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

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
