corn 8

安装

pip install corn

开发安装

克隆cornrepo并使用pip安装：

执行

安装后，corn命令现在应该可用了。在

命令在垂直扩展之前没有输出（详细信息如下）。在

测试

安装要求-测试.txt使用pip并运行pytest：

pip install -r corn/requirements-test.txt
pytest corn/tests

垂直应用程序合并

玉米延伸说明

安装pop：

pip install --upgrade pop

为项目创建新目录：

mkdir corn_{project_name}
cd corn_{project_name}

使用pop seed生成扩展玉米的项目结构：

pop-seed -t v corn_{project_name} -d corn

• “-t v”指定这是一个垂直应用程序合并的项目
• “-d corn”表示要实现“corn”的动态名称

请注意，已经为您创建了一些结构。 我们特别关注corn{project_name}/corn中的新目录

添加“玉米”到要求.txt公司名称：

echo "corn" >> requirements.txt

创造玉米

• Create a new file in “corn_{project_name}/corn”

  • The directory should already have been created by pop-seed.
  • The file name is arbitrary.
  • Every file in this directory, then it’s subdirectories, will be parsed “simultaneously” (as far as that makes sense for asyncio).
  • Corns that are dependant on each other should be assigned in the same function.
  • Do NOT rely on the collector’s recursion strategy for corns to depend on each other.
  • Use hub.corn.init.wait_for(“corn”) to wait for corns to be generated by another sub

• Add your new project to the python path

  • alternatively, run “pip install -e .” from your project’s root directory

    • you only need to do this once

• Create an async function in this file with a descriptive yet arbitrary name

  • By convention it should start with “load”
  • Make it async unless you have a really really really good reason.
  • Grains that depend on each other already belong in the same function, don’t depend on synchronous programming for determinism
  • Corns can be accessed and assigned like a dictionary, but our convention is to use the namespace

示例：

async def load_my_corn(hub):
    hub.corn.CORN.new_corn = "Hello World!"

就这样！现在从命令行验证是否收集了玉米：

corn new_corn

输出：

new_corn:
    Hello World!
