Code Block

[jbmoelker]

Astro provides a built-in Code component that we could easily use to introduce a Code Block component.

Questions

• Can and should we use these both for multiline and inline code? For inline code we could extemd how code is rendered in Textblock/Text.astro.
• Can and should we give a similar code syntax highlight experience in DatoCMS?

Since DatoCMS already has good support for code inside of Structured Text (including languages and syntax highlighting), we can use that, and then we don't need to introduce a new Block component.

Since the Code component is built-in to Astro, we could use it directly in our implementation of Structured Text for Astro:

---
import type { Code as CodeNode } from 'datocms-structured-text-utils';
import { Code } from 'astro:components';

interface Props {
  node: CodeNode;
}

const { node } = Astro.props;
const { code, language } = node;
---

<Code code={ code } lang={ language } />

The only reason to still introduce a new Code Block in DatoCMS would be to configure wrap, theme and maybe transformers. This can again also be done by setting a custom renderer for code blocks in Textblock/Text.astro, so maybe the simple enhancement suggested before is sufficient.

Also add support for the highlight property that DatoCMS exposes?

highlight Optional Array<number>
A zero-based array of line numbers to highlight (ie. [0, 1, 3])

Can be mapped with to Shiki's transformerNotationHighlight (Shiki being the implementation behind Astro's Code component).
