help setting up lldb-vscode for cpp

[p00f]

Thank you for the excellent step-by-step wiki, but unfortunately I still have problems 😅

init.lua:

local api = vim.api

api.nvim_command('packadd packer.nvim')
api.nvim_set_option("termguicolors", true)
api.nvim_set_var("oak_virtualtext_bg", 1)
api.nvim_set_var("conjure#mapping#doc_word", ",K")

local packer = require('packer')
local packages = require('packages')

packer.startup(function()
  for _, value in pairs(packages) do
    packer.use(value)
  end
end)

vim.cmd [[
    command! -complete=file -nargs=* DebugC lua require "dap_setup".start_c_debugger({<f-args>}, "gdb")
]]

lua/dap_adapters.lua:

local dap = require "dap"
dap.adapters.cpp = {
  type = "executable",
  attach = {
    pidProperty = "pid",
    pidSelect = "ask"
  },
  command = "lldb-vscode", -- my binary was called 'lldb-vscode-11'
  env = {
    LLDB_LAUNCH_FLAG_LAUNCH_IN_TTY = "YES"
  },
  name = "lldb"
}

lua/dap_setup.lua:

-- In a file lua/my_debug.lua
local M = {}
local last_gdb_config

M.start_c_debugger = function(args, mi_mode, mi_debugger_path)
  local dap = require "dap"
  require "dap_adapters"
    if args and #args > 0 then
        last_gdb_config = {
            type = "cpp",
            name = args[1],
            request = "launch",
            program = table.remove(args, 1),
            args = args,
            cwd = vim.fn.getcwd(),
            env = {"VAR1=value1", "VAR2=value"}, -- environment variables are set via `ENV_VAR_NAME=value` pairs
            externalConsole = true,
            MIMode = mi_mode or "gdb",
            MIDebuggerPath = mi_debugger_path
          }
    end

    if not last_gdb_config then
        print('No binary to debug set! Use ":DebugC <binary> <args>" or ":DebugRust <binary> <args>"')
        return
    end

    dap.run(last_gdb_config)
    --dap.repl.open()
end

return M

:DebugC solution.cpp "hi" gives

How about compiling your source file? You also have to compile with -g.

I compiled it from the parent directory with clang++ Day1/solution.cpp -g, and then did :Debugc ../a.out "hi", nothing happens:

recording.mp4

[theHamsta]

Did you try setting a break point? Or opening the dap.repl in your Lua function? Your short programm will probably finish to run very quickly.

I guess this also tells lldb to print all output in the dap repl.

LLDB_LAUNCH_FLAG_LAUNCH_IN_TTY = "YES"

[p00f]

sorry i'm new, does this have to be a shell environment variable?

[theHamsta]

I copied in from your config (your lua/dap_adapters.lua)

[p00f]

yeah including the repl in the function prints what was supposed to be printed, thanks. I'll read some more
