Jechová

Checks whether the next meetup is announced on pyvo.cz. If not, sends a message to the specified Slack channel to remind about the situation and provide a link to documentation on how anyone can fix it.

Usage

1. Create a Slack app.
2. Add scopes allowing the app to write to Slack channels (chat:write, chat:write.public).
3. Create a bot user for the app so it can act independently.
4. Install the app for your workspace.
5. Find the bot token (starts with xoxb-) and set it as an environment variable before running the script:

$ export SLACK_API_TOKEN=...
$ python jechova.py '#pyvo-praha' praha-pyvo

First argument is a channel name where the message should go. Beware, if you specify it as #pyvo-praha, standard shell interprets the # as a start of a comment and will ignore the rest of the line. You must pass it either as pyvo-praha or as '#pyvo-praha' (both works).

Second argument is the meetup slug used in the meetup URL. For example, if the meetup URL is https://pyvo.cz/praha-pyvo/, the slug would be praha-pyvo.

When debugging, force sending of the message by adding -f. (And use #automatizace or other less populated channel.)

Deployment

The script is deployed as a daily GitHub Action. SLACK_API_TOKEN needs to be set as a secret. If you want Jechová to handle meetup in your town as well, just add a new workflow.

Dependencies and CI

@dependabot is set up to automatically upgrade dependencies on the repo. It won't automerge PRs if there are no checks though, so there's also a default build as a GitHub Action, currently only consisting of a linter check.

There are no tests. If the code breaks, we'll know when it crashes during the daily cron build.
