{ANN} defun: A beautiful macro to define clojure functions with pattern match.

Hi , i am pleased to introduce defun : a beautiful macro to define clojure functions with pattern match. Some examples: (defun say-hi ([:dennis] "Hi,good morning, dennis.") ([:catty] "Hi, catty, what time is it?") ([:green] "Hi,green, what a good day

Re: Schrodinger's cat in clojure?

Thanks Stu & Lee, I will be more careful next time I order a cocktail in a bar. I wasn't aware that pr-str depended on *out*, as it could be implemented as a pure function, without this harmful mixing effect. I guess pr-str is used to get something in edn-shape without (yet) going to the none-

Designing API for a Markov Model

Hi all, I'm new to Clojure and implementing a Markov Model as part of a larger project. I'd like some advice on the API for a progress-state function. I see two possible options. In the first option, we always ask the user to provide and keep track of the MSM state themselves: (progress-stat

Re: jetty restart failing

I forgot to post before, here is the actual error: BindException Address already in use sun.nio.ch.Net.bind0 (Net.java:-2) Also, adding a (Thread/sleep 1000) seems to increase the success rate, but would be nice to be able to really wait on Jetty to shutdown instead of using arbitrary sleep. Th

Re: Schrodinger's cat in clojure?

A man walks into a bar and says "I used lazy evaluation and things were confusing." Bartender says "You might have mixed it with I/O, but then again maybe you're getting tripped up by other some other not-purely-functional aspect of your program or the JVM, like GC or thread transitions." Ok

Re: Schrodinger's cat in clojure?

A man walks into a bar and says "I used lazy evaluation and things were confusing." Bartender says "You mixed it with I/O" without bothering to look at the code. :-) Your experiment uses pr-str, which uses a dynamically scoped resource *out* in order to create its result. Your observation uses p

Schrodinger's cat in clojure?

By watching (println) the experiment we influence the outcome. Is the Schrodinger's cat present in Clojure? This example program that shows how printing a value can change the value under specific circumstances. It seems the case that it has to do with the lazy evaluation that happen in Clojure

Re: Is Transit / core.async suitable for remote function invocation?

Sente works really well, I am using it in the Clojure rewrite of an application and I am using it to call functions on the server from the client by putting messages on core.async channels. I am even using it to get around the current limitation on the ClojureScript side that there's no *pprint

Thank you. BTW, I really liked Clojure/West video editing style. Andy On Fri, Sep 12, 2014 at 8:55 AM, John Gabriele wrote: > A format I particularly like is when there's simply one video file where: > > * the main portion of the window shows the slides, > * a small thumbnail-size portion s
