I'm back now and I'll have a look to issues and PRs ✅
Github release notes and changelog generator
gren is a small helpful robot that will do for you just create a release from a tag and compile the release notes using issues or commits.
It also can generate a CHANGELOG.md file based on the release notes (or generate a brand new).
Everyone loves neat, transparent, informative release notes. Everyone would also rather avoid maintaining them. What a hassle to have to evaluate what issues have been solved between two points in project's timeline, what types of problems they were, are they important to inform the users about, what issues solved them etc.
Wouldn't it be great to get fantastic release notes compiled for you automaticaly based on all the hard work you put into your GitHub issues and pull requests.
The main motivation for bringing gren to life was the need for auto generating release notes for every tag in a project.
The process, as explained here, requires to go to your project's releases page in GitHub, draft that tag as a new release and manually add what I remembered has changed.
Let gren take care of that for you. It automates this process and also writes release notes for you, creating something like this:
(yes, this is one of 🤖 's actual releases)
Where is the data coming from? There are two options:
If you manage your project with issues, that's where all the information about a change are.
Issue labels increase the level of depth of what the release notes should show, helping gren to group the notes.
e.g. if you see the example above, the issues are grouped by the two labels enhancement and bug, then customised via a config file.
gren generates those notes by collecting all the issues closed between a tag (defaults to latest) and the tag before it (or a tag that you specify).
If you want to be more accurate on the issues that belong to a release, you can group them in milestones and use only the issues that belong to that Milestone.
The output above is a result of release notes built from issues.
In order to have spliendid generated release notes, we reccomend to follow these convensions:
- Start the title with a verb (e.g. Change header styles)
- Use the imperative mood in the title (e.g. Fix, not Fixed or Fixes header styles)
- Use labels wisely and assign one label per issue.
grenhas the option to ignore issues that have one of the specified labels.
The simplest way of getting data is from the commits you write. Even though it doesn't require a machine-readable commit, still would be better to have them in a nice format.
The output would then use commit messages (title + description) to look something like:
- Filter milestones (#75)
- Create milestones data-source option
- Add documentation for the milestones option
- Support GitHub enterprise (#73)
- Support GitHub enterprise
- Add api-url to options documentation
- Update CHANGELOG.md
In order to have spliendid generated release notes, we reccomend to follow these convensions:
- Start the subject line with a verb (e.g. Change header styles)
- Use the imperative mood in the subject line (e.g. Fix, not Fixed or Fixes header styles)
- Limit the subject line to about 50 characters
- Do not end the subject line with a period
- Separate subject from body with a blank line
- Wrap the body at 72 characters
- Use the body to explain what and why not how
Install github-release-notes via npm:
npm install github-release-notes -gFirst, generate a GitHub token, with repo scope, at this link.
Then add this line to ~/.bash_profile (or ~/.zshrc):
export GREN_GITHUB_TOKEN=your_token_hereShow the internet that you use gren for automating your release notes ->
[](https://github-tools.github.io/github-release-notes/)
gren gets the repo information directly from the folder where git is initialised.
# Navigate to your project directory
cd ~/Path/to/repo
# Run the task (see below)
gren releaseOtherwise, you can run it anywhere passing the repo information:
gren release --username=[username] --repo=[repo name]If you don't want to save the token, you can specify one as an option:
gren release --token=[your token]There are two main commands that can be ran with 🤖:
gren will look for the latest tag, draft a new release using the issues closed between when that tag and the one before were created and publish that release in your release panel in your GitHub repo. (@see how to feed 🤖).
Create a CHANGELOG.md file using all the release notes of the repo (like the ones generated by 🤖 ).
If the file exists already, use the --override option to proceed.
gren changelog --overrideTo generate a brand new release notes, using the same approach as per the releases, you have to run the command with the --generate option.
gren changelog --generategren is using Commander.js which generates the --help section.
To trigger the help of a command, run:
# General usage
gren --help
# Command usage
gren help release # or gren release --helpIt's also possible to see all the examples here or directly in the terminal:
gren examples releaseYou can create a configuration file where the task will be ran, where to specify your options. See how to set up the config file The accepted file extensions are the following:
.grenrc.grenrc.json.grenrc.yml.grenrc.yaml.grenrc.js
If you need help to create the configuration file, you can run the following command and follow the instructions
gren init
