Setting up a Go development environment
Go has a pretty neat development environment, and its helpful to set up a standard GOPATH on your workstation up front. This is what I do:
- mkdir ~/go
- add the following to .bashrc (or some file that configures your env on login)
- export GOPATH=~/go
- export PATH=$GOPATH/bin:$PATH
Now, after you log in, you can do things like:
