I’ll add some small questions in this thread. I’m debuting in Go and I’m learning from some projects as well as hugo.
Here: [https://github.com/spf13/hugo/blob/master/transform/hugogeneratorinject.go](https://github.com/spf13/hugo/blob/master/transform/hugogeneratorinject.go)
I believe this if serves no purpose and could be removed:
`if len(newcontent) == len(ct.Content()) { head := "" replace := []byte(fmt.Sprintf("%s\n\t%s", head, hugoGeneratorTag)) newcontent = bytes.Replace(ct.Content(), []byte(head), replace, 1) }`

No, it serves a perfectly fine purpose, otherwise, it would have been long time removed.
We welcome new contributors and this is in general a very helpful crowd. But you ask some very basic questions that I feel is better suited for a more general developer forum, or maybe you should read some “Go programmers guides” or similar.

Thanks. I explored hugogeneratorinject\_test.go, ran it and I see what I missed.
There are still some concepts I don’t fully understand.
I’ll read more.
