4 years ago The issue you're running into is that | is a pipeline operator, not an "or" operator. Piping a value into a function like this uses the value as the final argument to the function. So what's actually happening in your example is eq .chezmoi.hostname "foo" gets evaluated to a boolean (let's say true for example), then eq .chezmoi.hostname "bar" true gets evaluated. But since true can't be compared to a string with eq, it throws the error you're seeing.
Having said that, there is an easy way to achieve what you're trying to do. The eq function can actually take several arguments, not just two. The function will return true if the first argument compares equal to any of the remaining arguments. So you can just do this:
{{- if eq .chezmoi.hostname "foo" "bar"}}
Config for foo and bar
{{- end }}For example:
$ echo '{{ if eq "foo" "foo" "bar" }}hello{{end}}' | chezmoi execute-template
hello
$ echo '{{ if eq "bar" "foo" "bar" }}hello{{end}}' | chezmoi execute-template
hello
$ echo '{{ if eq "baz" "foo" "bar" }}hello{{end}}' | chezmoi execute-template
chezmoi does use the text/template engine, so everything on the linked page should work as expected. Are you seeing any other issues that don't seem to work? In addition to that, chezmoi also bundles all of the Sprig functions described here, so you can use any of them in your templates too.

I'm not sure if this is a feature request or a bug, because I believe at some point this worked in chezmoi.
When I create templates in chezmoi, it's mostly to change configs slightly for different systems based on the hostname. If I have the same changes I want to have on the systems foo and bar, I would like to say: {{- if eq .chezmoi.hostname "foo" | eq .chezmoi.hostname "bar"}} Config for foo and bar {{- end }} When I do chezmoi apply, it says
<eq .chezmoi.hostname "bar">: error calling eq: incompatible types for comparisonIt would be nice if most of the things higlighted in this webpage would work in chezmoi templates.
