squirrelly/src/nativeHelpers.js

Simple and powerful template engine that supports helpers, partials, filters, native code, and Express.

import { changeTags } from './regexps'
var nativeHelpers = {
  if: {
    helperStart: function (param) { // helperStart is called with (params, id) but id isn't needed
      return 'if(' + param + '){'
    },
    helperEnd: function () {
      return '}'
    },
    blocks: {
      else: function () { // called with (id) but neither param is needed
        return '}else{'
      }
    }
  },
  each: {
    helperStart: function (param, id) { // helperStart is called with (params, id) but id isn't needed
      return 'for(var i=0;i<' + param + ".length; i++){tR+=(function(hvals){var tR='';var hvals" + id + '=hvals;'
    },
    helperEnd: function (param) {
      return 'return tR})({this:' + param + '[i],index:i})};'

  foreach: {

    },
    helperEnd: function (param) {
      return 'return tR})({this:' + param + '[key], key: key})};'
    }
  },
  log: {
