We now use the parser and renderer from the `markdown` crate for
Markdown Preview, instead of maintaining two separate code paths.
How it works:
`markdown_preview_view.rs` is now a consumer of `MarkdownElement`. It
acts as a thin wrapper, handling things like resolving URL clicks and
image URLs, which can vary between consumers. It also handles syncing
the editor selection with the active block in the preview. The APIs for
this are provided by `MarkdownElement`.
All the heavy lifting like parsing HTML, rendering block markers on
hover, handling the active block, etc. is done by `MarkdownElement`.
Everything is opt-in. For example, markdown in the Agent Panel can
choose not to enable block marker rendering or HTML parsing, while
Markdown Preview opts into those features.
Final outcome:
For Markdown Preview View:
- Added:
- Selection support in the preview
- Stays:
- Syncing between editor and preview
- Autoscroll
- Hover and active block markers
- Checkbox toggling
- Image rendering
- Mermaid rendering
For the `markdown` crate:
- No changes for existing consumers like the Agent Panel
- Consumers can now opt into:
- HTML rendering
- Block marker rendering
- Click event handling
- Custom image resolvers
- Mermaid rendering

This extracts a `language_core` crate from the existing `language`
crate, and creates a `grammars` data crate. The goal is to separate
tree-sitter grammar infrastructure, language configuration, and LSP
adapter types from the heavier buffer/editor integration layer in
`language`.
## Motivation
The `language` crate pulls in `text`, `theme`, `settings`, `rpc`,
`task`, `fs`, `clock`, `sum_tree`, and `fuzzy` — all of which are needed
for buffer integration (`Buffer`, `SyntaxMap`, `Outline`,
`DiagnosticSet`) but not for grammar parsing or language configuration.
Extracting the core types lets downstream consumers depend on
`language_core` without pulling in the full integration stack.
## Dependency graph after extraction
```
language_core ← gpui, lsp, tree-sitter, util, collections
grammars ← language_core, rust_embed, tree-sitter-{rust,python,...}
language ← language_core, text, theme, settings, rpc, task, fs, ...
languages ← language, grammars
```
## What moved to `language_core`
- `Grammar`, `GrammarId`, and all query config/builder types
- `LanguageConfig`, `LanguageMatcher`, bracket/comment/indent config
types
- `HighlightMap`, `HighlightId` (theme-dependent free functions
`highlight_style` and `highlight_name` stay in `language`)
- `LanguageName`, `LanguageId`
- `LanguageQueries`, `QUERY_FILENAME_PREFIXES`
- `CodeLabel`, `CodeLabelBuilder`, `Symbol`
- `Diagnostic`, `DiagnosticSourceKind`
- `Toolchain`, `ToolchainScope`, `ToolchainList`, `ToolchainMetadata`
- `ManifestName`
- `SoftWrap`
- LSP data types: `BinaryStatus`, `ServerHealth`,
`LanguageServerStatusUpdate`, `PromptResponseContext`, `ToLspPosition`
## What stays in `language`
- `Buffer`, `BufferSnapshot`, `SyntaxMap`, `Outline`, `DiagnosticSet`,
`LanguageScope`
- `LspAdapter`, `CachedLspAdapter`, `LspAdapterDelegate` (reference
`Arc<Language>` and `WorktreeId`)
- `ToolchainLister`, `LanguageToolchainStore` (reference `task` and
`settings` types)
- `ManifestQuery`, `ManifestProvider`, `ManifestDelegate` (reference
`WorktreeId`)
- Parser/query cursor pools, `PLAIN_TEXT`, point conversion functions
## What the `grammars` crate provides
- Embedded `.scm` query files and `config.toml` files for all built-in
languages (via `rust_embed`)
- `load_queries(name)`, `load_config(name)`,
`load_config_for_feature(name, grammars_loaded)`, and `get_file(path)`
functions
- `native_grammars()` for tree-sitter grammar registration (behind
`load-grammars` feature)
## Pre-cleanup (also in this PR)
- Removed unused `Option<&Buffer>` from
`LspAdapter::process_diagnostics`
- Removed unused `&App` from `LspAdapter::retain_old_diagnostic`
- Removed `fs: &dyn Fs` from `ToolchainLister` trait methods
(`PythonToolchainProvider` captures `fs` at construction time instead)
- Moved `Diagnostic`/`DiagnosticSourceKind` out of `buffer.rs` into
their own module
## Backward compatibility
The `language` crate re-exports everything from `language_core`, so
existing `use language::Grammar` (etc.) continues to work unchanged. The
only downstream change required is importing `CodeLabelExt` where
`.fallback_for_completion()` is called on the now-foreign `CodeLabel`
type.

Summary
Add a new grid_cols_max_content GPUI styling API that uses minmax(0,
max-content) for grid column sizing. This allows columns to
automatically size based on their content width while remaining
responsive when the container shrinks.
Applied the fix to both markdown preview (markdown_renderer.rs) and
agent panel (markdown.rs) table rendering. Table borders now wrap
tightly around content instead of stretching to full container width.
Fixes#50044
Approach
A new grid_cols_max_content API is added (as discussed with
@MikaylaMaki):
style.rs — New grid_cols_max_content: Option<u16> field
styled.rs — New .grid_cols_max_content(cols) builder method
taffy.rs — New to_grid_repeat_max_content() using minmax(0, max-content)
markdown_renderer.rs — Swapped .grid_cols() → .grid_cols_max_content(),
moved border to grid div, wrapped in v_flex().items_start() so border
hugs content
markdown.rs — Applied same fix for agent panel tables:
grid_cols_max_content, border on grid div, wrapped in
div().flex().flex_col().items_start() container

Render `[x]` and `[ ]` as checkbox widgets when they appear as the sole
content of a markdown table cell. Previously these were displayed as raw
text. List-item checkboxes were already rendered correctly; this extends
the same treatment to table cells.
Fixes#50045.
## What this does
- Table cells containing only `[x]`, `[X]`, or `[ ]` now render as
visual checkboxes instead of plain text
- Both markdown rendering paths are covered: the `markdown` crate (agent
panel, chat) and the `markdown_preview` crate (file preview)
- Checkboxes are display-only, matching the existing list-item checkbox
behavior
## How it works
pulldown-cmark splits `[x]` in table cells into three separate `Text`
events (`[`, `x`, `]`) rather than emitting a `TaskListMarker` event
(which only fires for list items per the GFM spec). The fix operates at
each crate's natural interception point:
- **`markdown` crate**: After all text events for a table cell have been
buffered, `replace_pending_checkbox()` checks the accumulated text
before the cell div is finalized. If it matches the checkbox pattern,
the pending text is replaced with a `Checkbox` widget.
- **`markdown_preview` crate**: In `render_markdown_text()`, text chunks
whose trimmed content matches the checkbox pattern are rendered as
`MarkdownCheckbox` widgets instead of `InteractiveText`.
## Scope
Three files, purely additive:
- `crates/markdown/src/markdown.rs` — `replace_pending_checkbox()` on
builder, called at `TableCell` end
- `crates/markdown_preview/src/markdown_renderer.rs` — checkbox
detection in `render_markdown_text()`
- `crates/markdown_preview/src/markdown_parser.rs` — test only
No changes to parser data models, GPUI, or any shared infrastructure.
## What's not in scope
- **HTML `<input type="checkbox">`** — pulldown-cmark strips these as
raw HTML. Supporting them requires HTML tag parsing, which is a separate
concern.
- **Interactive (click-to-toggle) checkboxes in tables** — table
checkboxes are display-only. List-item checkboxes in Zed support
Cmd+click toggling, but extending that to table cells would require
tracking source ranges across the split parser events, which is a
separate enhancement.
## Follow-up
Table checkbox interactivity (Cmd+click toggle) is straightforward to
add as a follow-up — the source ranges are already available in
`markdown_preview`, and the `markdown` crate would need minor callback
plumbing.

/>
## Test plan
**Unit tests** (2 new):
- `test_table_with_checkboxes` (markdown_preview) — parser delivers
`[x]`/`[ ]` text into table cell structures
- `test_table_checkbox_detection` (markdown) — parser events accumulate
checkbox text in table cells, confirming `replace_pending_checkbox`
detection logic
**Automated**:
- [x] `cargo test -p markdown` — 27 tests pass (26 existing + 1 new)
- [x] `cargo test -p markdown_preview` — 61 tests pass (60 existing + 1
new)
**Manual** (verified against `test-checkbox-table.md`):
- [x] Basic `[x]`/`[ ]` in a status column
- [x] Checkbox-only column alongside text
- [x] Multiple checkbox columns in one table
- [x] Left, center, and right column alignments
- [x] Uppercase `[X]` variant
- [x] Leading/trailing whitespace in cell
- [x] Checkboxes alongside other inline elements (links, bold text)
- [x] Single-column and minimal two-column tables
- [x] Normal table text unaffected by detection
- [x] List checkboxes still render correctly (regression)
- [x] Agent panel: asked agent to output table with checkbox columns
Release Notes:
- Fixed `[x]` and `[ ]` checkboxes not rendering in markdown table cells
(#50045)
* [x] Display original project name as root folder in project panel,

Add `gg`/`G` (vim), `cmd-up`/`cmd-down` (macOS), and
`ctrl-home`/`ctrl-end` (Linux/Windows) keybindings to scroll to the top
and bottom of the markdown preview.
The markdown preview already has page scroll (`ctrl-d`/`ctrl-u`), line
scroll (`ctrl-e`/`ctrl-y`), and item scroll (`alt-up`/`alt-down`) but
was missing top/bottom navigation. This adds two new actions —
`ScrollToTop` and `ScrollToBottom` — using the existing
`ListState::scroll_to()` infrastructure, following the same pattern as
the other scroll actions.
- [x] Done a self-review taking into account security and performance
aspects
Release Notes:
- Added scroll-to-top and scroll-to-bottom keybindings for markdown
preview (`gg`/`G` in vim mode, `cmd-up`/`cmd-down` on macOS,
`ctrl-home`/`ctrl-end` on Linux/Windows)

Release Notes:
- Enable parser options individually to avoid rendering issues
#50176 added `recoverable_panic` to swallow mermaid panics, then #50280
fixed it in upstream. This PR removes the workaround so future panics
reach Sentry. Also bumps `mermaid-rs-renderer` to fix a hex parsing
panic.
Release Notes:
- N/A
The mermaid renderer can fail to render certain diagrams, and we already
have a fallback for that. It's not worth crashing Zed over it.
Wrapping `catch_unwind` alone doesn't work because our panic hooks
terminate the process before unwinding begins (we intentionally
terminate so the crash handler subprocess can generate a minidump), so
there was no way to gracefully handle panics from third-party code until
now (in rare cases where we need it, like in this case).
To handle this gracefully, we added `crashes::recoverable_panic` which
tells the panic hook to stand down on the current thread so the unwind
can proceed and be caught. This should be used sparingly since caught
panics bypass crash reporting.
Release Notes:
- Fixed a crash when rendering mermaid diagrams in markdown preview.
Replaces a bunch of `impl FnMut` parameters with `&mut dyn FnMut` for
functions where this is the sole generic parameter.

This PR improves the performance of the `CopyButton` component by
tracking the copied state locally through a `CopyButtonState` struct
instead of making an OS call every time the component re-renders. Also
pushing a slight improvement here by resetting the state after two
seconds so as to make the check mark go away after you clicked to copy.
Release Notes:
- N/A
There were several places adding a copy icon button, so thought of
encapsulating the logic to copy a given string into the clipboard (and
other small details like swapping the icon and tooltip if copied) into a
component, making it easier to introduce this sort of functionality in
the future, with fewer lines of code.
All it takes (for the simplest case) is:
```rs
CopyButton::new(your_message)
```

Closes #ISSUE
Problem:
- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.
Fix:
- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

- Fix missing font features in
`git_ui::blame_ui::GitBlameRenderer.render_blame_entry`
- Fix missing buffer font features in
`markdown_preview::markdown_renderer`
- Update the way that the markdown style is built for hover popovers so
that, for code blocks, the buffer font features are used.
- Introduce `gpui::Styled.font_features` to allow callers to also set
the font's features, similar to how `gpui::Styled.font_family` already
exists.
Relates to #44209
Release Notes:
- Fixed wrong font features in Blame UI, Hover Popover and Markdown
Preview
Closes#21324
Adds four new commands:
- `markdown::MoveUp`, `markdown::MoveDown` - these scroll up and down in
markdown preview mode, by no more than the height of a large headline.
- `markdown::MoveUpByItem`, and `markdown::MoveDownByItem` - these
scroll up and down by the height of the item at the top of the markdown
preview window. So headlines and large codeblocks, for instance, scroll
further than individual paragraph lines.
Also attempts to create sensible defaults:
`down` -> `markdown::ScrollDown`
`up` -> `markdown::ScrollUp`
`alt-down` -> `markdown::ScrollDownByItem`
`alt-up` -> `markdown::ScrollUpByItem`
And in Vim:
`ctrl-u` -> `markdown::ScrollPageUp`
`ctrl-d` -> `markdown::ScrollPageDown`
`ctrl-e` -> `markdown::ScrollDown`
`ctrl-y` -> `markdown::ScrollUp`
Release Notes:
- Added commands `markdown::ScrollUp`, `markdown::ScrollDown`,
`markdown::ScrollUpByItem`, and `markdown::ScrollDownByItem`
- Changed commands `markdown::MovePageUp` to `markdown::ScrollPageUp`
and `markdown::MovePageDown` to `markdown::ScrollPageDown`
Instead of allocating a one-element vec on the heap, we can just use an
array here (since `Editor::edit` accepts anything that implements
`IntoIterator`).
I haven't checked if there are more instances that can be simplified,
just accidentally stumbled upon this when working on something else in
the markdown preview crate.

Closes#39152
This PR fixes an issue where we would render Markdown tables full width
based on their container size. We now render tables based on their
content min size, meaning you are still allowed to make the table render
as it was before by making the columns `w_full`.
I had to change the `div()` to `v_flex().items_start()` because this
introduced a weird displaying behavior of the outside table border,
because the grid container was not shrinking due to It was always taking
up the full width of their container.

Release Notes:
- Markdown Preview: Markdown tables scale now based on their content
size
This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

This PR adds support for `HTML` href elements. It also refactored the
way we stored the regions, this was done because otherwise I had to add
2 extra arguments to each `HTML` parser method. It's now also more
inline with how we have done it for the highlights.
**Small note**: the markdown parser only supports HTML href tags inside
a paragraph tag. So adding them as a root node will result in just
showing the inner text. This is a limitation of the markdown parser we
use itself.

Second take on https://github.com/zed-industries/zed/pull/37765.
This PR adds support for styling elements (**b**, **strong**, **em**,
**i**, **ins**, **del**), but also allow you to show the styling text
inline with the current text.
This is done by appending all the up-following text into one text chunk
and merge the highlights from both of them into the already existing
chunk. If there does not exist a text chunk, we will create one and the
next iteration we will use that one to store all the information on.

This PR allows you to define `align="right"` for example to change the
default alignment on **HTML** table columns. This PR also refactors
where we store the alignments in order to make it so you can define it
column based instead of only row based.
See that the `Revenue` column is left aligned instead of the default
`centered`.

Right now, we don't fill the empty column when the current row count is
less than the max row count. This PR fixes that by filling it with an
empty cell. So the table columns don't flow in the wrong direction, as
you can see inside the first screenshot.

Closes https://github.com/zed-industries/zed/issues/39837
This PR adds support for `colspan` feature that is only supported for
HTML tables. I also fixed an edge case where the right side border was
not applied because it didn't match the total column count.

Re-applies https://github.com/zed-industries/zed/pull/30840
This PR re-applies the initial
[PR](https://github.com/zed-industries/zed/pull/30840). As it was closed
because it was hard to land, because of the many conflicts. This PR
re-applies the changes for it.
In several cases we were creating multiple display_map
snapshots within the same root-level function call.
Creating a display_map snapshot is quite slow, and in some
cases we were creating the snapshot multiple times.
Release Notes:
- N/A
We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

Re-adds: https://github.com/zed-industries/zed/pull/37264
This PR re-adds basic support for showing HTML images, without touching
the display mode for images.
The initial PR changed the `div().flex().flex_col()` to
`h_flex().flex_wrap()` but this broke the text wrapping in almost all
cases.
**Note**: This does not add support for showing the images inline,
because we haven't figured out how they correctly do this.
I'm working on adding the CSS `inline` display feature support to taffy
that hopefully allows us to correctly show images/other elements inline
without breaking the text wrapping.
**Before (nightly) and after (dev) for the README file inside Zed.
(nothing has changed, which is good)**
