Taa-taa! Pyjamas now has a flexible logging module. I just pushed the code.
The pyjamas.logging module builds upon CPython's logging module. This means that the new module supports the whole features set of the Python logging module, as described in the Python module documentation [1]. The Pyjamas logging module provides 3 new handlers (as of today) to print out log messages: [1] http://docs.python.org/library/logging.html 1) AlertHandler ... show messages a window.popup() dialog 2) AppendHandler ... append messages to the end of document body 3) ConsoleHandler ... print messages using Firebug's console.log() function For your convenience the module provides 4 utility getters: - pyjamas.logging.getAlertLogger() - pyjamas.logging.getAppendLogger() - pyjamas.logging.getConsoleLogger() - pyjamas.logging.getPrintLogger() ... a logger printing to cerr (error output stream) Using the logging facility is easy, e.g. from pyjamas import logging log = logging.getPrintLogger() ... log.debug('This is a debug message') There are 5 log levels (DEBUG, INFO, WARNING, ERROR, CRITICAL) and their respective methods for logging a message (see [1] above). The default log level is set to DEBUG (I felt this helps avoiding misunderstandings), so "everything" you log is spit out. You can set the level to a higher value, e.g. logging.ERROR, to print out regular and critical errors only, at the same time leaving the log statements as they are in the code. I have replaced the print statements in doc/pyjs_site/website.py by logger calls, check out this example! TODO: * ConsoleHandler is not fully functional: The JS(...) function requires the argument being a string constant. Unfortunately the log messages aren't constant strings at compile time. This is the error message: [...] translator_proto.TranslationError: pyjamas.logging.handlers line 49: JS function only supports constant strings CallFunc(Name('JS'), [Mod(Const(" console.log('%s') "), Name('msg'))], None, None) Any ideas how to fix this?
