This is transformed into - `new Name(..., ..., attributes())` - * Some function-like constructs are resolved (see `rebuildParsers.php` for a list) - -Building the parser -=================== - -Run `php grammar/rebuildParsers.php` to rebuild the parsers. Additional options: - - * The `KMYACC` environment variable can be used to specify an alternative `kmyacc` binary. - By default the `phpyacc` dev dependency will be used. To use the original `kmyacc`, you - need to compile [moriyoshi's fork](https://github.com/moriyoshi/kmyacc-forked). - * The `--debug` option enables emission of debug symbols and creates the `y.output` file. - * The `--keep-tmp-grammar` option preserves the preprocessed grammar file. |
