I've modified gno version so that the output is like the one you proposed in this issue #3005. The output is in this format [branch].[N]+[hash] or [tag] for when there is a specific tag pointing to the commit. Is this what you expect from the gno version command? @thehowl

A few notes:

• Instead of having this in cmd/gno, make a package gnovm/pkg/version, with var Version = "develop"
  • This will default to "develop" as a version, when somebody uses go install / go build directly.
  • It also allows us to eventually have this as gnoland version, too.
• The ldflag should also go in the goreleaser set up: .github/goreleaser.yml

Marking draft for now while we wait for changes; put back into ready for review when changes are applied.

if I understand correctly, I create the version package in gnovm/pkg/version and only add the command in /cmd/gno/main.go ? @thehowl

if I understand correctly, I create the version package in gnovm/pkg/version and only add the command in /cmd/gno/main.go ?

yes (though it likely needs a new file in cmd/gno, like most commands)

[kazai777]

I've modified the implementation of gno version command, so that the version is develop in the case of installation via go build/go install by creating a version package with a develop version by default.

Installation with the Makefile

Installation with go build/go install

Hey @kazai777, can you fix the conflicts here? I've pinged @thehowl to take a look.
