lwre — lightweight regular expression matching for C
lwre is a lightweight regular expression matching library
intended for those occasions when you want to search in text with a
minimum of fuss, bloat and complexity. Compared to other common
solutions it is ten times smaller than the POSIX regex(3) functions
and more than thirty-five times smaller than the popular PCRE package.
It has far fewer bells, whistles, dials and guages, but in return
offers the simplest possible interface, very reasonable performance,
and freedom from the exponential complexity that renders backtracking
implementations useless for certain kinds of regular expression.
A typical usage scenario might be:
struct re re= RE_INITIALISER("your regular expression here");
int nmatched= re_match(&re, your string to search here);
if (nmatched > 0) puts("found it!");
lwre supports UTF-8 encoded multibyte characters and submatch
recording, including within repetitions (creating multiple submatches
according to the number of times the repetition matches).
