README.md

Learning (aka. playing with) Clojure

  • first heard about it early 2012 (I think)
  • dipped my feet in a few times since then
  • came across (i.e. read or saw things they did) a few interesting people using/writing Clojure in interesting way (fogus, Rich Hickey, Chris Granger)
  • now reading 'The Joy of Clojure' (and enjoying it)

Tools

  • mostly LightTable
  • previously Vim with the VimClojure plugin, but not right now (LightTable 'feels' more interactive to me and what I miss most from Vim (keybindings) will be in LT soonish, I also think that something like LT has more potential to be extensible and has a much saner extension language)
  • the clj repl

Little thoughts

  • a lot of interesting people with interesting ideas use Clojure, so maybe it encourages thinking about problems first? you can simply start coding something before having any idea what you're going to do (which is both good and bad).

Giggles & quibbles

  • the giggles
    • homoiconic
    • has macros
    • good feature inheritance (supposedly, not as in OO)
    • lots of cool projects (datomic, matchure, ring, lighttable, typed-clojure)

  • the quibbles

    • the dynamic type-system continues to bite me could be my fault, but I often jump right in without reading the whole documentation and have spend too much time tracking weird errors down that were all fixed by changing one place in the code
    • learning new libraries without sufficient docs/tutorials (e.g. what are the arguments to this function, what does this map mean; maybe clojure wants me to think differently)

    • the jvm overhead is bad for my little computer (too slow, too much memory consumed)

      it also makes it difficult to quickly explore some ideas without creating a new project (in most cases, mostly to get libraries), starting a jvm... etc.

      i'd really love a version of clojure without this overhead, even if it is a lot slower. maybe clojure-scheme could be that.

Hickups

Some examples for the quibbles.

  • (if (= something something-undefined) true-expr false-expr) not throwing an exeption for something-undefined being not defined
