LanX has asked for the wisdom of the Perl Monks concerning the following question:
I looked in App::a2p trying to understand how awk is translated to Perl
... but it's written in C, which is
- a far from being my best language and
- unfortunate from a maintenance perspective.
From https://metacpan.org/source/LEONT/App-a2p-1.013/a2p.c
Question: Is there an obvious way to translate this to Perl regexes?
A result could be a parse tree, inspected by a walker to generate Perl code.
Cheers Rolf

UPDATE
I just realized that the real YACC/LEX rules are only available on GitHub
https://github.com/Leont/app-a2p/blob/master/a2p.y
Leon pruned this file from the CPAN version.
This makes obviously more sense than decipering the generated C-files.
