nvim-agentic-devenv

Terminal-native development environment built on Neovim, tmux, and Ghostty. Replaces VSCode + devcontainers with hand-rolled, transparent config.

• Linting (nvim-lint) — eslint, golangci-lint; Python/Rust/Elixir/C# via LSP
• Diagnostics panel (trouble.nvim), TODO highlighting, auto-pairs
• Debugging (nvim-dap) — DAP UI, virtual text, Python debugpy, Mason adapter install
• Test runner (neotest) — inline pass/fail, adapters for Python, Rust, Go
• Git integration — gitsigns (hunk navigation/staging), lazygit (floating terminal)
• Navigation — telescope (fuzzy finder), flash.nvim (jump), aerial (code outline)
• Editing — mini.surround, mini.ai textobjects, treesitter textobjects, inc-rename (live preview)
• Refactoring — extract function/variable, inline variable
• Search and replace — grug-far.nvim (project-wide)
• UI — neo-tree (file explorer), bufferline (tabs), lualine (statusline with breadcrumbs), which-key, indent guides, dashboard
• Sessions — auto-save/restore per directory (persistence.nvim)
• Markdown rendering in-editor (render-markdown.nvim)
• AI assistant (devenv-agent) — inline chat with explain/do modes, Ollama (local) or Anthropic providers
• Tokyodark color scheme with Nerd Font icons

Terminal multiplexer (tmux)

• Ctrl-a prefix, window switching via Alt+1-9

Terminal emulator (Ghostty/iTerm2)

• Cmd+1-9 mapped to Alt+1-9 for tmux window switching

Requirements

• macOS (Homebrew)
• Ghostty or iTerm2
• A Nerd Font (the Brewfile installs one)

Quick start

git clone https://github.com/ondrasek/nvim-agentic-devenv.git
cd nvim-agentic-devenv
make install

This runs the full bootstrap: installs Homebrew packages, CLI tools, and copies configs to ~/.config/.

Makefile targets

make install        # Full bootstrap (brew, tools, copy configs)
make copy           # Copy configs only (no brew install)
make diff           # Show differences between repo and installed configs
make setup-project  # Init current dir as dev project

Configs are copied (not symlinked). Use chezmoi to track installed dotfiles — the bootstrap script detects it automatically.
