Cac
cac is a Node.js CLI framework used to build command line interfaces with a declarative API. It functions as a command line argument parser and a command dispatcher that maps terminal input keywords to specific JavaScript callback functions.
The framework features an automated help generator that produces usage instructions and version documentation based on the defined command structures. It manages command aliases and provides a routing system to link specific keyword inputs to execution logic.
The toolkit covers command interface definition, including the configuration of global and command-specific options. It supports argument mapping for required, optional, and variadic parameters, and includes a fallback mechanism to handle default commands when no registered keywords match.
Features
- CLI Frameworks - Provides a declarative API for defining commands and options to handle structured terminal input.
- Argument Parsing - Clack extracts flags and positional arguments from input and converts them into a structured data object.
- CLI Argument Mapping - Maps user input to specific commands using required, optional, and variadic parameters.
- Command Callbacks - Links specific keyword inputs to JavaScript callback functions that execute business logic.
- Application Command Dispatchers - Maps terminal input keywords and aliases to specific JavaScript callback functions for command execution.
- Command-Line Argument Parsers - Processes command line inputs sequentially to separate flags from positional arguments.
- Help Generators - Automatically generates terminal-friendly usage instructions and version information from defined commands.
- Help Text Generators - Automatically constructs and formats usage instructions and version documentation for terminal tools.
- Keyword-Based Command Dispatchers - Matches terminal input keywords against registered command names and aliases to trigger callback functions.
- Default Command Fallbacks - Executes a designated default action when no registered command matches the user input.
- Variadic Argument Support - Collects multiple trailing positional arguments into a single array for a specific command.
- Command Flag Configurations - Enables configuration of global and command-specific flags with default values and validation.
- Node.js CLI Tooling - Facilitates the creation of custom developer utilities and scripts with complex flag configurations and subcommands.
- Command Aliases - Assigns multiple trigger names to a single command action to support different naming conventions.
- Fluent Configuration APIs - Provides a chainable, fluent interface for defining commands and options before parsing input.
- CLI Frameworks - Framework for building CLI applications.
- Command Line Tools - Simple yet powerful framework for building command-line apps.
