xnano is a python library that aims to provide a simple, complete and flexible
framework for building terminal applications. With xnano you can:
- Render textual, audio and visual content in your applications.
- Add interactive functionality that responds to users at runtime.
Quick Start
Every example below runs as written, and q quits it. The art and sound example
needs the audio extra (pip install "xnano[audio]"). The feature demo shows
most of what xnano can do: run it with python -m xnano (or xnano).
Put content on the screen
Write text, widgets and anything else onto a terminal and position it with numbers, percentages or words.
import xnano
from xnano.widgets import Gauge
with xnano.open(width=40, height=6) as terminal:
terminal.write(
'Hello, world!', x='center', border='rounded', padding={'horizontal': 2}
)
terminal.write(Gauge(0.6, label='60%'), y=4, width='100%')
terminal.run(quit_on='q')
Move things with formulas
A position from xnano.expressions is a formula that is evaluated again on
every frame.
import xnano
from xnano.expressions import ParentWidth, TimeElapsed, Width
with xnano.open(width=40, height=3) as terminal:
ball = terminal.write('●', y=1)
ball.x = (ParentWidth - Width) * (TimeElapsed % 2 / 2)
terminal.run(quit_on='q')
React with hooks
A hook runs a function when a key, the mouse, the clock or the state changes.
import xnano
with xnano.open(width=30, height=3) as terminal:
label = terminal.write('press space', x='center', y=1)
@terminal.hook(on='key', keys='space')
def pressed(context: xnano.Context) -> None:
label.text = f'space at {context.time.elapsed:.1f}s'
terminal.run(quit_on='q')
Add effects
xnano.effect builds a tachyonfx effect that animates how content looks.
import xnano
with xnano.open(width=40, height=5) as terminal:
title = terminal.write('xnano', x='center', y='center', border='rounded')
title.update(
xnano.effect('effect.fade_from', foreground='black', duration_milliseconds=1500)
)
terminal.run(quit_on='q')
Draw art and play sound
Pixel art is written as text, and notes and melodies play on the canvas. Sound
needs pip install "xnano[audio]".
import xnano
heart = xnano.draw(
"""
.RR.RR.
RRRRRRR
.RRRRR.
..RRR..
...R...
""",
'R=#e03040',
)
with xnano.open(width=20, height=5) as terminal:
terminal.write(heart, x='center')
terminal.write('♪ C4 E4 G4', x='center', y=4)
if terminal.audio.is_available:
terminal.play('C4 E4 G4:2', instrument='bell')
terminal.run(quit_on='q')
Install
You can install xnano with pip using your favorite package manager.
pip install xnano
To run untrusted or model-written Python against a canvas with xnano.monty,
add the monty extra: pip install "xnano[monty]".
xnano and its paired xnano-core dependency can be installed on Python 3.10+
on any of the following operating systems:
- Linux, x86_64 and aarch64: glibc distributions (
manylinuxwheels) and musl distributions such as Alpine (musllinuxwheels). Sound playback inxnano-audiouses the system ALSA library (libasound). Themusllinuxaudio wheels synthesize sound but cannot play it on a device. - macOS: x86_64 (Intel) and arm64 (Apple silicon).
- Windows: x86_64.
- WebAssembly (Pyodide): continuous integration
builds and tests only the
xnano-corewheel in Pyodide. The test imports its compiled modulexnano_core._xnano_coreand renders on a runtime without a screen. Thexnanopackage itself is not built or tested for Pyodide, andxnano-audioandxnano-imageare not built for WebAssembly.
On Linux, macOS and Windows every extension is an abi3 wheel, so one wheel per platform covers Python 3.10 and later.
Packages
xnano itself is built off of an ecosystem of several rust
(Pyo3) based packages that provide core and
multi-modal functionality to the library:
- xnano - The main
xnanopackage. - xnano-core - Python bindings for
xnanos's core ratatui based runtime. - xnano-audio - Audio playback & input support for
xnanowith the ability to compose audio content directly in python using MIDI patch instruments. (Built using []) - xnano-image - Image & animation loading/rendering
support for
xnanobuilt on ratatui-image. (Including native support for Kitty, iTerm2, Sixel and WebP images.)

Contributing
For information on how to contribute to xnano or any of its sub-packages
within this repository, please see Contributing to xnano.
This repository uses a UV &
Cargo workspace that can all be managed
through a set of make commands.
You can get started contributing to xnano by running the following commands:
git clone https://github.com/hsaeed3/xnano.git
cd xnano
make help
# Optionally install the development workspace.
# This first compiles all rust [crates](./crates/) and builds all python [packages](./packages/)
# for xnano's core extensions (xnano-core, xnano-audio, xnano-image).
# make install
