Can chezmoi tell me the target path for a give source path?

[jdevera]

Is there some functionality where I can give it dot_local/share/exact_private_foo/file.ini.tmpl and get back .local/share/foo/file.ini?

Context: I wrote a file picker for my chezmoi repo but I don't trust my poor attempt at implementing prefix and extension removal logic.

Yes, use the target-path command for this.

Is this exposed in the templates? I can do {{ output "chezmoi "target-path" $foo | trim }}, but that launches a bunch of unnecessary chezmoi processes, which could be kinda slow on Windows 😒

[juliekoubova]

oh I can't, it takes an instance lock

[twpayne]

The target path is currently not available as a template variable. Can I ask what you need this for? (I'm trying to avoid the XY problem here).

[juliekoubova]

solved it with a regex, kinda clunky, but good enough for my use case

#!/bin/sh
command -v zsh >/dev/null || exit 0
exec zsh <<'EOF'
{{ define "compile" }}
# {{ . | include | sha256sum }}
zcompile {{ .
  | replaceAllRegex "dot_" "."
  | replaceAllRegex "\\.tmpl" ""
  | quote }}
{{ end }}

{{ template "compile" "dot_aliases.tmpl" }}
{{ template "compile" "dot_config/zsh/dot_zprofile" }}
{{ template "compile" "dot_config/zsh/dot_zshrc" }}
{{ template "compile" "dot_profile" }}
{{ template "compile" "dot_shrc" }}
{{ template "compile" "dot_zprofile" }}
EOF

That's a reasonable request, IMO. Not sure how easy it would be accomplish, but it wouldn't be a variable as much as a template function.

[jdevera]

Oh wow, that was so... "right there", I only used that command without parameters. Thanks!

[twpayne]

Thank you for providing the context for your question too. I've had to deal with too many instances of the XY problem recently, so having the context was very helpful in avoiding that.
