dap-mode

Table of Contents

Summary

Emacs client/library for Debug Adapter Protocol is a wire protocol for communication between client and Debug Server. It’s similar to the LSP but provides integration with debug server.

Project status

The API considered unstable until 1.0 release is out. It is tested against Java, Python, Ruby, Elixir and LLDB (C/C++/Objective-C/Swift).

Usage

The main entry points are dap-debug and dap-debug-edit-template. The first one asks for a registered debug template and starts the configuration using the default values for that particular configuration. The latter creates a debug template which could be customized before running. dap-debug-edit-template will prepare a template deceleration inside a temporary buffer. You should execute this code using C-M-x for the changes to apply. You should also copy this code into your Emacs configuration if you wish to make it persistent.

dap-mode also provides a hydra with dap-hydra. You can automatically trigger the hydra when the program hits a breakpoint by using the following code.

(add-hook 'dap-stopped-hook
          (lambda (arg) (call-interactively #'dap-hydra)))
