Implement something like helm's include function

[cwrau]

I'm trying to get the major version of my chart and I've tried the following;

{{ regexReplaceAllLiteral "^(\d+)\.\d+\.\d+$" (template "chart.version" .) "${1}" }}

resulting in;

Error generating gotemplates for chart .: template: .:19: invalid syntax

{{ regexReplaceAllLiteral "^(\d+)\.\d+\.\d+$" (include "chart.version" .) "${1}" }}

resulting in the same error.

Trying to narrow it down I tried;

{{- $version := template "chart.version" . }}

resulting in;

Error generating gotemplates for chart .: template: .:19: unexpected <template> in command

At last I tried;

{{- $version := include "chart.version" . }}

resulting in;

Error generating gotemplates for chart .: template: .:19: function "include" not defined

How can we work with the templates you supply us?

I'm actually confused why you added sprig if we have nothing to use it with? Therefore I'm also thinking that I might have missed something 😅
