nativelayout
Describe a screen in HTML-like text and get a native interface.
nativelayout is a declarative language for user interfaces.
You write a screen once, in a plain text file (.nl) that looks like HTML, and each programming language shows it with its own host. There is no WebView.
A .nl file has:
- HTML tags you already know (
div,p,button,input,img, ...); {values}that your code fills in;ifandforlines, for conditions and repetition;- a
<style>with simple CSS selectors.
The file only describes the screen. The logic (state and taps) stays in your own code, in a screen function.
nativelayout is a specification with implementations: Kotlin for Android, Python (this package) and JavaScript (used by the online editor). The same .nl file works unchanged in all of them.
This package is the Python implementation: a pure Python core (parser, expander, layout engine and differ) and a Kivy host that draws the screen.
Install
pip install nativelayout # core only, pure Python, no dependencies
pip install "nativelayout[kivy]" # core + Kivy host
Python 3.10 or newer. The host needs Kivy 2.x. On Android, package the app with buildozer (requirements = python3,kivy,nativelayout).
Example
screen.nl:
<nativelayout>
<style>
body { padding: 16px; gap: 12px; }
.mais { background-color: #2F81F7; color: white; border-radius: 20px; }
</style>
<body>
<h1>Hello, {name}</h1>
<p>Total: {n}</p>
<button class="mais">+ add</button>
</body>
</nativelayout>
main.py:
import kivy # noqa: F401
from nativelayout.core import state, view, click
from nativelayout.host import run_app, file_loader
def screen():
s = state({"n": 0, "name": "world"})
if click(".mais"):
s["n"] += 1
return view("screen.nl", s)
run_app(file_loader("."), app=screen)
The file describes the screen. The logic (state and taps) stays in your Python code, in a screen function.
What is in the package
nativelayout.core: parser, expander, layout engine, differ and the program side (state,view,click,go,value,save, ...). Pure Python.nativelayout.host: the Kivy host. It draws on a canvas; it does not build platform-native views.
nativelayout is a namespace package, so import from the two sub-packages: from nativelayout.core import state, view, click and from nativelayout.host import run_app, file_loader. The Kivy host is loaded only when you import nativelayout.host.
