# Emacs Configuration

Personal Emacs configuration focused on simplicity and modern tooling while respecting default Emacs keybindings.

## Philosophy

- Clean and minimal configuration

- Prefer built-in Emacs functionality when possible

- Use modern, actively maintained packages

- Respect default Emacs keybindings

- Single `init.el` file for simplicity

## Structure

```

~/.emacs.d/

├── init.el           # Main configuration file

├── elisp/            # Custom configuration modules

│   ├── c-init.el     # C/C++ configuration

│   └── ansible-init.el # Ansible/YAML configuration

└── README.md         # This file

```

## Key Packages

- **treesit-auto** - Tree-sitter modes with automatic grammar installation

- **magit** - Git interface

- **magit-todos** - Show TODO/FIXME comments in magit status

### Editing

### Modes

- **markdown-mode** - Markdown editing

- **terraform-mode** - Terraform configuration files

- **exec-path-from-shell** - Import shell environment variables

- **rg** - ripgrep integration

## Key Bindings

### Custom Bindings

- `C-c c` - Compile

- `C-c r` - Recompile

- `C-c a` - Align regexp

- `C-c g` - Consult ripgrep (search with preview)

- `C-c s` - Launch eshell

- `C-x g` - Magit status

- `C-x C-b` - ibuffer (better buffer list)

- `C-=` - Expand region

- `M-p` / `M-n` - Move text up/down

- `M-%` - Visual regexp replace

- `C-M-%` - Visual regexp query replace

### Enhanced Default Bindings

- `M-x` - Command execution (enhanced with vertico)

- `C-x b` - Switch buffer (enhanced with consult)

- `M-y` - Yank from kill ring (enhanced with consult)

- `M-/` - Company completion

## Installation

1. Clone this repository:

   ```bash

   git clone [email protected]:lukehoersten/emacs.d.git ~/.emacs.d

   ```

2. Launch Emacs - packages will auto-install on first run

## Tree-sitter Support

Tree-sitter provides faster, more accurate syntax highlighting and parsing. Enabled automatically for:

- JavaScript/TypeScript

- JSON

- Python

- And many more (via `treesit-auto`)

Grammars install automatically on first use.

## Customizations

Emacs customizations are redirected to `custom.el` (gitignored) to keep `init.el` clean.

The configuration uses `package-require` for explicit package management.

## Updating Packages

```elisp

M-x package-refresh-contents

M-x package-update-all

```

## Notes

- Theme: Solarized Light (GUI only)

- Font: Inconsolata-12 (GUI only)

- Shell: eshell (launched automatically on startup)

- Whitespace cleanup on save enabled globally
