Acquis 21 - String Interpolation

This manual page contains unstable information and its contents may change at any time.

String interpolation allows for the dynamic construction of strings by interpolating values into a template, which may be more intuitive than concatenation.

Syntax

Backticks are used to open and close interpolated strings.

print(`Hello, world!`)

Variables can be interpolated using the $name syntax, while expressions use the $(expr) syntax.

local x = "world"
print(`Hello, $x!`)
print(`The answer is $(10 + 20).`)

Interpolated strings can include newlines.

local x = "world"
print(`
Hello, $x!
The answer is $(10 + 20).
`)

Semantics

Values in interpolated strings are converted using the same mechanism as print and tostring. If you have a table with a __tostring metamethod, it will be invoked to retrieve the string representation of the table.
