\begin_layout Title
Macro Testcases
\end_layout

\begin_layout Enumerate
Simple macro definitions with position awareness:
 
\begin_inset FormulaMacro
\newcommand{\bla}{42}
\end_inset


\begin_inset Formula 
\[
\bla\mbox{ should look like }42
\]

\end_inset

now redefined as 
\begin_inset FormulaMacro
\renewcommand{\bla}{21}
\end_inset

,
 such that
\begin_inset Formula 
\[
\bla\mbox{ should look like }21.
\]

\end_inset


\end_layout

\begin_layout Enumerate
Redefinitions of macros appearing in the definition of another macro:
 
\begin_inset FormulaMacro
\newcommand{\fooa}{x}
\end_inset


\begin_inset FormulaMacro
\newcommand{\foob}[1]{(#1\fooa)}
\end_inset


\begin_inset FormulaMacro
\renewcommand{\fooa}{y}
\end_inset

 with the \SpecialChar TeX
 code
\begin_inset listings
inline false
status open

\begin_layout Plain Layout


\backslash
newcommand{
\backslash
fooa}{x} 
\end_layout

\begin_layout Plain Layout


\backslash
newcommand{
\backslash
foob}[1]{(#1
\backslash
fooa)}
\end_layout

\begin_layout Plain Layout


\backslash
renewcommand{
\backslash
fooa}{y}
\end_layout

\end_inset

gives the following:
\begin_inset Formula 
\[
\foob{\fooa}\mbox{ should look like }(yy)
\]

\end_inset


\end_layout

\begin_layout Enumerate
Arity change:
 
\begin_inset FormulaMacro
\newcommand{\foo}{-}
\end_inset


\begin_inset FormulaMacro
\renewcommand{\foo}[2]{(#1,#2)}
\end_inset


\begin_inset Formula 
\[
\foo{abc}d\mbox{ should look like }(abc,d)\mbox{ if the second foo is there, otherwise like }-{abc}d
\]

\end_inset


\end_layout

\begin_layout Enumerate
Arity change with incomplete arguments at line end:
 
\begin_inset FormulaMacro
\renewcommand{\foo}{-}
\end_inset


\begin_inset FormulaMacro
\renewcommand{\foo}[2]{(#1,#2)}
\end_inset

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

\end_inset


\end_layout

\begin_layout Enumerate
Recursion:
 
\begin_inset FormulaMacro
\renewcommand{\foo}[1]{\foo{#1}{}}
\end_inset

.
 The inner foo should not we resolved as \SpecialChar 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

\begin_layout Enumerate
Scripts:
 
\begin_inset FormulaMacro
\renewcommand{\foo}[3][A][B]{(#1,#2)#3}
\end_inset


\begin_inset Formula 
\[
\foo[a]{}^{4}[b]c_{1}\mbox{ should look like }(a,B)\sqcup^{4}[b]c_{1}
\]

\end_inset


\begin_inset Formula 
\[
\foo[a]c^{3}\mbox{ should look like }(a,B)c^{3}
\]

\end_inset


\end_layout

\begin_layout Enumerate
Multiple optional parameters:
\begin_inset FormulaMacro
\renewcommand{\foo}[3][a][b][c]{(#1,#2,#3)}
\end_inset


\begin_inset Separator latexpar
\end_inset


\end_layout

\begin_deeper
\begin_layout Enumerate
\begin_inset Formula $\foo[][B]123\mbox{ should be }(a,B,c)123$
\end_inset


\end_layout

\begin_layout Enumerate
\begin_inset Formula $\foo[][][C]123\mbox{ should be }(a,b,C)123$
\end_inset


\end_layout
