PyCharm logging output colours

I'm using PyCharm to develop a GAE app in Mac OS X. Is there any way to display colours in the run console of PyCharm?

I've set a handler to output colours in ansi format. Then, I've added the handler:

LOG = logging.getLogger()
LOG.setLevel(logging.DEBUG)
for handler in LOG.handlers:
    LOG.removeHandler(handler)

LOG.addHandler(ColorHandler())

LOG.info('hello!')
LOG.warning('hello!')
LOG.debug('hello!')
LOG.error('hello!')

But the colour is the same.

EDIT:

A response from JetBrains issue tracker: Change line 55 of the snippet from sys.stderr to sys.stdout. stderr stream is always colored with red color while stdout not.

Now colours are properly displayed.

Solution 1:

As of at least PyCharm 2017.2 you can do this by enabling:

Run | Edit Configurations... | Configuration | Emulate terminal in output console

Solution 2:

PyCharm doesn't support that feature natively, however you can download the Grep Console plugin and set the colors as you like.

Here's a screenshot: http://plugins.jetbrains.com/files/7125/screenshot_14104.png (link is dead)

I hope it helps somewhat :) although it doesn't provide fully colorized console, but it's a step towards it.

Solution 3:

Late to the party, but anyone else with this issue, here's the solution that worked for me:

import logging
import sys
logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)

This came from this answer

Solution 4:

Sept. 2019: PyCharm Community 2019.1

PyCharm colored all the logs including info/debug in red.

Th upshot is: it is not a PyCharm problem, this is how the default logging is configured. Everything written to sys.stderr is colored red by PyCharm. When using StreamHandler() without arguments, the default stream is sys.stderr.

For getting non-colored logs back, specify logging.StreamHandler(stream=sys.stdout) in basic config like this:

logging.basicConfig(
    level=logging.DEBUG,
    format='[%(levelname)8s]:  %(message)s',
    handlers=[
        logging.FileHandler(f'{os.path.basename(__file__)}.log'),
        logging.StreamHandler(sys.stdout),
    ])

or be more verbose:

logging.getLogger().addHandler(logging.StreamHandler(stream=sys.stdout))

This fixed my red PyCharm logs.

Solution 5:

What solved it for me (on PyCharm 2017.2) was going to Preferences -> Editor -> Color Scheme -> Console Colors and changing the color of Console -> Error output. Of course this also changes the error color but at least you don't see red all the time...
