@architect/parser

@architect/parser

.arc is a simplistic text format for storing structured data; @architect/parser is a function that accepts text and returns a plain JavaScript Object

The format:

• Starts with a @section
• Sections start with @
• Sections contain either scalar values, Vector or Map
• Scalar values are either String, Number or Boolean
• Vector values are space seperated scalar values on a single line
• A Map is defined by a scalar value followed by Vectors indented two spaces
• Comments follow # symbols

Install

npm i arc-parser

Example Usage

var parser = require('arc-parser')
var fs = require('fs')
var text = fs.readFileSync('./some-arc-file.txt').toString()
var result = parse(text)

Example

Input

# this is a comment
@section-one
simple-string-value # String
another-value 
4.2 # Number
true # Boolean

@another-section-of-vectors
vector of values 
vector tuple

@this-section-has-a-map
hello-world
  name some-value

Output

{
  "section-one": [
    "simple-string-value",
    "another-value",
    4.2,
    true
  ],
  "another-section-of-vectors": [
    ["vector", "of", "values"],
    ["vector", "tuple"]
  ],
  "this-section-has-a-map": [{
    "hello-world": {
      "name": "some-value"
    }
  }]
}

Experimental Support

To facilitate interop the main module exported here has the additional methods that are specific to the Architect .arc format:

• parse.json(jsonText) returns .arc compatible Object
• parse.yaml(yamlText) returns .arc compatible Object
• parse.json.stringify returns .arc compatible String
• parse.yaml.stringify returns .arc compatible String

It is worth noting that parse is a generic .arc format parser in a similar vien to yaml and json. the impl above parse.json and parse.yaml are Architect grammer specific dialects of json and yaml.
