Git在Windows环境下配置Diff以及Merge工具---DiffMerge

参考出处：http://coding4streetcred.com/blog/post/Configure-DiffMerge-for-Your-Git-DiffTool主要转自：http://blog.csdn.net/u010232305/article/details/51767887

1、下载DiffMerge

http://sourcegear.com/diffmerge/downloads.php，楼主选择的是 Windows Installer (64bit)，安装直接下一步，这一版只能安装在C盘

2、创建启动DiffMerge脚本

（1）在Git的安装路径的\cmd路径下创建以下两个脚本

git-difftool-diffmerge-wrapper.sh内容为

 # place this file in the Windows Git installation directory /cmd folder
 # be sure to add the ../cmd folder to the Path environment variable

 #  parameters:
 # path old-file old-hex old-mode new-file new-hex new-mode

 "C:\Program Files\SourceGear\Common\DiffMerge\sgdm.exe" "$1" "$2" | cat

git-mergetool-diffmerge-wrapper.sh内容为

 # place this file in the Windows Git installation directory /cmd folder
 # be sure to add the ../cmd folder to the Path environment variable

 # passing the following parameters to mergetool:
 # local base remote merge_result

 "C:\Program Files\SourceGear\Common\DiffMerge\sgdm.exe""$1""$2""$3" --result="$4" --title1="Mine" --title2="Merge" --title3="Theirs"

注意：其中的路径名为安装后的DiffMerge.exe的实际路径名，楼主的为”C:/Program Files/SourceGear/Common/DiffMerge/sgdm.exe”

（2）将\cmd设置环境变量，方便找

将git程序的cmd目录加入环境变量Path，楼主的为"C:\Program Files\Git\cmd"

3、修改Git配置

找到.gitconfig文件（路径在Windows“用户”路径下）

upsert以下内容：

 [merge]
     tool = diffmerge
 [diff]
     tool = diffmerge
 [mergetool]
     keepBackup = false
 [mergetool "diffmerge"]
     cmd = git-mergetool-diffmerge-wrapper.sh "$LOCAL" "$BASE" "$REMOTE" "$MERGED"
 [difftool "diffmerge"]
     cmd = git-difftool-diffmerge-wrapper.sh "$LOCAL" "$REMOTE"

4、OK

当merge出现冲突的时候，输入 
git mergetool 
diffmerge就出来啦
