Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[4.5.8] - 2026-04-07

Fixed

  • kim uninstall now removes install-script binary — _detect_install_type() verifies the binary on PATH is in pip's RECORD before returning "pip". Orphaned pip metadata from a prior pip install no longer causes the uninstaller to skip ~/.local/bin/kim.
  • install.sh --uninstall works when piped from curl — reads confirmation from /dev/tty instead of stdin.
  • Both shell uninstall paths clean up orphaned pip metadata — silently runs pip uninstall kim-reminder as part of cleanup.

Added

  • uninstall.sh — standalone uninstall script. Works independently of install.sh, supports -y/--yes to skip confirmation. Usage: curl -fsSL https://raw.githubusercontent.com/pratikwayal01/kim/main/uninstall.sh | bash
  • -y/--yes flag for install.sh --uninstall skips the confirmation prompt.

[4.5.7] - 2026-04-07

Added

  • kim remove <N> — remove a recurring reminder by 1-based index as shown in kim list. Existing name-based removal still works unchanged.
  • kim list shows # index column — recurring reminders now display a 1-based index so users know what number to pass to kim remove.

[4.5.6] - 2026-04-07

Added

  • kim export --oneshots — include pending one-shot reminders in the export (JSON: "oneshots" array; CSV: appended section). Use with -o file to save to a file.
  • kim import --oneshots — restore pending one-shot reminders from a file produced by kim export --oneshots. Only future fire times are imported; duplicates are skipped.
  • Help footer now shows oneshots: ~/.kim/oneshots.json alongside the config and log paths.

Fixed

  • kim uninstall now kills orphaned kim remind fork children — on Linux the uninstall reads /proc directly to find and SIGTERM every sleeping kim remind child process. On macOS/other Unix it falls back to pkill -f. This prevents a one-shot reminder from firing after kim has been uninstalled.
  • kim uninstall clears oneshots.json before removing ~/.kim/ — even if a fork child survives the SIGTERM (e.g. already woken), the cleared file means it cannot write back or be replayed on any future kim start.

[4.5.5] - 2026-04-05

Fixed

  • Scheduler race condition — _wakeup.clear() is now called inside the lock so a wakeup signal set between reading the heap and entering wait() is never lost.
  • Scheduler: notifier now runs in a daemon thread — a slow or blocking notifier (e.g. Slack network call) no longer stalls the scheduler loop and delays all future firings.
  • One-shot reminders: remove from _live after firing — fired one-shots are now removed from the scheduler's internal _live dict, preventing a memory leak for long-running daemons.
  • One-shot fork child now calls remove_oneshot() — after the Unix os.fork() child fires a kim remind one-shot, it removes its entry from oneshots.json so the reminder does not re-fire on the next daemon start.
  • oneshots.json tmp file permissions — all atomic writes to oneshots.json (via .tmp rename) now chmod 0o600 the tmp file on Unix before the rename, preventing world-readable exposure.
  • Negative sleep_seconds on clock jump — kim remind now clamps sleep_seconds to max(0.0, ...) so a backward clock adjustment never causes time.sleep() to crash.
  • kim update --interval now validates the value — passing an invalid interval string (e.g. --interval foo) is rejected with an error message instead of silently writing bad data to config.
  • kim validate now checks at field format — reminders with an at field are validated to be in HH:MM format; invalid values are reported as errors.
  • Slack webhook response body checked — _notify_slack_webhook now reads the response body and logs a warning if it is not "ok". _notify_slack_bot reads the JSON response and logs the API error if ok is false.
  • kim interactive edit: clearing at when switching to interval — editing a reminder to set an interval now removes any existing at and timezone keys, preventing an invalid mixed-schedule state.
  • kim interactive add one-shot: urgency no longer hardcoded to critical — the user is now prompted for urgency (default: normal), consistent with kim remind.
  • load_config prints a warning on JSON corruption — callers (including the daemon and CLI) now see a stderr message when the config file is invalid JSON, not just a silent log entry.
  • kim (bare, no subcommand) now exits 0 — printing help is not an error condition.
  • sound.py: validate_sound_file now checks read permission — a file that exists but is not readable is rejected with a clear error message.
  • import re moved to module level in cli.py — the deferred import re inside _Formatter._format_actions_usage is now a top-level import.
  • import datetime moved to module level in misc.py — the deferred import datetime as _dt inside cmd_remind is now a top-level import.
  • cmd_remove exception handling narrowed — the bare except Exception when reading oneshots.json in cmd_remove is now except (json.JSONDecodeError, OSError).
  • Dead-code removal: KimScheduler.update_reminder and KimScheduler.disable_reminder (thin wrappers never called externally) removed; core.parse_interval marked deprecated (kept for backward compatibility).

[4.5.0] - 2026-04-05

Added

  • kim remind --urgency — one-shot reminders now accept --urgency low|normal|critical (default: normal), matching kim add behaviour. Urgency is persisted to ~/.kim/oneshots.json and correctly restored if the daemon restarts while the reminder is pending.

Fixed

  • kim start daemon detection — replaced INVOCATION_ID env-var check with a TTY check (/dev/tty). The old check caused kim start to block the terminal on some Linux distros because systemd inherits INVOCATION_ID to all child shells, not just supervised processes.
  • kim start / kim stop messages now include PID:
  • kim started. (PID 1234)
  • kim is already running. (PID 1234)
  • kim stopped. (PID 1234)
  • kim is already stopped.
  • kim remind output consistent with kim add — confirmation now uses the ✓ prefix instead of leaking the notification title into the CLI output line.
  • _remind-fire hidden from usage line — internal subcommand no longer appears in kim usage/help output.
  • --break-system-packages added to all pip calls — kim self-update and kim uninstall now work correctly on Arch Linux, Debian 12+, Ubuntu 23.04+, and other distros with externally managed Python environments.

Changed

  • Shell completions for bash, zsh, and fish updated to include --urgency for kim remind.

[4.1.8] - 2026-04-05

Fixed

  • _find_asset was orphaned dead code in selfupdate.py — the function body appeared after _parse_version's return statement making it unreachable, causing NameError at runtime during self-update. Extracted into a proper top-level function.
  • cmd_list did not display at-schedule reminders correctly — the INTERVAL column fell back to "30 min" for daily-at reminders. Now shows "at HH:MM" and the column is renamed SCHEDULE.
  • Interactive mode: cancel_oneshot name-shadowing crash — the local helper inside cmd_interactive was named remove_oneshot, shadowing the module-level import of the same name, causing a TypeError when cancelling a one-shot. Renamed to cancel_oneshot.

Tests

  • Added 77 new feature tests in tests/test_features.py covering: cmd_remind, oneshot load/remove, cmd_list, cmd_status, config reload, sanitize, export/import, _find_asset, scheduler reschedule, parse_interval/parse_datetime edge cases, and cmd_validate.
  • Added regression tests in tests/test_regression.py for _parse_version, downgrade guard, install-type detection order, interactive cancel_oneshot rename, and cmd_validate at-reminder acceptance.

[4.1.7] - 2026-04-05

Added

  • Interactive mode: List/Add/Remove One-shots — three new menu items in kim interactive for managing one-shot reminders without touching the CLI.
  • Interactive mode: --at HH:MM schedule — "Add Reminder" now prompts for interval or daily-at schedule type.
  • Status bar one-shot count — interactive header shows One-shots: N pending alongside the reminder count.
  • Config auto-reload after every action — interactive mode reloads config from disk after each mutation so the display is always current.

Fixed

  • kim help output cleanup — removed duplicate positional-args block, replaced long {start,stop,...} metavar with <command>, suppressed internal _remind-fire subcommand from help, removed redundant "Short flags" section, and tightened epilog formatting.
  • Interactive daemon signal on mutations — all mutating actions (add, edit, toggle, remove) now call _signal_reload() so the running daemon picks up changes immediately.

[4.1.6] - 2026-04-05

Fixed

  • kim uninstall WinError 32 — explicitly close all logging handlers before removing ~/.kim, releasing the file lock on kim.log on Windows.
  • kim uninstall "The batch file cannot be found." — the currently-running kim.bat is no longer deleted in-process. A detached cmd is spawned to remove it ~2 s after the process exits, so cmd.exe can return cleanly.
  • "Thank you for using kim!" is now always the last line of uninstall output.

[4.1.5] - 2026-04-05

Added

  • kim list -o / --oneshots — appends pending one-shot reminders to the list output, showing index, message, fire time, and time remaining.
  • kim remove <index|msg> -o / --oneshot — cancels a pending one-shot by its list index (from kim list -o) or message substring, instead of removing a config reminder.

Removed

  • kim remind --list and kim remind --cancel flags removed in favour of the cleaner kim list -o / kim remove -o interface.

[4.1.4] - 2026-04-05

Added

  • kim remind --list — show all pending one-shot reminders with index, message, fire time, and time remaining.
  • kim remind --cancel <index|message> — cancel a pending one-shot by its list index (from --list) or a message substring match.

[4.1.3] - 2026-04-05

Fixed

  • Windows script install: kim start crash (WinError 193) — _spawn_detached() was calling Popen(sys.argv) which fails when sys.argv[0] is a .py file (script install via install.ps1). Now prepends sys.executable when argv[0] ends in .py on Windows.

[4.1.2] - 2026-04-05

Fixed

  • Windows PATH instructions — README now shows a copy-paste one-liner to fix PATH after pip install. install.ps1 also auto-fixes the pip Scripts PATH for users who already installed via pip.

[4.1.1] - 2026-04-05

Fixed

  • Windows PATH auto-fix — on Windows, kim now detects if the pip Scripts directory is missing from the user PATH and adds it automatically via setx on first run. Users no longer need to manually update their PATH after pip install kim-reminder.

[4.1.0] - 2026-04-05

Added

  • --every flag — alias for -I/--interval on kim add and kim update (e.g. kim add "drink water" --every 30m)
  • --at HH:MM on kim add/kim update — schedule a reminder to fire every day at a fixed time (e.g. kim add standup --at 10:00). Mutually exclusive with --interval.
  • --tz TZ flag — IANA timezone override for --at and kim remind ... at (e.g. --tz Asia/Kolkata). Defaults to local system timezone.
  • kim remind ... at <datetime> — fire a one-shot reminder at an absolute datetime. Accepts natural language and ISO formats:
  • at 14:30 — today at 14:30 (or tomorrow if already past)
  • at tomorrow 10am — tomorrow at 10:00
  • at friday 9am — next Friday at 09:00
  • at 2026-04-06 09:00 — specific date and time
  • parse_datetime utility — pure stdlib datetime parser in core.py supporting both relative (in 10m, 2h 30m) and absolute (at tomorrow 9am) formats
  • parse_at_time utility — validates and normalises --at HH:MM values
  • Scheduler support for daily at-time reminders — KimScheduler now handles reminders with an at field; re-schedules them for the same wall-clock time the next day after firing
  • Live config reload — kim add, kim remove, kim enable, kim disable, and kim update now take effect in the running daemon within 1 second — no restart needed. Implemented via a ~/.kim/kim.reload flag file polled by the daemon loop. On Linux/macOS, kill -HUP <pid> also triggers a reload.

Changed

  • kim start no longer blocks the terminal — when run interactively it spawns a detached background process and returns immediately. Process supervisors (systemd, launchd, Windows Task Scheduler) are detected automatically and still run in-process.
  • kim start output — shows kim started. (PID 1234) on fresh start; shows kim is already running. (PID 1234) if the daemon is already up.
  • kim stop output — shows kim stopped. (PID 1234) on success; shows kim is already stopped. if not running.
  • kim status running line — now shows ● kim running (PID 1234) for consistency with start/stop output.
  • kim remind time-parsing refactored to use parse_datetime (behaviour-compatible for existing relative syntax)

[4.0.0] - 2026-04-02

Added

  • Per-reminder sound overrides — each reminder can specify its own sound_file or disable sound
  • Per-reminder Slack overrides — route individual reminders to different Slack channels or webhooks
  • Log rotation — RotatingFileHandler with 5 MB max, 3 backups (prevents unbounded log growth)
  • Full shell completions — bash/zsh/fish now complete subcommand flags, reminder names, and file paths
  • One-shot reminder persistence docs — documented ~/.kim/oneshots.json format and behavior
  • Interval seconds support — 90s now a valid interval format alongside 30m, 1h, 1d

Changed

  • Atomic PID file writes — writes to .tmp then renames, eliminating partial-write corruption
  • Direct Python spawn on Windows — one-shot reminders no longer go through PowerShell (saves 1-2s startup overhead)
  • kim update --enable/--disable — fixed broken flag logic (was using is not None on booleans)
  • kim update -I/--interval — changed from int to string to match kim add (accepts 30m, 1h, etc.)
  • kim remind parser — bare numbers treated as minutes, max duration clamped to 365 days
  • kim with no command — now exits with code 1 instead of silently returning

Fixed

  • Critical: Slack bot urgency bug — _notify_slack_bot() referenced undefined urgency variable (NameError crash)
  • Critical: Slack emoji bug — emoji = urgency_emoji.get("normal", ":bell:") hardcoded "normal" instead of using actual urgency
  • Critical: Missing platform sound functions — _play_system_sound_mac() and _play_system_sound_linux() were called but never defined (crash on default sound)
  • PID file TOCTOU race — stale PIDs from crashed processes caused false "already running" errors; now verifies process is alive
  • Config shallow copy bug — DEFAULT_CONFIG.copy() shared nested dict references between callers; now uses copy.deepcopy()
  • Config defaults missing — load_config() now fills in all missing sound, sound_file, and slack sub-fields
  • Interval parser edge cases — empty string, zero, and negative values now return safe default (30 min) instead of crashing
  • One-shot child process crash — forked child on Unix now wrapped in try/except/finally to prevent silent daemon crashes
  • One-shot Windows spawn — added FileNotFoundError handling for missing PowerShell
  • Startup notification crash — wrapped in try/except so notification failure doesn't kill the daemon
  • Config write permissions — all 8+ config write paths now set 0o600 on Unix and use encoding="utf-8"
  • F-string log calls — 26 instances converted to %-formatting for lazy evaluation (no string formatting when log level is suppressed)
  • Redundant imports — removed duplicate import urllib.request / import urllib.error inside functions
  • Dead code — removed platform_notifier(), start_daemon() shim, --HELP pseudo-flag, -V/--VERSION aliases
  • Fish completion — removed broken shebang, added full subcommand flag completions
  • Bash/Zsh completions — removed broken shebangs, added remind and _remind-fire commands
  • Duplicate FISH_COMPLETION — removed second definition that overwrote the first

Removed

  • Non-standard CLI flags: -V, --VERSION, --HELP
  • Stale "Config changes are detected automatically" claim from README (no file watcher exists)
  • Completed roadmap items (all features now shipped)

Security

  • All config writes set 0o600 permissions on Unix (Slack tokens protected)
  • PID file written atomically with 0o600 permissions
  • Log file set to 0o600 on Unix
  • Secrets (webhook URLs, bot tokens) never appear in log messages
