## Tern Demo

// Use ctrl-space to complete something // Put the cursor in or after an expression, press ctrl-i to // find its type var foo = ["array", "of", "strings"]; var bar = foo.slice(0, 2).join("").split("a")[0]; // Works for locally defined types too. function CTor() { this.size = 10; } CTor.prototype.hallo = "hallo"; var baz = new CTor; baz. // You can press ctrl-q when the cursor is on a variable name to // rename it. Try it with CTor... // When the cursor is in an argument list, the arguments are // shown below the editor. [1].reduce( ); // And a little more advanced code... (function(exports) { exports.randomElt = function(arr) { return arr[Math.floor(arr.length * Math.random())]; }; exports.strList = "foo".split(""); exports.intList = exports.strList.map(function(s) { return s.charCodeAt(0); }); })(window.myMod = {}); var randomStr = myMod.randomElt(myMod.strList); var randomInt = myMod.randomElt(myMod.intList);

Demonstrates integration of Tern and CodeMirror. The following keys are bound:

Ctrl-Space
  Autocomplete
Ctrl-I
  Find type at cursor
Alt-.
  Jump to definition (Alt-, to jump back)
Ctrl-Q
  Rename variable

Documentation is sparse for now. See the top of the script for a rough API overview.
