### Install herdr-spreader as a herdr plugin

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/README.md

Installs the plugin by cloning the repository, running `cargo build --release`, and registering it with herdr.

```bash
herdr plugin install yuk1ty/herdr-spreader
```

--------------------------------

### Create plugin config directory

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/README.md

Creates the plugin's config directory and prints its path. Place your layout file named `config.yaml` or `config.yml` in that directory.

```bash
herdr plugin config-dir herdr-spreader
# => ~/.config/herdr/plugins/config/herdr-spreader
```

--------------------------------

### Build, test, and iterate on the herdr-spreader plugin

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/README.md

Run the standard Rust development checks (build, test, clippy with warnings denied, and formatting) and then link the plugin to a local herdr instance and invoke the herdr-spreader.apply action for iterative testing.

```bash
cargo build
cargo test
cargo clippy --all-targets -- -D warnings
cargo fmt

# Iterate on the plugin against a real herdr instance
herdr plugin link ./
herdr plugin action invoke herdr-spreader.apply
```

--------------------------------

### herdr-spreader apply usage

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/README.md

Usage syntax for the apply command. The `--file` flag specifies a layout YAML file; if omitted, the plugin searches predefined config directories.

```bash
herdr-spreader apply [--file <path>]
```

--------------------------------

### Apply herdr workspace layout with herdr-spreader apply

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/README.md

Applies the workspace layout defined in the YAML file, reproducing the configured workspaces, tabs, and panes. The command is run from the project root.

```shell
$ herdr-spreader apply
```

--------------------------------

### Invoke herdr-spreader apply action

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/README.md

Runs the layout from within any herdr workspace. Alternatively, trigger it from herdr's action menu (`Apply layout`).

```bash
herdr plugin action invoke herdr-spreader.apply
```

--------------------------------

### Define herdr workspace layout in YAML

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/README.md

Defines two workspaces (frontend and backend) with tabs, panes, environment variables, and focus settings. The backend workspace is marked focus: true, and the editor pane in the backend has focus: true. The cargo watch pane uses wait_for with match "Compiling" and timeout_ms 10000.

```yaml
workspaces:
  - name: frontend
    root: ~/code/my-project/frontend
    env:
      NODE_ENV: development
    tabs:
      - label: editor
        cwd: ./src
        panes:
          - command: nvim
          - split: down
            ratio: 0.3
            command: npm run dev
  - name: backend
    root: ~/code/my-project/backend
    focus: true
    env:
      RUST_LOG: debug
    tabs:
      - label: editor
        cwd: ./src
        panes:
          - command: nvim
            focus: true
          - split: down
            ratio: 0.3
            command: cargo watch -x test
            wait_for:
              match: "Compiling"
              timeout_ms: 10000
      - label: server
        panes:
          - command: cargo run
```

--------------------------------

### Build and run standalone CLI

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/README.md

Builds and runs herdr-spreader as a standalone CLI. Works outside a herdr session as long as a herdr server is running and the `herdr` binary is on `PATH`.

```bash
cargo build --release
./target/release/herdr-spreader apply --file ./config.yaml

# or
cargo install --path .
```

--------------------------------

### Shell prefix for first pane cwd/env override

Source: https://github.com/yuk1ty/herdr-spreader/blob/main/ARCHITECTURE.md

Used when a first pane needs a cwd or env beyond its workspace/tab baseline. Prefixed to the pane's run command; quoted with shell_quote (POSIX single-quote escaping). If the pane has no command but needs cwd/env, this line alone is run.

```shell
cd '<resolved dir>' && export KEY='value' && <the user's command>
```
