$ show shortcuts/no-neck-pain.nvim
no-neck-pain.nvim is a Neovim plugin that centers the focused buffer in the middle of the screen by creating empty side buffers. It provides a non-opinionated, highly configurable zen-like editing experience without the intrusive UI changes typical of other 'distraction-free' plugins. The plugin manages window layout across multiple tabs, supports splits/vsplits, and integrates with popular file trees (NvimTree, Neo-tree), dashboards (alpha, snacks), and other tools like undotree, neotest, nvim-dap-ui, outline, and aerial. The architecture is modular Lua with clear separation into configuration, state management, UI creation, color handling, and utility modules. The core logic revolves around dynamic layout scanning via Neovim's winlayout API, event-driven re-initialization, and per-tab state tracking.
The LLM identified 2 files worth highlighting for reuse:
Provides pure functions for hex color parsing, blending (brighten/darken), and validating/mapping theme names to hex codes. The `hex_to_rgb`, `blend`, and `match_and_blend` functions are self-contained, reusable, and demonstrate solid handling of color arithmetic and format validation. They can be extracted and used in any Lua-based color processing utility, not just within the plugin.
Contains a well-crafted debounce implementation using `vim.loop` timers that correctly handles cancellation, re-scheduling during execution, and cleanup. This is a non-trivial pattern in Neovim plugin development, avoiding race conditions and redundant re-initializations. The function is parameterized over context and callback, making it reusable across other plugins needing debounced event handling. Also provides helper functions for setting buffer/window options with backward compatibility (pre-0.9 Neovim).
