我可以在REPL的Lein项目中查找内容吗？

Question

说我有一个香草project.clj像

(defproject myservice "0.1.0-SNAPSHOT" 
    :description "FIXME: write description" 
    :url "http://example.com/FIXME" 
    :mailing-list {:name "myservice@example.com" :post "myservice@climate.com"} 
    :license {:name "Eclipse Public License" 
      :url "http://www.eclipse.org/legal/epl-v10.html"} 

    :dependencies [[org.clojure/clojure "1.6.0"] 
       [ring/ring-core "1.4.0"] 
       [ring/ring-jetty-adapter "1.4.0"] 
       [compojure "1.4.0"] 
       [ring/ring-defaults "0.1.5"] 
       [org.clojure/tools.logging "0.3.1"] 
       [clj-http "2.0.0"]] 

    :plugins [[lein-ring "0.9.7"]] 

    :ring {:handler myservice.core/standalone-app 
     :port 3000} 
    :profiles { 
      :uberjar {:ring {:handler myservice.core/app}}} 
) 

在lein repl，我可以从project.clj查找值？怎么样？当然，我的盲人黑客没有工作？

user=> (:mailing-list project) 
CompilerException java.lang.RuntimeException: Unable to resolve symbol: project in this context, compiling:(/private/var/folders/1g/fnytl2x93sx6hp2f1rsf4h1r5xtqv_/T/form-init6671981825845237047.clj:1:1) 

下面的问题是我可以使用project.clj中的项目映射吗？就像我想拉取邮件列表一样：命名并替换为：deb：maintainer？

:deb 
    {:toDir "target" 
    :package "mysevice" 
    :maintainer {:name "Meeples", :email "myservice@example.com"} 
    ... 
    } 

我敢肯定，你可以告诉我是那种-的新本，但project.clj仅仅是可执行的Clojure，不是吗？如果我知道项目地图的名称，我应该可以查询它，对吧？

可以def数据，你通常会和它们包括使用~

(def mailing-list {:name "myservice@example.com" :post "myservice@climate.com"}) 

(defproject myservice "0.1.0-SNAPSHOT" 
    :description "FIXME: write description" 
    :url "http://example.com/FIXME" 
    :mailing-list ~mailing-list 
    :license {:name "Eclipse Public License" 
      :url "http://www.eclipse.org/legal/epl-v10.html"} 

    :dependencies [[org.clojure/clojure "1.6.0"] 
       [ring/ring-core "1.4.0"] 
       [ring/ring-jetty-adapter "1.4.0"] 
       [compojure "1.4.0"] 
       [ring/ring-defaults "0.1.5"] 
       [org.clojure/tools.logging "0.3.1"] 
       [clj-http "2.0.0"]] 

    :plugins [[lein-ring "0.9.7"]] 

    :ring {:handler myservice.core/standalone-app 
     :port 3000} 
    :profiles { 
      :uberjar {:ring {:handler myservice.core/app}}} 
    :deb { 
     :toDir "target" 
     :package "mysevice" 
     :maintainer {:name "Meeples", :email (:name ~mailing-list)}})

这是leiningen相关线路：https://github.com/technomancy/leiningen/blob/b29b2ea41b6d177a8a57493b979164eab0931e4d/leiningen-core/src/leiningen/core/project.clj#L405

鉴于命名空间leiningen.core.project，地图应该是在它之下。
