6.15 Regular Expressions

A regular expression (or regexp) is a pattern that describes a whole class of strings. A full description of regular expressions and their syntax is beyond the scope of this manual.

If your system does not include a POSIX regular expression library, and you have not linked Guile with a third-party regexp library such as Rx, these functions will not be available. You can tell whether your Guile installation includes regular expression support by checking whether (provided? 'regex) returns true.

The following regexp and string matching features are provided by the (ice-9 regex) module. Before using the described functions, you should load this module by executing (use-modules (ice-9 regex)).
