Conditional or optional files in contents

[clowder]

I'm looking to conditionally exclude a file from the contents list of a package. We use GoReleaser snapshot builds to set feature flags and need to install an extra configuration file only for those builds.

Initially, I hoped to template the type — e.g., type: {{ if .IsSnapshot }}deb{{ else }}ignore{{ end }} — but that attribute doesn't support templating. I also looked into templating the src attribute, but there doesn't appear to be a mechanism to skip missing files (rather than throwing an exception).

Is there a feature or workaround I've missed that would allow me to achieve this?

if I'm not mistaken if src is empty, the file is skipped, so you could probably template src instead
