Utilities for drawing and interactiveness at the terminal

Project description


This is a Python library allowing using a text-terminal as a low-resolution graphics output, along with keyboard realtime reading, and a couple utilities enough to enable using a text terminal to run simple 2D games or simply rich terminal apps.

The "noveau" factor is that it uses Unicode quarter-character block combinations to effectivelly enable 1/4 character "pixels" in the terminal. It also makes use of 24bit "true" color for text, not limiting itself to the 80's 8 color palette for the terminal.

The development version allows loading image files and displaying those as colored block chars on the terminal, several terminal-font text effects, and rendering big-text, 4 or 8 characters tall, by rendering built-in fonts as images using block characters.

It is designed as a library, providing a discoverable and easy to use API for drawing, and upon install a few example scripts will be imediately available as stand-alone scripts with the "terminedia-" prefix.

The idea is to keep this as a lightweight install - with as little dependencies as possible.


Although targeted for programatic use, after install a few example programs exercising the library capabilities are made available in the active Python environment. Try one of several "terminedia-xxxxx" scripts installed, such as "terminedia-image" and "terminedia-snake"

Some of the features are as easy to use as the print function from Python itself:

Other, like the drawing API which emulates pixels with unicode block characters require a couple more calls:

Check the in progress documentation at:

(nb. that documentation is currently for the 0.2 version, available from pypi. The project's capabilities evolved far beyond whats is in there, but docs are still missing - the "TODO.txt" file lists implemented features or fixes (marked with a "V") and a loose roadmap. Although for useage and documentation one has to rely on the doc-strings)

Also, the examples folder have concrete snippets and some stress-testing code. The examples were moved into the main package code, and granted stand-alone scripts status when the package is pip-installed.

After install, try calling any of the "terminedia-" scripts made available to check the output.

Although incipient in options, some of these example scripts can work as command line tools. For example terminedia-image <image_file> will downscale and display an image file in the terminal.

Note that the default pip install won't bring PIL, which results in limited image support - use pip install terminedia[images], or simply install PIL directly with pip install pillow, to be able to load arbitrary image files.


Preliminary Windows support - by using the Colorama Python package, with proper fonts configuration on the terminal, it is possible to experiment most of terminedia´s capabilities (the terminedia-snake example works). There is still work to be done, but for a better experience under Windows install the CMDER console emulator and the UNSCII fonts for rendering pseudographics (links in the file)

On Linux and other posix systems, Terminedia relies on ANSI scape sequences for all terminal manipulation. It should work in most Linux and Mac OS terminal applications (including non-X11, "native" terminals on Linux)

The output result will vary according to the terminal and font used - a nice experience can be achieved with the "Terminus" font, specially if one is using the Braille characters for drawing.

There is also an HTML backend that can output programatically created ASCII art to an HTML file, formatted with mono-spaced fonts inside a div element. The "terminedia-image" example program makes use of this feature.


Terminedia is licensed under GNU's LGPL 3.0 or later, meaning you are free to use it in whatver project you want, comercial or not, private or not - you are only required to contribute back any enhancements you make to this library itself. For details, please read acompanining "LICENSE" file.
