tokcycle – Build tools to process tokens from an input stream

The tokcycle package helps one to build tools to process tokens from an input stream. If a macro to process an arbitrary single token can be built, then tokcycle can provide a wrapper for cycling through an input stream (including macros, spaces, and groups) on a token-by-token basis, using the provided macro on each successive character.

tokcycle characterizes each successive token in the input stream as a Character, a Group, a Macro, or a Space. Each of these token categories are processed with a unique directive, to bring about the desired effect of the token cycle. If condition flags are provided to identify active, implicit, and catcode-6 tokens as they are digested. The package provides a number of options for handling groups.
