'this is fixed' ; ;; my $START = qr{ START \s* \K }xms; my $END = qr{ (?= \s* END) }xms; my $not_end = qr{ (?! $END) . }xms; ;; my ($extract) = $line =~ m{ $START $not_end* should $not_end* $END }xmsg; print qq{[[$line]]}; print qq{'$extract'}; " [[Hello hello START this is comment END START this is still comment END START this should still be comment END this is fixed]] 'this should still be comment'

[Corion]: 1nickt: That one sounds sensible as it will tell you when it found an error
[1nickt]: Throws on error, I believe
[1nickt]: But should handle month as number or word
[TCLion]: I am breaking down the line and putting the date in the correct order during output
[TCLion]: at least that's the plan
[1nickt]: Corion this looks good, from the pod: "there are 9000+ variations that are detected correctly in the test files (see t/data/* for most of them). If you can think of any that I do not cover, please let me know."
[TCLion]: some moron put the date like this : Mon Feb 20 09:31:30 2017
[Corion]: 1nickt: Yes, the module sounds promising indeed
[1nickt]: "putting the date in correct order" how?
