In JavaScript the de-facto standard library for the task is chalk, and after using it for a while in JS projects, the solutions available in the Python world were lacking in comparison. This allows the library to take care of all edge cases by inserting the "spurious" ANSI escape codes where needed. Therefore if compatibility with many terminals is a goal, it's best to use a high-level library that offers automatic handling of style resets. The issue will only be reported later by others or cause problems e.g. If a developer's local terminal doesn't have these quirks, the developer will not discover these quirks immediately. Also, some terminal have problems with simply overriding mutually exclusive styles, and require inserting "unnecessary" reset codes. fails to get edge cases right: For instance in some terminals it is necessary to reset styles before newlines, and re-activate them after the line break.more error prone, because you can accidentally forget to reset a style,.more verbose syntactically, because resets have to be specified explicitly,.These approaches have subtle issues: Inserting on/off styles manually is
DWARF FORTRESS WIKI HOW TO
Many answers to this question demonstrate how to ANSI escape codes directly, or suggest low-level libraries that require manual style enabling/disabling. High-level libraries vs low-level libraries / manual style handling? Here are some design decision you may consider for choosing your solution. It is one of the few libraries that properly supports nested styles:Īpart from that yachalk is auto-complete-friendly, has 256/truecolor support, comes with terminal-capability detection, and is fully typed. Here is my modern (2021) solution: yachalk
DWARF FORTRESS WIKI INSTALL
It's also worth noting that this is cross platform and has been tested on Mac, Linux, and Windows.Ĭolorit is now available to be installed with PyPi! You can install it with pip install color-it on Windows and pip3 install color-it on macOS and Linux. # If you are using Windows Command Line, this is so that it doesn't close immediately Print(background("This color has a custom grey background", (150, 150, 150)))Ĭolor("This text is blue with a white background", Colors.blue), Colors.white Print(color("This color has a custom grey text color", (150, 150, 150))) Print(background("This text has a background that is white", Colors.white)) Print(background("This text has a background that is purple", Colors.purple)) Print(background("This text has a background that is blue", Colors.blue)) Print(background("This text has a background that is green", een)) Print(background("This text has a background that is yellow", Colors.yellow)) Print(background("This text has a background that is orange", Colors.orange))
Print(background("This text has a background that is red", Colors.red)) Print(color("This text is white", Colors.white)) Print(color("This text is purple", Colors.purple)) Print(color("This text is blue", Colors.blue)) Print(color("This text is yellow", Colors.yellow)) Print(color("This text is orange", Colors.orange)) Print(color("This text is red", Colors.red)) # Use this to ensure that ColorIt will be usable by certain command line interfaces Here are some examples: from colorit import *
DWARF FORTRESS WIKI CODE
To use code like this, you can do something like: print(bcolors.WARNING + "Warning: No active frommets remain. For a simple example, here's some Python code from the Blender build scripts: class bcolors: The most common way to do this is by printing ANSI escape sequences. This somewhat depends on what platform you are on.
