Introduction
|
|
\layout Standard
|
|
|
|
LyX version 0.12 allows the user to define macros.
|
|
An user defined macro in math mode is not a red colored name that LyX didn't
|
|
know how to draw (formerly known as macro mode, now simply TeX mode).
|
|
A macro definition box appears on screen as a grayed button with the name
|
|
of the macro in blue (math color).
|
|
But if you click on it, it will appear as a normal math box to allow you
|
|
edit it.
|
|
Just try it:
|
|
\begin_inset FormulaMacro
|
|
\newcommand{\macro}{a+b}
|
|
|
|
\end_inset
|
|
|
|
|
|
\layout Standard
|
|
|
|
Now, to use this macro in other math boxes just type the name in TeX mode,
|
|
in this case
|
|
\family typewriter
|
|
|
|
\backslash
|
|
macro
|
|
\family default
|
|
, and it will be automatically expanded:
|
|
\begin_inset Formula \( c=\macro \)
|
|
\end_inset
|
|
|
|
.
|
|
As you can verify, the cursor can't go inside the macro, the whole macro
|
|
is like a single character, and the TeX generated code of this expression
|
|
is
|
|
\family typewriter
|
|
c =
|
|
\backslash
|
|
macro.
|
|
\layout Standard
|
|
|
|
However the cursor could go inside of some kind of macros, those that have
|
|
|
|
\emph on
|
|
arguments
|
|
\emph default
|
|
.
|
|
In a macro definition box an argument looks like a
|
|
\family typewriter
|
|
#
|
|
\family default
|
|
followed by the argument number:
|
|
\begin_inset FormulaMacro
|
|
\newcommand{\macrowarg}[1]{2+\sqrt{#1 }}
|
|
|
|
\end_inset
|
|
|
|
|
|
\layout Standard
|
|
|
|
Once expanded, this macro includes the usual empty rectangle to indicate
|
|
that you can insert there whatever you want:
|
|
\family typewriter
|
|
|
|
\backslash
|
|
macrowarg =
|
|
\begin_inset Formula \( \macrowarg{} \)
|
|
\end_inset
|
|
|
|
|
|
\family default
|
|
.
|
|
Example:
|
|
\begin_inset Formula \( b=\macrowarg{x-2} \)
|
|
\end_inset
|
|
|
|
.
|
|
|
|
\layout Standard
|
|
|
|
When exported to LaTeX, a macro definition will produce the command
|
|
\family typewriter
|
|
|
|
\backslash
|
|
newcommand.

How to create them
|
|
\layout Standard
|
|
|
|
To create a macro definition box use this syntax in the minibuffer:
|
|
\layout Standard
|
|
|
|
|
|
\family typewriter
|
|
math-macro <macro name> [number of arguments]
|
|
\layout Standard
|
|
|
|
Par example
|
|
\family typewriter
|
|
|
|
\backslash
|
|
macro
|
|
\family default
|
|
was created with
|
|
\begin_inset Quotes eld
|
|
\end_inset
|
|
|
|
|
|
\family typewriter
|
|
math-macro macro
|
|
\family default
|
|
|
|
\begin_inset Quotes erd
|
|
\end_inset
|
|
|
|
, and
|
|
\family typewriter
|
|
|
|
\backslash
|
|
macrowarg
|
|
\family default
|
|
was created with
|
|
\begin_inset Quotes eld
|
|
\end_inset
|
|
|
|
|
|
\family typewriter
|
|
math-macro macrowarg 1
|
|
\family default
|
|
|
|
\begin_inset Quotes erd
|
|
\end_inset
|
|
|
|
.
|
|
\layout Standard
|
|
|
|
To insert an argument mark (only inside a macro definition box) use this:
|
|
\layout Standard
|
|
|
|
|
|
\family typewriter
|
|
math-macro-arg <number>
|
|
\layout Standard
|
|
|
|
The argument mark in
|
|
\family typewriter
|
|
|
|
\backslash
|
|
macrowarg
|
|
\family default
|
|
was introduced with
|
|
\begin_inset Quotes eld
|
|
\end_inset
|
|
|
|
|
|
\family typewriter
|
|
math-macro-arg 1
|
|
\family default
|
|
|
|
\begin_inset Quotes erd
|
|
\end_inset
|
|
|
|
.
|
|
\layout Standard
|
|
|
|
You can use no more than 9 arguments, numbered from 1 to 9.
|
|
An argument can be repeated inside the macro definition box, but of course
|
|
can be edited only once.
|
|
A number can't be greater than the number of arguments originally allowed
|
|
for the macro.

keys: Opening a macro form the left side will put the cursor in the first
|

argument, to move to the second argument use the TAB key.
|
|
Remember that pressing the Space bar will get the cursor out and at the
|
|
right side of the macro.

Sometimes this fails if the box is empty or too small.

Currently the user can only define command macros, but internally it's possible
|
|
to define also environment macros.

There are several predefined macros, mainly to allow AMS-LaTeX users to
|
|
use AMS macros in a WYSIWYM way, like
|
|
\family typewriter
|
|
|
|
\backslash
|
|
cases
|
|
\family default
|
|
and
|
|

Pre 0.12 Note:
|
|
\family typewriter
|
|
|
|
\backslash
|
|
cases
|
|
\family default
|
|
are currently disabled because after some simplification and improving
|
|
of the macro stuff, the only valid arguments are subparagraphs (neither
|
|
tabs nor newlines).
|
|
Perhaps they will be again included before 0.12
