How can I print messages based on all option values after config stage?

autoconf/cmake/meson常见在所有config结束之后打印一系列信息：

xmake如何实现？在option:after_check()里面似乎无法保证其余所有option都已经check完毕

[waruqi]

xmake f -v 可以看到启用的 options

[xq114]

这个文档里没找到，是怎么个用法呢

[waruqi]

这个文档里没找到，是怎么个用法呢

跟 before_build 用法一样，只不过执行阶段在 xmake config 完成后

前几个版本加的 目前还在内部验证中 所以还没加到文档公开

不过目前测下来 还可以 如果没啥大问题，后面就定下来了

[waruqi]

用法可以到源码 rules 里面搜下 有例子

[xq114]

这个地方用target:on_config也行吗

[waruqi]

可以
