A JavaScript mangler/compressor for MoonBit, built for the MoonBit JS backend.

This repository is a MoonBit workspace with two modules:

• minifier/ — the moonbit-community/evol-minifier library: parse modern JavaScript, resolve scopes, rename local identifiers, and print minimal equivalent output.
• evol/ — the moonbit-community/evol command-line program: read a file (or stdin) and write the minified result.

The CLI exits with a nonzero status on input or argument errors. --help and --version exit successfully.

CLI options

• --top: preserve top-level binding names while renaming local bindings.
• --output <path>: write to the specified file; use - for stdout. When omitted or empty, path/to/file.js produces path/to/file.min.js. Stdin input requires an explicit output destination.
