Can't format hidden / dotfiles

[declension]

Describe the bug

Can't get yamlfmt (and probably other formatters) to process "hidden" / "dotfiles", i.e. files with a leading ..

This is particularly annoying for certain CI systems, where the primary configuration is in YAML with names like .gitlab-ci.yml.

To Reproduce

• Configure a project with treefmt-nix
• Configure with programs.yamlfmt.enable = true
• Add a slightly malformed YAML file, test.yaml and a copy at .test.yaml
• nix fmt

Expected behavior

Both are formatted

But only one is...

Additional

Have tried various combinations of global and per-formatter include / exclude overrides, but no joy!

[declension]

Can also replicate this with recent treefmt-nix on other formatters e.g. shfmt, so widening the title

Ah, so maybe this is just a downstream effect of numtide/treefmt#153

What version of treefmt are you using?

[declension]

What version of treefmt are you using?

Yes, I started to wonder about this too. A few different versions in a few places, but generally pinning to nixpkgs 24.05, and pinning treefmt's inputs to that. So then 0.6.1 I think.

[brianmcgee]

You want to use treefmt2 instead.

If you use treefmt-nix it will automatically use the latest version. treefmt is pointing to the old rust branch and is kept for posterity until version stabilises at which point we'll update it (quite soon I think). treefmt2 points to the latest version which was re-written in Go.

This appears to be an issue for hidden justfiles, .justfile, too. I think this is related to the just formatter in this case. I've opened #246 to fix this.
