A very thin Python package (mavenized for ImageJ2) to use the SciJava LogService as a handler for Python's logging facility. See the wiki page about Logging for more details about ImageJ's logging framework.
Developed and provided by the Imaging Core Facility (IMCF) of the Biozentrum, University of Basel, Switzerland.
The snippet below demonstrates how to use the handler in an ImageJ2 Python script utilizing the fabulous Script Parameters for retrieving the LogService instance.
#@ LogService sjlogservice
from sjlogging.logger import setup_scijava_logger
from sjlogging.setter import set_loglevel
def log_messages(level):
log.critical("+++ new round of messages (level %s) +++" % level)
set_loglevel(level)
log.debug('debug log message')
log.info('info log message')
log.warn('warn log message')
log.error('error log message')
log.critical('critical log message')
log.critical("--- finished round of messages (level %s) ---" % level)
log = setup_scijava_logger(sjlogservice)
log_messages('WARNING')
log_messages('INFO')
log_messages('DEBUG')
log_messages('WARNING')Running this code from ImageJ will result in the following messages being printed to the console or the Log window, depending on how you launch ImageJ:
