dap-mode is an Emacs client and library for the Debug Adapter Protocol (DAP), providing integrated debugging inside Emacs similar to how lsp-mode integrates language servers. It supports many languages including Java, Python, Ruby, Elixir, and C/C++/Swift via LLDB, with features like debug templates, a hydra keymap, and Docker-based debug server support.

Use cases

• debug programs from within emacs
• set breakpoints and step through code in emacs
• debug java python ruby elixir in emacs
• use debug adapter protocol in emacs
• debug c++ with lldb in emacs
• debug code running in docker from emacs

When to choose

• you use Emacs as your primary editor and want an integrated graphical debugger
• you want DAP-based debugging across multiple languages with a consistent interface
• you need to debug applications running in Docker containers from Emacs

When to avoid

• you use VS Code or another editor with built-in DAP support
• you need a stable, guaranteed API before the 1.0 release
• you need to connect to debuggers over a network connection, which is not yet supported
