pyside6-scintilla 5.6.3.1

Permissively-licensed PySide6 bindings for the Scintilla code editor component

pyside6-scintilla

Permissively-licensed PySide6 bindings for the Scintilla code editor component.

Status

The ScintillaEditBase binding is implemented and working — see examples/simple_scintilla_base_edit/ for a runnable demo. Pre-built wheels are published on PyPI for Linux (x86_64), Windows (x86_64), and macOS (arm64, x86_64), Python 3.11-3.14 — see Installation. ScintillaEdit (Scintilla's full ~700-method API) and Linux aarch64 wheels are planned — see docs/mission.md for the roadmap.

Why this exists

The standard way to use Scintilla from Python + Qt is QScintilla (Riverbank Computing) — but it's a PyQt6 binding, with no PySide6 equivalent. Like PyQt6, it's also GPLv3 or commercially licensed.

Scintilla itself is licensed under the Historical Permission Notice and Disclaimer — a permissive license with no copyleft. This project aims to expose that permissive core directly to PySide6 users.

Goals

pyside6-scintilla aims to be:

• MIT licensed — usable in open-source or closed-source projects freely
• PySide6 native — built with shiboken6, integrating naturally with PySide6 widgets
• A faithful, low-level binding of Scintilla's ScintillaEditBase widget — not a reimplementation of QScintilla's higher-level API
• Available as pre-built wheels for Linux (x86_64, aarch64), Windows (x86_64), and macOS (arm64, x86_64)
• Not affiliated with Riverbank Computing or the QScintilla project

Installation

pip install pyside6-scintilla

PySide6 6.10+ is installed automatically as a dependency; the wheels bundle everything else ScintillaEditBase needs at runtime.

To build from source instead (e.g. for development), see docs/build.md for prerequisites (Qt 6.10+ with Qt6Core5Compat, a C++17 compiler) and platform-specific setup.

Usage

from PySide6.QtWidgets import QApplication
from pyside6_scintilla import Scintilla, ScintillaEditBase

app = QApplication([])
editor = ScintillaEditBase()
editor.sends(int(Scintilla.Message.SetText), 0, "hello, world")
editor.show()
app.exec()

ScintillaEditBase exposes Scintilla's low-level message API via .send()/ .sends() — the same SCI_* messages as the C interface, not a QScintilla-style high-level API. See examples/simple_scintilla_base_edit/ for a complete example (line-number margin, block selection/editing).

Versioning

Version numbers follow <Scintilla version>.<binding revision> — e.g. 5.6.3.0 is binding revision 0 for Scintilla 5.6.3. The binding revision increments for releases of this package that don't correspond to a new Scintilla version (bug fixes, new API surface, CI changes, etc.), and resets to 0 when Scintilla itself releases a new version.
