Of course you are right, as usual. I just felt like that was a lot of
hoop-jumping. People already chide me for my affinity for baroque
Makefiles...

If you want to see why people give me a hard time:

And that's AFTER a massive simplification.

I was running tests against a new project, and it was really slow.
When I ran with -x I saw a bunch of build steps that didn't seem to be
necessary. Spelunking through docs, reveals that `go test` doesn't
install artifacts. `go test -i` does install artifacts but doesn't
run the tests.
So I chan
What's weird to me is that go test -i doesn't actually run tests. Maybe go
test -I which does both?

I was playing with a method that wants to print the file:line of the

It is, in fact, a method on an embedded type. That means I can document it

I'm not convinced that the docs quite cover the case I am looking, so
I am posting here.

Hi all,
I can't seem to find this documented, and I'm me involved in some
conversations about using plugins:
What guarantees or limitations surround plugins? Can I compile a host
program with go-1.8.0 and have a third-party plugin compiled with 1.8.1,
and load it?
Can I call methods on plugin-s
Thanks, Ian. Very informative if somewhat disappointing. It more or less
rules out what we wanted to do.

I just can't figure out how to do this. Maybe it can't be done in `go
list` ? Or maybe we're just missing some detail of go modules..
I have a repo (kubernetes, but minimized at
https://github.com/thockin/go-list-modules) which has a "main" go
module, and several other modules in the same repo.
Hi Paul!

Hi. This isn't exactly burning urgent, but it is a long-term issue
for Kubernetes. If there's anything I can do to catalyze the
discussion - tests to run, info to dig up, etc - please let me know.

anged (mtime is a good enough proxy) and I don't
know a priori which packages need codegen. I want to scan the file
tree, find the files that need codegen, check their deps, and only
then run the codegen.

In one of my side-projects, I build a container image. It turns out
to be useful to people, but I got a request to put the license files
for all code used in the binary into the container. Lawyers, what can
you do?
So these people sent me a PR to gather the
nction, and I might even argue for
explicitness. E.g. if I said `go get -mod=vendor` I feel like I am
unambiguously asking the tool to fetch the code and put it in ./vendor and
update the module files. If I said just `go get` I (not so unambiguously)
mean "global" (for me). I find th

Is there any ready-built function that can tell me whether
`strconv.Quote()` would produce a different string than its input, without
actually running it? Or is there a clearly documented set of rules one
could use to test each rune in a string?

Thanks for confirming. I wrote that function and erased a good bit of the
overhead.
bytes.Buffer for the no-escapes path and strconv.Quote otherwise.

We have some packages we would like to break out into their own repos,
but which we don't really want anyone outside of our project to depend
on.
We could, of course, just document that. But I had this thought that

Sure, it's documented, but one mistake and all subsequent invocations
fail. It works, but it's just fragile.

Hi all, I have been banging my head on this all day. I am doinking around
in some code-generation and find myself deep into the go/types package.
Given code like:
```
type E1 string
type E2 E1
```
I loaded the package with x/tools/go/packages. I got the root scope via
`pkg.Types.Scope()`.
How do you make the jump from a go/type.TypeName to ast Decl? Is there
some easy crosslink?
