core.logic - DCG

Hi, I'm trying to write a small parser using DCG, but when I use the code below -- parser.clj --- (ns compiler.parser (:refer-clojure :exclude [==]) (:use [clojure.core.logic] [clojure.core.logic.dcg] ) ) (def-->e token [tg x] ([_ ?tk] [?tk] (

Re: Why do Clojure collections have (seq) rather than supporting the ISeq interface directly?

Mostly efficiency. A Seq generally gives you access to `first` and `rest` in constant time. Vectors, to take one example, cannot give you `rest` efficiently, but a Seq backed by the vector can. Clojure lists are implemented as singly-linked lists, which do have first/rest pointers, so they impl

Calling Clojurescript code from Clojure

Modelling for DAG with identity map - or not?

Hi, I'm a newbie at clojure and functional programming and I'm toying with the idea of switching a project of mine to clojure. Sorry for a long first post, and it may also be a bit abstract - but you never know before trying :) In my previous OO prototype the domain is modelled via 2 basic pri

Why do Clojure collections have (seq) rather than supporting the ISeq interface directly?

...Just trying to understand the rationale between Clojure's design here. As I gradually get deeper into Clojure, I've been highly impressed by how well thought-out everything is, so I'm sure there is a very good reason for this one too. The question is: Why are Clojure's built-in collections *

Re: Can't start Rhino repl for ClojureScript

Leiningen works under Windows (as lein.bat). I'm not sure if it works under Cygwin. I've encountered problems in the past with Cygwin because the Java executable is the Windows version, using Windows path-separator characters, but scripts expect Unix-style path separators. Try downloading Lein

Re: Using println inside a for print out some "nil"

println is a function that has the side effect of printing a string to the output, but it also has a return value of nil. When working at the REPL, these can sometimes be mingled together due to the order of evaluation. If you want to do something like 'for' but only for the purposes of side e

I've used it in conjunction with goog/base due to a problem with simple/advanced compilation. I'm not sure if things have changed since I encountered this problem, or if there is something else I'm doing wrong. See the code and comment below. The deactivated "this-as" code only worked with whit
