Integrating external sources into git repo rather than at runtime?

[stonewalljones]

I'd like to be able to use chezmoi to incorporate single files from eternal git repos (i.e. https://github.com/grml/grml-etc-core/blob/master/etc/zsh/zshrc and https://github.com/gpakosz/.tmux/blob/master/.tmux.conf). I'd like these files fully in the repo so the current .chezmoiexternal functionality doesn't looks like it fits my need and since I want to just pull the single files it doesn't look like git submodules would work either.

Is what I've described possible with chezmoi currently?

Yes, you can use externals with GitHub's "raw" URLs, for example:

[".zshrc"]
    type = "file"
    url = "https://raw.githubusercontent.com/grml/grml-etc-core/refs/heads/master/etc/zsh/zshrc"
    refreshPeriod = "168h"

[stonewalljones]

Right but those are pulled in at runtime and not committed to the internal git repo correct?

[twpayne]

That's correct.

I'm looking for a way to pull in single files from external sources ,commit them to the repo, and keep them up date.

[twpayne]

You can use a script or a hook for this.

Why? What problem are you trying to solve?

If you’re looking for an aperiodic update of files used, consider using the new file external support added for #4090 to support fully offline updates.

Sounds like what you're describing is using git submodule to 'include' sources from another git repo.
chezmoi's method of externals is much more versatile as it allows more nuanced control over what is imported vs git's all-or-nothing approach, especially if you're using archive file which allows extracting only what is relevant to you.
