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

To be fair, while it's not a panacea, Parse::RecDescent is actually a pretty good tool for exactly this kind of job. When I recently tried a similar exercise myself, my first readthrough of the manual left me sceptical, but in practice I was pleasantly surprised at how easy it turned out to be to parse expressions of this precise sort with Parse:RecDescent. Whereas I've never managed to get my head round LALR(1) parsing of the sort that Limbic~Region found so intuitive.

Though I suppose that just reinforces the point that one shouldn't assume that a tool is the right tool for one's own project just because other people prefer it...

(I do find myself wondering whether the love affair with Yapp would have continued beyond the first shift/reduce conflict...)

Title:
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.
