use fish_printf::{sprintf_locale, ToArg, FormatString, locale};
use std::fmt::Write;

let mut output = String::new();
let fmt: &str = "%'0.2f";
let mut args = [1234567.89.to_arg()];

let result = sprintf_locale(&mut output, fmt, &locale::EN_US_LOCALE, &mut args);

assert!(result == Ok(12));
assert_eq!(output, "1,234,567.89");
