x/tools/gopls: no folding ranges for invalid code

Not sure why this has happened however out of the blue Visual Studio Code is now unfolding all code every time the file is saved. I have tried uninstalling/reinstalling and removing extensions though nothing has worked.

All code is unfolded every single time the file is saved and results in a lot of lost time. I reported the issue in the Visual Studio Issue for Bugs and was told that the issue is with the Go Extension itself. Basically it appears that the Go Extension for VSCode is causing the code to unfold every time the code is saved. See what was said in the VSCode issues report below

I can reproduce.

From debugging I see that the go extension now also registers a folding range provider. However that provider doesn't work well with incomplete code. It then returns no folding ranges, what results in all folded ranges to go way. E.g. no ranges returned for that code:

package main w import ( "fmt" "io" "net/http"

"github.com/microsoft/vscode-remote-try-go/hello" )

func handle(w http.ResponseWriter, r *http.Request) { io.WriteString(w, hello.Hello()) } Can you file the issue against the go extension? https://github.com/golang/vscode-go Thanks a lot!
