I need a TOML array. ·

rust

r/o

use std::error::Error;

use toml::{Value, map::Map};

fn usage() -> ! {

eprintln!("usage:");

eprintln!(" tomlarray KEY [STRING ...]");

eprintln!(" Dump a TOML array to stdout with the given key, containing the given strings.");

std::process::exit(1);

}

fn main() -> Result<(), Box<dyn Error>> {

let mut args = std::env::args_os().skip(1);

let Some(key) = args.next() else {

usage();

};

let key = key.into_string().expect("bad UTF-8 in input");

let values = args

.map(|a| a.into_string().expect("bad UTF-8 in input"))

.collect::<Vec<_>>();

let mut map = Map::new();

map.insert(

key.into(),

Value::Array(values.into_iter().map(|s| s.into()).collect()),

);

let table = Value::Table(map);

println!("{}", toml::to_string(&table)?);

Ok(())
