## Introduction

xrepo is a cross-platform C/C++ package manager based on Xmake.

It is based on the runtime provided by xmake, but it is a complete and independent package management program. Compared with package managers such as vcpkg/homebrew, xrepo can provide C/C++ packages for more platforms and architectures at the same time.

And it also supports multi-version semantic selection. In addition, it is also a decentralized distributed repository. It not only provides the official xmake-repo repository, It also supports users to build multiple private repositorys.

At the same time, xrepo also supports installing packages from third-party package managers such as vcpkg/homebrew/conan, and provides unified and consistent library link information to facilitate integration and docking with third-party projects.

If you want to know more, please refer to: Documents, Github and Gitee

## Installation

We only need install xmake to use the xrepo command. About the installation of xmake, we can see: Xmake Installation Document.

## Supported platforms

- 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

## Suppory distributed repository

In addition to directly retrieving the installation package from the official repository: xmake-repo.

We can also add any number of self-built repositories, and even completely isolate the external network, and only maintain the installation and integration of private packages on the company's internal network.

Just use the following command to add your own repository address:

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

## Seamless integration with xmake project

    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")

The following is the overall architecture and compilation process integrated with xmake.

## Get started

### Use it in cmake

We need CMake wrapper for Xrepo C and C++ package manager. xrepo-cmake

### Installation package

#### Basic usage

    $ xrepo install zlib tbox

#### Install the specified version package

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

#### Install the specified platform package

    $ 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

#### Install the debug package

    $ xrepo install -m debug zlib

#### Install the package with dynamic library

    $ xrepo install -k shared zlib

#### Install the specified configuration package

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

#### Install packages from third-party package manager

    $ xrepo install brew::zlib
    $ xrepo install vcpkg::zlib
    $ xrepo install conan::zlib/1.2.11

### Find the library information of the package

    $ 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

### Import and export packages

xrepo can quickly export the installed packages, including the corresponding library files, header files, and so on.

    $ xrepo export -o /tmp/output zlib

You can also import the previously exported installation package on other machines to implement package migration.

    $ xrepo import -i /xxx/packagedir zlib

### Search supported packages

    $ 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)

In addition, you can now search for their packages from third-party package managers such as vcpkg, conan, conda, and apt. You only need to add the corresponding package namespace, for example:

    $ xrepo search vcpkg::pcre
    The package names:
         vcpkg::pcre:
           -> vcpkg::pcre-8.44#8: Perl Compatible Regular Expressions
           -> vcpkg::pcre2-10.35#2: PCRE2 is a re-working of the original Perl Compatible Regular Expressions library

    $ xrepo search conan::openssl
    The package names:
         conan::openssl:
           -> conan::openssl/1.1.1g:
           -> conan::openssl/1.1.1h:

### Show package environment information

    $ xrepo env --show luajit
    {
       OLDPWD = "/mnt/tbox",
       HOME = "/home/ruki",
       PATH = "/home/ruki/.xmake/packages/l/luajit/2.1.0-beta3/fbac76d823b844f0b91abf3df0a3bc61/bin:/tmp:/tmp/arm-linux-musleabi-cross/bin:~/.local/bin: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",
       TERM = "xterm",
       PWD = "/mnt/xmake",
       XMAKE_PROGRAM_DIR = "/mnt/xmake/xmake",
       HOSTNAME = "e6edd61ff1ab",
       LD_LIBRARY_PATH = "/home/ruki/.xmake/packages/l/luajit/2.1.0-beta3/fbac76d823b844f0b91abf3df0a3bc61/lib",
       SHLVL = "1",
       _ = "/mnt/xmake/scripts/xrepo.sh"
    }

### Load package environment and run commands

    $ xrepo env luajit
    LuaJIT 2.1.0-beta3 -- Copyright (C) 2005-2017 Mike Pall. http://luajit.org/
    JIT: ON SSE2 SSE3 SSE4.1 BMI2 fold cse dce fwd dse narrow loop abc sink fuse
    >

    $ xrepo env -b "luajit 2.x" luajit
    $ xrepo env -p iphoneos -b "zlib,libpng,luajit 2.x" cmake ..

### Enter the package shell environment

We can customize some package configurations by adding the xmake.lua file in the current directory, and then enter the specific package shell environment.

    add_requires("zlib 1.2.11")
    add_requires("python 3.x", "luajit")

    $ xrepo env shell
    > python --version
    > luajit --version

We can also configure and load the corresponding toolchain environment in xmake.lua, for example, load the VS compilation environment.

    set_toolchains("msvc")

### Show the given package information

    $ xrepo info zlib
    The package info of project:
        require(zlib):
          -> description: A Massively Spiffy Yet Delicately Unobtrusive Compression Library

             -> vs_runtime: Set vs compiler runtime. (default: MT)
                -> values: {"MT","MD"}

### Uninstall all packages

We can use the following command to batch uninstall and delete the installed packages, supporting pattern matching:

    $ xrepo remove --all
    $ xrepo remove --all zlib pcr*
