ZLTT (Zig Lua TUI Tool) is a simple toy project to create a simple TUI (Text User Interface). Think of emacs TUI but you don't need 10 years to learn it! 😅

Programs for zltt are written in Lua and zltt uses Zig and SDL to render a GUI.

The Lua API is extremly simple but very versatile. Look at lua/examples/ for example functionality.

Zig SDL2 LuaJIT fontconfig

To build run zig build

To run an example do ./zig-out/bin/zltt lua/examples/todo/init.lua

putMainText(text)

This function prints text to the main screen

putSubText(text)

This function prints text to the bottom line of the screen

handleInputEvent(key)

This function is called when on a KEYDOWN event. The value of key is the ascii integer of the charater. To recover the character in lua use string.char(key)
