This is pretty cool. @larrytheliquid has created a Gitorial on how to build a library in Clojure. TDD style.

Gitorial? Larry’s blog post explains the concept:

…this presentation was captured in the Git revision control system. Every commit has a commit message that explains the “next slide” of the presentation. People can then view diffs between commits to quickly see what changed

Navigate to the first page of the commit log and follow along. The real power, as Larry explains, comes from being able to checkout any revision and play with the code.

Once the repository has been downloaded, you are able to check out any particular revision. Because the library has passing tests at every commit (unless otherwise noted), you are able to create a branch and play with the code with the backing of tests.
