(Optional) To have IntelliSense for debugpy on your local computer, install the debugpy package into your Python environment. It doesn't matter where the file is located, but its name should match the name of the script on the remote computer. In these steps, we set a simple breakpoint to stop the remote process.Ĭreate a copy of the remote file on the local computer and open it in Visual Studio. There is also an is_client_connected function that returns True if the debugger is attached (note that there is no need to check this result before calling any other debugpy functions). In addition to listen and wait_for_client, debugpy also provides a helper function breakpoint, which serves as a programmatic breakpoint if the debugger is attached. Install the debugpy package into your environment using pip3 install debugpy. Name = input('Hello! What is your name?\n') On the remote computer, create a Python file called guessing-game.py with the following code: import random Ubuntu for the VM is convenient because Python is installed by default otherwise, see the list on Install a Python interpreter of your choice for additional Python download locations.įor details on creating a firewall rule for an Azure VM, see Open ports to a VM in Azure using the Azure portal. You can easily create a Linux virtual machine on Azure and access it using Remote Desktop from Windows. I hope this will help anybody get started with pdb.This walkthrough is based on Visual Studio 2019 version 16.6. If you no longer need a breakpoint, you can clear it by passing in the id of the breakpoint with the clear command: (Pdb) clear 1įinally, when you are done with the debugger you can exit the execution as you would exit the python command line interpreter. If you want to examine the values of variables, you would execute the parameter command as follows: (Pdb) p variable_name Once you get to a breakpoint you could go to the next line, with the n command as described before. Once a breakpoint is set, you would continue executing your program until pdb gets to the breakpoint as follows: (Pdb) c If you add more break points they will get identifiers sequentially (i.e., 2, 3 etc.) If there aren't any other breakpoints, the breakpoint at line 50 will be the first and it could be referenced by the breakpoint id which is 1 in this case. Here, the debugger is set to break at line 50. You can set a breakpoint by specifying a line number in your source code. Performing a next would display the line number, and the specific code in the source: > python_script(line number)method name You can go to the next line in your code by command "n" (next): (Pdb) n Opposed to using buttons or keyboard shortcuts in visual debuggers, here you will use commands to derive the same results. This is the interface for communicating with the debugger. This command initializes pdb and the pdb debugger will break at the first line of your python_script and wait for an input from you: (Pdb) Start pdb by typing the following in a shell prompt: python -m pdb 'python_script' This is how you would use pdb in the command line without implementing anything in your source code (the documentation and other online resources don't do a good job explaining this to a programmer who has only used visual debuggers in the past): I think it would be possible to use better autocommands to do this - but I couldn't get it to work as reliably as this. Then this is easily extendible to other languages too. So I get either the ipdb breakpoint, or other language breakpoints in those languages. So I'm doing a lot of django these days, I'm using the ipdb debugger also, with some javascript and some HTML templating, so now have: function InsertDebug()Įxecute "normal! oimport ipdb t_trace()\"Įlseif &filetype = "html" || &filetype = "htmldjango"Įxecute "normal! o\4bcw"Įchoerr "Unknown filetype - cannot insert breakpoint" Python 3.7+ now has the builtin breakpoint() which can replace the previous import pdb pdb.set_trace() in vim. You could very easily add similar lines for javascript or whatever other languages you use. Which turns it on only for python source files. I actually have: au FileType python map b oimport pdb pdb.set_trace()Īu FileType python map B Oimport pdb pdb.set_trace() Most other 'simple' programmers editors (emacs, sublimetext, etc) should have similar easy ways to do this. So I can just press \b (when not in Insert Mode) and it adds in a breakpoint after the current line, or \B (note the capital) and it puts one before the current line. vimrc file): map b oimport pdb pdb.set_trace() In vim, I have a macro set up for this (in my.
