## Status

See [GitHub Issues](https://github.com/borco/pyside6-scintilla/issues) for
what's done and what's next.

## Why this exists

The standard way to use Scintilla from Python + Qt is
[QScintilla](https://riverbankcomputing.com/software/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](https://www.scintilla.org/License.txt) —
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

<!-- sync:installation -->
Install from [PyPI](https://pypi.org/project/pyside6-scintilla/):

```bash
pip install pyside6-scintilla
```

`PySide6-Essentials` 6.10+ is installed automatically as a dependency; the
wheels bundle everything else `ScintillaEditBase` needs at runtime. Essentials
provides the whole `PySide6` import namespace — only `QtCore`, `QtGui` and
`QtWidgets` are used here, so the ~175 MB of `PySide6-Addons` (Qt WebEngine,
Qt3D, QtCharts …) is left out. Install `PySide6` yourself if you want them.
<!-- /sync:installation -->

To build from source instead (e.g. for development), see
[docs/build.md](https://github.com/borco/pyside6-scintilla/blob/master/docs/build.md)
for prerequisites (Qt 6.10+ with `Qt6Core5Compat`, a C++17 compiler) and
platform-specific setup.

`examples/highlighting/lexilla_highlighting/` uses
[lexilla](https://pypi.org/project/lexilla/) as a dev dependency, installed
from PyPI like any other package.

## Usage

<!-- sync:usage-example -->
```python
from PySide6.QtWidgets import QApplication
from pyside6_scintilla import ScintillaEdit

app = QApplication([])
editor = ScintillaEdit()
editor.setText("hello, world")
editor.show()
app.exec()
```
<!-- /sync:usage-example -->

`ScintillaEdit` exposes a typed method per Scintilla message (e.g.
`setText()`, `textLength()`, `gotoLine()`) on top of `ScintillaEditBase`'s
raw `.send()`/`.sends()` message API — the same `SCI_*` messages as the C
interface, not a QScintilla-style high-level API. See
[examples/simple_scintilla_edit/](https://github.com/borco/pyside6-scintilla/tree/master/examples/simple_scintilla_edit/)
for a complete example (line-number margin, "Go to Line", block
selection/editing), or
[examples/simple_scintilla_base_edit/](https://github.com/borco/pyside6-scintilla/tree/master/examples/simple_scintilla_base_edit/)
for the lower-level `send`/`sends` API.

## 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.
