Rework channel labeling and add source picker to virtual-channel creation

2026-07-29T19:10:35Z

Relabel every channel picker/header to "NAME (DEVICE/SIGNAL)" instead of the previous "DEVICE/SIGNAL (NAME)" ordering, consistently across channels_window.py (_channel_combo, ChannelPickerDialog, ChannelPipelineBlock header), plot_builder.py, plot_config.py, control_editor.py, and plot_window.py. While touching each of those pickers, added the missing `.enabled` filter that _make_picker()/_x_cb/_build_channel_picker lacked (the default-layout builders already filtered disabled channels; these manual "add channel to pane" pickers didn't). Devices window Signals tab: removed the separate "Signal ID" column (folded into the existing non-editable Device column instead of the editable Name column, to avoid corrupting the in-place channel rename feature that column already supports). Channels window Virtual Channels pane: added a "Source" dropdown next to "+ Add Channel" — picking a source pre-seeds the new derived channel with it via DerivedBlock._add_src(); leaving it on the default "none" entry keeps today's behavior of creating an empty channel. Note: docs/ToDo.md's "Channels window UI" items referred to the *live* UI (this window's PipelineTab + the Devices window's Signals tab), not SignalsListTab in this same file, which its own module docstring flags as dead/unused code kept only for old-profile compatibility — verified by grepping for any instantiation of it (none exist).

Derived channels: signal display names as vars, auto-update template code, None op

2026-06-10T05:18:43Z

- Variable names derived from signal display name (e.g. "Acceleration X" → acceleration_x) instead of raw channel ID; all auto-names lowercase with underscores - Template code auto-updates x[0]/x[1] refs to named vars as sources are added/changed; stops updating once user edits the code manually - Derivative wrt-channel mode uses separate template with x[1] substituted to channel var - Added "None" passthrough operation (result = x[0]) - source_names persisted in .labdaq profiles Co-Authored-By: Claude Sonnet 4.6

Fix custom_script execution + add templates for expression/function kinds

2026-06-10T04:35:40Z

- custom_script now uses exec-style (assign to `result`) matching the built-in templates — previously auto-wrapped in def compute() which had no return statement, causing state and channel vars to silently fail - function kind unchanged: auto-wraps body as def compute(x,t); use return - Add SCRIPT_TEMPLATES for expression, function, custom_script kinds; shown automatically when user switches to a script kind (replacing stale code from previous kind) - New channels default to template when no saved code exists Co-Authored-By: Claude Sonnet 4.6

Channels: inject variable names as comment in code editor, fix derivative wrt

2026-06-10T04:27:44Z

- Variable names now appear as a live '# Variables: A0 = x[0] · ...' comment at the top of the code editor (function, custom_script, and built-in read-only templates); updates on every source add/remove/change - Derivative 'With Respect To' channel combo now included in variable list as x[1] when channel mode is selected - _apply() strips the auto-generated comment before saving the script so it doesn't pollute the stored expression Co-Authored-By: Claude Sonnet 4.6

Channels: live variable-name hint in code editor updates with sources

2026-06-10T04:21:01Z

When sources are added, removed, or changed in the derived channel editor, the code group now shows a live "Variables: A0 = x[0] · encoder = x[1]" hint above the code editor so users know the exact names to use in scripts. Co-Authored-By: Claude Sonnet 4.6

Scripting: named signal vars, shared vars dict, control scripts, code templates

2026-06-10T04:14:20Z

- Named variables in expressions: source channel IDs injected as Python identifiers alongside x[] (e.g. write `A0 * 2` instead of `x[0] * 2`) - Shared `vars` dict on SignalProcessor accessible from all expressions, functions, and control scripts; persisted in .labdaq profiles - Per-derived-channel `state` dict for persistent computation state in custom scripts - Control widgets gain optional on_action_script (Python snippet with value, vars, channels, math in scope); syntax-checked in editor dialog - Built-in derived kinds (derivative, rms, power, etc.) now show their Python implementation as read-only code previews; "Edit as Custom Script" converts to custom_script kind with template pre-filled Co-Authored-By: Claude Sonnet 4.6

Channels/Signals UX: rename labels, calibration section, splitter, sig# IDs

2026-06-10T03:02:53Z

Naming conventions: - Devices window: "Channel ID" column → "Signal ID" - Serial device auto-gen IDs: CH# → sig# (generic, SCPI, Modbus fallbacks) - Channels window physical section: "Physical Channels" → "Signals" - Channels window virtual section: "Virtual Channels" → "Channels" - "Add Virtual" button → "Add Channel" - New derived channel default name: "Virtual Channel #" → "Channel #" Signals panel (ChannelPipelineBlock): - Remove Calibrate header button; add inline Calibration section in body - Remove Math section (Derivative/Integral) entirely - scale_offset excluded from filter dropdown; routed to Calibration section - Existing pipelines: scale_offset loads into Calibration, math filters dropped - _FILTER_KEYS excludes derivative, integral, scale_offset Splitter default position: - Left (Signals) pane initialised to minimum content width via QTimer.singleShot - setStretchFactor(0,0) / (1,1): left stays narrow, right grows on resize Co-Authored-By: Claude Sonnet 4.6

Changed dialog text window from channels to signals for clarity

Make Devices, Channels, Plot windows maximizable

2026-06-03T20:50:32Z

Remove Qt.WindowType.Tool flag — it suppresses the maximize button. Window now has standard chrome with minimize/maximize/close. Co-Authored-By: Claude Sonnet 4.6

Redesign Channels window: side-by-side layout, picker dialog, collapsible virtual blocks

2026-06-03T20:33:36Z

Physical channels panel: horizontal splitter (left/right), channel picker dialog replaces dropdown, Filters and Math sections per block, Calibrate button, pipeline-enabled checkbox removed. Virtual channels: collapsible blocks, enable checkbox removed, kind dropdown removed (defaults to expression). Window resized to 1400×820. Co-Authored-By: Claude Sonnet 4.6
