What's Included

• Neovim: Lua configuration with LSP, treesitter, and WSL clipboard integration
• Tmux: Terminal multiplexer with Vim-style navigation and session persistence
• Zsh: Shell configuration with Oh-My-Zsh, aliases, and developer tooling setup
• Bash: Utility scripts, color-coded logging, and environment detection
• WSL Integration: Seamless clipboard sharing between Ubuntu and Windows

Quick Setup

# Clone the repository
git clone https://github.com/Unique-Divine/dotfiles.git
cd dotfiles

# Install system packages used by the shell and Neovim.
# - build-essential: Used in almost everything
# - gh: GitHub CLI
# - libclang-dev: Needed so `cargo install tree-sitter-cli` can build.
# - tree-sitter-cli: Required by `nvim-treesitter` on the `main` branch.
# - wslu: Provides `wslview` (Example: gh pr view --web). This fixes the error,
#   > exec: "xdg-open,x-www-browser,www-browser,wslview": executable file not found in $PATH

sudo apt install build-essential ripgrep gh libclang-dev wslu

# This might be different for you. The command comes from here: 
# https://rustup.rs/
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh 
cargo install just
cargo install bat tree-sitter-cli sd

# Create symbolic links for configurations
source zsh/zshenv # internally runs $DOTFILES/symlinks.sh

# Install development tools
bun install
just setup

After installing nvim, restore Neovim plugins from the lazy.nvim lockfile:

nvim --headless "+Lazy! restore" +qa

Symlink Philosophy

This dotfiles repo uses symbolic links to maintain a single source of truth for all configurations. The advantages of this approach include:

• Version control: Track changes to your configurations over time
• Portability: Quickly set up identical environments across machines
• Centralization: Modify configs in one place and have changes propagate
• Safety: Original system files aren't modified, only linked to
• Maintenance: Updates to the repo instantly apply to all linked machines

The symlinks.sh script handles creating all necessary symbolic links to connect the configurations in this repo to their expected locations in your home directory and .config folder.

Features

Sync and health checks

just sync runs the established shell bootstrap, applies portable Codex defaults, and synchronizes managed AI skills. just health does not write: it checks required commands and reports Codex or skills-sync drift with a nonzero exit status.

AI agent skills

just skills-sync --run treats $HOME/.cursor/skills as the canonical runtime directory and also copies all skills to $HOME/.agents/skills for Codex CLI. The Codex destination is created and marked as managed on first use; an existing unrelated non-empty directory is rejected rather than overwritten.

See the Codex skills documentation.

Neovim Configuration

• Light/dark theme toggle (Catppuccin/OneDark)
• Treesitter with support for modern languages including Astro
• LSP with auto-installation of language servers
• Harpoon, Telescope, and other navigation enhancements

Terminal Environment: tmux, zsh, bun

• Tmux with Dracula theme and plugin manager
• Zsh configured for Node.js, Rust, Go, and Python development
• Bun JavaScript/TypeScript runtime integration
• tree-sitter-cli support for Neovim parser installation on the main branch

Herdr configuration

herdr/config.toml is the managed configuration source. symlinks.sh links only this file to ~/.config/herdr/config.toml; Herdr's sessions and logs remain runtime-owned and are never linked or versioned. Like the existing dotfiles links, sync replaces the runtime config with this managed source. Backup/preservation or force-mode policies are deferred.

The checked-in file is the complete annotated baseline generated by Herdr 0.8.0. Its options are commented except for upstream's explicit pane_history = false default, so it preserves built-in behavior until an option is deliberately changed. Refresh it only when deliberately adopting a new Herdr baseline:

herdr --default-config

The upstream source is available as the pinned lib-herdr submodule for local documentation and implementation inspection. Initialize it after cloning dotfiles with git submodule update --init --recursive.

Codex config

codex/config.ts maintains portable defaults in $HOME/.codex/config.toml while preserving local project and onboarding state. When present, $HOME/.cursor/mcp.json supplies same-named MCP servers; other Codex MCP servers remain local. Run bun run codex/config.ts for its usage and options.

WSL Clipboard Integration

• A persistent Rust bridge that keeps one PowerShell clipboard process warm
• pbcopy, pbpaste, wsl-pbcopy, and wsl-pbpaste are symlinks to the one installed bridge binary; it dispatches by the command name
• Lossless UTF-8 text across the WSL/Windows boundary, including emoji and non-BMP Unicode; PowerShell performs the internal UTF-16 conversion
• just sync installs ~/.local/bin/wsl-clipboard on WSL; its daemon starts only on the first copy or paste request
• legacy-pbcopy and legacy-pbpaste retain the old one-shot commands for diagnostics and performance comparison

Requirements

• Ubuntu 24.04 (or compatible) on WSL2
• Neovim v10.0.4+ (ARM64 AppImage included)
• Zsh with Oh-My-Zsh
• Tmux
• Bun and Node.js
• Cargo/Rust tools
• Just command runner (cargo install just)
• libclang-dev for building tree-sitter-cli
• lua5.1 and luarocks for Lazy/LuaRocks health checks
• tree-sitter-cli (cargo install tree-sitter-cli)

Testing
