 At work, I actually have a project.clj with Clojure 1.3.0 in the
 dependencies, and a Clojure 1.2.1 in the dev-dependencies to make
 Leiningen work.

The best thing to do here is to keep the Leiningen plugin in its own
project that runs inside the Leiningen process. Then when you need to
run code in the project itself, use eval-in-project. That way you
don't have to worry about Clojure version mismatches.

Re: Drift 1.4.0 released.

2011-11-27 Thread Edmund 
Sadly, there is no improvement.  I've made a minimal project to
demonstrate.  Literally

- lein new tdrift
- modify project.clj
- add migration-config.clj
- add appropriate migration directory
- lein deps
- lein create-migration

I've put it up on github (https://github.com/ejackson/tdrift).
Perhaps if we can git it to work we can get to the bottom of this ?

Thank for the help here,

 Edmund

 Your new migrate-config should look something like:

My guess would be a clojure version mismatch, based on the stacktrace. 
 Have you tried changing your project to use clojure 1.2.1?

Re: Drift 1.4.0 released.

2011-11-26 Thread Matt 
It looks like a bug in Drift. Try adding an init function which takes
one argument but doesn't do anything.

Your new migrate-config should look something like:

(defn migrate-config []
   {:init (fn [_] )
:directory /db/migrations
:current-version db-version
:update-version update-db-version})

Let me know if that does the trick and I'll fix the bug in Drift.

[ANN] Drift 1.4.0 released.

2011-11-24 Thread Matt 
Drift is a Rails like migration library for Clojure.

I've recently released version 1.4.0 of Drift which includes:

A new Java interface. You can now run Drift migrations, find out the
database version, or determine the highest migration number from java.

User generated migration numbers and time stamp migration numbers. You
can now create your own migration number generator or use one of the
ones included with Drift. By default, Drift will now create the
migration number from the current time. You can still use the old
incremental migration number generator if you want.

You can find the code for Drift on Github: http://github.com/macourtney/drift

Drift on Clojars: http://clojars.org/drift
