Nvim Dap
nvim-dap is a Neovim plugin that serves as a client implementation of the Debug Adapter Protocol. It provides a language-agnostic debugger interface that integrates external debugger binaries into the editor, allowing users to manage breakpoints and step through code.
The project enables remote process debugging by attaching to running processes or containerized applications via TCP sockets and network proxies. It supports connecting to debug adapters through standard input/output or TCP, with specialized support for launching and attaching to Java processes.
The plugin covers program execution control through breakpoint management, interactive stepping, and the ability to launch debug sessions for specific test methods or classes. It also provides state inspection capabilities, including expression evaluation and the visualization of variable values via virtual text overlays.
Features
