Fully automate changelog generation - This gem generates change log file based ontags,issues and mergedpull requests (and splits them into separate lists according labels) from GitHub Issue Tracker.

Since now you don't have to fill yourCHANGELOG.md manually: just run the script, relax and take a cup of ☕ before your next release! 🎉

What’s the point of a change log?

To make it easier for users and contributors to see precisely what notable changes have been made between each release (or version) of the project.

Because software tools are for people. If you don’t care, why are you contributing to open source? Surely, there must be a kernel (ha!) of care somewhere in that lovely little brain of yours.

Since GitHub allows you to make only 50 requests without authentication it's recommended to run this script with a token (-t, --token option)

You can easilygenerate it here.

And:

• Run with key-t [your-16-digit-token]

• Or set environment variableCHANGELOG_GITHUB_TOKEN and specify there your token.

  i.e. add to your~/.bash_profile or~/.zshrc or any other place to load ENV variables string :

    export CHANGELOG_GITHUB_TOKEN="your-40-digit-github-token"

So, if you got error like this:

! /Library/Ruby/Gems/2.0.0/gems/github_api-0.12.2/lib/github_api/response/raise_error.rb:14:in `on_complete'

It's time to create this token or wait for 1 hour before GitHub reset the counter for your IP.

• Nothing is impossible!

• Open anissue and let's make generator better together!

• Bug reports, feature requests, patches, well-wishes are always welcome ❗

• I already use GitHub Releases. Why do I need this?

GitHub Releases is a very good thing. And it's very good practice to maintain it (not so much people using it yet)! ㊗️

BDW: I would like to support GitHub Releases innext releases ;)

I'm not try to compare quality of auto-generated and manually generated logs.. but:

The auto generated Changelog really helps even if you manually fill Releases notes!

For example:

When I found a closed bug - it's very useful to understand, in which release it was fixed. In that case you can easily find this issue by # inCHANGELOG.md.

• it's not so quite easy to find it in manually filled Releases notes.
• this file can also help you to build your Release note and not miss features in manually-filled list.

In the end:

I think, that GitHub Releases is more for end-users.ButCHANGELOG.md could stay in the repo for developers with detailed list of changes.And it's nothing bad to combine GitHub Releases andCHANGELOG.md file together in that manner.

• I received a warning: GitHub API rate limit exceed, what does this mean?

GitHublimits the number of API requests you can make in an hour. You can make up to 5,000 requests per hour. For unauthenticated requests, the rate limit allows you to make up to 60 requests per hour. Unauthenticated requests are associated with your IP address, and not the user making requests.

If you're seeing this warning:

1. Make sure you're providing an OAuth token so you're not anonymously making requests. This will increase the number of requests from 60 to 5000 per hour.
2. You probably have a large repo with lots of issues/PRs. You can use the--max-issues NUM argument to limit the number of issues that are pulled back. For example:--max-issues 1000

1. Create an issue to discuss about your idea
2. [Fork it] (https://github.com/skywinder/Github-Changelog-Generator/fork)
3. Create your feature branch (git checkout -b my-new-feature)
4. Commit your changes (git commit -am 'Add some feature')
5. Push to the branch (git push origin my-new-feature)
6. Create a new Pull Request
7. Profit! ✅
