Stats for a file.
Hi Everyone,
i would a report of some description that will display how many lines
were edited in a particular set of files between two revisions.
I.e. 1000 lines (combined total) were edit between revision X and HEAD
in a, b, c, d, e, files.
And of course, if it is all possible what might be the required syntax
to obtain such information!
As always, thanks in advance for any assistance.

Funny you should ask for that. I wrote a script yesterday to do that
very thing. However, AT&T owns the script. =/
It will walk each file in each revision for a range of revisions and get
the number of lines added and deleted per file revision in the
revision_range.
The general algorithm was
1) Get the revisions to search
cmd = 'svn log --xml -v --stop-on-copy
-r %d:1 %s' % (head ,branch)
2) Parse the xml to get the filename entries for each revision.
(However, there's no easy way to tell if a filename is a dir or file,
but we don't care (see below)) I used Python's xml.etree.ElementTree
3) Xml: for each logentry in /log
a. Xml: For each path in logentry/paths
i.
If the path/action is 'D', skip it
ii.
(optional) if the path's filename has '/vendor/' skip it
iii. If
path/copyfrom-path attribute exists, skip it (it's a product of 'svn
copy', No free lines for you!)
iv. Get
line count metrics
1. svn_path = url_root + path.text + '@' + str(revision) # Peg
revisions are important, especially if a file's parent dir was renamed
2. svn diff -c$Revision -x "-u -w -ignore-eol-style" svn_path
3. If diff is successful
a. Ignore the first pair of '-' and '++' lines
b. Count the '^-' as deletes
c. Count the '^+' as adds
4. Else diff had an error, which might be ok
a. If the stderr starts with 'svn: Unable to find repository
location for' then
i. We're ok. 'svn diff -c' will fail to run against the very first
revision of a file. We'll run 'svn cat...' instead (see below)
b. Else
i. Unknown error, print a warning
ii. Exit_code = 1
iii. Continue/next
c. For each line in 'svn cat -r $revision' svn _path'
i. Count each line as an add
d. If 'svn cat... ' threw an error, then
i. Ignore any error that starts with 'svn: warning: URL' and ends
with 'refers to a directory'
e. Else
i. Unknown error, print a warning
ii. Exit_code = 1
iii. Continue/next
5. Save statistics
4) Print statistics
5) Exit(exit_code)
'svn diff' won't report on binary files, so no worries there ('svn
diff' returns no data instead of an error.)

I believe that will double (or more) your "changed line" count. I think
in concept something like
diff --side-by-side --suppress-common-lines <foo> <bar> | wc -l
would get a more accurate changed line count. The trick is getting this
to work with "svn diff". The best I could come up with in short order
is:
svn diff --diff-cmd mydiff | egrep -v '^Index:|=+$' | wc -l
where mydiff is the following two-line script:
shift 1
diff --side-by-side --suppress-common-lines "$@"
(The "shift 1" gets rid of the "-u" argument, which conflicts with
--side-by-side.)
