x/playground: add vet #7597

josharian · 2014-03-20T16:41:56Z

On potential pain of button overload, it might be useful to add a Vet button to the
playground. It would run go vet over the program and display the output. This would
increase vet visibility and help make self-service debugging easier. (E.g. It would have
helped with https://groups.google.com/forum/m/#!topic/golang-nuts/IneZcyGGJYM )

Comment 3:

Is this something that I can work on? If so, do you mind pointing me in the right
direction? (Where is the relevant codebase? Anything I need to be aware of for
testing/portability to the hosted playground environment?)

Comment 4:

Please go ahead.
http://code.google.com/p/go-playground is where the code lives. Take a look at how the
fmt handler works. It would be similar to that.

Comment 5:

Thanks. The front-end part was surprisingly pleasant and straightforward.
Sadly, the rest is going to be disruptive. It will require converting vet into a
package. I have a couple of vet modules queued for 1.4. Once those land (or crash), I'll
email golang-dev to see how folks feel about turning vet into a package.

Comment 6:

I like this as it would hopefully reduce some of the traffic to golang-nuts.
It would also be nice if there was a race option for the run button, like the imports
option on the Format button. It would hopefully have a similar effect to bring more
visibility to the race-detector.
That may not be possible though, since the race detector probably won't work on the
playground platform. AFAIK it only works on 64-bit darwin/linux/windows/freebsd, while
the playground is nacl/386 I believe.

minux · 2014-07-09T15:20:27Z

Comment 7:

FYI, the playground is nacl/amd64p32.
Due to the way the race detector works and nacl works, it's impossible
to support the race detector on nacl.

The front-end work I did for this (now perhaps a bit dated) can be found at https://codereview.appspot.com/103750044/ and https://codereview.appspot.com/104770043/. The hard part--splitting vet into a package and a command--is still outstanding.

adg · 2015-01-11T23:11:39Z

Now that the new sandbox server is running on a VM, we can think about just
calling the vet command directly.

Running playground on a sandbox makes easier to execute cmd/vet on a piece of code.

These two CLs addresses this issue, by updating both sandbox, playground frontend application and a static file shared with godoc.

Currently, it is implemented following this way:
1 - Added one entry point (/vet) to sandbox, which calls cmd/vet and parses the result as if it were a compilation process.
2 - Updated playground.js, so it calls /vet at backend.
3 - Updated Dockerfile with go get to install cmd/vet

I considered the alternative of overloading /compile endpoint with a parameter, thus switching back and forth between compilation and vetting. The reason I did not do it was that it seemed a cleaner design to keep separated different resources with different goals.

Of course, I am ready to change the implementation after debate.

Anyway, I should like to open as soon as possible another CL updating docs to mention the existence of a proxy at golang.org/compile - so other contributos do not get lost on why query-string calls are made where the sandbox expects for JSON.

Change https://golang.org/cl/100776 mentions this issue: playground: add vet

Playground needs godoc to support calls to /vet endpoint in playground.js. Optional parameter "vetEl" is added to the function "playground". If it's passed then the js installs the click handler to the element. There is a corresponding CL 100776 for the playground code.

Change https://golang.org/cl/107455 mentions this issue: godoc: display "go vet" errors before the output of a program

This change adds an option to run "go vet" for the playground program and display errors before any output. To enable this, the playground function has to be supplied with opts.enableVet set to true. Vet check is performed only for succesfully run programs, meaning that the "/compile" endpoint returned no errors. This change highlights lines printed to stderr as errors (in red). There is a corresponding change for the Playground: CL 100776.
