This is an implementation of Rx text transformation script language.
Rx is a simple scripting language based on regular expressions designed to transform text information. The Ol.Text project is a Rx implementation for .NET Framework (>= 4.5), .NET Standard (>= 2.0) and .NET (>= 6.0) platforms.
This editor has some features from Notepad++, Sublime Text and Vim. The Typewriter.NET has no plugins, but has a simple way to run external scripts, navigate to output error and change text by external scripts. The main idea is make to possible work without mouse (and without arrows in vi-mode)
