color formating of the output

[lorcat]

Hi! Many thanks for qtconsole. Myself and our users are using it almost every day.
There is one thing I would like to ask, maybe there is a way, but I could not find it in documentation.

I would like to have a control of custom color text output of the commands. If in linux terminal one could use special \e[1;31m
In qtconsole I do not see a simple way. Could someone guide me here?

Hey @lorcat, thanks for reporting. I don't understand what you mean by this

I would like to have a control of custom color text output of the commands

Could you post a screenshot to better understand your point?

This is how I understood the question:

In the terminal, one can use the special ANSI color codes (e.g. \e[1;31m) to set the current color of the text. You can use this to add colors to your text output. Does QtConsole support ANSI?

I think QtConsole does support ANSI codes to some degree. For example, this works:

print("\033[1;32;40m Bright Green  \n")

To work more easily with colors, python ships with the colorama module. Try this:

import colorama
from colorama import Fore
# strip=False disables some windows specific conversion that qtconsole doesn't support
colorama.init(strip=False)
print(Fore.GREEN + 'This text is in green')

Hi! Sorry for the late response. Yes, the question would be - is there a way to control color output of the text within the qtconsole similar to what is done in linux terminal.

I see that stuff output within logging.error() or warning is highlighted in red, info() comes in blue.

Can we control individual colors like here:

The output behavior in qtconsole depends on the selected syntax style. To ensure consistent parsing and formatting of output, you can generate output via the print function. For example, you can format your text with ANSI escape codes like this:
python:
print('\033[1;33m This is an example of green text.')

This method allows you to control the appearance of the text in the console.

Additionally, various PRs have been developed, for example to achieve the correct yellow color with ansi codes
