Developing Locally

Dependencies

In order to change the grammer and regenerate lexer/parser/etc:

• java
• antlr

For other development:

• python (3.13)
  • I suggest using pyenv to manage multiple python versions on your machine
• poetry - to manage virtual env
• Make - to help run useful commands

Updating and Debuging

Grammer is defined in txt2musicxml/grammer/Chords.g4. To generate antlr python classes (Lexer, Parser, Visitor, Listener) from the grammer file, run:

antlr4 -Dlanguage=Python3 txt2musicxml/grammer/Chords.g4 -visitor

Those classes are direct dependecies of the application, they must exist for the main program to run.
