Install

Install with npm:

$ npm install --save list-item

Usage

const listitem = require('list-item');

Examples

Basic list

Generate a list using default bullets and indentation:

const listitem = require('list-item');
const li = listitem();
 
let list = ['a', 'b', 'c', 'd', 'e'].map((ele, i) => li(i, ele));
console.log(list.join('\n'));

Results in:

- a
  * b
    + c
      - d
        * e

Roman numerals

Generate roman numerals in increments of 10.

const listitem = require('list-item');
const romanize = require('romanize');
 
// specify `chars` to pass to fill-range, and use the callback 
// to modify generated numerals
const li = listitem({ chars: '1..100..10' }, (indent, ch) => {
  return indent + romanize(ch) + '.';
});
 
// generate a formatted list!
let list = ['a', 'b', 'c', 'd', 'e'].map((ele, i) => li(i, ele));
console.log(list.join('\n'));

Results in:

I. a
  XI. b
    XXI. c
      XXXI. d
        XLI. e

API

listitem

Returns a function to generate a plain-text/markdown list-item, allowing options to be cached for subsequent calls.

Params

  • options {Object}: pass options to customize list item characters, indentation, etc.
  • options.nobullet {Boolean}: Pass true if you only want the list iten and identation, but no bullets.
  • options.indent {String}: The amount of leading indentation to use. default is ``.
  • options.chars {String|Array}: If a string is passed, fill-range will be used to generate an array of bullets (visit fill-range to see all options.) Or directly pass an array of bullets, numbers, letters or other characters to use for each list item. Default ['-', '*', '+']
  • fn {Function}: pass a function fill-range to modify the bullet for an item as it's generated. See the examples.
  • returns {String}: returns a formatted list item

Example

const li = listitem(options);
 
li(0, 'Level 0 list item');
//=> '- Level 0 list item'
 
li(1, 'Level 1 list item');
//=> '  * Level 1 list item'
 
li(2, 'Level 2 list item');
//=> '    + Level 2 list item'
