gopls does offer autocompletion for unimported packages that are available in your module cache ($GOPATH/pkg/mod). I'm not aware of any features in GOPATH mode that would provide completions for packages you have not downloaded yet.

If you can share a specific example of this issue, please do so. Please also take a look at our troubleshooting guide and attach your gopls logs.

gopls now works well, and this issue is not reporting a bug.

When I take response to many projects, and now I want to start a new project.

In the past using GOPATH, starting a new project is just convenient because all packages can be well completed by gopls because all these normal packages're already in GOPATH as old project have downloaded them and share them.

Now using GOMODULE, even if I've hold many existed projects, when I start a new app project, I still need to consider which package I should go get first and then I can using gopls to auto completed its dot tip. I hope there exists a scheme that gopls can make-up a package that I use it in my new project in the first time(that it's just not go get yet), it can privilagedly refer to a package's newest version locally.

For example:
I own app1, app2 ,app3, app4 four projects and have built a big enough GOPATH/pkg/mod/....., they contains gin

GOPATH/pkg/mod/github.com/gin-gonic/gin@v1.1.0
GOPATH/pkg/mod/github.com/gin-gonic/gin@v1.2.0
GOPATH/pkg/mod/github.com/gin-gonic/gin@v1.3.0
GOPATH/pkg/mod/github.com/gin-gonic/gin@v1.4.0

then, I want to start a new app5. At the first moment,

• the go.mod is empty.
• Go111module is on.
• I havent run go get github.com/gin-gonic/gin in app5 yet

Then I press gin.

At this time , gopls should refer to existed versions of gin where old existed projects just fullfill it. They're:

GOPATH/pkg/mod/github.com/gin-gonic/gin@v1.1.0
GOPATH/pkg/mod/github.com/gin-gonic/gin@v1.2.0
GOPATH/pkg/mod/github.com/gin-gonic/gin@v1.3.0
GOPATH/pkg/mod/github.com/gin-gonic/gin@v1.4.0

Gopls counts a latest version of gin and then choose v1.4.0 to finish its dot tip completion.

Then I got tip:

gin.
      |.New()
      |.Default()
      |.....

Emmm, I've asked my mates this situation. They ask me back:

How auto-completion knows which version of gin to pick?

Should this supported by IDE not go chain?

I'm also comfused of this!

This workflow already exists in gopls--it is what we refer to as unimported completions. Can you please try this out and share a log if it doesn't work as expected?

Closing this issue as there hasn't been any activity on it for 2 weeks. Please file a new issue if unimported completions do not work for you.
