使用ipdb默认进入粘性模式

Question

使用

ipdb

进行调试时，我发现进入

sticky

模式以跟踪代码源很有用。有没有办法在粘滞模式下自动输入而无需输入

sticky

？

Answer 1

是的，从自述文件中：将名为

.pdbrc.py

的文件放入您的主目录中，其中包含：

import pdb
class Config(pdb.DefaultConfig):
    sticky_by_default = True

Answer 2

正如 @Patrick 的回答以及 @bartekbrak 对他的回答的评论中提到的，由于 Pdb++ (

pdbpp

) 是

pdb

的替代品，你可以与

ipdb

同时安装它，并且由于

idbp

调用

pdb

，您可以利用一些

pdb

功能，例如

sticky

。

这是来自

https://pypi.org/project/pdbpp/

的默认值 .pdbrc.py。 （我可能已经改变了）。它默认包含

sticky

以及许多您可能喜欢的其他内容。

请注意，Pdb++ 安装为

pdbpp

，但仍导入/显示为

pdb

:

# ~/.pdbrc.py
# https://pypi.org/project/pdbpp/
# pip install pdbpp
# import pdb; pdb.set_trace()

import pdb


class Config(pdb.DefaultConfig):

    # The prompt to show when in interactive mode.
    prompt = '(Pdb++) '

    # Highlight line numbers and the current line when showing the longlist of a function or when in sticky mode.
    highlight = True

    # File encoding.
    # Useful when there are international characters in your string literals or comments.
    encoding = 'utf-8'

    # Determine whether pdb++ starts in sticky mode or not.
    sticky_by_default = False

    # The color to use for line numbers.
    line_number_color = pdb.Color.turquoise

    # The color to use for file names when printing the stack entries.
    filename_color = pdb.Color.yellow

    # The SGR parameters for the ANSI escape sequence to highlight the current line.
    # This is set inside the SGR escape sequence \e[%sm where \e is the ESC character and %s the given value. See SGR parameters.
    # The following means "reset all colors" (0), set foreground color to 18 (48;5;18), and background to 21.
    # The default uses the default foreground (39) and background (49) colors, inversed (7).
    current_line_color = "39;49;7"

    # If pygments is installed and highlight == True, apply syntax highlight to the source code when showing the longlist of a function or when in sticky mode.
    use_pygments = True

    # Passed directly to the pygments.formatters.TerminalFormatter constructor.
    # Selects the color scheme to use, depending on the background color of your terminal.
    # If you have a light background color, try to set it to 'light'.
    bg = 'dark'

    # Passed directly to the pygments.formatters.TerminalFormatter constructor.
    # It expects a dictionary that maps token types to (lightbg, darkbg) color names or None (default: None = use builtin colorscheme).
    colorscheme = None

    # The command to invoke when using the edit command.
    # By default, it uses $EDITOR if set, else vi.
    # The command must support the standard notation COMMAND +n filename to open filename at line n.
    editor = '${EDITOR:-vi}'

    # Truncate lines which exceed the terminal width.
    truncate_long_lines = True

    # Shell command to execute when starting the pdb prompt and the terminal window is not focused.
    # Useful to e.g. play a sound to alert the user that the execution of the program stopped. It requires the wmctrl module.
    exec_if_unfocused = None

    # Old versions of pytest crash when you execute pdb.set_trace() in a test, but the standard output is captured (i.e., without the -s option, which is the default behavior).
    # When this option is on, the stdout capturing is automatically disabled before showing the interactive prompt.
    disable_pytest_capturing = False

    # Certain frames can be hidden by default.
    # If enabled, the commands hf_unhide, hf_hide, and hf_list can be used to control display of them.
    enable_hidden_frames = True

    # If enable_hidden_frames is True this controls if the number of hidden frames gets displayed.
    show_hidden_frames_count = True

    # This method is called during the initialization of the Pdb class.
    # Useful to do complex setup.
    def setup(self, pdb):
        pass

    # Display tracebacks for errors via Pdb.error, that come from Pdb.default (i.e. the execution of an unrecognized pdb command),
    # and are not a direct cause of the expression itself (e.g. NameError with a command like doesnotexist).
    # With this option disabled only *** exception string gets printed, which often misses useful context.
    show_traceback_on_error = True

    # This option sets the limit to be used with traceback.format_exception, when show_traceback_on_error is enabled.
    show_traceback_on_error_limit = None
