Bases: object

__init__(home_dir, logfname='Logger.log', loghead='', logmode='over')

close_log()

Fully stop logging and close log file.

In order to start logging again, a new logstart() call needs to be made, possibly (though not necessarily) with a new filename, mode and other options.

log(line_mod, line_ori)

Write the sources to a log.

Inputs:

• line_mod: possibly modified input, such as the transformations made by input prefilters or input handlers of various kinds. This should always be valid Python.

• line_ori: unmodified input line from the user. This is not necessarily valid Python.

log_write(data, kind='input')

Write data to the log file, if active

logstart(logfname=None, loghead=None, logmode=None, log_output=False, timestamp=False, log_raw_input=False)

Generate a new log-file with a default header.

Raises RuntimeError if the log has already been started

logstate()

Print a status message about the logger.

logstop()

Fully stop logging and close log file.

In order to start logging again, a new logstart() call needs to be made, possibly (though not necessarily) with a new filename, mode and other options.

switch_log(val)

Switch logging on/off. val should be ONLY a boolean.
