Technically you can _submit_ pull requests but Clojure and contrib projects cannot _accept_ them.

I try and use a greedy parser combinator as the next jump, and as example of hiding arguments. String parsing is a small, yet non-trivial example, that doesn't require domain knowledge. Something like: (defn result [value] (fn [string] [value string])) (defn pred [predicate] (fn [string] (if (predicate (first string)) [(first string) (rest string)]))) (defn orp [f g] (fn [string] (or (f string) (g string (defn bind [parser f] (fn [string] (if-let [[result s2] (parser string)] ((f result) s2 (defn many [parser] (let [f (bind parser (fn [h] (bind (many parser) (fn [rst] (result (cons h rst))] (orp f (result [] (def letter (pred #(if % (Character/isLetter % (def word (bind (many letter) (fn [w] (result (apply str w) (word "foo") ;=> ["foo" ()] The closest I see to an implicit this is: ((bind word (fn [w1] (bind (pred #(= % \space)) (fn [_] (bind word (fn [w2] (result [w1 w2]))) "foo bar baz") ;=> [["foo" "bar"] (\space \b \a \z)] Here word and the space predicate are called on the string, but its only ever mentioned as the argument. However, it is kinda ugly without a macro to hide all the bind/fn pairs. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

This does not necessarily include a specific version. “Instructions for including the library as a dependency in Maven / Leiningen” A link to eg. mvnrepository.com satisfies this for Maven Central. “Links to the available releases on Maven Central and oss.sonatype.org” Actually not providing a specific version in the dependency explanation would force people to understand what they are doing.

Because Clojure/core have decided - after quite a bit of discussion - that providing specific version details is better for users. I certainly agree with them. One of the most common questions I hear about libraries in general is "How do I add this to my project?" - users want a specific string they can just copy'n'paste into project.clj without needing to click through to Maven and figure out group / artifact / version stuff! -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ World Singles, LLC. -- http://worldsingles.com/ "Perfection is the enemy of the good." -- Gustave Flaubert, French realist novelist (1821-1880) -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Attractive examples of function-generating functions
I'm looking for medium-scale examples of using function-generating functions. I'm doing it because examples like this: (def make-incrementer (fn [increment] (fn [x] (+ increment x ... or this: (def incish (partial map + [100 200 300])) ... show the mechanics, but I'm looking for examples that would resonate more with an object-oriented programmer. Such examples might be ones that close over a number of values (which looks more like an object), or generate multiple functions that all close over a shared value (which looks more like an object), or use closures to avoid the need to have some particular argument passed from function to function (which looks like the `this` in an instance method). Note: please put the flamethrower down. I'm not saying that "looking like objects" is the point of higher-order functions. I'll give full credit. - Brian Marick, Artisanal Labrador Contract programming in Ruby and Clojure Occasional consulting on Agile -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Functional Composition (with Overtone)
Hey everyone, Chris Ford gave a talk on functional composition with Overtone in London recently and it's now online: http://skillsmatter.com/podcast/home/functional-composition Chris really delivers a beautifully paced introduction to a huge range of fundamental musical concepts through the "transmission vector" of Clojure. It's truly fantastic to watch how seemingly magic and untouchable concepts such as classical music can be destructured piece by piece into understandable Clojure code.

Re: Writing code to get the source of a function
The source function only works for function where the .clj where the function is defined is in the classpath.

Re: What concurrency models to document?
Hey, A bit late to the party but something I'd love to see in the book is an approachable summary/description/use cases of the main concurrency models at play today: event-based and thread-based concurrency. I see this section helping people compare Clojure with something like Node.js or Ruby with EventMachine (Clojure has aleph[1] for that purpose). There is a lot of controversy around the topic and I believe even a brief discussion on the subject will be beneficial. This paper has a lot a good info: http://static.usenix.org/events/hotos03/tech/full_papers/vonbehren/vonbehren_html/ (it is biased towards a threaded model though). Would this be way out of scope for your book? - Even not exactly what you were after when you asked about concurrency models?

Writing code to get the source of a function
Dear all, I am trying to write some code that would take a function name, get its source code, and create a new function based on the source code. Unfortunately, the function 'source' from clojure.repl doesn't seem to be working for the functions I define. Here is my code: (ns test-src.core (:require [clojure.repl])) (defn my-function [x] (+ x 1)) (defn print-src [] (println (clojure.repl/source my-function))) When I try print-src on the repl, I get: test-src.core> (print-src) Source not found nil nil So my question is: how can I access to the source code of the functions I write?

Re: core.cache 0.6.2 is not available from Central
Meikel, For you (and me) it's not a problem; I have even looked at pom.xml files in certain cases to figure out the latest version, etc. but "normal" people don't care, they wish to get started as soon as possible. People don't read README files as well, but on Github README files are rendered as the home-page for a repository by default so we should try to put in as much useful information right there as possible. At the very least, you'd want to mention the latest stable release (a SNAPSHOT as well if feasible) and the repository (in case it's not on either central or clojars).

Sure, it does look as one to me as well. Should I do something about it? Create an issue somewhere?

I tried to move to Coljure 1.4 (as it's the current version) I could move from clojure.contrib.str-utils2/split to clojure.string/split but I couldn't move from clojure.contrib.str-utils2/grep to clojure.string/grep because it seems that in clojure.string there's no grep function Is grep gone ?
