Perl + Curses: Expecting a UTF-8 encoded multibyte character from getchar(), but not getting any

问题 I am trying out Bryan Henderson's Perl interface to the ncurses library: Curses For a simple exercise, I try to obtain single characters typed on-screen. This is directly based off the NCURSES Programming HOWTO, with adaptations. When I call the Perl library's getchar() , I expect to receive a character, possibly multibyte (It's a bit more complicated as explained in this part of the library manpage because one has to handle the special cases of function keys and no input, but that's just the

Which $TERM to use to have both 256 colors and mouse move events in python curses?

问题 Currently if I set the TERM environment variable to 'xterm-1003' I can get mouse move events but I get crappy colors and curses.can_change_color() == False os.environ['TERM'] = 'xterm-1003' ... curses.mousemask(curses.ALL_MOUSE_EVENTS | curses.REPORT_MOUSE_POSITION) ... while True: event = screen.getch() if event == curses.KEY_MOUSE: # I get nice events whenever I move the mouse (no click required) _, mx, my, _, _ = curses.getmouse() and if I set the TERM env var to 'xterm-256color' I get a

How does ncurses output non-ascii characters?

由 故事扮演 提交于 2020-03-26 09:49:10
问题 I'd like to know how ncurses (a c library) manages to put characters like ├ , despite them not (to the best of my knowledge) being part of ASCII. I would have assumed it was just drawing them pixel by pixel, but you can copy/paste them out of the terminal (in MacOS). 回答1: ncurses puts characters such as ├ on the screen by assuming that your locale environment variables ( LC_ALL and/or LC_CTYPE ) match the terminal on which you are displaying. The environment variables indicate the encoding (e
