hermes --tui launches the native OpenTUI engine (Bun) when
HERMES_TUI_ENGINE=opentui (env) or display.tui_engine=opentui (config);
Ink stays the default and the shipping path is untouched.
- _resolve_tui_engine() (env > config > ink); refuses opentui on
Windows/Termux (no Bun) -> falls back to ink with a notice.
- _make_opentui_argv() -> [bun, src/entry.real.tsx] (no build step).
- _bun_bin() with HERMES_BUN override.
- Branch at top of _make_tui_argv BEFORE _ensure_tui_node (Bun-only host
must not bootstrap Node).
- Gate _launch_tui NODE_OPTIONS/--max-old-space-size on engine==ink (Bun
is JSC; the V8 flag errors/ignores).
Verified end-to-end via tmux: real hermes --tui -> Bun -> OpenTUI ->
real Python gateway streamed a real reply. No-flag default still ink.
Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
Problem:
After `hermes profile use NAME`, the gateway (started via systemd with
HERMES_HOME=/root/.hermes hardcoded) ignores the active profile and
always runs as the Default profile. WebUI, Telegram, and all non-CLI
platforms are affected.
Root cause:
_apply_profile_override() contained an early-return guard:
if profile_name is None and os.environ.get("HERMES_HOME"):
return # trust the inherited value
The intent was to let child processes inherit their parent's profile via
HERMES_HOME without redundantly re-reading active_profile. But
systemd also sets HERMES_HOME — to the hermes root (/root/.hermes),
not a profile directory — so the guard fired and silently skipped the
active_profile check. The user's `hermes profile use NAME` write to
~/.hermes/active_profile was never seen by the gateway process.
Fix:
Only skip the active_profile check when HERMES_HOME is already a
profile directory, identified by its immediate parent directory being
named "profiles" (e.g. ~/.hermes/profiles/coder or
/opt/data/profiles/coder). When HERMES_HOME points to a root
directory (parent name != "profiles"), continue to read active_profile.
Tests:
- test_hermes_home_at_root_with_active_profile_is_redirected: the
bug scenario — HERMES_HOME=/root/.hermes + active_profile=coder →
HERMES_HOME must be redirected to .../profiles/coder.
Stash-verified: FAILS without fix, PASSES with fix.
- test_hermes_home_already_profile_dir_is_trusted: child-process
inheritance contract unchanged — .../profiles/coder is trusted as-is.
- test_hermes_home_unset_reads_active_profile: classic path unchanged.
- test_hermes_home_unset_default_profile_no_redirect: "default" still
produces no redirect.
4/4 tests green.
Closes#22502.
