Go Commons

Find yourself needing the same packages over and over?

Me too.

Instead of re-writting them for each project/client/company I decided it was time to do it one more time in public.

Getting Started

To use these packages simply:

go get github.com/corsc/go-commons/

(vendoring recommended)

Contributions

Contributions, suggestions, bug request, etc are all welcome. Please use Github Issues and Pull Requests.

Running the tests

Nothing special, standard go test ./... will get the job done.

If me, you want the fastest possible tests, I would skip vendor by using:

go test $(go list ./... | grep -v /vendor)

Lint checking contributions

Please check all PRs before sending them using the following settings

gometalinter --config=gometa-config.json ./...
