robots.helpers package

robots.helpers.ansistrm module

An ANSI-based colored console log handler, based on https://gist.github.com/758430, and with a few special features to make sure it works well in pyRobots’ concurrent environment.

class robots.helpers.ansistrm.ConcurrentColorizingStreamHandler(scheme=None)

Bases: logging.StreamHandler

A log handler that:

• (tries to) guarantee strong thread-safety: the threads generating log message can be interrupted at any time without causing dead-locks (which is not the case with a regular StreamHandler: the calling thread may be interrupted while it owns a lock on stdout)
• propagate pyRobots signals (ActionCancelled, ActionPaused)
• colors the output (nice!)

color_map = {'blue': 4, 'black': 0, 'yellow': 3, 'cyan': 6, 'green': 2, 'magenta': 5, 'white': 7, 'red': 1}

emit(record)

format(record)

handle(record)

Override the default handle method to remove locking, because Python logging, while thread-safe according to the doc, does not play well with us raising signals (ie exception) at anytime (including while the logging system is locking the output stream).
