Re: clojure.java.jdbc connection pool example

Hi Josh, I would opt for using Tomcat 7 Pool API - http://tomcat.apache.org/tomcat-7.0-doc/jdbc-pool.html The following code wraps the pool api and provides reading a config file (ns foo (:require [clojure.java.io :as io]) (:import [java.io PushbackReader]) (:gen-class)) (defn conf [file

reference types (var, atom, ref, agent) and add-watch: deterministic order of notification

Hi, i got a question on reference type instances with attached watches. Consider a reference type instance R with a watch W attached by (add-watch R :watcher #(...)) and a n parallel activities committing a transition to R in some monotonic order 0..n-1. Does Clojure ensure that the function

What are the phases of the Clojure compiler?

Hi there, I wanne dive a bit more deep into the clojure compiler and I wonder whether it follows the std procedure for compiled languages Character Stream -> Scanner (lexical analysis) -> Token Stream Token Stream -> Parser (syntax analysis) -> Parse Tree Parse Tree -> Semantic Analysis -> Abstr

Interested in more expressive/dense Priority Queue Implementation

Hi all, I am working on graph search algorithms using a priority queue which is implemented by a sorted-set and a custom comparator. Elements maintained by the set consist of :node (nodename) :dist (current distance) as well as :visited (still to process). Only one element with node x is allow

distinction of defrecord instances in sorted-set-by does not work

Hi all, Consider the following record definition, a respective record instance as well as a sorted tree set with a custom comparator sorting first the :visited property and the by the :dist property of the record. (defrecord RDistance [node dist visited]) (def d (RDistance. "foo" 1 0)) (def

sorted-set-by with custom comparator frauds equality

Hi all, please consider the following record definition (defrecord RDistance [node dist visited]) as well as an instance and a tree set with a custom comparator ordering content first by :visited and after that by :dist (def d (RDistance. "foo" 1 0)) (def tree (sorted-set-by (comparator (jux
