Autotext Tester

Adapted from AutoTextTestDlg.cpp/.h and IDD_AUTOTEXTTESTDLG at the pinned TortoiseGit source revision recorded in PORTING.md. GPL-2.0-or-later.

The native fixed-size window retains the source order: editable file content, regex, explicit default Scan button, read-only auto words, parse timing and Exit. It supports light/dark system appearance and plain-text private clipboard menus with the application's icon preference. Content is limited to 200 × 1024 UTF-16 units. Source CString conversion stops content at its first NUL for scanning.

The packaged C++ helper compiles case-insensitive ECMAScript expressions. Every nonempty capture group is collected, deduplicated and sorted by UTF-16 order; whole matches are not implicitly words. Empty input clears result/timing without launching the helper. Invalid expressions replace results with the source error prefix. The helper contains pathological expressions with bounded execution. Elapsed timing includes helper startup/IPC, unlike the source in-process clock.

Scan runs off the main actor. Inputs are disabled during scanning. Exit cancels owned helper work and fences late results; Quit waits for active matching to settle. The utility never writes completion definitions or repository settings. The standalone File-menu entry adapts AutoTextTestCommand.h (autotexttest), which requires neither a repository nor Git. An additional button in Settings → Dialogs 2 → Commit opens one page-owned tester. Leaving that page closes it. The settings shortcut is a macOS addition. Legacy Windows command-line spelling remains pending.

Remaining acceptance: physical keyboard/VoiceOver review, exact font/spacing comparison against a running Windows dialog, signed sandbox execution and the complete upstream autocompletion configuration/editing workflow. This dialog is partial, not certified complete.

Actual Aqua/Dark Aqua compositor captures were compared with the pinned resource control order. They exposed an NSHostingController fitting-width collapse, missed by data/control tests. Window minimum/maximum constraints alone did not prevent that programmatic resize. The fixed SwiftUI host frame and explicit content size now retain the intended 660 × 640 point dialog. The focused receiver checks actual content bounds, and the capture case rejects collapsed PNG dimensions. Reviewed images show both editors, full labels, Scan, results, timing and Exit. See the utility capture record; physical/signed and full visual certification remain open.

Explicit utility ownership — October 18, 2026

The no-Git autotexttest command now opens an independently owned native tester. Repeated entry focuses its existing window without replacing content, regex or a pending scan, including when the window has not yet been made visible. Closed controllers notify their owner and a later command creates a fresh tester. Command and Settings-child owners remain separate. Both supply their own preference store. Retirement still cancels the packaged matcher and fences late publication while its active counter remains until real return.

Service command evidence records checks and remaining physical/native/signed acceptance. The ECMAScript helper and source capture/limit/timing semantics are unchanged.
