integrate Beyond Compare with ClearCase

Question

Hi,

I would like to integrate Beyond Compare with ClearCase so that I can use it for diffing and merging files, instead of the awful tools provided by ClearCase.

Does anyone have instructions for performing this integration?

Thanks, Don

Answer 1

As mentioned in my previous answer, just modify the map file located in:

# up to ClearCase 7.0
c:\program files\rational\ClearCase\lib\mgrs

or

# ClearCase 7.1 and more
c:\program files\IBM\RationalSDLC\ClearCase\lib\mgrs

Each map line has 3 parts: the CC filetype, the CC action, and the application.

In your case, find the section in the map file for text_file_delta file types.
There you will find lines for CC actions compare, xcompare, merge, and xmerge.

Use BeyondCompare:

text_file_delta xcompare C:\Progra~1\Beyond~1\bc2.exe  

Beyond Compare 3 support all CC actions:

text_file_delta compare C:\Program Files\Beyond Compare 3\BComp.exe
text_file_delta xcompare C:\Program Files\Beyond Compare 3\BComp.exe
text_file_delta merge C:\Program Files\Beyond Compare 3\BComp.exe
text_file_delta xmerge C:\Program Files\Beyond Compare 3\BComp.exe 

Note: For Beyond Compare 2, this page clearly mentions

To use Beyond Compare 2, only change the xcompare line of the map file.
Overriding compare, merge, and xmerge is not supported.
A helper that improves BC2's support is available here.
