Suppose we implement a command: fossil grep REGEXP FILENAMEGLOB Which searches all historical versions of files that match FILENAMEGLOB for patterns that match REGEXP. Suppose for concreteness that the regular expression is "xyzzy" and the file is "ex1.txt". If there are 1000 different revisions of ex1.txt, does it search them all looking for "xyzzy" and show each hit? Or did it stop going backwards in time at the first hit it find? > > Regards, > Lluís. > _______________________________________________ > fossil-users mailing list > [email protected] > http://lists.fossil-scm.org:8080/cgi-bin/mailman/listinfo/fossil-users > -- D.
