About:
erlfmt is an automated code formatter for Erlang that enforces a consistent coding style across projects. It parses Erlang code into an Abstract Syntax Tree (AST) and reformats it based on a configurable set of rules. This eliminates debates over formatting and improves code readability and maintainability.
Key Features:
  • AST-based formatting for robustness
  • Configurable formatting rules
  • Support for comments and complex expressions
  • Integration with CI pipelines and editors
Use Cases:
  • Enforcing consistent code style across large Erlang codebases
  • Automated formatting during CI/CD builds
  • Pre-commit hooks to maintain clean diffs
Alternatives:
  • erlang-formatter – An older formatter that may use regex-based approaches, whereas erlfmt uses AST for greater accuracy.
