Problem

I like using eza --tree, but I'm extremely mildly inconvenienced by things like cargo target directories:

tether@Gasoline-Veins ~/D/testasdf> eza --tree
.
├── Cargo.lock
├── Cargo.toml
├── shell.nix

I already use --git-ignore in my alias, but sometimes there isn't a .gitignore file. So i would like a way to ignore directories which contain CACHEDIR.TAG.

Solution

add an argument, perhaps named --cachedir-ignore, which causes eza to ignore directories which meet the Cache Directory Tagging Specification. I'll poke around in eza today and might do it.

Stretch Goal

add an argument, or extend --ignore-glob to support hiding directories which contain a specific file (e.g., a tool which doesn't add CACHEDIR.TAG, but has some other uniquely-named file in it's cache directory)
