Hi @amezin :wave:

Could you provide instructions on how to reproduce your issue?

[amezin]

Just use the plugin without any package/plugin manager. https://github.com/z-shell/F-Sy-H/blob/main/docs/README.md#manual

Git subcommands (i.e. "checkout" in "git checkout") won't be highlighted. Zsh will fail to load any chroma/*.ch. Because only functions directory will be added to fpath, not the root directory.

Also experiencing this bug when loading F-Sy-H via zplug. Can confirm that switching to amezin/F-Sy-H@fix/chroma solves it.
