I still wonder how it could fare compared to the text base approach we are used to these days. Maybe this is worth an attempt with the current processing power we have at hand and graphic aids that did not exists et the time. I think it could work rather well in an education-oriented environment or in DSLs. I don't think it would be interesting enough to flip mainstream software engineers on its side, unless it had an Apple badge on it. ;-) I'd rather like to see it working in practice - LISP is all about about using and manipulating ASTs, yet s-expressions are somewhat masking this feature (at least to newcomers, which tend to think of the LISP syntax as of a string of characters with some parentheses added to it). Item 2: From what I recall, there were no such confusion in a structural editor. The confusion could still be removed by using proper syntax highlights even in a text base editor. For a graphical/structural representation you'd likely need some sort of meta-data for annotating the source code (e.g. for layout and formatting). These data could then also be used for differentiating between procedure applications and list literals, even if their underlying structures were still the same. In any case, you would not want to change the underlying representation otherwise code that processes code would not work anymore or would become more complex to write. Certainly not in an existing language, unless both representations were perfectly compatible, which is unlikely. As for the macros - that's a valid point. They would have to be redesigned to match against (apply proc ...) forms. I don't think that would have to be any more difficult than it is now, though. A new language would likely come with its own macro framework. Andrzej -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: clojure.io
Whats more, the VM I/O abstraction is already hiding details of its underlying platforms. Having another I/O abstraction across multiple VMs sounds like the Fantom Programming Language approach which pushes a unique API across different VM implementations. AFAIK the Clojure approach is more about accessing more low-level parts of the implementing VM with interop typical to the platform. That being said I would not trade slurp/spit for direct java.io access, for example. I'm afraid I'm expressing myself awkwardly.

3d modeling tools
I'm starting a new project involving 3d modeling and I'd like info on availability of related clojure tools -- and I'd also like to pitch a related tool-building project for anyone who might be interested in working on such a thing. First, I see from github that penumbra is not under active development. Is there a more active project or recommended approach for 3d graphics in clojure? How about for physics (especially physics engines that can make use of large numbers of cores)? How about (especially) something that integrates 3D graphics, a simulation loop architecture, and features like fast neighbor/collision detection? What I'd really love more than anything else would be a version of Jon Klein's breve system (http://www.spiderland.org/breve), or a tool with many of the same features, that makes it really simple to write simulations in clojure. Breve allows coding in its own language (steve) and in python... but it's not being actively developed. I'm not suggesting a project that actually uses breve's code base (although it's open source and that would be possible -- also, Jon was my student and developed breve in part under my funding/direction, and while he has since moved on to other things he's still reachable and helpful) but rather something independent that provides similar functionality in the clojure world. What functionality do I mean? Well, breve provides lots of goodies including trivial installation, a nice GUI for coding and running simulations, painless and pretty 3d graphics, physics, a simulation loop and event handling architecture, fast collision detection, etc. But I could see great value in tools that handled only certain subsets of this. For example I could definitely see forgetting about the coding GUI since that's a whole can of worms being dealt with elsewhere in the community, and also a lot of simulation projects don't need physics. So something that provided just the 3d graphics and a nice way to set up common simulation loops (for example, making it easy and concise to code up the swarm demo in breve) would be great. I'd love pointers to any tools that anyone thinks are relevant, and assuming that there's not already a wonderful integrated tool that I don't know about I'd be happy to correspond/collaborate with anyone who wants to develop one.

In theory, not very difficult. Something like

My argument is that clojure in no way validates the input to (symbol) or (keyword) so why should we call this a bug? IMO, it's the same problem with using Atoms and Refs with pr-str. If an Atom doesn't round-trip through pr-str and the reader, is it somehow invalid? No, it just means you shouldn't use it in cases where you need it to round-trip. The same applies to keywords with unicode characters, or symbols with spaces. That's an apples-to-oranges comparison. Atoms and Refs are identities. Nobody expects identities to round-trip and keep their semantics. On the other hand, Keywords and Symbols are values. Everybody expects values to round-trip and keep their semantics, so when that fails to happen in some instance it violates least surprise. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] clojure-py 0.1.0 Clojure on Python
I'm seeing a RPython test in the examples. Can Clojure-Py emit RPython code from my Clojure code? If so, that'd be really great we could go Clojure - RPython - C - Native I guess it probably isn't since I imagine that laziness uses generators which aren't well supported under RPython but if it did use make RPython code, it'd be really awesome. Well that's the one part where Clojure and Python diverge. Clojure-py does not use Python's generators. This is because Python's generators are mutable. So that actually wont' be a problem. What is a problem though, is the way Clojure-py currently accesses vars. Consider the following: (+ 1 2) In Clojure-py we'd compile this as LOAD_CONST #user/+ LOAD_ATTR deref CALL_FUNCTION 0 LOAD_CONST 1 LOAD_CONST 2 CALL_FUNCTION 2 It's this first line that causes the RPython translator to blow up. Calling LOAD_CONST and supplying a complex type like VAR is more than it can handle. Now it just so happens this is completely acceptable in normal Python code, so that's where the issue is. My plan is to abstract this a bit. I plan on providing global vars that allow the user to specify how the current code is bound. For instance, if #user/+ is a static var, there's no reason to deref it every single time, since it will never change. However, dynamic vars need to be deref'ed, and RPython vars need to use pure LOAD_GLOBAL, LOAD_ATTR calls. The plan then is to provide the Clojure-py backend with a simple (deref this var) object that will allow the compiler to on-the-fly decide how certain pieces of code are called. It just so happens that once this is implemented, it will also allow us to serialize clojure code using CPickle. This should allow us to drop the startup times of Clojure-py down into the 1sec range. And actually, being able to run Clojure code on RPython is a personal goal for me. It's probably one of the biggest motivations for me to actually start this project. So as I find time, I do plan on exploring this, and building up a good macro/function library to allow users to experiment with RPython a bit more easily.

Re: proper clojure hammocks/alternatives
Ah, thanks! I will look into all these things.

It's a good way to toss away all the non significant things I had to deal with at work. It allows me a second work shift at night to put all the nice ideas that popped out together.

[ANN] jark 0.4.0
I am pleased to announce the release of jark v0.4.0. So why another Clojure tool ? Problem Startup time of the JVM is slow and therefore the command-line applications running on it are slow as well. There are tools like Nailgun that partly solve the problem. However, there isn't a tool that is Clojure-aware, lightweight, secure and extensible. Solution * Implement a client/server system that uses a protocol such as nREPL to communicate Clojure data structures over the wire * Build a client that is extremely lightweight and has minimum runtime dependencies * Provide a server-side framework to interact with the JVM Runtime Jark is one such tool that helps run clojure programs on the JVM, interactively and remotely using the nREPL protocol. It has 2 components - a client written in OCaml and a server written in Clojure/Java. The client is compiled to native code and is extremely tiny (~200KB). Here are some features: http://icylisper.in/jark/features.html See http://icylisper.in/jark/started.html to get started. Catch us on #jark on irc.freenode.net Mailing list: https://groups.google.com/group/clojure-jark Project page: http://icylisper.in/jark Caveats --- 1. The current jark version still uses nREPL 0.0.5. However, We are currently working on jark 0.5.0 that uses newer implementation of the protocol.That should be out soon. 2. lein plugin / lein2 integration has been moved to 0.5.0 release. Once that plugin is ready, it should help run lein interactively. 3. The Windows client binary has not been completely tested yet. Hopefully we will have a test-suite in place for the client. 4. REPL does not work on windows yet. THANKS to: * Martin DeMello, co-author of jark * Lucas Stadler * Abhijith Gopal * Chas Emerick (for nREPL) Happy Hacking. Go ahead and give it a try! -- isaac -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: How to escape a space in a keyword?
This is my last reply for this thread as the support for improved doc strings for symbol and keyword has been kind of underwhelming - which is fine - time to move on. (besides, now I personally know more than enough about the implementation of those functions to use them conformantly ;-) ) Surely undocumented behavior is undefined behavior by definition? True - but that kind of assumes that there is documented behavior… the one-liner for (symbol ns name) doesn't say anything about input parameter value types, and leaves the valid characters set upto the user knowing where to find it on the http://clojure.org/reader; page. Note that I had to find the valid types for [name] and [ns name] by looking thru the clojure.core cljjava code. ...unless explicitly documented to the contrary (e.g., when given invalid input, this function shall throw an exception). It took me about 3 minutes to scan thru the API list and testing at the repl to find alias, bases and bound? - all throwing exceptions while it is not mentioned in their docs. I'm sure you could have found many more in the same time before you wrote your reply - not sure what that tells you (?). Also not sure what the big issue is to help the (novice) users out by being explicit in the doc-string about the contract and behaviour of a function. As far as I can tell, you have functions that validate and barf, validate and return some well-known value like nil for invalid input, and you have the garbage-in, garbage-out type. Unless you can guarantee that the first two types are always clearly identified in their docs, you can leave the last one open… however, why not mention it also explicitly? Especially for symbol, which is a pretty key entity for the clojure language. We have a one-liner, low on content for symbol/keyword and a page-long doc for deftype/defprotocol. So one last time… instead of having the current docs: clojure.core/symbol ([name] [ns name]) Returns a Symbol with the given namespace and name. clojure.core/keyword ([name] [ns name]) Returns a Keyword with the given namespace and name. Do not use : in the keyword strings, it will be added automatically. My suggested docs are: clojure.core/symbol ([name] [ns name]) Returns a Symbol with the given namespace and name. (symbol name): name can be string or symbol. (symbol ns name): ns and name must both be string. A symbol string, begins with a non-numeric character and can contain alphanumeric characters and *, +, !, -, _, and ?. (see http://clojure.org/reader; for details). Note that function does not validate input strings for ns and name, and may return improper symbols with undefined behavior for non-conformant ns and name. clojure.core/keyword ([name] [ns name]) Returns a Keyword with the given namespace and name. Do not use : in the keyword strings, it will be added automatically. (keyword name): name can be string, symbol or keyword. (keyword ns name): ns and name must both be string. A keyword string, like a symbol, begins with a non-numeric character and can contain alphanumeric characters and *, +, !, -, _, and ?. (see http://clojure.org/reader; for details). Note that function does not validate input strings for ns and name, and may return improper keywords with undefined behavior for non-conformant ns and name. Take it or leave it.

That's certainly the approach taken by many programming language standards.
