Parameters

Hidden parameters:

topic : string

The ros topic to listen on

fields : list:string_parameter

The Field in the topic to be logged. Syntax is comparable to ‘rostopic echo’: Lists with [], subitems with . (dot).

package : string

A rospackage in the workspace to place the file in. Leave empty if absolute path is wanted.

file_name : string

The name of the file to log the data into.

Accepts subsequent folders, “~” for home (if package==””) and the following special artefacts:

“{number}” -> starts at 0 and increases by one every time the logger is reentered within an application (e.g. application starts and stops logger in a loop);

“{timestamp%Y-%m-%d_%H-%M-%S}” -> Is replaced by the timestamp at starting with the given structure.

Examples: “{timestamp%Y-%m-%d}/{timestamp%H-%M-%S}_iteration_{number}.log” -> 2020-06-06/13-40-31_iteration_0.log

a : if file already exists, new data will be appended,
