- dep_ensure.py: use get_hermes_home() instead of hand-rolled env var - dep_ensure.py: add "chrome" to browser name list (was inconsistent with browser_tool.py) - main.py _cmd_update_check: use detect_install_method() directly instead of redundant .git check - main.py _cmd_update_pip: build command list directly instead of fragile split() on display string - banner.py: rename _check_via_pypi → check_via_pypi (cross-module public API)

"""Lazy dependency bootstrapper for non-Python runtime deps.
|
|
|
|
Detection and prompting live here in Python — not in install.sh — because:
|
|
1. shutil.which() works on every platform; install.sh needs bash.
|
|
2. Detection is instant; spawning bash for a "is node installed?" check is waste.
|
|
3. Python controls the UX (rich prompts, non-interactive fallback, TTY detection).
|
|
|
|
install.sh is still the *installation* backend because it has 1900 lines of
|
|
battle-tested OS detection and package-manager logic (apt/brew/pacman/dnf/
|
|
zypper/Termux/…). Reimplementing that in Python would be huge duplication.
|
|
|
|
Deps that degrade gracefully (ripgrep → grep fallback, ffmpeg → skip conversion)
|
|
don't need ensure_dependency wired in — only hard-fail sites do (TUI needs node,
|
|
browser tool needs agent-browser).
