Overview
SyntaxEditor is a powerful text editing control that is packed with features for efficient code editing, including syntax highlighting, code outlining, parsing, line numbers, block selection, IntelliPrompt UI, split views, adornments, bi-directional support, and much more. It has many of the same code editing features found in the Visual Studio code editor.

SyntaxEditor is built on top of our next-generation extensible text/parsing framework. While over 20 sample languages are available to get you started (such as C#, VB, XML, and more), custom language definitions can be developed and distributed with your applications as well. SyntaxEditor is designed for use in IDE (integrated development environment) applications, however there are many other applications out there than can take advantage of such a control.

- Free sample language definitions for common languages like Assembly, Batch files, C, C#, C++, CSS, HTML, INI files, Java, JavaScript, Lua, Markdown, MSIL, Pascal, Perl, PHP, PowerShell, Python, RTF, Ruby, SQL, VB.NET, VBScript, and XML.
- Lexing of text into tokens, via a "dynamic" regex pattern-based lexer, "programmatic" hand-coded lexers, or other custom options.
- Multi-threaded parsing capabilities.
- Code fragment editing with full IntelliPrompt, such as editing a method body, when using advanced languages.
- Categorization of text ranges into classifications (used to drive features like syntax highlighting).
