Yes, Scintilla is a text editor engine library. It's not tied to any particular UI or technology. Out of the box it's not a text editor yet; you provide the frontend. You get all the "table stakes" right away if you build your editor on this library.

Here's Scintilla driving a TUI text editor: https://github.com/magiblot/turbo

Here's Scintilla driving a custom GUI control (not the system text control): https://github.com/desjarlais/Scintilla.NET

Same engine, different frontends. The engine has a series of hooks that you implement in whichever way you please for your particular interface. It's definitely the presumptive choice here.

Ah, I see! Very cool! Yeah, this is the kind of thing I was looking for, so this should give me what I need to test some proof of concepts. Thanks for the links! I do wish there were something a little more ergonomic, but I'm way too far into the begging to be choosing, here, so I'm quite happy to take what I can get.

In any case, I really do appreciate the dual links. It's so much harder to suss out the boundaries of a library with only one implementation. This was really helpful.
