The ti_coffee_plugin simply scans your Titanium project's
Resources folder at build time and looks for files with the
.coffee extension. When it finds such files, it runs the CoffeeScript compiler (
win.coffee would become
Requires Python 2.5, because the
hashlib module is used.
First, of course, you'll need the
coffee command available on your system. If you can't go out to a command-line/terminal and successfully execute
coffee, then be sure to setup CoffeeScript correctly.
Also, if you're on OS X and you used Homebrew to install CoffeeScript and Node.js, GUI applications such as Titanium Developer and Titanium Studio -- which are precisely the apps that launch your Titanium project's build process and thus this plugin -- might not be able to successfully execute
/usr/local/bin is not in the PATH by default for GUI apps, and changes to
/etc/paths, etc., are not useful for GUI apps. The easiest solution is to simply symlink
/usr/bin, which is in the PATH:
$ sudo ln -s /usr/local/bin/node /usr/bin/node $ sudo ln -s /usr/local/bin/coffee /usr/bin/coffee
If you'd rather not do that, you can muck around with
~/.MacOSX/environment.plist following Apple's instructions.
In the folder which houses your Titanium SDKs -- on OS X this would be
/Library/Application Support/Titanium, create a
plugins/ti_coffee_plugin/1.0 folder. Put the plugin.py from this repository into that folder. So on OS X you would have this file:
Next, you need to tell your Titanium project to run this plugin when the Titanium build scripts build your project.
Build-time plugins for Titanium projects are invoked if the plugin is registered in the project's tiapp.xml file. For the ti_coffee_plugin, you could do it like this:
<!-- This is a child element of <ti:app> in tiapp.xml --> <plugins> <plugin version="1.0">ti_coffee_plugin</plugin> </plugins>
sample/ folder contains a very simple
app.coffee as a proof-of-concept. You can copy that file into a new project, then run the project to see how it works. To do that successfully, you'll also need to update your
tiapp.xml following the example inside
Your .coffee files will also end up in the application package that gets delivered to the device/simulator/emulator. Unfortunately, the Titanium build plugins don't (currently) get notified when the packaging is about to occur. They are just notified once: before the build begins. Of course, your .coffee files are plain text and the packaging (at least on Android, but I imagine on iOS as well) compresses them.
You will not be able to take advantage of Titanium Studio's code assist features (code completion, etc.) if you're tying in CoffeeScript.
If you have a JS runtime error, the line number it gives you most likely will be considerably off from the line number in your
