I saw a bunch of stars pop up and thought I should mention that tokei is smarter and more accurate so please give that a l
B4FA
ook and see if there are any wild discrepancies (mostly for your benefit but please let me know if so). Tokei is linked below but it's also rust so cargo install tokei is all you need. Also these benchmarks are quite old. I doubt cloc has changed but tokei probably has.
loc is a tool for counting lines of code. It's a rust implementation of cloc, but it's more than 100x faster. There's another rust code counting tool called tokei, loc is ~2-10x faster than tokei, depending on how many files are being counted.
I can count my 400k file src directory (thanks npm) in just under 7 seconds with loc, in a 1m14s with tokei, and I'm not even willing to try with cloc.
Counting just the dragonflybsd codebase (~9 million lines):
- loc: 1.09 seconds
- tokei: 5.3 seconds
- cloc: 1 minute, 50 seconds
There are binaries available on the releases page, thanks to the wonderful rust-everywhere project and travisci. For anyone familiar with Rust there's cargo install loc.
If you want to install Rust/Cargo, this is probably the easiest way: https://www.rustup.rs/.
loc should now compile on Windows, but you can also run it under Windows using linux emulation:
You can run
locon Windows 10 Anniversary Update build 14393 or later using the Windows Subsystem for Linux. Simply download the Linux distribution from the releases page, and run it inbashusing a WSL-compatible path (e.g./mnt/c/Users/Foo/Repo/instead ofC:\Users\Foo\Repo).
By default, loc will count lines of code in a target directory:
$ loc

--------------------------------------------------------------------------------Fortran has a rule that comments must start with the first character of a line. I only check if it's the first non-whitespace character of a line. I don't know how often this is a problem in real code. I would think not often.
Comments inside string literals: You can get incorrect counts if your code has something like this:
x = "/* I haven't slept \
for 10 days \
because that would be too long \
*/";
loc counts the first line and last lines correctly as code, but the middle lines will be incorrectly counted as comments.
Ignored and hidden files:
By default, loc respects .gitignore/.ignore files, and ignores hidden files and directories. You can count disregard
ignore files with loc -u, and include hidden files/dirs with loc -uu.
