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.
