Extended ROS logs for python (rospy)

extended_rospylogs implements for rospy some of the extra functionalities found in roscpp for logging.

Installation

You can install extended_rospylogs from pip using

pip install extended_rospylogs

or using

pip install git+https://github.com/charlielito/extended_rospylogs

ROS log messages extension

In rospy there are only 5 functions for logging: rospy.logdebug, rospy.loginfo, rospy.logwarn, rospy.logerr and rospy.logfatal. In roscpp you can find other options like ROS_DEBUG_COND, ROS_DEBUG_NAMED, ROS_DEBUG_COND_NAMED, etc (for more info go to ros logging).

The conditional option for logging is very useful when you want to have different logging messages in your nodes, and you want to change it in runtime (because you only can specify the log_level when initializing the node).

Extended Functions

For the moment here are implemented all the rospy logging functions with the cond option:

• logdebug_cond(bool, message)
• loginfo_cond(bool, message)
• logwarn_cond(bool, message)
• logerr_cond(bool, message)
• logfatal_cond(bool, message)

Usage

import rospy
from extended_rospylogs import logdebug_cond, loginfo_cond


rospy.init_node('some_node')
rate = 30
debug = True
r = rospy.Rate(rate)

while not rospy.is_shutdown():

  #### DO STUFF
  logdebug_cond(debug, "Some debug message")
  loginfo_cond(debug, "Some info message for debugging")

  r.sleep()

Note that the debug variable could be a node parameter so it could be changed on runtime.
