use -1 as the key to debug. once that works, use zero as the key.

Yes I did. Can I say a method set is the one which associates an interface
with methods?

I have the same problem with latest version (1.11.4).
I've been trying to use two shared objects A and B (with c-shared build
mode), and use my C++ program to pass the functions exported by A to B
through GoInterface parameters. However, in B the type assertion from
GoInterface failed...

It can be verified by use of tuples
x, (y, z) := A[id1], B[id2]
But the above doesn't work. Why ?

I am using the below code to encrypt and decrypt the data. Now I want to
encrypt the data from Node JS and want to decrypt the data from Go lang.
But I am not able to achieve it using GO lang.

encode: function(key, data) {
return new Buffer(xorStrings(key,

Almost. The method set *of an interface* is the set of methods in the
interface. But other types, aside from interfaces, also have

It looks like "go build ./cmd/..." works when there's only one directory
under cmd. When there are multiple directories there, the command doesn't
generate any binaries for me.
I would just do
$ go build ./cmd/foo
$ go build ./cmd/bar
They create binaries in the current directory so you don't

wouldn't the compiler be able to use the fact that a return value is known
not to be being used in a particular call, somewhere one or more of the
returned values are assigned to a blank, to be able to generate faster code
for that call?
or is it already being done? because, it seems to me,

v is nil. It is declared but never assigned a value. You are
dereferencing v to call m, causing nil ptr dereference.

It works on all sub directories. But `go build` puts the binary
type a interface{
m()
}
type abc int
func (abc) m() {}
func main() {
var v a
v.m()
}

I know "nil" is zero values for slices, maps, interfaces, etc but I don't
know what "nil" implays. Does nil implay the absence of value or a variable
has't been initialized yet or something else?

Basically yes, all of the above. This pattern
Hi
I guess the problem is the range over the input.
if you have utf8 runes > 1byte in your input,
you are not iterating with over each byte anymore.
the i is the index of a encoded rune the string., right?

I was working on a tool that needed to know the file system paths and
version information of some of its dependencies from go.mod for code
generation. I couldn't find any official way of obtaining these
(debug/gosym was close, but didn't work for the current binary on any
OS), so I wrote this

I checked the type of the variable "v" with interface{} using TypeOf
function in reflect package but it returned "nil".
var v interface{}
fmt.Println(reflect.TypeOf(v))
Process finished with exit code 0

That is what the reflect.TypeOf function is supposed to do. The docs
