    Pxereg

    Pxereg (regexp inversed) is a little package allowing to generate all possible string from a regexp source string. The pxeger grammar does not follow exactly the regexp one, so some features may be missing, but it should cover most of use cases.

    Usage

    In node

    # npm install pxeger
    
    var Pxeger = require( 'pxeger' );
     
    console.log( Pxeger.reverse( 'fo{2,5}' ) );

    In browser

    Download pxeger.min.js somewhere then :

    console.log( Pxeger.reverse( 'fo{2,5}' ) );
    

    Unsupported feature

    These features cannot work with Pxereg :

    • * modifier, because it is not bounded, and would generate infinite strings
    • + modifier, for the same reason
    • {N,} modifier, for the same reason

    These features would be nice but are not implemented and may never be :

    • Backward references
    • [^N], I don't really see the point in this kind of library ?
    • [[:blank:]], it wouldn't be hard to do but I don't have the time right now

    Pull requests are welcome. If you wish to tweak the grammar, feel free to use my PEG.js online editor, which has been used to write this package.
