The three google-workspace scripts (setup.py, google_api.py, gws_bridge.py)
each had their own way of resolving HERMES_HOME:
- setup.py imported hermes_constants (crashes outside Hermes process)
- google_api.py used os.getenv inline (no strip, no empty handling)
- gws_bridge.py defined its own local get_hermes_home() (duplicate)
Extract the common logic into _hermes_home.py which:
- Delegates to hermes_constants when available (profile support, etc.)
- Falls back to os.getenv with .strip() + empty-as-unset handling
- Provides display_hermes_home() with ~/ shortening for profiles
All three scripts now import from _hermes_home instead of duplicating.
7 regression tests cover the fallback path: env var override, default
~/.hermes, empty env var, display shortening, profile paths, and
custom non-home paths.
Closes#12722
- Rewrite test_google_workspace_api.py: test bridge token handling
and calendar date range instead of removed get_credentials()
- Update test_google_oauth_setup.py: partial scopes now accepted
with warning instead of rejected with SystemExit
Store the pending OAuth state and code verifier between --auth-url and --auth-code so the manual headless flow can reuse Flow.fetch_token() without disabling PKCE.
