A refactor without a gate silently regrows, so this is the part that makes the
cap stick. Until now the repo had no root .pre-commit-config.yaml at all --
`git commit` ran zero hooks, and the five subproject configs only covered their
own directories.
Adds a root config wiring scripts/check_file_length.sh as a local hook, and
carries the same hook in each of the five subproject configs so committing
with one of those is gated too. Staged files only, so an unrelated commit
never breaks on a violation it did not introduce; exit 1, not a warning; no
baseline and no allowlist, since those are suppressions.
Verified in a throwaway worktree, both directions:
- a staged 261-line file fails the commit (exit 1, HEAD unchanged, no
commit object created)
- a staged 200-line file commits normally (exit 0)
The 44 files still over the cap cannot block this: the hook only ever sees
what a commit touches.

gatelock
Shared fullscreen lock-window + HMAC log-integrity backend, extracted from three personal automation tools that each independently implemented "lock the screen with a blocking overlay until a condition is met": diet_guard, wake_alarm, and screen-locker.
Why
All three reimplemented the same tkinter fullscreen mechanics (overrideredirect,
input grab, VT-switch disable) at different levels of maturity, and the
HMAC-signed-state module had already been hand-copied between two of them
because they live in separate repos. gatelock is the one place that logic
now lives.
Install
pip install "gatelock @ git+https://github.com/kuhyx/utils@gatelock-v0.1.1#subdirectory=gatelock"
Usage
import tkinter as tk
from gatelock import GateRoot, LockConfig, LockWindow
class MyGate:
def __init__(self, *, demo_mode: bool) -> None:
self.root = GateRoot()
self.root.on_callback_error = self._handle_callback_error
config = LockConfig(mode="soft" if demo_mode else "hard")
self._lock = LockWindow(self.root, config, hooks=self)
self._lock.setup()
# ... build your widgets ...
self._lock.grab_input()
def on_focus_ready(self) -> None:
self.my_entry.focus_force()
def on_callback_error(self) -> None:
self.close()
def on_close(self) -> None:
... # release any hardware/state held while locked
def close(self) -> None:
self._lock.close()
def run(self) -> None:
self._lock.run()
LockConfig's mode preset bundles the common combination ("soft" = topmost
only, typeable, WM-escapable; "hard" = overrideredirect + global grab +
VT-disable). Each axis (overrideredirect, grab, disable_vt,
grab_retry_ms) can be set explicitly to reproduce a consumer's exact prior
behavior where it diverges from the preset.
gatelock.log_integrity ports the HMAC-signed state module used by all three
projects; DEFAULT_HMAC_KEY_FILE (/etc/workout-locker/hmac.key) is
unchanged so existing signed history keeps verifying.
