将compojure服务器打印语句输出到figwheel终端？ [英] Output compojure server print statements into figwheel terminal?

问题描述

pprint / println 输出在哪里组合？/我可以在终端中显示它吗？在运行Figwheel repl的窗口？ （抱歉，这听起来很愚蠢，谷歌竭尽全力。）

Where does pprint/println output go in compojure?/Can I get it to show up in the terminal window that the figwheel repl is running in? (Sorry if this sounds dumb, google bested my efforts).

推荐答案

实际上Figwheel具有引起此类症状的相关功能。环形处理程序中的所有print / prn语句将被Figwheel进程吞噬，并进入日志文件或控制台。

Actually Figwheel has a related feature to cause such symptoms. All print/prn statements in your ring handlers will be "swallowed" by the Figwheel process and will either go to a log file or to the console.

这是project.clj的摘录：

Here is a snippet from project.clj:

 :figwheel
  {:http-server-root "public"
   :server-port 3449
   :nrepl-port 7002
   :css-dirs ["resources/public/css"]
   :ring-handler myapp.handler/app
   :server-logfile false
   }

密钥：server-logfile正在控制此行为。如果为假，则 out 是常规的repl控制台，如果它是文件名，则打印的所有内容都将进入该文件（如果不存在，则默认使用文件 figwheel_server.log。

The key :server-logfile is controlling this behavior. If it's false, then out is your regular repl console, if it's a filename, then anything printed will go to that file (if it's not present, then the default is using file "figwheel_server.log".
