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.
With pip, for the latest stable:
$ pip install cursed
Or from the project root directory:
$ python setup.py install
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()
Many more examples are available in the root of the repository at examples/
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.
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
added tons of documentation and examples
Better CursedMenu API
WIDTH or HEIGHT specified as ‘max’ will stretch to the full width or height of the terminal
patched issue with returning bytes in getstr
Fixed menu to fill up right side with whitespace
fixed menus stealing keypresses
left and right open menus to sides
