This PR improves support for rendering markdown documents. ## After the updates https://github.com/zed-industries/zed/assets/18583882/48315901-563d-44c6-8265-8390e8eed942 ## Before the updates https://github.com/zed-industries/zed/assets/18583882/6d7ddb55-41f7-492e-af12-6ab54559f612 ## New features - @SomeoneToIgnore's [scrolling feature request](https://github.com/zed-industries/zed/pull/6958#pullrequestreview-1850458632). - Checkboxes (`- [ ]` and `- [x]`) - Inline code blocks. - Ordered and unordered lists at an arbitrary depth. - Block quotes that render nested content, like code blocks. - Lists that render nested content, like code blocks. - Block quotes that support variable heading sizes and the other markdown features added [here](https://github.com/zed-industries/zed/pull/6958). - Users can see and click internal links (`[See the docs](./docs.md)`). ## Notable changes - Removed dependency on `rich_text`. - Added a new method for parsing markdown into renderable structs. This method uses recursive descent so it can easily support more complex markdown documents. - Parsing does not happen for every call to `MarkdownPreviewView::render` anymore. ## TODO - [ ] Typing should move the markdown preview cursor. ## Future work under consideration - If a title exists for a link, show it on hover. - Images. - Since this PR brings the most support for markdown, we can consolidate `languages/markdown` and `rich_text` to use this new renderer. Note that the updated inline text rendering method in this PR originated from `langauges/markdown`. - Syntax highlighting in code blocks. - Footnote references. - Inline HTML. - Strikethrough support. - Scrolling improvements: - Handle automatic preview scrolling when multiple cursors are used in the editor. - > great to see that the render now respects editor's scrolls, but can we also support the vice-versa (as syntax tree does it in Zed) — when scrolling the render, it would be good to scroll the editor too - > sometimes it's hard to understand where the "caret" on the render is, so I wonder if we could go even further with its placement and place it inside the text, as a regular caret? Maybe even support the selections? - > switching to another markdown tab does not change the rendered contents and when I call the render command again, the screen gets another split — I would rather prefer to have Zed's syntax tree behavior: there's always a single panel that renders things for whatever tab is active now. At least we should not split if there's already a split, rather adding the new rendered tab there. - > plaintext URLs could get a highlight and the click action ## Release Notes - Improved support for markdown rendering. |
