But, if there's an aspect of development that emacs has struggled with, that is, in my opinion, debugging. -(Although the C/C++ development experience in emacs remains uncontested). - -{: width="800" } - -The developers of the aforementioned lsp-mode also mantain dap-mode, a DAP (LSPs but for debuggers) client for emacs. But -as you can already guess, it needs lsp-mode, much to the chagrin of eglot users. - -But now we have a competitor to dap-mode in the same way that eglot is a competitor to lsp-mode. [Dape](https://github.com/svaante/dape) -(which isn't that new to be honest, with its first commit dating back to september 29th, 2023). - -Unlike dap-mode, it strives to be a minimalist dap client, and it doesn't make use of a launch.json file, relying instead on configurations -written totally in elisp. - -In this post, I'll show an example configuration to use dape with python and flask, but I plan on updating it with more configurations. -Dape is an extremely interesting project and the fact that it's compatible with ruby's rdbg debug gem catched my eye: emacs can't compete -right now with vs code as the development environment for ruby, mainly because of debugging. I haven't had luck configuring dap-mode's ruby -debug mode and it doesn't use rdbg, which is the newest, most up to date, and overall, best gem for debugging ruby. I also would like to check -debugging vanilla javascript. - -But anyway, reading dape's source code we come across this: - -```elisp -command "python" - command-args ("-m" "debugpy.adapter" "--host" "0.0.0.0" "--port" :autoport) - port :autoport - :request "launch" - :type "python" - :cwd dape-cwd)) - (common - `(:args [] - :justMyCode nil - :console "integratedTerminal" - :showReturnValue t - :stopOnEntry nil)) -``` - -This is the python debugpy configuration. When you install dape, and run it with `M-x dape`, you can select this config. -And you can assign all the variables you need in order to debug your flask project, mainly, `:args` and `:module`. -But it's not practical to type all of that everytime you wish to debug your project, so let's jump to your init.file, -and write the following: - -```elisp -(require 'dape) -;; Dape configs -(add-to-list 'dape-configs - `(debugpy-flask - modes (python-mode jinja2-mode) - command "python" - command-args ["-m" "debugpy.adapter" "--host" "0.0.0.0" "--port" :autoport] - port :autoport - :type "python" - :request "launch" - :module "flask" - :args ["--app" "src" "run" "--no-debugger" "--no-reload"] - :console "integratedTerminal" - :showReturnValue t - :justMyCode nil - :jinja t - :cwd dape-cwd-fn)) -``` - -First, we load dape, and then, add another config to the dape-configs list, defined in dape.el. -As you can see, it is kind of a shameless copy paste of dape's base debugpy config, but with every variable -set for flask development, like the module to be used (flask) and the CLI arguments it uses (--app, run, etc.) -There's an issue though, as you can see, the args array defines my app's name as "src", I tried to refer to my app's -name as a variable, so it could be used for different projects, but alas, I'm not too familiar with dape, or elisp for that matter. -A possible solution is just to copy this to a .dir-locals.el file for a project wide configuration. |
