couleur - ANSI terminal tool for python, colored shell and other handy fancy features

Couleur is a handy tool to play around with ANSI features in a unix terminal

installing

user@machine:~$ sudo pip install git+git://github.com/gabrielfalcao/couleur.git

features

• Single python file
• 100% tested
• comes with syntax sugar

nutshell

file-like objects filter

stdout filter

further

import sys, couleur

couleur.proxy(sys.stdout).enable()
print "#{bold}#{blue}#{on:black}This is#{normal} a test"
couleur.proxy(sys.stdout).ignore()

print "#{green}#{on:black}This is#{normal} a test"
couleur.proxy(sys.stdout).disable()

dynamic methods

couleur has a syntax sugar that is semantically nice:

print
import couleur
sh = couleur.Shell(indent=4)

sh.bold_black_on_white('Nice highlight\n')
# prints '\033[47m\033[1m\033[30mNice highlight\033[0m'

sh.indent()
# will increase a internal indentation factor in couleur.Shell instance

sh.red('Just red\n')
# prints indented as well '    \033[32mJust Green\033[0m\n'

sh.dedent()

# will decrease that indentation factor (above)

# syntax sugar
sh.green_and_normal_and_blue('this will be printed in green| and |this in blue\n')
# see: '\033[32mthis will be printed in green\033[0m and \033[34mthis in blue\033[0m'

couleur can overwrite output, so that you can make things like printing progress bars, show percentage and so on:

import time
import couleur

shell = couleur.Shell(linebreak=True, bold=True)

for num in range(101):
    if num == 0:
        print

    shell.yellow_and_red("Downloading file: |%d%%" % num, replace=True)
    time.sleep(0.02)

shell.white_and_green("Downloading file: |DONE!", replace=True)

Writing to other streams

Simply pass the output as first argument of the Shell

import couleur

with open('output.log', 'w') as output:
    shell = couleur.Shell(output, linebreak=True, bold=True)
    shell.white_and_green("done with | Some task")

furthermore

With couleur you can mix modifiers and colors.

Available modifiers:

• reset - resets from the current point to the end
• bold - make text bold
• blink - it may blink the text or make it slighly lighten, depending on the terminal
• italic - make text italic
• underline - add underline on text
• inverse - invert colors
• strikethrough - draws a line through the text
• up - does the same than passing replace=True to the output function: carriage return and one line up

Available colors:

• normal
• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white

Example chaining modifiers:

import couleur

shell = couleur.Shell(linebreak=True)
shell.bold_italic_underline_green_on_black_and_italic_black_on_white("WOO| HOO")
