$ perl -MYAPE::Regex::Explain -le 'print YAPE::Regex::Explain->new(shift)->explain' ':\/[^,\s]*'


The regular expression:

(?-imsx::\/[^,\s]*)

matches as follows:

NODE                     EXPLANATION
----------------------------------------------------------------------
(?-imsx:                 group, but do not capture (case-sensitive)
                         (with ^ and $ matching normally) (with . not
                         matching \n) (matching whitespace and #
                         normally):
----------------------------------------------------------------------
  :                        ':'
----------------------------------------------------------------------
  \/                       '/'
----------------------------------------------------------------------
  [^,\s]*                  any character except: ',', whitespace (\n,
                           \r, \t, \f, and " ") (0 or more times
                           (matching the most amount possible))
----------------------------------------------------------------------
)                        end of grouping
----------------------------------------------------------------------
