Question about approximate matching

[georgekola]

I am trying to do just approximate matching of a small string in a given larger string and return if there is a match based on the specified maximum error/cost.

I found tre-agrep and the code I wrote based on the docs works fine. Thanks for making this open-source library.

I do not need any regular expression support -- I want to know if there is a way to optimize the call to int tre_regncomp(regex_t *preg, const char *regex, size_t len, int cflags) ? I would like to do it for two reasons 1. Performance (the code is on the critical path ) 2. I take arbitrary input and do matching and I am not escaping the search string (Escaping would further slow things down and I do not know how to correctly do it). Some pointers to which functions I should call/modify to accomplish what I want would be greatly appreciated.

Thanks, George
