TabJson

Turns tab-spaced new lines into an array of populated objects without relying on the call stack.

Install

npm install tabjson --save or yarn add tabjson --save

Example

const tabjson = require('tabjson')

const list = tabjson(`bobby
  #age: 18
  email: bobby@somedude.com
  @preferences: stew, brooms, ducks
  wallet
    #amount: 16
    currency: USD
sally
  #age: 45

      @#favoriteNumbers: 7, 14`)

console.log(JSON.stringify(list, null, 2))

Roadmap

• Add support for object arrays (@ and no colon)
• Add path referencing ($)
• Add inline function processing via () => {}
• Add template literal support for new lines (`)
• Add support for regex types (?)
• Add tests that make sure things work in weird cases
• Add syntax error and recommendation detection
