Multi-line k/v pairs

[rakanalh]

Hello,

If i have:

[keys]
key1 = {
    use = true,
    value = "123"
}

And the following code:

use std::fs;
use std::process::exit;
use toml::{self, Value};

fn main() {
    let filename = "config.toml";
    let contents = match fs::read_to_string(filename) {
        Ok(c) => c,
        Err(_) => {
            eprintln!("Could not read file `{}`", filename);
            exit(1);
        }
    };

    let data: Value = match toml::from_str(&contents) {
        Ok(d) => d,
        Err(e) => {
            eprintln!("Unable to load data from `{}` {}", filename, e);
            exit(1);
        }
    };

    println!("{:?}", data);
}

Running this would result in:

Unable to load data from `config.toml` TOML parse error at line 14, column 9
   |
14 | key1 = {
   |         ^
invalid inline table
expected `}`

Which is unexpected since i believe the key/value pairs should be possible to span multiple lines.

Apparently, support for this was already merged in the TOML spec: toml-lang/toml#516 in this PR: toml-lang/toml#904

The spec is unreleased, see #397. Closing rn favor of that issue
