+# Layout Fixer Changelog
+
+## [Initial Version] - {PR_MERGE_DATE}
+
+- Fix text typed with the wrong keyboard layout between Arabic and English,
+  in either direction, with the direction detected automatically
+- Converts the selection, or the whole focused text field when nothing is
+  selected
+- Supports both the macOS "Arabic" and Windows "Arabic (101)" layouts, which
+  differ across the entire bottom row; defaults to whichever matches the
+  computer you're on
+- Runs on both macOS and Windows

+# Layout Fixer
+
+You meant to type `مرحبا`, but the keyboard was still on English, so the screen
+says `lnpfh`. Run the command and it becomes `مرحبا`. It works the other way
+too — `اثممخ` typed on a stuck Arabic layout becomes `hello`.
+
+No retyping, no pasting into a website.
+
+## Using it
+
+Bind **Fix Keyboard Layout** to a hotkey (Raycast → Extensions → Layout Fixer),
+then hit it whenever you catch yourself typing in the wrong layout.
+
+| Situation | What happens |
+| --- | --- |
+| Text is selected | The selection is converted in place |
+| Nothing selected, cursor in a text field | The whole field is selected and converted |
+| Neither | A HUD tells you there's nothing to fix, and nothing is touched |
+
+The direction is detected automatically by counting characters — mostly-Latin
+text converts to Arabic, mostly-Arabic text converts to Latin. You never pick a
+direction, and running the command twice gets you back where you started.
+
+## Which Arabic layout?
+
+**The Mac and Windows Arabic keyboards are not the same keyboard.** They agree
+on the top two letter rows and disagree almost everywhere else — most visibly
+across the bottom row:
+
+| key | macOS "Arabic" | Windows "Arabic (101)" |
+| --- | --- | --- |
+| `n` | ر | ى |
+| `v` | د | ر |
+| `b` | ز | لا |
+| `m` | و | ة |
+| `z` `x` `c` | ظ ط ذ | ئ ء ؤ |
+| `]` | ة | د |
+| digits | ٠١٢٣ | 0123 |
+
+So `مرحبا` is `lnpfh` on a Mac and `lvpfh` on Windows. Getting this wrong
+produces plausible-looking nonsense rather than an obvious failure, which is
+why it's a preference.
+
+**Arabic Keyboard Layout** defaults to *Match This Computer*, which follows the
+OS you're running on. Set it explicitly if that's not what you type on — in
+particular, pick **Windows** if you're on a Mac but use the *"Arabic - PC"*
+input source rather than the plain *"Arabic"* one.
+
+Both tables cover every key: letters, shifted diacritics (َ ً ُ ٌ ِ ٍ ْ ّ),
+Arabic punctuation (، ؛ ؟ ـ ٫ ٬ ٪), the lam-alef ligatures on Windows
+(لا لأ لإ لآ), and the mirrored brackets and Arabic-Indic digits on macOS.
+
+The macOS table wasn't transcribed by hand — it was extracted from macOS's own
+Text Input Sources via `UCKeyTranslate` and matches the system layout on all 94
+keys. The Windows table cross-checks against macOS's "Arabic - PC" layout on
+all 36 letters.
+
+## How it works
+
+Raycast can read the frontmost app's *selection*, but there's no API for
+reading a focused text field outright. So when nothing is selected, the
+extension sends a Select All (⌘A on macOS, Ctrl+A on Windows) and reads that
+instead, then pastes the fixed text back over it.
+
+Two consequences worth knowing:
+
+- **macOS needs Accessibility permission** for Raycast, since the Select All is
+  a synthetic keystroke. Raycast will prompt the first time; if the whole-field
+  path silently does nothing, check System Settings → Privacy & Security →
+  Accessibility.
+- **If focus isn't in a text field**, Select All grabs whatever else is
+  selectable — the entire page in a browser, every file in Finder. The
+  extension refuses anything over 5,000 characters and collapses the selection
+  it made, rather than rewriting your window. Select the text explicitly if you
+  genuinely need to fix something that long.
+
+Replacement goes through `Clipboard.paste`. Raycast restores the previous
+clipboard afterwards, so whatever you had copied survives a run — verified by
+holding a sentinel string across both the selection and whole-field paths.
+
+The conversion itself is a lookup table built on first use — the only real cost
+in a run is the process spawn for the Select All, and that's skipped entirely
+when you already have text selected.
+
+## Known ambiguities
+
+Two physical keys sometimes produce the same Arabic character, and the text
+doesn't record which one you pressed. Where that happens, Layout Fixer picks
+the reading that's commoner in English:
+
+- **Windows:** `لا` is either the single `b` key or `g` then `h`. It picks `b`,
+  so a word containing `gh` won't survive a there-and-back round trip.
+- **macOS:** `ـ` (tatweel) is either `` ` `` or `_`. It picks `_`.
+
+Neither affects the direction you actually care about — Latin → Arabic is
+unambiguous both ways.
+
+## Development
+
+```bash
+npm install
+npm run dev
+```
+
+`npm run lint` runs ESLint and Prettier; `npm run build` produces a
+distribution build. The layout tables in [`src/layouts.ts`](src/layouts.ts) are
+marked `// prettier-ignore` so they stay laid out like a keyboard.
+
+The icon is generated rather than drawn by hand; the generator script lives in
+the standalone repo linked below.
+
+## Layout
+
+```
+src/
+  fix-layout.ts   the command: read selection → fix → paste
+  keystrokes.ts   cross-platform Select All / collapse selection
+  layouts.ts      both layout tables + convert/detect
+```
+
+Developed at [ramysami/layout-fixer-raycast](https://github.com/ramysami/layout-fixer-raycast),
+which also carries the icon generator. There's a
+[Chrome extension version](https://github.com/ramysami/Layout-fixer) that does
+the same thing in the browser.
