Since I wrote a pattern matcher in under 50 lines of code, I do not feel like setting up an entire project for it, but I do want to use it in other projects and share it with you.
Those great folks at Github added git access to Gists a while back, and it turns out you can make Leiningen run in a flat structure with a few extra lines of project.clj.
This allows you to make cute mini projects with git access that can be installed and published and are embeddable and sharable.
Here is the project.clj from my pattern matcher, I also pushed the jar to clojars.
First we tell Leiningen that our :source-path is the root dir. The other 2 lines are a bit of a hack to make sure only seqex.clj gets into the jar, Otherwise you'll get conflicts and broken jars.
