TAC Scripting Fully Enhanced

→ [Design] - [C applet]

Update function:

TAC Scripting has been fully enhanced to support efficient and concise manipulation of messages and signals, reading and writing system variables and arrays, embedding scripts in flowcharts, registering any parameter function as a global API, and responding to a variety of event sources such as timers, variable changes, message sending/receiving, and window lifecycle, which provides users with more flexible and powerful automation testing and verification capabilities.

• Message manipulation:TAC scripts now support reading, modifying, and sending CAN/LIN/FlexRay messages and their signals without having to manually parse the raw data;
• Variables read and write:Direct access/modification of system variables, support for arrays, structures; support for namespace writing a::b::c = arr;
• Flowchart inline:The TAC Flowchart program supports running TAC scripts directly in [string] or [file] mode for more flexible test logic;
• Advanced variable manipulation:Supports namespaces, array types, and statement inline writing, e.g. System::arr[2] = 3.14;
• Arbitrary parameter functions are registered as APIs:User-defined functions immediately become global APIs for other scripts or flowcharts to call;
• Triggered by multiple event sources:TAC functions can be triggered by timers, system variable changes, message sending and receiving, window events, and so on.
