prestringがasync/awaitをサポートした
prestringがasync/awaitをサポートした。
（そしてしれっとmypyで型をつけた（実はこちらのほうが大変だった））
prestring?
prestringは文字列を生成するためのライブラリ。with構文を乱用している。
例えば以下の様なコードが
00main.py
from prestring.python import Module m = Module() with m.def_("main"): m.stmt("print('hello world')") with m.if_("__name__ == '__main__'"): m.stmt("main()") print(m)
以下の様なコードを出力する。
def main():
print('hello world')
if __name__ == '__main__':
main()
なのでプロセス置換を使って実行してあげれば"hello world"を出力する。
$ python <(python 00main.py) hello world
prestring.transform
自分の手で書くのがめんどうなら python -m prestring.python にソースコードを渡してあげると、そのコードを生成するコードを出力してくれる。
例えば以下の様なコードを渡してみる。
01fizzbuzz.py
def fizzbuzz(n: int) -> str: if n % 3 == 0 and n % 5 == 0: return "fizzbuzz" elif n % 3 == 0: return "fizz" elif n % 5 == 0: return "buzz" else: return str(n) if __name__ == "__main__": print(", ".join(fizzbuzz(i) for i in range(1, 21)))
このコードを生成するコードを出力してくれる。
$ python -m prestring.python 01fizzbuzz.py
from prestring.python import PythonModule
def gen(*, m=None, indent=' '):
m = m or PythonModule(indent=indent)
with m.def_('fizzbuzz', 'n: int', return_type='str'):
with m.if_('n % 3 == 0 and n % 5 == 0'):
m.stmt('return "fizzbuzz"')
with m.elif_('n % 3 == 0'):
m.stmt('return "fizz"')
with m.elif_('n % 5 == 0'):
m.stmt('return "buzz"')
with m.else_():
m.stmt('return str(n)')
with m.if_('__name__ == "__main__"'):
m.stmt('print(", ".join(fizzbuzz(i) for i in range(1, 21)))')
return m
if __name__ == "__main__":
m = gen(indent=' ')
print(m)
もちろんこのコードが出力したコードを実行すれば元のコードのように振る舞う。
$ python <(python <(python -m prestring.python 01fizzbuzz.py)) 1, 2, fizz, 4, buzz, fizz, 7, 8, fizz, buzz, 11, fizz, 13, 14, fizzbuzz, 16, 17, fizz, 19, buzz
async/await 対応
ここからがようやく本題。そんなprestringだけれど。今まではasync/awaitの構文をサポートしていなかった。
これを今回サポートしたという話。例えば以下の様なコードを書く。オプションとして async_=True を付けるとasync defやasync forなどとして扱われる。
例えば、pythonのドキュメントのfutureの部分のコードは以下の様な形で書ける。
from prestring.python import PythonModule as Module m = Module() m.import_("asyncio") m.stmt("# from: https://docs.python.org/ja/3/library/asyncio-future.html") m.sep() with m.def_("set_after", "fut", "delay", "value", async_=True): m.stmt("# Sleep for *delay* seconds.") m.stmt("await asyncio.sleep(delay)") m.stmt("# Set *value* as a result of *fut* Future.") m.stmt("fut.set_result(value)") with m.def_("main", async_=True): m.stmt("# Get the current event loop.") m.stmt("loop = asyncio.get_running_loop()") m.stmt("# Create a new Future object.") m.stmt("fut = loop.create_future()") m.stmt('# Run "set_after()" coroutine in a parallel Task.') m.stmt('# We are using the low-level "loop.create_task()" API here because') m.stmt("# we already have a reference to the event loop at hand.") m.stmt('# Otherwise we could have just used "asyncio.create_task()".') m.stmt('loop.create_task(set_after(fut, 1, "... world"))') m.stmt('print("hello ...")') m.stmt("# Wait until *fut* has a result (1 second) and print it.") m.stmt("print(await fut)") m.stmt("asyncio.run(main())") print(m)
実行結果
$ python 02asyncio-future.py
import asyncio
# from: https://docs.python.org/ja/3/library/asyncio-future.html
async def set_after(fut, delay, value):
# Sleep for *delay* seconds.
await asyncio.sleep(delay)
# Set *value* as a result of *fut* Future.
fut.set_result(value)
async def main():
# Get the current event loop.
loop = asyncio.get_running_loop()
# Create a new Future object.
fut = loop.create_future()
# Run "set_after()" coroutine in a parallel Task.
# We are using the low-level "loop.create_task()" API here because
# we already have a reference to the event loop at hand.
# Otherwise we could have just used "asyncio.create_task()".
loop.create_task(set_after(fut, 1, "... world"))
print("hello ...")
# Wait until *fut* has a result (1 second) and print it.
print(await fut)
asyncio.run(main())
async for, async with
もちろんasync for, async withにも対応している。そして先程の python -m prestring.python も完全に手書きしたものと同じにはならないがasync/awaitが使われているコードも対応している。
例えばこういうトリビアルなコードがあったときに
aexecutor.py
import typing as t import asyncio from functools import partial class AExecutor: def __init__(self): self.q = asyncio.Queue() async def __aenter__(self) -> t.Callable[..., t.Awaitable[None]]: async def loop(): while True: afn = await self.q.get() if afn is None: self.q.task_done() break await afn() self.q.task_done() asyncio.ensure_future(loop()) return self.q.put async def __aexit__( self, exc: t.Optional[t.Type[BaseException]], value: t.Optional[BaseException], tb: t.Any, ): await self.q.put(None) await self.q.join() async def arange(n: int) -> t.AsyncIterator[int]: for i in range(n): yield i await asyncio.sleep(0.1) async def run(): async with AExecutor() as submit: async def task(tag: str): async for i in arange(3): print(tag, i) await submit(partial(task, "x")) await submit(partial(task, "y")) def main(): asyncio.run(run()) if __name__ == "__main__": main()
python -m prestring.python は以下の様なコードを生成する。
$ python -m prestring.python aexecutor.py
from prestring.python import PythonModule
def gen(*, m=None, indent=' '):
m = m or PythonModule(indent=indent)
m.import_('typing as t')
m.import_('asyncio')
m.from_('functools', 'partial')
with m.class_('AExecutor'):
with m.def_('__init__', 'self'):
m.stmt('self.q = asyncio.Queue()')
with m.def_('__aenter__', 'self', return_type='t.Callable[..., t.Awaitable[None]]', async_=True):
with m.def_('loop', async_=True):
with m.while_('True'):
m.stmt('afn = await self.q.get()')
with m.if_('afn is None'):
m.stmt('self.q.task_done()')
m.stmt('break')
m.stmt('await afn()')
m.stmt('self.q.task_done()')
m.stmt('asyncio.ensure_future(loop())')
m.stmt('return self.q.put')
with m.def_('__aexit__', 'self', 'exc: t.Optional[t.Type[BaseException]]', 'value: t.Optional[BaseException]', 'tb: t.Any', async_=True):
m.stmt('await self.q.put(None)')
m.stmt('await self.q.join()')
with m.def_('arange', 'n: int', return_type='t.AsyncIterator[int]', async_=True):
with m.for_('i in range(n)'):
m.stmt('yield i')
m.stmt('await asyncio.sleep(0.1)')
with m.def_('run', async_=True):
with m.with_('AExecutor() as submit', async_=True):
with m.def_('task', 'tag: str', async_=True):
with m.for_('i in arange(3)', async_=True):
m.stmt('print(tag, i)')
m.stmt('await submit(partial(task, "x"))')
m.stmt('await submit(partial(task, "y"))')
with m.def_('main'):
m.stmt('asyncio.run(run())')
with m.if_('__name__ == "__main__"'):
m.stmt('main()')
return m
if __name__ == "__main__":
m = gen(indent=' ')
print(m)
もちろん出力結果は正しいpythonコードなので実行もできる。
$ python <(python <(python -m prestring.python aexecutor.py)) x 0 x 1 x 2 y 0 y 1 y 2
おまけ prestring.python.parse
ついでに python -m prestring.python のコードを書いていてlib2to3用のASTを確認するのがめんどうだったので python -m prestring.python.parse でASTをdumpする機能もつけてみた。
$ python -m prestring.python.parse aexecutor.py
