Generate a single formatted list item, allowing you to easily generate lists with proper indentation, bullets, numbers or other leading characters.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.

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'
