描述问题

after_build_file 不能 hook proto 文件，直接跳过了。

期待的结果

希望能 hook proto 文件，这样便自己去生成 proto 对应的 python 文件

工程配置

set_project("test")
set_languages("c++20")

set_version("1.0.0", {build = "%Y%m%d"})

add_requires("protobuf-cpp", {system = false})

target("demo")
    set_kind("binary")
    add_files("src/main.cc")
    add_files("src/demo.proto")
    add_rules("protobuf.cpp")
    add_packages("protobuf-cpp")
    add_packages("grpc")

    before_build_file(function (target, sourcefile, opt)
        print("before ====>", sourcefile, opt)
    end)

    after_build_file(function (target, sourcefile, opt)
        print("after ---->", sourcefile, opt)  -- 只打印了 main.cc，没有 demo.proto
    end)

Title: after_build_file cannot hook proto file

[waruqi]

target 的 after_build_file 只拦截已知的 cpp files，.proto 是 protobuf.cpp 的 rule 里面拦截处理的，它不属于内置的源文件。。你要 hook 也得走 rule ，然后通过 set_extensions 针对性 hook

xmake/xmake/rules/protobuf/xmake.lua

set_extensions(".proto")

The after_build_file of the target only intercepts known cpp files, and .proto is intercepted and processed in the rule of protobuf.cpp. . If you want to hook, you have to follow the rule, and then use set_extensions to target the hook
