Clojure 是一个面向Java Virtual Machine 的动态语言。

Lisp 是一种编程语言，以表达性和功能强大著称，但人们通常认为它不太适合应用于一般情况。Clojure 是一种运行在 Java平台上的 Lisp 方言，它的出现彻底改变了这一现状。如今，在任何具备 Java 虚拟机的地方，您都可以利用 Lisp 的强大功能。

Mac OS X

使用leiningen工具来管理Clojure项目和Java配置。

获得 https://raw.github.com/technomancy/leiningen/preview/bin/lein 并放到 /bin 目录下，chmod 755

cd bin，执行 ./lein // 开始安装 Leiningen

Leiningen is a tool for working with Clojure projects.

Several tasks are available:

check               Check syntax and warn on reflection.
classpath           Write the classpath of the current project to output-file.
clean               Remove all files from project's target-path.
compile             Compile Clojure source into .class files.
deploy              Build jar and deploy to remote repository.
deps                Show details about dependencies.
do                  Higher-order task to perform other tasks in succession.
help                Display a list of tasks or help for a given task.
install             Install current project to the local repository.
jar                 Package up all the project's files into a jar file.
javac               Compile Java source files. 
new                 Generate project scaffolding based on a template.
plugin              DEPRECATED. Please use the :user profile instead.
pom                 Write a pom.xml file to disk for Maven interoperability.
repl                Start a repl session either with the current project or standalone.
retest              Run only the test namespaces which failed last time around.
run                 Run the project's -main function.
search              Search remote maven repositories for matching jars.
show-profiles       List all available profiles or display one if given an argument.
test                Run the project's tests.
trampoline          Run a task without nesting the project's JVM inside Leiningen's.
uberjar             Package up the project files and all dependencies into a jar file.
upgrade             Upgrade Leiningen to specified version or latest stable.
version             Print version for Leiningen and the current JVM.
with-profile        Apply the given task with the profile(s) specified.

Run lein help $TASK for details.

接着：

lein new start-clojure
cd start-clojure
lein repl
将获得一些jar，如：
Retrieving org/clojure/clojure/1.4.0/clojure-1.4.0.jar ...
user=>  (println "Give me some Clojure!")
Give me some Clojure!
nil
