debug

Prints each message's payload to the console, to see what is flowing through a wire.

Properties

• full message — default off. When on, prints the whole message, with topic and any other fields the source adds, instead of only payload.

Wiring

Input — any message.

This node has no output.

Behavior

Each message prints one line: DEBUG node=ID payload=VALUE, or DEBUG node=ID msg=MESSAGE with full message on. The value is printed as Python shows it, so a string is in quotes: payload='hello'. Click the line in the console to find the node on the canvas.

The board prints the line, so the console shows it only while the editor is connected.
