It's great to release software. And even better when people actually know about it!
One way to let people know about your new software releases is to tell them on Twitter. But we're software developers, not social media managers -- so that means we automate all the things.
With tweetrel, you can have GitHub send a tweet for you whenever you make a release.
pip install tweetrel
First, you need to add your Twitter API details as GitHub secrets. You'll need to sign up for a Twitter API account if you don't already have one. Once you've signed up, Twitter will give you four keys: consumer_key, consumer_secret, access_token, and access_token_secret. Create a new secret called TWITTER, and paste those four keys in, with a space between each one.
If you need to send Tweets on behalf of a different user to the one attached to your login, you'll need to authenticate with Twitter as that user. Run tweetrel-auth in your terminal and follow the instructions, and it will give you the access_token and access_token_secret you need -- paste them (after a space) after your consumer_key and consumer_secret and that will let you send tweets as the user you authenticated as.
Next, in your terminal, cd to the root of your repo, and then run:
tweetrel-install
That will set tweetrel up for you to run automatically upon release. You'll see two folders added to your .github folder, containing the YAML workflow and python script. No additional setup is needed, other than pushing these to GitHub:
git add -A .github
git commit -am 'Add tweetrel`
git push
You can test this without actually making a release by going to your GitHub repo in your browser, clicking the Actions tab, then clicking on the tweet action, and clicking the run workflow button. That will use GitHub's example release payload for testing.
Once you've confirmed it's working, try making a release on GitHub, and check that you see the green tick in the Actions tab showing a successful run of the tweet action.
As you'll see, the default template is:
New #{repo} release: v{tag_name}. {html_url}\n\n{body}
You can customize that by setting the TWEETREL_TEMPLATE environment variable. For instance, add this (with suitable indentation) to the env: section of your workflow YAML file:
TWEETREL_TEMPLATE: |
We are proud to announce the {tag_name} release of {repo}.
For more, see: {html_url}. Here are the details:
{body}
The | is the YAML character that indicates a multiline string. The sections in {...} are the Python formatting template variables that will be replaced by the details of your release. You don't need to include all of them if you don't want them.
