[erlang-questions] Regular expressons again, an improved regexp module
Mon Sep 11 00:42:36 CEST 2006
After the discussions earlier on about the speed, or lack of, of the
regexp module I have added a regular expression compiler.
There is a new function regexp:compile(RegExp) which takes a regulare
expression parses and compiles it and returns it in a form which can be
used instead of regular expressions in all the matching functions. In
the same way that the return from regexp:parse can.
The new module is a drop-in replacement to the old with the exception of
the new function. One caveat it is not yet possible to compile anchored
I would appreciate it if someone could do some serious testing and see
if there is a significant improvement with real regexps. I have just
tested that it works.
Another question is what people would like to apply the regexps on,
lists or binaries? The module now works on lists but it would not be
difficult to make it work on binaries as well.
