Packaging (simple) tools in Golang

Packaging (simple) tools in Golang

[Jelle Licht]

Hello Guix!

How would one package a tool written in Go(lang) using guix? I am
looking at https://github.com/guitmz/n26, but all of my efforts using
the go-build-system end up having only some documentation and (if I set
`#:install-source?' to #f) the sources in the resultant output. Ideally,
I would end up with a <out>/bin/n26 in addition to the documentation I
get now.

Thanks for pointers or clarifications!

To clarify, when you tell it not to install the source code, it installs
the source code anyways?

Can you share your package definition?

Yeah, I fumbled that up summarising it here; `#:install-source?' does
exactly what it says on the tin.

I figured it out, it was a problem with the `#:unpack-path' being
"github.com/guitmz/n26", yet the `#:import-path' needing to be
"github.com/guitmz/n26/cmd/n26". Cargo-culting saves the day yet again.

I'm not sure whether it works, as I don't have an account with this bank
to test it with, but it seems to at least build reproducibly on two of
my machines.

I'll clean it up and verify that it actually works before pushing it.
