## What it is
nvim-dap is a Debug Adapter Protocol (DAP) client implementation for Neovim, written in Lua. It lets users launch or attach to applications, set breakpoints, step through code, and inspect program state from within the editor, supporting any language with an available debug adapter.

## Use cases
- debug python code inside neovim
- set breakpoints and step through code in vim
- attach debugger to a running process from neovim
- inspect variables and evaluate expressions during debugging
- debug c++ with gdb or lldb in neovim
- set up a dap client for go delve debugging
- replace vscode debugging with neovim

## When to choose
- you use Neovim as your primary editor and want integrated debugging
- you want a lightweight, extensible DAP client configurable per language
- you prefer terminal-based workflows over IDEs like VS Code

## When to avoid
- you want a full IDE-like debug UI out of the box (pair it with nvim-dap-ui instead)
- you use an editor other than Neovim
- no debug adapter exists for your language

## Facets
- artifact type: plugin
- maturity: stable
- function: developer-tools, editor
- domain: developer-tools, text-editors
- platform: editor-plugin, windows
- tags: neovim, debug-adapter-protocol, debugger, lua, vim-plugin, debugging, linux, macos
