Color printing in python

Project description

CircleCI

codecov

A Light-weight python package for terminal output in color

Overview

Chalk allows you to print to your terminal in color. It also provides a simple logging handler and formatter for a more informative logging experience. Why print in black and white?

Installation

pip install pychalk

Usage

from __future__ import print_function
import chalk

print(chalk.red('foo'))
import chalk

white = chalk.Chalk('white')
white('foo', bold=True, underline=True)
# returns '\x1b[37;1;4mfoo\x1b[0m'

bold_white = white + chalk.utils.FontFormat('bold')
bold_white('foo')
# returns '\x1b[37;1mfoo\x1b[0m'

bold_white + 'foo'
# returns '\x1b[37;1mfoo'

bold_white + 'foo' + chalk.RESET
# returns '\x1b[37;1mfoo/x1b[0m'

Using Docker

Alternatively use a docker image with pyenv installed. This project uses anthonyalmarza/alpine-pyenv:cable which has pyenv setup with the latest versions of python 2.7, 3.5 and 3.6 (as of Dec 19th 2017).

First build the image and tag it as chalk

./bin/local/build

Then run the tests

./bin/local/test
