I know IDE support isn't as good as in java but, after looking at your code, yes, there is something your not aware of and that is why clojure is giving you a hard time. The main thing to keep in mind is that when coming from java/scala, you'll have a hard time adjusting to clojure, and you're making it harder by trying something so inherently full of state. I understand the need to tackle problems that we like, but without a good understanding of the language you're going to have a really hard time, and that reflects in your code. First, understand the philosophy of clojure. look here http://tinyurl.com/5u3suzf and here http://www.infoq.com/presentations/Simple-Made-Easy If you understand that philosophy and identify with it then try to solve very small problems(preferably with little to no inherent state), and try to be as idiomatic as possible. To understand how to solve problems idiomatically, read books (e.g. joy of clojure) ask in the IRC or here on how to solve particular problems and complement this with understanding the key ideas of libraries that excel in this(e.g Ring). When you have a good understanding of the language and underling philosophy, invest some time to think about your problem and how to properly express it clojure. > > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v2.0.14 (MingW32) > Comment: Using GnuPG with Mozilla -http://enigmail.mozdev.org/ > > iQIcBAEBAgAGBQJOtSkdAAoJENRtux+h35aGeeQP+gJbQdNSZEdEIgjVFC/VZvRe > z1Rh9Z8xVwxbuyl/kx1GMLU3jZxJKkhp0OIp7RLbDgjwFFzwBnQ0CZSeuHd9bFD/ > S5Vmf6tXB4AdC3u3a7wZilEQuSuq+ARtJhMKdGIQfoXgqDYA7JwOvV8ZkpiR2T2d > pKqswheRVstBqo9/xyinfuLsJMujDlF9NshoIC0n1b/L4tzddq/kgzIATcg/NJ4N > I0Qd1lqGC1THU2nHtiaSR66KQE5Ciq22FN0nVoT3jW9EU/kJ9tao7L6SUTY3tcaA > th8mxKLYId/NrbRmsYUTyWe6O30HAUTLLFEnImYTW2fUMdwRYeAoZGc7t5V3yJ/p > dU4JN0dGA/ADbdTItykaao1DtGI2/kGe6p9VaKk3IPCVAOio9UwgOCUQylTKqy7M > CWbrDcSFCQs5pTY1Sw5We9LV2VOBoTsai6vH/qE7t98mJLVf0wHvLLIBOkf/QO5a > HuSyCJRpOrWQF2jbooDqAbaJAa6huxLQjMeO9Ri4sDx2gDRYsf9Fmdjp4TFWWjdZ > O5HEzhUR165peQHo4RQLLf8dnlkibsdbx60n+VJ0E4iE7ID+hBOFC76bAllnAS1K > Q8HqXUogMi/ZLXIAB4BA83q71IEDVcytuYAn9Ku2FQLrmWCiOD57uMhSLjtzK/8J > TIuaLwipARdzsqi/piwl > =MnRq > -----END PGP SIGNATURE----- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
