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

An easily extendable solution:

{ for ($text) { # Alias $_ to $text. /\G `` (.*?) `` /gcsx && do { print($1 ); redo }; /\G \*\* (.*?) \*\* /gcsx && do { print("<b>$1</b>"); redo }; /\G ( . # Catchall. (?: # These four lines are optional. (?!``) # They are here to speed things up (?!\*\*) # by avoiding calling print for .)* # single characters. ) /gcsx && do { print($1); redo }; } }

Handles mismatched ** and `` by treating them as normal characters.


  • Removed "\n"s from prints.
  • Added /s option to regexps, since I'm guessing newlines are not special.
  • The 1st .*? was ((?:(?!``).)*
  • The 2nd .*? was ((?:(?!\*\*).)*


foreach ( '**bold**', '``**bold**``', '**``bold``**', '**bold** test ** test', '``text`` test `` test', ) { print('in: ', $_, $/, 'out: '); TOKENIZER: { ... } print($/, $/); } __END__ in: **bold** out: <b>bold</b> in: ``**bold**`` out: **bold** in: **``bold``** out: <b>``bold``</b> in: **bold** test ** test out: <b>bold</b> test ** test in: ``text`` test `` test out: text test `` test

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 or How to display code and escape characters are good places to start.
