Clojure compiletime vs runtime

Is there an explanation of how clojure deals with scoping and its static checking. It seems to be a hybrid of a static language and a dynamic language when it comes to compilation. I'll elaborate. The following code wont compile: (defn x [] nil) (defn y[]) ((x)) however this code will compile:

Re: Puppet Labs and Trapperkeeper

Great timing on the new blog post. I'm ramping up on my first "real" clojure app, and have been planning to use Component for this piece. I read the first blog post yesterday and it sounded interesting, but I've pretty much locked down the stack I'm going to use (you can evaluate libraries for

Re: Annotations on gen-class :state

Alex, what's your feeling about how a reify-like form and a deftype-like form that supported concrete class extension (as detailed in the other thread) would be received? If you think there might be interest I can start a proposal and possibly write the patch as well. On 15 April 2014 14:32, Alex

Re: Annotations on gen-class :state

It is a non-goal for gen-class (and reify, proxy, etc)to support the construction of any possible Java class or to fully support every possible Java feature. That said, particular extensions to existing features might be useful in reasonable use cases. On Monday, April 14, 2014 7:56:21 PM UTC-

Re: Extending a data model

An update, I read about protocols and multimethods. I think multimethods are a decent way to go (cant use protocols without a defrecord) provided they work across namespaces. On Tuesday, April 15, 2014 11:52:36 AM UTC+12, Andrew Chambers wrote: > > Hi everyone, > > I'm new to clojure and in or

Re: Extending a data model

Thanks for the tip, I think multimethods may be what i need in this case (perhaps which checks the current architecture in the dispatch function so i can disable some). I want to avoid having to pass an object around and extract methods (simply because it clutters my code). Dynamically binding

Re: Annotations on gen-class :state

Well, I'm a bit torn on this one. On the one hand, I'd love to have something that meets my particular use case (of course!) which I wrote about here: https://groups.google.com/d/topic/clojure/MznBwxZt4cY/discussion. I think that case can be met while still keeping the API fairly simple. But once y

Hey Andrew, I actually built something very much along these lines a few months ago if you care to cheat off of it: http://github.com/arrdem/toothpick is an assembler generator system that works more or less along these lines. Label support is still a problem I haven't completely solved and I n

Re: Linked Hash Map/Set

I don't have time right now to look at the details of your implementation, but can answer at least one of your questions. Clojure's normal PersistentHashMap data structure does create a new object for every key you remove (with dissoc), add, or modify the value for (with assoc). So if a single as

Linked Hash Map/Set

I'm on a mission to implement an ordered map and set structure for Clojure. Much like LinkedHashMap for Java but as a persistent data structure. The idea is that instead of saving a simple [k v] MapEntry we can save [k v left-node-key right-node-key] plus a global head-node-key to walk through t

Re: Annotations on gen-class :state

This is unfortunate. I certainly can write a Java class and I expected that would be the answer. The question for me is whether, as a group, we see any value in having a consistent interface with the JVM. One could argue that Clojure does not need any of the interop features it already has.

Re: Annotations on gen-class :state

gen-class really isn't suitable for doing complicated interop like annotating fields. It's heavily oriented towards a single means of managing state, which is a single field generally containing an atom, which in turn contains your actual state in a map or similar. If you really need multiple field
