It currently consists of the main code editor subclassing from QPlainTextEdit with a side widget for line counter. It currently supports syntax highlighting for .json and .py files, they are QSyntaxHighlighter class which can be found in the highlighter folder.

Getting Started

Prerequisites

• Qt: a module that supports different python qt bindings

  or alternatively, change the code below to whatever qt binding you have on your machine.

  from Qt import QtWidgets, QtCore, QtGui
  from Qt import _loadUi

Launch

1. Unzip the qt-code-editor package and run main.py directly

2. Or include the following snippet to your ui code to create a code editor with syntax highlighting.

   import codeEditor
   from highlighter.pyHighlight import PythonHighlighter
   
   editor = codeEditor.CodeEditor()
   highlighter = PythonHighlighter(editor.document())

Note: if you are using highlighter in a UI class, you'll need to keep an instance of the highlighter object like so:

self.__highlighter = PythonHighlighter(editor.document())
