QRegexEditor

About

QRegexEditor is a simple regular expression editor written in Python and PyQt.

You can use QRegexEditor as a standalone application but also as a widget in your own PyQt/PySide application.

The tool has been inspired by:

• rubular: http://rubular.com/
• pythex: https://pythex.org/

Installation

First install the package from pypi::

pip install qregexeditor --upgrade

Then you can run the application::

QRegexEditor

Dependencies

• python (2.7 or >= 3.2)
• PyQt5 or PySide or PyQt4

Using the widget in a custom PyQt application

Use the widget as any other qt widget.

You may specify the regular expression and the string pattern programmatically. You might also want to connect to the quick_ref_requested signal so that your application can show/hide a quick reference widget in the most appropriate place.
