Rocs internally uses the QtScript Java Script engine. This means, all algorithms that you implement must use Java Script. In the following, we explain how to access and change elements of a graph document from the scripting engine. It is important to note that changes done by the scripting engine are directly reflected at the properties at the graph editor elements.
There are different execution modes for your algorithms:
Run: Execute the script until it finishes.
Stop: Stop script execution (only available while a script is executed).
During the execution of an algorithm, debug and program output is displayed in the Debug & Script Output. If the scripting engine detects a syntax error in your script, the error is also displayed as debug message. Note that all program messages are also displayed at the debug output (displayed as bold text).
You can control the text that is displayed at the script output by the following functions:
Console.log(string message); // displays the message as script output Console.debug(string message); // displays the message as debug output Console.error(string message); // displays the message as error output
The different parts of Rocs each provide a static element that can be accessed by the scripting engine. These are:
Documentfor the graph document
Consolefor the console log output
