Library Dependencies in Go

Question

I created a library / package in Go, and the consensus was that only applications include a vendorfolder in their project, and libraries do not.

So now I included my package in another project ( govendor'ed), and everything worked fine until it got to Jenkins, and that was to use my local resources, where 2 of the dependencies were missing.

My readme file says that all you need to do is go getmy project, and you're done . But this is not the case if you use govendoring.

What should be the approach to my library? Can this be solved, or is this “problem” something that the end user must solve because they are using govendor?

Answer 1

It is rather a matter of opinion, I think, but I will share what I use.

I use git subtree to sell subreposites in my tree, then add a line //go:generateto update it later, for example

➜ git subtree add --prefix vendor/xxx/yyy/zzz https://github.com/xxx/yyy/zzz master --squash

Then add //go:generate git subtree pull --prefix vendor/xxx/yyy/zzz https://github.com/xxx/yyy/zzz master --squashlibraries to one of my files.

And just run go generateit before I release.

This is a solution to the issue with the release without the need for any external tools.
