While the JetBrains folks work on a better solution , there are a couple of new options for people looking for better autocomplete for Laravel 4. Both are installed using Composer, use the Artisan command to generate a 'helper' file, and use reflection and parsing the Laravel docblocks to provides the necessary method documentation to autocomplete Laravel 4's aliased façades:
This one takes a very minimalist snapshot, extends the façade class, and just adds method signatures (I like it because it gives me an easy-to-read diff of the ongoing changes to the Laravel 4 API):
This one has more extensive configuration options and generates a more extensive file with better reflection of the docblock for each method:
I personally run them both, using mine for keeping track of the API and Barry's for autocomplete.
