> \b{wb} doesn't seem to take initial ones as part of words

good catch!

> my conclusion is that the only way to handle the OP problem in a way fully consistent with \w{wb} semantics is to just split using it, and maybe repack non word fragments afterwards

My intuition says split on non-words like whitespace, reject "words" without \w or equivalent characters and repack the rest afterwards.

I doubt it's possible to cover all desirable edge cases by \b{wb} this will depend on the user's perspective, especially when considering multi-language environments and unicode.

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