libgnuregex

GNU Regex Library

libgnuregex is the regex subset of Gnulib, the GNU portability library. The regex subset offers an extension of the regex(3) API to allow more flexibility in the flavor of regular expressions. libgnuregex also enhances POSIX regular expressions with more features and shorthand, such as: - \b and \B (word boundary, not word boundary) - \s and \S ([[:space:]], [^[:space:]]) - \w and \W ([[:alnum:]], [^[:alnum:]]) - \` and \' (beginning of subject, end of subject)
