+
+This accessibility library is a fork of the [chromium](https://www.chromium.org) accessibility code at commit
+[4579d5538f06c5ef615a15bc67ebb9ac0523a973](https://chromium.googlesource.com/chromium/src/+/4579d5538f06c5ef615a15bc67ebb9ac0523a973).
+
+For the main ax code, the following parts were not imported:
+`fuzz_corpus`, `extensions` and `DEPS` files.
+
+`ax/`: https://source.chromium.org/chromium/chromium/src/+/master:ui/accessibility/
+`ax_build/`: https://source.chromium.org/chromium/chromium/src/+/master:build/
+`base/`: https://source.chromium.org/chromium/chromium/src/+/master:base/
+`gfx/`: https://source.chromium.org/chromium/chromium/src/+/master:ui/gfx/
+
+Update to this Library
+==============
+Bug fixes to the forked files in the four directories should proceed as usual.
+New features or changes that change the behaviors of these classes are discouraged.
+
+If you do need to make such change, please log the change at the end of this file.

 # Web Locale Keymap
 
-# Usage
+This package maps Web's KeyboardEvent to Flutter's logical keys. It only
+includes "locale sensitive" keys, which are all the letters, regular digits, and
+symbols. It works for all layouts shown in [Microsoft/VSCode](https://github.com/microsoft/vscode) repo.
 
-https://pub.dev/packages/web_locale_keymap
+The mapping data and test cases are generated by `gen_web_locale_keymap` package.
+Do not edit them manually.
 
-[![pub package](https://img.shields.io/pub/v/web_locale_keymap.svg)](https://pub.dev/packages/web_locale_keymap)
+# Usage
 
-```yaml
-dependencies:
-  web_locale_keymap: ^<latest-version>
+1. Ensure that the key is a locale key.
+2. Get the logical key from `getLogicalKey()`.
+3. If the return value is null, then the key can not be mapped as a character
+either. Mint the logical key value.
+
+```dart
+import 'package:web_locale_keymap/web_locale_keymap.dart' as locale_keymap;
+
+final locale_keymap.LocaleKeymap mapping =
+    locale_keymap.LocaleKeymap.win(); // Or .darwin() or .linux()
+
+/* ... */
+
+int getLogicalKey(html.KeyboardEvent event) {
+  int? result = _convertToDeadKey(event)
+             ?? _convertToUnprintableKey(event)
+             ?? _convertToNumpadKey(event);

-## Web Keyboard Layouts Generator
+# Web Locale Keymap Generator
+
+This script generates mapping data for `web_locale_keymap`.
+
+## Usage
+
+1. `cd` to this folder, run `dart pub get`.
+2. [Create a Github access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token), then store it to environment variable `$GITHUB_TOKEN`. This token is only for quota controlling and does not need any scopes.
+```
+# ~/.zshrc
+export GITHUB_TOKEN=<YOUR_TOKEN>
+```
+3. Run
+```
+dart --enable-asserts bin/gen_web_locale_keymap.dart
+```
+
+### Help
+For help on CLI,
+```
+dart --enable-asserts bin/gen_web_locale_keymap.dart -h
+```
+
+## Explanation
+
+To derive a key map that allows international layout to properly trigger
+shortcuts, we can't [simply map logical keys from the current
+event](https://github.com/flutter/flutter/issues/100456). Instead, we need to
+analyze the entire current layout and plan ahead. This algorithm,
+which we call the benchmark planner, goes as follows:
+
+> Analyze every key of the current layout,
+> 1. If a key can produce an alnum under some modifier, then this key is mapped to this alnum.
+> 2. After the previous step, if some alnum is not mapped, they're mapped to their corresponding key on the US keyboard.
+> 3. The remaining keys are mapped to the unicode plane according to their produced character.
+
+However, we can't simply apply this algorithm to Web: unlike other desktop
+platforms, Web DOM API does not tell which keyboard layout the user is on, or
+how the current layout maps keys (there is a KeyboardLayout API that is
+supported only by Chrome, and explicitly refused by all other browsers). So we
+have to invent a "blind" algorithm that applies to any layout, while keeping the
+same result.
+
+Luckily, we're able to fetch a list of "all keyboard layouts" from
+`Microsoft/VSCode` repo, and we analyzed all layouts beforehand, and managed to
+combine the result into a huge `code -> key -> result` map. You would imagine it
+being impossible, since different layouts might use the same `(code, key)` pair
+for different characters, but in fact such conflicts are surprisingly few, and
+all the conflicts are mapped to letters. For example, `es-linux` maps
+`('KeyY', '←')` to `y`, while `de-linux` maps `('KeyY', '←')` to `z`.
+
+We can't distinguished these conflicts only by the `(code, key)` pair, but we
+can use other information: `keyCode`. Now, keyCode is a deprecated property, but
+we really don't see it being removed any time foreseeable. Also, although
+keyCode is infamous for being platform-dependent, for letter keys it is always
+equal to the letter character. Therefore such conflicting cases are all mapped
+to a special value, 0x01, indicating "use keyCode".
+
+Moreover, to reduce the size of the map, we noticed there are certain patterns
+that can be easily represented by some if statements. These patterns are
+extracted as the so-called "heuristic mapper". This reduces the map from over
+1600 entries to ~450 entries.

 Moreover, to reduce the size of the map, we noticed there are certain patterns

 extracted as the so-called "heuristic mapper". This reduces the map from over
 1600 entries to ~450 entries.
