### .env.gitlab
Environment variables read from `~/.env.gitlab` and current `.env.gitlab`

`~/.env.gitlab` 

```
GITLAB_API_ENDPOINT=http://example.com/api/v4
GITLAB_API_PRIVATE_TOKEN=XXXXXXXXXXXXXXXXXXX
TEMPLATE_FILE=gitlab_mr_release.md.erb
DEFAULT_TITLE=Release <%= Time.now %> <%= source_branch %> -> <%= target_branch %>
```

current `.env.gitlab`

```
GITLAB_PROJECT_NAME=group/name
TEMPLATE_FILE=gitlab_mr_release.md.erb
DEFAULT_SOURCE_BRANCH=develop
DEFAULT_TARGET_BRANCH=master
DEFAULT_LABELS=release
```

If defined both `~/.env.gitlab` and current `.env.gitlab`, current `.env.gitlab` is priority

### variables in template
```markdown
# MergeRequests
<% merge_requests.each do |mr| -%>
* [ ] !<%= mr.iid %> <%= mr.title %> @<%= mr.author.username %>
<% end -%>
```

`merge_requests` is array of [MergeRequest](https://github.com/gitlabhq/gitlabhq/blob/master/doc/api/merge_requests.md#get-single-mr)

### variables in DEFAULT_TITLE

DEFAULT_TITLE=Release <%= Time.now %> <%= source_branch %> -> <%= target_branch %>
```

`DEFAULT_TITLE` supports erb.
