 Take GoLand as an example, developers can debug the code: 
 
-1. Debug the whole program. Make sure all directories mentioned in [Makefile](../../Makefile) build_prepare sections are created in your eKuiper root path. Add your breakpoints. Open `cmd/kuiperd/main.go`. In the main function, you'll find a green triangle in the ruler, click it and select debug. Then create your stream/rule that would run through your breakpoint, the debugger will pause there.

Then create your stream/rule that would run through your breakpoint, the debugger will pause there.
 2. To debug a small portion of code, we recommend writing a unit test and debug it. You can go to any test file and find the same green triangle to run in debug mode. For example, `pkg/cast/cast_test.go` TestMapConvert_Funcs can run as debug.

 以 GoLand 为例，开发者可以对代码进行调试。
 
-1. 调试整个程序。确保 [Makefile](../../Makefile) build_prepare 部分提到的所有目录都在你的eKuiper根路径中创建。添加你的断点。打开 `cmd/kuiperd/main.go` 。在主函数中，你会发现标尺上有一个绿色的三角形，点击它并选择调试。然后创建你的流/规则，让它运行到你的断点，调试器会在那里暂停。

 2. 要调试一小部分代码，我们建议写一个单元测试并调试它。你可以到任何一个测试文件中，找到同样的绿色三角形，在调试模式下运行。例如，`pkg/cast/cast_test.go` TestMapConvert_Funcs 可以作为调试运行。
