How to test config.yml before pushing?

I am working now on creating my own GitHub Learning Labs. I find it difficult to track mistakes that I make inside of the config.yml file. Is there a way to validate the changes before pushing?

@askalski85 this is a great question! We are working on some cool new things to make this easier for you – stay tuned for more info. In the meantime, when you first publish the course, Learning Lab automatically creates it as a draft. This allows you to run through the course and make sure everything is working as expected. We also recommend dropping your code in http://www.yamllint.com/ to make sure there aren’t any unexpected YAML formatting errors!

I’d love to see yamllint automatically run on every yaml/yml file in pull requests. It’d catch so many mistakes and seems like it’s always applicable.

This is really helpful, i spent hours stuck not knowing why my jekyll build was failing only to parse my _config.yml through yamlint and found it had a syntax error. By the way, the yaml extension on vscode is a saver too.

For anyone who is interested - we’ve also released a new course building tool that will validate the course yaml for you! You can access it here: https://lab.github.com/new
