pyqcodeeditor 0.3.7

A qtpy implementation of Megaxela’s QCodeEditor (based on C++ Qt).

PyQCodeEditor

A simple code edit widget for pyside and pyqt (qtpy).

Description

This is a python implementation of the QCodeEditor（written in C++ Qt）. This project uses qtpy as the abstract layer of different python bindings of Qt, so that the user can choose whatever python binding of qt they want, like pyqt5、pyqt6、pyside2、pyside6.

The original QCodeEditor can be found here: https://github.com/Megaxela/QCodeEditor.

Status

Now the following features are implemented:

1. Auto parentheses.
2. Different highlight rules.
3. Auto indentation.
4. Replace tabs with spaces.
5. Some builtin completion and highlight rules
6. Support custom themes and styles
7. Pure python, No C++ code

Completers for:

1. C++
2. Python
3. Lua
4. glsl

Highlighters for:

1. C++
2. Python
3. Json
4. Lua
5. glsl

Unimplemented and known bugs:

• Frame selection (I write the python according to the original C++ code, but some bugs are occurred and I don't know why and how fix it for now)

• Highlighting for python's multi-line strings is not fully behave as expected (again I don't time to look into it and find a workaround now, any help is welcome)

Different from QCodeEditor:

• The styles and language rules are defined in json instead of xml

Note: This is not a fully featured IDE or code editor like VS Code

Get-Started

Install this library

pip install PyQCodeEditor

Install the python binding of QT you want, for example, PySide2

pip install pyside2

Import QCodeEditor and use it as any regular qt widget:

from qtpy.QtWidgets import QApplication
from pyqcodeeditor.QCodeEditor import QCodeEditor
from pyqcodeeditor.highlighters import QPythonHighlighter
from pyqcodeeditor.completers import QPythonCompleter

app = QApplication([])
editor = QCodeEditor()
editor.setCompleter(QPythonCompleter())
editor.setHighlighter(QPythonHighlighter())
editor.resize(800, 600)
editor.setPlainText("print('hello world!')")
editor.show()
app.exec_()

Here is a screenshot of the above code:
