Replay plugin for MADS

This is a Source plugin for MADS.

This plugin allows to replay in MADS a CSV log file. It reads a CSV file and produces a JSON message for each line.

The CSV header line is interpreted as a list of keypaths. For example, if a column is /IMU/0/accel/x (notice the mandatory leading slash), the corresponding value gets into the JSON object {"IMU": [{"accel": {"x": 123.456}}]}.

An alternative keypaths syntax uses slashes as separators. For example, /IMU/0/accel/x can also be written as IMU[0].accel.x. Note that this sytax is less efficient and mostly supported for compatibility reasons.

A MADS message is emitted for each line, at a frequency set by the agent period (from command line -p or from INI file)

This plugin has been updated for MADS v2
