When sending Read() via an RPC call or traversing locks, it is
significantly faster to return EOF in the same call as returning the rest
of the available data, than to call Read a second time to get the EOF.
It's not that hard to handle the EOF semantics. Yes, you have to know what
io.EOF means.

Hi Jeffery,
You can build large projects with many repos using Go modules.
Firstly, you can reference the other repos and use the latest "master"
version by writing "master" where the v verson is in the file,
then use "go mod tidy"
Second, you can use "go work" to create a workspace with
I agree with what Brian said and would like to suggest the following two

Hi all,
I was very confused by the behavior I was seeing while testing a simple
program with http.StripPrefix:
package main
import (
"fmt"
"net/http"
)
func main() {
mux := http.NewServeMux()
mux.HandleFunc("/other/", func(w http.ResponseWriter, r *http.Request) {
fmt.Println(r.URL.Path)

Autocomplete and a go language server (gopls) add a ton of speed because
you don't need to look up the docs for function and variable names. And go
to definition improves speed navigating code significantly.
But vim-go can do both, so why not just use it?
It's a significant speed increase to
you can achieve this using an io.Pipe. The io.Pipe function returns a
connected pair of *PipeReader and *PipeWriter, where writes to the
*PipeWriter are directly read from the *PipeReader. The Write call on the
*PipeWriter will block until the data is read from the *PipeReader.

No... The previous example streams the file as the post request. The only
difference in your example is that you're using stdin.
It's not that complicated, files also implement io.reader.

Comparing with empty is something I've needed to do a bunch of times
and have been unable to do.

The thing I ran into with this today was, if you want to compare two interfaces:
var foo1 Thing
var foo2 Thing
Ordinarily you can do foo1 == foo2 and it does pointer-wise comparison.
But in a generic function, as an example:
// IsEmpty checks if the interface is equal to nil.
func IsEmpty[T

I definitely fork things and use "replace" quite frequently.
When forking something you have to tell Go where to find it, that's
what "replace" is for.
There's a issue about using replaces in `go install` without a go.mod:

Hi all,
I've built a streaming RPC library compatible with grpc Protobuf service
definitions that can do bidirectional streaming to the web browser over any
AsyncIterable channel, currently using WebSockets but can also use Message
channel to webassembly and other messaging approaches.

Doesn't it make more sense to fix the cyclic dependencies rather than hack
the go compiler and make it do something it wasn't designed to do?

Hi all,
There have been several discussions about shellquote in go-nuts in the past:

I've found it necessary to use both Split and Join in some cases when
working with exec.Command.

I'm trying to use packages.Load to parse the following comment:

I'm trying to parse the my:value comment similar to go:embed.

Frank,
Am I missing something - can't you just put multiple go files in the same
directory?
All the go files in the directory will be combined into the same package.
This is frequently used for other codegen, like Protobuf.
