EMILUA(3em)

💖 NAME 💖

okay so Emilua reference bestie, this is the EMILUA(3em) page, and Emilua - Lua execution engine is literally the name. That's the whole section — short, iconic, slay. 💅

✨ SYNOPSIS ✨

here's the exact call shape, no cap:

local fs = require "filesystem"
fs.copy_file(from: fs.path, to: fs.path[, on_existing: "skip"|"overwrite"|"update"]) -> boolean

🦋 DESCRIPTION 🦋

The description is giving “go read the C++ reference, bestie”: See https://en.cppreference.com/w/cpp/filesystem/copy_file. That's the whole official pointer — I'm not adding extra lore, fr fr.

🌸 on_existing 🌸

on_existing is the vibe check for when the file already exists. Behavior when the file already exists:

• nil — Report an error. 😭
• "skip" — Keep the existing file, without reporting an error. 🫶
• "overwrite" — Replace the existing file. 🔥
• "update" — Replace the existing file only if it is older than the file being copied. ⭐
