Software development thoughts around Ubuntu, Python, Golang and other tools

Getting going with Go (golang)

leave a comment »

For quite a while I’ve been wanting to get stuck into learning the Go programming language, after a colleague at Canonical (Gustavo Niemeyer) wrote enthusiastically about it… and today I took a bit of time to get started.

Getting setup on my Ubuntu Maverick VM was pretty straight forward:

  • Add Gustavo’s software channel:
sudo add-apt-repository ppa:niemeyer/ppa
sudo apt-get update
sudo apt-get install golang
export GOROOT=/usr/lib/go
  • This also adds ‘gorun‘, which effectively saves you having to compile and link each time you edit your go source file – nice
  • I had to then grab the go source to get the vim syntax highlighting etc. (files are provided for most editors in the source).
Whenever learning a new language I always find it incredibly helpful to be able to see all the options available – code auto-completion. So finally, I installed gocode, but had to make the following changes to get it to `make install`:
  • Installed golang-weekly (rather than golang) to get a more recent version…
  • Reverted the latest commit to gocode which was an update for the latest golang weekly release, which hadn’t yet hit the PPA.
With those changes, gocode installed and worked beautifully – learning with auto-completion is like seeing with peripheral vision for the first time.
Next week I hope to checkout the gocheck testing library as well as the Effective Go tutorial. As much as I love Python, it’s great getting stuck into a new language!
