How to use Air with go run . and skip the build step in Air.

[ADTC]

If you use go run ., Go will build and run in a single step. The build is stored in a random temporary folder in /var. Theoretically it's the same as using go build -o ./tmp/main . then running ./tmp/main.

But if you're interested in using go run . by itself, here's how to do it:

bin = ""
cmd = "echo 'Skipping build step in Air...'"
full_bin = "go run ."

The trick is to use full_bin instead of bin because the former is a proper shell command, while the latter is just a file reference.

Note: Unfortunately this still creates an empty tmp directory.
