feat(i18n): add display.language for static message translation (zh/ja/de/es) (#20231)
* revert(gateway): remove stale-code self-check and auto-restart Removes the _detect_stale_code / _trigger_stale_code_restart mechanism introduced in #17648 and iterated in #19740. On every incoming message the gateway compared the boot-time git HEAD SHA to the current SHA on disk, and if they differed it would reply with Gateway code was updated in the background -- restarting this gateway so your next message runs on the new code. Please retry in a moment. and then kick off a graceful restart. This is unwanted behaviour: users who run a long-lived gateway and do their own ad-hoc git operations on the checkout end up with their chat interrupted and the current message dropped every time HEAD moves, with no way to opt out. If an operator really needs the old protection against stale sys.modules after "hermes update", the SIGKILL-survivor sweep in hermes update (hermes_cli/main.py, also tagged #17648) already handles the supervisor-respawn case on its own. Removed: gateway/run.py: - _STALE_CODE_SENTINELS, _GIT_SHA_CACHE_TTL_SECS - _read_git_head_sha(), _compute_repo_mtime() module helpers - class-level _boot_wall_time / _boot_repo_mtime / _boot_git_sha / _stale_code_restart_triggered defaults - __init__ boot-snapshot block (_boot_*, _cached_current_sha*, _repo_root_for_staleness, _stale_code_notified) - _current_git_sha_cached(), _detect_stale_code(), _trigger_stale_code_restart() methods - stale-code check + user-facing restart notice at the top of _handle_message() tests/gateway/test_stale_code_self_check.py (deleted, 412 lines) No new logic added. Zero remaining references to any removed symbol. Gateway test suite passes the same 4589 tests it passed before; the 3 pre-existing unrelated failures (discord free-channel, feishu bot admission, teams typing) are unchanged by this commit. * feat(i18n): add display.language for static message translation (zh/ja/de/es) Adds a thin-slice i18n layer covering the highest-impact static user-facing messages: the CLI dangerous-command approval prompt and a handful of gateway slash-command replies (restart-drain, goal cleared, approval expired, config read/save errors). Out of scope (stays English): agent responses, log lines, tool outputs, slash-command descriptions, error tracebacks. Infrastructure: - agent/i18n.py: catalog loader, t() helper, language resolution (HERMES_LANGUAGE env var > display.language config > en) - locales/{en,zh,ja,de,es}.yaml: ~19 translated strings per language - display.language in DEFAULT_CONFIG (hermes_cli/config.py) Tests: - tests/agent/test_i18n.py: 21 tests covering catalog parity, placeholder parity across locales, fallback behavior, env-var override, alias normalization, missing-key graceful degradation. Docs: - website/docs/user-guide/configuration.md: display.language entry plus a short section explaining scope so users don't expect agent responses to translate via this knob.

"""Lightweight internationalization (i18n) for Hermes static user-facing messages.
|
||||
|
||||
Scope (thin slice, by design): only the highest-impact static strings shown
|
||||
to the user by Hermes itself -- approval prompts, a handful of gateway slash
|
||||
command replies, restart-drain notices. Agent-generated output, log lines,
|
||||
error tracebacks, tool outputs, and slash-command descriptions all stay in
|
||||
English.
|
||||
|
||||
Catalog files live under ``locales/<lang>.yaml`` at the repo root. Each
|
||||
catalog is a flat dict keyed by dotted paths (e.g. ``approval.choose`` or
|
||||
``gateway.approval_expired``). Missing keys fall back to English; if English
|
||||
is missing too, the key path itself is returned so a broken catalog never
|
||||
crashes the agent.
|
||||
|
||||
Usage::
|
||||
|
||||
from agent.i18n import t
|
||||
print(t("approval.choose_long")) # current lang
|
||||
print(t("gateway.draining", count=3)) # {count} formatted
|
||||
print(t("approval.choose_long", lang="zh")) # explicit override
|
||||
|
||||
Language resolution order:
|
||||
1. Explicit ``lang=`` argument passed to :func:`t`
|
||||
2. ``HERMES_LANGUAGE`` environment variable (for tests / quick override)
|
||||
3. ``display.language`` from config.yaml
|
||||
4. ``"en"`` (baseline)
|
||||
|
||||
Supported languages: en, zh, ja, de, es. Unknown values fall back to en.

### UI language for static messages
|
||||
|
||||
The `display.language` setting translates a small set of static user-facing messages — the CLI approval prompt, a handful of gateway slash-command replies (e.g. restart-drain notices, "approval expired", "goal cleared"). It does **not** translate agent responses, log lines, tool output, error tracebacks, or slash-command descriptions — those stay in English. If you want the agent itself to reply in another language, just tell it in your prompt or system message.
|
||||
|
||||
Supported values: `en` (default), `zh` (Simplified Chinese), `ja` (Japanese), `de` (German), `es` (Spanish). Unknown values fall back to English.
|
||||
|
||||
You can also set this per-session with the `HERMES_LANGUAGE` env var, which overrides the config value.
|
||||
|
||||
```yaml
|
||||
display:
|
||||
language: zh # CLI approval prompts appear in Chinese
