FWIW I get different results with `cloc`: $ git checkout REL_18_STABLE $ git clean -dfx # be careful! this will drop your local .clangd settings etc $ cloc ./ github.com/AlDanial/cloc v 1.98 T=3.38 s (1448.6 files/s, 915951.4 lines/s) --------------------------------------------------------------------------------------- Language files blank comment code --------------------------------------------------------------------------------------- C 1555 189668 393758 940984 PO File 466 180914 221367 543216 SQL 791 30420 23631 124104 C/C++ Header 973 18935 64368 114176 Perl 335 13402 12264 60254 XML 3 4 15 30922 ... skipped ... --------------------------------------------------------------------------------------- SUM: 4895 446873 728634 1919686 --------------------------------------------------------------------------------------- $ git checkout REL_17_STABLE $ cloc ./ github.com/AlDanial/cloc v 1.98 T=2.68 s (1764.0 files/s, 1104266.3 lines/s) --------------------------------------------------------------------------------------- Language files blank comment code --------------------------------------------------------------------------------------- C 1507 181725 376154 905987 PO File 466 174902 211970 529317 SQL 754 28606 21625 115742 C/C++ Header 943 18255 61771 100741 Perl 309 11882 10905 52974 XML 3 4 15 30922 ... skipped ... --------------------------------------------------------------------------------------- SUM: 4733 428393 695356 1839064 --------------------------------------------------------------------------------------- Overall, there is a 4% increase according to this tool. What is convenient about `cloc` - you can count only what you want, e.g. code without comments, etc. -- Best regards, Aleksander Alekseev
