示例1: getchar
# 需要導入模塊: import msvcrt [as 別名]
# 或者: from msvcrt import getwche [as 別名]
def getchar(echo):
# The function `getch` will return a bytes object corresponding to
# the pressed character. Since Windows 10 build 1803, it will also
# return \x00 when called a second time after pressing a regular key.
#
# `getwch` does not share this probably-bugged behavior. Moreover, it
# returns a Unicode object by default, which is what we want.
#
# Either of these functions will return \x00 or \xe0 to indicate
# a special key, and you need to call the same function again to get
# the "rest" of the code. The fun part is that \u00e0 is
# "latin small letter a with grave", so if you type that on a French
# keyboard, you _also_ get a \xe0.
# E.g., consider the Up arrow. This returns \xe0 and then \x48. The
# resulting Unicode string reads as "a with grave" + "capital H".
# This is indistinguishable from when the user actually types
# "a with grave" and then "capital H".
#
# When \xe0 is returned, we assume it's part of a special-key sequence
# and call `getwch` again, but that means that when the user types
# the \u00e0 character, `getchar` doesn't return until a second
# character is typed.
# The alternative is returning immediately, but that would mess up
# cross-platform handling of arrow keys and others that start with
# \xe0. Another option is using `getch`, but then we can't reliably
# read non-ASCII characters, because return values of `getch` are
# limited to the current 8-bit codepage.
#
# Anyway, Click doesn't claim to do this Right(tm), and using `getwch`
# is doing the right thing in more situations than with `getch`.
