如何增加吞吐任务的堆栈跟踪？ [英] how do I increase stack trace of gulp task?

我很难分辨出我的吞咽任务失败的原因以及原因。如何增加默认堆栈跟踪？

解决方案

添加评论和管道工：

1. 添加这个帮手方法：
   
   

   log =（msg） - >
   console.log msg
   ＃你会收到乙烯基文件为块
   transform =（file，cb） - >
   ＃读取和修改文件内容
   ＃file.contents = new Buffer（String （file.contents）+'一些修改过的内容'）;
   
   

    ＃如果出现错误，只需作为第一个参数传递这里
    cb（null，file）; 
     

   ＃返回地图将导致您的变换函数被称为
   ＃您收到的块（文件）。当这个流
   ＃收到一个'结束'信号时，它也会结束。
   ＃
   ＃此外，您还想在其他地方要求 event-stream 。
   return eventStream.map（transform）;




2. 任务中的步骤之间的管道日志方法：
   
   

   gulp.task'myTask'， - >
   gulp.src myCss，
   base：myBase
   .pipe log获得了css文件！
   .pipe concat'app.css'
   .pipe logconcated css !!

这是用coffeescript编写的，你可以在这里把它变成javascript：
http://js2coffee.org/

3. 创建catch错误帮助器方法：
   
   

   catchError =（err） - >
   plugins.util.beep（）＃ REF ;
   console.log err




4. 将plumber添加到插件：
   
   

   gulp.task' myTask'， - >
   gulp.src myCss，
   base：myBase
   .pipe plugins.plumber
   errorHandler：catchError
   .pipe log获得了css文件！
   .pipe concat'app.css'
   .pipe logconcated css !!

完成！ ：）

It's hard for me to tell where my gulp task is failing and why. How can I increase the default stack trace?

解决方案

Add comments and plumber:

1. Add this helper method:

   log = (msg) -> console.log msg # you're going to receive Vinyl files as chunks transform = (file, cb) -> # read and modify file contents # file.contents = new Buffer(String(file.contents) + ' some modified content');

   # if there was some error, just pass as the first parameter here
   cb(null, file);
   

   # returning the map will cause your transform function to be called # for each one of the chunks (files) you receive. And when this stream # receives a 'end' signal, it will end as well. # # Additionally, you want to require the event-stream somewhere else. return eventStream.map(transform);

2. pipe thw log method between steps in a task:

   gulp.task 'myTask', -> gulp.src myCss, base: myBase .pipe log "Got css files!" .pipe concat 'app.css' .pipe log "concated css!!"

this is written in coffeescript, you can turn it to javascript here: http://js2coffee.org/

3. create a catch error helper method:

   catchError = (err) -> plugins.util.beep() # ref; console.log err

4. add plumber to plugins:

   gulp.task 'myTask', -> gulp.src myCss, base: myBase .pipe plugins.plumber errorHandler: catchError .pipe log "Got css files!" .pipe concat 'app.css' .pipe log "concated css!!"

Done! :)
