How do I preserve directory structure when compiling CoffeeScript?

Question

I am new to Coffeescript and I wonder where I should put them.

Eg. I have my app folder:

app/app.js
tests/unit/all.js
etc

When I use the "coffee" runner on node.js to watch my files in the root folder it will generate js files to a folder I specify eg. js.

So if the folder to be watched is looking like this:

app/app.coffee
tests/unit/all.coffee
etc

JS files will be generated to:

js/app.js
js/all.js
etc

As you can see I lose my js folder hierarchy.

How are you supposed to retain your original folder hierarchy?

Thanks

Answer 1

I believe you want

coffee -cwo js .

That will compile app/foo.coffee to js/app/foo.js, and test/bar.coffee to js/test/bar.js.

As long as you stick to passing folder names to the coffee command, rather than individual file names, directory structure will be preserved.
