Add a Russian translation of the app

This adds a complete Russian translation of the RemoveMacAI window. English stays the source language and nothing changes for English users. The CLI output also stays as it is.

What it adds

  • Localization/ru.lproj/Localizable.strings: 410 entries. Keys are the English strings exactly as they appear in the code.
  • Localization/ru.lproj/Localizable.stringsdict: 7 entries with Russian plural forms (one / few / many / other). For example "1 настройка", "2 настройки", "5 настроек", "21 настройка".
  • Sources/removemacai/App/L10n.swift, a small helper:
    • L(_:) looks up a fixed English string in Bundle.main and returns the English when there is no entry.
    • UISize.of(_:) is Term.size with the unit translated ("ГБ") and the region's decimal separator.
    • localizedMessage(_:) translates the one engine caveat that is built from parts (the GarageBand sound-library note).
  • tools/build-app.sh copies Localization/*.lproj into Contents/Resources. It also writes CFBundleLocalizations from the folders it finds, which is en plus each <language>.lproj.
  • tools/check-localization.py <language> lists window text that has no translation and exits 1 if there is any. It turns interpolations into %lld / %@ the way SwiftUI and String(localized:) build keys.
  • A short "Translations" paragraph in CONTRIBUTING.md.

How strings are looked up

  • SwiftUI literals (Text("…"), Button("…"), Section("…"), .help("…") and so on) were already LocalizedStringKeys and need no change.

  • Text that reached the window as a String was always shown verbatim. This covers tweak titles, details and caveats, group titles and summaries, presets, Apple Intelligence features and blurbs, model sets, storage items, help popovers, promises and step cards. It now goes through L() at the place it is displayed, or through String(localized:) where the text is built with interpolation.

    • The data in Tweaks.swift, Catalog.swift and Storage.swift is unchanged, so the CLI, the journal and status output are unaffected.
  • A few helpers now take LocalizedStringKey instead of String, so their literal call sites are localized like any other SwiftUI text: Footer, chip, step, stepRow, stepCard, SafetyCard.check and StatTile's title and link.

  • Sentences that were glued together from English pieces are now whole sentences, so they can be translated:

    • "couldn't be (remove ? "removed" : "installed")"
    • "snapshot(s)"
    • "item(s) … it was/they were"
    • "feature(s) is/are kept on"
    • "N settings(models)"
    • "kept feature(s)"

    The English text is identical.

  • The background-item warning is rebuilt in the view from item.owner, under the same condition as item.warning.

  • The two administrator password prompts use String(localized:).

Fallback

  • Any missing key falls back to the English text in the code.
  • The bare removemacai binary has no .lproj next to it, so the CLI is English as before.
  • English users see exactly what they saw before (compared with snapshots under -AppleLanguages '(en)').

What stays English on purpose

  • Product and feature names Apple doesn't translate in Russian macOS: Apple Intelligence, Siri, Genmoji, Image Playground, Finder, Dock, Time Machine, Game Center and so on.
  • The exact commands and profile keys shown under "Show exact settings", and background-item labels and paths.
  • Low-level error text from the engine that includes tool output, for example "could not disable : …".

Adding another language

  1. Copy Localization/ru.lproj to Localization/<language>.lproj and translate the values.
  2. Run tools/check-localization.py <language> until it reports 0.
  3. tools/build-app.sh picks the folder up and adds it to CFBundleLocalizations automatically.

Testing

  • macOS 15.7.4 (24G517), arm64, MacBook Air M2, Swift 6.2.3 (Command Line Tools 26.2).
  • Release build, then removemacai selftest: all checks passed.
  • tools/check-localization.py ru: 417 entries, 0 strings without a translation.
  • tools/build-app.sh produces a bundle with ru.lproj and CFBundleLocalizations = (en, ru). codesign --verify --strict passes.
  • Debug-build snapshots with REMOVEMACAI_SNAPSHOTS, REMOVEMACAI_SNAPSHOTS_WELCOME and REMOVEMACAI_SNAPSHOTS_REVIEW:
    • With -AppleLanguages '(ru)': all 24 pages and sheets show Russian. Plural forms are correct, and no text is truncated except long setting names wrapping as English ones do.
    • With -AppleLanguages '(en)': unchanged.

Note: on this machine swift build fails because of a broken Command Line Tools install (the package manifest won't link, and a stale usr/include/swift/module.modulemap clashes with the SDK). So I compiled the same sources with swiftc directly and ran tools/build-app.sh against that binary. CI on macos-26 should build it the normal way.

This is one change: the translation and what it needs in order to show up. A CI step that runs tools/check-localization.py ru could be a follow-up if you want it.

Summary by CodeRabbit

  • New Features

    • Added Russian translations across the app, including onboarding, settings, Apple Intelligence controls, cleanup, privacy, errors, and status messages.
    • Added localized plural forms and region-appropriate storage size formatting.
    • Localized help, accessibility text, administrator prompts, confirmations, and completion messages.
    • App builds now include available localization resources.
  • Documentation

    • Added contributor guidance for adding and validating translations.
  • Chores

    • Added a checker that reports untranslated user-facing text.

Every string the window shows now goes through the bundle's
Localizable.strings: SwiftUI literals as before, and the English text that
comes from Tweaks, Catalog, Storage, presets and help through L() or
String(localized:). Counts use Localizable.stringsdict, so Russian gets its
plural forms, and sentences that were glued together from English pieces
("removed"/"installed", "snapshot(s)", "item(s)") are whole sentences now.

tools/build-app.sh copies Localization/*.lproj into the app and lists the
languages in CFBundleLocalizations. English stays the source language: a
missing key, or the bare CLI binary, shows the English text unchanged.

tools/check-localization.py ru lists English UI strings without a
translation and exits 1 if there are any.

📝 Walkthrough

The app adds a Russian localization catalog and applies localized text and size formatting across its UI and selected operation messages. The build script bundles localization resources, and a new tool checks Swift source literals for missing translations.

Layer / File(s) Summary
Localization catalog and lookup helpers
Localization/ru.lproj/Localizable.strings, Localization/ru.lproj/Localizable.stringsdict, Sources/removemacai/App/L10n.swift

Applies localized strings and keys to onboarding, help, navigation, review, status, and content views. Size displays use localized formatting.
Localize action and error messages
Sources/removemacai/App/AppModel.swift, Sources/removemacai/BackgroundItems.swift, Sources/removemacai/Storage.swift
Localizes profile, model-removal, undo, storage-cleanup, and administrator-password messages. Existing workflows and error handling remain unchanged.
Bundle resources and check translations
tools/build-app.sh, tools/check-localization.py, CONTRIBUTING.md
The build script copies localization resources and sets supported localizations. A new checker scans Swift literals for missing translations. Contributor guidance documents the localization files and checker command.

- Line 18: Update the key-matching expression used by the re.finditer call in
the localization checker to allow optional whitespace before the opening quote,
while preserving the existing quoted-key and assignment matching behavior.
- Line 64: Update the NOT_UI regular expression so the placeholder exclusion
matches only strings consisting entirely of a supported placeholder, not strings
with additional text such as “%@ is ready”. Preserve filtering for other non-UI
patterns while ensuring sentences beginning with %@ or %d are still reported as
missing translations.
