These scripts require Alfred with the Powerpack installed. Without the Powerpack you won't be able to run any extensions.
These scripts assume Corona has been installed in /Applications/CoronaSDK and that there's a Corona Terminal executable. They also assume that iTerm 2 has been installed.
The Python script has only been tested against version 2.7.3.
Open Alfred's preference pane and add a new Shell Script. Name it as you please - I tend to use Launch Corona with iTerm 2. You might want to put the GitHub address in as the web address, in case you want to check for updates.
Click create.
Now you will see the configuration pane for the extension. Give it a sensible title (again I use Launch Corona with iTerm 2) and description (Launches project in Corona).
Next you'll need to specify the keyword or command you want to use to run this script from Alfred. I use corona, but go with what ever is memorable for you, I would stick to a single word though.
In the command box enter the following:
python -u corona_launch.py __path_to_search__ {query}
Replace path_to_search with the folder where you want the script to look for your projects. On my mac that's a directory called Programming in my home directory, so I pass in /Users/username/Programming. The more specific the directory, the faster the script will run.
On the Parameter dropdown select "Required Parameter".
If you have Growl installed you can get messages from the script to appear as notifications. To do that click on the Advanced Tab over the command field and check "Display script output in Growl".
Next you'll need to manually copy the Python and AppleScript scripts into the directory Alfred has created for this extension. That will be in the Alfred/extensions/scripts/ directory, which will either live in your Dropbox folder if you have syncing enabled, or (I think) ~/Library/Application Support/
With everthing set up simply type corona __project_name__ in Alfred, if everything works the scripts will start iTerm 2 and launch Corona Terminal with the project you requested.
Basically the python script searches for a folder with the name you passed as the argument to Alfred. It will restrict its search to the directory you specified in the command box in the configuration pane for the script. If it finds a directory with a matching name (case insensitive), then searches all subdirectories of that folder for a main.lua file. If it finds that, it passes that to the applescript which tells Corona Terminal to open it!
Complicated, but worth it!
In my experience, Corona Terminal won't accept file paths with spaces in them. So trying to launch a main.lua file in "Raging Birds" directory won't work unfortunately.
