gopls compatability

[slnt]

I am using the latest version of:

• Atom v1.13.1 x64
• ide-go v0.12.3
• atom-ide-ui
  - [ ] go-langserver

Operating System:

macOS 10.14.3

Expected Behavior

Expected it to JustWork™ when setting the server path to ~/go/bin/gopls, as it does for when using bingo. Since bingo is no longer going to be maintained in favour of gopls the ide-go package should work with the official language server.

Actual Behavior

A gopls process is spawned, but Atom does not communicate with it from what I can tell.

Steps to Reproduce

go get -u golang.org/x/tools/cmd/gopls

Set custom server path to $(which gopls)

Reload window, check for process with ps aux | grep gopls to see process.

See that atom-ide-ui displays nothing, format on save doesn't work, etc.

It seems to work using @saibing's version of gopls, however there are a lot of... interesting issues with it it seems. Go module support seems rather lacking at the moment.

I doubt there is anything to do here for this package, except maybe make gopls the first class supported citizen rather than go-languageserver.

Reopening this as gopls seems to work as intended with VSCode, however the ide-go package does not handle it.

Generally the issues I see are ending up with a lot of "Type X is undeclared" for type outside of whatever file I'm currently working in, even though Type X is in the same package.

Imports are also a bit funky.

I agree that it would be preferable for this plugin to switch to gopls since it is still in active development and supports go modules, as described here
