+# DParser
+###### (you know... 'da parser)
+
+
+## Introduction
+
+`DParser` is a simple but powerful tool for parsing.  You
+can specify the form of the text to be parsed using a combination of
+regular expressions and grammar productions.  Because of the
+parsing technique (technically a scannerless GLR parser based on the
+Tomita algorithm) there are no restrictions.  The grammar can be
+ambiguous, right or left recursive, have any number of null
+productions,
+and because there is no separate tokenizer, can include whitespace in
+terminals and have terminals which are prefixes of other terminals.
+`DParser` handles not just well formed computer languages and data
+files, but just about any wacky situation that occurs in the real world.
+The result is natural grammars and powerful parsing.
+
+
+## Features
+
+* Powerful GLR parsing
+* Simple EBNF-style grammars and regular expression terminals
+* State-specific symbol table
+* Priorities and associativities for token and rules
+* Built-in error recovery
+* Can be compiled to work with or without the Boehm garbage collector
+* Speculative actions (for semantic disambiguation)
+* Auto-building of parse tree (optionally)
+* Final actions as you go, or on the complete parse tree
+* Tree walkers and default actions (multi-pass compilation support)
+* Symbol table built for ambiguous parsing
+* Partial parses, recursive parsing, parsing starting with any non-terminal
+* Whitespace can be specified as a subgrammar
+* External (C call interface) tokenizers and terminal scanners
+* Good asymptotic efficiency
+* Comes with ANSI-C, Python and Verilog grammars
+* Comes with full source
+* Portable C for easy compilation and linking
+* BSD licence, so you can include it in your application without worrying about licensing
+
+
+## Example Grammars
+
+* [ANSI-C](ansic/ansic.g)
+* [Python](tests/python.test.g)
+* [Verilog](verilog/verilog.g)
+
+
+## Documentation
+* [Man page for parser generator](make_dparser.cat)
+* [Manual](docs/manual.md)
+* [FAQ](docs/faq.md)
+
+
+## Public Headers
+
+* [dparse.h](dparse.h) - main parser data structures and functions
+* [dparse_tables.h](dparse_tables.h) - parse tables data structures
+* [dsymtab.h](dsymtab.h) - optional symbol table
+
+
+## Building
+
+* To build: `gmake` -- only available with source code package
+* To test: `gmake test` -- only available with source code package
+* To install: `gmake install` -- binary or source code packages
+
+For python support: `cd python; gmake install`
+
+
+## Makefile Options
+
+* `D_USE_GC`: set to 1 to use the Boehm garbage collector
+* `D_DEBUG`: set to 1 to compile with debugging support (`-g`)
+* `D_OPTIMIZE`: set to 1 to compile with optimizations (`-O3`)
+* `D_PROFILE`: set to 1 to compile with profiling support (`-pg`)
+* `D_LEAK_DETECT`: set to 1 to compile with memory leak detection (`-lleak`)
+* `D_USE_FREELISTS`: set to 1 to use free lists instead of straign free/malloc (defaults to 1)
