The bug manifests itself when a non-existent file is passed in as an argument to gopls, causing a nil pointer dereference panic. This is due to an attempt to reference the "mapper" attribute, which is not set if the file is not found. The resolution is to check for an informative error that is set on the file instance after "getFile" is called and return it immediately to the caller to allow the error to propagate up to the main() function and print the error to stdout. Testing: -------- Non-existent file: $ gopls -rpc.trace -v check gopls/doesnotexist.go check: file:///Users/albertteoh/repo/tools/gopls/doesnotexist.go: open /Users/albertteoh/repo/tools/gopls/doesnotexist.go: no such file or directory Existing go file: $ gopls -rpc.trace -v check internal/lsp/definition.go 2019/08/03 13:33:00 Info:go/packages.Load packages = 2 2019/08/03 13:33:00 Info:go/packages.Load package = golang.org/x/tools/internal/lsp ...

Go Tools
This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc and vet for example, are included in binary Go
distributions.
Others, including the Go guru and the test coverage tool, can be fetched with
go get.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
Download/Install
The easiest way to install is to run go get -u golang.org/x/tools/.... You can
also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
