## Validation Scripts
|
|
|
|
### validate-cli-structure.sh
|
|
|
|
Validates Gluegun CLI directory structure:
|
|
- Checks required files (package.json, tsconfig.json)
|
|
- Verifies directory structure (src/, src/commands/)
|
|
- Validates dependencies (gluegun)
|
|
- Checks for entry point
|
|
|
|
Usage:
|
|
```bash
|
|
./scripts/validate-cli-structure.sh <cli-directory>
|
|
```
|
|
|
|
### validate-commands.sh
|
|
|
|
Validates command files:
|
|
- Checks for required exports
|
|
- Verifies name and run properties
|
|
- Validates toolbox usage
|
|
- Checks for descriptions
|
|
|
|
Usage:
|
|
```bash
|
|
./scripts/validate-commands.sh <commands-directory>
|
|
```
|
|
|
|
### validate-templates.sh
|
|
|
|
Validates EJS template syntax:
|
|
- Checks balanced EJS tags
|
|
- Validates tag syntax
|
|
- Detects common errors
|
|
- Verifies template variables
|
|
|
|
Usage:
|
|
```bash
|
|
./scripts/validate-templates.sh <templates-directory>
|
|
```
|
|
|
|
### test-cli-build.sh
|
|
|
|
Tests CLI build process:
|
|
- Validates dependencies
|
|
- Runs TypeScript compilation
|
|
- Tests CLI execution
|
|
- Runs test suites
|
|
|
|
Usage:
|
|
```bash
|
|
./scripts/test-cli-build.sh <cli-directory>
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Basic CLI
|
|
|
|
Simple CLI demonstrating core patterns:
|
|
- Command structure
|
|
- Parameter handling
|
|
- Template generation
|
|
- Print utilities
|
|
|
|
See: `examples/basic-cli/`
|
|
|
|
### Plugin System
|
|
|
|
Extensible CLI with plugin architecture:
|
|
- Plugin discovery
|
|
- Plugin loading
|
|
- Custom extensions
|
|
- Plugin commands
|
|
|
|
See: `examples/plugin-system/`
|
|
|
|
### Template Generator
|
|
|
|
Advanced template patterns:
|
|
- Multi-file generation
|
|
- Conditional templates
|
|
- Template composition
|
|
- Helper functions
|
|
|
|
See: `examples/template-generator/`
|
|
|
|
## Usage
|
|
|
|
### In Agent Context
|
|
|
|
When building CLI tools, agents will automatically discover this skill based on keywords:
|
|
- "CLI tool"
|
|
- "command structure"
|
|
- "template system"
|
|
- "Gluegun"
|
|
- "plugin architecture"
|
|
|
|
### Direct Reference
|
|
|
|
Load templates:
|
|
```bash
|
|
Read: /path/to/skills/gluegun-patterns/templates/commands/basic-command.ts.ejs
|
|
```
|
|
|
|
Use validation:
|
|
```bash
|
|
Bash: /path/to/skills/gluegun-patterns/scripts/validate-cli-structure.sh ./my-cli
|
|
```
|
|
|
|
## Best Practices
|
|
|
|
1. **Command Organization**
|
|
- One command per file
|
|
- Clear naming conventions
|
|
- Descriptive help text
|
|
|
|
2. **Template Design**
|
|
- Keep templates simple
|
|
- Use helper functions for logic
|
|
- Document variables
|
|
|
|
3. **Error Handling**
|
|
- Validate user input
|
|
- Check API responses
|
|
- Provide helpful messages
|
|
|
|
4. **Plugin Architecture**
|
|
- Use unique namespaces
|
|
- Document plugin APIs
|
|
- Handle missing dependencies
|
|
|
|
5. **Testing**
|
|
- Test commands in isolation
|
|
- Validate template output
|
|
- Mock external dependencies
|
|
|
|
## Security
|
|
|
|
- Never hardcode API keys (use environment variables)
|
|
- Validate all user input
|
|
- Sanitize file paths
|
|
- Check permissions before file operations
|
|
- Use placeholders in templates (e.g., `your_api_key_here`)
|
|
|
|
