I'm a big fan of extended regular expressions, but I just
wrote one that didn't work as I expected. This code:
$line =~ s|[\000-\010 # nul-bs
\012-\037 # nl-us
\177-\377'] # del-... and '
||gx; # Punt weird characters.
produced the nastygram:
Invalid [] range "l-b" in regex;
marked by <-- HERE in m/[\000-\010 # nul-b <-- HERE s
\012-\037 # nl-us
\177-\377'] # del-...
/ at /home/rdm/bin/log_load.pl line 206.
but this code:
$line =~ s|[\000-\010\012-\037\177-\377']||g;
sails right through. Is this a bug or a (mis-)feature?
-r
P.S. "This is perl, v5.8.6 built for x86_64-linux-thread-multi"
