show2e – Vari­ants of \show for LaTeX2ε

This small pack­age aims at mak­ing de­bug­ging (es­pe­cially in an in­ter­ac­tive way) eas­ier, by pro­vid­ing \show vari­ants suited to LaTeX2ε com­mands (whether with op­tional ar­gu­ments or ro­bust) and en­vi­ron­ments. The vari­ant com­mands also dis­play the in­ter­nal macros used by such com­mands, if any. The \showcs vari­ant helps with macros with ex­otic names.
