How to set 'justMyCode=false' via dap when debug a python program?

[weiyshay]

Hi,
Thank you for your feedback!

I am debugging a python program and want to trace into the library which needs to set the 'justMyCode' option in debugpy to 'false'.

I searched around and found a link which is not accessable, so I pasted the snapshot here. My question is how I can set this option in my lua plugin.

My python dap config:

local dap = require('dap')

dap.adapters.python = {
    type = "executable",
    -- command = "/localdata/weix/env/virtual-env/centos76-tf793/bin/python3",
    command = "python3",
    args = { "-m", "debugpy.adapter" },
}

local get_args = function()
  -- 获取输入命令行参数
  local cmd_args = vim.fn.input('CommandLine Args:')
  local params = {}
  -- 定义分隔符(%s在lua内表示任何空白符号)
  local sep = "%s"
  for param in string.gmatch(cmd_args, "[^%s]+") do
    table.insert(params, param)
  end
  return params
end

dap.configurations.python = {
  {
    type = "python", -- the type here established the link to the adapter definition: `dap.adapters.python`
    request = 'launch',
    name = 'launch file',
    -- 此处指向当前文件
    program = '${file}',
    args = get_args,
    pythonPath = function()
        local venv_path = os.getenv("VIRTUAL_ENV")
        if venv_path then
        return venv_path .. "/bin/python"
        end
        return "/usr/bin/python3"
    end
  },
}

debugpy.nvim: Command and API frontend to nvim-dap and Debugpy (debugging Python)

Hi there,

I use Python quite a lot and when I debug the code I want to be able to quickly specify what I want to debug and not have to manually create individual debugger configurations for each project. So I made a plugin that does it for you: [debugpy.nvim](https://gitlab.com/HiPhish/debugpy.nvim) ([GitHub mirror](https://github.com/HiPhish/debugpy.nvim)). It provides a thin layer on top of [nvim-dap](https://github.com/mfussenegger/nvim-dap).

I am a very big fan of the way nvim-dap is structured: it is basically just a Lua library with a reasonable minimum of UI, and it is really easy to build plugins on top of that. Debugpy.nvim provides a new command :Debugpy which allows you to specify a sub-command (currently module, program or attach) and arguments, and it will launch the debugger for you. Example:

" Debug a module with command-line arguments
Debugpy module main foo bar

" Attach to a running process
Debugpy attach 127.0.0.1 5678

Even if you don't like the command you can still use the API, which supports Lua and Vim script:

local debugpy = require 'debugpy'
local config = debugpy.configure('module', 'main', 'foo', 'bar')
debugpy.run(config)

You can define your own sub-commands and override the run function to alter how the debugger is started or to inject your own debugger settings. No setup function or other nonsense, just pure Lua and Vim script:

-- Your personal default settings
default = { justMyCode = false }

-- Implementation which injects your default settings
require('debugpy').run = function(config)
    local final = vim.tbl_extend('keep', config, default)
    require('dap').run(final)
end

I have been using this for a couple of months in my configuration, and now I have turned it into a proper plugin. I hope you enjoy it as well. And hey, it even comes with an actual manual! (sorry, I just had to make that jab)

Just Insert entry [justMyCode, false] into dap.configurations.python table like below:
This works for me.

dap.configurations.python = {
  {
    justMyCode = false, -- <--- insert here
    type = "python", -- the type here established the link to the adapter definition: `dap.adapters.python`
    request = 'launch',
    name = 'launch file',
    -- 此处指向当前文件
    program = '${file}',
    args = get_args,
    pythonPath = function()
        local venv_path = os.getenv("VIRTUAL_ENV")
        if venv_path then
        return venv_path .. "/bin/python"
        end
        return "/usr/bin/python3"
    end
  },
}

I solved it by changing my key bindings that run the tests. test_method and test_class receive an opts parameter.

lvim.keys.normal_mode["<leader>dm"] = ":lua require('dap-python').test_method({ config = { justMyCode = false } })<CR>"
lvim.keys.normal_mode["<leader>dl"] = ":lua require('dap-python').test_class({ config = { justMyCode = false } })<CR>"

Can launchMyCode be conditioned on the launch.json file? It doesn't seem to be respected.
