Command Autocomplete System

Build a command line tool that helps users discover and execute commands through an interactive autocomplete interface.

Requirements

Create a Python script that provides an interactive command selection interface with autocomplete functionality. The system should help users find and execute commands from a predefined list.

Command Database

The tool should support these commands:

• list files - Lists all files in the current directory
• list directories - Lists all directories in the current directory
• search files - Searches for files by name pattern
• show help - Displays help information
• clear screen - Clears the terminal screen
• print date - Prints the current date
• print time - Prints the current time
• exit program - Exits the tool

Functionality

1. Interactive Selection: Present an interactive prompt asking "Select a command to execute:"

2. Autocomplete Behavior:

   • Users should be able to type partial command text
   • The system should show matching suggestions as the user types
   • Matching should work for partial strings (e.g., typing "file" should match both "list files" and "search files")
   • Matching should be case-insensitive

3. Command Execution: After selection, the tool should:

   • Print a message: "You selected: [command name]"
   • Print the command description
   • Not actually execute the command (just display what was selected)

4. Program Flow: After displaying the selection, the program should exit normally

Implementation Details

@generates

Create a single Python script that implements this functionality. The script should be executable from the command line.

API

def get_command_choices():
    """
    Returns a list of command strings available for selection.

    Returns:
        list: A list of command name strings
    """
    pass

def get_command_description(command):
    """
    Returns the description for a given command.

    Args:
        command (str): The command name

    Returns:
        str: The command description
    """
    pass

def main():
    """
    Main entry point that presents the interactive command selector
    and handles the user's selection.
    """
    pass

Test Cases

• When the user types "list" and selects "list files", the output should contain "You selected: list files" followed by "Lists all files in the current directory" @test

• When the user types "time" and selects "print time", the output should contain "You selected: print time" followed by "Prints the current time" @test

• The autocomplete should match "files" to both "list files" and "search files" (case-insensitive partial matching) @test
