Mytacism

Evaluates statically analyzable expressions in Javascript and can evaluate injected compile-time constants and functions. Inspired by static-eval, which at the time of writing was a promising but incomplete solution.

Installation

npm install --save-dev mytacism

Usage

Basic usage:

var mytacism = require('mytacism')

var options = {}
var source = '1 + 1'
var result = mytacism(source, options)

console.log(result.code) // 2

You can also pass values in the options parameter to be used in computations:

var mytacism = require('mytacism')

var source = '1 + a'
var result = mytacism(source, {values: {a: 2}})

console.log(result.code) // 3

You can also pass functions to be statically executed:

var mytacism = require('mytacism')

var source = '1 + foo(1)'
var result = mytacism(source, {functions: {foo: function(a) { return a + 2 }}})

console.log(result.code) // 4
