nuio 0.0.4

功能

目前，nuio能够与posix终端进行eal。 对应的类在nuio.input.terminal和nio.output.terminal中。

哲学

Nuio试图让事情尽可能简单， 但它需要python3.5.1+语言特性。

任何阻塞的用户输入都是使用异步特性完成的，这是 将来会很方便的。

计划

应添加以下功能：

• 基于诅咒的I/O
• 基于ajax的i/o系统
• 非POSIX终端
• blockoutput的花式框架

示例

这是nuio的一个简单示例：

#!/usr/bin/python3

from nuio.input.terminal import POSIXTerminalInput
from nuio.output.terminal import TerminalOutput, ESCAPES, TerminalBlockOutput
import asyncio, shutil


async def main():
        width, height = shutil.get_terminal_size()

        # an output device
        out = TerminalBlockOutput(height - 10, width)
        out.print("This is a test")

        # input devices require an output device to handle prompts.
        inp = POSIXTerminalInput(out)

        data = await inp.input_int(prompt = "enter an integer > ")

        # You are able to use a bunch of ANSI escape sequences.
        # Usually you should use nuio.output.terminal.colors instead,
        # this will be compatible with other output devices.

        out.print_colored(ESCAPES["underline"], "you entered:", data)

        data = await inp.input_int(prompt = "enter an integer [4-100] > ",
                        range = range(4, 100))
        out.print_colored(ESCAPES["fg_red"], "you entered:", data)

        data = await inp.input_float(prompt = "enter an float [4-100] > ",
                        range = range(4, 100))
        out.print_colored(ESCAPES["bg_cyan"] + ESCAPES["fg_black"], "you entered:", data)



# Usually you should make the input async,
# but to simplify this the complete main function is async.
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()
