Dear all,
Is there a way to wait for all agents to be up-to-date without using await ?
I am in a specific case with a lot of agents and I want all of them to
have finished their work,
and only a few of them had initially work to do.
It is quite wasteful to explicitly await for N agents when on

Which does not seem right, in some way...

Is the thread which creates the agent calls the thread which will wait for
the agents being up to date at the end
I have a complex dependency graph between the used agents, so it is
difficult to compute the p-agent I want.
(They are actually launched by watchers on the agents itself.)
After thought, agents may not be what I need. I may try to use
Fork/Join instead...

n00b questions :)
1. How do I create a function and/or a macro that accepts an unbound
name and interprets that name as a symbol?
example:
(defn perpetuate [name & args]
(do-stuff-with name args)
(println name))
=> (perpetuate world arg1 arg2)
world
this may seem silly or non-idiomatic, b

You're correct - my apologies. I didn't want into get into the why of
things when I really was just hoping for a yes/no kind of answer with
some history had there been any.

Correct. In your example:

Hello everybody,
I remember that the key reasoning for not supporting currying in clojure
was to be able to have variable number of arg functions.. So, I just thought
a bit and realized that it should be possible to do that for fixed arity
functions .. and then wrote the following macro to define
Lol.You're correct - it's so easy i don't know why I didn't see it.
I'm somewhat new to macros.
That said - I thought my question was clearly stated:
How do I create a function and/or a macro that accepts an unbound
name and interprets that name as a symbol?

Hi Sunil,
This is already possible using `partial' function in clojure core, which
also works for variable arity functions, e.g.
(map (partial reduce +) [[1 2 3 4] [5 6 7 8]])

I just pushed out a new release of Logos, my implementation of miniKanren.
At this point it's now pretty original, v0.1's goal and goal constructor
code was mostly a port. Because of that it suffered as the original
implementation assumed TCO. I rewrote that portion of the code from scratch
to use
Hi Eric,
I do know about partial. But what I am saying is that the extra function,
partial, is not necessary if the function was created with
def-curry-fn... The function automatically returns a curried version
when called with fewer number of arguments than necessary like it
happens in ha

I think your work is a wonderful idea. I've been wanting to do this
myself for some time.
Thanks for actually doing it instead of just thinking about it.
I have some humble thoughts/suggestions after reading your code; I'd
love to hear what you think about these points:
1. I think that auto-curr
Hi,
I have a couple of questions.
If I start listing an infinite sequence in the repl and the press ctrl-c, I
always exit to bash. Is there a way to interrupt without exiting the repl?
Is there a way to activate word completion in the repl? I find myself
hitting tab all the time...
I use the
You can execute
(set! *print-length* 20)
to avoid traps with printing infinite data structures.
I'd also highly recommend the emacs/swank combo for your repl. It's
got tab completion and a lot more.
try http://riddell.us/ClojureSwankLeiningenWithEmacsOnLinux.html
to learn how to get started with
Thanks for the quick reply! I tried to get used to emacs a few years ago
with little success. But I'm going to give it another try.
