GitHub workflows are written in YAML format. In this video, learn more about the usefulness of YAML files.
- [Instructor] GitHub workflows are coded in YAML format. The letters Y-A-M-L make a recursive acronym for "YAML Ain't Markup Language." See what they did there? Indeed, YAML is not a markup language, it's a programming language for data serialization. We'll use YAML to describe and share the attributes used in our workflows and actions, that's the data. And serialization in this case means we're presenting the data in an ordered fashion that's easily understood by humans and machines. YAML files use the .yml and .yaml extensions to identify the format. You can use either one when you're naming YAML files used as GitHub workflows. One thing you'll want to watch closely with YAML files is formatting. YAML uses indentations along with colons, dashes, and other characters to delimit the beginnings of attribute definitions and the lists, maps, and key value pairs they contain. Fortunately, many modern editors will handle YAML indentation for us, or at least point out when we've made an error in formatting. Editors like Vim, Visual Studio Code, Atom, and even GitHub's built-in web editor are great tools to use for coding YAML-based workflows.
