Fregex - Yet another PCRE wrapper to fortran

This project aims to provide a good suport for Perl Compatible Regex just like other famous existing languages: Python, C, C++...

Example

program simple_example
    use fregex
    implicit none
    type(regex_t) :: re
    type(match_t) :: match

    character(:), allocatable :: string
    character(:), allocatable :: pattern

    ! Operations
    pattern = "(.+)([\+\-\*\/]{1})(.+)"
    string = "1/sin(x)"
    call re % compile(pattern)
    call re % match(string)
    if (size(re % matches) > 0) then
        match = re % matches(1) ! Gets the first match
        print*, "string: ", string
        print*, "pattern: ", pattern
        print*, "First Group: ",  match % groups(1) % content ! 1
        print*, "Second Group: ", match % groups(2) % content ! /
        print*, "Third Group: ",  match % groups(3) % content ! sin(x)
    end if
end program

Getting Started

FPM

This project supports the Fortran Package Manager. Follow the directions on that page to install FPM if you haven't already.

First get the code, by cloning the repo:

git clone https://github.com/14NGiestas/fregex.git
cd fregex/
fpm run simple_example

This will build the program and execute the simple_example.f90 at the app/ folder

Using as a dependency in FPM

Add a entry in the "dependencies" section of your project's fpm.toml

# fpm.toml
[ dependencies ]
fregex = { git = "https://github.com/14NGiestas/fregex.git" }
