[ast-developers] Renaming pgrep (grep -P) pcregrep as builtin?

[Joshuah Hurst]

Could the pgrep (grep -P) utility please be resurrected as pcregrep
(perl compatible regular expression grep) that builtin pcregrep in a
ksh shell works, please? The system's pcregrep is awful slow compared
to AST grep and as builtin matching short strings it would even be
much faster.

I specifically avoided that because ast does not use the PCRE library
if others don't think this is a problem b_pcregrep can be added to libcmd

Couldn't libast use the libpcre library if it is available?
