convertRichTextToMarkdown

function convertRichTextToMarkdown(runs: RichTextRun[], theme: Theme = {}): string;

The inverse of convertMarkdownToRichText: bold, italic and strikethrough become their markers again, a run carrying a link becomes [text](url), and a run set in the theme's code font becomes a code span.

A code run carries no flag of its own — it is recognised by its font — so pass the same theme both ways and the pair round-trips. Runs are written one after another in the order given, without merging neighbours that share a style, so deeply nested formatting may come back expressed differently while reading the same.

Parameters

Parameter	Type	Description
`runs`	`RichTextRun[]`	The runs to convert. An empty array gives an empty string.
`theme` (optional) `= {}`	`Theme`	The theme the runs were styled with. Only the code font is read from it.

Returns

string — the Markdown representing the runs.

Throws

Exception	Condition
`IllegalArgumentException`	no argument is passed, the value is not an array, or an element is not a run with text.

Examples

Back to Markdown

const runs = convertMarkdownToRichText("**bold** and `code`");

convertRichTextToMarkdown(runs); // => "**bold** and `code`"

A link keeps its text styled

convertRichTextToMarkdown([
  { text: "site", style: { bold: true, link: { url: "https://example.com" } } }
]); // => "[**site**](https://example.com)"
