Re: Registering commands in a command language
You can do this using multimethods. defmulti and defmethod will allow you
to do everything you ask for apart from adding a doc-string to each
command. Have a look at:

I'm learning Clojure, and part of the project I'm making is a command
language: the user can type commands at the application in something like a
REPL, and have a dialog with the application. I want to dispatch to a
function that carries out the command based on the first word of the
command; the function then receives the remaining words in the command, and
can do with them what it likes. So I'm going to need a map, something like
{ dothis #'commands/dothis, dothat #'commands/dothat ...}
The question is, how best to build up that map? I'd like to define a
command like this:
(command dothis
Documentation string
[argv]
)
and have (command) define the function and add the entry to the map.
I can think of all kinds of ways to do this. I could define
(def command-map {})
and then have (command) rebind it:
...
(def command-map (assoc command-map name function))
but I know that's frowned upon. I could make command-map contain an atom,
and use (swap!) to update the atom, but really, the mapping isn't going to
change at run-time. I could make (command) a macro, so that it's really
updating command-map at the top-level, but that seems cheesy.
Or, I could make (command) define the function as a public function in the
'commands namespace, which would be reserved for that purpose, and attach
the command name, e.g., dothis to the function as metadata. Then I could
build the map by querying the namespace using (ns-publics).
Is there is a normal way to do this kind of thing?

Strange update-in Behavior
I am not sure if this is considered a bug or if it is simply expected
behavior, so I thought I would ask the list for clarification.
I have this test which passes and shows the strange behavior that I am
encountering:
(deftest update-in-and-remove
;; The leaf value becomes and empty list instead of [1 3]
(is (= {:mykey {:myotherkey '()}}
(update-in {:mykey {:myotherkey [1 2 3]}} [:mykey :myotherkey]
remove #{2})))
;; Forcing a vector results in the behavior that I would expect
(is (= {:mykey {:myotherkey [1 3]}}
(update-in {:mykey {:myotherkey [1 2 3]}} [:mykey :myotherkey]
(comp vec (partial remove #{2}))
I think this behavior is due to the use of apply in the definition of
update-in and I think (but haven't tested) adding a partial to the
non-recursive clause will fix this:
https://github.com/clojure/clojure/blob/master/src/clj/clojure/core.clj#L5687
However, I don't want to submit a fix if this is the expected behavior.
Thoughts?

Re: Strange update-in Behavior
it is expected behavior, because update-in calls the supplied function with
the value it finds in the map as the first argument, so your first call
ends up being
(remove [1 2 3] #{2})
Since ([1 2 3] 2) = 3 and is truthy, the result is ().
In your second case you're using (partial remove #{2}), so the result is
'(1 3), which is then turned into a vector by vec.

This behavior makes a lot more sense now. Thanks for the clarification!

Observing the R community may be insightful for the Clojure community with respect to the Incanter project and other data science oriented efforts in Clojure. Ditto for Julia. JuliaCon 2014 http://juliacon.org/ will be in Chicago in June. Any other Clojurites going? I'm mainly interested in Clojure, mainly because it's hard to beat it as a data integration language (whatever that means), but I think Julia is worth a hard look. -Gregg There is also the newish book Clojure Data Analysis Cookbook (Packt, March 2013) by Eric Rochester [1]. I haven't read it but it covers things like working with R, Mathematica, and Inchanter via Clojure.

Confusion about binding *ns* before defining a var
I went to write a context macro so that I could define functions in another namespace. After the obligatory googling, I found with-ns: http://richhickey.github.io/clojure-contrib/with-ns-api.html Clicking through to look at the source, I was surprised to see that eval was being wrapped around each form in the body of binding. I thought, surely forms within the body of a binding expression are evaluated in a context of the bindings?!: user (ns blah) nil blah (in-ns 'user) #Namespace user user (binding [*ns* (the-ns 'blah)] *ns*) #Namespace blah Okay, no surprise there. Yet, to my surprise: user (binding [*ns* (the-ns 'blah)] (defn foo [])) #'user/foo user (binding [*ns* (the-ns 'blah)] (eval '(defn foo []))) #'blah/foo The extra eval is necessary after all. But wait, what does the one without eval expand into? user (clojure.walk/macroexpand-all '(binding [*ns* (the-ns 'blah)] (defn foo []))) (let* [] (clojure.core/push-thread-bindings (clojure.core/hash-map #'*ns* (the-ns 'blah))) (try (def foo (fn* ([]))) (finally (clojure.core/pop-thread-bindings Huh. Alright, let's remind ourselves of what def means: user (doc def) - def (def symbol doc-string? init?) Special Form Creates and interns a global var with the name of symbol *in the current namespace (*ns*) *or locates such a var if it already exists. If init is supplied, it is evaluated, and the root binding of the var is set to the resulting value. If init is not supplied, the root binding of the var is unaffected. Please see http://clojure.org/special_forms#def Now my confusion: isn't binding *ns* exactly how one sets the current namespace? It seems like def is not behaving as advertised. I looked briefly at jvm.clojure.lang.Compiler.DefExpr, but I wasn't able to figure out why the symbol and namespace resolution going on in that class didn't consult thread-bindings (by design?). Assuming this isn't a bug, what's the rationale for the current behavior? -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: ANN: [prismatic/plumbing 0.3.0] release adds ClojureScript support
Prismatic responded via twitter. Funny thing is, whoever's writing those tweets seems to think her (or his) audience would simply buy insincere apologies like we didn't intent and so clueless to who she's talking to that she would mention the unsubscribe link. See: https://twitter.com/muhuk/status/471822897791516672 Opt-out only might be OK with non-technical users, it's debatable. But the only valid form for mass mailing is opt-in for technical users. And I think we should speak up. If not for ourselves, we should speak up because Prismatic is a part of Clojure community.

For a def form, it's the ns that is current when the form is compiled that determines in which namespace the resulting var is created. In the first case, the defn form is compiled before the binding to (the-ns 'blah) is in effect. In the second case, the defn form is quoted and remains unevaluated while the binding form is compiled. While executing the compiled code for the binding form, eval compiles the defn form (and then executes its compiled code). In this case, the defn is compiled after the binding to (the-ns 'blah) is in effect. --Steve -- You received this message because you are subscribed to the Google Groups Clojure group.

It's exactly this point that's confusing. The defn form expands into a def, whose documentation says it uses the current namespace. The current namespace, as I understand it, is what's bound to *ns* which IIUC should have been accomplished with the binding macro. The first code snippet was meant to demonstrate that. Here's another variant in case there's confusing about *ns* being lexical: user (defn println-ns [] *ns*) #'user/println-ns user (binding [*ns* (the-ns 'blah)] (println-ns)) #Namespace blah I don't see the reason why def should behave as it currently does; it seems like it should lookup the current thread-binding for *ns*, making the second case's use of eval unnecessary. Since it doesn't, I'd like to know why it couldn't (or shouldn't) do the thing that seems more intuitive. That said, if the special form let* does not evaluate its arguments in left to right order such that let* actually evaluates def's before anything else, then I would understand why the current behavior is the way it is. However, then I'd just be curious about let*... -- You received this message because you are subscribed to the Google Groups Clojure group.

help with the lawyers?

Re: help with the lawyers?
This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. This is a very peculiar clause for me. I have just checked GPL text and it doesn't contain anything like that. I'll look into this further later, but at this point I'm concerned by a license that is in a way limited to a geographical location. A location which I don't live.
