* Dependencies

** Required
- =git= - For plugin management
- =vim= - 8.0+ recommended
- =ripgrep= (=rg=) - Fast grep alternative for FZF
- =fd= - Fast find alternative for FZF
- =fzf= - Fuzzy finder

** Optional
- =rust-analyzer= - Rust LSP server
- =typescript-language-server= - TypeScript/JavaScript LSP
- =intelephense= - PHP LSP

** Installation

*** Arch Linux
#+begin_src bash
sudo pacman -S git vim ripgrep fd fzf
sudo pacman -S rust-analyzer  # optional
npm install -g typescript-language-server  # optional
#+end_src

*** NixOS
#+begin_src bash
nix-env -iA nixpkgs.git nixpkgs.vim nixpkgs.ripgrep nixpkgs.fd nixpkgs.fzf
nix-env -iA nixpkgs.rust-analyzer  # optional
npm install -g typescript-language-server  # optional
#+end_src

*** Gentoo
#+begin_src bash
sudo emerge --ask dev-vcs/git app-editors/vim sys-apps/ripgrep sys-apps/fd app-shells/fzf
sudo emerge --ask dev-lang/rust-bin  # for rust-analyzer
npm install -g typescript-language-server  # optional
#+end_src

*** Linux (Debian/Ubuntu)
#+begin_src bash
sudo apt install git vim ripgrep fd-find fzf
# Note: fd is called fd-find on Debian/Ubuntu
#+end_src

*** macOS
#+begin_src bash
brew install git vim ripgrep fd fzf
brew install rust-analyzer  # optional
npm install -g typescript-language-server  # optional
#+end_src

*** Rust Analyzer
#+begin_src bash
rustup component add rust-analyzer
#+end_src

* Setup

** 1. Clone or copy your Vim configuration
#+begin_src bash
git clone <your-repo> ~/.vim
#+end_src

** 2. Configure Bash/Zsh
Add to =~/.bashrc= or =~/.zshrc=:

#+begin_src bash
export FZF_DEFAULT_COMMAND='fd --type f --hidden --follow'
#+end_src

Then source your shell config:
#+begin_src bash
source ~/.bashrc  # or ~/.zshrc
#+end_src

** 3. Configure fd ignore file
Create =~/.fdignore=:

#+begin_src bash
vim ~/.fdignore
#+end_src

Add these lines:
#+begin_src
undodir/
plugged/
.git
#+end_src

** 4. Configure ripgrep ignore file
Create =~/.rgignore=:

#+begin_src bash
vim ~/.rgignore
#+end_src

Add the same patterns:
#+begin_src
undodir/
plugged/
.git
#+end_src

** 5. Install plugins
Open Vim and the plugins will auto-install on first run.

* Plugin List

| Plugin                  | Purpose                           |
|-------------------------+-----------------------------------|
| =junegunn/fzf=          | Fuzzy finder                      |
| =junegunn/fzf.vim=      | FZF Vim integration               |
| =tomasiser/vim-code-dark= | Code Dark color scheme          |
| =ghifarit53/tokyonight-vim= | Tokyo Night color scheme      |
| =yegappan/lsp=          | LSP client                        |
| =ojroques/vim-oscyank=  | Copy to system clipboard via OSC52|
| =tpope/vim-commentary=  | Comment/uncomment code            |
| =itchyny/lightline.vim= | Statusline                        |

* File Structure

#+begin_example
~/.vim/
├── vimrc           # Main config (sources all below)
├── options.vim     # Vim options and settings
├── keybinds.vim    # Keybindings
├── plugins.vim     # Plugin manager and plugin list
├── colors.vim      # Color scheme configuration
├── fzf.vim         # FZF configuration
├── lightline.vim   # Lightline configuration
└── plugged/        # Plugin installation directory
#+end_example

* Usage

** Installing Plugins
Plugins auto-install when you first start Vim. To manually reinstall, delete =~/.vim/plugged= and restart Vim.

** Updating Plugins
#+begin_src bash
cd ~/.vim/plugged/<plugin-name>
git pull
#+end_src

** FZF File Search
The FZF configuration respects =.gitignore=, =.fdignore=, and =.rgignore= files automatically.

Use =<leader>ff= to search files, =<leader>fg= to grep content.

** LSP Servers
Configure LSP servers in your config. Currently configured:
- Rust: =rust-analyzer=
- TypeScript/JavaScript: =typescript-language-server=
- PHP: =intelephense=

* Notes

- The plugin manager is custom and minimal - it auto-installs plugins on Vim startup
- =.fdignore= and =.rgignore= prevent searching through plugin directories and undo files
- FZF uses =fd= for file listing (faster than =find=) and =rg= for content search
- OSCYank allows copying to system clipboard even over SSH
