Xrepo：一个现代化的跨平台 C/C++ 包管理器

xrepo 是一个基于 Xmake 的跨平台 C/C++ 包管理器。

• 项目源码
• 官方文档

它基于 xmake 提供的运行时，但却是一个完整独立的包管理程序，相比 vcpkg/homebrew 此类包管理器，xrepo 能够同时提供更多平台和架构的 C/C++ 包。

并且还支持多版本语义选择，另外它还是一个去中心化的分布式仓库，不仅仅提供了官方的 xmake-repo 仓库，还支持用户自建多个私有仓库。

同时，xrepo 也支持从 vcpkg/homebrew/conan 等第三方包管理器中安装包，并提供统一一致的库链接信息，方便与第三方项目的集成对接。

如果你想要了解更多，请参考：在线文档, Github 以及 Gitee

安装

我们只需要安装上 xmake 就可以使用 xrepo 命令，关于 xmake 的安装，我们可以看下：xmake 安装文档。

支持平台

• Windows (x86, x64)
• macOS (i386, x86_64, arm64)
• Linux (i386, x86_64, cross-toolchains ..)
• *BSD (i386, x86_64)
• Android (x86, x86_64, armeabi, armeabi-v7a, arm64-v8a)
• iOS (armv7, armv7s, arm64, i386, x86_64)
• MSYS (i386, x86_64)
• MinGW (i386, x86_64, arm, arm64)
• Cross Toolchains

支持的包管理仓库

• 官方自建仓库 xmake-repo (tbox >1.6.1)
• 用户自建仓库
• Conan (conan::openssl/1.1.1g)
• Vcpkg (vcpkg:ffmpeg)
• Homebrew/Linuxbrew (brew::pcre2/libpcre2-8)
• Pacman on archlinux/msys2 (pacman::libcurl)
• Clib (clib::clibs/bytes@0.0.4)
• Dub (dub::log 0.4.3)

分布式仓库支持

除了可以直接从官方仓库：xmake-repo 检索安装包之外，
我们还可以添加任意多个自建的仓库，甚至可以完全隔离外网，仅仅在公司内部网络维护私有包的安装集成。

只需要通过下面的命令，添加上自己的仓库地址：

$ xrepo add-repo myrepo https://github.com/mygroup/myrepo

与 xmake 的工程无缝集成

add_requires("tbox >1.6.1", "libuv master", "vcpkg::ffmpeg", "brew::pcre2/libpcre2-8")
add_requires("conan::openssl/1.1.1g", {alias = "openssl", optional = true, debug = true})
target("test")
    set_kind("binary")
    add_files("src/*.c")
    add_packages("tbox", "libuv", "vcpkg::ffmpeg", "brew::pcre2/libpcre2-8", "openssl")

下面是与 xmake 集成的整体架构和编译流程。

快速上手

安装包

基本使用

$ xrepo install zlib tbox

安装指定版本包

完整支持 Semantic Versioning (语义版本)。

$ xrepo install "zlib 1.2.x"
$ xrepo install "zlib >=1.2.0"

安装指定平台包

$ xrepo install -p iphoneos -a arm64 zlib
$ xrepo install -p android [--ndk=/xxx] zlib
$ xrepo install -p mingw [--mingw=/xxx] zlib
$ xrepo install -p cross --sdk=/xxx/arm-linux-musleabi-cross zlib

安装调试版本包

$ xrepo install -m debug zlib

安装动态库版本包

$ xrepo install -k shared zlib

安装指定配置包

$ xrepo install -f "vs_runtime=MD" zlib
$ xrepo install -f "regex=true,thread=true" boost

安装第三方包管理器的包

$ xrepo install brew::zlib
$ xrepo install vcpkg::zlib
$ xrepo install conan::zlib/1.2.11
$ xrepo install pacman:libpng
$ xrepo install dub:log

查找包的库使用信息

$ xrepo fetch pcre2
{
  {
    linkdirs = {
      "/usr/local/Cellar/pcre2/10.33/lib"
    },
    links = {
      "pcre2-8"
    },
    defines = {
      "PCRE2_CODE_UNIT_WIDTH=8"
    },
    includedirs = "/usr/local/Cellar/pcre2/10.33/include"
  }
}

$ xrepo fetch --ldflags openssl
-L/Users/ruki/.xmake/packages/o/openssl/1.1.1/d639b7d6e3244216b403b39df5101abf/lib -lcrypto -lssl

$ xrepo fetch --cflags openssl
-I/Users/ruki/.xmake/packages/o/openssl/1.1.1/d639b7d6e3244216b403b39df5101abf/include

$ xrepo fetch -p [iphoneos|android] --cflags "zlib 1.2.x"
-I/Users/ruki/.xmake/packages/z/zlib/1.2.11/df72d410e7e14391b1a4375d868a240c/include

$ xrepo fetch --cflags --ldflags conan::zlib/1.2.11
-I/Users/ruki/.conan/data/zlib/1.2.11/_/_/package/f74366f76f700cc6e991285892ad7a23c30e6d47/include -L/Users/ruki/.conan/data/zlib/1.2.11/_/_/package/f74366f76f700cc6e991285892ad7a23c30e6d47/lib -lz

导出安装后的包

xrepo 可以快速导出已经安装后的包，包括对应的库文件，头文件等等。

$ xrepo export -o /tmp/output zlib

搜索支持的包

$ xrepo search zlib "pcr*"
    zlib:
      -> zlib: A Massively Spiffy Yet Delicately Unobtrusive Compression Library (in xmake-repo)
    pcr*:
      -> pcre2: A Perl Compatible Regular Expressions Library (in xmake-repo)
      -> pcre: A Perl Compatible Regular Expressions Library (in xmake-repo)
