Includes subparsers for nested commands, choices for validation, custom actions, argument groups, and mutually exclusive options. + +## Instructions + +### Basic Parser Setup + +1. Import argparse and create parser with description +2. Add version info with `action='version'` +3. Set formatter_class for better help formatting +4. Parse arguments with `parser.parse_args()` + +### Subparsers (Nested Commands) + +1. Use `parser.add_subparsers(dest='command')` to create command groups +2. Add individual commands with `subparsers.add_parser('command-name')` +3. Each subparser can have its own arguments and options +4. Nest subparsers for multi-level commands (e.g., `mycli config get key`) + +### Choices and Validation + +1. Use `choices=['opt1', 'opt2']` to restrict values +2. Implement custom validation with type functions +3. Add validators using argparse types +4. Set defaults with `default=value` + +### Actions + +1. `store_true/store_false` - Boolean flags +2. `store_const` - Store constant value +3. `append` - Collect multiple values +4. `count` - Count flag occurrences +5. `version` - Display version and exit +6. Custom actions with Action subclass + +### Argument Types + +1. Positional arguments - Required by default +2. Optional arguments - Prefix with `--` or `-` +3. Type coercion - `type=int`, `type=float`, `type=pathlib.Path` +4. Nargs - `'?'` (optional), `'*'` (zero or more), `'+'` (one or more) + +## Available Templates + +### Python Templates + +- **basic-parser.py** - Simple parser with arguments and options +- **subparser-pattern.py** -

Use `help=` for every argument +2. **Set sensible defaults** - Use `default=` to avoid None values +3. **Use choices for fixed options** - Better than manual validation +4. **Group related arguments** - Use `add_argument_group()` for clarity +5. **Handle missing subcommands** - Check if `args.command` is None +6. **Use type coercion** - Prefer `type=int` over manual conversion +7. **Provide examples** - Use `epilog=` for usage examples + +## Advantages Over External Libraries + +- **No dependencies** - Built into Python standard library +- **Stable API** - Won't break with updates +- **Universal** -

Use when building CLI tools, creating commands with flags, implementing subcommands, adding before/after hooks, organizing command categories, or when user mentions Go CLI, urfave/cli, cobra alternatives, CLI flags, CLI categories. +allowed-tools: Bash, Read, Write, Edit +--- + +# CLI Patterns Skill + +Lightweight Go CLI patterns using urfave/cli for fast, simple command-line applications. + +## Overview + +Provides battle-tested patterns for building production-ready CLI tools in Go using urfave/cli v2. Focus on simplicity, speed, and maintainability over complex frameworks like Cobra. + +## Why urfave/cli? + +- **Lightweight**: Minimal dependencies, small binary size +- **Fast**: Quick compilation, fast execution +- **Simple API**: Easy to learn, less boilerplate than Cobra +- **Production-ready**: Used by Docker, Nomad, and many other tools +- **Native Go**: Feels like standard library code + +## Core Patterns + +### 1. Basic CLI Structure + +Use `templates/basic-cli.go` for simple single-command CLIs: +- Main command with flags +- Help text generation +- Error handling +- Exit codes + +### 2. Subcommands + +Use `templates/subcommands-cli.go` for multi-command CLIs: +- Command hierarchy (app → command → subcommand) +- Shared flags across commands +- Command aliases +- Command categories + +### 3. Flags and Options + +Use `templates/flags-demo.go` for comprehensive flag examples: +- String, int, bool, duration flags +- Required vs optional flags +- Default values +- Environment variable fallbacks +- Flag aliases (short and long forms) +- Custom flag types + +### 4. Command Categories + +Use `templates/categories-cli.go` for organized command groups: +- Group related commands +- Better help text organization +- Professional CLI UX +- Examples: database commands, deploy commands, etc. + +### 5. Before/After Hooks + +Use `templates/hooks-cli.go` for lifecycle management: +- Global setup (before all commands) +- Global cleanup (after all commands) +- Per-command setup/teardown +- Initialization and validation +- Resource management + +### 6. Context and State + +Use `templates/context-cli.go` for shared state: +- Pass configuration between commands +- Share database connections +- Manage API clients +- Context values + +## Scripts + +### Generation Scripts + +**`scripts/generate-basic.sh `** +- Generates basic CLI structure +- Creates main.go with single command +- Adds common flags (verbose, config) +- Includes help text template + +**`scripts/generate-subcommands.sh `** +- Generates multi-command CLI +- Creates command structure +- Adds subcommand examples +- Includes command categories + +**`scripts/generate-full.sh `** +- Generates complete CLI with all patterns +- Includes before/after hooks +- Adds comprehensive flag examples +- Sets up command categories +- Includes context management + +### Utility Scripts + +**`scripts/add-command.sh `** +- Adds new command to existing CLI +- Updates command registration +- Creates command file +- Adds to appropriate category + +**`scripts/add-flag.sh `** +- Adds flag to command +- Supports all flag types +- Includes environment variable fallback +- Adds help text + +**`scripts/validate-cli.sh `** +- Validates CLI structure +- Checks for common mistakes +- Verifies flag definitions +- Ensures help text exists + +## Templates + +### Core Templates + +**`templates/basic-cli.go`** +- Single-command CLI +- Standard flags (verbose, version) +- Error handling patterns +- Exit code management + +**`templates/subcommands-cli.go`** +- Multi-command structure +- Command registration +- Shared flags +- Help text organization + +**`templates/flags-demo.go`** +- All flag types demonstrated +- Environment variable fallbacks +- Required flag validation +- Custom flag types + +**`templates/categories-cli.go`** +- Command categorization +- Professional help output +- Grouped commands +- Category-based organization + +**`templates/hooks-cli.go`** +- Before/After hooks +- Global setup/teardown +- Per-command hooks +- Resource initialization + +**`templates/context-cli.go`** +- Context management +- Shared state +- Configuration passing +- API client sharing + +### TypeScript Equivalent (Node.js) + +**`templates/commander-basic.ts`** +- commander.js equivalent patterns +- TypeScript type safety +- Similar API to urfave/cli + +**`templates/oclif-basic.ts`** +- oclif framework patterns (Heroku/Salesforce style) +- Class-based commands +- Plugin system + +### Python Equivalent + +**`templates/click-basic.py`** +- click framework patterns +- Decorator-based commands +- Python CLI best practices + +**`templates/typer-basic.py`** +- typer framework (FastAPI CLI) +- Type hints for validation +- Modern Python patterns + +## Examples + +### Example 1: Database CLI Tool + +**`examples/db-cli/`** +- Complete database management CLI +- Commands: connect, migrate, seed, backup +- Categories: schema, data, admin +- Before hook: validate connection +- After hook: close connections + +### Example 2: Deployment Tool + +**`examples/deploy-cli/`** +- Deployment automation CLI +- Commands: build, test, deploy, rollback +- Categories: build, deploy, monitor +- Context: share deployment config +- Hooks: setup AWS credentials + +### Example 3: API Client + +**`examples/api-cli/`** +- REST API client CLI +- Commands: get, post, put, delete +- Global flags: auth token, base URL +- Before hook: authenticate +- Context: share HTTP client + +### Example 4: File Processor + +**`examples/file-cli/`** +- File processing tool +- Commands: convert, validate, optimize +- Categories: input, output, processing +- Flags: input format, output format +- Progress indicators + +## Best Practices + +### CLI Design + +1. **Keep it simple**: Start with basic structure, add complexity as needed +2. **Consistent naming**: Use kebab-case for commands (deploy-app, not deployApp) +3. **Clear help text**: Every command and flag needs description +4. **Exit codes**: Use standard codes (0=success, 1=error, 2=usage error) + +### Flag Patterns + +1. **Environment variables**: Always provide env var fallback for important flags +2. **Sensible defaults**: Required flags should be rare +3. **Short and long forms**: -v/--verbose, -c/--config +4. **Validation**: Validate flags in Before hook, not in action + +### Command Organization + +1. **Categories**: Group related commands (>5 commands = use categories) +2. **Aliases**: Provide shortcuts for common commands +3. **Subcommands**: Use for hierarchical operations (db migrate up/down) +4. **Help text**: Keep concise, provide examples + +### Performance + +1. **Fast compilation**: urfave/cli compiles faster than Cobra +2. **Small binaries**: Minimal dependencies = smaller output +3. **Startup time**: Use Before hooks for expensive initialization +4. **Lazy loading**: Don't initialize resources unless command needs them + +## Common Patterns + +### Configuration File Loading + +```go +app.Before = func(c *cli.Context) error { + configPath := c.String("config") + if configPath != "" { + return loadConfig(configPath) + } + return nil +} +``` + +### Environment Variable Fallbacks + +```go +&cli.StringFlag{ + Name: "token", + Aliases: []string{"t"}, + Usage: "API token", + EnvVars: []string{"API_TOKEN"}, +} +``` + +### Required Flags + +```go +&cli.StringFlag{ + Name: "host", + Required: true, + Usage: "Database host", +} +``` + +### Global State Management + +```go +type AppContext struct { + Config *Config + DB *sql.DB +} + +app.Before = func(c *cli.Context) error { + ctx := &AppContext{ + Config: loadConfig(), + } + c.App.Metadata["ctx"] = ctx + return nil +} +``` + +## Validation + +Run `scripts/validate-cli.sh` to check: +- All commands have descriptions +- All flags have usage text +- Before/After hooks are properly defined +- Help text is clear and concise +- No unused imports +- Proper error handling + +## Migration Guides + +### From Cobra to urfave/cli + +See `examples/cobra-migration/` for: +-

+**Testing Strategy:** +- Always test both success (0) and failure (non-zero) cases +- Verify specific exit codes for different error conditions +- Test argument validation returns appropriate codes

Choose CLI Structure Pattern + +Select the appropriate CLI structure based on your use case: + +- **simple**: Single command with flags (quick utilities) +- **flat**: Root command with subcommands at one level +- **nested**: Hierarchical command structure (kubectl-style) +- **plugin**: Extensible CLI with plugin support +- **hybrid**: Mix of built-in and dynamic commands + +### 2. Generate Cobra CLI Structure + +Use the setup script to scaffold a new Cobra CLI: + +```bash +cd /home/gotime2022/.claude/plugins/repos/cli-builder/skills/cobra-patterns +./scripts/setup-cobra-cli.sh +``` + +**Structure types:** `simple`, `flat`, `nested`, `plugin`, `hybrid` + +**Example:** +```bash +./scripts/setup-cobra-cli.sh myctl nested +``` + +**What This Creates:** +- Complete directory structure with cmd/ package +- Root command with initialization +- Example subcommands +- Flag definitions (local and persistent) +- Cobra initialization (cobra init pattern) +- Go module configuration +- Main entry point + +### 3. Command Structure Patterns + +#### Basic Command Structure + +```go +var exampleCmd = &cobra.Command{ + Use: "example [flags]", + Short: "Brief description", + Long: `Detailed description with examples`, + Args: cobra.ExactArgs(1), + Run: func(cmd *cobra.Command, args []string) { + // Command logic + }, +} +``` + +#### Command with Lifecycle Hooks + +```go +var advancedCmd = &cobra.Command{ + Use: "advanced", + Short: "Advanced command with hooks", + PersistentPreRun: func(cmd *cobra.Command, args []string) { + // Runs before command execution (inherited by children) + }, + PreRun: func(cmd *cobra.Command, args []string) { + // Runs before command execution (local only) + }, + Run: func(cmd *cobra.Command, args []string) { + // Main command logic + }, + PostRun: func(cmd *cobra.Command, args []string) { + // Runs after command execution (local only) + }, + PersistentPostRun: func(cmd *cobra.Command, args []string) { + // Runs after command execution (inherited by children) + }, +} +``` + +#### Command with Error Handling + +```go +var robustCmd = &cobra.Command{ + Use: "robust", + Short: "Command with proper error handling", + RunE: func(cmd *cobra.Command, args []string) error { + // Return errors instead of os.Exit + if err := validateInput(args); err != nil { + return fmt.Errorf("validation failed: %w", err) + } + + if err := executeOperation(); err != nil { + return fmt.Errorf("operation failed: %w", err) + } + + return nil + }, +} +``` + +### 4.

Multiple Return Types and Output Formatting + +Fire handles different return types automatically: + +```python +import fire +from rich.console import Console +from rich.table import Table +import json + +console = Console() + +class MyCLI: + """CLI with rich output formatting""" + + def status(self): + """Show application status (returns dict)""" + return { + "status": "running", + "version": "1.0.0", + "uptime": "24h", + "active_users": 42 + } + + def list_items(self): + """List items with table formatting (returns list)""" + items = [ + {"id": 1, "name": "Item A", "status": "active"}, + {"id": 2, "name": "Item B", "status": "pending"}, + {"id": 3, "name": "Item C", "status": "completed"} + ] + + table = Table(title="Items") + table.add_column("ID", style="cyan") + table.add_column("Name", style="magenta") + table.add_column("Status", style="green") + + for item in items: + table.add_row(str(item['id']), item['name'], item['status']) + + console.print(table) + return items + + def export(self, format='json'): + """Export data in specified format + + Args: + format: Output format - json, yaml, or text (default: json) + """ + data = {"items": [1, 2, 3], "total": 3} + + if format == 'json': + return json.dumps(data, indent=2) + elif format == 'yaml': + return f"items:\n - 1\n - 2\n - 3\ntotal: 3" + else: + return f"Total items: {data['total']}" + +if __name__ == '__main__': + fire.Fire(MyCLI) +``` + +### 4.

mycli.py version # Access property directly +python mycli.py debug # Access property directly +python mycli.py info # Call method +``` + +## Available Templates + +Use the following templates for generating Fire CLI applications: + +- **basic-fire-cli.py.template** - Simple single-class Fire CLI +- **nested-fire-cli.py.template** - Multi-class CLI with command groups +- **rich-fire-cli.py.template** - Fire CLI with rich console output +- **typed-fire-cli.py.template** - Type-annotated Fire CLI +- **config-fire-cli.py.template** - Fire CLI with configuration management +- **multi-command-fire-cli.py.template** - Complex multi-command Fire CLI + +## Available Scripts + +- **generate-fire-cli.sh** - Generate Fire CLI from specification +- **validate-fire-cli.py** - Validate Fire CLI structure and docstrings +- **extract-commands.py** - Extract command structure from Fire CLI +- **test-fire-cli.py** - Test Fire CLI commands programmatically + +## Key Fire CLI Principles + +### Automatic Command Generation + +Fire automatically generates CLI commands from: +- Public methods (commands) +- Method parameters (command arguments and flags) +- Docstrings (help text and argument descriptions) +- Nested classes (command groups) +- Properties (read-only values) + +### Docstring Parsing + +Fire parses docstrings to generate help text: + +```python +def command(self, arg1, arg2='default'): + """Command description shown in help + + Args: + arg1: Description of arg1 (shown in help) + arg2: Description of arg2 (shown in help) + + Returns: + Description of return value + """ + pass +``` + +### Boolean Flags + +Fire converts boolean parameters to flags: + +```python +def deploy(self, force=False, verbose=False): + """Deploy with optional flags""" + pass + +# Usage: +# python cli.py deploy --force --verbose +# python cli.py deploy --noforce # Explicitly set to False +``` + +### Default Values + +Default parameter values become default flag values: + +```python +def init(self, template='basic', port=8000): + """Initialize with defaults""" + pass + +# Usage: +# python cli.py init # Uses defaults +# python cli.py init --template=react # Override template +# python cli.py init --port=3000 # Override port +``` + +## Integration with Rich Console + +Enhance Fire CLIs with rich formatting: + +```python +from rich.console import Console +from rich.progress import track +from rich.panel import Panel +import fire +import time + +console = Console() + +class MyCLI: + """Rich-enhanced Fire CLI""" + + def process(self, items=100): + """Process items with progress bar + + Args: + items: Number of items to process + """ + console.print(Panel("[bold green]Processing

'__main__': + fire.Fire(MyCLI) +``` + +## Best Practices + +1. **Clear Docstrings**: Write comprehensive docstrings for auto-generated help +2. **Nested Classes**: Use nested classes for logical command grouping +3. **Default Values**: Provide sensible defaults for all optional parameters +4. **Type Hints**: Use type annotations for better IDE support +5. **Return Values**: Return data structures that Fire can serialize +6. **Rich Output**: Use rich console for enhanced terminal output +7. **Validation**: Validate inputs within methods, not in Fire setup +8. **Error Handling**: Use try-except blocks and return error messages + +## Common Patterns + +### Confirmation Prompts + +```python +def delete(self, resource, confirm=False): + """Delete resource with confirmation + + Args: + resource: Resource to delete + confirm: Skip confirmation prompt + """ + if not confirm: + console.print("[yellow]Use --confirm to delete[/yellow]") + return + + console.print(f"[red]Deleting

console.print("[dim]Verbose mode enabled[/dim]") +``` + +## Requirements + +- Python 3.7+ +- google-fire package: `pip install fire` +- rich package (optional): `pip install rich` +- Type hints

+## Best Practices Summary + +1. **Error Handling**: Always validate inputs and handle errors gracefully +2. **Confirmation**: Require confirmation for destructive operations +3. **Dry Run**: Implement dry-run mode for risky operations +4. **Logging**: Log important actions to file for audit trail +5. **Type Hints**: Use type hints for better IDE support +6. **Properties**: Use properties

Commands go in `src/commands/` directory + - Each command exports a `GluegunCommand` object + - Use templates from `templates/` directory + - Reference template: `templates/commands/basic-command.ts.ejs` + +3. **Implement command with toolbox:** + ```typescript + module.exports = { + name: 'generate', + run: async (toolbox) => { + const { template, print, parameters } = toolbox + const name = parameters.first + + await template.generate({ + template: 'model.ts.ejs', + target: `src/models/${name}.ts`, + props: { name } + }) + + print.success(`Generated ${name} model`) + } + } + ``` + +### Template System + +1. **Template file structure:** + - Store templates in `templates/` directory + - Use EJS syntax: `<%= variable %>`, `<%- unescaped %>` + - Reference: `templates/toolbox/template-examples.ejs` + +2. **Generate files from templates:** + ```typescript + await template.generate({ + template: 'component.tsx.ejs', + target: `src/components/${name}.tsx`, + props: { name, style: 'functional' } + }) + ``` + +3. **Helper functions:** + - `props.camelCase` - camelCase conversion + - `props.pascalCase` - PascalCase conversion + - `props.kebabCase` - kebab-case conversion + - Reference: `scripts/template-helpers.ts` + +### Filesystem Operations + +1. **Common operations (fs-jetpack):** + ```typescript + // Read/write files + const config = await filesystem.read('config.json', 'json') + await filesystem.write('output.txt', data) + + // Directory operations + await filesystem.dir('src/components') + const files = filesystem.find('src', { matching: '*.ts' }) + + // Copy/move/remove + await filesystem.copy('template', 'output') + await filesystem.move('old.txt', 'new.txt') + await filesystem.remove('temp') + ``` + +2. **Path utilities:** + ```typescript + filesystem.path('src', 'commands') // Join paths + filesystem.cwd() // Current directory + filesystem.separator // OS-specific separator + ``` + +### HTTP Utilities + +1. **API interactions:** + ```typescript + const api = http.create({ + baseURL: 'https://api.example.com', + headers: { 'Authorization': 'Bearer token' } + }) + + const response = await api.get('/users') + const result = await api.post('/users', { name: 'John' }) + ``` + +2. **Error handling:** + ```typescript + if (!response.ok) { + print.error(response.problem) + return + } + ``` + +### Interactive Prompts + +1. **User input patterns:** + ```typescript + // Ask question + const result = await prompt.ask({ + type: 'input', + name: 'name', + message: 'What is your name?' + }) + + // Confirm action + const proceed = await prompt.confirm('Continue?') + + // Select from list + const choice = await prompt.ask({ + type: 'select', + name: 'framework', + message: 'Choose framework:', + choices: ['React', 'Vue', 'Angular'] + }) + ``` + +2. **Multi-select and complex forms:** + - Reference: `examples/prompts/multi-select.ts` + - See: `templates/toolbox/prompt-examples.ts.ejs` + +### Plugin Architecture + +1. **Create extensible plugins:** + ```typescript + // Plugin structure + export default (toolbox) => { + const { filesystem, template } = toolbox + + // Add custom extension + toolbox.myFeature = { + doSomething: () => { /* ... */ } + } + } + ``` + +2. **Load plugins:** + ```typescript + cli.plugins('./node_modules', { matching: 'mycli-*' }) + cli.plugins('./plugins', { matching: '*.js' }) + ``` + +3. **Plugin examples:** + - Reference: `examples/plugin-system/custom-plugin.ts` + - See: `templates/plugins/plugin-template.ts.ejs` + +### Print Utilities + +1. **Colorful output:** + ```typescript + print.info('Information message') + print.success('Success message') + print.warning('Warning message') + print.error('Error message') + print.highlight('Highlighted text') + print.muted('Muted text') + ``` + +2. **Spinners and progress:** + ```typescript + const spinner = print.spin('Loading...') + await doWork() + spinner.succeed('Done!') + + // Or fail + spinner.fail('Something went wrong') + ``` + +3. **Tables and formatting:** + ```typescript + print.table([ + ['Name', 'Age'], + ['John', '30'], + ['Jane', '25'] + ]) + ``` + +### System Commands + +1. **Execute external commands:** + ```typescript + const output = await system.run('npm install') + const result = await system.exec('git status') + + // Spawn with options + await system.spawn('npm run build', { stdio: 'inherit' }) + ``` + +2. **Check command availability:** + ```typescript + const hasGit = await system.which('git') + ``` + +### File Patching + +1. **Modify existing files:** + ```typescript + // Add line after pattern + await patching.update('package.json', (content) => { + const pkg = JSON.parse(content) + pkg.scripts.build = 'tsc' + return JSON.stringify(pkg, null, 2) + }) + + // Insert import statement + await patching.insert('src/index.ts', 'import { Router } from "express"') + ``` + +## Validation Scripts + +Use these scripts to validate Gluegun CLI implementations: + +- `scripts/validate-cli-structure.sh` -

support +2. **Prefer Enums over strings**: For constrained choices +3. **Use Path for file paths**: Better validation than str +4. **Document with docstrings**: Typer uses them for help text +5. **Keep commands focused**: One command = one responsibility +6. **Use sub-apps for grouping**: Organize related commands together +7. **Test with factory pattern**: Makes CLIs unit-testable + +##
