ANSI escape code library for Python

Pansi is a clean and simple ANSI escape code library for Python.

General usage

Pansi provides an object called ansi through which all escape codes can be selected. This object exposes the codes as both attributes (e.g. ansi.red) and items (e.g. ansi["red"]).

This object can therefore be used in several different ways, but the simplest is through the string format method. Here, if the object is supplied as a simple named argument, all references need to be prefixed:

Alternatively, passing the object with the ** operator removes the need for prefixes and thus makes the template string shorter. However, this does introduce a greater chance of clashing with other parameters, and doesn’t signal which parameters are which.

Ultimately, it is a subjective choice between these two options.

Colours

For foreground text, the standard set of colours can be selected using the lower case name for normal brightness and the upper case name for high intensity. To select as the background colour instead, simply prefix with bg., e.g. bg.blue.

Colour	Foreground	Background
Black	black	bg.black
Red	red	bg.red
Green	green	bg.green
Yellow	yellow	bg.yellow
Blue	blue	bg.yellow
Magenta	magenta	bg.magenta
Cyan	cyan	bg.cyan
White	white	bg.white
Bright black	BLACK	bg.BLACK
Bright red	RED	bg.RED
Bright green	GREEN	bg.GREEN
Bright yellow	YELLOW	bg.YELLOW
Bright blue	BLUE	bg.YELLOW
Bright magenta	MAGENTA	bg.MAGENTA
Bright cyan	CYAN	bg.CYAN
Bright white	WHITE	bg.WHITE

Full 24-bit colour support is also available (on those terminals that support it) by using the rgb selector.

Foreground and background colours can be inverted and then set back to normal using the rev and _rev tags respectively.

To reset foreground and background back to their defaults, use fg.reset and bg.reset.
