A Lightweight Qt-based code and text editor

QTextPad is designed to be a simple, lightweight text editor that works seamlessly and simply across several desktop platforms.

It was created out of a desire to have a fast and light editor like the excellent Notepad2, but with support for other platforms like Linux and macOS, and for a much larger range of file formats. To that end, QTextPad uses the same Syntax Highlighting library that powers Kate, giving it access to the same (ever growing) repository of file formats that Kate supports.

• Supported on Windows, Linux, macOS
• Syntax highlighting support for hundreds of file types and dialects.
  • (Optional) online update of file type support, directly from Kate's repository.
• Support for reading and writing many common text encodings.
• Fast, lightweight design -- no plugins, session management, etc. to deal with when you just want to open a file.
• Attractive design with Light or Dark Theme.
• Many helpful code editing features inspired by other popular editors like Notepad2, Kate, gedit...
