Formatting Your ANTLR4 GrammarsThe antlr-format package provides a small library to format your ANTLR4 grammar in a wide variety of ways. It has a companion named antlr-format-cli which provides a terminal command for running the formatter in batch files and so on. You can read more about it in its own Readme.
Nothing special here, just use NPM (or any other package manager):
npm i antlr-format
Read the formatter documentation for further details and a code example.
Added missing type definition entry in package.json.
BREAKING CHANGE:
The package has been split into a cli wrapper and the actual formatter class. This avoids inclusion of otherwise unnecessary packages, when importing this package and works around a problem with esbuild when mixing ESM and CommonJS modules running in Node.js (for example using Jest with ts-jest).
Additionally, the GrammarFormatter class now accepts a string with the grammar content and does the tokenisation on its own. This avoids that you have to run the ANTLRv4 lexer manually (or even care for it at all).
This is the initial release of the package.
