Hello Polyglot,

I'm not sure if this will buy you any improvements, but you might try the qr operator. You might even already be using qr depending on what &composeRegex returns.

Quoting from the documentation:


This operator quotes (and possibly compiles) its STRING as a regular expression. STRING is interpolated the same way as PATTERN in m/PATTERN/.

I think this example (also from the documentation) gives a good idea of what is possible.

my $sentence_rx = qr{ (?: (?<= ^ ) | (?<= \s ) ) # after start-of-string or # whitespace \p{Lu} # capital letter .*? # a bunch of anything (?<= \S ) # that ends in non- # whitespace (?<! \b [DMS]r ) # but isn't a common abbr. (?<! \b Mrs ) (?<! \b Sra ) (?<! \b St ) [.?!] # followed by a sentence # ender (?= $ | \s ) # in front of end-of-string # or whitespace }sx; local $/ = ""; while (my $paragraph = <>) { say "NEW PARAGRAPH"; my $count = 0; while ($paragraph =~ /($sentence_rx)/g) { printf "\tgot sentence %d: <%s>\n", ++$count, $1; } }

I hope this helps, even if only a little.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
