EMILUA(3em)

💖 NAME 💖

Hiii bestie, welcome to the EMILUA(3em) page! This is all about Emilua — the Lua execution engine. Periodt. 👑

✨ SYNOPSIS ✨

format(fmt: string[, ...]) -> string

🦋 DESCRIPTION 🦋

Okay so format() takes your args and formats them according to the specifications in fmt, then returns the result as a string. It’s giving “build the perfect string” main character energy. 💅

Supported arguments:

• boolean
• number
• string

You may also specify pairs. First element must be a string and it works as a named argument. 🫶

The full specification for the format string can be found in the libfmt homepage: https://fmt.dev/latest/syntax.html.

🌸 Note: format() is a global so it doesn’t need to be require()d. No extra steps, bestie — it’s just there. ✨

🎀 EXAMPLE 🎀

format("{0}, {1}, {2}", 'a', 'b', 'c')
-- Result: "a, b, c"

format("{}, {}, {}", 'a', 'b', 'c')
-- Result: "a, b, c"

format("{2}, {1}, {0}", 'a', 'b', 'c')
-- Result: "c, b, a"

format("{0}{1}{0}", "abra", "cad") -- arguments' indices can be repeated
-- Result: "abracadabra"

format("{:.{}f}", 3.14, 1)
-- Result: "3.1"

format("Elapsed time: {s:.2f} seconds", {"s", 1.23})
-- Result: "Elapsed time: 1.23 seconds"
