Re: Advice on introducing a Java dev to Clojure

Johanna, I noticed you mentioned CQRS. In my work, we use CQRS heavily, specifically the Axon framework for Java (utilizing Spring and Hibernate). I got into Clojure through watching Rich Hickey's talks and figured that any language that he wrote had to be good. It's remarkable to me how clean

Re: Advice on introducing a Java dev to Clojure

My latest project uses a CQRS and event sourcing design and the power it gives, coupled with Clojure is just fantastic. Hydrating an object becomes (merge {} (event-store/load ar-id)) - just fantastic. I too find a lot of sympathy between CQRS, event sourcing, FRP and Clojure which I keep meani

2 way transform in single definition ? unification ?

Guys, I have an external and an internal data representation. I need to define transforms both ways. Both models are structured. A pair of in/out functions might look like: (fn [{{b :b c c:} :a}] [b [c]]) (fn [[b [c]] {:a {:b b :c c}}) I just typed that OTTOMH so please forgive any mistakes.

How do I expand a variable that I pass to a macro?

Here is what I'm trying to do: --- ;; route defined outside of the defroutes macro (def foo-route ["/" {:get foo-handler}]) (defroutes routes [[["/" ;; I'm trying to do this, but it does NOT work ["/foo" foo-route] ;; this does work ["/bar" ["/" {:get bar-handler}]]]

Deprecation library

Is there a library out there for deprecating functions? I'm looking for something that prints a deprecation message, but only once, allows deprecation messages to be turned off (probably from environment variable), and perhaps allows something other than `println` to be plugged in as the messag

On Mac OS X (Yosemite) and Linux (Ubuntu), this code works well (I'm using en_US.UTF-8 as charset and encoding for my system). I suspect that the OS (Windows) or its configuration is the source of the problem. On Sunday, July 12, 2015 at 10:57:59 AM UTC+9, Denis Fuenzalida wrote: > > I was abl

Re: clojure don't support .clj source code file by utf-8.

Hi, IIRC Windows requires UTF-8 encoded files to have the BOM (Byte Order Mark). Can you verify that your file has the BOM? Regards, BG On Thu, Jul 9, 2015 at 8:03 AM, Alex Woods wrote: > clojure don't support .clj source code file by utf-8. > it's ok when the .clj source code files by ascii >

Re: clojure don't support .clj source code file by utf-8.

I followed steps described by Denis Fuenzalida in my Windows 7 machine and I can completely reproduce the results. So, in Windows 7, the solution is the .clj files must be saved with UTF-8 without BOM encoding. On Sunday, 12 July 2015 08:57:59 UTC+7, Denis Fuenzalida wrote: > > I was able to re

Re: How do I expand a variable that I pass to a macro?

First of all, I'm pretty sure compojure will let you do the thing, because it's less macro-heavy than what you're using. But to answer the general question, this is a fundamental problem with macros. Once you're making heavy use of macros you start having to write more macros in order to compose t

Re: How do I expand a variable that I pass to a macro?

Simple macros are often sugar around functions. In Pedestal, defroutes appears to be defined as: (defmacro defroutes [name route-spec] `(def ~name (expand-routes (quote ~route-spec So you could use expand-routes and syntax quotes instead. - James On 12 July 2015 at 20:40, Lynn Dylan Hurle

Re: clojure don't support .clj source code file by utf-8.

Of course not. My files do not have BOM. So the problem lies in the BOM thingy? On Mon, Jul 13, 2015 at 10:07 AM Baishampayan Ghose wrote: > Hi, > > IIRC Windows requires UTF-8 encoded files to have the BOM (Byte Order > Mark). > Can you verify that your file has the BOM? > > Regards, > BG > > O
