Pure Codename One rich text and code editors (remove BrowserComponent) by shai-almog · Pull Request #5378 · codenameone/CodenameOne

shai-almog · 2026-07-14T00:44:29Z

Summary

Replaces the BrowserComponent-backed RichTextArea (WYSIWYG) and CodeEditor with a 100% pure Codename One text engine (com.codename1.ui.editor) that renders the document itself with Graphics/Font and binds directly to the platform text input source (soft keyboard, hardware/Bluetooth keyboard, IME). The public API of both components is preserved, so this is a drop-in replacement.

What's included

Low-level text input source API (TextInputClient/TextInputState/TextInputConfig + an impl SPI on CodenameOneImplementation), bound per port:
- Android: a custom InputConnection (CN1TextInputConnection) on the surface views (no shadow EditText).
- iOS: a first-responder UITextInput view (CN1TextInputView) - soft + hardware/Bluetooth keyboard + IME.
- JavaSE: InputMethodListener + key listeners.
Editor engine: single-buffer document model, incremental stateful syntax tokenizer, coalescing undo, styled rich runs + inline images, HTML import/export, code completion popup and diagnostics squiggles.
Bidirectional (RTL) text: a compact Unicode Bidi Algorithm core (BidiUtil) wired into caret geometry, hit-testing, selection and rendering for the base, code and rich views (mixed LTR/RTL, numbers-in-RTL, etc.).
IME / CJK marked-text composition with an inline composing underline.
Native-feel touch selection: cross-platform CN1-drawn selection handles + a magnifier loupe + a Copy/Cut/Paste/Select All toolbar, plus the native iOS system magnifier / handles / edit menu via UITextInteraction (verified on device).
Removes the HTML/BrowserComponent backend: deletes CodeEditorHtml and the createEditorHtml() paths, and the now-dead CodeEditor -> CodeMirror bundling in the Maven plugin IPhoneBuilder/AndroidGradleBuilder and GLViewController.h. Backend-switch methods (setDefaultBackend, getInternalBrowser, CodeEditor.setEngineURL, ...) are kept as deprecated no-ops for source compatibility.

Testing

66 new core unit tests (com.codename1.ui.editor.*): bidi algorithm + geometry integration, document model, CJK composing, pure-backend selection/round-trip.
Full core-unittests suite green: 3867 tests, 0 failures.
iOS native selection (magnifier + handles + edit menu) verified on the iPhone 16 simulator.
New PureEditorScreenshotTest (RTL-in-code + mixed rich text) added to the hellocodenameone suite; its PureEditors golden adopts from the first CI run.

Notes

The dead CodeMirror bundling in the separate BuildDaemon repo is removed in a companion PR (codenameone/BuildDaemon drop-codemirror-editor).
While the editor is focused on iOS the native text interaction owns drags (no drag-to-scroll inside the editor; caret nav and form scroll still work) - a deliberate tradeoff for the native selection UI.

The core-unittests SpotBugs check (threshold Low, fail on any) flagged the new editor code. Fix the real findings and suppress a style-only one: - BidiUtil: use a bitwise odd-check (IM_BAD_CHECK_FOR_ODD) and drop the unreachable 0x00A0 branch in typeOf (UC_USELESS_CONDITION). - RichPureEditor.loadImage: avoid String.getBytes() default encoding (DM_DEFAULT_ENCODING) by converting the ASCII base64 payload directly, and use >= 0 for the indexOf checks (RV_CHECK_FOR_POSITIVE_INDEXOF). - RichView.setList: remove a dead local store (DLS_DEAD_LOCAL_STORE). - spotbugs-exclude: suppress SIC_INNER_SHOULD_BE_STATIC_ANON for the editor package (its StyleTransform/StylePredicate/BlockOp anonymous impls capture only locals; the refactor is noise). Also add EditorLayoutTest verifying RichTextArea/CodeEditor lay out below the form Toolbar. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

HtmlImporter only handled amp/lt/gt/quot/apos/nbsp and numeric entities, so common named entities such as — rendered as literal text. Add the common typography and symbol entities (mdash, ndash, hellip, curly quotes, copy, reg, trade, times, euro, pound, ...). Covered by HtmlImporterTest. Also add getVerticalScroll() plus EditorFirstLineTest, which confirms the editor shows line 0 at the top after loading content (scroll stays 0), complementing EditorLayoutTest (editors sit below the form Toolbar). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

setText() reset scrollY to 0 and then called scrollCaretVisible(). When the backend flushes the queued setText before the component is laid out (getHeight() is still 0), contentHeight() is negative once padding is subtracted, so the "caret below the viewport" branch fired even for the caret on line 0 and pushed scrollY to roughly one line. The first content line then scrolled under the form title bar on device and in the simulator (headless tests missed it because they set the text after layout). Guard scrollCaretVisible() against an unlaid-out viewport (contentHeight <= 0) and add a laidOut() override that re-clamps scrollY and applies any deferred scroll-to-caret once the real bounds are known. Add a regression test that sets the text before the first layout, reproducing the device ordering. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

@OverRide

The pure editor code tripped several CI gates that only run in the full PR workflow (not the SpotBugs-only local check): - PMD forbidden-rules gate (generate-quality-report.py): resolved 62 findings in the new editor sources - add @OverRide where methods override/implement, convert indexed loops to foreach, split multi-declarations, drop unnecessary fully-qualified names / imports / constructor, make BidiUtil final, remove unused measureLine params, and restructure a break-as-last-in-loop into a helper. Genuine identity comparisons (cached fonts, the ThemePalette singleton) and owned StringBuilder buffers (document buffer, HTML importer) are marked // NOPMD with a reason since changing them would be incorrect. - JavaDoc package-info gate: add package-info.java for com.codename1.ui.editor. - Developer guide quality gate: fix the Vale findings in the RichTextArea / CodeEditor sections (contraction, cliche, adverb) and disable the LanguageTool UPPERCASE_SENTENCE_START rule, which false-positives on deliberately lowercase asciidoc ordered-list continuation items (matching the existing ENGLISH_WORD_REPEAT_BEGINNING_RULE exception). No behavior change. Verified: core-unittests verify (3876 tests pass, SpotBugs 0 bugs, PMD gate clean), Vale 0/0/0 on the edited guide, package-info check passes.

The RichTextArea and CodeEditor screenshot tests pre-date this PR and their goldens were captured against the old BrowserComponent editor; the new PureEditors test had none. Re-capture all three from the CI run of the fixed commit (first line no longer clipped, HTML entities and RTL/bidi rendering correctly) across every capturing platform (android, javascript, windows, mac-native, linux x64/arm, iOS gl/metal/tv/watch). Refresh the tolerance comments to describe the pure text render instead of the removed web widget. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

PureEditorScreenshotTest was registered before the graphics screenshot tests. Creating a pure editor warms Android's native-font path, so the default-font text drawn by graphics-draw-string, graphics-draw-string-decorated and graphics-inscribed-triangle-grid rendered differently than their goldens (which were captured with the editor tests running after the graphics suite, like RichTextArea/CodeEditor already do). Android-only, deterministic since the first branch commit; other platforms were unaffected. Move the test into the editor-screenshot cluster so every editor test runs after the graphics tests, restoring the cold-font ordering the graphics goldens capture. No production code change.

Compared 142 screenshots: 142 matched.
Native Windows port (x64 / Intel-AMD): full hellocodenameone screenshot suite rendered offscreen with Direct2D/DirectWrite, plus the real benchmarks (base64 native/CN1/SIMD, image createMask/applyMask/modifyAlpha/PNG/JPEG, SSE2 SIMD kernels). Compared against the in-repo baseline in scripts/windows/screenshots.

Benchmark Results

Detailed Performance Metrics

Metric	Duration
SIMD kernel backend	SSE2 (x64) / NEON (arm64) native kernels
SIMD int-add (64K x300)	java 54ms / native 3ms = 18.0x speedup
SIMD float-mul (64K x300)	java 49ms / native 3ms = 16.3x speedup
SIMD kernel correctness	PASS (native result == scalar reference)
Base64 native bridge	unavailable (CN1 + SIMD + image benchmarks only)
Base64 payload size	8192 bytes
Base64 benchmark iterations	6000
Base64 SIMD byte path	gated to scalar (CPU autovectorizes scalar; explicit SIMD not beneficial here)
Base64 CN1 encode	168.000 ms
Base64 CN1 decode	101.000 ms
Base64 SIMD encode	79.000 ms
Base64 encode ratio (SIMD/CN1)	0.470x (53.0% faster)
