Smart Step Into and Safe Delete tested the text before a match with /[\p{L}\p{N}_$]$/u, which V8 in Node 26 fails for a letter outside the BMP (a lone property class before $), so smartStep.test.ts failed. Both checks now use an alternation with the same meaning.
With Mute Breakpoints on (remembered per project), every breakpoint was drawn as a hollow red circle, the disabled look. Muted breakpoints now use the grey muted icon; disabled ones keep the hollow circle. Method breakpoints and field watchpoints follow the same rule.
Inline debugger values looked up source identifiers in a plain object, so a name like toString on a nearby line resolved to an inherited Object.prototype member and crashed the editor's inline-values plugin. The execution-point subscription lived in that plugin, so after the crash the highlighted line stayed on the old position while the stack had moved on, and resume or stop did not clear it.
Locals are now kept in a prototype-free dictionary and looked up by own property, and the execution point is synced by its own plugin so an inline-value failure can't freeze it; hidden editors resync when remounted. Stepping, resume, run to cursor, reset frame and smart step clear the old execution point as soon as the request is sent, stale stack/locals responses from a previous stop are ignored, and another thread's continued event no longer clears the selected thread's execution point.
Fixes#668
While a debug session is paused, Alt/Option+click on a variable or expression runs Quick Evaluate at the clicked position (the selection when the click falls inside it) and shows the value next to it; outside a paused session Alt+click keeps its editor behaviour. The editor context menu offers Evaluate Expression… seeded with the selection or the expression at the caret while paused.
Mouse shortcuts now pass the clicked editor and position to the action, and the binding is only consumed when its action is enabled.
Fixes#664
Opening a .class file showed binary content. Class files from library jars, project output directories, navigation, Go to Class and debugger frames now all go through one route to JDT class documents:
- Library classes open the attached source, or the FernFlower decompilation when there is none, read-only and marked as decompiled. java-debug's decompiled-source support is enabled, so breakpoints set in decompiled code map to the original lines and hit, and stepping into such classes lands on the right line.
- Output-directory classes (target/classes, build/classes) open their project source when it exists; otherwise the decompiled text is shown read-only with breakpoints disabled, because jdt.ls returns no line mapping for classes outside the Java model.
- The preferred content provider id is corrected to fernflowerContentProvider (attached sources still win), and the decompiled marker recognises the current FernFlower header.
Verified on macOS with a Maven project: library class from Libraries and Go to Class, breakpoint hit and step into decompiled code, output class with and without source. Not run on Windows, Linux or Gradle projects.
Fixes#394
Settings › Debugger › Data Views gains Show value tooltip on code selection
(on by default). While the debugger is paused, selecting an expression on one
line shows its value once the selection settles, with objects expandable like
the hover tooltip.
While the debugger is suspended, hovering the start of a line shows a small
button left of its text: Run to Cursor runs to that line, and on the execution
line it resumes the program. Settings › Debugger › Show inlay Run to Cursor popup
turns it off.
Editing and folding
- Move Caret to Code Block Start / End with Selection, Auto-Indent Lines,
Move Element Left / Right (swaps call arguments, parameters and list
entries).
- Fold Code Block folds the {...} block around the caret; Expand to Level
and Expand All to Level 1-5.
- Custom folding regions (//region, #region, <editor-fold>) fold to their
description; Navigate > Custom Folding lists them.
- Error Description shows the problems at the caret; Next / Previous
Highlighted Usage steps through usage highlights.
- Editor tooltips stay below the editor's top edge, so hints on the first
lines no longer hide under the tab bar.
Navigation, project and run
- Navigate > File Path lists the file and its folders to reveal in the file
manager.
- Copy... (F5) opens the Copy dialog for the selection or the open file; the
project view's Refactor submenu gets Copy File.
- Debug... chooses a configuration to debug; Quick Evaluate Expression shows
the selection's value in an expandable hint.
- Inspect Current File runs the inspection without the scope dialog.
- Surround with Live Template lists only $SELECTION$ templates; Java gets
Callable, read / write lock and iterate templates.
Windows
- Stretch the active tool window left / right / up / down, Restore Default
Layout, Go to Next / Previous Splitter, Close Active Tab on a second key,
Stop Background Processes.
All actions have default shortcuts in both keymaps, VS Code preset entries,
main menu items and Chinese translations.
Project view and Keymap settings
- Project view Options: Sort by Name / Type / Modification Time (also in
Find Action).
- Settings > Keymap: Add Mouse Shortcut records a side-button click with
modifiers and checks conflicts like keyboard shortcuts.
- Folding: Expand to Level / Expand All to Level 1-5.
Run oxfmt once over the whole repository (formatting only, no logic changes) and add `pnpm format:check` to the frontend CI job so unformatted code no longer builds up. `.oxfmtrc.json` now skips the generated theme docs, test fixtures and code blocks inside Markdown.
Co-authored-by: jaw52 <[email protected]>
pnpm lint runs oxlint and pnpm format runs oxfmt: lint ~0.3s instead of ~20s, format check ~0.2s instead of ~11s, with far less memory. Configs come from the official migration tools (.oxlintrc.json from eslint.config.js, .oxfmtrc.json from the Prettier config); six new findings fixed or suppressed in 4 files. No code is reformatted.

Root cause: the quick-doc/problem hover and the Ctrl/⌘-hover navigation info were independent tooltips with no precedence, and the navigation modifier was only seen through the focused editor's key events, so holding Ctrl stacked both popups.
Fix: a window-wide platform navigation modifier (`src/platform/navigationModifier.ts`, ⌘ on macOS / Ctrl elsewhere, unchorded); with it held the plain hover doesn't open, late LSP results are dropped, an open hover closes (unless the pointer is inside it, so Ctrl/⌘+C still copies), release clears the link and info.
Siblings: problem/diagnostic hover, debugger value tooltip, inlay hint hovers (no doc or underline through hints, platform-correct Ctrl/⌘-click), consistent ⌘ vs ⌃ handling on macOS.
Verified in the app on macOS (⌘): hover then ⌘ leaves only the nav info, ⌘ before hover shows only nav info, release clears both and plain hover returns. Not verified on Windows.
Fixes#57https://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).

Root cause: body is user-select: none and each feature had to opt back in; the Markdown preview (and other read-only views) never did, and the app-wide contextmenu guard left no Copy item.
Fix: shared selectableText class (src/ui) for read-only content, and a fallback Copy context menu from browserGuards when right-clicking a selection or a selectable area (component menus still win).
Siblings covered: Quick Documentation / hover / completion docs, hover errors, Quick Definition, debugger value tooltip, inspection messages, message dialogs (no drag on body text), notification titles, About dialog; existing selectable consoles now get Copy too.
Verified in-app on macOS: select in Markdown preview, right-click Copy puts the text on the clipboard; tab context menu unchanged.

Alt mnemonics, search context filter (comments / string literals)
- Mnemonic bookmarks (⌥F3, ⌃⇧digit, ⌃digit), ⌘F3 bookmarks popup, descriptions,
⌘-click gutter toggles a bookmark

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.
