lite VS ewig

Another small, minimalist Lua-based text editor is Lite[1], and it's much less "light" cousin Lite-XL[2]

Playing with browser developer tools and always seeing obfuscated JavaScript makes me sad. I'm not a web developer, but I suspect the security gained is low enough to fall within the author's "unnecessary constraints."

On the other hand, there are projects like https://github.com/rxi/lite

Beyond the rendering which as noted is nothing that hasn't been done before (in general) the inherent OT/multi user + tree sitter functionality is something that entices me.

I'm surprised nobody pointed out lite/litexl here either it's rendering of ui is very similar (although fonts are via a texture; like a game would) and doesn't focus overly on the GPU but optimises those paths like games circa directx9/opengl 1.3

https://github.com/rxi/lite/blob/master/src/renderer.h

> is using pure software rendering (on top of SDL) in a rather naïve fashion

https://github.com/rxi/lite/blob/master/src/rencache.c#L4

I think you'll find that they found the naive approach was sufficiently poor, performance wise, that additional optimizations had to be applied on-top.

If you want to use it, use it. It's 'good enough'...

How about lite https://github.com/rxi/lite

You have options: - Sublime Text - VsCodium - Lite - https://github.com/rxi/lite

I like the single lapce.exe and loads reasonably fast.

But this is in a pre pre-alpha stage, so many bugs it's far too early for public feedback. It loads reasonably fast except chrome stats in top left then jerks towards the center. The start page says to bring up the command palette which I was unable to navigate via keyboard.

The open file dialog takes an eternity to load the first time, the path is in a text box that's not editable. Focusing a text file gives an Insert cursor which is in text mode, there's a noticable slow delay before writing the first character, text selection is non existent so lacks basic text editing features.

There is a built-in terminal however there's only a single tab.

The only thing that gives it potential is that the folder/file browsing is super quick even with a node_modules folder so it might be built on efficient rendering that can be improved.

Even for such a basic editor it's 38mb download. For a far smaller + more complete editor checkout Lite:

See the author instantly opening a ~1GB text file with async loading, paging through, copying/pasting, and undoing/redoing in their prototype “ewig” text editor about 27 minutes into their talk here:

It’s backed by a “vector of vectors” data structure called a relaxed radix balanced tree:

That original paper has seen lots of attention and attempts at performance improvements, such as:

Ewig is an interesting implementation using immutable data structures. https://github.com/arximboldi/ewig Very proof of concept, tries to be a little vi like. Might be worth checking out.

For another approach: I built a didactic text editor to teach "value oriented design" and immutable data-structures in C++:

It's design is covered in these talks:
