How to count the number of changed or added lines in an SVN branch?

Question

I would like to add up the number of line changes in an SVN branch so I can tell how far I have gone during a project from another side and estimate the probability of conflict when I merge it with trunk.

The way I can think of is to grab the unified diff and do some grep|wc -l hacks, but the problem is it's hard to separate different file types, for example, front-end source files (.css, .html) and back-end source files(.xml, .java)

Answer 1

Cosidering beginRev as the initial revision of the changeset you want to measure and endRev as the final revision:

svn diff --summarize -rbeginRev:endRev <URLtoBranch>

This will give you the output of files added, deleted and modified.

I you want more detail level you could parse the svn diff output through diffstat:

svn diff -rbeginRev:endRev <URLtoBranch> | diffstat

This will return an histogram of the changes with information for each file, and a summary of files changed, lines added and deleted.
