Debugging with Cider
Hi all, Has anyone gotten debugging in emacs working with cider (was nrepl). I did fork and update cljdb but it is pretty old school. https://github.com/m0smith/cljdb Is there any work on ritz or cdt?

This works as expected.

Should I be able to call generate-id in map literal?

This also fails:
{ (gensym) foo

From the stack trace I get it looks like the reader macro that handles map
literals is only looking at the function call, not the result of the
function call. This makes sense as it is the reader, not the evaluator.

Smith m0sm...@gmail.com wrote: There is a mismatch between hibernate maps and clojure maps which means that there is some translating between them. Hopefully, this will be smoothed over in the future What is the mismatch? The mismatch is that Hibernate and Clojure see Map object differently so there is an (in my mind) unnecessary conversion that has to take place at the boundary between the two systems both in sending data to Hibernate and also retrieving it. It is not a huge deal, but it is annoying. As an example consider this code. Rather than treating a map as Clojure map (immutable), the develop has to treat the map as a mutable object. (with-session [session _] (let [person (.load session Person 1) email topo...@topoged.com] (doto (. person (get emailAddresses)) (.add email Instead I would like somthing like: (with-session [session _] (let [person (.load session Person 1) email topo...@topoged.com] (assoc-in person [:emailAddresses] email))) But that leaves the question of how to propagate the change back to the Hibernate session.I had thought about some hybrid between java.util.Map and IMap but decided not as it would end up just creating more problems than it solves.

topoged-hibernate: a clojure hibernate library
As part of a larger project, Topoged, I am developing a Hibernate library that makes working with Hibernate from within Clojure much easier IMHO. It uses the standard Hibernate configuration and provides wrappers and whatnot to simplify the interaction. For example, to write a record to the database: (hibernate) ;; Only called once (with-session [session tx] (.save session Event (doto (java.util.HashMap.) (.put title Our very first event!)

Re: topoged-hibernate: a clojure hibernate library
I am working on making library useful to the public: https://github.com/m0smith/topoged-hibernate One question I would like a comment on: I have been using entity-maps rather than POJOs because it makes for a cleaner interop with Clojure. The amount of code needed goes way down while the standard POJO makes for a lot of code. Do you see a need to do a lot of work to support POJOs?
