git submodule的使用

在UseShareLibraryProject1 project裡加入ShareLibrary project


1. git submodule add git@github.com:deeplovepan/ShareLibrary.git
   將ShareLibrary抓下來

2. git commit
    commit ShareLibrary和.gitmodules
 
3. git submodule init
   更新.git/config
  ->
  多了
  [submodule "ShareLibrary"]
   url = git@github.com:deeplovepan/ShareLibrary.git

在UseShareLibraryProject1裡修改submodule ShareLibrary

1. cd ShareLibrary/ShareLibrary, modify ShareLibraryAppDelegate.m

2. git add ShareLibrary/ShareLibraryAppDelegate.m

3. git commit

4. git push

   從push只修改到github上的ShareLibrary project

5. 回到UseShareLibraryProject1根目錄, 從根目錄commit和push，

   如果才會更新UseShareLibraryProject1採用的submodule版本

6. git add ShareLibrary

7. git commit

8. git push

其它人抓取UseShareLibraryProject1

1. git clone git@github.com:deeplovepan/UseShareLibraryProject1.git

2. git submodule init
    更新.git/config，多了submodule的資訊

3. git submodule update
    抓取submodule內容


其它人更新UseShareLibraryProject1

1. git pull
   更新紀錄的submodule資訊，此時打git submoule，
   若開頭有+，表示submodule內容有修改，需更新
   ex:
   +be295206e07a1eeb6243fa5ee2466c1f6e990e94 ShareLibrary
 
2. git submodule update
   若submodule有更新，抓取submodule內容



只針對UseShareLibraryProject1下的ShareLibrary更新，因為github上的ShareLibrary project有修改



1. 切換至UseShareLibraryProject1下的ShareLibrary

2. git pull origin master

3. 回到UseShareLibraryProject1根目錄
   此時打git submodule將出現以下訊息
   +27c6861c06fdb3a9c82d9b70d41f6287bc068961 ShareLibrary (remotes/origin/HEAD)
   開頭的+表示submodule被更動了
 
4. git add ShareLibrary

5. git commit
   此時再打git submodule，開頭的+不見了
   27c6861c06fdb3a9c82d9b70d41f6287bc068961 ShareLibrary
 
6. git push
