Re: Lambda: A lniux distro for clojurists
Great idea. But this be implemented as a pallet or vagrant script instead of a ready-made VM?

One thing that seems missing, however, is a single unified way of setting up the clojure environment. Which seemed pretty daunting to me at first. So I have decided to create a Linux Distro specifically for Clojure development. I have been bouncing this idea in #clojure and it got a good response. So now I have started the complete development effort. My plan so far is as follows. Mission Statement for the Distro The distro should be able to: - Connect to internet. - Be able to convert itself into An VM/Iso/LiveCD etc - Have all IDEs for Clojure installed and preconfigured. - Eclipse - Vim - Emacs - Netbeans - Have a ready to play connection to clojure forums and channels - Have at-least one book on clojure programming on board - Have following clojure specific features - It should have leiningen installed and configured - It should have a local repo of all current clojure plugins - It should have a local cloud on which you can deploy web apps easily - it should have REPLlabs on baord and configured - Have Clojure specific branding The packages that are needed absolutely: - OpenJDK 1.7.0 - Leiningen - Clojure - Eclipse - Vim - Emacs 24 - Netbeans - Emacs Starter kit - CCW plugin for eclipse - Firefox/Chrome - A local webserver - Postgresql - LXDE/XFCE - Gwibber/Other Social network Client - xchat - irssi - git - Regular packages for system functioning. I am still open to ideas. I intend to roll it as a complete distro, so I will love any and all input. For now, the specific things I need input for are: - Who/How to create the art for branding. - Any packages that are missing from the above listing. - Any suggestions for the overall functioning. I will soon have an actual website set up. It is my intention to create a fully functional, independent Development environment for Functional programmers by release 2. Right now, I am working on release 0.0.1. Looking forward to all input. regards. banseljaj -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Lack in the documentation
- This Clojure-IDE is actually Eclipse for Clojure (which integrates Clojure, Counterclockwise and lein libraries - not as external tools) Hang on, you were advocating Clojure for non-Java devs, yes? Yet you want to inflict Eclipse on them? I'm only half-joking here. Non-Java developers are going to want to use something lightweight and simple... that's not Eclipse (it's not Emacs either)... not sure what is the best route here (Clooj?). I suggested Eclipse for several reasons: - It is AFAIK an IDE to build IDEs and can be rebranded the way you want. - It is the shortest path to have an IDE instead of starting from scratch. Creating that IDE is a matter of integrating and repackaging since the tools are already there (CCW, lien, test frameworks). - I hope you didn't misunderstand what I said above. I am not against Java and I am aware the Java interop is one of Clojure's strength and eventually you will need an IDE that can deal with both languages and Eclipse is an IDE for both. A simpler IDE, like CLOOJ, might be good for a newcomer but when he has advanced in the language and needs both languages, the simpler IDE will have to provide the tools Eclipse (and VS) currently provide for the host language. That's why I think an Eclipse-based IDE is the better choice for an official IDE. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Lack in the documentation
It is clear that most Clojure documentation (books, tutorials, blog posts) address Java or other language developers. I am at chapter three of the Clojure Programming book and so far I have seen many snippets of Ruby and Python code. That's not necessarily wrong but obviously the book assumes you are a Java, Ruby or Python developer. AFAIK, all Clojure books do. There is no lack of documentation addressed to experienced developers. But there is indeed a lack of documentation that addresses people who are just starting programming? This is because, I suppose, many in the community probably believe that Clojure is not suitable as a first programming language. This has been discussed on the list before and some in the community believe it is and some don't. I, for one, believe that a new developer or a computer science student should be able to go a long way learning Clojure and write applications with Clojure alone without any mention of interop until the very end. Such a book would be useful to anyone whether he is familiar with another programming language or not. However, I think it is more of an advocacy problem that appears as a documentation one. It is as if the community is advocating Clojure only to existing developers. But Clojure is a hard sell to existing developers especially Java developers. It is better to advocate Clojure to new generations of developers, computer science students and professors and even power computer users (like Excel programmers!). These are not served as much with books and tutorials while existing developers are served very well. Why is Clojure hard to sell to Java developers? When Clojurians write about Java it is as if there is a love-hate relationship to Java and they have a conflicting message. First we tell them how bad Java (or their language is): It is fine to hate Java and love the JVM; Java is mutable and uncontrolled mutability is bad; it is imperative; Java's time model is broken and so on. But then after stating all the bad things about Java, we tell these enterprise guys who have invested a lot in Java: wait, you can write Java in Clojure better than in Java. You can still use all the (mutable, imperative) Java you have written over the years in Clojure. But I doubt that enterprise people and developers would do so for many reasons: a) All those concrete things around you look like objects that has properties and actions: this keyboard I am using; that car in the street, that toaster. It is very easy to sell OOP when you explain it starting with the concrete going to the abstract to a new developer and it sounds very natural. Most early examples in OOP books (about cars, people and things) sound immediately natural and practical. It doesn't matter that this model or analogy breaks very soon; the developer will have already been sold on the idea. That's what most existing developers are used to. In contrast, it is hard to think functionally about practical matters and most early examples in functional language books are about numbers and mathematics that are not practical to a new developer. b) Similarly, the imperative style of programming feels more natural as well to a junior developer and very similar to how we do things in life. Algorithms, to them, are just recipes of steps; not mapping, filtering and reducing data structures which sounds mathematical (the horror). Just reference that library; do this, that, then a loop over a collection there and you're done and can go home and sleep all night. Functional programming, on the other hand, is high on the abstraction level from the very beginning; but the average developer doesn't care about high levels of abstraction. At every corner, a newcomer has to change the way he thinks to grok Clojure. Everything is completely different; even adding two numbers (+ 1 2) looks weird to what people are used to. c) It is easier to get used to Java syntax and it reads easily from the beginning. It takes longer time, probably months, and perseverance to get used to reading Clojure code. Try to read aloud some Java code and some Clojure code; the later sounds like reading algebraic equations; the former reads like sentences (albeit missing prepositions, ands and buts..). You scroll pages skimming Java code but you need to ponder for sometime to understand a Clojure function or a macro. It is as if there a hill on the road to learning the two languages; the hill is at the very beginning on the road to Clojure and it is at the end for Java. Iff a newcomer perseveres he will climb the hill and eventually get used to reading Clojure code and will appreciate how pithy it is. He will be shocked when he realizes that all he needs one-page cheat-sheet (for the language and most of its functions) instead of a huge reference for his language syntax and APIs. But that was a very big IF. Clojure is completely different in style, syntax and way of thinking
