用于读取Erlang控制台或错误日志的工具

我是新来的二郎，芝加哥老板只用了几个星期就开始使用它们了，所以我一直在犯错误。这并没有让我太烦恼，因为这都是学习的一部分

但真正让我沮丧的是控制台和错误日志，我发现它们几乎不可能被读取，因为每一个内容都在一行中出现，我无法区分堆栈消息的一个级别和另一个级别。更令人恼火的是，字符串中有结构，但所有这些都被抹去了

不管怎样，是否可以以更容易理解的形式查看这些日志，比如php如何将错误打印到网页上，或者数组的print_r函数，可能在Chicago boss中有所体现

示例：

任何帮助都是适当的

如果他们能很好地打印错误消息，那就好了，但是你可以自己做，麻烦一点。消息的内容是一个erlang术语，在本例中是一个列表。只需将erlang术语复制并经过shell，添加一个句点，使其成为法律声明：

> [{simple_bridge_request_wrapper,post_param,[{simple_bridge_request_wrapper,mochiweb_request_bridge,{mochicow_request,#Port<0.41310>,'POST',"/greeting/list",'HTTP/1.1',{9,{"host",{"host","jason-virtualbox:8001"},{"accept",{"accept", "text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8"},nil,{"accept-language",{"accept-language","en-US,en;q=0.5"},{"accept-encoding",{"accept-encoding","gzip, deflate"},nil,nil},{"connection",{"connection","keep-alive"},nil,{"content-type",{"content-type","application/x-www-form-urlencoded"},{"content-length",{"content-length","44"},nil,nil},nil}}}},{"user-agent",{"user-agent","Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0"},{"referer",{"referer","http://****:8001/greeting/hello"},nil,nil},nil}}},<<"SheetName=%7BBook1.2%7D%2C%7B0-Sheet1.csv%7D">>},false,[],[],none}],[]},{pigeon_greeting_controller,list,3,[{file,"/home/jason/pigeon/src/controller/pigeon_greeting_controller.erl"},{line,34}]},{boss_web_controller,call_controller_action,3,[{file,"src/boss/boss_web_controller.erl"},{line,363}]},{boss_web_controller,apply_action,4,[{file,"src/boss/boss_web_controller.erl"},{line,355}]},{boss_web_controller,execute_action_inner,9,[{file,"src/boss/boss_web_controller.erl"},{line,334}]},{boss_web_controller_handle_request,process_dynamic_request,4,[{file,"src/boss/boss_web_controller_handle_request.erl"},{line,242}]},{boss_web_controller_handle_request,process_request,4,[{file,"src/boss/boss_web_controller_handle_request.erl"},{line,228}]},{boss_web_controller_handle_request,set_timer,7,[{file,"src/boss/boss_web_controller_handle_request.erl"},{line,148}]}].

哦，显然在erlang中没有端口的文字表示，所以他们打印了一个端口的简要描述：

#port

。在erlang中，您可以用单引号将非法字符包装起来，我认为这样可以创建一个atom，这是一个合法的术语，因此shell将允许它：

“#Port”

。那么：
