-// Validate Flutter ARB translation catalogs before localization code generation.
-//
-// Usage (from ui/flutter):
-//   dart run ../../.github/workflows/scripts/check_l10n.dart
-//
-// What it checks:
-// - Every ARB file uses the repository's canonical two-space JSON formatting.
-// - Every app_<locale>.arb file declares the matching @@locale value.
-// - Message values are not empty (warning only).
-// - Every locale has the same message keys as app_en.arb (warning only).
-// - Every translation preserves the placeholder variables used by app_en.arb
-//   (warning only).
-//
-// Notes:
-// - This script does not judge translation quality.
-// - It does not generate localization code or fully parse ICU MessageFormat.
-//   `flutter gen-l10n` runs immediately afterwards in CI to validate ICU syntax
-//   and generate app_localizations*.dart.
-// - The script exits with a failure only for malformed JSON, invalid ARB
-//   formatting, or a mismatched @@locale value. Translation completeness is
-//   reported as warnings; generation and analysis remain the compile-time gate.

-// Localize external Google Fonts (fonts.gstatic.com) references in Flutter Web build output.
-//
-// Usage (post-build):
-//   # Run AFTER: flutter build web --no-web-resources-cdn
-//   dart ../../.github/workflows/scripts/flutter_local_font.dart
-//
-// What it does:
-// In main.dart.js:
-//    - Find any referenced resources under: https://fonts.gstatic.com/s/
-//      (including the common pattern where Flutter concatenates the base URL with a relative path)
-//    - Download them into: build/web/assets/gstatic/<path>
-//    - Rewrite "https://fonts.gstatic.com/s/" -> "assets/gstatic/" so runtime loads locally
-//    - Only download font subsets needed by supported locales (parsed from lib/l10n/*.arb)
-//
-// Notes:
-// - This script DOES NOT call `flutter build web`. It only patches the output.
-// - This is a best-effort post-process. Always verify in browser devtools.

 ## Translation
 
-Flutter translations are ARB files in `ui/flutter/lib/l10n`. Use `app_en.arb` as the source template,
+The internationalization files of Gopeed are located in the `ui/flutter/lib/i18n/langs` directory.
-then edit or add `app_<locale>.arb` (for example, `app_de.arb` or `app_zh_TW.arb`). Every locale must
+You only need to add the corresponding language file in this directory.
-contain the same message keys as the English template.
 
-Translate message values only, and do not rename variables inside braces such as `{count}` and `{name}`.
+Please refer to `en_us.dart` for translation.
-Do not translate metadata keys prefixed with `@`. Submit only the ARB source files you changed; do not generate or commit
-`app_localizations*.dart`. The pull-request CI automatically validates the catalogs, generates the
-localization code, and checks its integration.
-
-The following examples show both the ARB definition and the text users see after the app supplies values.
-
-1. Insert a variable into a message
-
-   ARB definition:
-
-   ```json
-   "welcomeUser": "Hola, {name}"
-   ```
-
-   Rendered result: when `name = Ana`, users see “Hola, Ana”. You may reorder the sentence, but keep `{name}`.
-

-   ```json
-   "fileCount": "{count, plural, =0{No hay archivos} =1{1 archivo} other{{count} archivos}}"

-   - `count = 0` → “No hay archivos”
-   - `count = 1` → “1 archivo”
-   - `count = 3` → “3 archivos”
-
-   `=0`, `=1`, and `other` mean zero, one, and every other quantity. Translate only the user-visible text
-   inside each branch.

-
-   ARB definition:
-
-   ```json
-   "taskState": "{state, select, running{En curso} paused{En pausa} other{Desconocido}}"
-   ```
-
-   Rendered results:
-
-   - `state = running` → “En curso”
-   - `state = paused` → “En pausa”
-   - Any other value → “Desconocido”
-
-   `running`, `paused`, and `other` are values supplied by the app. Do not translate them; translate only
-   the display text inside the following braces.

-`app_localizations*.dart` は生成もコミットも不要です。PR の CI が全言語を検証し、国際化コードを生成して
-統合結果を確認します。

-   "welcomeUser": "こんにちは、{name}"
-   ```
-
-   最終表示：`name = 太郎` の場合は「こんにちは、太郎」と表示されます。語順は変更できますが、`{name}` は残します。
-
-2. 数量に応じて表示を切り替える
-
-   ARB 定義：
-
-   ```json
-   "fileCount": "{count, plural, =0{ファイルなし} =1{1 個のファイル} other{{count} 個のファイル}}"
-   ```
-
-   最終表示：

-   - `count = 0` →「ファイルなし」
-   - `count = 1` →「1 個のファイル」
-   - `count = 3` →「3 個のファイル」
-
-   `=0`、`=1`、`other` はそれぞれ 0、1、その他の数量を表します。各分岐の中で画面に表示される文字だけを翻訳します。

+## Development
 
-## 👨‍💻 Development
+This project is divided into two parts, the front end uses `flutter`, the back end uses `Golang`, and the two sides communicate through the `http` protocol. On the unix system, `unix socket` is used, and on the windows system, `tcp` protocol is used.
 
-Gopeed consists of a Flutter front end and a Go back end. They communicate over HTTP, using Unix sockets on Unix-like systems and TCP on Windows.
+> The front code is located in the `ui/flutter` directory.
 
-> The front-end source is located in the `ui/flutter` directory.

-# Batch task creation
-
-`POST /api/v1/tasks/batch` accepts ordinary and grouped batches:
-
-```json
-{
-  "group": true,
-  "groupName": "album",
-  "opts": {"path": "/downloads"},
-  "reqs": [
-    {"rid": "resolved-resource-id", "opts": {"selectFiles": [1]}},
-    {"req": {"url": "https://example.com/cover.jpg"}}
-  ]
-}
-```
-
-Each member accepts `rid` or `req`. A nonempty `rid` takes priority and creates a
-task from the cached resolve result. A member's `opts`, when present, replaces
-batch `opts` as a whole; omitted fields do not inherit individual batch values.
-Members without `opts` use batch `opts`. BT file selections use the indexes from
-the resolve result. Requests without `rid` continue to work.
-
-For groups, batch `opts.path` selects the parent directory. Members inheriting
-batch options, or with an empty path, use the reserved group directory. Explicit
-relative member paths are resolved under that directory; do not prefix them with
-the batch parent path. For example, parent `downloads` and member path `nested`
-place the member in `downloads/<group name>/nested`. Absolute paths under the
-parent directory preserve their relative structure within the group. In ordinary
-batches, an empty member path uses the configured default download directory.
-
-All members are attempted. If at least one task is persisted, the response is
-successful and contains the created task IDs. A task that fails to start after
-being persisted is included; use the existing task controls to retry it.
-Successful tasks are kept when other members fail. If every member fails, the
-API returns an error and removes any newly reserved empty group and directory.
-
-Both ordinary and grouped batches now return an object in `data`:
-
-```json
-{"code": 0, "msg": "", "data": {"taskIds": ["task-1", "task-2"], "parentId": "group-id"}}
-```
-
-Ordinary batches omit `parentId`. **This replaces the former array response for
-ordinary batches.** The outer `code`/`msg`/`data` envelope is unchanged. Clients
-must read `data.taskIds`; there are no per-member results. A successful response
-completes the batch, including partial success, so clients must not automatically
-resubmit missing members.
-
-With `group: true`, the server generates the group ID and reserves its directory.
-Creation does not accept a client group ID or append to an existing group. Group
-metadata remains available through the existing task list and detail responses;
-`parentId` identifies membership for group operations.

-# GitHub mirror execution
-
-This package owns GitHub URL rewriting and execution strategies. It depends only
-on the standard library and does not depend on Downloader, HTTP clients, Git, or
-storage. Downloader persists `Config` at its top-level `githubMirror` field;
-`pkg/base` preserves the existing configuration names through aliases.
-
-## Race: resource reads
-
-```go
-body, err := githubmirror.Race(ctx, cfg.GithubMirror, rawURL,
-    githubmirror.Options[[]byte]{
-        Kind:    githubmirror.Resource,
-        Timeout: 30 * time.Second,
-    },
-    func(ctx context.Context, candidate string) ([]byte, error) {
-        return fetchAndValidate(ctx, client, candidate)
-    },
-)
-```
-
-The callback owns HTTP requests, size limits, and content validation. The first
-completed valid result wins. Other operations are canceled and drained. There is
-no HEAD-probe assumption or client-specific HTTP behavior inside the executor.
-
-## Fallback: repository operations
-
-```go
-repo, err := githubmirror.Fallback(ctx, cfg.GithubMirror, officialURL,
-    githubmirror.Options[*git.Repository]{
-        Kind: githubmirror.Repository,
-    },
-    func(ctx context.Context, candidate string) (*git.Repository, error) {
-        // Use a clean temporary checkout for each attempt.
-        return clone(ctx, candidate)
-    },
-)
-```
-
-The official URL is attempted first; mirrors follow their configured order.
-jsDelivr is excluded for repositories. Stop on the first success. Perform
-persistent installation or other business state changes after success, rather
-than inside a potentially repeated attempt.
-
-## Results with resources
-
-For temporary files, set `Options[*Download].Discard` to remove the file. Return
-the partial `*Download` alongside errors, so cleanup also covers failed reads or
-validation. The executor discards every failure and every race loser exactly
-once. The caller owns and must track/release the winning result.
-
-- `Timeout == 0` uses 30 seconds per resource attempt and no overall deadline
-  for repository attempts; a negative timeout is invalid. Extension Git HTTP
-  transport limits connections/TLS handshakes to 10 seconds and resets a 60-second
-  read deadline as data arrives. Slow continuous transfers can finish, while
-  stalled sources fail and allow ordered fallback. Parent cancellation still applies.
-- Attempts must honor the supplied context; draining waits for them to return.
-- Attempt contexts are canceled after return, so callbacks must finish reading
-  HTTP bodies before returning. Returning a still-streaming response is unsupported.
-- Discard callbacks must accept zero values, must not panic, and run serially.
-- Parent cancellation wins over a result selected while the parent is canceled;
-  the selected result is then discarded as well.
-- Errors preserve their causes through wrapping/joining for `errors.Is`.
-- `github.com` and `raw.githubusercontent.com` expand into eligible mirrors.
-  jsDelivr is only eligible for raw source resources. `api.github.com` is never
-  mirrored and is rejected by the public mirror candidates API.
-- Client application update checks request the official GitHub API directly,
-  falling back to the independent Gopeed website API on request or validation
-  failure. Only package downloads obtain URLs from
-  `POST /api/v1/mirrors/github/candidates`. Candidate generation never performs
-  HTTP requests.
-- Disabled mirrors and other URLs execute only the original URL.
-- Config is a caller-owned immutable snapshot for the duration of a call.
