英文:
How can I set breakpoints by the sourcefile line number in Delve?
问题
标题基本上已经说明了一切。
我所知道的设置断点的唯一方法是在程序运行时或者在 breakpoint main.main 之前设置。
我能否通过行号来设置断点，例如 breakpoint ./otherfile.go:200？
英文:
The title pretty much says it all.
The only way I know how to set one is either during the runtime of the program or just before with breakpoint main.main
Is there a way I can do this by line number like breakpoint ./otherfile.go:200?

在你的源代码中输入
runtime.Breakpoint()
在命令行界面中输入
dlv test
然后输入
continue
程序将在设置断点的代码行停止。
英文:
In your Source code type
runtime.Breakpoint()
type in the CLI
> dlv test
and then
> continue
The program will stop in the line of code where you set the breakpoint.

以下是在 delve 中有效的内容：
(dlv) break <断点名称> <文件名模式>:<行号>
如果你的文件名存在歧义，比如 main.go 分散在你的源代码和可能的供应商目录中，只需确保它在 delve 中看起来“唯一”（filename_pattern 不是你的确切文件位置）。例如：
(dlv) break myLoopingStuff project_name/loops.go:30
(dlv) condition myLoopingStuff thing == someOther.thing
英文:
The following is valid in delve:
(dlv) break <breakpoint_name> <filename_pattern>:<line_number>
If you have ambiguous filenames, say main.go spread all over your sources and possibly vendor directory, just make you make it look "unique" to delve (filename_pattern is not your exact file location). For example:
(dlv) break myLoopingStuff project_name/loops.go:30
(dlv) condition myLoopingStuff thing == someOther.thing
