@ -2,16 +2,20 @@ SLRE: Super Light Regular Expression library
============================================
SLRE is an ISO C library that implements a subset of Perl regular
expression syntax. Main focus of SLRE is small size, [simple
API](https://github.com/cesanta/slre/blob/master/slre.h), clarity of code
and extensibility. It is making it perfect for tasks like parsing network
requests, configuration files, user input, etc, when libraries like
[PCRE](http://pcre.org) are too heavyweight for the given task. Developers in
embedded would benefit most.
expression syntax. Main features of SLRE are:
Extensibility is another great aspect of SLRE. For example, if one wants to
introduce a new metacharacter, '\i', meaning 'IPv4 address', it is easy to do
so with SLRE.
* Written in strict ISO C, conforming to ANSI C'89
* Small size (compiled x86 code is about 4kB)
* Uses no dynamic memory allocation and small stack space
* [Simple API](https://github.com/cesanta/slre/blob/master/slre.h)
* Implements most useful subset of Perl regex syntax (see below)
* Easily extensible. For example, if one wants to introduce a new
metacharacter `\i`, meaning "IPv4 address", it is easy to do so with SLRE.
