A fast project switcher and worktree manager for git.

## Install

### From source

```bash
cargo install git-yawn
```

### Nix flake

```nix
inputs.yawn.url = "github:ComeBertrand/yawn";

# then in your packages:
inputs.yawn.packages.${system}.default
```

### GitHub Releases

Download a binary from the [releases page](https://github.com/ComeBertrand/yawn/releases), or use the shell installer:

```bash
curl --proto '=https' --tlsv1.2 -LsSf https://github.com/ComeBertrand/yawn/releases/latest/download/yawn-installer.sh | sh
```

## Usage

```
yawn list [path] [--json] [--raw] [--porcelain]  Discover git projects
yawn resolve <pretty-name> [-P <path>]  Map a pretty name back to an absolute path
yawn pick [-F <finder>] [path]  Interactively pick a project and open it
yawn open <path> [-c <command>] Open a terminal in the given directory
yawn create <name> [--source <base>] [--open] [--init]  Create a git worktree
yawn delete <name>              Remove a worktree
yawn init                       Initialize the current directory
```

### Listing projects

Recursively discovers git projects under a directory. Takes an optional path, defaults to the current directory.

```bash
yawn list ~/projects           # pretty output (tree in terminal, flat when piped)
yawn list                      # discover projects under cwd
yawn list --porcelain          # force flat pretty names (stable for scripts)
yawn list --raw                # absolute paths, one per line
yawn list --json               # structured JSON output
```

By default, the output is human-friendly. In a terminal, projects are shown as a colored tree with worktrees grouped under their parent:

```
my-app
├─ fix-branch
└─ feature-x
dotfiles
notes (personal)
notes (work)
```

When piped (or with `--porcelain`), it falls back to flat pretty names for compatibility with tools like `fzf`:

```
my-app
fix-branch @my-app
feature-x @my-app
dotfiles
notes (personal)
notes (work)
```

The `--raw` flag outputs absolute paths, one per line:

```
/home/user/projects/my-app
/home/user/worktrees/my-app--fix-branch
/home/user/worktrees/my-app--feature-x
/home/user/projects/dotfiles
```

The `--json` flag outputs an array of objects with `path`, `name`, `is_worktree`, and `worktree_of` fields:

```bash
yawn list ~/projects --json
# [
#   { "path": "/home/user/projects/myapp", "name": "myapp", "is_worktree": false, "worktree_of": null },
#   { "path": "/home/user/projects/myapp--feature", "name": "feature @myapp", "is_worktree": true, "worktree_of": "myapp" }
# ]
```

If run inside a git repo (without a path), it lists the repo itself and its worktrees:

```bash
cd ~/projects/my-app
yawn list
```

```
/home/user/projects/my-app
/home/user/worktrees/my-app--fix-branch
/home/user/worktrees/my-app--feature-x
```

### Interactive project switcher

Use `yawn pick` with any fuzzy finder:

```bash
# fzf
yawn pick -F fzf ~/projects

# rofi
yawn pick -F "rofi -dmenu -p project -i" ~

# from current directory
yawn pick -F fzf
```

This discovers projects, pipes pretty names into the finder, resolves the selection, and opens a terminal — all in one command. Easy to bind in i3/sway/hyprland.

The equivalent manual pipeline still works:

```bash
yawn open "$(yawn resolve -P ~ "$(yawn list ~ --pretty | fzf)")"

# override the configured open command for a single invocation
yawn open /path/to/project -c "code {dir}"
```

### Worktrees

Worktrees are created under a configurable root directory (default: `~/worktrees`) using the naming convention `<project>--<name>`. For example, running `yawn create feature-x` from inside a repo called `my-app` creates:

```
~/worktrees/my-app--feature-x
```

When listing with `--pretty`, the `<project>--` prefix is stripped and the worktree is annotated:

```
feature-x @my-app
```

Branch resolution when creating a worktree follows this order:

1. If `<name>` exists as a local branch, check it out.
2. If `<name>` exists as `origin/<name>`, track it.
3. If `--source <base>` is provided, create a new branch from `<base>`.
4. Otherwise, create a new branch from the default branch (`origin/HEAD`, falling back to `main` then `master`).

```bash
# Create a worktree (new branch from default branch)
yawn create feature-x

# Create from a specific base branch
yawn create feature-x --source develop

# Create and immediately open a terminal in it
yawn create feature-x --open

# Create and run init (copy files + setup commands)
yawn create feature-x --init

# All flags combine
yawn create feature-x --source develop --init --open

# Delete a worktree
yawn delete feature-x
```

### Initializing a project

`yawn init` sets up the current directory by copying files from the main repo and running setup commands. Configuration lives in `.yawn.toml` at the repo root:

```toml
[init]
include = [".env", ".env.local", "config/*.toml"]
commands = ["npm install", "cargo build"]
```

- **`include`** — files, directories, and glob patterns to copy from the main repo into worktrees. Directories are copied recursively. Useful for local config files (`.env`, etc.) that aren't tracked by git.
- **`commands`** — shell commands to run sequentially in the target directory. Stops on first failure.

When run in a worktree, `yawn init` copies include files from the main repo and then runs commands. When run in the main repo itself (e.g. after a fresh clone), it skips the copy step and only runs commands.

```bash
# Initialize the current directory
yawn init

# Create a worktree and initialize it in one step
yawn create feature-x --init
```

## Configuration

There are two config files:

- **`~/.config/yawn/config.toml`** — global user config (discovery, session, worktree settings)
- **`.yawn.toml`** — per-project config, lives in the repo root and should be committed to git (init settings)

### `.yawn.toml` (per-project)

| Key | Type | Description |
|---|---|---|
| `init.include` | list of strings | Files, directories, or glob patterns to copy from the main repo into worktrees. Directories are copied recursively. |
| `init.commands` | list of strings | Shell commands to run sequentially during init. |

```toml
[init]
include = [".env", ".env.local", "config/*.toml"]
commands = ["npm install"]
```

### `~/.config/yawn/config.toml` (global)

All fields are optional.

### `[discovery]`

| Key | Type | Default | Description |
|---|---|---|---|
| `max_depth` | integer | `5` | Maximum recursion depth when searching for git projects. |
| `ignore` | list of strings | `[".*", "node_modules"]` | Glob patterns matched against directory names. Matching directories are skipped during discovery. Hidden directories (except `.git` itself) are ignored by default. |

### `[session]`

| Key | Type | Default | Description |
|---|---|---|---|
| `opener` | string | unset | Command template to open a terminal session. Placeholders: `{dir}` (absolute path), `{name}` (directory basename). When unset, uses `$TERMINAL`, or falls back to `Terminal.app` on macOS and `xterm` on Linux. |
| `finder` | string | unset | Default finder command for `yawn pick` (e.g. `fzf`, `rofi -dmenu -p project -i`). Can be overridden with `-F`. |

### `[worktree]`

| Key | Type | Default | Description |
|---|---|---|---|
| `root` | string | `~/worktrees` | Directory where worktrees are created. Supports `~` expansion. |
| `auto_init` | boolean | `false` | Automatically run init after creating a worktree (equivalent to always passing `--init`). |

### Example

```toml
[discovery]
max_depth = 3
ignore = [".*", "node_modules", "target", "vendor"]

[session]
opener = "kitty --directory {dir} --title 'dev: {name}'"
finder = "fzf"

[worktree]
root = "~/worktrees"
```

## Shell Completion

### Bash

```bash
cp completions/yawn.bash ~/.local/share/bash-completion/completions/yawn
```

### Zsh

```bash
cp completions/yawn.zsh ~/.local/share/zsh/site-functions/_yawn
```

Or place it anywhere in your `$fpath`.

### Fish

```bash
cp completions/yawn.fish ~/.config/fish/completions/yawn.fish
```
