[p4] Getting code velocity metrics from P4?

[Weintraub, David]

Check out "p4 help undoc" (at least in revision 2005.2). They document
the use ">", ">=", "<=", "<", and "=" in revision specifications. For
example, you can find all files that changed between April 1, 2006 and
April 7, 2006 by doing this:

	$ p4 files //..."@>=2006/04/01,<=2006/04/07"

You can also do the same thing with changelists

	$ p4 files //..."@=>1000,@<=1010

Will show you all the files changed between changelist 1000 and 1010.
You have to do quotes in Unix because the shell will interpret the "<"
and ">" as redirections.

Note that

	$ p4 files //... at 1000

Will show you all files as they after changelist 1000 was submitted
while

	$ p4 files //..."@=1000"

shows you only those files that were changed with changelist 1000.

Also note that

	$ p4 files //..."@=2006/04/01"

Shows you only files changed on midnight April 1, 2006 and not all files
changed on April 1, 2006.

Subject: [p4] Getting code velocity metrics from P4?

Has any one scripted a method for getting rate of change metrics in
perforce depots?  

 

For example,  getting numbers of LOC changes between date1 and date2 on
a set of branches ?

Assuming you skip binary files and there may be an exclusion pattern.

 

I think getting the # of changes lists is not too difficult.  

 

Does anyone have anything similar to this?
