Dunnart D Parser Generator (ddpg) ================================= Enhanced LALR(1) Parser Generator for the D Programming Language. This (ddgp) tool is an implementation in D of the LALR(1) parser generators described in "Compilers - Principles, Techniques and Tools" (Aho, Sethi and Ullman, 1986) (aka the red dragon book) with modifications to allow conflict resolution using boolean predicates and a built in lexical analyser. It produces a single D file as output. The [specification language](https://github.com/pwil3058/dunnart/wiki/Specification-Language) for dunnart (in itself) is described (in the specification language for dunnart) in the file dunnart.ddgs which was used to implement the ddpg program recursively via a three stage bootstrap process (one stage now permanently retired). Building ddgp ============= To build __ddgp__ execute the following: ``` $ make ``` in the base directory. Synopsis ======== ``` ddgp [] Options: -f|--force: overwrite existing output file -m | --module=: insert a "module" statement in the output file using name -v | --verbose: produce a full description of the grammar generated -o | --output= | --prefix=: if using a path name based on the module name prefix it with path -e | --expect=: expect exactly "number" total conflicts -s | --states=: write a textual description of the parser's states to "path" to assist in resolution of any conflicts ``` Output File Name ================ If the _--module_ option is used the output filename will be derived from the module name (prefixed with the argument to the _--prefix_ option if present) unless it is overruled by the _--output_ option. If neither the _--module_ nor _--output_ option are present, the output filename will be constructed by replacing the input filename's suffix with "d". In no event, will an existing file be overwritten unless the _--force_ option is used. License ======= Dunnart D Parser Generator (ddpg) is licensed under the Boost Software License, Version 1.0.
