Re: [HTCondor-users] job transform: change requirement condition?

[Michael Pelletier <Michael.V.Pelletier@xxxxxxxxxxxx>]

I think you're right that it's a type issue - regexps returns a String type, which would just be a constant once evaluated. So maybe just add an eval() around the regexps?

Hi Michael,

thanks for the tip with regexps. Unfortunately, the way I have added it to my job transform seems to have no effect so far.
The job transform should in principle format the Requirement string [1] but still the resulting job's ad is the old one [2]

>From the documentation on regexps I would assume that it should work - but I am not sure, if 'Requirements' is a 'string target' (should be as a class ad, or?). Scanning through target also should match and replace substrings, or?

Cheers and thanks,
  Thomas

String regexps
    (String pattern, String target, String substitute [ , String options
]) Uses the description of a regular expression given by string pattern to scan through the string target. When target is a regular expression as described by pattern, the string substitute is returned, with backslash expansion performed. If any argument is not a string, returns ERROR.
