Spintax, short for spin syntax, is a list of text phrases, sentences, and synonyms separated by the pipe (|) character. Each group of keywords is enclosed inside curly ({}) brackets.
The Spintax parser picks a random keyword or sentence from the available choices and generates a unique sentence for each iteration. For instance, if the spintax is {Hello|Hi|Hola}, the output may contain either of these greetings.
Spintax can be nested as well like {{Thanks and|Best}Regards|Cheers}. Here’s a spintax parser written in JavaScript.
var text = "{{Hello|Hi|Hola}, How {have you been|are you doing}? " + "Take care. {{Thanks and|Best} Regards|Cheers|Thanks}"; var matches, options, random; var regEx = new RegExp(/{([^{}]+?)}/); while((matches = regEx.exec(text)) !== null) { options = matches[1].split("|"); random = Math.floor(Math.random() * options.length); text = text.replace(matches[0], options[random]); } console.log(text);
