Adds Increase Font Size / Decrease Font Size (⌥⇧. / ⌥⇧, in the IntelliJ keymaps) for the active editor, sharing the ±1px step and limits with ⌘/Ctrl + mouse wheel. The Markdown preview, including code blocks, follows its editor's zoom, and Reset Font Size in All Editors resets it too.
Editor zoom had no effect once a font size was configured in settings: the configured size was applied with higher precedence than the zoom. The zoom now wins.

## What
An Agents feature: hand a task to a coding agent and follow it from the IDE. Agents speak the [Agent Client Protocol](https://agentclientprotocol.com). Built in: Claude Code, Codex, Gemini CLI, GitHub Copilot, Cursor, OpenCode, Qwen Code, Kimi CLI, Goose, Auggie, Kiro, Mistral Vibe. You can add your own in `<config>/agents/<id>.toml` (`name`, `command`, `args`, `[env]`). An agent whose command isn't on `PATH` is listed under "Not installed".
- **New Task page.** An editor page with a prompt box. You pick the agent, model, mode and thinking effort, and whether it runs in a new worktree (from a chosen branch) or in the checkout.
- **Agents tool window.** Tasks are grouped by what they need: Needs Input, Failed, Running, Ready to Review, Archived. It also shows a stripe badge, a status bar item and notifications.
- **Session tab.**
- The conversation: Markdown, thinking, tool calls with diff stats, the plan.
- Permission requests appear as an editor banner.
- The changed files are compared against the task's base commit and open in the diff viewer.
- A context-usage meter.
- **Composer.**
- `@` references files from the project index. A referenced file's text is sent when the agent accepts embedded context, otherwise a `resource_link`.
- `/` lists the agent's commands; ↑/↓ recall earlier messages.
- Images can be pasted, dropped or picked; Shift+Tab cycles the mode.
- While the agent works, Enter queues the message and ⌘↵ interrupts the turn and sends it now. Queued messages can be sent now, edited or removed.
- **Send to Agent.** In the editor and Project view context menus. It adds `@file:10-20` references to the message you typed last.
- Landing the work is left to the existing Git features: the worktree is a normal branch.
## How
- **`crates/ide-agent`**: one ACP agent process per task, running in the task's directory.
- It folds `session/update` into a timeline and answers `session/request_permission`.
- It tracks the session's settings: `configOptions`, falling back to the older `modes` / `models` fields. The user's choices are applied again on every new or reloaded session.
- Tasks are saved as JSON per task. Sessions resume with `session/load` without duplicating history, and old task files are upgraded when read.
- **`ide-jsonrpc`**: adds newline-delimited framing (ACP) next to Content-Length (LSP).
- **`ide-vcs`**: adds `numstat_with_worktree` for the changes list.
- **Editor**:
- The Switcher (⌃⇥) lists every open editor, as IDEA does, not just files.
- `EditorKindContribution.restorable` lets a kind's tabs be saved with the editor session, so agent tabs survive reloads.
- **UI**: `Select` popups now size to fit short option details (they used to cut them off).
## Testing
- `cargo test -p ide-agent` (14 tests). They use an in-memory ACP agent and cover permissions, restart with `session/load`, settings, the queue with send-now and stop, and prompt blocks.
- There is also an ignored end-to-end test against the real Claude Code adapter: `OPENIDEA_AGENT_E2E=1 cargo test -p ide-agent real_claude -- --ignored`.
- `pnpm vitest run`: 2052 tests.
- `cargo clippy -p ide-agent -p openidea --all-targets -- -D warnings` and typecheck are clean.
- Driven in the running app with Claude Code:
- A task in a worktree, with permission answers, changes listed and the diff opened.
- A follow-up after restarting the IDE.
- `@` reference with embedded content, `/` commands, Shift+Tab mode changes.
- A queued message and send-now, an image prompt, Send to Agent from a selection.
- The Switcher and restored tabs after a reload.
Not covered yet: only Claude Code was driven end to end. The other agents go through the same ACP path but weren't run here.
Merged on the maintainer's go-ahead. Merge with main: kept both sides in Cargo.toml (ide-agent + ide-clipboard), the feature registry (agents + vim) and zh.json (no duplicate keys). After the merge: typecheck clean, full vitest 268 files / 2247 tests passed, ide-agent/ide-jsonrpc/ide-vcs 144 passed, bindings unchanged after regeneration.
Two editor toggles under Settings › Editor › Color Scheme › Language Defaults (off by default, also actions `editor.toggleRainbowBrackets` / `editor.toggleSemanticHighlighting`):
- Semantic highlighting (IDEA's rainbow variables): locals and parameters coloured by a name hash from LSP semantic tokens; fields, statics, constants, library symbols untouched.
- Rainbow brackets (VS Code's bracket pair colorization): (), [], {} by depth, unmatched in the error colour, strings/comments skipped, visible ranges only with 4 KB checkpoints.
Palettes are theme tokens (`--syn-rainbow-1..5`, `--syn-bracket-1..3`, light/dark/high-contrast), editable in the Color Scheme tree, and mapped from IntelliJ `.icls` RAINBOW_COLOR1..5.
App verification on macOS found the colours were overridden by the syntax highlighter's span nested inside the marks; the rules now cover descendants. Verified both toggles on/off live in a TS file.
Fixes#56https://claude.ai/code/session_01VUYsdXA2nkF5v6zsC93dpn
Root cause: the editor had no font weight settings, and the WebView rendering of JetBrains Mono looks lighter than IDEA (#32).
Fix (IDEA's Settings › Editor › Font › Typography Settings): configurable Main font weight and Bold font weight (defaults Regular 400 / Bold 700) via --fw-code / --fw-code-bold; colour-scheme bold/regular overrides still win; settings preview updates live. Replaces the Light-only 450/550 hard-coding.
Siblings covered: sticky lines, diff/merge, run console (ANSI bold), Find in Files, completion/parameter info/docs, database editor, debugger value popup, matched braces, terminal with "Use editor font".
Verified: scoped vitest, ide-core tests, in-app on macOS (settings UI, editor weight follows the setting end to end).
Claude-Session: https://claude.ai/code/session_01VUYsdXA2nkF5v6zsC93dpn
Root cause: the terminal built its own font-family ("JetBrains Mono", Nerd Fonts, monospace) without the bundled "JetBrains Mono Variable", so on Windows (no JetBrains Mono installed) xterm fell back to the system monospace (SimSun on Chinese Windows); xterm also measured cells before the webfont loaded.
Fix: one resolver (src/platform/fonts.ts monoFontFamily) maps JetBrains Mono to the bundled face; xterm re-measures once fonts load; "Use editor font" also takes the editor's fallback font (IDEA).
Siblings covered: embedded run terminal, editor default family + fallback, Settings › Editor › Font preview.
Verified in-app on macOS (terminal renders JetBrains Mono Variable). Not verified on Windows.

* feat: Second pass aligning interactions with IntelliJ IDEA
Result tool windows
- Next/Previous Occurrence (⌥⌘↓/↑) across Find, Usages, Problems, TODO,
Inspection and Hierarchy, with an "N of M" status hint
- Find: reuse the unpinned tab, Pin Tab, source preview, group by file or
directory, exclude moves to the next result, Rerun
- Usages: tabs with pinning, exclude and preview
- Problems, TODO, Inspection: no autoscroll by default, severity-first sorting,
context menu with quick fixes and copy description
- Trees: F4/⌘↓ jump to source; speed search Home/End and arrow handling
Find in Files, bookmarks, navigation
- Replace mode: Enter replaces the selection, ⇧⌥Enter replaces all, multi-select
- Pin Window toggle, highlighted read-only preview, search/replace history (⌥↓),
Alt mnemonics, search context filter (comments / string literals)
- Mnemonic bookmarks (⌥F3, ⌃⇧digit, ⌃digit), ⌘F3 bookmarks popup, descriptions,
⌘-click gutter toggles a bookmark
- Select In popup (⌥F1); Recent Locations double-click and Delete;
Search Everywhere remembers the query per tab
Code insight and refactoring
- Extract/Introduce continue with in-place rename and name suggestions;
expression and occurrence choosers with live highlighting
- Safe Delete confirms first; numbered Refactor This
- Quick Documentation history, in-popup links and a Documentation tool window;
Quick Definition switches between targets and shows the whole declaration
- Goto chooser lists symbol names and can pin to the Find window
- Parameter Info Tab/⇧Tab, intention preview, Reformat dialog and summary,
inlay hint ⌘-click and context menu
- Live templates: Enter moves to the next field, two-step Esc, ⌘J as a lookup,
language surrounders with mnemonics
- File Structure popup as a filterable tree; Show Usages filter and preview;
call hierarchy jumps to call sites
Editor
- Paste re-indents each line by default; Move Statement moves whole statements
in and out of blocks and re-indents
- Type over closing quotes of existing strings; ⌘D/⌘⌫ cover folded regions;
⌥⌫ deletes the preceding word
- ⌃G / ⌃⌘G whole-word rules and wrap hint; double-modifier caret cloning
- Visual-column block selection, nested Collapse All, recursive folding,
fold selection toggle, Go to Matching Brace, gutter drag selects lines,
sticky line and error stripe clicks, Insert toggles overwrite mode
Run, VCS, workbench
- Gutter icons show the last test result; Modify Run Configuration; test tree
hides passed tests, context menu and assertion diff
- Stack frames resolve by fully qualified class name; context run chooser
- Inline Smart Step Into
- Git Log multi-select filters, "me" and date range; favourite branches,
Fetch and tags in the branch popup; stash Keep index and Unstash options
- Terminal tab titles follow the shell; Distraction Free persists; gear menu;
sticky balloons move to the notifications tool window after a while
* fix(vcs): Label restored local changes as yours after Smart Checkout; name the branch checked out
Conflicts from restoring stashed changes show the user's uncommitted
changes on the left like other operations, and the checkout notification
names the new branch instead of the previous one.
* fix: Close the merge editor on Apply; confirm before terminating a running Run tab
Like IDEA, applying a merge result closes its tab, and closing a Run tab
whose process still runs asks before terminating it (with a Settings
toggle and "Do not ask again").
* fix(terminal): Don't start a new session in the background after closing the last tab
The hidden Terminal window stays mounted, so it reopened a session as soon
as the last tab closed. It now opens the Local tab only once the window is
shown again, as IDEA does.
* fix(vcs): Start the merge result from a three-way merge; close the editor on Apply
The result pane now begins with non-conflicting changes merged and each
conflict showing the base text, resolved from the side panes, instead of
raw conflict markers. Apply now reports success, so the tab closes.
fix(search): Match File Structure filter on word starts
* fix: Limit Smart Step Into to the paused line; drop usages hints on callbacks; show full intention titles
Adapters that list every remaining call in the function (debugpy) made Smart
Step Into fall back to a chooser that offered calls from later lines. Targets
are now narrowed to the calls on the paused line, so they are picked in place.
Anonymous functions and callbacks no longer get a 'no usages' hint, and
intention titles are no longer cut short when there is room for them.
* fix: Undo / Redo from the Edit menu and Find Action use the editor's history
They ran the webview's native undo, which misses programmatic edits such as
templates, completion and refactorings, so nothing happened in the editor.
* feat(nav): Complete file paths and flag unresolved web file references
Path completion in href/src/url()/@import, Markdown links and path-like strings, folders first. HTML and CSS paths that name no file get a 'Cannot resolve file' warning. File references resolve in the backend like IDEA's: relative to the file, /-rooted against the project and resource roots.
* feat: Align editor, workbench, run/debug and VCS interactions with IntelliJ IDEA
Keymap
- Let AltGr characters through instead of firing Ctrl+Alt shortcuts (Windows/Linux)
- Double Shift: strict press/release timing, ignored while typing or after Shift+click
- Chords wait 2s and swallow an unmatched second stroke
- Drop CodeMirror defaults that clash with IDEA keys; ⌘Enter is Split Line, add
Scroll to Center and Code Block Start/End
- Add missing IDEA defaults (⌃J, ⌘Y, ⇧⌘C, ⌥⌘Y, ⇧⌘M, F9 Resume, ⌘R Rerun, …)
Editor
- Tab inserts at the caret; smart Backspace to the proper indent; Enter continues
a `//` comment; per-language line comment placement
- Back/Forward records navigations only; ⌘F searches the selected text
- In-place rename; ⌃Space inserts a sole candidate; commit characters only for a
focused lookup; usage highlighting survives edits; ⌥Enter offers fixes from the
caret line; ⌘-hover shows declaration info only for navigable targets
Workbench
- Tool windows: primary and split area per side, six Move To anchors, layout migration
- ⌘W closes tool window content; Shift+Esc from the editor; closing a tab
activates the left neighbour; preview tab and tab limit follow IDEA defaults
- Switcher lists open editors and tool windows; Recent Files Delete removes items
- Search Everywhere tab/scope behaviour; popups close when the window deactivates
- Project view: Copy/Move dialogs on paste, skippable usage search on delete,
new-file input cancels on blur; Settings search Esc clears the filter
- Status bar breadcrumbs open a children popup; notification timeouts
Run / Debug / Build / Terminal
- Run asks to stop a running single-instance config; Rerun restarts silently;
"Allow multiple instances" option
- Run chooser: Enter runs, Shift debugs, F4/Delete/digits
- Type into the console for stdin; Stop covers debug sessions
- Log (Shift+click) and temporary (Alt+click) breakpoints; independent suspend/log
options; Evaluate prefill and history; changed-value highlighting; expandable hints
- Build window opens on failure and jumps to the first error
- Terminal confirms closing a busy tab and lets IDE shortcuts through
VCS
- Correct ours/theirs labels during rebase, cherry-pick and revert
- Smart/Force Checkout; remote branch checkout updates the local branch
- Partial commit by changed block; inline before-commit check results
- F7 continues into the next file; Rollback Lines; Commit and Push; Amend message swap
- Branch delete with Restore; force push confirmation; editable push target;
update summary with the incoming commits
* chore: Regenerate bindings
- Project widget initials follow IDEA's AvatarUtils.initials ("idea" → "I").
- "Show directories with changed descendants" is off by default, as in IDEA.
- FileEntry gains `excluded`: only excluded folders get the excluded icon and
dimming; git-ignored ones keep the plain icon and the ignored colour.
- `.github` folders get IDEA's GitHub folder icon.
- Matched tag names are never bold and use their own background
(MATCHED_TAG_NAME); matched braces are bold in dark schemes only.
- Revert Greyscale antialiasing to `antialiased` for UI and editor; `auto`
rendered text heavier than PyCharm.
Claude-Session: https://claude.ai/code/session_01SaPPsVPuk6ZTNsoUCNCbMv
- ide-web: built-in static server on 127.0.0.1 that serves project files,
plus detection and launching of installed browsers.
- Open In › Browser in the editor, project view and tab menus; browser bar
and built-in preview beside HTML editors; ⌃⇧R opens the default browser.
- Emmet: Tab expansion in markup editors and Update Tag with Emmet.
Claude-Session: https://claude.ai/code/session_01SaPPsVPuk6ZTNsoUCNCbMv
Greyscale antialiasing mapped to `-webkit-font-smoothing: antialiased`,
which drops macOS stem darkening, so editor and UI text rendered thinner
and syntax colours looked lighter than PyCharm's. Use `auto` instead.
Align lezer tag mappings with PyCharm's Light scheme:
- HTML/XML: `<!doctype>` is plain text (documentMeta is a sub-tag of meta).
- CSS/SCSS/Sass: property names use the attribute colour; values and units
the attribute-value colour; class, id, pseudo, colour and url() the tag colour.
- YAML: keys are keywords.
- Markdown: quotes are strings with keyword markers, link destinations
italic function colour, titles strings, horizontal rules keywords.
Claude-Session: https://claude.ai/code/session_01SaPPsVPuk6ZTNsoUCNCbMv
Right-click on the gutter now shows Annotate with Git Blame, Add/Remove
Bookmark, Soft-Wrap, Configure Soft Wraps, an Appearance submenu and
Configure Gutter Icons, contributed through a new "editorGutter" menu
group. A breakpoint line still opens the breakpoint popover.
Elixir files opened as plain text: highlighting only came from
@codemirror/language-data, which has no Elixir mode. Grammars now carry
their own highlights.scm; `doc_highlights` folds its captures into a small
kind vocabulary (inner nodes and later patterns win, interpolation clears
the string colour), memoised per document version on the incremental
tree. The editor maps kinds onto Lezer tags, so colours follow the active
scheme, and requests them only when no CodeMirror mode exists.
Enabled for Elixir; other grammar-only languages need their query wired.
Claude-Session: https://claude.ai/code/session_01B65qLEKnkeYTGdbwhLpjCu
Message dialogs: `Dialog` gets an `icon` (question / info / warning / error)
that renders IDEA's alert layout: no title bar, a 32px icon, bold title,
text, checkbox under it. Every confirmation helper (prompt, VCS, services,
project tree, keymap, LSP choices, run, database, Replace All) uses it. Open
Project matches IDEA: "This Window" is the default and has focus. The Code
Analysis and TODO commit checks default to Review.
Project widget: the title bar project button opens a popup like IDEA's
ProjectWidget, with Open… / Clone Repository…, the projects open in other
windows (new `window_open_projects` command) and recent projects, filtered by
typing.
Chinese UI: UI text stays written in English and is translated through a
source-text catalog (`locales/text/zh.json`, about 2300 strings). The UI
primitives (buttons, checkboxes, selects, tabs, dialogs, menus, tooltips,
toasts, settings labels and hints) translate the strings they are given.
Action titles and categories are localised in the registry, and static JSX
text uses `<T>`, so text follows a locale switch without a reload. The
Settings window now syncs the locale too. Settings search matches both
languages.
Claude-Session: https://claude.ai/code/session_01B65qLEKnkeYTGdbwhLpjCu
Name patterns the IDE treats as nonexistent (.DS_Store, __pycache__, *.pyc, VCS dirs, ...) were hard-coded in five places, and Git changes ignored none of them, so .DS_Store showed up as unversioned. files.ignoredNames (IDEA's default list) now drives the project view, navigation bar, index, watcher, Find in Files, inspections and the Git status.
Opening another project in the same window left the previous project's state in
module-level stores: Amend and the commit message carried over, debug sessions kept
running, and Git Log, usages, hierarchy, inspection, HTTP client, recent locations,
navigation history and notifications still showed the old project.
Reset each of them on a project root change, stop the old debug sessions, ask about
unsaved changes before leaving a project, close the settings window (it would apply
to the new project) and end the indexing task when a scan is cancelled.
