Hi, I'm new to Clojure (and Lisp-type languages in general) and I've never used Java... in short, I have a steep learning curve littered with rocks and nails. I also don't know whether it's a good thing that I have long experience with Python and C :-P
In any case, as a first project, I'm trying to add PostgreSQL support to Clogger (http://github.com/Ejhfast/Clogger/tree/master) and I've managed to get it working. *But*, the number of changes involved suggest that I should put the existing MySQL code and the new PostgreSQL code into a separate files and pull in the correct one at runtime based on a configuration variable. This is where I'm choking. I've created a global variable *db-adapter* in setup.clj and would like change http://github.com/Ejhfast/Clogger/blob/dce291524ab76796c781f7200207070fefe26648/src/site/database.clj to selectively :use (or :import or whatever) mysql.clj or postgresql.clj based upon the value of *db-adapter*. In turn, mysql.clj and postgresql.clj will contain custom versions of the "db" and "create-blog" code from database.clj (this leads to a second issue, but I'll save that for later). What I've tried (no laughing!) is this bit of code: (ns site.database (:use [compojure]) (:use [clojure.contrib.sql]) (:use [site.setup]) (if (= *db-adapter* "mysql") (:use [site.adapters.mysql :as adapter])) (if (= *db-adapter* "postgresql") (:use [site.adapters.postgresql :as adapter]))) But this throws an error: java.lang.Exception: No such var: clojure.core/if (database.clj:1) In any case, this code smells funny, even if it were to work. It seems I should be able to somehow build a string such as (str "site.adapters." *db-adapter*) and use that instead (or something else equally concise). And of course, this isn't my only problem. But I'll keep it to one issue at a time.
