( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hey Jenda,

This is the one I was looking for. Pointing out the relative stupidity of my regex. I was checking for empty string, but then lost the fact that I didn't need to require the 'd' or 'h' portion, thus allowing for the deletion of the '|'. And at one point, I did correctly have the ^(?:...)$ wrapping the entire match, but lost it in one of my incantations.

So, the final form I've chosen is:
if ( $value and $value !~ /^(?:(\d+)d)?(?:\s*(\d+)h)?$/i ) { $result = "Please only enter time in one of these three formats: ' +3d', '4d 3h', '22h'"; } else { $day = $1 || 0; $hour = $2 || 0; }
And it seems to work!

Thanks,
LogicalChaos

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.
