💅 CRYSTAL-PLAY(1) — the glow-up version

okay so this is a page from the Crystal Compiler Command Line Reference Guide, and it's literally just about one little command that spins up the Crystal playground for you. bestie, it's giving "one job, done cute" ✨

🌸 NAME 🌸

crystal-play — the lil' command that runs the Crystal playground 🎀

🦋 SYNOPSIS 🦋

crystal play [options] [file]

✨ DESCRIPTION ✨

So here's the vibe: crystal play starts the crystal playground server on port 8080, by default. That's it, that's the whole main character moment 💅 You run it, the server goes up, you go play. Iconic behaviour, no notes.

👑 OPTIONS 👑

  • -p PORT, --port PORT — this is where you tell the playground to run on the port you actually want. Default is 8080, so if you say nothing, it's 8080, periodt. 🍓
  • -b HOST, --binding HOST — binds the playground to the IP you name. so if you're being specific about where it lives, this is the flag for you 🫶
  • -v, --verbose — makes it show you detailed information about the executed code. no more mystery, we're getting the full receipts 🔥
fr fr, that's every option on the page — there are only three, and now you know all three. ate and left no crumbs 💀

💖 a lil sign-off 💖
