cltk v0.1.0
cltk
This is a port of the Ruby Language Toolkit to the Crystal Programming Language.
CLTK (like RLTK) is: a collection of classes and methods designed to help programmers create languages in an easy to use and straightforward manner. This toolkit provides the following features:
- 2 Lexer generators based on PCRE Regexps from crystals STD Lib and a second faster one based on the crystal-dfa DFA automaton implementation
- Parser generator
- AST node baseclass
- Class for representing context free grammars
In addition, CLTK includes several ready-made lexers and parsers. As well as a serialization mechanism that renders a finalized parser back into crystal syntax to compile it without having to be finalized again at startup (see exp_lang_repl for a usage example).
To see what works have a look at the specs or run them with:
$ crystal spec
The Implementation has been strongly altered but the API is compatible to RLTK. The LLVM Bindings has not been ported. Instead crystals own LLVM Bindings were used in examples/kazoo/chapter 8/kcontractor.cr
Usage
To use the toolkit in your project add this to your application's shard.yml
