I have been trying to get dap-mode for c++ to work. Below is my config related to dap-mode
(use-package dap-mode
:after lsp-mode
:commands dap-debug
:hook ((c++-mode python-mode . dap-ui-mode) (python-mode . dap-mode))
:config
(dap-auto-configure-mode t)
(setq dap-python-debugger 'debugpy)
(require 'dap-python)
(require 'dap-gdb-lldb)
(require 'dap-lldb)
(setq dap-lldb-debug-program "/usr/bin/lldb-vscode")
;;; ask user for executable to debug if not specified explicitly (c++)
(setq dap-lldb-debugged-program-function (lambda () (read-file-name "Select file to debug.")))
;;; default debug template for (c++)
(dap-register-debug-template
"C++ LLDB dap"
(list :type "lldb-vscode"
:cwd nil
:args nil
:request "launch"
:program nil))
;; (defun dap-python--pyenv-executable-find (command)
;; (with-venv (executable-find "python")))
(add-hook 'dap-stopped-hook
(lambda (arg) (call-interactively #'dap-hydra)))
(defun dap-debug-create-or-edit-json-template ()
"Edit the C++ debugging configuration or create + edit if none exists yet."
(interactive)
(let ((filename (concat (lsp-workspace-root) "/launch.json"))
(default "~/.config/emacs/default-launch.json"))
(unless (file-exists-p filename)
(copy-file default filename))
(find-file-existing filename))))
The problem I am facing currently is that every time i run
dap-debug
while the file is open i get prompted for executable and when i select the candidate, I get the error
Wrong type argument: stringp, nil
From what I learned we get the above error when a function get a nil value while expecting a string but I don’t understand why the function will get a nil value when i selected the correct executable with appropriate compiler flags.
I would appreciate any help in the matter.
