setuptools 对于现代python包支持的简单试用

以前我们编写python包通过setuptools 是编写配置setup.cfg以及一个setup.py 文件，现代的玩法是基于pyproject.toml
以下是一个简单学习

项目准备

使用venv

• cli

python -m venv venv

source venv/bin/activate

• 创建项目文件
  pyproject.toml，里边包含了build backend

[build-system]

requires = ["setuptools"]

build-backend = "setuptools.build_meta"

setup.cfg 主要是配置一些信息，当然也都可以写到pyproject.toml 中

[metadata]

name = dalong

version = 0.0.1

description = a package  for learning

 

[options]

 

[options.packages.find]

where = src

include = dalong.*

 

[options.entry_points]

sqlalchemy.dialects =

    dalong=dalong.app:app

• 构建

python -m build

• 效果

说明

以上是一个简单的试用，setuptools 也在持续演进，值得重新学习下
