- Line 84: Update OutlineFragment.onDocumentChanged so the
FileManager.getDocumentContents fallback runs off the main thread when
event.newText is null, while keeping the direct event.newText path unchanged and
applying the resulting content through the existing UI-safe update flow.
- Around line 78-86: The onDocumentChanged handler currently processes snapshots
for inactive documents, allowing the OutlineViewModel to diverge from the active
editor. Before calling OutlineViewModel.onSnapshot, return unless
event.changedFile matches the file associated with getCurrentEditor(); preserve
existing snapshot behavior for the active document.
In `@app/src/main/java/com/itsaky/androidide/utils/EditorSidebarActions.kt`:
- Around line 279-283: Replace the android.util.Log usage in
EditorSidebarActions with an SLF4J logger obtained via
LoggerFactory.getLogger(EditorSidebarActions::class.java), using {} placeholders
and passing any throwable as the final argument. Preserve the separately
generated stack-trace string for PluginCrashedEvent.
In `@app/src/main/java/com/itsaky/androidide/viewmodel/OutlineViewModel.kt`:
- Around line 51-56: Update the snapshots collector in OutlineViewModel so the
complete compute flow, including OutlineProvider.supports(), is wrapped in
exception handling; preserve cancellation by rethrowing CancellationException
while catching non-cancellation failures so the collector continues processing
later snapshots.
- Around line 96-98: Update the OutlineFragment snapshot producers for document
events, document selection, and document closure to pass a normalized full-path
key instead of only Path.fileName or File.name, while retaining the basename
separately for display. Update OutlineViewModel’s collapsedForFile comparison
and assignment to use that stable path-based key so collapse state is reset only
when the actual file changes.
In
`@editor/src/androidTest/java/com/itsaky/androidide/editor/language/outline/TreeSitterOutlineQueryTest.kt`:
- Around line 46-48: Update the query-loading expression in
TreeSitterOutlineQueryTest to wrap the reader returned by open(...).reader() in
use { }, ensuring the asset reader and underlying stream close after readText()
completes.
In `@editor/src/main/assets/editor/treesitter/kt/outline.scm`:
- Around line 26-27: Update the class_parameter query so `@symbol.property` is
emitted only for constructor parameters explicitly declared with val or var,
excluding bare parameters such as name: String. Add positive regression cases
for val and var properties and a negative case for an unmodified constructor
parameter.
In
`@editor/src/main/java/com/itsaky/androidide/editor/language/outline/TreeSitterOutlineProvider.kt`:
- Around line 88-92: Update the asset-reading flow in loadQueries around the scm
assignment to wrap the Reader in use { }, ensuring it closes after readText()
completes or throws while preserving the resulting query text.

…line Review follow-ups from CodeRabbit on #1804: - OutlineFragment ignores DocumentChangeEvents for files other than the active editor's, so an edit to a background tab no longer swaps the outline away from the file navigateTo targets. The event always carries the new text (IDEEditor posts it), and the active editor's buffer is the fallback, so the main-thread FileManager disk read is gone. - Snapshots are keyed by normalized absolute path instead of basename, so two Main.kt files in different modules no longer share collapse state. - The snapshot collector catches non-cancellation failures around the whole computation (supports() included), so one bad file cannot stop later refreshes. - kt/outline.scm lists a class_parameter as a property only when it is declared val or var; class Repo(name: String) no longer shows "name". The instrumentation fixture gains a plain parameter that must not appear. - Asset readers for outline.scm are closed after reading (provider and query test). Not changed: the android.util.Log calls in EditorSidebarActions predate this branch and are outside its scope.

Review of ADFA-2448 (outline sidebar)
Reviewed at 13e960cd. The design is sound and the unit-test work is genuinely good -- OutlineViewModelTest covers debounce coalescing, Loading-on-switch, collapse persistence across a re-parse, and the failing-supports recovery path; OutlineTreeBuilderTest pins the containment-stack edge cases including equal start offsets. Ticket requirements 1-4 are all implemented: tree view, document-order sort in OutlineTreeBuilder, click-to-navigate via OutlineUiEffect.NavigateTo, and refresh on both change and file switch.
Findings: 2 IMPORTANT, 4 MINOR, 2 NITPICK, all posted inline. Both IMPORTANTs are concurrency/interaction defects in code this PR adds, not style.
Previous round: all 8 bot comments carry an "Addressed in commit 13e960c" marker. Seven are genuinely fixed, one is not.
Verified by reading the code at head, not by trusting the marker:
- Inactive-document snapshots -- fixed.
OutlineFragment.kt:82now returns unlessnormalized(file.toPath()) == normalized(event.changedFile). - Main-thread
FileManager.getDocumentContents-- fixed. That call is gone; the fallback iseditor.text.toString(), in-memory, andIDEEditoralways populatesnewTextanyway (IDEEditor.kt:1292), so the fallback is unreachable. - Collector dies on a
supports()throw -- fixed.OutlineViewModel.kt:59-65wrapscomputeand rethrowsCancellationException, anda failing supports check does not stop later snapshots from refreshingpins it. - Basename collapse key -- fixed.
Snapshotcarries a normalized absolutepathwithfileNamederived from it, all three producers passnormalized(...), and there is a regression test. - Unclosed asset reader, both sites -- fixed.
TreeSitterOutlineProvider.kt:91andTreeSitterOutlineQueryTest.kt:48both use.use { it.readText() }. class_parameterwithoutval/var-- fixed.kt/outline.scm:27gates on["val" "var"], and the provider test covers both signs viaclass Repo(val name: String, tag: String).android.util.LoginEditorSidebarActions-- not fixed, and out of scope. Those calls are still at lines 279-301, butgit show origin/stagehas them at 266-286: they are pre-existing and this PR only reindented them. The marker is wrong. Nothing to do here; see the MINOR on the mixed reformat, which is what made this code look new.
Findings without a diff anchor
MINOR: the PR description is empty. No summary, no ADFA-2448 link, and no statement that the screen was checked at font scale 1.0 and 2.0. CLAUDE.md requires that font-scale line for any new or changed screen, and the repo convention is that a PR links its ticket. The outline panel is a new screen with a LazyColumn of text rows, so it is squarely in scope. I could not verify 2x myself -- that needs a device -- which is why the missing statement matters rather than being a formality.
Evidence ledger
| Area | Result |
|---|---|
| Ticket completeness | ADFA-2448 requirements 1-4 mapped to code + test; tooltip pending per the ticket's own comment |
| Exceptions | compute and the collectLatest body both catch and rethrow CancellationException; nothing new reaches the global handler |
| Threading | outlineOf runs on Dispatchers.Default; no new main-thread I/O. One data race found (IMPORTANT, OutlineViewModel.kt:44) |
| Tests | Unit coverage good for the view model, tree builder, and row flattening; extraction path uncovered by CI (MINOR) |
| A11y | contentDescription present on rows and the chevron; touch target 22.dp (IMPORTANT). Font scale 1.0/2.0 not verified by me or stated in the PR |
| Build | Build Universal APK green at 13e960cd, so it compiles and spotlessCheck passes |
| Architecture | UDF state/event/effect split, Koin single + viewModel, no new deps, strings in resources, ARCHITECTURE.md updated in the same PR |
No verdict is submitted with this comment; see the follow-up.

Requesting changes on the two IMPORTANT findings, both posted inline.
OutlineViewModel.kt:44--collapsedPathsandcollapsedForPathare mutated from the main thread and read fromDispatchers.Defaultwith no synchronization. Move the collapsed set into aMutableStateFlow<Set<String>>andcombineit into the emitted state.OutlinePanel.kt:194-- the expand/collapse chevron is a 22.dp target inside a row-wide navigate click, so a near-miss moves the caret and closes the drawer. Wrap it in anIconButton, or give it a 48.dp box with the icon centered.
The four MINORs and two NITPICKs do not block. Two are worth doing before merge though: split the whole-file Spotless reindent of EditorSidebarActions.kt out of 281d35eda5 into its own style: commit, and fill in the PR description with the ADFA-2448 link plus the font-scale 1.0/2.0 check CLAUDE.md asks for.
Design and unit-test work are solid otherwise, and seven of the eight findings from the previous round check out as genuinely fixed at head.

Follow-up round: 3 more IMPORTANT, 2 MINOR, 1 NITPICK
A second pass went deeper into the tree-sitter grammars and the editor's event plumbing than my first one did, and turned up three confirmed correctness bugs I had missed. Posting them here rather than amending the earlier review. Changes were already requested; these strengthen that, they do not change the verdict.
Verified independently before posting -- the grammar claims against the node-name tables in the shipped libtree-sitter-kotlin.so and libtree-sitter-java.so, the event claims by reading CodeEditorView.close, IDEEditor.notifyClose/release, and EditorEventDispatcher.
The two highest-value ones are worth restating: private int a, b; silently loses b, and every local val in a Kotlin function shows up in the outline as a property. Both are in the feature's core extraction path, and both are invisible to the current tests.
Leads I checked and rejected, so they don't come back
MutableSharedFlow()replaying stale navigation. The claim was that the zero-buffer, zero-replay flow makesemitsuspend with no collector and then deliver a staleNavigateToon the next START. That inverts the actual contract: with no subscribers andreplay = 0,emitreturns immediately and the value is dropped. So a tap that lands after the fragment stops is discarded, which is the behaviour you want for a navigation effect. No defect.- Passing the live
ContenttooutlineOfto avoid the main-threadtoString().seedFromCurrentEditordoes copy the whole document on the main thread, but the suggested fix is worse than the bug:Contentis mutable and the editor keeps writing to it, so handing it toDispatchers.Defaulttrades a copy for a concurrent-mutation race. The copy is the snapshot.IDEEditoralready does the sametext.toString()on the main thread for everyDocumentChangeEvent(IDEEditor.kt:1292), so this adds one per tab switch to an existing per-keystroke cost. Not worth a change. - Java

One non-blocking note, no comment attached
Built-in rail items go 6 to 7, so SidebarSlotManager.getAvailableSlotsForPlugins() drops from 6 to 5. registerPluginSidebarActions only gates on sideMenuItems.size > declaredSlots, never on canAddPluginItems, so a plugin that reserved 6 slots while the count was still 6 would register all 6 and push the rail to 13 against MAX_NAVIGATION_RAIL_ITEMS = 12. The missing check is pre-existing code this PR only reindented, and it needs a plugin declaring 6+ sidebar items to bite, so nothing to fix here -- but the headroom change is worth a line for plugin authors.
…line Review follow-ups from CodeRabbit on #1804: - OutlineFragment ignores DocumentChangeEvents for files other than the active editor's, so an edit to a background tab no longer swaps the outline away from the file navigateTo targets. The event always carries the new text (IDEEditor posts it), and the active editor's buffer is the fallback, so the main-thread FileManager disk read is gone. - Snapshots are keyed by normalized absolute path instead of basename, so two Main.kt files in different modules no longer share collapse state. - The snapshot collector catches non-cancellation failures around the whole computation (supports() included), so one bad file cannot stop later refreshes. - kt/outline.scm lists a class_parameter as a property only when it is declared val or var; class Repo(name: String) no longer shows "name". The instrumentation fixture gains a plain parameter that must not appear. - Asset readers for outline.scm are closed after reading (provider and query test). Not changed: the android.util.Log calls in EditorSidebarActions predate this branch and are outside its scope.
…-file tracking Review follow-ups from itsaky-adfa on #1804. Extraction: - Java: @symbol.field now sits on each variable_declarator, so `private int x, y;` lists both; dedup keys on the @name node instead of the symbol node. - Kotlin: property_declaration is anchored to class_body, enum_class_body and source_file, so locals inside functions no longer show as properties. `interface` and `enum class` get INTERFACE/ENUM instead of CLASS; when two patterns capture the same name the earlier pattern wins, so the specific patterns are listed first. - outlineOf runs on Dispatchers.Default inside the provider, so the guarantee no longer depends on the caller. View model: collapse state lives in a StateFlow combined into uiState, so the main-thread toggle and the compute thread never share a plain field. Fragment: DocumentCloseEvent is dropped before it reaches EventBus, so closing the last file left a stale outline. The panel now follows EditorViewModel's current-file LiveData (fires on open, tab switch and last-close) and onDocumentOpened has the same active-file guard as onDocumentChanged. Panel: the expand/collapse chevron is a 48.dp IconButton; name and detail sit in a column so a long name cannot squeeze the signature to zero width. Rows: every path segment carries its sibling index, so a symbol literally named `bind#2` cannot collide with a disambiguated sibling. CI: the nightly instrumentation job assembles and runs the editor module's test APK on Firebase Test Lab. Comments on the two androidTest build workarounds name the failure each avoids (duplicate kotlin.reflect.full classes from kt-android.jar; Sentry auto-init crashing the test process).

Round 3 review of ADFA-2448
Re-review at 0208cfcbf. The governing documents are REVIEW.md (the 60-second checklist, the evidence ledger, sections 3, 5, 8, 9, 13) and CLAUDE.md. Neither states an approve/request-changes rule for a reviewer, so the severity scale below is this review's own; CLAUDE.md's Jira rule -- "no outstanding critical, high, or medium findings -> QA" -- is what ties it to the ticket.
The round-2 work landed well. Fourteen of the fifteen findings are genuinely fixed, and I checked each by reading the code at head rather than by trusting the reply. The new findings cluster in the tree-sitter query and extraction layer, which round 2 barely touched.
Round 2 re-check
| Finding | State at 0208cfcbf |
|---|---|
collapsedPaths mutated from two threads |
Fixed. collapsed is a MutableStateFlow<Collapsed> combined into uiState; toggles go through update {}. One plain read-modify-write survives in compute, filed as a NITPICK. |
| 22.dp chevron inside a row-wide click | Fixed. IconButton at TOGGLE_TARGET = 48.dp, leaf rows get a matching Spacer, row is CenterVertically. |
outlineOf runs on the caller's dispatcher |
Fixed. The body is wrapped in withContext(Dispatchers.Default). It turns out that wrapper has no cancellation checkpoint, filed separately. |
No workflow runs editor's androidTest |
Partly fixed. The workflow does assemble and invoke it, but only when the Kotlin and Groovy runs both pass -- see the IMPORTANT on instrumentation-test.yml:146. I have reopened that thread. |
TooltipTag.OUTLINE_SIDEBAR has no DB row |
Open, and I accept the deferral. I read ToolTipManager.showTooltip: a missing row falls through to a documentation-fallback popup, so the long-press is not met with silence. Documented in the ticket and under Known gaps. |
| Spotless reindent mixed into a behavioral commit | Fixed. 7695fd37d style: spotless reformat EditorSidebarActions, no functional change precedes 1f8fa628d, which touches 4 lines of the file. |
#<n> disambiguator collision |
Fixed. Every path segment is name#siblingIndex; OutlineRowsTest pins the deep-duplicate case. |
| Undocumented build workarounds | Fixed. Both carry a why. The kotlin-reflect exclude has a side effect worth a line, filed as a MINOR. |
| Java multi-declarator fields drop names | Fixed. java/outline.scm:27 anchors @symbol.field on each variable_declarator and the dedup key is the @name span; the fixture gained private int x, y; and asserts both. |
Kotlin query matches local val/var |
Fixed for properties, not for functions. The three property patterns are body-anchored; function_declaration was left bare. See the IMPORTANT on kt/outline.scm:23. |
DocumentCloseEvent handler never runs |
Fixed. The fragment observes EditorViewModel.currentFile; removeFile nulls mCurrentFile when the list empties, so the last close reaches onNoEditor(). |
onDocumentOpened has no active-file guard |
Fixed. Same normalized(...) guard as onDocumentChanged. |
Name Text carries no weight |
Fixed. Name and detail are a Column with weight(1f); the detail ellipsizes under the name. |
| Kotlin interfaces/enums get the class badge | Fixed. The interface and enum_class_body patterns precede the class pattern and win on pattern index. That mechanism is fragile, filed as a MINOR. |
| CodeRabbit: reset collapse before the unsupported return | Not a defect. Returning to a file after an unsupported one keeps that file's own collapse state, which is the behaviour you want. Correctly resolved. |
CodeRabbit: android.util.Log in EditorSidebarActions (open) |
Pre-existing. Those three calls are on origin/stage at lines 266/278/286; this PR only reindented them. Out of scope. |
Claims in the description, checked
Every number holds. 12 + 5 + 7 unit tests and 7 + 3 instrumented tests match the files; the rail arithmetic is right (MAX_NAVIGATION_RAIL_ITEMS = 12, built-ins now 7, so 5 plugin slots); the Spotless commit is standalone; ARCHITECTURE.md gained its line. Two I checked that you did not report: the section 13 plugin impact -- no in-tree plugin manifest declares sidebarItems, and PluginManager fails a slot-exceeding plugin with Result.failure(SidebarSlotExceededException) before loading its code, so nothing in-tree regresses -- and #match? @_a "^id$", which does match android:id because this grammar splits ns_prefix from attr_name.
One claim needs narrowing: "the nightly now assembles and runs the editor test APK too" is true only on a night where nothing else fails.
Not evidenced
REVIEW.md's ledger asks for three things this description does not carry: a LeakCanary result for the touched flows (section 2), a StrictMode run (section 3), and JaCoCo line and branch numbers for the new non-UI code (section 5 -- "prove it, don't assert it"; test counts are not coverage). The suites look substantive, so this is a gap in the evidence rather than a suspicion about the code, but it is worth filling before QA.
I did not execute either suite. The re-check above and every finding below is from reading the code at head.
This round
3 IMPORTANT, 7 MINOR, 3 NITPICK, all inline, all confirmed against the diff. Three candidates did not survive verification and are not posted: nesting an anonymous class's members under the field that initialises it is correct structural behaviour, not a defect; the row semantics are fine because Modifier.clickable already sets shouldMergeDescendantSemantics, so the row is one merged focus stop and its contentDescription takes precedence over the merged child text; and the binding-after-destroy race is not reachable, because getEditorAtIndex uses _binding?. and navigateTo's direct binding access sits inside repeatOnLifecycle(STARTED).

Requesting changes on three IMPORTANT findings from the round-3 review; the MINORs and NITPICKs there do not block.
OutlineFragment.kt:80-- gate the snapshot pipeline on the drawer being open, so the outline stops re-parsing the whole file on every typing pause for an offscreen panel.kt/outline.scm:23-- anchorfunction_declarationtoclass_body/enum_class_body/source_filelike the property patterns, and add a localfunto thekotlinSourcefixture so the case is pinned.instrumentation-test.yml:146-- make the editor Test Lab run reachable on a red night (|| trueon eachgcloudcall, or a step per suite withif: always()), and narrow the description's claim that the nightly runs the editor APK.
Also worth doing before QA, though not blocking: the REVIEW.md ledger items the description does not carry -- LeakCanary for the touched flows, a StrictMode run, and JaCoCo line and branch numbers for the new non-UI code.
Round 2 was solid work -- 14 of 15 findings genuinely fixed. Happy to re-review as soon as these three land.
…un the editor suite on red nights Round-3 review follow-ups from itsaky-adfa. Blocking three: - OutlineFragment holds the DrawerLayout it registers on and gates every snapshot on the drawer being open, so a closed panel stops re-parsing the file on each typing pause. A DrawerListener re-seeds on open, which is what keeps a file switch made while the drawer was closed from going unnoticed. - kt/outline.scm anchors function_declaration to class_body, enum_class_body and source_file like the property patterns, so a local fun no longer shows up in an outline that already drops local vals. The instrumented fixture gained `fun helper()` inside add(). - instrumentation-test.yml captures each suite's exit code with `|| SUITE_EXIT_CODE=$?` instead of letting bash -e abort the step, so the editor suite runs even when the Kotlin or Groovy one fails, and a trailing check re-fails the step if any suite failed. Plain `|| true` would have turned a failing nightly green. Also: - centerPositionInView re-checks isValidPosition inside onDrawerClosed; the earlier check was several hundred milliseconds stale by then. - A named companion keeps its name: one pattern with an optional capture, `(companion_object (type_identifier)? @name)`, covers named and anonymous companions without two patterns fighting over the same node. - Dedup compares patternIndex first and uses detail only within one pattern. That required reordering xml/outline.scm so its two detail-bearing patterns precede the plain ones; otherwise the id detail on an XML element would have been dropped by the new precedence. - OutlineSymbolKind.fromCaptureSuffix owns the capture-to-kind mapping, and a new JVM test (OutlineQueryCapturesTest) asserts every @symbol.* capture in all three .scm files resolves to a kind, so a typo fails the gating suite rather than showing an empty outline. - The kotlin-reflect exclude records that MockK is unusable in editor androidTest as a consequence. - extract() takes the coroutine context and calls ensureActive() per match, so a superseded parse stops at the next match instead of running to completion. - OutlineFragment.onDestroyView calls onNoEditor(), releasing the document copy the activity-scoped view model would otherwise hold after the panel is gone. - Content no longer carries an always-empty collapsedPaths; the panel collects collapsedPaths from its own StateFlow, which also removes the combine. - compute() resets the collapse set with a single getAndUpdate, so both writers now go through one atomic operation. - OutlineTreeBuilder pops until the stack top strictly contains the candidate, so a partial overlap or an identical range makes a sibling, not a child.

The Column introduced for the round-3 review put every signature on its own line, so `onDestroy` showed `()` underneath it with most of the row empty. FlowRow keeps name and detail on one line while there is room and wraps the detail only when there is not, which still prevents a long name from squeezing the signature to zero width.

Round 3 addressed at 01a4300, plus 44bbe8d for a UI regression the round-3 layout fix introduced. Per-thread replies are inline. The three blocking ones: the snapshot pipeline is gated on the drawer being open with a re-seed on open (verified on device: file switched while closed, panel showed the new file on reopen); Two of your suggestions needed a different shape than proposed, both caught on device:
Evidence ledger, now in the description: scoped JaCoCo for the new non-UI code gives line 32/32 and branch 14/14 for the editor extraction, line 46/49 and branch 20/23 for the app state and rows; One thing worth a separate ticket, found while measuring coverage: Also, thanks for the note that the tooltip miss falls through to a documentation popup rather than silence - I had it recorded as an empty popup and have stopped claiming that. |
