我正在使用lein2。我想在repl启动时默认加载一些ns。当为该项目执行lein2 repl时,是否可以在project.clj中指定应该加载的ns?
您将在示例项目中找到很多答案
;; Options to change the way the REPL behaves
:repl-options {;; Specify the string to print when prompting for input.
;; defaults to something like (fn [ns] (str *ns* "=> "))
:prompt (fn [ns] (str "your command for <" ns ">, master? " ))
;; Specify the ns to start the REPL in (overrides :main in
;; this case only)
:init-ns foo.bar
;; This expression will run when first opening a REPL, in the
;; namespace from :init-ns or :main if specified
;; This expression will run when first opening a REPL, in the
;; namespace from :init-ns or :main if specified
:init (println "here we are in" *ns*)
使用project.clj
我有一个方便的:
(defproject test "1.0.0"
:repl-options { :init-ns test.core
:init (do
(use 'clojure.set)
(println (union #{1 2 3} #{3 4 5}))
(use 'incanter.core)
(println (factorial 5))) }
:dependencies [[org.clojure/clojure "1.4.0"]
[incanter/incanter-core "1.3.0-SNAPSHOT"]])
当我启动lein repl
时
$ lein repl
nREPL server started on port 1121
REPL-y 0.1.0-beta10
Clojure 1.4.0

test.core=>
我有时在project.clj
中使用:injections
选项以加载命名空间。以下示例将加载执行lein2
命令时的foo.bar
命名空间:
(defproject org.example/sample "0.1.0-SNAPSHOT"
:description "A sample project"
:url "http://example.com/FIXME"
:license {:name "Eclipse Public License"
:url "http://www.eclipse.org/legal/epl-v10.html"}
:injections [(use 'foo.bar)])
