Bulp v1.2.0

Bulp 1.2.0 prepares Bulp for Flathub.

⚠️ New app ID: reinstall the Flatpak

The app ID changed from de.codecauldron.Bulp to io.github.Nilpointer.Bulp. Flathub needs it, and it matches the repository, which moved from Nilpointer/bulps to Nilpointer/bulp (old links redirect).

If you installed the 1.1.0 Flatpak, replace it:

flatpak uninstall --user de.codecauldron.Bulp
flatpak install --user io.github.Nilpointer.Bulp.flatpak

The AppImage, the CLI and the Claude Code plugin need nothing special; just use the new downloads, or run claude plugin marketplace update bulps and claude plugin update bulp@bulps.

What's new

• Ready for Flathub:
  • The app metadata has screenshots.
  • packaging/flatpak/flathub/ has a manifest that builds this tag from git, fully offline.
  • packaging/flatpak/gen-go-sources.py lists every Go module as a checksummed download.
• Windows CLI binaries are part of every release now.
• README:
  • Installing the CLI on Linux without touching PATH.
  • Installing the CLI on Windows.
  • A guide to the Claude Code plugin.
  • A table of typical agent requests and the commands they run.

Bulp v1.1.0

Bulp 1.1.0 makes the bulp CLI easy to use from scripts and AI agents.

What's new

• JSON for scripts and agents: -json now prints one list with an entry per light: name, host, on, brightness, and kelvin (white lights) or hue/saturation (color lights).

  [{"name": "Desk Left", "host": "192.168.1.20:9123", "on": true, "brightness": 40, "kelvin": 3500}]

  ⚠️ This changes the JSON format of 1.0.0, which printed one object per light without its name and reported temperature in mireds.
• Several lights without discovery: BULP_HOST / -host take comma-separated addresses, e.g. BULP_HOST=192.168.1.20,192.168.1.21. Each light gets its real name, so -name desk works with them too.
• Agent skill: skills/bulp/SKILL.md teaches AI agents (Claude Code and others that support Agent Skills) how to control your lights. Install it with cp -r skills/bulp ~/.claude/skills/, then ask "dim the lights to 40%".
• README: new sections on scripts and AI agents and on automating lights out with cron, systemd timers or a headless agent.

The tray app and control panel are unchanged.

Highlights

• A tray icon with an on/off menu per light, and a control panel with power, brightness, color temperature, and hue and saturation for color lights.
• Lights are found automatically via Bonjour/mDNS, through Avahi when it's running (reliable even with lights on Wi-Fi). If multicast is blocked, pass -host with the lights' addresses.
• The app runs as a single instance: launching it again brings up the panel.
• On GNOME, the tray icon needs the AppIndicator extension. Without a tray, Bulp runs as just the panel window.

On macOS and Windows, use Elgato's official Control Center app (the bulp CLI works on macOS too).
