Import snippets

<<< puts a file, or one part of it, into a code block. It takes the same title, ranges and options as a fence.

<<< ./snippets/example.ts
<<< ./snippets/example.ts#greet
<<< ./snippets/example.ts#greet ts {1|2}
<<< @/snippets/example.ts {*}{lines:true}

The path is relative to the markdown file. @/ is the folder of the entry slides.md.

#greet is a region written in the file between markers:

// #region greet
export const greet = (name: string) => `Hello ${name}`;
// #endregion greet

Also recognised are <!-- #region -->, /* #region */ and # region. The markers are not part of the imported code. A missing file is a warning and a comment in the block.

To edit the imported file from the slide while the dev server runs, see Writing back to files.
