Linecount

This page is to measure the number of lines of source code of various types of program. That is useless for spotting extremely lean/minimal/simple programs and detecting insanity/bloat/excessive complexity.

The measurements are usually .c then .h.

If anything is wrong please feel free to update it or inform me.


 * This site has line counts for lots of software: https://www.openhub.net/


 * funny page where they boast about having loads of lines of code https://www.f35.com/about/life-cycle/software

Script
Here is a script to count lines of code:

find "$1" -name "$2" -exec wc -l {} \; | awk '{ SUM += $0 } END { print SUM }'

Thanks to http://stackoverflow.com/questions/1358540/how-to-count-all-the-lines-of-code-in-a-directory-recursively/16212299#16212299

it's important not to use xargs, there might be more files that command line handles. This is silently ignored and you get wrong results.

Shells
In the case of scsh we measure .scm, .c, .h

gnu bash:    138227,  13746 zsh:         135589,   5698 shivers scsh: 118475, 27131, 1985 templeos:    119115,      0 mirbsd mksh:  29223,   2562 obsd ksh:     23700,   1439 debian dash:  16503,   2084 freebsd sh:   15453,   1622 es shell:      9017,   1436 plan9 rc:      5989,    327 execline:      3794,    117

bash has the highest linecount here. I think that is part of why the shellshock vulnerability happened.

Kernels

 * for plan9: Just the stuff inside `plan9/sys/src/9/`
 * for minix3: `minux/kernel`, which according to http://wiki.minix3.org/doku.php?id=developersguide:overviewofminixuserland contains the minix kernel, in the minix-specific portion of the NetBSD source tree that minix uses
 * for Mezzano by froggey, .lisp only, count the whole OS (includes a compiler, desktop programs).
 * sortix is .cpp.
 * toaruos, haiku and freeDOS is .c, .h, .S (assembly).
 * msdos 2.0 is thanks to http://www.computerhistory.org/atchm/microsoft-research-license-agreement-msdos-v1-1-v2-0/ and the code is in .ASM
 * xnu-3247.1.106 fetched from http://opensource.apple.com/release/os-x-1011/

C Compilers

 * clang also includes LLVM and CFE, is also in C++.
 * gcc also contains some C++ code, this is in the third column (first are .c and .h).
 * These probably contain some assembly files, these were not included.
 * 8cc is only 7000 lines without tests. Maybe we should delete tests before counting?

gcc-6.1.0:   2854201, 379272,   598 clang-3.8.0: 1523165, 169972 pcc-20160429: 112891,   9855 tcc-0.9.26:    36689,  39835 lcc-4.2:       25504,   3637 8cc:           10874,    718

web engines

 * webkitgtk and dillo is c++
 * servo is in rust, we count .rs then: find . -name '*.rs' -exec grep 'unsafe' {} \; | wc
