An evolution of the old WinForm text editor. After evaluating a lot of editors for my text editor project, I stuck with this old favorite. However it has a few deficiencies which I intend to correct.

• Dynamic loading of style/format files. Support user defined and editing.
• Rectangle region cut/copy/paste.
• Line wrap, or hover displays the whole line (like folded sections in VS).
• Add support for Lua.
• Maybe some performance tweaks.

Things I don't care about:

• WPF.
• .NET Core.
• Web apps, javascript...

The baseline is from ICSharpCode V3.2.1.7. Design notes from Core design.

After a long hiatus, another whack at this to go along with a slowly evolving editor project. The editor is more of text editor (for things like log files) rather than a code editor (because I have several other excellent choices there).

Things that have changed from the original (so far):

• Rectangle selection mostly works.
• Modernized HighlightingManager.
• Added printer support.
• Added finder class. Not fully functional yet and needs unit tests.
• Minimal Markdown syntax and folding. Good enough for what I want to do.
• Folding is now specified in the syntax file and loaded dynamically.
• Added Lua syntax.
• Dynamically load syntax definitions from file.
• Removed external dependencies so it can build.
• Upped to .NET 4.7.2, VS2019.
• Removed some hierarchy and abstraction. Because.
• Removed code tools, like completion etc.
• Removed/refactored lots more dodgy architecture.

Much refactoring and reorganizing later, I realize I need to do some major surgery, such as ripping out folding. I don't want to do that to this body so I'm taking the parts I want and moving them into a new project. This shall remain here, probably untouched for another five years.
