I'm probably misunderstanding how LiveScript works, but how should I import another js file in an .ls file and make it compile? For instance I'd like to access the DOM document like:
el = document.getElementById 'app'
and load mithril.js (which is in the same local dir):
require! 'mithril.js'
But when compiling like:
lsc -c file.ls
this currently tells me that it can't find 'document' or any other mithril specific variables (such as 'm').
If you are compiling your files to Javascript and running them in a browser, then you don't need to require Mithril.
Just make sure it's added before your script.
For example:
# file.ls
element = document.get-element-by-id 'example'
m.module element app
Then run lsc -c file.ls
// file.js
(function() {
var element = document.getElementById('example');
m.module(element, app);
}).call(this);
This is now just a regular JS file with some references to Mithril variables. We need to remember that when we link them to our HTML.
<script src='https://cdnjs.cloudflare.com/ajax/libs/mithril/0.1.34/mithril.js'></script>
<script src='file.js'></script>
It's important that Mithril comes first.
If you want to require Mithril, in order to use it outside of the browser, then you'll have to slightly readjust your require statement.
If you look line 34 of the Mithril source, you'll see that m is just a local function. Then on line 1066 it tries to create a global variable m, if window exists. It won't do in Node/IO.js so instead it attaches the value to module.exports.
This means you'll have to use the value returned by require:
m = require 'mithril.js'
m.module! # works!
