(LaTeX) Show / redefine internal LaTeX macros - deepsoul

Fri, 07 Aug 2009 14:08:16 UTC

These four LaTeX control sequences are workalikes of the built-ins \show, \showthe and \def and of a command sequence call. Unlike the usual variants, they work on internal macros which contain characters with the "wrong" category code, such as "@". They take the name of the command sequence (without the leading "\") as their argument. The \scrollmode is not necessary, it just saves you pressing Return for every listing output. The \obeyspaces is needed only if you want to display or manipulate control sequences whose names contain spaces. Gratuitous use of \don and/or \defn will probably break LaTeX.

(LaTeX) Prevent image degradation when generating PDF - deepsoul

By default ps2pdf re-encodes images, which usually reduces their quality. The commandline below prevents that. It also embeds fonts into the PDF, making it more portable. Substitute -sPAPERSIZE=letter if you are American.
