Calling BC4 from Cornerstone SVN

[mryan]

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

After installing the BC4 command line tools, I created an AppleScript wrapper for use by Cornerstone, but it may work with other tools as well.

Here's the script code:

-- Cornerstone executes the script as:
--	/path/to/tool <original> <modified>
--
on run argv
	do shell script "/usr/local/bin/bcomp \"" & item 1 of argv & "\" \"" & item 2 of argv & "\""
end run

Thanks very much for sharing.

Yes, thank you.

But shouldn't you be calling with bcompare instead of bcomp?

[Chris]

bcomp is correct when launching from a version control on Mac.

bcompare launches a comparison and returns immediately. bcomp launches a comparison and waits to return until the comparison is closed. If you use bcompare, the version control system won't detect when the comparison is complete and it might clean up temp files prematurely.

Calling BC4 from Cornerstone 3 SVN Client

The above script did not worked for me, I had to modify it as follow for Cornerstone 3:

-- Cornerstone executes the script as:
-- /path/to/tool <original> <modified>
--
on run argv
   do shell script "/usr/local/bin/bcomp \"" & item 1 of argv & "\" \"" & item 3 of argv & "\" | exit 0"
end run

Hello,

BComp is expected the parameters for two files to diff when called as a diff tool, or 4 files if used as a mergetool. It looks like Cornerstone may have updated their item numbering? I found this official documentation:
