git 很好很強大...

（前情提要：我把某一段程式碼，從一個檔案 cut 下來，paste 到另一檔案）

雖然剛剛看了 redmine 的 svn diff,
好像也會顯示不同檔案間程式碼的移動？
不過看起來就怪怪的，如果我不知道他是移動的話，
應該會看不懂才對，因為沒什麼說明，
而且變成兩個不同的檔案在做 diff @@

但是在 git commit -a 時，看到神奇的訊息，讓我吃了 LCD:

* added app_ext for AbstractRequest patch, which extracted from photos/upload.rb
                for ActiveRecord::Base.exists_and_find

# Please enter the commit message for your changes.
# (Comment lines starting with '#' will not be included)
# On branch master
# Changes to be committed:
#   (use "git reset HEAD ..." to unstage)
#
#       renamed:    lib/ffbapi/photos/upload.rb -> config/initializers/app_ext.rb
#       modified:   lib/ffbapi/photos/upload.rb

噢，他居然知道我程式碼是從 upload.rb 移動到 app_ext.rb @_@

commit 完之後的訊息是：

godfat ~/p/g/photo_app> git commit -a
Created commit 183997a: * added app_ext for AbstractRequest patch,
                          which extracted from photos/upload.rb
 2 files changed, 22 insertions(+), 151 deletions(-)
 rename lib/ffbapi/photos/upload.rb => config/initializers/app_ext.rb (90%)
 rewrite lib/ffbapi/photos/upload.rb (90%)
godfat ~/p/g/photo_app>

他知道移動了 90% 的 code @_@
雖然說 rename 這個詞似乎有點不直接就是了...

上傳：

godfat ~/p/g/photo_app> git svn dcommit

為什麼是 C 啊 @_@ 看起來不是 conflict 的意思...
總覺得應該再多看一點 git 的概念的，可惜一直沒仔細讀過。

gitk 裡則這樣顯示：

---------- config/initializers/app_ext.rb ----------
similarity index 90%
copy from lib/ffbapi/photos/upload.rb
copy to config/initializers/app_ext.rb
index cd39bc4..1ec4ac3 100644

這就非常容易看懂了 XDD
