Doesn't work with multiple proto files.

[Travis Cline]

The cli doesn't pass multiple proto files if provided and then each generated file contains an htmlstringer definition (among others).

[Walter Schulze]

You mean multiple proto files in the same package is a problem, because of conflicting htmlstringer functions?

[Travis Cline]

Correct.

[Walter Schulze]

The generated has changed a bit in the mean time.
Lets look at this file for example:
https://github.com/gogo/letmegrpc/blob/master/test/grpc.letmegrpc.go

You can now inject your own htmlstringer instead of setting a global variable.

func Serve(httpAddr, grpcAddr string, stringer func(req, resp interface{}) ([]byte, error), opts ...google_golang_org_grpc.DialOption) {
    conn, err := google_golang_org_grpc.Dial(grpcAddr, opts...)
    if err != nil {
        log.Fatalf("Dial(%q) = %v", grpcAddr, err)
    }
    MyTestClient := NewMyTestClient(conn)
    MyTestServer := NewHTMLMyTestServer(MyTestClient, stringer)
    net_http.HandleFunc("/MyTest/UnaryCall", MyTestServer.UnaryCall)
    net_http.HandleFunc("/MyTest/Downstream", MyTestServer.Downstream)
    net_http.HandleFunc("/MyTest/Upstream", MyTestServer.Upstream)
    net_http.HandleFunc("/MyTest/Bidi", MyTestServer.Bidi)
    if err := net_http.ListenAndServe(httpAddr, nil); err != nil {
        log.Fatal(err)
    }
}

Also you could write a bit more manual code at rather access NewHTMLMyTestServer and inject the stringer for each client.

func NewHTMLMyTestServer(client MyTestClient, stringer func(req, resp interface{}) ([]byte, error)) *htmlMyTest {
    return &htmlMyTest{client, stringer}
}

This stringer is stored in the struct meaning that every client can have its own stringer.

Maybe this solves your problem?

Reopen if it does not solve your problem.
