Leiningen
"Leiningen!" he shouted. "You're insane! They're not creatures you can
fight--they're an elemental--an 'act of God!' Ten miles long, two
miles wide--ants, nothing but ants! And every single one of them a
fiend from hell...
-- from Leiningen Versus the Ants by Carl Stephenson
Leiningen is a build tool for Clojure designed to not set your hair on fire.
Install
For now, you will need http://p.hagelb.org/leiningen-deps.tar unpacked in the root and http://p.hagelb.org/lancet.clj on the classpath.
Usage
$ lein deps # install dependencies in lib/
$ lein test [PRED] # run the project's tests, optionally filtered on PRED
$ lein compile # ahead-of-time compile into classes/
$ lein repl # launch a REPL with the project classpath configured
TODO: jar, uberjar, swank, new, help, deploy, pom
Configuration
Place a project.clj file in the project root that looks something like this:
(defproject leiningen
:version "1.0-SNAPSHOT"
:dependencies [["org.clojure" "clojure" "1.1.0-alpha-SNAPSHOT"]
["org.clojure" "clojure-contrib" "1.0-SNAPSHOT"]
["org.clojure" "lancet" "1.0-SNAPSHOT"]
["org.apache.ant" "ant" "1.7.1"]
["org.apache.ant" "ant-launcher" "1.7.1"]
["org.apache.maven" "maven-ant-tasks" "2.0.10"]])
FAQ
Q: How do you pronounce Leiningen?
A: It's LINE-ing-en. I think.
Q: What does this offer over Lancet?
A: Lancet is more of a library than a build tool. It doesn't predefine
any tasks apart from what Ant itself offers, so there is nothing
Clojure-specific there. In addition, Leiningen includes some Maven
functionality for dependencies.
Q: But Maven is terrifying!
A: That's not a question. Anyway, Leiningen only uses the dependency
resolution parts of Maven, which are quite tame. For the actual
task execution cycles it uses Ant under the covers via Lancet.
Q: But Ant is terrifying!
A: That's true. Ant is
an interpreter for a procedural language with a regrettable
syntax.
But if you're able to write it with a more pleasing syntax, it's
not so bad.
Q: What happened to Corkscrew?
A: I tried, but I really couldn't make the wine metaphor work. That,
and the Plexus Classworlds container was an ornery beast causing
much frustration.
Q: What about Windows?
A: Patches welcome.
