regexp_opt - Convert list of strings to a regular expression
use List::Regexp qw(:all);
my $s = regexp_opt(@strings);
my $s = regexp_opt(\%opts, @strings);
Returns a regular expression that will match any string from the input list @strings. First argument can be a reference to a hash, which controls how the regexp is built.
Valid keys are:
- type => pcre|posix|emacs
Controls the flavor of the generated expression: Perl-compatible (the default), POSIX extended, or Emacs.
- match => default|exact|word
If default, the expression will match any word from @strings appearing as a part of another word.
If exact, the expression will match a word from @strings appearing on a line alone.
If word, the expression will match single words only.
- debug => 0|1
If 1, enable debugging output.
- group => 0|1
If 1, enclose entire regexp in a group.
