kbauer / Meaning
Created July 15, 2015 15:52
For debugging/learning LaTeX internals it is useful to dump the definition of commands. Reading the output of `\show` from the console however is inconvenient. The command `\meaning` is useful here (as it prints the definition to the document) but limited. `\mymeaning` is a wrapper, where you specifiy the name of a macro rather than the `\macro`…
% \mymeaning{command} -> Definition of \command
\makeatletter
\newcommand{\mymeaning}[1]{
