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

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

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

- which is the internal construct LyX uses to render the screen display.
-
+\begin_layout Plain Layout
+Some commands are sufficiently complex that they are

+hardcoded
\begin_inset Quotes erd
\end_inset
- and

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

+ and enjoy one or two of your favorite adult beverages; more if you are

-Including External Material
-\end_layout
-\begin_layout Standard
-The use of material from sources external to LyX is covered in detail in

- This part of the manual covers what needs to happen behind the scenes for
- new sorts of material to be included.

-\begin_layout Section
-How does it work?
-\end_layout
+\end_inset
-\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

\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.
+, lest it be ineffective.
\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_layout Description
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout Plain Layout
-Xfig
+LabelString
\end_layout
\end_inset
-.
- The Xfig application itself works on an original file with the
+ What will be displayed on the button or elsewhere as the inset label.
+ Some inset types (TeX code and Branch) modify this label on the fly.
+\end_layout
+
+\begin_layout Description
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout Plain Layout
-.fig
+LatexName
\end_layout
\end_inset
- extension.
- Within XFig, you create and change your figure, and when you are done,
- you save the
+ The name of the corresponding LaTeX stuff.
+ Either the environment or command name.
+\end_layout
+
+\begin_layout Description
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout Plain Layout
-fig
+LatexParam
\end_layout
\end_inset
--file.
- When you want to include the figure in your document, you invoke
+ The optional parameter for the corresponding
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout Plain Layout
-transfig
+LatexName
\end_layout
\end_inset
- in order to create a PostScript file that can readily be included in your
- LaTeX file.
- In this case, the
+ stuff, including possible bracket pairs like
\begin_inset Flex CharStyle:Code
status collapsed
\begin_layout Plain Layout
-.fig
+[]
\end_layout
\end_inset
- file is the original file, and the PostScript file is the produced file.
+.
+ This parameter cannot be changed from within LyX.
\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 Description
+\begin_inset Flex CharStyle:Code
+status collapsed
-\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.

+\begin_layout Standard
+The external material feature is based on the concept of a

+\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

+ Furthermore, it is possible to roll your own template to support a specific

+ will submit all the templates you create so we can include them in a later
+ LyX version.

+\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

\begin_layout Plain Layout

+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 parametri
+zed on the different export formats that LyX supports.

+\begin_layout Standard
+Besides supporting the production of different products according to the
+ exported format, it supports tight integration with editing and viewing

+ 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

-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.
