Heart felt thanks to everyone who contributed to this. I hope to catch up with my lack of JS skills through ClojureScript :) Everything about ClojureScript is exciting stuff.

Re: Literate Programming in Emacs?
I found [1] from Eric Schulte which says to add certain package archives

clojure code evaluates)

Re: Struggling in making a sub-process work in an interactive way
Hi, In Java you would do it with common-exec: http://commons.apache.org/exec/ So add the deps to your project.clj : :dependencies [[org.apache.commons/commons-exec "1.1"]] And use Clojure's Java interop. Keep us posted, I will need to do the same thing soon :) Denis On Wed, Jan 11, 2012 at 4:05 AM, jaime wrote: > I didn't read your code carefully yet but I think you're meaning to > copy streams between my Clojure code and the sub-process, actually > I've tried this but this is probably not what I want. > I might not make myself clear.

ClojureScript One and remote development
I ran into an issue with remote development and ClojureScript One and thought I'd share with others who potentially will run into the same issue. If I want to access ClojureScript One on ComputerA from ComputerB then I have to tunnel or port forward my request to ComputerA's localhost:8080. That's pretty self-evident. However, I couldn't get (cljs-repl) stuff to live update. Instead the repl prompt would hang and I nothing would change in my browser. It turns out the long poll XHR request runs over port 9000 so you need to forward or tunnel both 8080 and 9000 for everything to be happy. This can be accomplished, e.g, with the following from ComputerB: ssh -N -L localhost:8080:localhost:8080 -L localhost:9000:localhost:9000 user@computera - Ryan -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: ClojureScript One - Getting Started with ClojureScript
We cannot share that information because it was a client project. It wasn't really a translation process. We simply attempted to solve the same problem with different tools.

This can also be solved by not hard-coding "localhost" in one.sample.core as it is now. There are functions in goog.uri.utils to help with this. This is on our list of things to do.

Re: ClojureScript One - Getting Started with ClojureScript
Apparently I had Jenkins listening on port 8080. I can now see the CLJS1 application. Will look at the jline problem later. Thanks Brenton.

Is this a bug? extending protocol on js/Object
code is below.
Basically - if I extend a protocol on js/Object then I get an error when
calling map on a map with integer keys.
Is this a bug or an error on my part?
Cheers
Dave
Results first:
If the extend-protocol and call to 'fred' is commented, ths console shows
"START"
"one"
([2 1])
"two"
"three"
([:2 1])
"four"
"five"
([2 1])
"done"
If the extend-protocol and call to 'fred' is uncommented I get:
"START"
"one"
([2 1])
"two"
"three"
([:2 1])
"four"
Uncaught Error: No protocol method ISeqable.-seq defined for type boolean:

Re: Struggling in making a sub-process work in an interactive way
Well actually I also tried commons-exec but it's the same as clojure.java.shell - they run system command directly, after execution they return and terminate.

You should never extend js/Object.

Re: Literate Programming in Emacs?
Eric asks: The only function ob-clojure uses from swank-clojure is `swank:interactive-eval-region' (used with `slime-eval') in the `org-babel-execute:clojure' function. Which function would now be used to evaluate a region of clojure code? Would `slime-eval-region' suffice? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
