使用byebug gem让我能够continue直到下一个断点:

(byebug) help

  break      -- Sets breakpoints in the source code
  catch      -- Handles exception catchpoints
  condition  -- Sets conditions on breakpoints
  continue   -- Runs until program ends, hits a breakpoint or reaches a line
  delete     -- Deletes breakpoints
  disable    -- Disables breakpoints or displays
  display    -- Evaluates expressions every time the debugger stops
  down       -- Moves to a lower frame in the stack trace
  edit       -- Edits source files
  enable     -- Enables breakpoints or displays
  finish     -- Runs the program until frame returns
  frame      -- Moves to a frame in the call stack
  help       -- Helps you using byebug
  history    -- Shows byebug's history of commands
  info       -- Shows several informations about the program being debugged
  interrupt  -- Interrupts the program
  irb        -- Starts an IRB session
  kill       -- Sends a signal to the current process
  list       -- Lists lines of source code
  method     -- Shows methods of an object, class or module
  next       -- Runs one or more lines of code
  pry        -- Starts a Pry session
  ps         -- Evaluates an expression and prettyprints & sort the result
  quit       -- Exits byebug
  restart    -- Restarts the debugged program
  save       -- Saves current byebug session to a file
  set        -- Modifies byebug settings
  show       -- Shows byebug settings
  source     -- Restores a previously saved byebug session
  step       -- Steps into blocks or methods one or more times
  thread     -- Commands to manipulate threads
  tracevar   -- Enables tracing of a global variable
  undisplay  -- Stops displaying all or some expressions when program stops
  untracevar -- Stops tracing a global variable
  up         -- Moves to a higher frame in the stack trace
  var        -- Shows variables and its values
  where      -- Displays the backtrace

我全神贯注地看到了#34;继续没有断点"。我能想到的唯一方法是删除或评论byebug语句,退出q!并重新开始测试。

如何在不停止Ruby中的其他byebug语句的情况下继续?

代码中的byebug方法调用不是“断点”(考虑帮助输出中对断点的引用)。

根据帮助输出,可以使用breakpoint命令禁用disable。但这并不能解决您的问题,因为下一个byebug将暂停执行。

由于byebug只是一个方法调用,因此可以使其成为条件:

byebug if SomeModule.byebug?

然后,在SomeModule中,您可以使用全局变量来打开/关闭它。您要么在调用byebug的所有调用时执行此操作,要么可以使用byebug方法对其执行相同操作,alias_method_chain或类似的操作。

Make Byebug finish executing without exiting Pry”是一个类似的答案。

我刚刚在code中发现,您可以使用以下命令完全停止调试:

Byebug.mode = :off

您无法重新打开它,因为它不再附着在其上,但这很方便,例如在调试要完成运行的脚本时。

您可以使用continue!
