Simple script to count NLOC?

Question

Do you know a simple script to count NLOCs (netto lines of code). The script should count lines of C Code. It should not count empty lines or lines with just braces. But it doesn't need to be overly exact either.

Answer 1

Not a script, but you can try this command-line open source tool: NLOC

Answer 2

SLOCCOunt is not a simple script and does much more than what you need. However, it is a powerful alternative to the already mentioned Ohcount and NLOC. :)

Answer 3

I usually just do this:

grep -vc '^$' (my files)

Works only if your empty lines are really empty (no spaces). Sufficient for me.

Answer 4

Check out DPack plugin for Visual Studio. It has a stats report for any solution/project.

Answer 5

Source monitor is freeware source analysis software. It is windows application but it also can be run with parameters from command line.

It can analyze C++, C, C#, VB.NET, Java, Delphi, Visual Basic (VB6) or HTML.

Answer 6

I would do that using awk & cpp (preprocessor) & wc . awk removes all braces and blanks, the preprocessor removes all comments and wc counts the lines:

find . -name \*.cpp -o -name \*.h | xargs -n1 cpp -fpreprocessed -P | 
    awk '!/^[{[:space:]}]*$/' | wc -l

If you want to have comments included:

find . -name \*.cpp -o -name \*.h | xargs awk '!/^[{[:space:]}]*$/' | wc -l
