How i can add regex filter in if construction?

[jidckii]

I want to upload postfix releases to a special directory, but I can't figure out the right condition for this. Can you suggest how to do it?

I tryed this

folder: '{{- if .IsNightly }}nightly/{{.Version}}{{- else if filter .Version "v\d+\.\d+\.\d+-(dev|alpha|beta|rc)\d*" }}beta/{{.Version}}{{else}}{{.Version}}{{- end }}'

but, has error

error=template: tmpl:1: invalid syntax

Hey, there is no filter function, but in this case you can simply check if .Prerelease field is set, e.g.:

folder: '{{- if .IsNightly }}nightly/{{.Version}}{{- else if .PreRelease }}beta/{{.Version}}{{else}}{{.Version}}{{- end }}'

correction: there is the a filter function indeed, I forgot about it... not sure why its not working in your case, though, will check.

Original answer should still be a valid/simpler alternative though

it looks like your regex is not valid, not sure why though, maybe needs more escaping due to templates...
