 # Changelog

+## 2025-10-23 - 5.1.2 - fix(scripts)
+Add build script to package.json and include local dev tool settings
+
+- Add a 'build' script to package.json (no-op placeholder) to provide an explicit build step
+- Minor scripts section formatting tidy in package.json
+- Add a hidden local settings file for development tooling permissions to the repository (local-only configuration)
+
+## 2025-10-23 - 5.1.1 - fix(tooling)
+Add .claude/settings.local.json with local automation permissions
+
+- Add .claude/settings.local.json to specify allowed permissions for local automated tasks
+- Grants permissions for various developer/CI actions (deno check/lint/fmt, npm/npm pack, selective Bash commands, WebFetch to docs.deno.com and code.foss.global, and file/read/replace helpers)
+- This is a developer/local tooling config only and does not change runtime code or package behavior
+
+## 2025-10-22 - 5.1.0 - feat(packaging)
+Add npm packaging and installer: wrapper, postinstall downloader, publish workflow, and packaging files
+
+- Add package.json (v5.0.5) and npm packaging metadata to publish @serve.zone/nupst
+- Include a small Node.js wrapper (bin/nupst-wrapper.js) to execute platform-specific precompiled binaries
+- Add postinstall script (scripts/install-binary.js) that downloads the correct binary for the current platform and sets executable permissions
+- Add GitHub Actions workflow (.github/workflows/npm-publish.yml) to build binaries, pack and publish to npm, and create releases
+- Add .npmignore to keep source, tests and dev files out of npm package; keep only runtime installer and wrapper
+- Move example action script into docs (docs/example-action.sh) and remove the top-level example-action.sh
+- Include generated npm package artifact (serve.zone-nupst-5.0.5.tgz) and npmextra.json
+
 ## 2025-10-18 - 4.0.0 - BREAKING CHANGE(core): Complete migration to Deno runtime

+# This script is called by NUPST when power events or threshold violations occur.

+# ARGUMENTS (positional parameters)
+# ==============================================================================
+# $1 = Power Status (online|onBattery|unknown)
+# $2 = Battery Capacity (percentage, 0-100)
+# $3 = Battery Runtime (estimated minutes remaining)

+# ==============================================================================

+# ==============================================================================
+# NUPST_UPS_ID               - Unique UPS identifier
+# NUPST_UPS_NAME             - Human-readable UPS name
+# NUPST_POWER_STATUS         - Current power status
+# NUPST_BATTERY_CAPACITY     - Battery percentage (0-100)
+# NUPST_BATTERY_RUNTIME      - Estimated runtime in minutes
+# NUPST_THRESHOLDS_EXCEEDED  - "true" if below configured thresholds
+# NUPST_TRIGGER_REASON       - "powerStatusChange" or "thresholdViolation"
+# NUPST_BATTERY_THRESHOLD    - Configured battery threshold percentage

Juergen Kunz	3e15a2d52f	fix(action): correct message about config reload The daemon already has automatic config file watching and reloads changes without requiring a restart. Updated action handler messages to correctly reflect this behavior. Changed: - 'Restart service to apply changes: nupst service restart' → 'Changes saved and will be applied automatically' The config file watcher (daemon.ts:986) uses Deno.watchFs() to monitor /etc/nupst/config.json and automatically calls reloadConfig() when changes are detected. No restart needed.	2025-10-20 12:42:31 +00:00

Juergen Kunz	1ca05e879b	feat(action): add group action support Extended action management to support groups in addition to UPS devices: Changes: - Auto-detects whether target ID is a UPS or group - All action commands now work with both UPS and groups: * nupst action add <ups-id\|group-id> * nupst action remove <ups-id\|group-id> <index> * nupst action list [ups-id\|group-id] - Updated ActionHandler methods to handle both target types - Updated help text and usage examples - List command shows both UPS and group actions when no target specified - Clear labeling in output distinguishes UPS actions from group actions Example usage: nupst action list # Shows all UPS and group actions nupst action add dc-rack-1 # Adds action to group 'dc-rack-1' nupst action remove default 0 # Removes action from UPS 'default' Groups can now have their own shutdown actions, allowing fine-grained control over group behavior during power events.	2025-10-20 12:34:47 +00:00

Juergen Kunz	ff433b2256	feat(cli): add action management commands Added comprehensive action management: Commands: - nupst action add <ups-id> - Add a new action to a UPS interactively - nupst action remove <ups-id> <index> - Remove an action by index - nupst action list [ups-id] - List all actions (optionally for specific UPS) Features: - Interactive prompts for action configuration - Battery and runtime threshold configuration - Trigger mode selection (onlyPowerChanges, onlyThresholds, powerChangesAndThresholds, anyChange) - Shutdown delay configuration - Table-based display of actions with indices - Support for managing actions across multiple UPS devices Implementation: - Created ActionHandler class in ts/cli/action-handler.ts - Integrated with existing CLI infrastructure - Added to nupst.ts, cli.ts, and help system - Proper TypeScript typing throughout Closes the gap where users had to manually edit config.json to manage actions.	2025-10-20 12:32:14 +00:00

Juergen Kunz	b6b7b43161	refactor: replace 'any' types with proper TypeScript interfaces Major type safety improvements throughout the codebase: - Updated DEFAULT_CONFIG version to 4.2 - Replaced 'any' with proper types in systemd.ts: * displaySingleUpsStatus now uses IUpsConfig and NupstSnmp types * Fixed legacy config handling to use proper IUpsConfig format * Removed inline 'any' type annotations - Replaced 'any' with proper types in daemon.ts: * emergencyUps now properly typed as { ups: IUpsConfig, status: ISnmpUpsStatus } * Exported IUpsStatus interface for reuse * Added ISnmpUpsStatus import to disambiguate from daemon's IUpsStatus - Replaced 'any' with Record<string, unknown> in migration system: * Updated BaseMigration abstract class signatures * Updated MigrationRunner.run() signature * Updated migration-v4.0-to-v4.1.ts to use proper types * Migrations use Record<string, unknown> because they deal with unknown config schemas that are being upgraded Benefits: - TypeScript now catches type errors at compile time - Would have caught the ups.thresholds bug earlier - Better IDE autocomplete and type checking - More maintainable and self-documenting code	2025-10-20 12:27:02 +00:00

Juergen Kunz	4debda856b	fix(status): update status display to use action-based thresholds The status command was still trying to access ups.thresholds.battery which no longer exists in v4.1+ configs. Thresholds are now in the actions array. Changes: - Updated displaySingleUpsStatus() to get thresholds from actions - Finds first action with thresholds defined for battery symbol display - Shows success/warning symbol only if threshold is defined This fixes 'Cannot read properties of undefined (reading battery)' error when running nupst status on v4.1+ configs.	2025-10-20 12:20:40 +00:00

Juergen Kunz	7bf65d8495	fix(migrations): revert to correct migration v4.0-to-v4.1 The migration was correct as v4.0→v4.1. Config version goes from 4.0 to 4.1 when thresholds are moved to actions. The original error was not the migration but the ups-handler.ts bug (already fixed in v4.2.1). User's config shows version "4.1" with actions already present, confirming the migration ran successfully.	2025-10-20 12:17:03 +00:00

Juergen Kunz	8c1be6555f	fix(migrations): correct migration version from v4.0-to-v4.1 to v4.1-to-v4.2 The migration was incorrectly named as v4.0→v4.1 but was actually performing the v4.1→v4.2 migration (moving thresholds from UPS-level to action-level). This meant users upgrading from v4.1 would not get their configs migrated. Changes: - Renamed migration file from migration-v4.0-to-v4.1.ts to migration-v4.1-to-v4.2.ts - Updated class name from MigrationV4_0ToV4_1 to MigrationV4_1ToV4_2 - Updated fromVersion from '4.0' to '4.1' - Updated toVersion from '4.1' to '4.2' - Updated shouldRun() to check for config.version === '4.1' - Updated all imports and exports to reference the new class name - Updated comments and log messages to reflect v4.1→v4.2 migration	2025-10-20 12:14:02 +00:00
