fixedstr

Transforms fixed string to object and vice versa

Is available in both functional and object oriented styles, for backwards compatibility. Although we recommend using the functional style.

Functional style

Given the object definitions, you can either use currying to objectify/stringify, or use a factory function that curries for you.

Define objects

Object definitions can be created using a helper function, that takes in a property name and length of property value

const objectDefinitions: IObjectDefinition[] = [
  stringObject('foo', 2),
  stringObject('bar', 5),
  numberObject('baz', 3)
]

Currying method

curriedObjectify(objectDefinitions)('F Bar  012') // {foo: 'F', bar: 'Bar', baz: 12}
curriedstringify(objectDefinitions)({ foo: 'F', bar: 'Bar', baz: 12 }) // 'F Bar  012'

Factory method

const transformer = createFixedStr(objectDefinitions)
transformer.objectify('F Bar  012') // {foo: 'F', bar: 'Bar', baz: 12}
transformer.stringify({ foo: 'F', bar: 'Bar', baz: 12 }) // 'F Bar  012'

Object oriented style

import { FixedStr } from 'fixedstr'
const transformer = new FixedStr([
  FixedStr.str('foo', 2),
  FixedStr.str('bar', 5),
  FixedStr.number('baz', 3)
])
transformer.objectify('F Bar  012') // {foo: 'F', bar: 'Bar', baz: 12}
transformer.stringify({ foo: 'F', bar: 'Bar', baz: 12 }) // 'F Bar  012'
