rust-spitter

A universal code minifier that supports multiple programming languages. This tool finds all relevant source files in a directory, minifies them, and outputs them in a standardized format.

Originally built to create a contiguous block of code from a project that could be used in graphical and art applications. PRs are welcome.

CAUTION: This is for display purposes only. This tool will not produce functioning code due to the fact it removes spaces, line breaks, etc. entirely.

Basic Usage

cargo run -- <directory> --lang <language> [--skip dir1,dir2,dir3]
