Ah, okay. Though it triggers a "Pcre.Error" with the rewritten auto-linux file: """ Generating (ongoing) auto-linux E: Pcre.Error(_) """ I suspect that the underlying regex engine does not like that enormous expression. Besides that, it does seem to work and it takes only 3 minutes (excluding the above mentioned file for obvious reasons). If you want, I can send you the resulting file that ben/Pcre doesn't like. > The code for ~ "foo" does indeed look suboptimal (to say the least)... > :) >> Thanks for the tip; it does seem to improve the general performance of >> these files considerably.
