Failing a build from template function

dev

Looking at https://github.com/gohugoio/hugo/issues/3817, I’m thinking about doing something along the lines of:

func (ns *Namespace) Errorf(format string, a ...interface{}) string {
    jww.ERROR.Printf(format, a...)
    // fail build somehow here
}

However, I’m unsure how to best go about killing the build process. The thought of panic() crossed my mind, but I’m not confident that’s the correct solution.

Also, are there nuances I should be wary of? Something that jumps to mind would be perhaps a template tag cache which could interfere with the intended effect.

I will comment on the issue.
