This is a words counter. It just reads a large text file and counts words in it. The file is supposed to be larger than the available ram on the machine it´s running on.
Currently, the file I´m testing it with is [this one] (https://dl.dropboxusercontent.com/u/8311241/moby-dic.txt)
This was an exercise for a meeting (in German: Stammtisch) about functional languages, held in Berlin in the winter of 2013 [this one] (http://www.meetup.com/thefunclub/events/104441382/).
At august 2013, it counts words in 2 different ways.
A "vanilla" way, with a plain simple java reader reading the file sequentially.
Then the so called "Meikel´s version" based on the reducers library.
I used [iota] (https://github.com/thebusby/iota#readme) to represent the file as a vector-like structure so that the reducers library can be used on it.
I called it "Meikel´s version" because [Meikel Brandmeyer] (https://twitter.com/kotarak) suggested me the right way to call fold on the clojure mailing list.
Usage: load this namespace ( (use 'stammtisch.core) ) and then type either one of these lines
- (-main "path/to/the/file.txt" "vanilla")
- (-main "path/to/the/file.txt" "meikel")
- (-main "path/to/the/file.txt" "vanilla" "-b")
- (-main "path/to/the/file.txt" "meikel" "-b")
Of course you can build a jar with lein and call that.
