ui-forge 1.2.0

A WIP procedurally generated TUI made in NCurses using Python for CCSM

Curses UI

An easy-to-use procedurally-generated widget system for curses in Python.

item format:

item format is the main format used by the majority of widgets in this system.

definitions

An "arg," from here on out, is a key-value pair, from within a dictionary, that is itself a value of a key-value pair from within the dictionary passed to dict_ui

A sub arg is an arg that is only passed with a certain functionality

global args

These arguments will be on every item listed here, optionally unless otherwise specified.

• functionality: str required - the functionality of the item, valid values will be covered later. The program will most likely panic if this is ever not specified
• description: str - a description of the option
• always_show_description: bool - whether or not to always show the description of the item, if set to False, the description will only be shown while the item is selected.
• exit_after_action - exits the current menu after the option is selected and its functionality is performed. Can be used with the none functionality to implement an exit button.

dict_ui

Arguments:

• base_window: curses.window - a curses window
• dictionary: dict[str, dict] - a dictionary with values of dicts in item format. This is what the UI is generated from.
• item_display: Callable[[tuple[str, dict], bool], tuple[str, int]] - an optional keyword argument that allows users to overwrite the way items are listed

functionalities

• none Does nothing. Will not inhibit functionality of global args.

• run_function Runs a function with arbitrary arguments

  Sub Args:

  • function: Callable[[Unknown], None] - a reference to the function to run
  • args: list - a list of positional arguments to pass to the function
  • kwargs: dict[str, Unknown] - a dictionary of keyword arguments to pass to the function

• edit Opens the editor widget

  Sub Args:

  • value: str - the value assigned before editing - this gets overwritten after a successful edit
  • validator: Callable[[str], bool] - a reference to a function. The input is the entire submitted string, and the output will determine whether or not it will get accepted. If it does not get accepted, the input box will be reset to the previous value, and the user will be prompted to input again. This will repeat until the uset inputs a valid value.
  • allowed_human_readable: str - a string that gets printed after the name of the value the user is editing. This is intended to instruct users in an understandable fashion what values are valid or invalid.

• select Opens the selection widget

  sub args:

  • value: str - the value assigned before editing - this gets overwritten when the user selects a new value
  • options: dict[str, dict] - a dictionary containing dictionaries in item format with the option functionality

• option An option in a selection menu. Only intended to be used within the selection widget. The key is the value that will be selected.

• sub menu A new instance of dict_ui with the input menu dictionary

  Sub Args:

  • menu: dict a menu dictionary

selection_ui

Arguments:

• base_window: curses.window - a curses window
• options: dict[str, dict] - a dictionary containing dictionaries in item format with the option functionality
• item_display: Callable[[tuple[str, dict], bool], tuple[str, int]] - an optional keyword argument that allows users to overwrite the way items are listed

editor_ui

• base_window: curses.window - a curses window
• name: str - the "name" of the value being assigned, ususally analagous to the name of the variable being assigned to. This gets displayed to the user
• value: str - the default value before modification
• validator: Callable[[str], bool] - a reference to a function. The input is the entire submitted string, and the output will determine whether or not it will get accepted. If it does not get accepted, the input box will be reset to the previous value, and the user will be prompted to input again. This will repeat until the uset inputs a valid value.
• allowed_human_readable: str - a string that gets printed after the name of the value the user is editing. This is intended to instruct users in an understandable fashion what values are valid or invalid.
