AGL: A Grammar Language (or maybe Akehurst Grammar Language!)

Generic Language (DSL) support for kotlin multiplatform (parser, syntax-analyser, formatter, processor, etc)

There are many parser technologies, frameworks, generators, libraries that already exist. When I first started this one in about 2007 there was none that met all the requirements that I have. It has taken me several years (too many) to finally reach the stage where I am happy to publish it. (mostly because it was a home project and not worked on very frequently until the last couple of years, 2017/2018).

My Requirements:

• Simple grammar for defining a language with no restrictions -- i.e. should support left & right recursive rules,
• Useable in Java and Javascript (other platforms/languages a bonus but not essential)
• No need to worry about keyword/identifier clashes
• Interpreted at runtime, i.e. no generate parser step.
• Supports families of languages, i.e. grammar composition/extension

Other

• Editor Integration and Demo

Articles

• Creating a custom Domain Specific Language for text input validation
• Documentation

TODO

lots:

• performance improvements
• PT is not always what one expects

Build

There are currently a number of failing tests, these indicate things to be fixed, and desired performance improvements. To build locally the latest version, use assemble or publishToMavenLocal.
