Geany doesn't support Go out of the box, but you can configure it to have excellent support. In the preferences, you can tell it the "go build" commands, and it will be able to build & run your project in Geany's integrated terminal and attach gdb for debugging. Also in the preferences you can tell it the format of go error messages, which allows it to highlight lines with compile errors.
