It provides: \ * Regular expressions or literal strings as \ terminals (tokens), \ * Multiple (non-contiguous) productions for any rule, \ * Repeated, optional and alternate subrules within \ productions, \ * Late-bound (run-time dispatched) subrules \ * Full access to Perl within actions specified as \ part of the grammar, \ * Simple automated error reporting during parser \ generation and parsing, \ * The ability to commit to, uncommit to, or reject \ particular productions during a parse, \ * Incremental extension of the parsing grammar (even \ during a parse), \ * Precompilation of parser objects, \ * User-definable reduce-reduce conflict resolution \ via "scoring" of matching productions. \ See the file "RecDescent.pod" for excruciating \ detail on all of this. checksums md5 e91351ad179a3843fbe8e521b135acaf \ sha1 bec47f6a011b1c2dd1175b15c106fbdd51cbcd55 \ rmd160 64bacbb5811836c0535bb1fa0dcb52c8b66907c7 platforms darwin if {${perl5.major} != ""} { depends_lib-append port:p${perl5.major}-version supported_archs noarch }
