Using Beyond Compare４ in MacOS with cmd for svn

Question

I am using the Cornerstone.

The version of Beyond Compare is 4.2.1 (build 22354).

How to using the command line to open Beyond Compare for svn.

I want to set the Beyond Compare as the diff tool for svn.

Comparing Revisions in the Timeline View
To compare two revisions in the timeline view:
Select the first revision by clicking the revision in the timeline.
Select the second revision by holding down the ⌘ key while clicking the revision.
The files are compared in the compare view underneath the timeline. The earlier revision is always displayed on the left.
Folders cannot be compared.

This method is OK.

I don't know how to use AppleScript.

Answer 1

set beyond compare as the diff editor/tool from the svn preferences.

Answer 2

There are instructions for configuring Beyond Compare as Cornerstone's diff tool right on the BC website

In Cornerstone, you can specify a custom external compare script.

Launch Beyond Compare, go to the Beyond Compare menu and run Install Command Line Tools.

DIFF

Create an AppleScript wrapper for use by Cornerstone:

-- Cornerstone executes the script as:
-- /path/to/tool <original> <modified>
--
on run argv
  set original_path to (item 1 of argv)
  set modified_path to (item 3 of argv)
  do shell script "/usr/local/bin/bcomp \"" & original_path & "\" \"" & modified_path & "\""
end run

Set in Preferences | General | External compare tool | Other Script...

Open the AppleScript editor, paste in the script above, save the file and then point BC at the file you just created.

Answer 3

"The command exits when the state is nonzero" You can modify the script from '/usr/local/bin/bcomp' to '/usr/local/bin/bcompare'
