This allows one to (re)define helper macros +% without worrying about accidentally changing the functionality of another +% package's or the user's definitions. Additionally, it allows recursive +% macros to have some definitions persist between calls, and others be local. +% +% \section{Usage} +% I give the usage and specification of every macro defined. I give bugs when +% I know them (please email me if you find other bugs, or have fixes for the +% bugs I list). I sometimes give extra description or justification. +% +% \DescribeMacro{\manyaftergroup} +% \noindent Usage: |\manyaftergroup|\marg{tokens} \par\noindent +% Specification: The \meta{tokens} get placed after the current group \par\noindent +% Bugs: No braces are permitted, spaces are stripped +% +% I've often wanted to use \TeX's |\aftergroup| with a variable-length +% argument. This macro allows this. It is expandable (may be used in +% |\edef|), but it gobbles spaces. +% +% ToDo: Write a version of this macro that preserves spaces, allows braces. +% +% \DescribeMacro{\locallydefine} +% \noindent Usage: |\locallydefine|\marg{macro}\marg{processing} \par\noindent +% Specification: Execute \meta{processing} inside of a group, and make +% the definition of |\macro| persist after the group ends. \par\noindent +% Bugs: Changes via |\let| to an unexpandable macro yield an infinite recursive +% loop. +% +% Normally, when you define a macro in a group, it's definition reverts after +% the group ends, unless you use |\global|. If you use |\global|, then the +% new definition replaces the current definition on all levels. This macro +% provides something in between. +% +% \DescribeMacro{\DeclareNonlocalMacro} +% \noindent Usage: |\DeclareNonlocalMacro|\marg{macro} \par\noindent +% Specification: Any changes to the definition of |\macro| persist +% after the end of the current group. \par\noindent +% Bugs: Changes via |\let| to an unexpandable macro yield an infinite recursive +% loop. Only works with |\begingroup| |\endgroup| (not with braces). +% +% This macro generalized |\locallydefine|. +% +% +% \DescribeMacro{\DeclareNonlocalCount}\DescribeMacro{\DeclareNonlocalLength}\DescribeMacro{\DeclareNonlocalToks} +% \noindent Usage: |\DeclareNonlocalCount|\marg{count} \par\noindent +% \phantom{Usage:} |\DeclareNonlocalLength|\marg{length} \par\noindent +% \phantom{Usage:} |\DeclareNonlocalToks|\marg{toks} \par\noindent +% Specification: Any changes to the value in \meta{register} persist +% after the end of the current group. \par\noindent +% Bugs: Only works with |\begingroup| |\endgroup| (not with braces). Only +% works if the argument is a single token. +% +% These do the same thing to registers (\meta{count}s, \meta{length}s, and +% \meta{tok}s) that |\DeclareNonlocalMacro| does to macros. +% +% +% \DescribeMacro{\savevalues}\DescribeMacro{\restorevalues} +% \noindent Usage: |\savevalues|\marg{list of macros (no separator)} \par\noindent +% \phantom{Usage:} |\restorevalues|\marg{list of macros (no separator)} \par\noindent +% Specification: Every token in the passed argument is backed up by +% |\savevalues|, and the most recently backed up values are restored by +% |\restorevalues|. +% +% +% \DescribeMacro{\makecommandslocal} +% \noindent Usage: |\makecommandslocal|\marg{list of macros (no separator)}\marg{code} \par\noindent +% Specification: Every token in the first argument is made local to \meta{code}; +% changes made to their definitions do not perist outside of \meta{code}. +% +% This macro is the natural opposite of |\DeclareNonlocalMacro|; it allows +% some macros to behave as if \meta{code} was inside a group, while the rest +% of the macros behave as if they were not. +% +% +% \DescribeMacro{\ignoreglobal}\DescribeMacro{\obeyglobal}\DescribeMacro{\unignoreglobal} +% \noindent Usage: |\ignoreglobal| \par\noindent +% \noindent Usage: |\unignoreglobal| \par\noindent +% \noindent Usage: |\obeyglobal| \par\noindent +% Specification: The macro |\ignoreglobal| causes global changes, such as +% |\edef|, |\xdef|, and those prefaced by |\global|, to be local. The macro +% |\obeyglobal| causes these to be treated as global. The macro +% |\unignoreglobal| undoes the changes made by the last |\ignoreglobal|. If +% you call |\ignoreglobal| twice, then you must call |\unignoreglobal| twice to +% allow global changes. +% +% \DescribeMacro{\makecounterslocal} +% \noindent Usage: |\makecounterslocal| \par\noindent +% Specification: The macro |\makecounterslocal| redefines the \LaTeX{} +% \meta{counter} macros so that their changes are local, instead of global. +% At the end of the group in which |\makecounterslocal| is called, +% \meta{counter} macros revert to being global. +% +% \StopEventually{\PrintChanges\PrintIndex} +% +% \section{Implementation} +% \subsection{Helper functions} +% The following definitions are preliminary, to allow various tricks with |\def|. +% \begin{macrocode} +\def\@nil{\@nil\relax} % this way, I'll know if I've messed up; I'll get +% a stack overflow error. +\def\if@nil#1{\@if@nil#1\@@nil} +\def\@if@nil#1#2\@@nil{\ifx\@nil#1} +% \end{macrocode} +% +% \begin{macro}{\locality@global@non@collision@unique@count} +% At various places, I want to have a macro associated with a certain name +% which hasn't been used before.
