If you want display current line again, specify the line number.

I just noticed an odd behavior when using l (i.e. the list command) in ipdb. I think I have seen something similar with the Perl debugger in the past, but it still puzzles me., [FIXED] Visual studio code: "matplotlib" is not accessed Pylance Issue I get the error in the title when I try to import matplotlib. Please I have been sea... ,Many command line debuggers behave that way. (pdb, gdb, ipdb ...).,The first time I inoke it shows corerectly ~10 lines of code around the current step (breakpoint). However, if I press it repeatedly, it does not show code around the current location anymore, but instead it shows code that comes below it.

If you want display current line again, specify the line number.

If you go this route, one way to exit "debugging mode" and ignore all subsequent breakpoints, is to use ipshell.dummy_mode = True which will make Python ignore any subsequent instantiations of the ipshell object that we created above.,See the ipdb repo and a list of commands. IPython is now called (edit: part of) Jupyter.,This allows for full inspection of your code, and you have access to commands such as c (continue), n (execute next line), s (step into the method at point) and so on.,ps: note that an ipdb command takes precedence over python code. So in order to write list(foo) you'd need print(list(foo)), or !list(foo) .

Add the following on a script to your PYTHONPATH, so that the method ipsh() becomes available.

import inspect # First
import the embed
function from IPython.terminal.embed
import InteractiveShellEmbed from IPython.config.loader
import Config # Configure the prompt so that I know I am in a nested(embedded) shell cfg = Config() prompt_config = cfg.PromptManager prompt_config.in_template = 'N.In <\\#>: '
prompt_config.in2_template = '   .\\D.: '
prompt_config.out_template = 'N.Out<\\#>: '
# Messages displayed when I drop into and exit the shell.banner_msg = ("\n**Nested Interpreter:\n"
   "Hit Ctrl-D to exit interpreter and continue program.\n"
   "Note that if you use %kill_embedded, you can fully deactivate\n"
   "This embedded instance so it will never turn on again") exit_msg = '**Leaving Nested interpreter'
# Wrap it in a
function that gives me more context: def ipsh(): ipshell = InteractiveShellEmbed(config = cfg, banner1 = banner_msg, exit_msg = exit_msg) frame = inspect.currentframe().f_back msg = 'Stopped at {0.f_code.co_filename} at line {0.f_lineno}'.format(frame) # Go back one level!# This is needed because the call to ipshell is inside the
function ipsh() ipshell(msg, stack_depth = 2)

Using it:

def my_function(b): a = b ipsh() # < -This will embed a full - fledged IPython interpreter a = 4

The new approach seems to be:

from IPython.core
import debugger debug = debugger.Pdb().set_trace def buggy_method(): debug()

Run django-admin help --commands to display a list of all available commands.,Run django-admin help to display usage information and a list of the commands provided by each application.,Run django-admin help <command> to display a description of the given command and a list of its available options.,command should be one of the commands listed in this document. options, which is optional, should be zero or more of the options available for the given command.

$ django-admin <command> [options]
   $ <command> [options]
      $ python -m django <command> [options]

From vim, breakpoints can be set on a python file and ipdb is used for debugging using a the tmux mutiplexer. As the user is debugging the file, the current line is shown within vim.,Breakpoints can be toggled on/off with ;; and the breakpoint list can be toggled on/off using ;b. To run a file under the ipdb debugger use ;r which opens a pane containing an ipdb terminal. See pdb manual for a list of commands.,The debugger works by opening a standard ipdb terminal as a tmux pane directly below the vim pane. This allows for the ipdb debuger to be able to interact with vim files and eases setting breakpoints and viewing code around the currently executed line.,Breakpoitns are stored in a .pdbrc file in the project directory so that breakpoitns can persists between vim sessions. Note that breakpoints can also be set and removed from within the ipdb terminal and they are updated accordingly in vim.
