Good idea -- done! The goimports way is a bit more advanced and featureful too.
I love how all these little tools are basically just wrappers around a library package which does all the work, so you can reuse them in your own code. -Ben On Sun, Nov 25, 2018 at 8:53 AM Sameer Ajmani <sam...@golang.org> wrote: > Instead of writing your own logic to resolve missing imports, could you > run the goimports tool?
