TOML-j0.4

As its name TOML-j0.4 says, this is a TOML v0.4.0 compliant parser built with PEG.js. You can customize it easily by modifying the grammar file toml.pegjs.

Usage

You can install it via npm install @webreflection/toml-j0.4, or just include the script toml.js in your web pages.

// import * as toml from '@webreflection/toml-j0.4';
var toml = require('@webreflection/toml-j0.4');

try {
    var data = toml.parse(src);
} catch (err) {
    if (err instanceof toml.SyntaxError) {
        // do something
    }
}

• toml.parse only accept one argument — data text in TOML
• The instance of toml.SyntaxError has these properties:
  • line: the line number
  • column: the column number
  • offset: the zero-based offset from the start of the text
  • message: error message

There is no other API for now.

Known Problems

• This parser does not support big integer, until a major version change happens.

  All numbers are floats. Any integer bigger than Number.MAX_SAFE_INTEGER (9007199254740991 < 2^63 - 1) or smaller than Number.MIN_SAFE_INTEGER (-9007199254740991 > -(2^63 - 1)) is not safe when being converted or used as pure integer!

  But you can still store big integers as strings.

• RFC 3339 is not the sole criterion of truth.

  You can't imagine how terrible all minitue details of the standard are! So don't expect some date-times will work anytime and anywhere, for instance, "2015-02-29T00:00:00Z", "2015-12-25T24:00:00Z", "2015-11-10T00:60:00Z", "2015-11-10T00:00:60Z", "2015-12-25T24:00:00+24:00", "0000-01-01T00:00:00Z".
