Vimspector

vimspector is a powerful debugging plugin for Vim and Neovim designed to bring IDE-style debugging capabilities (breakpoints, stepping, call stacks, watch windows) into the modal editor world. It supports multiple languages (C++, Python, TCL among others) via the Debug Adapter Protocol (DAP) model and provides an in-editor UI for viewing scopes, variables, stack frames, output windows and more. You configure it per-project via a .vimspector.json file (or per file type) specifying the adapter, launch configuration or attach process. Once configured you can run, pause, step into/out/over, set and clear breakpoints and inspect variables directly in Vim splits or floating windows. The UI is heavy compared to typical Vim plugins (multiple panes, layouts) but it fills the gap for users who want an integrated debug workflow without leaving the editor.
