Arity change with incomplete arguments at line end:

\end_inset

\begin_inset Formula \[
|

\frac{\foo{abc}{}}{1}\mbox{ should be }\frac{(abc,\,)}{1}\mbox{ if the second foo is defined. Otherwise }\frac{-{abc}{}}{1}\]

Recursion:
|
||
|
|
\begin_inset FormulaMacro
|
||
|
|
\renewcommand{\foo}[1]{\foo #1{}}
|
||
|
|
\end_inset
|
||
|
|
|
||
|
|
.
|
||
|
|
The inner foo should not we resolved as TeX would give a infinite recursion.
|
||
|
|
\end_layout
|
||
|
|
|
||
|
|
\begin_layout Enumerate
|
||
|
|
Recursive usage:
|
||
|
|
\begin_inset FormulaMacro
|
||
|
|
\renewcommand{\foo}[3]{\frac{{\displaystyle #1}\,{\displaystyle #2}}{{\displaystyle #3}}}
|
||
|
|
\end_inset
|
||
|
|
|
||
|
|
can be used to create tree-like structures like this one:
|
||
|
|
\begin_inset Formula \[
|
||
|
|
\foo{\foo{42}{\foo{asdf}{asdf}{asdf}}{21}}{\foo{asdf}{asdf}{asdf}}{asdf}.\]
|
||
|
|
|
||
|
|
\end_inset
|
||
|
|
|
||
|
|
|
||
|
|
\end_layout
|
||
|
|
|
||
|
|
\begin_layout Enumerate
|
||
|
|
Folding/Unfolding:
|
||
|
|
\begin_inset FormulaMacro
|
||
|
|
\renewcommand{\foo}[2]{<#1|#2>}
|
||
|
|
\end_inset
|
||
|
|
|
||
|
|
.
|
||
|
|
Start using Ctrl-+ and Ctrl-- when you are inside of the macro to fold
|
||
|
|
and unfold, e.g.
|
||
|
|
here:
|
||
|
|
\begin_inset Formula \[
|
||
|
|
\foo{\foo{42}{12}}{\foo{21}4}.\]
|
||
|
|
|
||
|
|
\end_inset
|
||
|
|
|
||
|
|
|
||
|
|
\end_layout
