( #3333=superdoc: print w/ replies, xml ) Need Help??

w.r.t the warning redirect, I've been preferring a local clobber of the __WARN__ handler recently. It's less intimidating to the unwashed, and expires naturally.

use strict; use warnings; my $log = parse_regex( q#(\\.|["']|x)# ); print $log; sub parse_regex { my ($regex) = @_; # Catch and stash warnings my $parselog = ''; local $SIG{__WARN__} = sub { $parselog .= $_ for @_; }; # --- compile regex eval q{ use re 'debug'; qr/$regex/; }; return $parselog; }

Best of luck; strikes me as an interesting challenge. Is use re 'debug'; output stable enough for automated parsing?

Update: Huh, the debug actually bypasses the warning handler and prints directly to STDERR. Now starting penance.
