V-term

A terminal emulator with support for VGA graphics (see gfx modes below).

Building

cd build
cmake ..
make vterm

This is a personal project and work in progress (see TODO below)

TODO

• pty modes
  • Ensure the text conforms to resolution (+ mod window size)
  • Scrolling
  • Wrapping
  • Escape codes (See here and here)
    • Colors
      • 3 bit
      • 8 bit
      • Full color
• gfx modes (see here)
  • shared process memory (shm_open or mmap) for vram (aka vram store in ram)
• General (done using custom escape codes)
  • Switching modes (discarding all elements in current buffer)
  • Switching buffers (change current_buffer)
• Other todos for future
  • Improve performance
    • Call DrawText once per frame (custom DrawText function to account for color both bg and fg)
      • Did not improve performance significantly... instead generate one texture with all the text per frame?
    • For background colors, having many on screen makes it unperformant, fix this.
    • Multithreading ?
