-# repo
+### 大致流程
+ **注意:**  以下说明中包含{*}的内容均代表变量
+1. manifest.xml 文件配置
+2. repo 引导命令下载
+3. repo init 初始化
+4. repo sync 仓库同步
+5. repo start {BRANCH} [project1, project2]进行批量分支切换开始开发......
+6. repo stage/repo forall -c git add . 或是 自行提交
+7. repo config repo.token {ACCESS_TOKEN} 配置gitee个人API token
+8. repo config repo.pullrequest {True/Fales} 配置是否开启push后，向指定分支进行的PR提交的特性
+9. repo push -p --br={BRANCH} --d={DEST_BRANCH} --new_branch 用本地的指定分支向远程推送并关联，推送成功后向指定的分支进批量提交
+10. repo sync 或 repo forall -c git pull 进行代码批量同步

-Repo is a tool built on top of Git.  Repo helps manage many Git repositories,
-does the uploads to revision control systems, and automates parts of the
-development workflow.  Repo is not meant to replace Git, only to make it
-easier to work with Git.  The repo command is an executable Python script
-that you can put anywhere in your path.

-## Contact
-
-Please use the [repo-discuss] mailing list or [issue tracker] for questions.
-
-You can [file a new bug report][new-bug] under the "repo" component.
-
-Please do not e-mail individual developers for support.
-They do not have the bandwidth for it, and often times questions have already
-been asked on [repo-discuss] or bugs posted to the [issue tracker].
-So please search those sites first.
-
-## Install
-
-Many distros include repo, so you might be able to install from there.
-```sh
-# Debian/Ubuntu.
-$ sudo apt-get install repo
-
-# Gentoo.
-$ sudo emerge dev-vcs/repo
+### manifest配置例子
+在名为**manifest**的仓库中创建一个default.xml文件作为repo初始化的依据  
+以下为repo init初始化命令, 需要用 **-u**参数  来指定manifest的git仓库
+```shell
+repo init -u git@gitee.com:{namespace}/manifest.git
 ```
+**default.xml文件用例**
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<manifest>
+  <remote  name="gitee"
+           fetch="git@gitee.com:{namespace}"     
+           autodotgit="true" /> <!--fetch=".." 代表使用 repo init -u 指定的相对路径 也可用完整路径，example:https://gitee.com/MarineJ/manifest_example/blob/master/default.xml-->
+  <default revision="master"
+           remote="gitee" /><!--revision为默认的拉取分支，后续提pr也以revision为默认目标分支-->
 
-You can install it manually as well as it's a single script.
-```sh
-$ mkdir -p ~/.bin
-$ PATH="${HOME}/.bin:${PATH}"
-$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
-$ chmod a+rx ~/.bin/repo
+  <project path="repo_test1" name="repo_test1" />  <!--git@gitee.com:{namespace}/{name}.git  name项与clone的url相关-->
+  <project path="repo_test2" name="repo_test2" /> 
+
+</manifest>
+```
+1、需要注意的是default 的 **revision** 属性代表着之后提交PR的目标分支    
+2、不同的项目也可以有不同的 **revision** ，也就是说之后提交PR的目标分支也可不同， **revision** 的优先级由低到高  
+3、fetch当前只支持gitee的ssh  
+
+### 1.repo 引导命令安装
+```shell
+# python3版本 向下兼容 
+curl https://gitee.com/MarineJ/repo/raw/master/repo-py3 > /usr/local/bin/repo
+
+chmod a+x /usr/local/bin/repo
+pip install -i https://pypi.tuna.tsinghua.edu.cn/simple requests
 ```

+### 2.repo初始化与仓库初次同步
+```shell
+mkdir your_project && cd your_project
+repo init -u git@gitee.com:{namespace}/manifest.git
+repo sync
+```
+
+### 3.repo+gitee本地开发流程
+```shell
+repo start {branch} --all #  切换开发分支，当对部分仓库进行指定时，会触发仓库的预先fork
+
+分支开发.........
+
+repo forall -c git add ./git add/repo stage  #  批量加入暂存区或者单独加入
+repo forall -c git commit/git commit  #  批量进行提交或者单独提交
+
+repo config --global repo.token {TOKEN} #  进行gitee access_token配置, access_token获取连接 https://gitee.com/profile/personal_access_tokens
+  
+repo config repo.pullrequest {True/False} #  对是否触发PR进行配置 
+repo push --br={BRANCH} --d={DEST_BRANCH}  #  进行推送并生成PR和审查，执行后会展示出可进行推送的项目，去掉注释的分支会进行后续推送
+
+repo gitee-pr --br={BRANCH} #获取项目推送后的指定分支的PR列表  
+ 
+```
+ **repo push**  参数介绍

+1、其中值得注意的是 **--dest_branch** 和 **--br** 参数，如果不填写对应的分支的话会基于默认分支进行操作， **--br** 默认会以当前分支进行提交， **--dest_branch** 会以manifest.xml中的default  **revision** 作为默认目标分支  
+2、当repo push对仓库进行推送时，会默认向与token相关的用户个人namespace下的仓库推送，在切换分支时没有预先fork成功，则在repo push失败时会再次以token关联的用户对上游仓库进行fork，fork成功后再次push即可  
+3、repo push默认会以ssh方式向token关联的用户的namespace下进行仓库推送，若需要改为https，则可根据repo config repo.pushurl {用户域名空间地址如:https://gitee.com/xxxx}

+1、在 --br={BRANCH} 参数情况下直接返回指定分支下，在gitee平台上已经提交过的PR
