NAME ^

Parse::Highlife - Perl extension for grammar based parsing and transformation of data.

SYNOPSIS ^

  use Parse::Highlife;
  
  # define grammar (grammar for DEC format as an example)
        my $grammar = q{
                space ignored: /\s\n\r\t+/;
                multiline-comment ignored: "/*" .. "*/";
                singleline-comment ignored: /\#[^\n\r]*/;
                file: { declaration 0..* };     
                        declaration: [ "@" identifier ] literal;
                                literal: < map string real number identifier >;
                                        map: [ symbol ] "[" { pair 0..* } "]";
                                                pair: [ symbol ":" ] declaration;
                                        string: < double-quoted-string single-quoted-string >;
                                                double-quoted-string: '"' .. '"';
                                                single-quoted-string: "'" .. "'";
                                        real: /\d+\.\d+/;
                                        number: /\d+/;
                                        identifier: symbol { "." symbol 0..* };
                                                symbol: /[\w\d]+(\-[\w\d]+)*/;
        };
  
        # setup compiler
        my $compiler = Parse::Highlife -> Compiler;
        $compiler->grammar( $Grammar );
        $compiler->toprule( -name => 'file' );
  
        # compile document
        $compiler -> compile( 'myfile.txt' );
