Just got an email saying Elements of Clojure has been updated and is now fully released! what a good time to buy a copy

Ooh! Given recent discussions I'd like that.

user=> (clojure.string/split "-m edge.main" #"[^\\]\s")
#_=> ["-" "edge.main"]

Oh, I see. It's matching all non-\ characters. This must be a bug in the library.

It's supposed to be providing string escaping afaict.

> The one-jar mechanism already passed command line arguments through to main, I have added a One-Jar-Main-Args manifest argument to allow for default arguments to be provided to main. Whitespaces can be escaped using backslash. Yeah, the regex is just broken 🙂 I guess I get to fix it then

i wonder if i figure it out correctly from memoize source that it doesn't have any limiting on the memory that it uses ?

at least at first sight it seems so

clojure.core/memoize creates an atom containing a map, and can assoc new key/value pairs into it, but never removes anything, yes.

so one has to be reasonably careful when using it .. ok 🙂

Yep, if you need full configureability, use core.memoize / core.cache

I have

public abstract class KeyStoreKeyingDataProvider implements KeyingDataProvider
{
    /**
     * Provides a password to load the keystore.
     */
    public interface KeyStorePasswordProvider
    {
        char[] getPassword();
    }

I tried KeyStoreKeyingDataProvider/KeyStorePasswordProvider but it does not find the class

won't this do ? KeyStoreKeyingDataProvider$KeyStorePasswordProvider

just like java.util.Map$Entry works for the Entry interface in Map

@kulminaator I tried that but it still does not work with proxy

I get

No matching ctor found for class
   xades_signature.core.proxy$java.lang.Object$KeyStoreKeyingDataProvider$KeyEntryPasswordProvider$KeyStoreKeyingDataProvider$KeyStorePasswordProvider$d860b872

This is what I’m trying to do

(defn build-provider [password]
  (proxy [xades4j.providers.impl.KeyStoreKeyingDataProvider$KeyStorePasswordProvider
          xades4j.providers.impl.KeyStoreKeyingDataProvider$KeyEntryPasswordProvider]
      [password]
    (getPassword
      ([] password)
      ([_ _] password))))

@kulminaator ^

I've been away from Clojure for a bit, and I'm trying to switch an app written for 1.7.0 over to 1.9.0. The app has a bit of (unavoidable) nasty Java interop using :gen-class. In 1.7.0 and 1.8.0, I can include this in my ns statement:

(:gen-class ... :methods [[foo [] "[D"]  [bar [] "[Lyow.Double2D"]] ...)

@pvillegas12 i might be misreading this but why is that [password] in proxy declaration there not just [] ? you were talking about an interface but by the sound of the error clojure is looking for a constructor with that argument

my intent is to create a class which implements those two interfaces with password as the only instance variable

is proxy the way to achieve this?

you can make things implement interfaces but that slot there is not for your instance variables, it's arguments for constructor of the first class if it's a class ... and in your case the first thing is an interface

a truly flawed example but perhaps get's my message across

thanks @kulminaator! removing the [password] makes it work 😄

thanks for pointing me in the right direction

ah ok, you figured it out without me adding a hideous example here, great 😄

i was about to copy paste it

😄

Some of that was painfully on point -- and there were some wonderful references to other talks at Conj (did you spot the picture of the flan?). Folks were just dying with laughter... Great humor, wonderfully delivered 🙂

Why do people keep calling me?

@seancorfield I loved it. Honest and hilarious. 🙂

Just watched the REBL talk too, loved to see people looking back at resurrecting Genera. It is time...
