input-plus 0.2.1

A Python package.

Input-Plus

Input-Plus is a Python library that provides advanced input handling functions. It extends the built-in input function with additional features such as date/time input, float and integer input, password input with masking, and more.

Base Input Function

The input_plus.input() function allows for more advanced input handling than the built-in input function. All other functions in this library are built on top of this function.

It takes four functions as arguments:

• printer: A function that renders visual feedback to the user. Default prints with no formatting.
• selector: A function that runs when the input is submitted. Default always returns True and the input string.
• validator: A function that validates each character as it is typed. Default is None and does not validate.
• special_actions: A function that takes user input string as bytes and performs a special action based on the input. Default is None and does nothing.

Function Arguments Signature

printer

Arguments:

• str: This is the string that the user has typed so far. Returns:
• str | None: If non-None is returned, the input string will be replaced with the returned string.

selector

Arguments:

• str: This is the final string that the user has typed. Returns:
• A tuple containing a boolean indicating if the input is valid and the final input string.
  • bool: Indicates if the input is valid. If not true, the input will be blocked and user will keep control.
  • str: The final input string.

validator

Arguments:

• str: This is the string that the user has typed so far. Returns:
• bool: If not true, the character will be blocked. (Not added/removed from the input string)

special_actions

Arguments:

• bytes: The special key input. Returns:
• None

Note: the selector boolean and the validator boolean are used differently. The selector boolean is used to determine if the final input is valid, while the validator boolean is used to determine if each character is valid. If the selector boolean is False, the input will be blocked and the user will keep control. If the validator boolean is False, the character will be blocked (act as if it was never typed).

Input Functions

input_plus.regex()

This function allows for input validation using a regular expression.

Arguments:

• prompt: The prompt to display to the user.
• regex: The regular expression to validate the input.
• force_match: If True, the input will be ignored if it does not match the regex. Default is False. Will block mid-input if the input does not match the regex. Do not use if the input has to be typed completely before it is valid. for example, a phone number input with '\d{3}-\d{3}-\d{4}' will block the first input since it does not match the regex. you would have to use 'd{0,10}' to allow the user to type the input.
• warn_error: If True, the input will be displayed in red if it does not match the regex. Default is True.
• placeholder: String to show as a gray text to show the expected format. Default is None.

Sub-Functions

These functions use the input_plus.regex() function with a pre-defined regular expression.

input_plus.integer()

This function allows for integer input.

Arguments:

• prompt: The prompt to display to the user.

input_plus.float()

This function allows for float input.

Arguments:

• prompt: The prompt to display to the user.

input_plus.email()

This function allows for email input.

Arguments:

• prompt: The prompt to display to the user.

input_plus.phone()

This function allows for phone number input.

Arguments:

• prompt: The prompt to display to the user.

input_plus.url()

This function allows for URL input.

Arguments:

• prompt: The prompt to display to the user.

input_plus.hex()

This function allows for hexadecimal input.

Arguments:

• prompt: The prompt to display to the user.

input_plus.select()

This function allows for selecting an option from a list of options.

Arguments:

• prompt: The prompt to display before the input.
• options: A list of options to select from. Can be a list of strings or a list of dictionaries with the keys 'Option' and 'Description'.
  • input_plus.option(): A function that creates an option dictionary.
• list_size: The number of options to display at once. Default is 5.
• fixed_order: If True, the options will be displayed in the order they are provided and can not be searched. Default is False.

Sub-Functions input_plus.option()

This function creates an option dictionary.

Arguments:

• option: The option to display to the user.
• description: The description of the option.

input_plus.date()

This function allows for date input.

Arguments:

• prompt: The prompt to display to the user.
• type: The type of input to get from the user. (date, time, datetime) Default is datetime.
• default_datetime: The default date and time to display to the user. Default is the current date and time.
• hours: The hour format to use. (12, 24) Default is 24.
• step_with_enter: If True, the user will have to press enter to move to the next field. Default is False.

input_plus.password()

This function allows for password input with masking.

Arguments:

• prompt: The prompt to display to the user.
• mask: The character to display instead of the input. Default is ''. No character will be displayed.
• hash_function: The function to hash the password with. Default is SHA-256.

input_plus.func()

This function allows for inputting a function's parameters and returns the result of the function.

Arguments:

• prompt: The prompt to display to the user.
• func: The function to handle the input.
• sig_check: Restricts how vague the funcion's signature can be.
  • strict: All parameters must have a type hint.
