[go-nuts] extract VCS branch name used during build

Hi, I would like to be able to extract the VCS branch name used during build. Currently I append "-X main.BranchName=${BRANCH}" to the build line which works, but I was hoping there might be a cunning way to extract this from runtime/debug? Thanks, -Steve -- You received this message becaus

Re: [go-nuts] extract VCS branch name used during build

You can use go:generate and go:embed to achieve this. In our CI/CD pipeline we generate a json file with a lot of information like vcs, branch, tag, date and time, hash and a lot more. Then we embed this json into the binary. I became aware of this technique from https://levelup.gitconnected.com/a

Re: [go-nuts] how to get the json line number when getting unmarshal errors?

The best method I've found is to wrap the input reader in something that keeps track of lines. You can then type-assert the errors to one of the exported error types in the json package to get the offset the error occured and translate it into line numbers using your wrapper. I have a package for s
