Having issues with getting values from chezmoi in templates

[triallax]

What exactly are you trying to do?

Trying to write a template for a configuration file which has different locations on different systems. I have a file in .chezmoitemplates; let's call it file.toml. Here are the file's contents (I've removed all unnecessary details):

[foo]
bar = "{{ chezmoi.homeDir }}"

I then have the actual config file with the following content:

{{- template "file.toml" }}

The issue is that {{ chezmoi.homeDir }} doesn't work, giving me the following error:

chezmoi: template: file.toml:2:18: executing "file.toml" at <.chezmoi.homeDir>: nil data; no entry for key "chezmoi"

What have you tried so far?

Running chezmoi execute-template "{{ .chezmoi.homeDir }}" works just fine.

Where else have you checked for solutions?

• I have read chezmoi's how-to guide, and not found the answer.
• I have read chezmoi's FAQ, and not found the answer.
• I have searched chezmoi's reference guide, and not found the answer.
• I searched in the issue tracker and found nothing similar.

Output of any commands you've tried with --verbose

$ chezmoi apply --verbose
chezmoi: template: file.toml:2:18: executing "file.toml" at <.chezmoi.homeDir>: nil data; no entry for key "chezmoi"

When a template gets executed with {{ template "name" }}, it will be executed with nil data unless you explicitly provide some other value. (See here in the docs for Go's text/template feature for more details).

You should be able to fix it by explicitly passing . in instead:

{{- template "file.toml" . }}

I haven't actually tested this myself because when I tried I got some very weird errors trying to add a new template in .chezmoitemplates. (I'll file a separate issue about that if I can't track it down). But I'm pretty sure it'll work 😄

Thanks for the help! I'm away from the machine with the error right now, so I'll be keeping this open till I confirm that everything works. I was following https://www.chezmoi.io/docs/how-to/#handle-different-file-locations-on-different-systems-with-the-same-contents, which does not include the explicit passing of . you noted. Maybe I'll open a PR to update that part.

@zb140 that seems to have done the trick. Thanks again!
