Simple interface for printing colored text to a terminal
Simple Python interface for printing colored text to a terminal.
For the time being, both Python 3 and Python 2.7 are supported. However, only Python 3 support is guaranteed for the future. But since this library probably won’t have many reasons to change, it’s likely that Python 2.7 will be supported for awhile.
Install from PyPi:
pip install echocolor
To install for development, clone this repo, then cd into the directory and do pip install -e .[dev]
Without the dev dependencies:
python -m unittest discover tests/
Or in a dev environment to include test coverage:
pip install nose coverage nosetests --nocapture --with-coverage --cover-erase --cover-package echocolor --cover-inclusive tests/
Basic usage would would involve echo and err, which write to stdout and stderr respectively. The methods available on them are dynamically defined from a list of colors (see full list at the end of readme). echo and err provide methods for normal foreground and background coloring. The structure of the method names is echo.<color> for foreground colors, and echo.<color>_on_<bgcolor> for foreground on background colors.
from echocolor import echo, err echo.cyan("This text will be cyan") echo.magenta_on_yellow("This text will be magenta with a yellow background and will look terrible") err.light_red("This text will be red and written to stderr instead of stdout")
In addition to colors, bold and underlined text are also possible:
echo.bold("This text will be bold") echo.underline("And this will be underlined")
If you want to color strings without printing them, import colors:
from echocolor import echo from echocolor.colors import light_green green_text = light_green("This part will be green") print("This part will be regular. " + green_text)
However, since the strings end with the escape code to reset all styling, doing something like the following will result in the second part of the line being unstyled:
from echocolor import echo from echocolor.colors import magenta echo.underline(magenta("This text will be magenta and underlined.") + " But this text will be unstyled.")
By default, if stdout is being redirected then all the echo output will be unformatted. That can be changed by setting echo.force_color = True.
The following colors are supported along with any combination of <colorX>_on_<colorY>. The full list can also be seen from the code by checking the value of echocolor.terminal_codes.COLORS.
black red green yellow blue magenta cyan light_gray dark_gray light_red light_green light_yellow light_blue light_magenta light_cyan white
