Output is not colored in an IDE (PyCharm) [Windows 8.1 / Python 3.4.3]

[wsw70]

I tried to reproduce the example script on Windows 8.1 (command prompt and PyCharm) but the output was not colorized.

As a side note, the example script provided in colorama works (the output is colorized, both in the command prompt and in PyCharm)

That is super weird, given that chromalog uses colorama, I see no obvious reason why the former doesn't work while the latter does.

Are you using the regular Windows command prompt or something like cygwin ? What is your Python version ?

When you mention the "example script", are you referring to the script that does that ?

import logging
import chromalog

chromalog.basicConfig(level=logging.DEBUG)
logger = logging.getLogger()

logger.debug("This is a debug message")
logger.info("This is an info message")
logger.warning("This is a warning message")
logger.error("This is an error message")
logger.critical("This is a critical message")

I used the cmd prompt as well as the built-in in the IDE (PyCharm). Both output non-colored output (and output colored one for colorama).

That's indeed the script I was using to test the functionality (it runs, outputs the expected lines but they are not colored)

@wsw70 Could you try:

python -c "from chromalog.log import ColorizingStreamHandler as CH; print CH().has_color_support"

In your terminal and give me the output ?

[wsw70]

I added parentheses for compatibility with Python3:

C:\Windows\System32>python -c "from chromalog.log import ColorizingStreamHandler as CH; print(CH().has_color_support)"
True

Ha. I just ran again the example script and

• it now works fine an a command line prompt (cmd)
• does not have a coloured output in an IDE (PyCharm in my case)

I am very sorry for the false alarm -- the new test was after several reboots so who knows what happened.

This said, the IDE output is still B/W, the colorama one outputs colors. Could that be that the environment is detected as being a non-tty one?

I will modify the title to reflect the reality of the problem.

[wsw70]

All is clear: the run environment of PyCharm is not detected as a tty:

import os, sys
print(
    os.isatty(sys.stdout.fileno()),
    sys.stdout.isatty()
)

(False, False)

Sorry again for the trouble, all is fine then. I will file a bug for PyCharm.

@wsw70 No problem !

Thanks for the follow up, I appreciate it.
