doit#

doit 的使用是一个实现细节，可能会更改！

在底层，CLI 由 doit 提供支持，它是一个用 Python 编写的轻量级任务引擎，可与 make 相媲美。

通过 API 使用任务#

隐藏代码单元格内容

 
import atexit
import os
import pathlib
import shutil
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)
print(pathlib.Path.cwd())

/tmp/_my_lite_dir_pgp771qe

LiteManager 收集来自 Addons 的所有任务，并且可以根据需要选择接受 task_prefix 以与现有任务集成。

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 IPython 魔法命令，通过扩展启用。这可以结合起来创建高度响应的构建工具，以创建非常自定义的网站。

%reload_ext doit

它针对 __main__ 命名空间工作，默认情况下不会有任何内容。

%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，当创建一个新任务时，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
