- Odin version: dev-2025-10-nightly

- SDL3

## Roadmap

- [x] Migrate from SDL2 to SDL3

- [x] Render/draw only visible lines

- [x] Scrolling

- [x] Cursor

- [x] Delete text

- [x] Status line for vim mode (NORMAL, VISUAL, INSERT)

- [x] Add an FPS cap

- [ ] Open and read files (partially done; currently no ability to open a file while running the program)

- [ ] Use command line to edit editor appearance (font, font size, colors, etc) and to open new files

- [ ] Color code block comment (`/**/`)

- [x] Jump to line

- [ ] Search in file

- [ ] Copy/Paste

- [ ] Highlight text

- [ ] Save/Save as

- [ ] Vim motions (a, w, b, ciw, viw, dd, gg, ^, %, etc)

- [ ] Show current file name

- [ ] Mouse support (maybe? Who uses a mouse?)

- [ ] LSP support

- [ ] Indenting (probably with LSP support?)``

- [ ] Look into 'Gap buffer' & 'Rope (data strucutre)' to work with text, because storing text as char array is expensive

# Running on Linux

- Install SDL3 core and SDL ttf (instructions are provided by SDL under SDL repo)

    - `error while loading shared libraries: libSDL3.so.0: cannot open shared object file: No such file or directory`

       to solve it, run `sudo ldconfig`

## Known errors/bugs

- On linux, when using `picom` there might be some flickering (not sure why atm).

  I was using CPU on Powersave mode and the frames dropped quite low at times,

  but on performance mode they still seem too low on my desktop vs on my laptop.

  Desktop gets slightly over 100, but laptop goes to ~300 without the cap.

  Desktop has i5, laptop has i7
