python - 是否可以将 bpython 用作完整的调试器？

Question

我想使用 bpython用于调试的解释器。我的问题类似于“Is it possible to go into ipython from code?”，它询问 ipython。

如果你使用 ipdb.set_trace() 你会得到一个完整的 ipython session 及其所有便利。然而，bpdb.set_trace() 并没有给我一个 bpython session ，它给了我标准的 pdb 调试器。

有什么方法可以设置以便我可以在 bpython session 中进行调试？

Answer 1

是的， 使用 this wrapper ，您也可以通过将语句 import bpdb 添加到代码中来访问它。将 bpdb.set_trace() 添加到您想要中断的任何位置，然后从 pdb 解释器输入“B”以跳转到包含所有内容的 bpython session 从堆栈帧:

    ### cmd.Cmd commands


    def do_Bpython(self, arg):
        bpython.embed(self.curframe.f_locals, ['-i'])


    def help_Bpython(self):
        print "B(python)"
        print
        print ("Invoke the bpython interpreter for this stack frame. To exit "
               "bpython and return to a standard pdb press Ctrl-d")


    ### shortcuts
    do_B = do_Bpython
    help_B = help_Bpython

你的问题对我来说似乎完全正确!
