A cross platform package to do curses-like operations, plus higher level APIs and widgets to create text UIs and ASCII art animations

Linux build status Windows build status Code Health Code Coverage Latest stable version Join the chat at https://gitter.im/asciimatics/Lobby


Asciimatics is a package to help people create full-screen text UIs (from interactive forms to ASCII animations) on any platform. It is licensed under the Apache Software Foundation License 2.0.


Why not? It brings a little joy to anyone who was programming in the 80s... Oh and it provides a single cross-platform Python class to do all the low-level console function you could ask for, including:

  • Coloured/styled text - including 256 colour terminals and unicode characters (even CJK languages)
  • Cursor positioning
  • Keyboard input (without blocking or echoing) including unicode support
  • Mouse input (terminal permitting)
  • Detecting and handling when the console resizes
  • Screen scraping

In addition, it provides some simple, high-level APIs to provide more complex features including:

  • Anti-aliased ASCII line-drawing
  • Image to ASCII conversion - including JPEG and GIF formats
  • Many animation effects - e.g. sprites, particle systems, banners, etc.
  • Various widgets for text UIs - e.g. buttons, text boxes, radio buttons, etc.

Currently this package has been proven to work on CentOS 6 & 7, Raspbian (i.e. Debian wheezy), Ubuntu 14.04, Windows 7, 8 & 10, OSX 10.11 and Android Marshmallow (courtesy of https://termux.com), though it should also work for any other platform that provides a working curses implementation.

It should be implementation agnostic and has been successfully tested on CPython and PyPy2.

(Please let me know if you successfully verified it on other platforms so that I can update this list).


Asciimatics supports Python versions 2 & 3. For the precise list of tested versions, refer to pypi.

To install asciimatics, simply install with pip as follows:

$ pip install asciimatics

This should install all your dependencies for you. If you don't use pip or it fails to install them, you can install the dependencies directly using the packages listed in requirements.txt. Additionally, Windows users (who aren't using pip) will need to install pywin32.

How to use it?

To use the low-level API, simply create a Screen and use it to print coloured text at any location, or get mouse/keyboard input. For example, here is a variant on the classic "hello world":

from random import randint
from asciimatics.screen import Screen

def demo(screen):
    while True:
        screen.print_at('Hello world!',
                        randint(0, screen.width), randint(0, screen.height),
                        colour=randint(0, screen.colours - 1),
                        bg=randint(0, screen.colours - 1))
        ev = screen.get_key()
        if ev in (ord('Q'), ord('q')):


That same code works on Windows, OSX and Linux and paves the way for all the higher level features. These still need the Screen, but now you also create a Scene using some Effects and then get the Screen to play it. For example, this code:

from asciimatics.effects import Cycle, Stars
from asciimatics.renderers import FigletText
from asciimatics.scene import Scene
from asciimatics.screen import Screen

def demo(screen):
    effects = [
            FigletText("ASCIIMATICS", font='big'),
            int(screen.height / 2 - 8)),
            FigletText("ROCKS!", font='big'),
            int(screen.height / 2 + 3)),
        Stars(screen, 200)
    screen.play([Scene(effects, 500)])


should produce something like this:


Or maybe you're looking to create a TUI? In which case this simple code will give you this:

    I'm using Mac OS X and when I press the "delete" key (in Macs this is deleting to the left, so actually backspace) in a Text widget, its size changes and starts to behave strangely.

  • Left/Right Navigation

    Left/Right Navigation

    It would be preferable for left and right to switch focus to the nearest widget rather than the bottom of the nearest widget's column. I have an app that is a grid of equal size buttons, which this behavior makes it unusable.

    Even if this is something you are not interested in doing. Can you point me in the right direction on getting this done per app? I subclassed Layout->process_event, I see the code for KEY_LEFT and KEY_RIGHT, but I am not understanding how it works. find_next_widget looks like where the magic happens. First value is the column difference. I would think start_at would be how far down the column to check for the next widget. That doesn't seem to be it tho. Even if it is, I'd need to get the row? somewhere.

  • text box with support for raw ansii input

    text box with support for raw ansii input

    For my app, I really needed to be able to support getting verbatim output from other terminal apps and showing it to the user. These other commands might print color text, and I wanted the color to be preserved and shown to the user as-is. I've basically been approaching my asciimatics app as if it were a web app in the terminal; if I were doing a web app, I would be able to use any HTML along with the framework widgets, and I had not considered that a similar way of working with asciimatics and raw ansii codes would be difficult.

    I dug around in the asciimatics code for a while and decided that implementing this as a widget would be... pretty difficult, at least for me. My workaround below might be useful for the library documentation.

    First we create a new exception to hold the external command to be run and scene to resume once it's finished:

    class ExternalCallException(Exception):
        def __init__(self, last_scene, command):
            self.last_scene = last_scene
            self.command = command

    When the external command should be run, we raise the exception like so (self is the widget object):

    raise ExternalCallException(self._scene, 'my command here')

    Then we add an extra except clause under the one handling screen resizes:

        except ResizeScreenError as e:
            last_scene = e.scene
        # new code below
        except ExternalCallException as e:
            last_scene = e.last_scene
                # -K means quit on ^C; -R means print ansii codes as-is
                process = Popen(e.command + " | less -K -R", shell=True)
            except KeyboardInterrupt:
                # let less handle this, -K will exit cleanly

    With this, the external command is piped to less, which temporarily controls the whole screen and shows the command's output in color. When the user quits less, the app reappears using the same mechanism as when the screen is resized.

  • Add support for scroll wheels

    Add support for scroll wheels

    As per our conversation 2022-02-06 at https://gitter.im/asciimatics/Lobby, I am requesting scrollwheel support in Asciimatics.

    Main technical thrust: Modify Screen to recognize scrollwheel events and handle it in the Frame

    I will begin work on this soon and submit a PR when I get it working.


    Jeff Wright @jeffwright13 Feb 06 06:35 @peterbrittain - is there a way to modify the scrolling behavior? When I use the scroll wheel on my mouse, it seems to want to scroll an entire page at a time, instead of what I have come to expect in a normal GUI: N lines at a time. The result is a very jumpy experience. I didn't see anything in the docs about configuring scroll behavior. peterbrittain @peterbrittain Feb 06 06:46 That's because asciimatics doesn't support scroll wheels (due to patchy support in Linux). I suspect what you're seeing is the terminal intercepting the event and scrolling the whole buffer. You'll be able to tell if this is the case, because asciimatics will still only draw on the original screen that was visible when you started the app. Jeff Wright @jeffwright13 Feb 06 06:55 So nothing to be done then? peterbrittain @peterbrittain Feb 06 07:08 Mouse support has improved in ncurses 6. Do you know what version your system uses? We'd also need to see if there is a setting on your terminal to force it to pass the input to the running app (instead of consuming it itself). Jeff Wright @jeffwright13 Feb 06 07:14

    I am running (currently) on a Macbook Pro (2019/Intel). Latest version of OSX. I usually run Pytest (and hence Asciimatics) out of iTerm2, although sometimes also from my IDE (VSCode, with Integrated Terminal). My shell is latest zsh.

    $ tic -V ncurses 5.7.20081102


    $ brew upgrade ncurses Running brew update --preinstall... ==> Auto-updated Homebrew! Updated 2 taps (homebrew/core and homebrew/cask). ==> Updated Formulae Updated 84 formulae. ==> Updated Casks Updated 36 casks.

    Warning: ncurses 6.3 already installed

    peterbrittain @peterbrittain Feb 06 08:02 Ok... with a newer version of ncurses, you then need to enable scroll wheel reporting. Looks like there's a setting in iterm2: https://iterm2.com/documentation-preferences-profiles-terminal.html Finally, we'd need to tweak asciimatics Screen to recognize the events and handle it in the Frame. All pretty self-contained changes, so I can explain them to you if you're up for submitting a PR. Jeff Wright @jeffwright13 Feb 06 09:16 Screen Shot 2022-02-06 at 9.16.13 AM.png Screen Shot 2022-02-06 at 9.16.38 AM.png Looks like I already had that setting enabled ("Enable mouse reporting") Sure, I could submit a PR. Would need some guidance on where in the code to make changes. peterbrittain @peterbrittain Feb 06 14:57 Ok... There are 2 basic changes. First is to _CursesScreen.get_event(). There's already logic to handle other buttons in there. We just need to find what events fire when you scroll the mouse wheel. You could either add some logging to the function, or use something like this: https://stackoverflow.com/questions/11893034/mouse-wheel-in-python-curses. According to the curses maintainer, it should look like mouse buttons 4 and 5. See https://stackoverflow.com/questions/42356352/mouse-scroll-up-ncurses-c Once you have those events translated into equivalent asciimatics MouseEvents, you just need to act on them in the scrollbar. That's in scrollbar.py. simply get the current position and add/subtract a percentage to the position on the relevant button. Jeff Wright @jeffwright13 Feb 06 20:54

    I made the following changes to screen.py.

                    # Some Linux modes only report clicks, so check for any
                    # button down or click events.
                    if (bstate & curses.BUTTON1_PRESSED != 0 or
                            bstate & curses.BUTTON1_CLICKED != 0):
                        buttons |= MouseEvent.LEFT_CLICK
                    if (bstate & curses.BUTTON3_PRESSED != 0 or
                            bstate & curses.BUTTON3_CLICKED != 0):
                        buttons |= MouseEvent.RIGHT_CLICK
                    if bstate & curses.BUTTON1_DOUBLE_CLICKED != 0:
                        buttons |= MouseEvent.DOUBLE_CLICK
                    if bstate & curses.BUTTON4_PRESSED != 0:
                    if bstate & curses.BUTTON5_PRESSED != 0:
                    if bstate & curses.BUTTON4_CLICKED != 0:
                    if bstate & curses.BUTTON5_CLICKED != 0:
                    return MouseEvent(x, y, buttons)

    This resulted in an exception when the scroll wheel was rolled:

    I am on a Mac. I saw the following comment in _curses.py:

    # Darwin ncurses doesn't provide BUTTON5_* constants

    Maybe that's the issue with the crash above. peterbrittain @peterbrittain Feb 07 00:58 Yeah - I wondered if we'd start hitting issue like this. We can create the constants ourselves if needed. For now, I suggest you just log the bstate in hex and compare it to https://github.com/mirror/ncurses/blob/d30f99439fcc8d4bb4c38e5c4afb4f6555fc6ad4/include/curses.tail Note that print doesn't work in alternate screens (like asciimatics uses). Also, if you don't like doing the bit maths, you can probably use this definition instead: https://github.com/mattn/pdcurses/blob/master/curses.h Jeff Wright @jeffwright13 Feb 07 11:14 The print was meant for initial diagnosis to see what button the system registered when I scrolled. Definitely will remove before issuing a PR! peterbrittain @peterbrittain Feb 07 11:57 :-)

  • Expanded Documentation and Examples for handling user input

    Expanded Documentation and Examples for handling user input

    Is your feature request related to a problem? Please describe. Full disclosure, I'm not a python power user, so I may well be missing something obvious with python itself.

    I'm building a video game, and have the engine mostly done in curses. I wanted to add fancy animations, so I started trying to port things over to asciimatics. However, I'm finding it hard to follow the docs in some places. For a specific example, I'm finding it hard to sort out how to use wait_for_input() in conjunction with get_event() as outlined in the docs, but there are no examples to pull from. It's not clear to me how I should even begin to get a user's input and then process it using these two methods.

    I can see the timeout of wait_for_input() is working in my script, but when I press any character the app just exits immediately. From the explanation in the docs, it made it seem as though I could just keep typing and the app would block execution until something is entered (presumably just hitting enter, but the docs aren't clear here either). I don't think this is a bug, but rather my misunderstanding of how it is supposed to function.

    The one example I've tried to follow that sort of has what I'm looking for is forms.py, but I don't see that there is any get_event() or wait_for_input() calls. None of the examples I've dug through seem to have these calls in them.

    Describe the solution you'd like Some example of using wait_for_input() and get_event(), and expand on the docs here: https://asciimatics.readthedocs.io/en/stable/io.html#input

    Would it be possible, at some point, to get an example that allows the user to input a word or short phrase in one frame, then display that entered text as FigletText in its own, separate frame?

    Additional context In my particular application, I've got several frames on-screen where one of those frames is a single-line input. Like a text adventure game, I want to have the user input a simple command then process it to change the db and then update the display with new info.

    I've been able to sort out a lot of other details from the docs, but the user input handling is one where I am a little lost. In curses, I was able to do what I needed to do with the textpad.Textbox object with relative ease. I thought that I might be able to use asciimatics's Text widget, but so far have been unsuccessful.


    I'm currently running python 3.10 with asciimatics v1.13.0, and I am being careful to dig through examples in the 1.13.0 tag.
