This VS Code extension converts Markdown to the HTML/Markdown accepted by AnkiWeb. It's intended for use by Anki add-on developers to make it easier to prepare an AnkiWeb description from an existing GitHub README.md.
The extension provides the "Convert to AnkiWeb HTML" command that converts selected Markdown (or the whole file if there is no selection) to HTML and writes the result to the clipboard. If run in a Git repository, it'll try to use the remote URL and current branch to rewrite relative links so that they work without changes if pasted to AnkiWeb.
NOTE: As of August 2023, AnkiWeb supports a basic set of Markdown features. Special handling for newlines was removed as a result (yay!). This extension is still useful to convert relative links and to handle missing features (Heading syntax is not recognized for example).
See CHANGELOG.md for a list of changes.
