ebnf tools

A collection of tools to work with ebnf grammars, like conversion between different formats, railroad generation and random example generation.

Getting Started

Prerequisites

Requires python3.9 or higher.

Other requirements like lark and railroad-diagrams should be installed automatically by pip

Installing

pip install ebnf

If you want to use one of the extra utils with extra requirements, use the ebnf[<extra>] syntax:

• railroad diagram generation: pip install ebnf[railroad]

Tools

The 'base' ebnf dialect for this package the one used by the lark package. All features should work for it, but might not work for others.

ebnf.railroad - railroad diagram generation

Generates a html file containing svg for each rule/terminal in the input grammar. Can take a lot of different options, check the help for more info

ebnf.convert - dialect translation (TODO)

Attempts to convert between different dialects, with the focus being generation lark compatible output

ebnf.example - generates an example for a grammar (TODO)
