如何运行直到delve中的某行？

Question

假设我有这样的代码

   362:
=> 363:     for _, header := range MyHeaders {
   364:         b.applyHeader(header)
   365:     }
   366:
   367:     if b.headers != nil {
   368:         req.Header = b.headers
(dlv)

我想跳过第 363 行的循环并跳到第 367 行。

delve中有一个简单的命令吗，类似于gdb的until（这里提到过）

我可以通过在第 367 行添加断点，然后继续，然后删除断点来实现这一点。但我不想每次需要时都创建/删除断点。

Answer 1

next 3

将跳过一些行并停止下面的 3 行。

Answer 2

continue [<locspec>]

命令具有此功能。

locspec

记录在here。当前文件中的行号是有效的

locspec

。
