Summary description: Build tools to process tokens from an input stream
Announcement text: ----------------------------------------------------------------------
V1.3 of the tokcycle package has been released.
This package helps one to build tools to process tokens from an input stream, on a token-by-token basis, by applying category- based directives to each successive token.
New features include:
1) the xtokcycleenvironment macro has been introduced that allows one to build named tokcycle environments that allow pre- and post-processing directives to the token cycle;
2) the ability to dynamically truncate/discard tokens in various ways from the input stream has been introduced;
3) a form of grouping that limits the scope of your code in the traditional way, while at the same time permitting the trans- mission of the cytoks token list across the group barrier.
4) A TeX count that indicates your current group-depth within the input stream, which can be dynamically used to make conditional decisions in your tokcycle directives.
As always, tokcycle works in both LaTeX and plain TeX.
