xexpression

$3

This is packaged as AMD module.

``js

/1. Simple version, just evaluate one expression two times with different variables

// Input from user (e.g. search filter)
var expression = 'transactions <= 5 and abs(profit) > 20.5';

var parser = new Expression();

var aResult = parser.parse(expression,null,{
variables:{
transactions: 3,
profit:-40.5
}
}); //returns 1

var aResult = parser.parse(expression,null,{
variables :{
transactions: 3,
profit:-14.5
}
}); //returns 1

2. more advanced example, thing of a console input with real time feedback and autocompletion

var expression = 'send{{Volume+4}} my garbage string {{transactions*2/Volume}}';

var parser = new Expression();


var aResult = parser.parse(expression, null, {
variables: {
Volume: 2,
transactions: 3
},
delimiters: {
begin: '{{',
end: '}}'
}
});//returns 'send6 my garbage string 3' neat ?
