Similar to godef, gosym prints the location of the definition of the symbol in the Go source code.

It is based on go/types and golang.org/x/tools/go/loader, so it does not have the known limitations of godef. It uses go/build to find Go source code files with the correct GOOS and GOARCH.

The minimal go version is go1.5, since gosym uses the go/types in the standard library.

To build,

go get github.com/zncoder/gosym

For example, to find the definition of the symbol at position 100 in the file foo.go,

gosym -f foo.go -o 100

You can replace godef with gosym by symbolic linking gosym to godef. This should work with go-mode.el in Emacs.

Gosym is slower than godef because of the use of loader.
