:: Very useful. Would it also be possible to support regexes for (1) unix/linux utilities sed and grep and (2) Visual studio regexes?Tue, 21 Oct 2014 09:18PM
:: Feature request: Allow user to supply a list of strings, and for txt2re to generate a single regex that would match them all. Thanks,Tue, 21 Oct 2014 09:22PM

anon:: I second the feature request for a generic regex rather than a whole script. As great as it is having the whole script there, just the regex would be ideal sometimes.Fri, 7 Nov 2014 04:03PM
