Followup: Managing EXCEL with git - diff problem.

2015-04-07 Thread Randall S. Becker
Hi all,

There was a discussion a while back on how to manage EXCEL content in git.
This involved a simple trick of modifying the file extension from .xlsx to
.zip and unpacking the file - resulting in a whole bunch of XML files. Git
is happy with that part and the content can be managed - slightly.

Unfortunately, EXCEL stores its XML content in single lines. Git has no
problem with that either, as far as managing the content, but the lines can
be really long. However, after about 20K in size, while the config:

alias.wdiff=diff --color-words

The ability of git to report differences goes away - as in no output from
git diff. This occurs on Windows and Linux under git 2.3.3 and git 2.3.0.
I'm not sure whether this is a user error, a usage error, or an actual
problem.

I had originally raised this as a SourceTree problem figuring it might be
there: https://jira.atlassian.com/browse/SRCTREEWIN-3145

Any advice (preferably no teasing - :-) - I am considering smudging but
would rather avoid that)?

Cheers,
Randall

Perhaps try defining a specific diff driver for these files (see
git-attributes(5)).  There is an xmldiff program [0] that might be able
to generate more useful diffs.
