I am counting lines with cloc using this command:
cloc --ignore-case --ignore-whitespace --diff src-copy/file.c src/file.c
and it tells me that I added 103 lines.
When I count the same file with 'git diff' it tells me that I have added 136 lines:
git diff --stat --ignore-blank-lines -w src-copy/file.c src/file.c
How can I verify that cloc counts the lines correctly? Is there any option to output the actual difference of both files, so I can visually inspect and understand why the results of both programs do not match ?
You can get a sense of what cloc thinks is different between the two files by having cloc strip comments from the files then doing a visual diff of the code-only files:
cloc --strip-comments nc --original-dir src-copy/file.c src/file.c
vimdiff src-copy/file.c.nc src/file.c.nc
(or replace vimdiff with the tool of your choice). That will at least eliminate comment differences. Anything flagged by your diff tool should be recognized by cloc as a difference in the count for code changes.
cloc doesn't have an option to show the internals of the diff comparisons. https://github.com/AlDanial/cloc/issues/152 shows a way to add debug statements in the tool to show some of this but the output isn't pretty.
