Permissively-licensed Python bindings for the Scintilla code editor component and its lexer library, Lexilla.

The packages

Two packages, built in one repo and released to PyPI separately:

Package	PyPI	What it is
pyside6-scintilla		The Scintilla editor widget for PySide6 -- a GPL-free alternative to PyQt6-QScintilla.
lexilla		Lexilla's lexers (syntax highlighting and folding for ~125 languages), handed to a pyside6-scintilla editor.

pip install pyside6-scintilla lexilla

from PySide6.QtWidgets import QApplication
from lexilla import Language, create_lexer
from lexilla.pyside6_scintilla import set_lexer
from pyside6_scintilla import ScintillaEdit

app = QApplication([])
editor = ScintillaEdit()
lexer = create_lexer(Language.CPP)
assert lexer is not None
set_lexer(editor, lexer)
editor.setText("int main() { return 0; }")
editor.show()
app.exec()

Each package's page has the details; the examples gallery has complete apps, and Reference the Python API.

Why this exists

The usual way to use Scintilla from Python with Qt is QScintilla -- a PyQt6 binding, GPLv3 or commercially licensed. Scintilla and Lexilla themselves are permissively licensed (HPND). These packages expose them directly to PySide6 users under MIT -- see the mission for the full background, and How the packages are built for why they're two packages with two different binding stacks.
