Swift Macro 不使用 Swift Package Manager如何集成

• Swift Macro分为两部分,一部分为宏的具体实现(编译器插件),一部分为Macro Lib用于导出宏定义以及所需要的附属代码,这里说的不使用SPM指的是编译器插件这部分
• 仔细观察Xcode使用SPM集成Macro时，在编译命令中通过-load-plugin-executable参数指定了对应宏实现的插件可执行文件路径
• 同时在swift源码中也找到了相关参数TypeCheckMacros.cpp TypeCheckMacros.cpp
• 从swift源码中可得知，宏实现插件即可以是动态库(dylib)也可以是可执行文件
• 系统内置的宏实现是通过 -plugin-path <dylib path> 加载
• 内置的宏实现动态库在Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/Lib/swift/host/plugins

具体步骤

• 编写宏实现代码,这一步可以通过SPM也可以直接通过Xcode创建命令行程序项目,完成宏实现代码编写

glv

# This sets up fish so that, if you type a command that should be
# run using Bundler, it first automatically prepends "bundle exec"
# to the command line buffer before executing it. Works for all
# commands found in the "bin" directory of the current bundle.
#
# To override this behavior and run such a command without Bundler,
# prefix with "command" (e.g., `command rake -T`)
#
# Pros (vs binstubs or aliases):
# * automatically adjusts to bundle changes
