Cornerstone 3 添加外部diff工具

因Mac上的svn工具Cornerstone的diff工具十分不好用，并且比对不精确，所以想在Cornerstone内调用第三方diff工具。个人使用DiffFork进行比对。

DiffFork还提供shell方式打开软件可以软链到/usr/local/bin/difffork


但是我通过shell方式打开后是生成了2个比对窗口，2个文件没能在一起比对，所以使用了applescript方式。
但是BeyondCompare可以通过shell方式正确打开，但是Mac下的BeyondCompare对中文不友好所以就用DiffFork了。
shell调用方式：

#!/bin/bash

original_path="$1"
modified_path="$3"

/usr/local/bin/bcompare "$original_path" "$modified_path"

DiffFork提供的applescript调用示例：

(*
diff v: Diff
   diff item : the old item.
      against item : the new item.
*)

set theOld to (choose file with prompt "Select Old:")
set theNew to (choose file with prompt "Select New:")

tell application "DiffFork"
    activate
    diff theOld against theNew
end tell

因为Cornerstone的外部工具只支持*.sh的所以修改了DiffFork提供的applescript以shell方式打开。

#!/bin/bash

osascript -e 'tell application "DiffFork"' -e "activate" -e "diff \"$1\" against \"$3\"" -e 'end tell'

下面是BeyondCompare的调用方式：

#!/bin/bash

original_path="$1"
modified_path="$3"

/usr/local/bin/bcompare "$original_path" "$modified_path"
