AOT compilation newbie mistakes

[Isaac Gouy]

$ /usr/local/src/jdk1.6.0_18/bin/java -cp .:clojure.jar clojure.main
Clojure 1.2.0
user=> (compile 'clojure.examples.hello)
java.io.IOException: No such file or directory (hello.clj:1)


$ ls clojure/examples
hello.clj


$ cat clojure/examples/hello.clj
(ns clojure.examples.hello
(:gen-class))

(defn -main
[greetee]
(println (str "Hello " greetee "!")))


1) What do I need to do to have the REPL find hello.clj ?

2) How can I AOT compile Clojure files without using the REPL?

[Robert McIntyre]

I feel like a lot of people have trouble with this (I certainly do!)
so I made this tutorial with working examples to follow.

it's at:

http://www.rlmcintyre.com/iassac-gouy.tar.bz2
or
http://www.bortreb.com/iassac-gouy.tar.bz2

just unpack it into your home directory , read the
README, and play around.

It shows how to compile stuff from the command line and the REPL
and how to make shell-scripts.

happy coding,

on this point, I think most people use build tools to do it.

gradle with clojuresque plugin, lein and mvn with clojure plugin will
all do this.

Thanks

$ /usr/local/src/jdk1.6.0_18/bin/java -cp .:clojure.jar -
Dclojure.compile.path=. clojure.main

Clojure 1.2.0
user=> (compile 'clojure.examples.hello)

clojure.examples.hello

$ /usr/local/src/jdk1.6.0_18/bin/java -cp clojure.jar
clojure.examples.hello Fred
Hello Fred!


Is there are reason not to simplify further?

$ cat hello.clj
(ns hello

(:gen-class))

(defn -main
[greetee]
(println (str "Hello " greetee "!")))

$ /usr/local/src/jdk1.6.0_18/bin/java -cp .:clojure.jar -
Dclojure.compile.path=. clojure.main
Clojure 1.2.0
user=> (compile 'hello)
hello


$ /usr/local/src/jdk1.6.0_18/bin/java -cp clojure.jar hello John
Hello John!

oh yes -- please don't do it manually for anything "production"

But, it's good to know what's actually going on behind the scenes,
especially when things stop working :)

For my simple needs -

java -cp .:clojure.jar -Dclojure.compile.path=.
clojure.lang.Compile hello

- is exactly what I was looking for.
