Re: Keyword names and namespaces
I see, thank you for linking to the ticket, Phil that really clarifies things.

Re: Behaviour of clojure.set functions with non-sets.
It's not free.
(defn set
Returns a set of the distinct elements of coll.
{:added 1.0}
[coll] (clojure.lang.PersistentHashSet/create ^clojure.lang.ISeq
(seq coll)))
It seems to go element by element, irrespective of whether it was
given a hashset.

It looks like the behaviour of some clojure.set functions is either
undefined or possibly erroneous when called with non-set arguments:
user (clojure.set/union #{:a :b} [:b :c])
#{:a :c :b}
user (clojure.set/union #{:a} [:b :c])
[:b :c :a]
Seems likely that the behaviour in such cases is just undefined, but I
wonder if it would be worth calling set on each argument just to avoid
weird edge-case bugs. Is it a cheap operation to call set on a set?

But I'll take your point that we shouldn't count on the current behaviour continuing. FWIW, in Common Lisp no validation is done on symbol names; they can be arbitrary strings. Strictly speaking, the reader doesn't validate them, either, but in order to parse them it has to place some restrictions, e.g. to disallow ambiguous strings like foo::bar:baz. However, the CL reader allows one to quote characters in symbol names, so you can effectively intern any string with it: for example, foo::| abCDef gh:123::@| is a valid symbol in the FOO package. Personally I don't see any value in restricting what can be interned; symbols are not necessarily only used as keyword or variable names. However, consistency between how a symbol is printed and how it is read back in is important. In Clojure, also, Java interop could be a problem in principle if Clojure symbols are to be used as class, method or field names; however, in such cases the problem can be solved locally, by disallowing certain symbols when compiling to a Java class, or by mangling them.

Improving Contrib
We are taking several steps to improve contrib and the facilities used to host Clojure development. The goal is to make it easier and more desirable to work on the Clojure project, and encourage more libraries to be developed within the project. There are several impediments to people working in or on contrib, and within the Clojure project. The community is obviously vibrant, as there are many independent libraries. But fewer people work on Clojure itself or on libraries intended for inclusion in Clojure. I'd like that to change. Although there have been recent efforts to make contrib more modular from the Maven perspective (thanks Stuart Sierra!), it is still a monolithic repo. Logically, the individual libs are more independent than the repo structure would indicate. It should be much easier to obtain, build, version, distribute, branch, test and modify individual libraries. Some of these problems flow from historical choices made by the project. In particular, without money, boxes and the staff to maintain machines on the net, I chose free project hosting service providers - first SourceForge, then Google Code, and most recently GitHub and Assembla. In all cases, there was a tension between project and user management and code granularity. It would have been difficult to manage the contrib libs as independent projects/repos. Several things have changed recently that enable a better strategy. GitHub has added an organization feature that lets us manage users at the organization level and put multiple repos under the organization. Contegix is donating a hosted box so we can run our own server (thanks Contegix!), and the Clojure/core team now exists and is (voluntarily, and among other things) providing much needed administrative support (thanks Clojure/core team!). The New Model Contrib libraries will be independent repos under the Clojure GitHub organization. All contributions to these libraries will be contributions under the CA (therefor, no pulls). The primary authors will have substantial independence in terms of versioning. branches and releases etc, and it will be easy to obtain and work on a contrib library a la carte. We will be moving from Assembla to a self-hosted installation of the Atlassian suite, which they generously make available for free to open source projects (thanks Atlassian!). It will give us a superior wiki and bug tracking system. We will initially have support for Jira, Confluence and FishEye, and will be able to centrally manage users with Crowd. Individual contrib projects will get documentation and planning space in the Confluence wiki, and a dedicated subproject in the Jira tracking system. Contrib is not a Standard Lib People often ask if contrib constitutes a standard library. It has always been a goal of contrib to support exploratory work of the community that might or might not become part of Clojure proper, so the simple answer is no. As volunteer open source efforts, each library is likely to differ in quality, maturity and attention level. In that respect, they don't differ from all of the other libraries on GitHub. And with the new model, you will be using the same criteria in evaluating a contrib library as you do any other open source library - documentation, participation, recommendations, activity, stability, bug reports etc. And you'll only consume as much of contrib as you desire. Libraries will succeed on their merits. It is our plan to reserve the 1.0.0+ designations for the more mature and widely accepted libraries when they reach that point. That's as much sanctioning as I anticipate for the near term. You've Got to be In it to Win it Why work within the Clojure project? Because you want your work to eventually become part of Clojure and the Clojure distribution. You want to tap into the core development effort and have an impact on it. You are interested in collaborating on how best to make a set of things work together in a coherent way, as Clojure does. Isn't the GitHub free-for-all easier? Yes, but with this new setup, only very slightly so. The easiest thing is not necessarily the best thing. Participating in a project involves cooperation and compromise, and stewardship implies responsibility. Moving Forward We will be working on getting the existing contrib libraries moved over to the new model. Meanwhile, I'm happy to announce three new and exciting contrib libraries that are kicking off the new model: Chris Houser's Finger Tree - http://github.com/clojure/data.finger-tree Chas Emerick's Network REPL - http://github.com/clojure/tools.nrepl Michael Fogus's Unification Library - http://github.com/clojure/core.unify These are terrific contributions, and good examples of things that will have the greatest impact by being part of the Clojure project. Thanks guys! There are still some infrastructure things being worked out as regards Confluence, Jira etc, and the Conj is keeping everyone busy at the moment, but I expect this all to be

getting started with clojure
lastly i have been messing around with new languages just to try them out. in trying out coljure (only functional language i have tried yet) but i can compile anything longer than one line. im using Coljure Box but im very confused as to how i am supposed to write code that dose more than one thing. basically how do i save files, compile them, then run them? -- You received this message because you are subscribed to the Google Groups Clojure group.

Or maybe it's the clojure web site making things difficult to find. Nuts, I happened to apply for my Chickasaw Nation citizenship today - which gives me tribal voting rights, free health care at tribal hospitals and clinics, the ability to get grants for education, housing, free laptops, etc, etc, etc. That was less work than being allowed to submit a bug to the issue tracking system for clojure (unless I just didn't find the right page). It was also more work than submitting patches looks to be for apache, django, gnu, fedora, or openoffice (from your list, though it sounds like openoffice may changed for the worse) or I know to be for FreeBSD, PostreSQL, OpenSolaris, Python, Cheetah, to name some I've been using for a while. Sure, many of them require you to create an account to submit any bug report. But that's straightforward, and a not unreasonable anti-spam measure. Some even require you to click a checkbox assigning the rights to anything you submit to the project in question as part of that process. But I can still contribute patches to these projects without having to print, sign and post any kind of developer agreement. mike -- Mike Meyer m...@mired.org http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information.

Re: getting started with clojure
I use Leiningen to compile and run my Clojure projects. I create a new project with Leiningen, use Clojure Box to edit code and try out one line at a time, then switch back to Leiningen for downloading libraries or for compiling my own project into a library or program. http://github.com/technomancy/leiningen Or if you are just working with one file, it may be simpler to put a bunch of your code into a file and use the load command from the prompt in Clojure Box.

Re: getting started with clojure
I have written a tutorial just for beginners, that will quickly get you started on clojure. This tutorial was written based on my own experience learning clojure. When learning a new language I am impatient, and like to dive into thick of things immediately. Hopefully this will do the same for others also. http://fasttrackclojure.blogspot.com On Wed, Oct 20, 2010 at 5:25 AM, ishkabible j...@ehrlichks.net wrote: lastly i have been messing around with new languages just to try them out. in trying out coljure (only functional language i have tried yet) but i can compile anything longer than one line. im using Coljure Box but im very confused as to how i am supposed to write code that dose more than one thing. basically how do i save files, compile them, then run them? -- You received this message because you are subscribed to the Google Groups Clojure group.

I wish you the best of luck. in trying out coljure (only functional language i have tried yet) but i can compile anything longer than one line. Are you using the 'repl'? That process can feel very different from some styles of Clojure development. im using Coljure Box but im very confused as to how i am supposed to write code that dose more than one thing. basically how do i save files, compile them, then run them? Clojure Box likely has a specific process that it advocates since it uses ... clojure-mode and Slime, plus all the power of Emacs under the hood. While this development process works for some (most?) it doesn't work so well for others. I've documented one way of developing using Ant[1] and a certain folder structure... which was OK for a while but I've since switched to leiningen[2]. In the end all you _really_ need is to find a process that fits how you're used to working. You can refer to the 'Getting Started' page on the Assembla Wiki[3].

Let usage question
Hey, I'm parsing a file with a chain of filter and map operations. To make it a little more readable (to me), I put the steps in a let like this: (defn parse-dictionary [reader] (let [lines(read-lines reader) trimmed (map #(.trim %1) lines) filtered (filter is-dictionary-entry? trimmed)] (map parse-entry filtered))) Is this style of let considered good/bad stylistically? Are there technical tradeoffs between this and a bunch of nested forms? Thanks! Dave -- You received this message because you are subscribed to the Google Groups Clojure group.
