Warya Wayne 3bd398582f markdown_preview: Show link destinations on hover (#60942)
# Objective

Markdown Preview does not reveal where a link will navigate before it is
opened or right clicked to copy the URL.

Show a small Firefox-style URL preview in the bottom-left corner when
hovering text links or linked images.

## Solution

- Added URL hover reporting to the Markdown renderer, including hit
detection for linked images that are outside the text layout.
- Used the existing `LinkPreview` component to display the hovered
destination in the bottom-left corner of the Markdown preview.
- Cleared the destination preview when the pointer leaves a link, the
preview, or the displayed Markdown changes.

## Testing

- Confirmed the project builds successfully and manually verified the
behavior on macOS.
- Hovered text links and linked images in a Markdown preview and
confirmed their destinations appear in the bottom-left corner.
- Moved the pointer away from links and outside the preview and
confirmed the destination preview disappears.
- Reviewers can test this by opening a Markdown file containing a text
link and a linked image, opening its preview, and hovering each link.

Smit Barmase 8f907c5ee1 markdown: Improve selection copying to always yield valid markdown (#60657)
Closes https://github.com/zed-industries/zed/issues/59083
Closes https://github.com/zed-industries/zed/issues/42958
Closes https://github.com/zed-industries/zed/issues/59612

This PR improve selection copy of Agent Panel and Markdown Preview such
that copied text is always valid markdown, following how VSCode handles
it. The partial selection of styled text would not copy broken syntax
like `bold**` or ```inline code` ``` like before.

Now we follow simple rule:

> Selecting any part, no matter from where, copies it as its markdown.
Except when the selection sits entirely inside a single inline code
span, in which case we copy plain text, for terminal and code use cases.

Examples:

This is **bold** text, this is *italic* text, and this is `code` all `in
one` sentence.

- selecting only bold → `**bold**`
- selecting normal text and partial bold → `is is **bo**`
- selecting a single code span completely → `code`
- selecting partial code → `od`
- selecting partial text and code → `` his is `cod` ``
- selecting multiple code spans partially → `` `ode` all `in o` ``
- selecting multiple code spans end to end → `` `code` all `in one` ``

Nested spans, like **bold with `code` inside**:

- partial text in bold → `**ld wi**`
- partial code in bold → ``**`od`**``
- full code in bold → ``**`code`**``
- the whole sentence → ``**bold with `code` inside**``

Links, like [Visit Rust's website](https://rust.org):

- partial link text → `[bsite](https://rust.org)`
- full link text → `[Visit Rust's website](https://rust.org)`

How it works:

Selection boundaries that land inside delimiter syntax (`**`, backticks,
etc.) first snap out so no delimiter is left half-selected. Then any
spans the selection cuts through get their delimiters re-added,
outermost first, so nested styling stays balanced. Only the root blocks
containing the two selection boundaries are inspected, everything in
between is copied right as is, which also keeps this cheap on large
documents.

Release Notes:

- Improved copying selected text in Agent Panel and Markdown Preview.
Partial selections of styled text now copy as well-formed markdown, and
selections within a single inline code span copy as plain text.

Warya WayneandSmit Barmase 7d545c0bae markdown: Make linked images clickable (#59525)
# Objective

Make images nested inside markdown links (e.g., README badges)
clickable, so they behave like normal markdown links.

Previously, linked images rendered correctly but were not interactive in
markdown previews: they did not show a pointer cursor, could not be
clicked to open their target URL, and did not expose link actions
through the context menu.

## Solution

Changed the `MarkdownElement` to detect when an `<img>` tag is inside a
`<a>` tag during rendering. When a linked image is rendered:

- The wrapper `div` gets a `cursor_pointer` style and an `on_click`
handler that opens the link URL (or delegates to the `on_url_click`
callback if set).
- The wrapper also captures right-click events to populate the context
menu with "Copy Link" via `capture_for_context_menu`.
- The `on_url_click` closure type was changed from `Box<dyn Fn>` to
`Rc<dyn Fn>` to allow cloning across multiple handlers.
- When a linked image fails to load, the fallback element's `on_click`
now calls `cx.stop_propagation()` to prevent the event from bubbling to
the parent link wrapper and opening the URL twice.

The feature is gated behind `!self.style.prevent_mouse_interaction` so
it respects existing interaction-prevention settings.

## Testing

- `cargo test -p markdown`: 95 tests passed.
- Manually verified in markdown preview that badge/image links open
correctly and right-click shows "Copy Link".
- Verified existing markdown tests continue to pass.

Danilo Leal 995e56d263 markdown_preview: Use UI font for base font size (#60212)
This PR makes the `markdown_preview_font_size` setting be based on the
UI font size instead of the buffer UI font size. I typically use a much
smaller code font than UI font, and that made reading the markdown
preview super small. I don't think this will be uncommon because the
dimensions between mono and non-mono typefaces are different...

Release Notes:

- Changed the markdown preview to fall back to the UI font size instead
of the buffer font size when `markdown_preview_font_size` is unset.

90587dd639 Keep inline code pipes inside markdown table cells (#57744)
## Summary

Fixes markdown table rendering when inline code spans contain pipe
characters. Code such as `` `a|b` `` and `` `a||b` `` now stays in one
table cell instead of being split into extra columns.

## Why

Agent output and markdown previews can include regexes, shell snippets,
and other code spans with `|` characters inside tables. Before this
change, those pipes could be parsed as table delimiters even though they
were part of inline code.

## Changes

- Masks raw pipes only inside matched inline code spans before
`pulldown-cmark` parses tables.
- Restores rendered code-span text from the original source range,
including escaped table pipes.
- Avoids masking unmatched backticks, fenced code blocks, indented code
blocks, and invalid fence closers.
- Adds parser and renderer coverage for raw pipes, escaped pipes,
unmatched inline code, invalid fences, and code-span link callbacks.

Manual check: generated agent responses across multiple models render
tables containing `` `a|b` ``, `` `(a|b)` ``, and `` `a||b` `` as single
code-span cells rather than split columns.

David AlecrimandSmit Barmase 46ff888db8 markdown_preview: Add font size settings and actions (#55489)
Add support for scaling the Markdown preview's body text and headings
with `cmd-=` / `cmd--` / `cmd-0`. Previously these shortcuts only
resized code blocks because the preview's body used `ui_font_size` and
headings used a rem-based scale anchored to it, while the keybindings
only mutated `BufferFontSize`.

The preview's scroll subtree is now wrapped in
`WithRemSize(buffer_font_size)`, so `1rem` resolves to the buffer font
size inside the preview. Body text, headings
(`text_3xl`/`text_2xl`/...), and rem-based spacing all scale together.
The outer focus root and scrollbar remain at the UI font size.

David AlecrimandSmit Barmase 5a5242ffeb markdown: Render inline <br> tags as line breaks (#54165)
## Summary
Inline `<br>` tags in markdown (e.g. `<br>`, `<br/>`, `<br />`) were
rendered as literal text instead of line breaks when images are around.
VS Code and GitHub both treat them as hard line breaks.

The fix has two layers:

**Parser (`parser.rs`):** The text-merge loop was consuming `InlineHtml`
events as empty text. `<br>` variants are now excluded from that loop
and converted to `HardBreak` events instead, matching the semantics of a
trailing two-space or backslash line break in CommonMark.

**Renderer (`markdown.rs`):** Image paragraphs use a flex row layout, so
text `\n` has no effect. `HardBreak` inside an image paragraph now
inserts a `div().w_full().h_0()` child, which forces a flex-wrap row
break. Images also get `mr_2()`/`mb_2()` margins for spacing, replacing
the previous `SoftBreak`-as-space hack. `SoftBreak` is suppressed inside
image paragraphs to avoid phantom whitespace elements disrupting the
flex layout.

Dan DascalescuandBennet Bo Fenner 10628c3d2c agent_ui: Add in-thread search bar (#57231)
This is a narrower alternative to #54816, scoped to search only the
currently-loaded thread, excluding tool output or thinking blocks (happy
to follow up on those, see next). It uses a custom bar confined to
`agent_ui` rather than `BufferSearchBar` + `SearchableItem`, avoiding
the cross-crate plumbing that #54816 reached. Open as draft pending
direction from @benbrandt on what scope/approach would be acceptable for
in-thread search.

src="https://github.com/user-attachments/assets/8971e432-61d3-46db-a6a4-2bbd355089e7"
/>


## What this PR does

Adds a search bar to the agent panel, triggered by Ctrl+F (Cmd+F on
macOS), that lets users grep the currently-loaded thread without leaving
the agent panel; not cross-thread or cross-agent.

- Searches visible content only: user messages, assistant message
chunks, and tool-call labels. Thought blocks and rendered tool-call
content (collapsed by default) are intentionally skipped so that:
  1. The visible match count matches what the user sees.
2. The search experience is consistent between tool output blocks in the
current Zed session, ans tool output blocks from past sessions, which
are not rendered - see issue #57230
- Highlights matches inline via `Markdown::set_search_highlights` for
markdown-rendered content and
`Editor::highlight_background(HighlightKey::BufferSearchHighlights, …)`
for past user messages (rendered through `MessageEditor`'s inner
`Editor`, not through markdown).
- Next/prev navigation, case/whole-word/regex toggles (same UI as
`BufferSearchBar`).
- Returns focus to the message editor on dismiss so the user can keep
typing immediately.

<details><summary>Commits (authored by Claude 4.7 Opus, max)</summary>

### Seven logical commits

1. **`agent_ui: Add in-thread search bar`** — initial implementation:
bar UI, keymap bindings under `AcpThreadSearchBar` context, markdown
highlight plumbing, focus-restore on dismiss.
2. **`agent_ui: Add unit tests for in-thread search`** — coverage of the
matcher across entry kinds and the dismiss-clears-highlights path.
3. **`agent_ui: Limit search to visible tool-call text`** — UX fixes
from manual testing: `track_focus` so `AcpThreadSearchBar` context lands
in the editor's dispatch chain; red border on zero-match query; skip
tool-call content (only search labels).
4. **`agent_ui: Fix Esc dispatch, smart toggle, error message, skip
Thought blocks`** — round 2 of UX fixes: contribute `AcpThreadSearchBar`
context from `ThreadView` when bar is visible, smart Ctrl/Cmd+F
outside-the-bar focuses instead of closing, regex error message row,
skip `AssistantMessageChunk::Thought`.
5. **`agent_ui: Polish thread search bar — Esc routing, user-message
highlights, action forwarding`** — `search::*` action forwarders on
`ThreadView`; `cx.defer` around the activate callback (fixes a
double-borrow panic); `editor::actions::Cancel` interception so Esc
dismisses our bar instead of escaping to the workspace's
`BufferSearchBar`; user-message highlights via the inner `Editor`; muted
zero-match counter; three new gpui regression tests.
6. **agent_ui: Fix Shift+Enter shadowing in thread search bar`** —
capture-phase intercept of `editor::Newline*` on the bar's `bar_row`
element so a base keymap binding `shift-enter` at the `Editor` context
(e.g. JetBrains → `editor::NewlineBelow`) can't shadow the bar's
`agent::SelectPreviousThreadMatch`. Adds a regression test that loads
`default-linux.json` + `linux/jetbrains.json` and asserts `shift-enter`
navigates instead of inserting a newline.
7. `agent_ui: Debounce thread search, refresh on thread changes,
highlight user messages`** — last round before maintainer review: 150 ms
debounce on the match rescan; subscribe to `AcpThread` updates so
results/highlights/counter follow a streaming conversation live;
navigate the list to the entry owning the active match; `.ok()` instead
of `let _ =`; assorted cleanups; two new regression tests
(`test_thread_search_refreshes_on_new_thread_entry`,
`test_thread_search_scrolls_to_later_user_message_match`).
</details>

8 gpui tests cover the load-bearing logic (`cargo test -p agent_ui --lib
-- thread_search`). All pass.

## Manual testing

Verified on Linux against `upstream/main` `13e7c11768` (full `release`
profile, with LTO and `codegen-units=1` built and tested at that
commit). Branch since merged with `upstream/main` `a6780a5`. Of the 100
intervening upstream commits, several touch files in this diff; one
produced a real conflict in `crates/agent_ui/src/conversation_view.rs`
(`gpui::{...}` import block — both sides added new, non-overlapping
symbols; resolved by union).

- Bar opens / dismisses via Ctrl+F and Esc
- Next/prev navigation via Enter / Shift+Enter / F3 / Shift+F3 / chevron
buttons
- Case / whole-word / regex toggles via buttons and via Alt+C / Alt+W /
Alt+R (Linux)
- Highlights inside past user messages render correctly on the
`MessageEditor`'s inner `Editor`
- query text turns red on no-match; bad regex shows error message;
zero-match counter stays muted (not red)
- `search::*` actions fire from outside the bar (focus in message
editor) via the `ThreadView`-level forwarders
- Workspace pane `BufferSearchBar` is unaffected; the two bars hold
independent state
- Feature looks great in light mode and dark mode, and with various
themes
- Navigating to a match in a past user message scrolls that message into
view (its top to the viewport top)
- Results update live as the agent streams new messages while the bar is
open (debounced ~150 ms, same for typing)

updates.webm](https://github.com/user-attachments/assets/75585fee-ba25-42ac-9dde-16c8e152fb06)

<details><summary>Full manual test plan</summary>

### Setup (preconditions for every test below unless otherwise noted)

1. Launch the dev binary: `./target/release-fast/zed --user-data-dir
~/.local/share/zed-dev-feat`
2. Open the agent panel, start a thread, send 2–3 prompts so the thread
contains:
- At least one user prompt with a distinctive substring (e.g.
`watermelon`)
   - At least one assistant message with a distinctive substring
   - At least one tool call with a known label substring
   - At least one collapsed Thinking block
3. In parallel: have at least one code editor open in a workspace pane
(some tests cross-check that path).

### Core matching

#### T-001 — Ctrl+F opens the bar with focus in query

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** With focus in the agent panel's message editor, press Ctrl+F
(Linux) / Cmd+F (macOS). The search bar appears at the top of the thread
view and the query input is focused.

#### T-002a — Active match visually distinct from inactive matches

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** Type a query that produces ≥3 matches. The current ("active")
match must be visually different from the others — different highlight
color, not just position. If they look identical, this may be a theme
issue (`search_active_match_background` vs `search_match_background` too
close on the entry's background); note the theme.

#### T-002b — User-prompt text gets inline highlight, not just match
count

**Status:** ✅ PASS 2026-05-15 17:15 (fix shipped 2026-05-15 16:15;
regression-guarded by
`test_thread_search_highlights_user_message_editor`)

**Repro:** Send a user prompt containing a distinctive substring. Then
search that substring. The user prompt text **must** show yellow
highlight, not just be counted. The bar's matcher reads from
`message.content.markdown()` but the on-screen render goes through a
`MessageEditor`; the current code only highlights via
`Markdown::set_search_highlights`, which misses the editor.

**Notes:** Fix routes user-message matches through
`Editor::highlight_background(HighlightKey::BufferSearchHighlights, …)`
— the same path `Editor`'s own `SearchableItem` impl uses.
`collect_markdowns` no longer pulls the user message's markdown
(avoiding double-counting). The bar now maintains separate
`highlighted_markdowns` and `highlighted_editors` lists for clean-up.
Match-target enum (`MatchTarget::Markdown` vs `MatchTarget::Editor`)
tags each match so active-vs-inactive re-paint can dispatch correctly.
Pending runtime verification on next `release-fast` build.

#### T-003 — Enter / Shift+Enter in bar navigates matches

**Status:** ✅ PASS 2026-05-25 14:00 (verified on `release` build)

**Repro:** With focus in the query, type a query with ≥3 matches. Press
Enter → counter `1/N → 2/N → 3/N`. Press Shift+Enter → reverses (and no
`\n`s are output in the search box). F3 / Shift+F3 same.

### Option toggles

#### T-004 — Alt+C toggles case sensitivity from inside bar

**Status:** ✅ PASS 2026-05-15 07:50

**Repro:** With focus in query, press Alt+C. `Aa` button toggles state;
results re-filter.

#### T-005 — Alt+W toggles whole-word from inside bar

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** Same as T-004, with Alt+W toggling `wd` button.

#### T-006 — Alt+R toggles regex from inside bar (Linux)

**Status:** ✅ PASS 2026-05-15 15:30 (fix shipped 2026-05-15 06:35)

**Repro:** Press Alt+R. `.*` button toggles.

**Notes:** macOS keymap (`alt-cmd-x`) left unchanged in this session —
it matches the wider macOS Zed convention.

#### T-006a — Tooltips on toggle buttons show their hotkey

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** Hover each toggle button (`Aa`, `wd`, `.*`). Tooltip shows
action name AND keybinding (e.g. "Toggle Case Sensitive · Alt+C").

### Error / empty states

#### T-007 — Empty matches: no red border on bar input

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** Type `zzzzzzz`. Query text turns red. Counter shows `0/0`.
Bar input border stays **neutral**, no red box.

#### T-008 — Bad-regex error message

**Status:** ✅ PASS 2026-05-15 15:30 (error renders aligned with the
input)

**Repro:** Switch to regex mode, type `[`. Error message appears below
bar, aligned with the input.

#### T-019 — Zero-match counter not colored red

**Status:** ✅ PASS 2026-05-15 15:30 (fix shipped 2026-05-15 06:30)

**Repro:** Type a query with no matches. The counter (`0/0`) stays
muted, **not** red. MPS-parity.

### Dismissal & re-entry

#### T-009 — Esc doesn't interrupt agent generation

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** Start a long prompt; while the agent is generating, open the
search bar and press Esc. Bar closes, generation continues.

#### T-010 — Close-X button position

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** Look at the bar. Close (X) button is on the right side, after
the nav arrows (`<` `>` `1/N` `X`). NOT free-floating left of the input.

#### T-011 — Ctrl+F in bar selects all query text

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** With bar open and query containing text, press Ctrl+F. All
query text becomes selected (next keystroke replaces).

#### T-012 — Ctrl+F outside the bar (bar already open) does not crash

**Status:** ✅ PASS 2026-05-15 15:30 (fix shipped 2026-05-15 06:30;
regression-guarded by
`test_thread_search_select_next_from_thread_view_update_does_not_panic`)

**Repro:** Bar visible, focus in the message editor (not the bar). Press
Ctrl+F. Bar gets re-focused, query text is selected. **Must not crash.**

**Notes:** Original crash also reproducible from Enter / Shift+Enter
inside the bar after a search had matches. Fix wraps the
`on_activate_match` callback's `view.update` in `cx.defer`.

#### T-021 — Esc dismisses agent bar (not the unrelated workspace pane's
BufferSearchBar)

**Status:** ✅ PASS 2026-05-15 15:30 (fix shipped 2026-05-15 14:40;
regression-guarded by `test_thread_search_editor_cancel_dismisses_bar`)

**Repro:** Open a file in a workspace pane editor (e.g.
`settings.json`). Open BufferSearchBar there. Switch focus to the agent
panel, open agent search bar, type a query. Press Esc. **The agent bar
must dismiss; the workspace pane's BufferSearchBar must remain.**

**Notes:** Root cause: `Editor::cancel` in single-line mode calls
`cx.propagate()`. The propagated `editor::actions::Cancel` walked past
our bar all the way to `Workspace`, where `BufferSearchBar::register`
had registered a workspace-wide handler that dismissed the active pane's
bar. Fix: `ThreadView` now catches `editor::actions::Cancel` when the
bar is visible.

### Action routing while bar is open, focus is in the message editor

#### T-013 — F3 / Shift+F3 from outside the bar

**Status:** ✅ PASS 2026-05-15 15:30 (Enter from outside is *expected*
not to work — message editor's `enter` binding outranks. F3 is the
canonical out-of-bar nav key.)

**Repro:** Bar open with matches, focus in message editor. Press F3 →
next match. Shift+F3 → previous.

#### T-014 — Alt+C / Alt+W / Alt+R from outside the bar

**Status:** ✅ PASS 2026-05-15 15:30 (fix shipped 2026-05-15 02:30;
`ThreadView` forwarders for `search::ToggleCaseSensitive`,
`ToggleWholeWord`, `ToggleRegex`, `FocusSearch`)

**Repro:** Bar visible, focus in message editor. Alt+C/W/R toggles the
bar's options and re-runs search.

### Nav buttons

#### T-022 — `<` / `>` chevron buttons in the bar advance match

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** With ≥2 matches, click `<` → previous. Click `>` → next.
Wraps at ends.

### Coexistence with workspace-pane buffer search

#### T-015 — Ctrl+F in a workspace-pane editor still opens
`BufferSearchBar` (no agent-panel takeover)

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** Focus a code editor in a workspace pane, press Ctrl+F. The
pane's `BufferSearchBar` opens as before; agent panel's bar does NOT
open.

#### T-016 — Independent bars: agent vs workspace pane

**Status:** ✅ PASS 2026-05-15 15:30

**Repro:** Have both bars open simultaneously. They hold independent
state (different queries, different toggles, independent dismissal).

### Tool-call content (auto-expand on match)

#### T-017 — Auto-expand collapsed tool calls on match

**Status:** ⏸️ BLOCKED (not implemented; out of scope for current
session)

**Repro:** Have a tool call whose collapsed content contains a unique
substring. Search that substring. The tool call auto-expands so the
match is visible. After dismissal, the tool call collapses again unless
the user manually expanded it before.

#### T-018 — Auto-expand collapsed Thinking blocks on match

**Status:** ⏸️ BLOCKED (not implemented; out of scope for current
session)

**Repro:** Same shape as T-017 for a collapsed Thinking block.

#### T-019 — Streaming results automatically highlighted / live thread
search

**Status:** ✅ PASS 2026-06-08

**Repro:** Send prompt "Write a 5-paragraph story about a researcher who
hated noise. The last paragraph should be a one-sentence: "So she moved
to <name of the quietest continent on Earth>" (replace that <name> with
the actual name)", then search for `Antarctica`.
</details>


## Known limitations

1. (pre-existing, not from this PR): search highlights inside markdown
table cells can be visually offset by a few characters in columns
starting with the second. The bug lives in `crates/markdown`'s render
layer - see issue #57229
2. (excluded vs. #54816 to keep the scope tight): raw tool-call
input/output JSON and terminal scrollback are not indexed.
3. Navigating to a search hit located **below the fold of a very long
user message** highlights the match but only scrolls the message's top
into view, so the hit can stay off-screen until you scroll manually.
Past user messages render through an `AutoHeight` `Editor` inside a
virtualized `List`, which can't reliably drive intra-entry autoscroll
the way markdown content does. User messages are usually shorter than a
viewport, so this is left unaddressed.
4. Plain-text search across triple-backtick fences does not match (the
fence characters live in the markdown source; regex search with explicit
fence handling does).
5. The literal text "Thinking" rendered as the thought-disclosure header
is not searchable (rendered chrome, not markdown source).

Bennet Bo Fenner 92399c67a1 markdown: Add debug_asserts for search result ordering (#59483)
Follow up to #59473

The previous code could actually highlight the wrong match if you passed
in unordered ranges.
However, i realized that all codepaths are passing in ordered matches
already, so I just added some `debug_asserts` to ensure that this is
always the case.

Bennet Bo Fenner c7ad65e468 markdown: Optimize paint_search_highlights (#59473)
Follow up to #52502

This fixes a severe hang in the markdown preview when searching for text
caused by `paint_search_highlights`. We were iterating over all lines
for each highlight, and for each highlight we called
`layout.line_layout_for_index` which internally would iterate over all
the lines of the text layout.

With this optimisation we paint all highlights in one pass. We sort the
highlight ranges, iterate through the lines and only access
`WrappedLineSegments` when we actually have a highlight in that line.

E.g. if you copy this text
(https://gist.github.com/bennetbo/e313f3023da9fec42e090177a5373152) into
the editor, open the markdown preview and search for `codex` Zed Nightly
will completely freeze. After this optimisation it is totally smooth
even in debug mode.



Release Notes:

- Improved performance when searching in markdown preview

Ted RobertsonandSmit Barmase fe22af1e6e markdown: Render soft breaks as line breaks in agent markdown (#57376)
Agents sometimes output status lists with bullets represented by emojis
- see #57372. These currently get rendered on one line, as opposed to
bullet items like `-` or `*`, because single newlines within a paragraph
are collapsed into spaces - standard CommonMark soft-break behavior *in
prose* contexts (e.g. `README.md`). But in *comment/PR* contexts, GitHub
preserves these newlines:

✅ Did A
✅ Did B
✅ Did C

Users reasonably expect agent output to be rendered following the
comment-style convention.

## What this PR does

This PR adds a `soft_break_as_hard_break: bool` field on `MarkdownStyle`
and enables it for `MarkdownFont::Agent`, so a single newline within a
paragraph *in agent output* renders as a line break instead of a space.
The field defaults to `false` to preserves CommonMark behavior
everywhere else. In `themed_with_overrides`, sets it to `true` for
`MarkdownFont::Agent`. The rendering switch in
`MarkdownElement::request_layout` then emits `"\n"` instead of `" "` for
`MarkdownEvent::SoftBreak` when the flag is set. This matches GitHub
comments and Obsidian default behavior, and prevents emoji + trailing
newline content from being collapsed onto a single line in agent
responses.

Scoped strictly to `MarkdownFont::Agent`. Hover popovers, diagnostics,
markdown preview, README rendering, etc. are all untouched.

Remco Smits 735980b158 markdown: Fix text selection position in centered/right-aligned markdown table cells (#57283)
Table header cells are always center-aligned. When selecting text in
them, the selection highlight was drawn at the left edge of the cell
instead of over the actual visible text. Clicking on a character also
mapped to the wrong source index.

The bug was that `bounds_for_source_range` and
`source_index_for_position` used raw layout x-coordinates (which start
at 0), without accounting for the horizontal offset GPUI applies when
rendering center- or right-aligned text.

The fix stores the `TextAlign` on each `RenderedLine` at flush time,
then uses it to compute an alignment offset per wrapped row segment.
That offset is:
- subtracted from the click position before resolving it to a source
index
- added to the x-coordinates when computing selection highlight bounds

Smit Barmase f0ed342c19 markdown: Add frontmatter metadata block rendering (#57845)

while more complex metadata falls back to a code-style block.
- Metadata block content and key/value rows are parsed in the parser
step, and the request layout simply takes over rendering.

63f725e8d6 markdown: Merman (#57644)
Big PR that replaces `mermaid-rs` with `merman`.

Adds a new crate `mermaid_render` that exposes a simple API for
rendering a mermaid diagram to an SVG string.

## Why is it so big?

Some of this is explained in the crate-level docs for `mermaid_render`,
but the short version is:
- `mermaid-rs` emits "good enough" SVGs for most use cases. It also
ships with a reasonable default theme
- `merman` emits *very accurate* SVGs, but with borderline unusable CSS
- Most of the new code in this PR are a series of passes to clean up the
output SVG by:
  - Injecting good CSS
  - Fixing issues in the `merman`-generated SVGs
- Tweaking the final result to avoid issues with `usvg` and `resvg`,
which are what will eventually be used to rasterize the SVG
- This code *could* be much smaller, but the following design decisions
made it take a lot more code:
  - Using a real XML parser instead of basic string manipulation
  - Avoiding allocating strings in as many places as possible

Because of this, the design is as follows:
- First, construct a `merman` theme from the user's theme, and render
the mermaid to an SVG string
- Post-process - each step is roughly a `fn(Iterator<Item =
Event<'short>>) -> Iterator<Item = Event<'short>>`, where `Event` is the
type for events produced by `quick-xml` (a pull-based XML parser)
 

## Note for reviewers

It's a big diff, sorry 😅 happy to pair review. 

The new crate is essentially a leaf crate - it does technically depend
on `gpui`, but only for the `Hsla` and `Rgba` types. Extracting a new
`gpui_color` crate felt like overkill for this already-very-big PR.

Each post-process pass is in its own submodule, and has a doc comment
explaining the before/after. Note that bugs in this code are perhaps
less serious than bugs in other parts of the code:
- The code has been thoroughly audited for potentially-panicking code
paths - as far as I know, there are none (excluding some `.expect()`s on
calls to `write!` with `String`, which is [cannot return `Err`][string
write])
- A bug in this code (given that it will not cause a panic) will, at
worst, result in an invalid diagram being rendered, or simply falling
back to showing the code.
- The current `mermaid-rs` renderer *already* does this in quite a lot
of cases, sometimes showing outright misleading information.

MartinYe1234andzed-zippy[bot] cfd0461b5a Prefix read_file tool output with line numbers (#56779)
Format `read_file` tool output in `cat -n` style: each line is prefixed
with its line number right-aligned in a 6-character field, followed by a
single tab, followed by the line's original content (newlines preserved,
including CRLF). Numbering reflects the actual file lines, so a ranged
read starting at line 42 emits `42` for its first line, not `1`.

For large files, content returned by `get_buffer_content_or_outline` is
**not** prefixed:

- The symbol outline path already conveys structure via its `[L100-150]`
annotations.
- The truncated first-1KB fallback (used when a file exceeds
`AUTO_OUTLINE_SIZE` and has no parseable outline) is wrapped in a
synthetic `# First 1KB of …` header, so its lines don't correspond to
real file line numbers.

Both cases are reported via `BufferContent::is_synthetic` (renamed from
`is_outline`).

Also updates the `edit_file` tool's input doc to describe the prefix
format and tell the model to strip it before constructing `old_text` /
`new_text`, preserving the original indentation that appears after the
tab.

Updates how we render `read_file` tool call outputs in the UI
(screenshots included in comments below).
Also fixes an existing bug where `read_file` tool call outputs would not
re-render their content code block when an older thread was restored
(the tool's `replay` hook was missing).

Closes AI-226

Release Notes:

- Improved how `read_file` tool output renders in the agent panel, with
a line-number gutter, and fixed it not re-rendering on restored threads

MartinYe1234 f78f6da255 Make file paths in backticks clickable in agent panel (#57303)
When the agent mentions a file path inside `backticks` (e.g. ``
`src/main.rs` `` or `` `src/main.rs:42` ``), the rendered code span now
becomes a clickable link in the agent panel. Clicking opens the
referenced file in the workspace, jumping to the right line and column
when present.

## How it works

- **Shared path resolution.** Extracted `OpenTarget` and the
workspace/worktree resolution logic out of
`terminal_view::terminal_path_like_target` into a new
`workspace::path_link` module so both the terminal and the agent panel
can use the same code. Includes a `sanitize_path_text` helper ported
from the terminal's URL/punctuation handling. Pure refactor — terminal
behavior is unchanged.
- **`markdown` crate hook.** Added
`MarkdownElement::on_code_span_link(callback)`. When the callback
returns `Some(url)` for a given code span's contents, the existing
`push_link` machinery wires up cmd-hover, hit testing, and the existing
`on_url_click` callback. When it returns `None`, the code span renders
as before. The hook is opt-in, so `markdown` stays workspace-agnostic.
- **Agent panel wiring.** `render_agent_markdown` constructs an
`AgentCodeSpanResolver` that snapshots the project's visible worktree
entries plus their file extensions. `try_resolve` does a cheap
synchronous heuristic check (path must contain `/`/`\` or end in an
extension present in the workspace, can't be a URL, can't be all digits,
etc.) and then looks the candidate up in the per-worktree
`HashSet<Arc<RelPath>>`. On a hit it returns a `MentionUri::File` or
`MentionUri::Selection` URI, which the existing `thread_view::open_link`
already knows how to open at the right line.

## Edge cases handled

- Code spans inside fenced code blocks stay plain (gated on
`builder.code_block_stack.is_empty()`, matching how regular markdown
links behave).
- Trailing prose punctuation (`` `src/main.rs.` ``) is stripped before
lookup.
- Identifiers like `` `String` ``, `` `await` ``, `` `npm run dev` ``
stay plain — they don't pass the path-like heuristic.
- Cross-platform path separators handled via the per-worktree
`PathStyle`.

## Tests

- `crates/markdown` — unit test asserting code spans become links when
the callback returns `Some`, and stay plain when it doesn't.
- `crates/agent_ui` — unit test for `AgentCodeSpanResolver::try_resolve`
covering hits with and without a `:line` suffix, misses, identifiers,
and trailing punctuation.
- Existing `terminal_view` tests cover the moved resolution code
(unchanged behavior).

## Notes

- There's currently a temporary `log::info!` in
`AgentCodeSpanResolver::try_resolve` that reports per-call worktree-walk
timing and a cumulative total. Kept in for now to verify the feature
isn't being called excessively during streaming renders. Can be removed
before merge.
- Resolution is sync-only against worktree entries; absolute paths
outside the workspace are not resolved (would require an async re-render
path).

Closes AI-277

Release Notes:

- Made file paths in `backticks` clickable in the agent panel; clicking
opens the referenced file at the given line when present.

MartinYe1234 33eb2d83ed Skip syntax highlighting for read_file outline responses (#57287)
When `read_file` returns a file outline instead of full contents, the
result is now wrapped in a plain fenced code block rather than tagging
it with the file's path.

Previously, the outline was wrapped in a fenced block tagged with the
file path (e.g. `` ```crates/agent/src/tools/read_file_tool.rs ``).
Because the tag contains a slash, the markdown parser routed it through
`CodeBlockKind::FencedSrc`, resolved the file's language by path, and
ran the language's tree-sitter parser against the outline on every
paint. The outline is structural (e.g. `fn foo [L10-20]`), not actual
source for the file's language, so the parse was both expensive and
produced incorrect highlighting.

Because GPUI rebuilds the visible element tree on every window paint,
anything that triggers a repaint (cursor blink in the focused message
editor, animations, the turn timer, etc.) would re-run the tree-sitter
parse on the entire outline, throttling the frame rate while the tool
call was expanded.

This change adds an `is_outline_response` flag in `ReadFileTool::run`
and, when set, passes an empty tag to `MarkdownCodeBlock` so the
renderer sees `CodeBlockKind::Fenced` (no language). Plain monospace
formatting is preserved; the path tag is still used for the non-outline
(full file) case.

Adds two regression tests: one asserting the outline path uses an
untagged fenced block, and one asserting the full-file path keeps the
path tag (so the next person fixing this doesn't accidentally strip the
tag everywhere).

Also includes a small markdown-rendering follow-up:
`MarkdownElementBuilder::push_text` was recomputing the base text style
(cloning `base_text_style` and walking the style stack) twice per
highlighted token. For a code block with hundreds of highlight tokens,
that's hundreds of redundant `TextStyle` clones per paint. The style
stack does not change while runs are being attributed, so the style is
now computed once outside the loop and reused.

Closes AI-234

Release Notes:

- Improved scrolling smoothness in the agent panel when a `read_file`
tool call with a large file outline is expanded.

Danilo Leal 0042fb5850 markdown: Add ability to wrap/unwrap codeblock content (#57312)
This PR adds an icon button to Markdown codeblocks allowing to control
whether or not the content should be wrapped. At the moment, this is not
hard-persisted, meaning that 1) wrapping text in one codeblock instance
does not affect others, and 2) the codeblock will be reset every time
its view is recreated (i.e., closing and opening a Markdown Preview tab,
an agent thread, etc.). I intentionally kept it simple just to see how
it feels, but we can certainly consider a setting later on.

alkinun c0596fade7 markdown: Fix escaping non-ASCII chars (#55782)
Fixes #55704

The `escape` function in `crates/markdown/src/markdown.rs` was calling
`c as u8` on the `char`s before passing to `MarkdownEscaper::next()`.
This strips non ASCII Unicode codepoints down to just their low 8 bits
which might be in the ASCII punctuation range and thus cause an extra
backslash to be added in front of these non ASCII chars.
 
Release Notes:

- Fixed a bug where non-ASCII chars in diagnostic messages were
incorrectly rendered with spurious `\` characters

Lee Nussbaum 003e821177 markdown_preview: Independent code font family (#56744)
Adds a `markdown_preview_code_font_family` setting that overrides the
font used in the markdown preview for code — inline `code` spans and
fenced code blocks.
This is the counterpart to `markdown_preview_font_family` (#54003),
which already does this for body text. Together they let you choose a
typographically matched body + code font pair for the preview without
forcing the code font onto editor buffers, where it may not be a good
coding font:

```json
{
  "markdown_preview_font_family": "Noto Serif",
  "markdown_preview_code_font_family": "Noto Sans Mono"
}
```

Behavior mirrors `markdown_preview_font_family`:
- Scoped to the markdown preview only (`MarkdownFont::Preview`). The
agent panel, notifications, hover popovers, and REPL output are
unaffected — they keep using the buffer font for code.
- Falls back to the buffer font family when unset, so existing previews
are unchanged.
- Overrides the font family only; fallbacks and features still come from
the buffer font.

Smit Barmase 6151889ddf markdown: Fix table header alignment and apply alignment to cell content (#56179)
Follow up: https://github.com/zed-industries/zed/pull/53465

For Markdown tables, headers are now always centered (ignoring column
alignment), matching standard Markdown rendering behavior. For HTML
tables, headers default to center but respect explicit `align`
attributes.

This also propagates alignment to paragraphs and headings inside table
cells, not just the cell container itself.

David AlecrimandSmit Barmase e6b8b30e22 markdown: Improve table cell alignment (#53465)
## Summary

Markdown preview tables kept text pinned to the top of a row when a
neighboring cell contained a taller image. This made mixed
text-and-image tables look unbalanced and inconsistent with common
editor behavior. This change makes table text stay visually centered
within taller rows so Markdown tables are easier to scan and match
expected rendering more closely.

iam-liamandLukas Wirth 1b37531a2e markdown: Make table cell checkboxes clickable (#54747)
Closes #53587

Follow-up to #50595.

[#50595](https://github.com/zed-industries/zed/pull/50595) added
display-only checkboxes when `[x]` / `[X]` / `[ ]` appears as the sole
content of a markdown table cell. That PR called out interactivity as a
later step — this PR delivers it.


https://github.com/user-attachments/assets/c666ee4c-7e31-4450-ab33-c07c82949818

## What this does

When a consumer of `MarkdownElement` supplies an `on_checkbox_toggle`
callback, table-cell checkboxes now invoke it on click with the source
range of the `[x]` / `[ ]` marker and the new checked state. This
mirrors the existing list-item checkbox path.

For markdown preview (`markdown_preview_view.rs`) the callback is
already wired to edit the source buffer, so clicking a checkbox in a
previewed `.md` file now flips `[x]` to `[ ]` and back in the file, the
same as it already did for list checkboxes.

## How it works

`replace_pending_checkbox` previously took the cell's outer source range
and always built a visualization-only checkbox. It now takes the
optional toggle callback instead, and reconstructs the marker's exact
source range from `pending_line.source_mappings` — pulldown-cmark emits
`[x]` in a table cell as three separate `Text` events, so the per-chunk
mappings are needed to recover the 3-character range to rewrite. If a
callback was supplied, the checkbox attaches an `on_click` that invokes
it with that range and `!checked`; otherwise it falls back to the prior
visualization-only rendering.

Two free helpers (`source_range_for_rendered` /
`source_index_for_rendered`) were extracted so the mapping logic is
unit-testable.

## Scope

One file: `crates/markdown/src/markdown.rs`. No changes to
`markdown_preview` — since #52008 it renders through the shared
`MarkdownElement`, so its existing `on_checkbox_toggle` wiring picks up
table checkboxes for free.

## Relation to #53587

[#53587](https://github.com/zed-industries/zed/issues/53587) reports
that markdown checkboxes in the **agent panel** can't be clicked. This
PR is a necessary piece of that fix — without it, even if the agent
panel wired `on_checkbox_toggle`, its table checkboxes would stay inert.
It does not fully close #53587 on its own: the agent panel's
`MarkdownElement` instances in `conversation_view.rs` / `thread_view.rs`
don't currently wire `on_checkbox_toggle`, and wiring it there requires
deciding how clicks should mutate the in-memory agent response (no
source file to edit into). That's a follow-up.

## Test plan

**Unit tests** (2 new, both in `crates/markdown/src/markdown.rs`):
- `test_table_checkbox_marker_source_range` — walks parser events for a
table with checkboxes, replays what the builder accumulates, and asserts
the reconstructed source range slices to exactly `[x]` / `[ ]` in the
original markdown (including a padded-whitespace case).
- `test_source_range_for_rendered_handles_split_chunks` — pins the
mapping helper against the three-chunk layout pulldown-cmark produces.

**Automated**:
- [x] `cargo test -p markdown` — 46 tests pass (44 existing + 2 new)
- [x] `cargo test -p markdown_preview` — 3 tests pass
- [x] `./script/clippy -p markdown` — clean

**Manual** (against a preview of a markdown file with checkbox tables):
- [x] Click a checked `[x]` table cell — it becomes `[ ]` in the source
and rerenders as unchecked
- [x] Click an unchecked `[ ]` — becomes `[x]`
- [x] Uppercase `[X]` toggles on click (replacement writes `[x]` / `[
]`, matching the list-item behaviour)
- [x] Padded-whitespace cells still target just the three marker
characters
- [x] Multiple checkbox columns in one table all independently clickable
- [x] Alignment variants (left/center/right) behave the same
- [x] Non-checkbox table text unaffected
- [x] List-item checkboxes continue to work (regression)

Release Notes:

- Made table-cell markdown checkboxes clickable in markdown preview,
matching list-item checkbox behavior

Follow up to https://github.com/zed-industries/zed/pull/54374 as that
removed the custom heading styles that were mostly tailored to the agent

that we can set it conditionally to just the agent context.

robinojwandChris Biscardi a1cb3706f4 markdown_preview: Independent font family and theme (#54003)
## Summary

Adds two user-facing settings that let the markdown preview render with
a font family and theme independent from the editor. Both are optional
and fall back to the editor defaults when unset.

```json
{
  "markdown_preview_font_family": "Georgia",
  "markdown_preview_theme": "Solarized Light"
}
```

## Details

- New `MarkdownFont::Preview` variant, used only by the preview surface.
- New `MarkdownStyle::themed_with_overrides()` that accepts explicit
`ThemeColors` and `SyntaxTheme` so the preview can render with a theme
other than the active editor theme. Existing `themed()` callers are
unchanged.
- The preview pane background adopts the chosen theme's
`editor_background`.
- Follows the pattern already used by `agent_ui_font_size` /
`agent_buffer_font_size`.

## Scope

Sizing-related changes (`markdown_preview_font_size`,
`markdown_preview_line_height`, typography tweaks, responsive max-width
container) were in an earlier revision of this PR and have been removed
per review feedback — they interact with the Cmd+/- zoom behavior in
ways that still need design work, and will land in a follow-up.

## Files Changed

- `crates/settings_content/src/theme.rs` — schema
- `crates/theme_settings/src/settings.rs` — runtime + accessor
- `crates/markdown/src/markdown.rs` — `MarkdownFont::Preview` +
`themed_with_overrides()`
- `crates/markdown_preview/src/markdown_preview_view.rs` — theme
resolution, style selection, background
- `crates/markdown_preview/Cargo.toml` — `theme` dependency
- `crates/settings/src/vscode_import.rs` — new fields in struct literal

Release Notes:

- Added `markdown_preview_font_family` and `markdown_preview_theme`
settings to customize the markdown preview independently from the
editor.

Kento Yamamoto 14f0a254eb markdown: Apply theme syntax color to inline code in rendered markdown (#54475)
## Summary

Inline code in rendered markdown previously used only the default
foreground color with a subtle background tint, which made it visually
indistinguishable from surrounding prose in some themes.

This change looks up the `text.literal` syntax style from the active
theme and applies its color to inline code, matching the treatment used
for inline code elsewhere in the editor (e.g. syntax highlighting in
source buffers). When the theme does not define `text.literal`, the
color falls back to the previous default.

saberoueslati d2ddb4b2d9 markdown: Fix heading sizes and spacing in preview (#54374)
## Context

Heading sizes in the markdown preview were nearly identical to body
text, making `# H1`, `## H2`, and `### H3` visually indistinguishable.
The root cause was in `MarkdownStyle::themed()`: it set a
`heading_level_styles` override with font sizes of `rems(1.05–1.15)`,
which silently replaced the correct sizes applied by
`apply_heading_style` (via GPUI's `text_3xl`/`text_2xl`/`text_xl`
utilities `rems(1.875/1.5/1.25)`). Removing that override restores the
intended hierarchy. A `mt_4()` top margin was also added so consecutive
headings have visual breathing room.

Closes #54358

## How to Review

`crates/markdown/src/markdown.rs` Three changes:
- (1) removed the `heading_level_styles` block from
`MarkdownStyle::themed()` that was overriding heading font sizes with
nearly-body-text values;
- (2) added `mt_4()` to the heading div in `push_markdown_heading` for
better vertical spacing;
- (3) added `test_heading_font_sizes_are_distinct` which renders H1–H3
and a paragraph then asserts that line heights strictly decrease from H1
down to body text.

saberoueslati 481407479d markdown: Add "Copy Link" to right-click context menu (#53758)
## Context

Closes #53741

Right-clicking on a link in any Markdown view showed no way to copy the
URL. The right-click handler already detected links for left-click
navigation, but the context menu was never extended to surface a
link-specific action.

Video of the manual test below :

## How to Review

- **`crates/markdown/src/markdown.rs`** — Added a `context_menu_link:
Option<SharedString>` field to `Markdown`. Added
`capture_for_context_menu(link)` (replaces the old
`capture_selection_for_context_menu`) which saves both selected text and
the hovered link together. Added a `context_menu_link()` accessor.
Updated the capture-phase right-click handler to detect the link under
the cursor via `rendered_text.link_for_source_index`. Added a
`event.button != MouseButton::Right` guard to the bubble-phase
`MouseDownEvent` handler to prevent selection logic from running on
right-click.

- **`crates/agent_ui/src/conversation_view/thread_view.rs`** — In
`render_message_context_menu`, after computing `has_selection`, also
reads `context_menu_link` from the same markdown chunks. Adds a "Copy
Link" entry with a separator at the top of the menu when a link URL is
present.

- **`crates/markdown_preview/src/markdown_preview_view.rs`** — Wraps the
markdown element in a `right_click_menu` with a "Copy Link" entry (when
a link is present).

Edit: There was a mention of a "Copy" and "Copy as Markdown" buttons.
After discussion, it was decided that I would re-add them fully fleshed
out in a separate PR

David AlecrimandSmit Barmase 0ddc7d0666 Fix crash and enable GIF animation in markdown preview (#53459)
Closes #53426

Fixes a crash when previewing markdown with GIFs, and enables GIF
animation in the preview panel.

Two issues: a partially-decoded GIF could crash the preview, and GIFs in
markdown previews never animated.

The fix for GIFs with empty comment extensions (`21 fe 00`) was
implemented upstream in the `image-gif` crate (image-rs/image-gif#228)
and released as `gif 0.14.2`. This PR bumps the dependency so those GIFs
now render correctly in the markdown preview without any further changes
to Zed itself.

GIFs.

DongandSmit Barmase a151def86f markdown_preview: Add footnotes support (#53086)
## What does this PR changed

Adds footnote rendering and navigation to Zed's markdown preview.

- **Footnote references**: (`[^1]`) render inline as `[1]` with link
styling (color + underline)
- **Footnote definitions**: (`[^1]: ...`) render at the bottom with a
horizontal separator, smaller text (85% size), and a label prefix
- **Click-to-navigate**: clicking a footnote reference scrolls to its
definition


https://github.com/user-attachments/assets/a79a0136-f22d-40ac-8b53-cfefa8573d21

## OOS/ Need discussion

- **Display style**: Since currently the gpui crate does not provide a
superscript style, in this PR we publish the feature with using
[`[1]`]() instead of aligning to the GFM styled[^1]
- **Footnote definition placement**: GFM renders the footnote at the
bottom of the content no matter where the user place the footnote
definition, but the `pulldown_cmark` renders the footnote just at where
user place it, for this PR I'll keep the footnote where `pulldown_cmark`
renders it, and we may have some more discuss on if we need to move them
to the bottom of the markdown preview

[^1]: GitHub-flavoured markdown

## What to test

- [ ] Open a markdown file with footnotes (e.g. `Text[^1]\n\n[^1]:
Definition`)
- [ ] Verify reference renders as `[1]` with link color
- [ ] Verify definition renders below a separator with smaller text
- [ ] Verify pointer cursor appears on hover over `[1]`
- [ ] Verify clicking `[1]` scrolls to the definition
- [ ] Verify normal links still work as before
- [ ] `cargo test -p markdown` passes (46 tests)

Release Notes:

- Added support for footnotes in Markdown Preview.

Angel P.andSmit Barmase 614f67ed2a markdown_preview: Fix HTML alignment styles not being applied (#53196)
## What This PR Does
This PR adds support for HTML alignment styles to be applied to
Paragraph and Heading elements and their children. Here is what this
looks like before vs after this PR (both images use the same markdown
below):

```markdown
<p style="text-align: center;">
  <a target="_blank" href="https://github.com/"><img width="150" height="150" src="https://upload.wikimedia.org/wikipedia/commons/c/c2/GitHub_Invertocat_Logo.svg"></a>
</p>
```

**BEFORE:**

<img width="742" height="242" alt="image"
src="https://github.com/user-attachments/assets/4ca8b8d9-0606-45f5-8a0e-cafaaac47d97"
/>

**AFTER:**

<img width="1274" height="267" alt="image"
src="https://github.com/user-attachments/assets/2c347ce7-75b9-4ef6-9598-b1eda7272ef5"
/>

## Notes
I used `style="text-align: center|left|right;"` instead of
`align="center|right|left"` since `align` has been [deprecated in
HTML5](https://www.w3.org/TR/2011/WD-html5-author-20110809/obsolete.html)
for block-level elements. The issue this PR solves mentioned that github
supports the `align="center|right|left"` attribute, so I'm unsure if the
Zed team would want to have parity there. Feel free to let me know if
that would be something that should be added, however for now I've
decided to follow the HTML5 standard.

Ahmet Kaan GümüşandConrad Irwin fd4d8444cf markdown_preview: Add search support to markdown preview (#52502)
Context

The markdown preview had no search functionality — pressing Ctrl+F did
nothing. This PR implements the SearchableItem trait for
MarkdownPreviewView, enabling in-pane text search with match
highlighting and navigation.

  Changes span four crates:

- project: Added SearchQuery::search_str() — a synchronous method to
search plain &str text, since the existing search() only works on
BufferSnapshot.
- markdown: Added search highlight storage to the Markdown entity and
paint_search_highlights to MarkdownElement. Extracted the existing
selection painting into a reusable paint_highlight_range helper to avoid
duplicating quad-painting logic.
- markdown_preview: Implemented SearchableItem with full match
navigation, active match tracking, and proper SearchEvent emission
matching Editor behavior.
- Keymaps: Added buffer_search::Deploy bindings to the MarkdownPreview
context on all three platforms.
  
The PR hopefully Closes
https://github.com/zed-industries/zed/issues/27154

  How to Review

1. crates/project/src/search.rs — search_str method at the end of impl
SearchQuery. Handles both Text (AhoCorasick) and Regex variants with
whole-word and multiline support.
  2. crates/markdown/src/markdown.rs — Three areas:
    - New fields and methods on Markdown struct (~line 264, 512-548)
- paint_highlight_range extraction and paint_search_highlights (~line
1059-1170)
    - The single-line addition in Element::paint (~line 2003)
3. crates/markdown_preview/src/markdown_preview_view.rs — The main
change. Focus on:
- SearchEvent::MatchesInvalidated emission in schedule_markdown_update
(line 384)
    - EventEmitter<SearchEvent> and as_searchable (lines 723, 748-754)
- The SearchableItem impl (lines 779-927), especially active_match_index
which computes position from old highlights to handle query changes
correctly
  4. Keymap files — Two lines each for Linux/Windows, one for macOS.
