# NREX: Node RegEx
|
||
|
|
|
||
|
|
Small node-based regular expression library. It only does text pattern
|
||
|
|
matchhing, not replacement. To use add the files `nrex.hpp`, `nrex.cpp`
|
||
|
|
and `nrex_config.h` to your project and follow the example:
|
||
|
|
|
||
|
|
nrex regex;
|
||
|
|
regex.compile("^(fo+)bar$");
|
||
|
|
|
||
|
|
nrex_result captures[regex.capture_size()];
|
||
|
|
if (regex.match("foobar", captures))
|
||
|
|
{
|
||
|
|
std::cout << captures[0].start << std::endl;
|
||
|
|
std::cout << captures[0].length << std::endl;
|
||
|
|
}
|
||
|
|
|
||
|
|
More details about its use is documented in `nrex.hpp`
|
||
|
|
|
||
|
|
