Intro

What is it?

A terminal string styling library for python. It implements a subset of Sindre Sorhus' chalk (which is for js).

e.g. chalk.green.bold("success") prints like you'd expect in the console.

Why create it?

I am familiar with and enjoy the syntax of chalk. Anthonyalmarza's chalk deviates from that syntax and so I created my own.

I'm also new to python so this was a good way to learn.

Why the subset of features?

I only use chalk for very simple purposes so I left out things like 256 colors.

Install

$ pip install simple_chalk

Usage

from simple_chalk import chalk, green

# both of these are the same
print(chalk.green("success"))
print(green("success"))

# chained
print(green.bold("success"))

# assign combinations
success = green.bold.underline
print(success("we did it!"))

# last color wins
print(green.red("this is red"))

# background and foreground colors are separate
whyNot = green.bgWhite.red.bgGray
print(whyNot("this is red text with a gray background"))

Api

simple_chalk exports the following

chalk (string) => string

• A singleton that can be used instead of importing the colors and styles directly.
• chalk and all exported colors/styles are chainable callables. When called, they take a single string argument and return a string wrapped in the appropriate ascii color codes.

newChalk () => Chalk

• You probably don't need this, but it creates a new chalk instance in case another library is misbehaving.

The following colors are exported

• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white
• blackBright (also 'gray' and 'grey')
• redBright
• greenBright
• yellowBright
• blueBright
• magentaBright
• cyanBright
• whiteBright

Each color also has a camel-cased bg equivalent. e.g. bgBlack and bgYellowBright

Finally the following miscellaneous styles are exported

• bold
• dim
• underline
• hidden

Test

hub clone olsonpm/py_simple-chalk
cd py_simple-chalk
python runTests.py

Features included from js version of Chalk

• chainable api
• same color names (with added aliases)

Features omitted

** Features marked with * are ones I'd pull in should someone create a PR.

• 256 colors and TrueColor support
• multiple arguments, and thus nested styles
• *color support detection
• *blue -> blueBright auto conversion on windows
• *ability to disable
• *modifiers other than the miscellaneous styles noted above. e.g. reset, italic, inverse etc.
