# CherryPick CLI
A command-line tool for managing and generating `build.yaml` configuration for the [CherryPick](https://github.com/pese-git/cherrypick) dependency injection ecosystem for Dart & Flutter.
---
## Features
- 📦 Quickly add or update CherryPick generator sections in your project's `build.yaml`.
- 🛡️ Safely preserves unrelated configs and packages.
- 📝 Always outputs a human-friendly, formatted YAML file.
- 🏷️ Supports custom output directories and custom build.yaml file paths.
---
## Getting Started
1. **Navigate to the CLI package directory:**
```bash
cd cherrypick_cli
```
2. **Get dependencies:**
```bash
dart pub get
```
3. **Run the CLI:**
```bash
dart run cherrypick_cli init --output_dir=lib/generated
```
---
## Usage
### Show help
```bash
dart run cherrypick_cli --help
```
### Add or update CherryPick sections in build.yaml
```bash
dart run cherrypick_cli init --output_dir=lib/generated
```
#### Options:
- `--output_dir`, `-o` — Directory for generated code (default: `lib/generated`)
- `--build_yaml`, `-f` — Path to build.yaml file (default: `build.yaml`)
#### Example with custom build.yaml
```bash
dart run cherrypick_cli init --output_dir=custom/dir --build_yaml=custom_build.yaml
```
---
## What does it do?
- Adds or updates the following sections in your `build.yaml` (or custom file):
- `cherrypick_generator|inject_generator`
- `cherrypick_generator|module_generator`
- Ensures all YAML is pretty-printed and readable.
- Leaves unrelated configs untouched.
---
## Example Output
```yaml
targets:
$default:
builders:
cherrypick_generator|inject_generator:
options:
build_extensions:
^lib/{{}}.dart:
- lib/generated/{{}}.inject.cherrypick.g.dart
output_dir: lib/generated
generate_for:
- lib/**.dart
cherrypick_generator|module_generator:
options:
build_extensions:
^lib/di/{{}}.dart:
- lib/generated/di/{{}}.module.cherrypick.g.dart
output_dir: lib/generated
generate_for:
- lib/**.dart
```
