Getting the version of the current clojure project in the repl

Question

Is it possible to grab the project information within the clojure repl?

For example, if there was a project defined:

(defproject blahproject \"0.1.2\

As vemv said, Leiningen project files are just Clojure data. So, it's easy to access your project as an ordinary hash-map:

(->> "project.clj"
     slurp
     read-string
     (drop 2)
     (cons :version)
     (apply hash-map)
     (def project))

If you need this variable only in your repl, you can add it to repl-options to your project.clj:

(defproject yourproject "0.1.0"
  :description ""
  :url ""
  :dependencies [ [org.clojure/clojure  "1.4.0"]]
  :repl-options { :init (->>  "project.clj"
                              slurp
                              read-string
                              (drop 2)
                              (cons :version)
                              (apply hash-map)
                              (def project))})

Now, you have project variable in your repl. So, to access the version of your project you can simply type (:version project).

Of course, you can simply use native Leiningen code to parse you project file:

(defproject yourproject "0.1.0"
  :description ""
  :url ""
  :dependencies [ [org.clojure/clojure  "1.4.0"]
                  [leiningen-core       "2.1.3"]]
  :repl-options { :init (do (require 'leiningen.core.project)
                            (def project
                                 (leiningen.core.project/read)))})

But, if you need only the version of your project and nothing more, then it's best to use Ankur's solution.
