Package epydoc :: Module log

Module log

Functions used to report messages and progress updates to the user. These functions are delegated to zero or more registered Logger objects, which are responsible for actually presenting the information to the user. Different interfaces are free to create and register their own Loggers, allowing them to present this information in the manner that is best suited to each interface.

Note: I considered using the standard logging package to provide this functionality. However, I found that it would be too difficult to get that package to provide the behavior I want (esp. with respect to progress displays; but also with respect to message blocks).

Function Details

register_logger(logger)

source code

Register a logger. Each call to one of the logging functions defined by this module will be delegated to each registered logger.

start_block(header)

source code

Start a new message block. Any calls to info(), warning(), or error() that occur between a call to start_block and a corresponding call to end_block will be grouped together, and displayed with a common header. start_block can be called multiple times (to form nested blocks), but every call to start_block must be balanced by a call to end_block.

end_block()

source code

End a warning block. See start_block for details.

start_progress(header=None)

source code
call graph

Begin displaying progress for a new task. header is a description of the task for which progress is being reported. Each call to start_progress must be followed by a call to end_progress (with no intervening calls to start_progress).

end_progress()

source code
call graph

Finish off the display of progress for the current task. See start_progress for more information.

progress(percent, message=`''`)

source code
call graph

Update the progress display.

Parameters:

percent - A float from 0.0 to 1.0, indicating how much progress has been made.
message - A message indicating the most recent action that contributed towards that progress.
