Simplified curses interface with concurrency, for quick and sane curses apps.

Allows easy creation of windows and menus. Code for each window runs concurrently.

Please see full documentation available here: http://pythonhosted.org/cursed/

cursed was tested with Python 3.4 and 2.7, and depends on the Python package six for compatibility.

Installation

With pip, for the latest stable:

$ pip install cursed

Or from the project root directory:

$ python setup.py install

Usage

Example:

from cursed import CursedApp, CursedWindow

# the main context of the curses application
app = CursedApp()

# Derive from CursedWindow to declare curses windows to be created after app.run()
# It is required to declare X, Y, WIDTH, and HEIGHT for each window.
# You'll want to put the main looping code for each window thread in the `update` class function.

class MainWindow(CursedWindow):

    # Coordinate for top-left of window.
    X, Y = (0, 0)

    # WIDTH and HEIGHT can be 'max' or integers.
    WIDTH, HEIGHT = ('max', 'max')

    # Create a default border around the window.
    BORDERED = True

    @classmethod
    def update(cls):
        ''' update runs every tick '''

        # Hello world printed at x,y of 0,0
        cls.addstr('Hello, world!', 0, 0)

        # Get character keycode of keypress, or None.
        if cls.getch() == 27:
            # Escape was pressed. Quit.
            # 'quit' must be triggered for each open window for the program to quit.
            # Call cls.trigger('quit') to quit the window you're in, and to quit the other
            # declared windows, call OtherWindow.trigger('quit') which will run in that
            # window's thread, regardless of where it's called.
            cls.trigger('quit')

# To trigger app to start
result = app.run()

# check if ctrl-C was pressed
if result.interrupted():
    print('Quit!')
else:
    # Raises an exception if any thread ran into a different exception.
    result.unwrap()

Release Notes

0.2.0:

• exposed gevent.sleep through a classmethod cls.sleep(seconds=0). This allows users to fix issues with long running update functions causing other windows to not respond.

• Added a CursedWindow PAD, like the curses pad. This can have a huge width and height greater than the terminal width, but allow you to scroll around it. Useful for windows which need only display a smaller rectange of a larger window, like a map that scrolls around with arrow keys.

0.1.9:

• fixed the write and getstr classmethods, since they called _fix_xy twice

• added info to menu example to explain addstr in update will overwrite menu display

0.1.8:

• added tons of documentation and examples

0.1.7:

• Better CursedMenu API

0.1.6:

• WIDTH or HEIGHT specified as ‘max’ will stretch to the full width or height of the terminal

0.1.5:

• patched issue with returning bytes in getstr

0.1.4:

• Implemented getstr

0.1.3:

• Fixed menu to fill up right side with whitespace

0.1.2:

• fixed menus stealing keypresses

0.1.1:

• refactored menus

0.1.0:

• implemented menus!

0.0.2:

• implemented lots from the following:
