[dsdp-pmc] How to count lines of code

[Martin Oberhuber <martin.oberhuber@xxxxxxxxxxxxx>]

Hello,

some time ago we had an E-Mail conversation how to count lines of code.
We didn't quite come up with a good solution - taking sloccount for now.

But sloccount by DWheeler has the disadvantage that it does not count 
comments, XML files, build driver files, property files etc. - all of 
which are result of creative work and should thus be counted in the 
spirit of Eclipse, if we want to get an indication for how much IP is in 
some contribution.

I think that I have recently come up with something useful. It works 
fine on Linux and Cygwin:

# Count lines of code in a contribution supplied as archive:
# First extract it, then cd to the toplevel directory, then:
# Cat all non-binary files, suppress empty lines, then count lines
find . -type f | egrep -iv 
'\.(gif|png|jpg|exe|dll|so|a|o|obj|tar|gz|jar|zip)$' | xargs cat | egrep 
-v '^[^a-zA-Z0-9_/*;,.:#<>(){}=+-]*$' | wc -l

# Count lines of code in a contribution that is submitted as a patch
# Cat all lines that were added inthe patch, suppress filename 
specifiers and empty lines
grep '^[+]' patch.txt | grep -v '^[+][+]' | egrep -v 
'^\+[^a-zA-Z0-9_/*;,.:#<>(){}=+-]*$' | wc -l

HTH,
Martin
