parse and stringify for handling TOML encoded data.

Be sure to read the supported types as not every spec is supported at the moment and the handling in TypeScript side is a bit different.

Supported types and handling

• Keys
• String
• Multiline String
• Literal String
• Integer
• Float
• Boolean
• Offset Date-time
• Local Date-time
• Local Date
• Local Time
• Table
• Inline Table
• Array of Tables

Supported with warnings see Warning.

Warning

String

Due to the spec, there is no flag to detect regex properly in a TOML declaration. So the regex is stored as string.

Integer

For Binary / Octal / Hexadecimal numbers, they are stored as string to be not interpreted as Decimal.

Local Time

Because local time does not exist in JavaScript, the local time is stored as a string.

Array of Tables

At the moment only simple declarations like below are supported:

[[bin]]
name = "deno"
path = "cli/main.rs"

[[bin]]
name = "deno_core"
path = "src/foo.rs"

[[nib]]
name = "node"
path = "not_found"

will output:

{
  "bin": [
    { "name": "deno", "path": "cli/main.rs" },
    { "name": "deno_core", "path": "src/foo.rs" }
  ],
  "nib": [{ "name": "node", "path": "not_found" }]
}

import { parse, stringify } from "@std/toml";
import { assertEquals } from "@std/assert";

const obj = {
  bin: [
    { name: "deno", path: "cli/main.rs" },
    { name: "deno_core", path: "src/foo.rs" },
  ],
  nib: [{ name: "node", path: "not_found" }],
};

const tomlString = stringify(obj);
assertEquals(tomlString, `
[[bin]]
name = "deno"
path = "cli/main.rs"

[[bin]]
name = "deno_core"
path = "src/foo.rs"

[[nib]]
name = "node"
path = "not_found"
`);

const tomlObject = parse(tomlString);
assertEquals(tomlObject, obj);
