Well, ^something still is equivalent to ^{:tag something}, which as I
understand it is useful for compiler typehinting. I just was unaware
that this worked for keywords as well as symbols, though when you
point out that tags were used for custom types this makes more sense.

Re: coming from statically typed oo languages - how do deal with complex objects graphs in clojure?
Have a look at reduce: (reduce conj [] (take 9 (cycle [0]))) take returns a lazy seq. but reduce will return you a vector. Looks like you try to translate as if you were using a language that allows mutations but you use functions to hold values that you redefine since mutation is restricted to refs and atoms. I suggest you look at atoms to hold values if they can mutate globally or at recur if you need to implement some recursion and rebind new values within a function's body. Luc P.

- Nested defns are not good.
why? imo, nested function/method definitions are a tool to fine-tune
accessibility. just like public/private, but much more powerful. why
Right, but defn binds function names at the top-level (which is why
it's considered poor form to nest them - it doesn't create nested
functions). So those functions are actually all public in that
namespace:
user= (defn foo[a] (defn bar[b] (* a b)))
#'user/foo
user= (foo 2)
#'user/bar
user= (bar 3)
6
user= (meta #'user/bar)
{:ns #Namespace user, :name bar, :file NO_SOURCE_PATH, :line 1,
:arglists ([b])}
See how bar is defined when foo is called but it is callable directly
in the user namespace?
Using let or letfn creates locally scoped functions, which is what you want.
again, why? the functions belong there, and nowhere else. they do not
make sense outside the winner-function. they use parameters which are
in scope there. factoring them out would actually make them more
complex since i would have to add more parameters to their signatures.
You can define functions private to your namespace with defn- and you
can define them locally to other forms with let/letfn.

Re: No such var while calling a (:require) 'd function
Hey, thanks for getting back to me. I was hacking away at this at the meantime. I defined 'remove' functions in 2 other places - bkell , commands. I ended up renaming *commands/remove* to *commands/removek*, and now all invocations are working. But I'm pretty sure I'm using namespace and require erroneously. Currently, I have a source file structure like below: src/ bkell.clj src/commands/ add.clj remove.clj etc... But each of the 'src/commands/' clojure files, uses the '*(ns command ...)*' namespace, not '*(ns command.remove ...)*', etc. I wanted to do it this way, so that client code could just call *command/remove*, not * command.remove/remove*. But I'm realising that I should instead define (ns commands) once, and use (in-ns) in other locations. You can see the source here https://github.com/twashing/bkell/tree/jasmine-bdd/src. Looks like 'get' can be redefined in two other namespaces: bkell , commands. But when I try to do that for 'remove', the repl seizes up, and I'm curious to know why.

Figuring out how to integrate clojurescript with other libs
Hello, I really enjoy clojure for back-end work and have been exploring using clojurescript for the front end of an upcoming project. Quickly you run into the issue of integrating external libs. From reading the list and from Rich's cljs rationale, I gather that the best practice is to use google closure whenever applicable. That largely eliminates the need for libraries like jQuery, which is very cool. But(!) there are some libraries I use regularly that are not so easy to replace with closure, like three.js (webgl). My ideal outcome when using these libs would be that I: A.) Retain the ability to compile the cljs portion of my code with :advanced, saving ~200kb (pretty important for production code). B.) Yet somehow maintain integration with these internal libs. In my initial tests this doesn't work out of the box, since :advanced mode mangles any function calls to the external libs. After some research it looks like the answer is externs[1]. However, js projects that maintain an extern file seem to be few and far between, and generating one correctly for a library as large as three.js is daunting. So what are other people doing? Is there another solution to this out there? If not, maybe an extern autogenerator written in clojure would be a good solution. - Jason [1]: http://code.google.com/closure/compiler/docs/api-tutorial3.html -- You received this message because you are subscribed to the Google Groups Clojure group.
