Frack

A fake Rust error generator - both CLI and as a lib! Can be used for joke errors or, if you desire, real ones.

The goal is to be as accurate to real rustc errors/warnings as possible. If I'm missing the mark, please make an issue or a PR.

CLI

See frack help.

Command for the image:

frack
    error AMOGUS
        "this code is sus" \
        "    let Foo { x } = z;" \
        8-16 \
    fix "`y` lives matter" \
        "    let Foo { x, y } = z;" \
        15-17 \
    help "don't discriminate next time" \
    note "error generated by Kyllingene/frack"

Lib

See files in examples/: they're small and easy-to-read. To try them out, do cargo run --example NAME, e.g. cargo run --example demo.
