Rename LabDAQ → LabUI and overhaul plugin system

2026-08-02T01:06:36Z

Branding: - Rename app, window title, file extension (.labdaq → .labui), user data dirs (~/.labui/), spec file (labdaq.spec → labui.spec), and APP_NAME throughout all source, docs, and config files Plugin system: - Plugins no longer bundled in the PyInstaller build — installed at runtime by users via Settings → Plugins → Install Plugin (zip) - PluginManager now takes user_dir + extra_scan_dirs; user plugins live in ~/.labui/plugins/, dev scan additionally covers project plugins/ - install_from_zip / uninstall / is_user_installed added to PluginManager - vendor/ dir inside plugin zips: prepended to sys.path at load time so plugins can ship their own deps without requiring pip on end-user machine - source_url field in manifest.json: shown as Download button in the missing-plugins dialog when a profile requires an absent plugin - Frozen-app pip install now targets ~/.labui/plugin_packages/ using a real system Python (sys.executable is the exe in frozen builds) Profile loading: - Profile now stores plugins_manifest snapshot (id, name, version, source_url) alongside plugins_enabled - On load, missing or dep-broken plugins trigger MissingPluginsDialog before the rest of the profile is applied; user can install from zip or download via source_url in-dialog, or cancel the load - Plugin reconciliation only enables installed plugins — missing ones are not written to enabled.json UI: - Version label added to status bar (bottom-right, muted colour) - Settings → Plugins tab: Install Plugin… button, per-plugin Remove button for user-installed plugins, live list refresh after install/remove Docs: - New docs/building.md covers the full release pipeline - docs/plugin-development.md updated for new install flow, vendoring, source_url, profile behaviour, and distribution instructions Co-Authored-By: Claude Sonnet 4.6

Added Motion Capture plugin

Tracks a user-selected point via webcam (OpenCV CSRT tracker) and streams x_pos / y_pos pixel coordinates as live channels into the acquisition pipeline. Falls back to a Lissajous figure simulation when opencv-python is not installed, so the plugin works immediately without hardware. - tracker.py: background thread, real camera + sim modes, thread-safe API - device.py: BaseDevice reading x/y from tracker, wires into engine - filter.py: custom pixel_to_mm filter (registered in FILTER_CLASSES) - window.py: floating tool window, live feed, click-to-track ROI selection - plugin.py: LabPlugin wiring all pieces together, toolbar button, settings widget, profile save/restore Also: PluginAction.button_ref_callback lets plugins store a ref to their toolbar button so they can uncheck it when their window closes. opencv-python install note added to requirements.txt.

Added plugin/add-on system

2026-06-03T15:50:17Z

Plugins live in plugins// with a manifest.json and a LabPlugin subclass. Enabled/disabled in Settings > Plugins tab; state persists in plugins/enabled.json and in .labdaq profiles (loading a profile enables/disables plugins to match). Plugins can contribute toolbar buttons, BaseDevice instances (auto-wired into acquisition pipeline), custom signal filter classes, a settings widget, and profile state via get_save_state/apply_save_state. Load errors now report the exact failing stage (file not found, class missing, on_load crash). Includes example plugin skeleton and docs/plugin-development.md. Co-Authored-By: Claude Sonnet 4.6
