Add Tab's railroad.js to the blog - Include railroad.js from http://tabatkins.github.io/railroad-diagrams/ - Include railroad.css from the same, and tweak it to match my style a bit better - Add a railroad-utils.js file that declares a railroadDiagram function. It takes a builder function and an element ID, calls the builder and adds the resulting diagram to the element with the given ID. - Add a railroad_diagram shortcode that wraps that all up so you can write a diagram inline with a post. - Add script includes if the railroad_diagram shortcode is used. The shortcut sets a variable in the page's .Scratch that is looked up in the head partial template to determine whether to include these scripts. 2022-08-16 09:06:30 -07:00			`{{ $id := .Get "id" }}`
