lein环服务器与nrepl不尊敬cider-nrepl [英] lein ring server with nrepl doesn't honour cider-nrepl

问题描述

当我用 lein ring server 启动我当前的项目并尝试通过cider从Emacs连接到它时，我收到以下警告：

 ; CIDER 0.8.2（Java 1.7.0_51，Clojure 1.6.0，nREPL 0.2.6）
警告：不支持以下必需的nREPL操作：
 apropos classpath complete eldoc info inspect-start inspect-refresh check-pop inspect-push inspect-reset macroexpand ns-list ns-vars resource stacktrace toggle-trace-var toggle-trace-ns undef 
请安装（或更新）cider-nrepl 0.8.2并重新启动CIDER 
 user>但是，我有一个依赖关系 [cider / cider-nrepl] 0.8.2] 在我的 project.clj 。这是工作很好，当我运行 lein repl ，然后我可以连接刚从cider：
 ; CIDER 0.8.2（Java 1.7.0_51，Clojure 1.6.0，nREPL 0.2.6）
 swedishchef.handler> 
  
我可以看到我从leiningen wrt收到两条不同的消息。 nREPL，取决于我如何开始：
  [sugarcube-> swedishchef] lein环服务器
请参阅https： /github.com/technomancy/leiningen/wiki/Repeatability）
在端口44231上启动nREPL服务器
  
这是与工作cider-nrepl连接的输出：
  [sugarcube-> swedishchef] lein repl 
查看https://github.com/technomancy/leiningen/wiki/Repeatability）
 nREPL服务器在主机127.0.0.1上的端口38024上启动 -  nrepl：//127.0.0.1：38024 
 REPL-y 0.3.5，nREPL 0.2.6 
  
查看 lein deps的输出：tree 我没有看到任何问题。所以，我的第一个问题是，这是否应该工作，即如果 cider-nrepl 应该覆盖 lein ring  wrt。到nrepl启动？ 
解决方案
使用最新 lein-ring 插件版本0.9.2，并将：repl-options 添加：nrepl-middleware  $ c> in your project.clj 
 
 
 
例如，我通过 lein new compojure-app my-app 。然后，我通过在〜/ .lein / profiles.clj  ex中创建一个空的leiningen配置文件来测试它。  {：yolo {}} ，并通过 lein with-profile yolo，dev环服务器启动环服务器。

When I start up my current project with lein ring server and try to connect to it from Emacs via cider, I get the following warning: 
; CIDER 0.8.2 (Java 1.7.0_51, Clojure 1.6.0, nREPL 0.2.6)
WARNING: The following required nREPL ops are not supported:

Please, install (or update) cider-nrepl 0.8.2 and restart CIDER

However, I do have a dependency for [cider/cider-nrepl "0.8.2"] in my project.clj. This is working just fine when I run lein repl and to which I can then connect just fine from cider:
; CIDER 0.8.2 (Java 1.7.0_51, Clojure 1.6.0, nREPL 0.2.6)
swedishchef.handler>
I can see that I get two different messages from leiningen wrt. nREPL, depending on how I start:
[sugarcube->swedishchef]lein ring server
See https://github.com/technomancy/leiningen/wiki/Repeatability)
Started nREPL server on port 44231
This is the output with the working cider-nrepl connection:
[sugarcube->swedishchef]lein repl
See https://github.com/technomancy/leiningen/wiki/Repeatability)
nREPL server started on port 38024 on host 127.0.0.1 - nrepl://127.0.0.1:38024
REPL-y 0.3.5, nREPL 0.2.6
Looking at the output of lein deps :tree I don't see any problems. So, my first question is whether this supposed to work, i.e., if cider-nrepl should override lein rings behavior wrt. to nrepl startup? If so, could somebody give some advice for further troubleshooting?
解决方案
Use latest lein-ring plugin version 0.9.2 and add :nrepl-middleware containing vector of nrepl-middlewares to :repl-options in your project.clj

For example, I create the project by lein new compojure-app my-app. Then, I tested it by creating a empty leiningen profile in ~/.lein/profiles.clj ex. {:yolo {}} and starting ring server by lein with-profile yolo,dev ring server.
