🔬 Nano implementation of TOML using Markty. 10x faster, 10x smaller :)

Demo

Quick start

For Node

npm install markty-toml

var toml = require('markty-toml')
// or using ES6:
import toml from 'markty-toml'

const someTOML = `
key = "value"

[deeply.nested.key]
secret = "Shhhhh"
`

console.log( toml(someTOML) )

// > prints:
// {
//     "key" : "value",
//     "deeply": {
//         "nested": {
//             "key": {
//                 "secret" : "Shhhhh"
//             }
//         }
//     }
// }

In-Browser

Find latest version here.

To get the umd version:

1. Observe the URL here and see the latest version used after @ like @0.1.1.
2. Just modify the URL to get something like this: https://unpkg.com/markty-toml@0.1.1/dist/martytoml.umd.js

Then just import it normally :

<script type="text/javascript" src="https://unpkg.com/markty-toml@0.1.1/dist/martytoml.umd.js"></script>

Then the exported name is marktytoml(), so you can just:

<script>
var someTOML = 'key = "value"\n[deeply.nested.key]\nsecret = "Shhhhh"';
console.log( marktytoml(someTOML) )
</script>

// > prints:
// {
//     "key" : "value",
//     "deeply": {
//         "nested": {
//             "key": {
//                 "secret" : "Shhhhh"
//             }
//         }
//     }
// }

FEATURES

• 🔬 Ridiculously SMALL:: 100 LOC, 1kb gzipped

• ⚡ Blazing fast ⚡ see benchmarks

• Use any of colon or equal sign: key : value works the same as key = value

• Single-line comments: # this = comment

• Single-line text withOUT double-quotes: key = single line without double-quotes allowed

• String literals: winpath = '''C:\\Users\\nodejs\\templates'''

• Multi-line text with double-quotes: key = "Multilined paragraphs with line breaks like this \n\n\n should be enclosed with double-quotes"

• Basic native data types (should not be enclosed by double-quotes):

  • strings like hello world
  • integers like 1, 2, 3...
  • float like 3.14
  • boolean like true, false
  • signed numbers like +27, -23
  • infinity like +inf, inf, -inf
  • hexadecimals like 0xDEADBEEF
  • octals like 0o01234567, 0o755
  • binaries like 0b11010110
  • dates like 1979-05-27T00:32:00-07:00, 1979-05-27

• Complex objects objects as value:

  • array of values like stuff = ["one", "two", "three"]
  • array of arrays like stuff = [[1,2], ["a","b"]]
  • inline tables like stuff = {"key" : "value"}

• Tables:

  [sub.sub]
  key = value
  

• Array of tables:

  [[sub.sub]]
  key = value1
  
  [[sub.sub]]
  key = value2
  

• Spaced keys when surrounded by double quotes like "spaced key here" = value

Example

string = hello I do NOT need double quotes

array = ["I", "still", "need", "double-quotes", "except for", 1, true, 3.14, ":)"]

other : hey look ! I can have a colon instead of an equal sign

sentence = "this is a long sentence
with line breaks
one here
and another here
so I need double quotes"

This will correctly parse to :

{
    "string" : "hello I do NOT need double quotes",
    "array" : ["I", "still", "need", "double-quotes", "except for", 1, true, 3.14, ":)"],
    "other" : "hey look ! I can have a colon instead of an equal sign",
    "sentence": "this is a long sentence\nwith line breaks\none here\nand another here\nso I need double quotes"
}

When should you use marktyTOML over other libs (or when you should NOT)

• 👶 Even though a lot of tests have been implemented, I will be slow to patch issues if any... so check if your use case match the tests before anything.
• Not TOML v0.5 compliant and not meant to be. For instance, here are UNsupported specs:
  • There is no errors mechanism to print from.
  • Handling colons : as key/value separator is not allowed in TOML v0.5 (only = supported)
  • Handling strings without " is not allowed in TOML v0.5 (strings must be enclosed by ")
• markty-TOML considers any TOML source like a database log:
  • when two identical nodes are set, the last one REPLACES the first: TOML sources are treated like a list of updates which AFTER PARSING returns a final state. This clearly goes against official TOML specs which aims to parse a given source as a final database state: thus two identical nodes would throw an error for the whole source.
