How many lines of code modified during a time period?

Question

I have been tasked with figuring out how many lines of code I've written this year. Not very exciting for a number of reasons, but it seems like it could make a nice SO question.

So in your favorite version control tool, how do you tell how many lines of code have been modified? In my particular answer blank lines and comments happen to count to simplify the time allotted to determining the answer, but feel free to elaborate.

In my particular case I'm using svn, so I'm going to get rid of all the --- and other misc output that svn log and svn diff output.

Answer 1

I'd just try and get an idea of what management thought would be good, then tell them a number that is way bigger than that. You can spend the rest of the week reading Dilbert.

Answer 2

Use StatSVN. I use it at work and it's great, it'll break down LOC by developer by month. It'll draw pretty graphs, tell you what day of the week and what time you check in the most code. It'll tell you exactly what you need to know.

Answer 3

Fisheye can tell you how many lines of code were committed per developer. There is a nice charting feature that can give you pretty graphs for this.

Answer 4

In Clearcase, take the config spec and add:

time  <date-time>
<rules for choosing branches or labels>
end time

Make a second view, and compare the two. If multiple developers are working on the same files, I have no clue. I can't say I'm thrilled by using Clearcase, ever.

Answer 5

If you are using subversion you can use the svn log command with the --xml switch and you can pull the lines of code from there. You can see the options of svn log using svn help log. Since your output is xml you can run through this xml and aggregate your line counts in code and go from there.
