configure host tags (labels, groups)

[dpprdan]

Does chezmoi support configuring host tags (a.k.a. labels, groups)?

Essentially I would like to do something like:

data:
    tags: [work, wsl]

{{ if in .tags "work" }}
# code for all hosts with the tag "work"
{{ end }}
{{ if in .tags "wsl" }}
# code for all hosts with the tag "wsl"
{{ end }}
{{ if (and (in .tags "work") (in .tags "wsl")) }}
# code for all hosts with the tags "work" and "wsl"
{{ end }}

I haven't been able to find anything to that effect in the docs (or issues/discussion).

A simple use case would be more than one "work" host. The docs mention in an example to use hostname to capture machine-specific differences. But (IMHO) we often do not want to distiguish between specific machines or hosts but groups or types of hosts. E.g. if eq .chezmoi.hostname "work-laptop" will not work on a new-work-laptop that you want to provision, while still using work-laptop.

I use boolean flags for each tag.

If you want to use an array of tags then you can use the has template function:

{{ if has "work" .tags }}
# code for all hosts with the tag "work"
{{ end }}

Awesome, thanks!

For those reading this and wondering what the syntax to negate a tag is:

{{ if not (has "work" .tags) }}
# code for all hosts without the tag "work"
{{ end }}

@twpayne Arrays aren't supported by any prompt[String|Choice]* functions, are they?

[twpayne]

No. But if you want to read an array, you can read a string and then call splitList.

@dpprdan For what it's worth, we added promptMultichoice{,Once} earlier this year.
