Development

Before you get started, make sure you have installed the following tools::

$ python3 -m pip install -U cookiecutter>=1.4.0
$ python3 -m pip install pre-commit bump2version invoke ruamel.yaml halo
$ go get -u golang.org/x/tools/cmd/goimports
$ go get -u golang.org/x/lint/golint
$ go get -u github.com/fzipp/gocyclo
$ go get -u github.com/mitchellh/gox  # if you want to test building on different architectures

Remember: To be able to excecute the tools downloaded with go get, make sure to include $GOPATH/bin in your $PATH. If echo $GOPATH does not give you a path make sure to run (export GOPATH="$HOME/go" to set it). In order for your changes to persist, do not forget to add these to your shells .bashrc.

With the tools in place, it is strongly advised to install the git commit hooks to make sure checks are passing in CI:

invoke install-hooks

You can check if all checks pass at any time:

invoke pre-commit

Note for Maintainers: After merging changes, tag your commits with a new version and push to GitHub to create a release:

bump2version (major | minor | patch)
git push --follow-tags

Note

This project is still in the alpha stage and should not be considered production ready.
