exhello(3)

✨ exhello — bestie's first Allegro program ✨

okay so this is exhello, from the Allegro manual — the Allegro game programming library. she's a manual page, section 3, and she's literally the softest possible intro to graphics programming 🎀

🌸 NAME 🌸

exhello — a Simple graphical "hello world" program. part of the Allegro game programming library. yes bestie, graphical. not your terminal-print ass hello world. we're doing PIXELS 💅

🦋 SYNOPSIS 🦋

#include <allegro.h>

Example exhello

like. that's it. that's the whole thing. iconic behavior honestly ✨

💖 DESCRIPTION 💖

okay so listen. this is a very simple program — like, baby's first Allegro program — and what it does is show you how to get into graphics mode and draw text onto the screen. that's the whole vibe. no cap.

so you've got two big main character moments here:

• getting yourself into graphics mode 🖥️✨ (leaving the boring text-only world behind)
• drawing text onto the screen 🎀 (hello world but make it art)

and that's genuinely it. it's not doing anything fancy, and that's the point — it's the "hi bestie welcome to Allegro" moment. lowkey the most important example in the whole manual because it's where everybody starts 🫶
