Elder.js Shortcode Parser

This is a fork of meta-shortcodes which adds async support and has updated the tests to support async.

Generic shortcodes parser with support of attributes and single/pair tags.

Usage

var should = require("should");
var ShortcodeParser = require("meta-shortcodes");

var parser = ShortcodeParser();

parser.add("test", async function (opts, content) {
  return content.toUpperCase();
});

parser.add("nested", async function (opts, content) {
  if (!opts.multiply) return "Missing multiply attribute!";

  var out = [];

  for (var i = 0; i < opts.length; i++)
    out.push(opts[i] * parseFloat(opts.multiply));

  return out.join(" ");
});

var input =
  "Sample [test]shortcode content [nested multiply=2 2 4/] is upper[/test] case!";
var output = await parser.parse(input);

output.should.eql("Sample SHORTCODE CONTENT 4 8 IS UPPER case!");

Instalation

npm install meta-shortcodes

API

#constructor(opts)

opts = {

  closePattern: "\\]",
};

#add(shortcodeName, handlerFunction)

Registers new shortcode

Param	Type	Description

Shortcode examples

#Self-closing
[name argument1 argument2 key=value key=value/]

#Pair
[name]content[/name]

#Quoted arguments
[name "argument 1" 'argument 2' "key is"="long value"/]

#Escaping quotes in arguments
[name "argu\"ment" "ke\"y"='val\'ue']

#Escaping of entire shortcode
\\[this shortcode is not processed /]

Testing

Using alternative brackets

var should = require("should");
var ShortcodeParser = require("meta-shortcodes");

var parser = ShortcodeParser({
  openPattern: "\\{{",
  closePattern: "\\}}",
});

parser.add("test", function (opts, content) {
  return content.toUpperCase();
});

var output = parser
  .parse("Sample {{test}}upper{{/test}} case!")
  .should.eql("Sample UPPER case!");
