Leiningen project files are just Clojure data :)

<code>(-&gt; "/path/to/project.clj" slurp read-string (nth 2))</code>

blocks|key|327703|text|虽然您可以自己解析project.clj，但这可能很烦人。这也是大量的工作。相反，您可以直接执行以下操作：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|327704|(System/getProperty+"projectname.version")|code-block|syntax|javascript|327705|entityMap^0|9|B|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

While you can parse <code>project.clj</code> yourself, this may be annoying. It's also a lot of work. Instead, you can just do:

I use environ (<a href="https://github.com/weavejester/environ" rel="noreferrer">https://github.com/weavejester/environ</a>) which sucks in settings from a number of sources, including system properties. The project version appears as <code>:&lt;project-name&gt;-version</code>:

<pre><code>foobar.repl=&gt; (require '[environ.core :refer [env]])
nil
foobar.repl=&gt; (:foobar-version env)
"0.1.0-SNAPSHOT"
</code></pre>

blocks|key|327627|text|将以下代码添加到project.clj的末尾：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|327628|(def+project+(assoc-in+project+[:repl-options+:init]

Add the below code to the end of project.clj:

<pre><code>(def project (assoc-in project [:repl-options :init]
 `(~'def ~'project-version ~(project :version))))
</code></pre>

Now you will have a var called <code>project-version</code> in the initial namespace for the repl.

As <a href="https://stackoverflow.com/questions/16270805/how-to-get-the-version-of-the-current-clojure-project-in-the-repl/16272358#16272358">vemv</a> said, Leiningen project files are just Clojure data. So, it's easy to access your project as an ordinary <code>hash-map</code>:

<pre><code>(-&gt;&gt; "project.clj"
 slurp
 read-string
 (drop 2)
 (cons :version)
 (apply hash-map)
 (def project))
</code></pre>

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

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

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

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

<pre><code>(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)))})
</code></pre>

But, if you need only the version of your project and nothing more, then it's best to use <a href="https://stackoverflow.com/questions/16270805/how-to-get-the-version-of-the-current-clojure-project-in-the-repl/16274279#16274279">Ankur's</a> solution.

blocks|key|110417|text|要获得功能更全的方法，您可能希望查看Leiningen的configleaf插件(https://github.com/davidsantiago/configleaf)。它将使合并了活动配置文件的项目映射对您选择的命名空间中的项目代码可用。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|110418|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/davidsantiago/configleaf^0|15|17|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

For a more fully-featured approach, you might want to take a look at the configleaf plugin for Leiningen (<a href="https://github.com/davidsantiago/configleaf" rel="noreferrer">https://github.com/davidsantiago/configleaf</a>). It will make the project map, with active profiles merged in, available to project code in a namespace of your choosing.

blocks|key|110519|text|如果您需要在clojurescript中执行此操作，您可以(从另一个clj文件)创建一个宏，并从cljs代码中调用它：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|110520|;;ex:+macro.clj
(defmacro+get-project-version+[]+
++(System/getProperty+"penelope.version"))

In case you need to do this from clojurescript you could create a macro (from another clj file) and call it from the cljs code :
<pre><code>;;ex: macro.clj
(defmacro get-project-version [] 
 (System/getProperty &quot;penelope.version&quot;))

;;my_logic_code.cljs
(ns my-logic-code
 (:require-macros [macros :as m]))

(def project-version (m/get-project-version))
</code></pre>

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

For example, if there was a project defined:

<pre><code>(defproject blahproject "0.1.2" ....)
</code></pre>

When running a repl in the project directory, is there a function like this?

<pre><code>&gt; (project-version) 
;=&gt; 0.1.2 
</code></pre>

Getting the version of the current clojure project in the repl

可以在clojure repl中获取项目信息吗？例如，如果定义了一个项目：(defproject blahproject "0.1.2" ....)在项目目录中运行repl时，有这样的函数吗？> (project-version) ;=> 0.1.2
