# coretilus


</div>

**coretilus** is a parody of GNU Coreutils — a playful collection of typo-triggered command-line tools written in Rust like https://github.com/uutils/coreutils

Whenever you mistype something like `git` → `gti` or `grep` → `grpe`, coretilus answers instead of complaining.
Each binary is intentionally useless, funny, or just delightfully absurd.

## 🔁 What does “tilus” mean?

> **t.i.l.u.s. = Tilus Is Ludicrously Useless Stuff**

* A recursive acronym (because of course it is).
* It reflects the project’s spirit — *ridiculously, gloriously pointless utilities.*
* It's also `utils` with a typo.

cargo llvm-cov --doctests --open
```

## 📘 Generate docs

cargo doc --no-deps --open
```

## Generate gifs

First, we need to compile then we use https://github.com/charmbracelet/vhs

```bash
RUSTFLAGS="-C target-feature=+crt-static" cargo build --release
docker run --rm -v `pwd`/gifs:/vhs/output -v `pwd`:/src:ro -v `pwd`/target/release:/usr/local/bin ghcr.io/charmbracelet/vhs /src/coretilus.tape
for COMMAND in $(ls -d src/commands/*/ | xargs -n1 basename)
do
docker run --rm -v `pwd`/gifs:/vhs/output -v `pwd`/src:/src:ro -v `pwd`/target/release:/usr/local/bin ghcr.io/charmbracelet/vhs /src/commands/${COMMAND}/${COMMAND}.tape
done
```
### Optimize gifs is needed

```
gifsicle -O3 --colors 256 <heavy_gif>gif -o <light_gif>.gif
```
