Setup Elixir

Setup OpenCov with Elixir

1. Follow the instructions to setup ExCoveralls.

2. Add the following line to your config file.

   config :excoveralls, :endpoint, "http://example.com/opencov"

   Do not forget to replace http://example.com/opencov with your OpenCov endpoint.

3. Put the following in a shell script. I will call it cover.sh here. Check the comments in the shell script.

   #!/bin/sh
   
   # this should be kept secret
   # if your CI is able to setup env vars, this one should be better there
   export COVERALLS_REPO_TOKEN="your_opencov_repo_token"
   
   # when using Travis CI
   export GIT_COMMIT="$TRAVIS_COMMIT"
   export GIT_BRANCH="$TRAVIS_BRANCH"
   
   # use the env variables provided by your CI when possible
   # if non is available, or you want to run it locally, use
   # export GIT_COMMIT="$(git rev-parse HEAD)"
   # export GIT_BRANCH="$(git name-rev --name-only HEAD)"
   
   MIX_ENV=test mix coveralls.post \
     --sha="$GIT_COMMIT" \
     --committer="$(git log -1 $GIT_COMMIT --pretty=format:'%cN')" \
     --message="$(git log -1 $GIT_COMMIT --pretty=format:'%s')" \
     --branch="$GIT_BRANCH"

4. Replace your CI test task with cover.sh instead of mix test.
