Using libraries without Lein

[Kashyap CK]

Hi,

I am trying to use clj-http in my clojure program. I am trying to do the whole thing in a "light-weight" manner - without creating a project and all or using lein. Is that possible? or do I need to use Lein?

Regards,

Kashyap 

[Alex Miller]

Sure. You need a jar for Clojure and a jar for clj-http and then just run Java with those in a classpath:

java -cp clojure.jar:clj-http.jar my-program

There is a lighter weight tool that we've added in Clojure 1.9 (also works with 1.8) that can help in assembling classpaths and serving as a runner. All it's really doing is taking a statement of deps and building the classpath to make that call. If you're interested in that, this will be useful:

Thanks Alex ... just what I was looking for - putting the jars in classpath that is!

I'll try out the new tool a little later though.

Regards,

Kashyap

In addition to tools.deps, which reads dependencies etc from a deps.edn file, you might want to look at Boot http://boot-clj.com which allows you to use libraries via the command line without needing a project or source files etc:

 

    boot -d clj-http repl

 

This will start a Clojure REPL (anywhere) with the clj-http library loaded. Boot also has a call task that accepts Clojure code via the command-line:

 

    boot -d clj-http call -p -e “(require ‘[clj-http.client :as http])” -e ‘(http/get “http://google.com”)’

 

The -p option tells call to print the result of each expression.
