LGTM — clean, mechanical localization with no behavior changes.
Verified:
- The Rust changes across the 38 CLI/TUI files are pure string →
i18n::t/t_argsreplacements. Spot-checked the largest (commands/skill.rs, +493/-133) — all of it isi18n::t_args(...)call conversions, no logic changes. i18n::t/t_argsfall back to the defaultenlanguage when a key is missing (i18n.rs), so partial locales degrade to English rather than showing raw keys.- CI is green.
One non-blocking note: the zh-CN locale is ~55% complete — 870 keys vs en 1590 / uk 1589. Chinese-locale users will see English for the ~720 untranslated keys. Acceptable given the graceful en fallback, but worth tracking completion of zh-CN in a follow-up so the experience isn't half-English. uk is essentially complete.
Approving.

Summary
This PR localizes the core CLI TUI main interface (
tui/mod.rs), the TUI Welcome screen (tui/screens/welcome.rs), the Sessions screen (tui/screens/sessions.rs), and the Peers screen (tui/screens/peers.rs) to support English, Ukrainian, and Simplified Chinese.All user-facing strings are refactored to use Fluent localization keys. Pluralization logic is implemented cleanly via Fluent templates.
Changes
Source Code Refactoring (
crates/librefang-cli/src/)[MODIFY] mod.rs
crate::i18n::tandcrate::i18n::t_args.chat-runner-keys for general messages (e.g. model switching, connection errors) to maintain consistency.Tab::label(self)to load localized tab names dynamically from Fluent.[MODIFY] welcome.rs
MenuItemstruct) to hold ownedStringlabels and hints instead of static&'static strlifetimes to support dynamic localization.tui-welcome-agent-count) for active daemon agent display.[MODIFY] sessions.rs
[MODIFY] peers.rs
Localization Files (
crates/librefang-cli/locales/)[MODIFY] en/main.ftl
tui-tab-*), welcome screen items (tui-welcome-*), sessions screen (tui-sessions-*), and peers screen (tui-peers-*).[MODIFY] uk/main.ftl
[MODIFY] zh-CN/main.ftl
Testing
Clean build with no warnings:
All 240+ unit/integration tests in the workspace pass successfully.
Verified that the interactive TUI boots up correctly, displays localized tab names and welcoming options, and handles sessions/peers layout and actions flawlessly under different locales.
