使用 Ruby 在终端中捕获鼠标事件

Question

这是我一直在尝试的一些代码：

print "\e[?1003h"

begin
  loop do
    begin
      input = ARGF.read_nonblock(1024)
      puts "input: #{input.inspect}"
    rescue IO::EAGAINWaitReadable
    end
  end
ensure
  print "\e[?1003l"
end

当我运行此代码时，我可以看到类似这样的内容被打印到终端，但没有一个表明它被发送到

ARGF

。我也尝试过

STDIN

。我的

read_nonblock

调用总是引发

IO::EAGAINWaitReadable

，这似乎是预期的行为（请参阅 spec）。

如果你想自己处理，你必须在

raw

模式下捕获字符。

这应该有效：（我试图保留你的代码结构）

require 'io/console'

at_exit { print "\e[?1003l" }

print "\e[?1003h"

STDIN.raw(intr: true) do
  loop do
    begin
      input = STDIN.read_nonblock(1024)
      p input: input
    rescue IO::EAGAINWaitReadable
      IO.select([STDIN])
      retry
    end
  end
end
