Is anybody aware of a tool or script that can generate a first version of a prettier grammar (or language plugin) from an existing ANTLR, treesitter or Atom/Sublime/VScode grammar?

• https://github.com/SimplyDanny/modelica-language-vscode
• https://borischumichev.github.io/modelicaSublimeTextPackage/
• https://github.com/modelica-tools/modelica-mode
• Add a formal grammar using ANTLR modelica/ModelicaSpecification#2378
• Q: official grammar by MA OpenModelica/tree-sitter-modelica#25
