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.
