call the converter
by hand:
\end_layout
\begin_layout LyX-Code
python $LyXDir/scripts/layout2layout.py myclass.layout myclassnew.layout
\end_layout
\begin_layout Standard
(You need to replace
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
$LyXDir
\end_layout
\end_inset
with the name of your LyX system directory, unless you happen to have defined
such an environment variable.) Then copy
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
myclassnew.layout
\end_layout
\end_inset
to
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
UserDir/layouts/
\end_layout
\end_inset
.
\end_layout
\begin_layout Standard
The automatic conversion only handles syntax changes.
It cannot handle the case where the contents of included files was changed,
so these will have to be converted separately.
\end_layout
\begin_layout Section
Creating Templates
\begin_inset CommandInset label
LatexCommand label
name "sec:templates"
\end_inset
\end_layout
\begin_layout Standard
Templates are created just like usual documents.
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 defaults in these
cases.
For that reason, the designer of a template should remove the corresponding
commands like
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
\backslash
fontscheme
\end_layout
\end_inset
or
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
\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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
vi
\end_layout
\end_inset
or
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
xedit
\end_layout
\end_inset
.
\end_layout
\begin_layout Standard
Put the edited template files you create in
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
UserDir/templates/
\end_layout
\end_inset
, copy the ones you use from the global template directory in
\begin_inset Flex CharStyle:Code

to the same place, and redefine the template path in the

Note that there is a template which has a particular meaning:
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
defaults.lyx
\end_layout
\end_inset
.
This template is loaded everytime you create a new document with
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
\bar under
F
\bar default
ile
\end_layout
\end_inset
\SpecialChar \menuseparator
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
\bar under
N
\bar default
ew
\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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
Sa
\bar under
v
\bar default
e as Document Defaults
\end_layout
\end_inset
button.

\begin_layout Chapter
Including External Material
\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 CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
Xfig
\end_layout
\end_inset
.
The Xfig application itself works on an original file with the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
fig
\end_layout
\end_inset
-file.
When you want to include the figure in your document, you invoke
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
.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'd either prefer to just include a reference to the figure
or try to invoke some graphics to Ascii converter to make the final result
look similar to the real graphics.
The external material management allows you to do this, because it is parameter
ized on the different export formats that LyX supports.
\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.
\end_layout
\begin_layout Section
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
LatexCommand ref
reference "sec:Security-discussion"
\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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
LyXDir/lib/external_templates

\end_inset
file.
You can place your own version in
\begin_inset Flex CharStyle:Code

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

\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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
$$AbsPath
\end_layout
\end_inset
if an absolute path is required.
\end_layout
\begin_layout Itemize
Use
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
$$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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
$$AbsOrRelPathParent
\end_layout
\end_inset
in order to preserve the user's choice.
\end_layout
\begin_layout Standard
There are special cases where this rule does not work and e.g.
\begin_inset Space ~
\end_inset
relative names are needed, but normally it will work just fine.
One example for such a case is the command
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
ReferencedFile latex "$$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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
.pstex_t
\end_layout
\end_inset
files needs the relative name in order to rewrite the file content.

\begin_inset Note Note

\begin_layout PlainLayout
This section is outdated
\end_layout
\end_inset
The external material feature interfaces with a lot of external programs
and does so automatically, so we have to consider the security implications
of this.
In particular, since you have the option of including your own filenames
and/or parameter strings and those are expanded into a command, it seems
that it would be possible to create a malicious document which executes
arbitrary commands when a user views or prints the document.
This is something we definately want to avoid.
\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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
execvp
\end_layout
\end_inset
-system call rather than the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
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.
In the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
lib/scripts
\end_layout
\end_inset
directory of the LyX installation, you can find a safe wrapper script
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
general_command_wrapper.py
\end_layout
\end_inset
that supports redirection of input and output.
That can serve as an example for how to write safe template scripts.
For a more advanced example that uses
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
fork
\end_layout
\end_inset
and friends, take a look at the
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
pic2ascii.py
\end_layout
\end_inset
converter script.
\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 CharStyle:Code
status collapsed
\begin_layout PlainLayout
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 knowledgable security professional or the LyX development team if you
have any questions about whether a given template is safe or not.
And do this before you use it in an uncontrolled environment.

The LyX Server
\end_layout
\begin_layout Section
Introduction
\end_layout
\begin_layout Standard
The LyX server is a method implemented in LyX that will enable other programs
to talk to LyX, invoke LyX commands, and retrieve information about the
LyX internal state.
This is only intended for advanced users, but they should find it useful.
Please note that, at present,
\emph on
the server does not work on Windows
\emph default
.
\begin_inset Foot
status collapsed
\begin_layout PlainLayout
There is no principled reason it cannot do so.
But none of the developers on Windows® have yet implemented this functionality
there.
\end_layout
\end_inset
\end_layout
\begin_layout Section
Starting the LyX Server
\end_layout
\begin_layout Standard
The LyX server works through the use of a pair of named pipes.
These are usually located in
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
UserDir
\end_layout
\end_inset
and have the names
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.lyxpipe.in
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
and
\begin_inset Quotes eld
\end_inset
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.lyxpipe.out
\end_layout
\end_inset
\begin_inset Quotes erd
\end_inset
.
External programs write into
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.lyxpipe.in
\end_layout
\end_inset
and read back data from
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.lyxpipe.out
\end_layout
\end_inset
.
The stem of the pipe names can be defined in the
\begin_inset Flex CharStyle:MenuItem
status collapsed
\begin_layout PlainLayout
\bar under
T
\bar default
ools\SpecialChar \menuseparator
\bar under
P
\bar default
references
\end_layout
\end_inset
dialog, for example
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
"/home/myhome/.lyxpipe"
\end_layout
\end_inset
.
\end_layout
\begin_layout Standard
LyX will add the '
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.in
\end_layout
\end_inset
' and '
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
.out
\end_layout
\end_inset
' to create the pipes.
The above setting also has the effect of activating the LyX server.
If one of the pipes already exists, LyX will assume that another LyX process
is already running and will not start the server.
To have several LyX processes with servers at the same time, you have to
change the configuration between the start of the programs.
\end_layout
\begin_layout Standard
If you are developing a client program, you might find it useful to enable
debugging information from the LyX server.
Do this by starting LyX as lyx -dbg lyxserver.
\end_layout
\begin_layout Standard
Warning: if LyX crashes, it may not manage to remove the pipes; in this
case you must remove them manually.
If LyX starts and the pipes exist already, it will not start any server.
\end_layout
\begin_layout Standard
Other than this, there are a few points to consider:
\end_layout
\begin_layout Itemize
Both server and clients must run on UNIX or OS/2 machines.
Communications between LyX on UNIX and clients on OS/2 or vice versa is
not possible right now.
\end_layout
\begin_layout Itemize
On OS/2, only one client can connect to LyXServer at a time.
\end_layout
\begin_layout Itemize
On OS/2, clients must open inpipe with
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
O_WRONLY
\end_layout
\end_inset
\end_layout
\begin_layout Standard
mode.
\end_layout
\begin_layout Standard
You can find a complete example client written in C in the source distribution
as
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
development/lyxserver/server_monitor.c
\end_layout
\end_inset
.
\end_layout
\begin_layout Section
Normal communication
\end_layout
\begin_layout Standard
To issue a LyX call, the client writes a line of ASCII text into the input
pipe.
This line has the following format:
\end_layout
\begin_layout Quote
LYXCMD:
\emph on
clientname
\emph default
:
\emph on
function
\emph default
:
\emph on
argument
\end_layout
\begin_layout Description
\emph on
clientname
\emph default
is a name that the client can choose arbitrarily.
Its only use is that LyX will echo it if it sends an answer---so a client
can dispatch results from different requesters.
\end_layout
\begin_layout Description
\emph on
function
\emph default
is the function you want LyX to perform.
It is the same as the commands you'd use in the minibuffer.
\end_layout
\begin_layout Description
\emph on
argument
\emph default
is an optional argument which is meaningful only to some functions (for
instance
\begin_inset Quotes eld
\end_inset
self-insert
\begin_inset Quotes erd
\end_inset
which will insert the argument as text at the cursor position.)
\end_layout
\begin_layout Standard
The answer from LyX will arrive in the output pipe and be of the form
\end_layout
\begin_layout Quote
INFO:
\emph on
clientname
\emph default
:
\emph on
function
\emph default
:
\emph on
data
\end_layout
\begin_layout Standard
where
\emph on
clientname
\emph default
and
\emph on
function
\emph default
are just echoed from the command request, while
\emph on
data
\emph default
is more or less useful information filled according to how the command
execution worked out.
Some commands will return information about the internal state of LyX,
such as
\begin_inset Quotes eld
\end_inset
font-state
\begin_inset Quotes erd
\end_inset
, while other will return an empty data-response.
This means that the command execution went fine.
\end_layout
\begin_layout Standard
In case of errors, the response from LyX will have this form
\end_layout
\begin_layout Quote
ERROR:
\emph on
clientname
\emph default
:
\emph on
function
\emph default
:
\emph on
error message
\end_layout
\begin_layout Standard
where the
\emph on
error message
\emph default
should contain an explanation of why the command failed.
\end_layout
\begin_layout Standard
Examples:
\end_layout
\begin_layout LyX-Code
echo "LYXCMD:test:beginning-of-buffer:" >~/.lyxpipe.in
\end_layout
\begin_layout LyX-Code
echo "LYXCMD:test:get-xy:" >~/.lyxpipe.in
\newline
read a <~/.lyxpipe.out
\newline
echo $a
\end_layout
\begin_layout Section
Notification
\end_layout
\begin_layout Standard
LyX can notify clients of events going on asynchronously.
Currently it will only do this if the user binds a key sequence with the
function
\begin_inset Quotes eld
\end_inset
notify
\begin_inset Quotes erd
\end_inset
.
The format of the string LyX sends is as follows:
\end_layout
\begin_layout Quote
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout PlainLayout
NOTIFY:
\end_layout
\end_inset
\emph on
key-sequence
\end_layout
\begin_layout Standard
where
\emph on
key-sequence
\emph default
is the printed representation of the key sequence that was actually typed
by the user.
\end_layout
\begin_layout Standard
This mechanism can be used to extend LyX's command set and implement macros:
bind some key sequence to
\begin_inset Quotes eld
\end_inset
notify
\begin_inset Quotes erd
\end_inset
, start a client that listens on the out pipe, dispatches the command according
to the sequence and starts a function that may use LyX calls and LyX requests
to issue a command or a series of commands to LyX.
\end_layout
\begin_layout Section
The simple LyX Server Protocol
\end_layout
\begin_layout Standard
LyX implements a simple protocol that can be used for session management.
All messages are of the form
\end_layout
\begin_layout Quote
LYXSRV:
\emph on
clientname
\emph default
:
\emph on
protocol message
\end_layout
\begin_layout Standard
where
\emph on
protocol message
\emph default
can be
\begin_inset Quotes eld
\end_inset
hello
\begin_inset Quotes erd
\end_inset
or
\begin_inset Quotes eld
\end_inset
bye
\begin_inset Quotes erd
\end_inset
.
If
\begin_inset Quotes eld
\end_inset
hello
\begin_inset Quotes erd
\end_inset
is received from a client, LyX will report back to inform the client that
it's listening to it's messages, while
\begin_inset Quotes eld
\end_inset
bye
\begin_inset Quotes erd
\end_inset
sent from LyX will inform clients that LyX is closing.
