in thread Failed regex: negative look-behinds

therefore, /\A(?<!compiled)[a-zA-Z0-9]+\z/ matches any occurance of one or more alphanumeric at the end of a string that does not follow "compiled"

Which is exactly what I want to match, but the regex doesn't seem to match this any occurance of one or more alphanumeric at the end of a string that does not follow "compiled". *shrug*

    I think they're right up above, most notably ikegami and graff...

    the entire OP regex is anchored at start-of-string, so there's no place to "look-behind"



    --chargrill 
    $/  =  q#(\w)#  ;  sub  sig { print scalar reverse  join  ' ',  @_  } 
+ sig
map { s$\$/\$/$\$2\$1$g && $_ } split( ' ', ",erckha rlPe erthnoa stJu
