Naïve EditBox implementations have `O(N)` complexity on single
character handling so no matter what you do it will be
ineffective. On each character pressed it rescans (word/line
breaking, etc.) of whole text.
That's why Sciter has three different text editors:
* `<textarea>` - standard for HTML multiline editor, ~1k chars.
* `<plaintext>` - Sciter specific multiline editor, 1mb chars.
Text is represented in paragraphs (DOM element holding text line)
so editing one paragraph is not causing re-layout of the whole.
* `<richtext>` - WYSIWYG editor that allow to edit HTML.
Sample of `<plaintext>` with support of colorizer/syntax
highlighting:
SDL, GLFW and Co. are mostly about basic window creation and
support of so called "message pumps"
This is basically what we do now. SDL creates windows, but
doesn't do much afterwards. I have high hopes about SLD3 though.
I would rather go with Skia from ground up. No SDL I mean. I've
convinced once SDL people to implement rich clipboard support
(they did in SDL3). Not just plain text but HTML, file lists,
images, etc. But drag-n-drop is still basic AFAIK.
It has:
* [Window
abstraction](https://github.com/google/skia/tree/main/tools/window) implementation. It is a bit simplistic but as a base for future expansions will work.
* GPU accelerated 2D graphics (DirectX, Metal, OpenGL, Vulkan).
*
[SkParagraph](https://github.com/google/skia/tree/main/modules/skparagraph) text container with styled text. A la `<p>` in HTML.
*
[SkPlainTextEditor](https://github.com/google/skia/tree/main/modules/skplaintexteditor)
The only problem with Skia is that its C++ interface is unstable,
so some isolation API layer is required in order to be used in D.
Essentially same thing as [Sciter/D
Graphics](https://gitlab.com/sciter-engine/sciter-js-sdk/-/tree/main/sciter%2B/D/sciter/graphics?ref_type=heads),
