VS Code Support

similar to #465

I'm just getting started with go and am having trouble integrating with VS Code.

I'm on mac and have installed tinygo via homebrew.

According to docs I can run

export GOPATH=$GOPATH:/usr/local/Cellar/tinygo/0.13.1/libexec/tinygo

This however does nothing for vscode import errors.

cannot find package "machine" in any of:
	/usr/local/Cellar/go/1.14.2_1/libexec/src/machine (from $GOROOT)
	~/go/src/machine

I'm assuming I need to symlink /usr/local/Cellar/tinygo/0.13.1/libexec/tinygo into ~/go/src/machine

Does anyone know how to fix these errors in vscode? What is the recommended approach? As I said i'm inexperienced with golang,

It appears that the GOPATH wasn't picked up VS Code. Remeber that export only works in the current shell, it is not system-wide. You might need to change some settings in VS Code itself to get this to work.

@aykevl Thanks for quick reply

I have added tinygo to my .bash_profile

export GOPATH=$GOPATH:/usr/local/Cellar/tinygo/0.13.1/libexec/tinygo

go env GOPATH
returns
/usr/local/Cellar/tinygo/0.13.1/libexec/tinygo

after closing and restarting vscode Go: Current GOPATH now returns the above path.

This works but is it the recommended way of writing code in go?

Is there a way to get type hints for my specific board? its the Arduino nano 33 IoT

looking at sample code

package main

import (
	"machine"
	"time"
)

func main() {
	led := machine.LED
	led.Configure(machine.PinConfig{Mode: machine.PinOutput})
	for {
		led.Low()
		time.Sleep(time.Millisecond * 500)

		led.High()
		time.Sleep(time.Millisecond * 500)
	}
}

I get type hints for machine.PinConfig but not for machine.LED

You will also need to configure build tags. I think you can use go.buildTags for that. To get the list of build tags, run:

tinygo info arduino-nano33

I know this is a bit involved. I'm hoping that we can properly fix this in the future (#941 is a part of that). Until then, this should work.

Great thanks for all your help. I'm excited to write some Go!
