nvim-dap-virtual-text
A Neovim plugin that displays debugger variable values as virtual text during debugging sessions.
What is nvim-dap-virtual-text?
nvim-dap-virtual-text is a Neovim plugin that extends nvim-dap by displaying variable values as virtual text directly in the code editor during debugging sessions. It solves the problem of constantly switching between code and debugger consoles to inspect variable states, making debugging more efficient and visual.
Neovim users who regularly debug code with nvim-dap and want a more integrated, visual debugging experience without leaving their editor.
Developers choose this plugin because it provides immediate visual feedback on variable states during debugging, reduces context switching, and offers extensive customization to fit individual workflows, all while leveraging the powerful nvim-treesitter ecosystem for accurate variable detection.
Overview
nvim-dap-virtual-text enhances the debugging experience in Neovim by showing variable values inline as virtual text while using nvim-dap. It integrates with nvim-treesitter to intelligently locate variable definitions and references, making debugging more visual and efficient.
Key Features
- Inline Variable Display — Shows variable values directly in the code as virtual text during debugging.
- Changed Value Highlighting — Highlights variables that have changed since the last step with customizable colors.
- Exception Stop Reasons — Displays the reason for debugger stops due to exceptions.
- Multi-language Support — Works with any language supported by nvim-treesitter's locals.scm queries (C/C++, Python, Rust, Go, Java, etc.).
- Customizable Display — Offers extensive configuration options for virtual text position, formatting, and behavior.
- Frame-aware Display — Can show variable values from all stack frames, not just the current one.
Philosophy
The plugin follows a minimalistic approach, enhancing the debugging workflow without cluttering the interface, and leverages existing Neovim ecosystems like nvim-treesitter for intelligent parsing.
