[PATCH] Make clojure.contrib.sql/with-connection return the body result
Hey all, The current version of the (with-connection) macro in clojure- contrib doesn't return the result of its body. (It just returns nil from the commit() call at the end of the transaction).

Re: clojure rant
What is the value of variable swank-clojure-jar-path in emacs? Try to set it by running M-x customize-group swank-clojure , I wonder if it helps. I got it running finally with Matt advice.

Re: clojure rant
Clojure/SLIME integration may be in flux after the recent API changes. But plain old inferior-lisp mode works just fine: M-x customize-variable RET inferior-lisp-program ...set the path of your Clojure startup script... M-x inferior-lisp A simple startup script could be simply: #!/bin/sh exec java -cp clojure.jar:clojure-contrib.jar clojure.lang.Repl Hope this helps, -Stuart On Sep 13, 12:41 am, Alexey Goldin [EMAIL PROTECTED] wrote: How people in this group run clojure?

Re: Clojure Poll 09/2008
What are you doing with Clojure? I'm trying to write a DSL for molecular dynamics analysis (with partial success). Users will be able to compose complex properties from basic info such as bond lengths/angles, position, velocity, etc. I'd like to add regression and integrate it with a 3d viewer eventually. With some modification, this could allow users to generate coordinates for complex structures (i.e. bio stuff like dna). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Clojure group.

clojure.contrib.sql updated
I've made some changes to clojure.contrib.sql: - Renamed some functions/macros to shorter names: get-connection - connection execute-commands - do-commands execute-prepared-statement - do-prepared with-query-results - with-results - Added create-table, drop-table - Fixed a bug in with-connection--a prematurely closed try expression. (It looks like this was accidentally harmless through an interaction with with-open.) - Changed do-commands/do-prepared so they accept a variable number of commands/parameter sets (using a '' argument) rather than an explicit sequence. - moved examples to clojure.contrib.sql.test and updated them to the new API. Comments welcome. --Steve --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Clojure group.

Re: Clojure Poll 09/2008
What are you doing with Clojure? I work in a fairly conservative environment where they probably wouldn't approve of my using a language in an alpha state, much less a variant of Lisp! But since I love the language and the interactive environment with Emacs, I decided it's easier to beg forgiveness than ask permission. 1. Wrote a Clojure service that runs on remote thin clients. It receives Clojure forms that instruct it to download and cache PDF templates, dynamically fill in form data, overlay logos, etc.., then print the resulting PDF. 2. I also use it for prototyping and experimentation. What 3 features would you most like to see added next? 1. I agree that better stack trace/error information would be nice. Not really features, but... 2. More thorough documentation and examples: For instance: how to profile your code and decide where you should use type hints. 3. Can't think of #3. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Clojure group.

The documentation is not well suited for the masses who are not well-versed in Lisp dialects or functional programming. It's more like marketing material for those who have already spent a some quality time in that world, and are curious to see how this new kid on the block compares. I think it does a great job at selling the language to those people, but the newbies are left behind. To help newbies, the documentation needs to be reorganized, more introductory text needs to be written, many more examples need to be shown.
