[tap] ANNOUNCE: TAP::Spec::Parser - a TAP parser based on the draft grammar

[Andrew Rodland <[e-mail]>]

(Reposted here from tap-l, which was apparently the wrong list)

Per Schwern's request at YAPC, I've written a parser based on the grammar in 
the IETF draft standard 
<http://testanything.org/wiki/index.php/TAP_at_IETF:_Draft_Standard> to help 
make sure that it's correct and well-exercised. The code is at 
http://github.com/arodland/TAP-Spec-Parser and it's currently in a working 
alpha state. It uses a Regexp::Grammars grammar, with the relevant portions of 
the spec grammar interleaved in comments.

Current TODOs for TAP::Spec::Parser:
* Implement skipping "junk" lines.
* (Optionally?) remove the '' key (which stores the entire matched text) from 
  result hashes.
* Convince Regexp::Grammars to call object constructors instead of just
  blessing hashes (to play better with Moose)
* Investigate segfaults in global destruction after parsing.

Draft grammar issues identified so far:
* The Description rule doesn't make any mention of the optional "-" SP at the
  beginning of the description (discussed with Schwern).
* Plan-Todo looks like it should have SP before "todo".
