( #3333=superdoc: print w/replies, xml ) Need Help??
After a recent project that used File::Spec, File::Find, and others I'd like to add another section to tye's File::Spec review ('the good', 'the bad', and 'the ugly') ...

(Please forgive me for using unix paths in the following discussion)

The Unexpected

File::Spec->canonpath( $path ); does remove extra '/' and '/.' from paths, but it does not, however, fix paths like '/a/1/../2' into '/a/2'.

To do that I had to resort to regexps something like $path =~ s(\.\./)()g - which introduces platform-specific code and defeats the purpose of using File::Spec in the first place.

Q: What is the correct (x platform) method for removing 'dir/..' from paths?

A note on my ignorance: None of the systems that I use perl on (all 5.005_003 or older) have documentation (or code) for either abs2rel() or rel2abs() in File::Spec, or File::Spec::Unix. Are these new in 5.6? Perhaps theses functions are part of the answer to my question.

All the best,

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.
