I am certainly a GO newbie so I will apologize in advance. I am playing around with a GO app that imports martini for example. Every time I run the app, I have to run "go get github.com/codegangsta/martini". Any way to NOT have to do this? Either way, how would this work in an offline environment? I am considering GO for an app that will be offline with no internet access.
From the go documentation:
Get downloads and installs the packages named by the import paths, along with their dependencies.
To expand on that: go get will clone the code you're requesting from the repository (in this case github.com/codegangsta/martini) as well as any code that that code imports and store it in your local $GOPATH/src/ directory then build it and store it so that is available to call via import, so you should never have to call go get more than once unless your GOPATH is being changed and it should always be available locally after the initial go get.
