Command gopathexec executes program with arguments, while expanding $GOPATH with multiple workspaces into multiple arguments.
Usage: gopathexec program [args]
It is helpful for writing go generate directives for programs that do not understand import paths, but you need to specify include paths that are other Go package folders.
For example, consider a go generate directive like this:
//go:generate protoc -I$GOPATH/src/github.com/gogo/protobuf/protobuf --go_out=. sample.proto
That will only work if your GOPATH env var happens to contain one workspace. By prepending the above command with gopathexec:
//go:generate gopathexec protoc -I$GOPATH/src/github.com/gogo/protobuf/protobuf --go_out=. sample.proto
It will effectively execute:
protoc -I/workspace1/src/github.com/gogo/protobuf/protobuf -I/workspace2/src/github.com/gogo/protobuf/protobuf --go_out=. sample.proto
If you have 1 or no GOPATH workspaces, gopathexec executes the given program and arguments without modification.
