是否可以将 bpython 用作完整的调试器？

Question

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

如果您使用ipdb.set_trace()，您将获得完整的ipython 会话及其所有便利。然而，bpdb.set_trace() 没有给我一个 bpython 会话，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 会话中进行调试？

Answer 1

是的，使用this wrapper，您也可以通过将语句import bpdb 添加到您的代码来访问它。在您想中断的地方添加bpdb.set_trace()，然后在pdb 解释器中输入“B”以跳转到bpython 会话，其中包含堆栈框架中的所有内容：

import pdb
import bpython

class BPdb(pdb.Pdb):
    """ PDB with BPython support. """

    def __init__(self):
        pdb.Pdb.__init__(self)
        self.rcLines = []
        self.prompt = '(BPdb) '
        self.intro = 'Use "B" to enter bpython, Ctrl-d to exit it.'

    def postloop(self):
        # We only want to show the intro message once.
        self.intro = None
        pdb.Pdb.postloop(self)

    ### 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！

Answer 2

如果您正在寻找一个看起来更酷的调试器，它可以完成补全和语法突出显示，您可能想看看 pdb++。 http://pypi.python.org/pypi/pdbpp/

它是 pdb 的替代品。所以你可以继续使用

 import pdb; pdb.set_trace()

它会让你进入 pdb++ 提示符。
