Hi,
We would like to be able to generate string to enum value method using
stringer in addition to String() method.
https://github.com/golang/tools/blob/master/cmd/stringer/stringer.go
Is this something that can be added to Stringer? If yes, what is the
process for that?
Thanks.

But you don't need a keyword to get weak pointers. Given the
existence of co
I expect you’re just left with the option of magic comments then, since there’s
not going to be much enthusiasm for adding a new do-nothing keyword to the

Maybe you could use “notwithstanding". It’s an ignored token in the default Go
compiler, and a weak pointer is one that allows an object to be freed
notwithstanding any weak references to it…
It’s not in the spec, though, so it might cause problems with other Go
implementations such as gccgo. I

I have been looking at go's implementation YCbCr to RGB conversion and
there are a few details that are not clear to me.
The implementation follows the JFIF spec
// The JFIF specification says:

// G = Y' - 0.34414*(Cb-128) - 0.71414*(Cr-128)

You can create a slice of the keys in any order you want and use that
to control the iteration. Map iteration is always randomized.

What is your use case?
The advantage of a GC over something like ARC is that you avoid having to
worry about cycles in the heap. Recent GC work has reduced the traditional
weakness of Tracing GCs--pauses--into a minimum (reports is 10
microseconds), so the need might not be there.
There is a pape

The feature I want most in go is automatic reference counting. I don't
really care how mainline GC works but I want the language to be open to the
possibility of ARC-GC. In order for that to be able to handle cycles you
need a weak_ptr type that can requires explicit graduation to a shared_ptr.
Hello Gophers!
There's a fair amount of documentation available[0] about how "go install"
works, particularly in contrast to "go build,"[1,2] but not a lot about
which one is more idiomatic/preferred. Using the standard toolchain, it
seems there's three ways to build your applications:

Cheers,

It's documented. From lang spec
https://golang.org/ref/spec#Function_declarations
"A function declaration may omit the body. Such a declaration
provides the signature for a function implemented outside Go,
such as an assembly routine."
On Thu, 9 Feb 2017 04:15:00 -0800
(PS
Hi! In $GOROOT/src/sync/mutex.go:19 there is a function declaration like
this:
func throw(string) // provided by runtime
The function body is missing. I was wondering what is meant by "provided by
runtime" and how it is done.
I am guessing this is the same as the throw func defined in
