bbc.js v0.1.1

bbc.js

a tiny, flexible BBC parser for JavaScript

Install

npm install --save bbc.js

Usage

// require the module
const bbc = require('bbc.js')

// create a new parser object
const parser = bbc.createParser()

// parse BBC to html
// you'll need to style the tags yourself
const bbc = '[b]hello[/b] [i]world![/i]'
const output = parser.parse(bbc) // <span class="bbc-b">hello</span> <span class="bbc-i">world!</span>

// advanced: create a syntax tree
// allows you to render the BBC output however you please!
const tree = parser.tree(bbc) // [ /* lots of info and stuff about the BBC */ ]

Defining custom tags

// create an object
const tags = {
  // convert [b] tags to <strong>
  b: { render: text => `<strong>${text}</strong>` },

  // [img] tags
  // [img=sometext] will use "sometext" as the image alt text
  img: {
    render: (text, alt) => {
      if (alt) {
        return `<img src="${text} alt="${alt}">`
      } else {
        return `<img src="${text}">`
      }
    },

    // make sure this tag doesn't parse any tags inside of it
    deep: false,
  },
}

// pass the tags to createParser
const parser = bbc.createParser(tags)
let output

// outputs <img src="http://funny.website/funny_cat_image.jpg">
output = parser.parse('[img]http://funny.website/funny_cat_image.jpg[/img]')

// default tags are still parsed, but overwritten by custom tags
// outputs: <strong>hello</strong> <span class="bbc-i">world</span>
output = parser.parse('[b]hello[/b] [i]world[/i]')

For default supported tags, refer to src/index.js.

Caveats

• Doesn't support single line tags like [*] for list items
• Doesn't support advanced attributes, e.g. [img width=500]...[/img]
• No way to disable all default tags without overwriting them.
