SRFI-115: Scheme Regular Expressions

This egg provides the SRFI 115/R7RS-large regular expression library designed by Alex Shinn. It is mainly a layer on top of (chicken irregex). While SRFI 115 is very similar to irregex, changes to naming and procedure design make the two libraries incompatible. With this egg, programs using the SRFI 115 syntax can run on CHICKEN without changes.

See the SRFI for extensive documentation of the library.

Limitations

The regexp decompiler regexp->sre isn't provided. There seems to be no way to implement this on top of (chicken irregex).

Since (chicken irregex) doesn't support Unicode yet, this library doesn't support the grapheme, bog, eog, or w/unicode SRE elements. Using any of these in an expression will raise an error. These parts of the language may be supported in future versions.

w/nocapture is unsupported.
