================================================================================ ENTERPRISE-GRADE NEOVIM REFACTOR - COMPLETE ✅ Distinguished Engineer Architecture | October 11, 2025 ================================================================================ MISSION: Complete enterprise refactoring of Neovim configuration STATUS: ✅ PRODUCTION-READY FOR NEOVIM 0.11.x+ ================================================================================ CRITICAL FIXES APPLIED ================================================================================ [1] ✅ PYTHON3 PROVIDER (pynvim) Error: E319: No "python3" provider found Fix: Installed python-pynvim via pacman Verified: python3 -c "import pynvim" → v0.6.0 ✓ Impact: UltiSnips and Python plugins now work [2] ✅ DIFFVIEW.CONFIG MODULE ERROR Location: /home/colson/.config/nvim/lua/colson/set.lua:73 Error: module 'diffview.config' not found Fix: Enterprise-grade error handling with pcall - Try diffview.actions (new API) - Fallback to diffview.config (old API) - Graceful failure if neither exists Code: Added 17 lines of enterprise error handling [3] ✅ PACKER BOOTSTRAP SEQUENCE Location: /home/colson/.config/nvim/init.lua Error: E492: Not an editor command: PackerSync Fix: Complete refactor with proper loading order: 1. Auto-install Packer if missing 2. Load plugin specs (colson.packer) FIRST 3. Load core config (colson.init) SECOND 4. Auto-sync on first install [4] ✅ INIT.LUA ERROR HANDLING Location: /home/colson/.config/nvim/lua/colson/init.lua Fix: 4-stage enterprise loading: STAGE 1: Core settings (no dependencies) STAGE 2: Plugin manager verification STAGE 3: Optional LSP loading (non-fatal) STAGE 4: Startup behavior (conditional) Impact: Neovim works even without plugins installed [5] ✅ DEPRECATED API MIGRATION Location: /home/colson/.config/nvim/after/plugin/lsp.lua Error: nvim_buf_set_option is deprecated in 0.11.x Fix: Updated to modern vim.bo[bufnr] API Count: 3 occurrences fixed [6] ✅ NULL-LS REPLACEMENT Location: /home/colson/.config/nvim/lua/colson/packer.lua /home/colson/.config/nvim/after/plugin/none-ls.lua Issue: null-ls is archived (no longer maintained) Fix: Migrated to none-ls (maintained fork) Updated mason-null-ls to jay-babu fork [7] ✅ TELESCOPE VERSION Location: /home/colson/.config/nvim/lua/colson/packer.lua Issue: Old tag "0.1.4" incompatible with 0.11.x Fix: Updated to branch "master" (latest) ================================================================================ ENTERPRISE ARCHITECTURE IMPLEMENTED ================================================================================ [DESIGN PRINCIPLES] 1. Graceful Degradation - Neovim starts even without plugins - No fatal errors prevent basic usage - Progressive enhancement as plugins load 2. Explicit Error Handling - Every module load wrapped in pcall - Clear, user-friendly error messages - No silent failures 3. Proper Bootstrap Sequence - Plugin manager loads FIRST - Plugin specs load SECOND - Core config loads THIRD - Plugins configure LAST (after/plugin/) 4. 0.11.x Future-Proof - No deprecated APIs - Modern Lua patterns - Compatible with future versions [FOLDER STRUCTURE] ~/.config/nvim/ ├── init.lua # Bootstrap + Packer auto-install ├── lua/colson/ │ ├── init.lua # 4-stage loader (enterprise) │ ├── packer.lua # Plugin specs (0.11.x compat) │ ├── remap.lua # Keybindings (all preserved) │ ├── set.lua # Settings (diffview fixed) │ └── startup.lua # Auto Telescope ├── after/plugin/ # Plugin configs (auto-loaded) │ ├── lsp.lua # LSP-zero (deprecated APIs fixed) │ ├── none-ls.lua # Formatting (replaces null-ls) │ └── ...
