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. \layout Section Directions on using macros \layout Subsection 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. \layout Subsection How to navigate \layout Description With \protected_separator the \protected_separator arrow \protected_separator 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. \layout Description With \protected_separator the \protected_separator mouse: As usual, click on the desired argument box. Sometimes this fails if the box is empty or too small. \layout Standard Currently the user can only define command macros, but internally it's possible to define also environment macros. \layout Standard \cursor 358 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 \family typewriter \backslash binom \family default . [ \emph on 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 \emph default . AAS] \the_end [ Dauer der Verarbeitung: 0.73 Sekunden ] |
