Re: Getting started with open source Clojure projects
Thanks for all the quick replies. I should've mentioned that I'm already using leiningen, so the problem isn't so much getting the dependencies and building the application as it is figuring out a way to get inside the code and play with it a bit. I'd like to be able to load the source files, execute member functions, and just get a feel for what's going on internally. What sort of method do you all use for exploring open source projects? Do you just read the source code, or do you load it and test it out?

Well, I have a ~/lib/clojure directory and a clj script that
automatically puts that directory and all .jar's in it on the
classpath. Linux version:
#!/bin/bash
: ${CLOJURE_LIB:=${HOME}/lib/clojure}
export
CLASSPATH=${CLASSPATH:+$CLASSPATH:}$HOME/lib/java/clojure.jar:$CLOJURE_LIB
if [ -d $CLOJURE_LIB ]; then
for f in $CLOJURE_LIB/*.jar; do
if [ -r $f ]; then
CLASSPATH=$CLASSPATH:$f
fi
done
fi
rlwrap java clojure.main $@
The actual java invocation can of course be replaced to e.g. use JLine
instead of rlwrap; I use the latter because JLine doesn't seem to have
a vi mode. (Yes, I know, vi user in a Lispy language - heretical!)

Daniel cotter.dan...@gmail.com writes: Am I going about this the wrong way? Is there an easier way to explore existing open-source projects? I Try this for any leiningen project (check for the existence of a project.clj file). I'm assuming you're using a unixy operating system. First and once-off, install leiningen: wget http://github.com/technomancy/leiningen/raw/stable/bin/lein chmod a+x lein ./lein self-install Clone target project (in this case Compojure): git clone git://github.com/weavejester/compojure.git cd compojure Ask Lein to download Compojure's dependencies (this includes Clojure, you don't need to it install it manually): ../lein deps Fire up a repl: ../lein repl Clojure 1.1.0 user= (use 'compojure.core) nil Alternatively if you're using Java 6 you can start the REPL without any wrapper script pretty easily. I prefer to do it this way as it makes it obvious what the classpath is and allows tweaking the JVM options (for example increasing the memory limit with -Xmx256m). java -cp 'lib/*:classes:src' clojure.main Clojure 1.1.0 user= (use 'compojure.core) nil Is there a less cumbersome way to get a load of files on the classpath than manually editing the .clojure file? Note the wildcard 'lib/*' notation I used above. This was added in Java 6. Be aware that it has to be some/directory/* not *.jar, foo* or any other variation. Put it in single quotes to make sure your shell doesn't try and expand it. It'll add any jar files found in the directory to the classpath. Hope that helps.

RE: Getting started with open source Clojure projects
So here are my questions: Am I going about this the wrong way? Is there an easier way to explore existing open-source projects? I Is there a less cumbersome way to get a load of files on the classpath than manually editing the .clojure file? How do I tell the REPL where to find response.clj so that core.clj will load? For Compojure I think you need also Ring: http://github.com/mmcgrana/ring (also a mailing list here: http://groups.google.com/group/ring-clojure) There's been a lot of activity there recently, various projects refactoring in terms of each other, and that seems to be where they're ending up. I don't know too much about it, but I did run through the code and examples just yesterday. The other thing is: leiningen. http://github.com/technomancy/leiningen A lot of projects are using it, and it's dead simple dependency management. Download the project, look for the project.clj file, run 'lein deps' in that directory, and you get all needed dependency jars loaded into a 'lib' subdirectory. cheers, Kevin Kelley -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Getting started with open source Clojure projects
Take a look at the dependency management tools. Most open-source Clojure projects use either Maven and Leiningen. Both use the same dependency model and provide similar capabilities for starting a REPL with the classpath configured automatically. -SS On Mar 29, 11:39 pm, Daniel cotter.dan...@gmail.com wrote: If this is a dumb question, let me apologize in advance. The thing is, I've been trying to learn Clojure in my spare time, and, following the advice of several Clojure blogs, started by reading Halloway's book and playing around a bit at the REPL, which is all well and good, but now I'm ready to tackle something a little bigger. The project that interests me most is James Reeve's Compojure, so I cloned the repository with the intention of loading the source files into the REPL and testing out some of the functions to get an idea of how it works internally. The first hurdle was getting all the dependent classes on the classpath, which I did by adding them one by one to the .clojure file (I'm using a script that concatenates the contents of .clojure to the classpath before launching the REPL). So far, so good. However, when I try to load core.clj from the REPL, it complains about not being able to find compojure/response.clj or its equivalent class. And it does this even if I load response.clj first, then try to load core.clj. So here are my questions: Am I going about this the wrong way? Is there an easier way to explore existing open-source projects? I Is there a less cumbersome way to get a load of files on the classpath than manually editing the .clojure file?

There are also gradle and ant combined with Ivy as possible helpers. They also build on the maven repositories. So they should work fine, too.

Re: Getting started with open source Clojure projects
If you're not stuck on using Compojure, you can try Conjure which will includes all of the dependencies in the jar. To start a hello world app: 1. Download conjure.jar from: http://github.com/macourtney/Conjure/downloads 2. java -jar conjure.jar hello_world 3. cd hello_world 4. ./run.sh script/server.clj 5.
