doit

使用 doit 是一个实现细节，可能会发生变化！

在幕后，CLI 由 doit 提供支持，这是一个轻量级的 Python 任务引擎，类似于 make。

import atexit
import os

import tempfile

from IPython.display import *

if "TMP_DIR" not in globals():
    TMP_DIR = pathlib.Path(tempfile.mkdtemp(prefix="_my_lite_dir_"))

    def clean():
        shutil.rmtree(TMP_DIR)

    atexit.register(clean)
os.chdir(TMP_DIR)

LiteManager 从附加组件中收集所有任务，并且可以选择接受一个 task_prefix，以防您需要与现有任务集成。

from jupyterlite_core.manager import LiteManager

manager = LiteManager(task_prefix="lite_")
manager.initialize()
manager.doit_run("lite_status")

自定义任务和 %doit

doit 提供了一个 IPython 魔法，通过扩展启用。这可以结合起来为创建非常自定义的网站创建高度反应式构建工具。

%reload_ext doit

它针对 __main__ 命名空间工作，默认情况下该命名空间将没有任何内容。

%doit list

所有 JupyterLite 任务都可以通过 globals 更新 __main__ 来添加。

globals().update(manager._doit_tasks)

现在，当创建新任务时，它可以引用其他任务和目标。

def task_hello():
    return dict(actions=[lambda: print("HELLO!")], task_dep=["lite_post_status"])

%doit -v2 hello
