Release Notes - ADFA-2838: Add Jetpack Compose Preview Documentation Tooltip

• Context-aware tooltips: Added a distinct Compose preview tooltip key editor.compose.preview (TooltipTag.EDITOR_TOOLBAR_PREVIEW_COMPOSE).
• Compose detection: Implemented moduleUsesCompose() helpers to detect the presence of the Compose runtime dependency:
  • moduleUsesCompose(): scans workspace Android modules for androidx.compose.runtime:runtime.
  • moduleUsesCompose(file): resolves the module for a file and checks that module specifically.
• Safer editor/data access: prepare() rewritten to use data.getEditor(), data.getActivity() guards, and viewModel initialization checks instead of requireEditor(); postExec() updated to safely retrieve editor/file before invoking editor handlers.
• Preview type handling: Preview action now distinguishes XML layout previews and Compose previews (COMPOSE), and sets visibility/enabled flags appropriately; supports pre-setting COMPOSE when module-level Compose is present even without an open file.
• XML/Kotlin handling: XML layout detection now uses extractPathData(file).type to identify layout files; Kotlin files (.kt) are treated as Compose candidates only if moduleUsesCompose(file) is true.
• Internal helpers added and private logic refactored to avoid throwing on missing editors/files; no public API signatures changed.

⚠️ Risks and Best-Practices Concerns

• Performance: moduleUsesCompose() may be invoked frequently from prepare() (on editor interactions) and traverses workspace modules/dependencies each time. Recommendation: cache results and invalidate on workspace/module changes.
• Module vs. project scope: The implementation includes both module-aware and project-scan helpers, but some code paths pre-check project modules without module context. In multi-module repositories, ensure the check used is the module-specific one to avoid showing Compose preview for files in non-Compose modules.
• State staleness: previewType is computed in prepare() and used in postExec(); without synchronization or caching, workspace/module changes between calls could produce stale state.
• Error handling: extractPathData() and other file-inspection failures silently set invisibility; consider explicit logging or user-visible diagnostics to aid debugging.
• Complexity and testability: prepare() contains multiple guarded paths and flags (visibility/enabled); consider refactoring to smaller, testable functions or a single sealed-state model.
• Testing gaps: add tests for mixed Compose/non-Compose multi-module projects, rapid file switching, null workspace/editor scenarios, and validation that editor handler invocations receive valid data.

Lines changed (approximate):

• PreviewLayoutAction.kt: +56 / -51
• TooltipTag.kt: +1 / -0

Walkthrough

Adds Compose preview support to PreviewLayoutAction, detects Compose dependency via IProjectManager, refactors prepare()/postExec() to use safe editor/file retrieval and guarded visibility/enabled states, and introduces a new tooltip constant for Compose previews.

Changes

Cohort / File(s)	Summary
Preview Action Enhancement app/src/main/java/com/itsaky/androidide/actions/etc/PreviewLayoutAction.kt	Rewrote prepare() and postExec() to use safe data.getEditor() and file derivation, added moduleUsesCompose() helpers (workspace- and file-based) to detect androidx.compose.runtime, adjusted visibility/enabled logic for XML (.xml) and Kotlin/Compose (.kt) cases, and switched tooltip tag selection based on preview type.
Tooltip Constants idetooltips/src/main/java/com/itsaky/androidide/idetooltips/TooltipTag.kt	Added EDITOR_TOOLBAR_PREVIEW_COMPOSE = "editor.compose.preview" constant for Compose preview tooltips.

🐰 I sniffed the modules, found Compose light,
Switched tooltips quick and kept things tight.
XML hops in, Kotlin joins the show,
A tiny preview garden begins to grow! 🌱✨

In `@app/src/main/java/com/itsaky/androidide/actions/etc/PreviewLayoutAction.kt`:
- Around line 85-90: The catch block around extractPathData in
PreviewLayoutAction currently swallows all Throwables and just calls
markInvisible(); update it to log the exception (at debug or warn level) with
context before calling markInvisible() and returning so failures are
diagnosable; locate the try/catch around extractPathData(...) in
PreviewLayoutAction (the catch handling Throwable err) and add a process or
logger call that includes err and a short message identifying the
file/operation.

109-117: Fallback shows Compose tooltip even for XML files during initialization.

When viewModel.isInitializing is true andfile is non-null (e.g., an .xml file), this branch still sets previewType = COMPOSE if the project uses Compose. The button is disabled so it's not clickable, but the tooltip will briefly show the Compose preview hint instead of the layout preview one until initialization completes and prepare() is re-invoked.

If that transient tooltip mismatch is acceptable, feel free to ignore.
