When I use Agents for logging I have a different behavior in the REPL as in the program

Re: New release of Paredit mode for Vim with support for VimClojure repls and Map literals

I didn't know that support had been added to paredit mode! When I googled for better Clojure support, I didn't see that one. The differences between Kovac's Nov 2011 version and mine is only that mine applies the mode to VimClojure REPL buffers. I haven't checked to see whether he treats {} the sa

any advice for translating the book "The Joy of Clojure"?

Hi, all. I am new to Clojure and feel exciting playing with it. Recently, I read the book "The Joy of Clojure", and got a strong feeling toward translating the book from English to Chinese, to introduce Clojure to more programmers in China. Actually I am working now. However, though having some e

Re: When I use Agents for logging I have a different behavior in the REPL as in the program

Just a quick guess after a quick glimpse at the code you linked: (map #(send % a-day-in-the-life-agent-fn) domiciles) map is lazy. It doesn't execute anything until you request the result. (do ... (map ...) (foo)) discards the result of map, making it a no-op. This also explains why it works in

Re: Macros to help writing closures?

Thanks Cedric - that's very nice. I'm beginning to understand the power of macros. I have to say they are not very well explained in the clojure docs. In particular, how many distinct 'macro operators' are there, and what are their precise definitions? For instance, is ~' a single operator, or is

Re: Macros to help writing closures?

~' is two operators. 'x is the same as (quote x) ~'x has the effect of not namespacing the symbol when it expands. You can use this technique to create symbols with known names (rather than random autogensymed symbols) that you can use inside your macro. -- You received this message because you

Re: Macros to help writing closures?

I often write functions like this: (defn foobar [] (let [log (makeLogger "foobar")] blah blah )) where makeLogger returns a logging function that prefixes all messages with the name provided. It looks as though macros don't have a "stringize" ability (like the C preprocessor) so tha

Not sure what you want to obtain, but consider this example (defmacro foo [fn-name] `(defn ~fn-name [] ~(str fn-name))) (foo some-name) ; This will define a function some-name, which returns it's name as a string "some-name" понедельник, 23 апреля 2012 г., 1:42:26 UTC+4 пользователь timc н

Re: Macros to help writing closures?

Regarding learning about macros: I suspect that most within the community are relying on existing knowledge of writing macros in Common Lisp or relying on documentation for Common Lisp. I highly recommend reading Paul Graham's _On Lisp_. http://paulgraham.com/onlisp.html Ken On Sun, Apr 22, 20

Re: StackOverflowError caused by apply-template

I think that falls under the heading of "don't do that." :) clojure.template (which I wrote) wasn't a great idea to begin with. It was slightly useful in clojure.test, but I haven't found a use for it since. -S On Sunday, April 22, 2012 8:02:45 AM UTC-4, Shogo Ohta wrote: > > Hi, > > I've run

Re: Help with #'

Hi Dave, If you write (run-jetty routes ...) then the current value of "routes" is looked-up and passed to run-jetty. You won't see any change if you subsequently redefine "routes", because the original definition is what was passed to run-jetty. On the other hand, (run-jetty #'routes ...)

I don't think the book is an open source one, so you should have to find a publisher in China first. And ask them to contact Manning for the importing details. On Apr 23, 2012 1:59 AM, "Zhitong He" wrote: > BTW, is there any way to get the book's source code (latex or other)? > so that I can do
