fortran_pcre

============

A very basic wrapper around the PCRE regex C library. Use at your own

risk! MIT licence.

This contains the absolute bare minimum to be the least bit useful:

- `pcre_compile`: to compile a regex

- `pcre_exec`: to match a regex

- `pcre_fullinfo`: to get info on a match

- a bunch of constants to pass to `pcre_fullinfo`

`test.f90` is basically a minimal port of `pcredemo.c`

`test3.f90` runs a whole bunch of regex tests

- Compile test like: `gfortran-7 -g -std=f2008 pcre_constants.f90 pcre_module.f90 test3.f90 -o test3 -lpcre`

Requirements

------------

- libpcre1

- Fortran compiler with decent F2008 support

    - Tested with gfortran 5.4.1, 6.2.1, 7.0.1

Bugs/gotchas

------------

- ~~some character classes like `\s` and `\d` don't work. No idea why.~~ **Fixed**

- super minimal functionality at the mo

TODO

----

- [ ] add module for passing strings between C/Fortran

- [x] add the rest of the constants/hex flags

- [x] move constants into separate module

- [x] add tests!

- [ ] make object-oriented?

- [ ] add CMake support
