OMG! CodeMatch!

CodeMatch is apparently a search-based Eclipse plugin that seems to have organized an unknown number of small snippets into parameterized macros described by pattern-like sentences. As you code, you search for those snippets, and the code is built before your eyes.

This rocks. If it retained the pattern-level semantic information it would rock harder - I wonder if those snippets are open source? This is a service - the snippets are online in their own database and seemingly accessible only through their plugin, so it looks like the answer is no.

The "getting started" page [here] is a good textual rundown of how things work. This is an incredibly fascinating development.
