cloc

counts blank lines, comment lines,

and physical lines of source code in .

Given two versions of a code base, cloc can compute

differences in blank, comment, and source lines.

It is written entirely in Perl with no dependencies outside the

standard distribution of Perl v5.6 and higher

(code from some external modules is )

and so is quite portable.

cloc is known to run on many flavors of Linux,

Mac OS X, AIX, Solaris, IRIX, z/OS, and Windows.

(To run the Perl source version of cloc on Windows one needs

ActiveState Perl 5.6.1 or higher, Cygwin, or MobaXTerm with

the Perl plug-in installed.

Alternatively one can use the

Windows binary of cloc generated with

to run on Windows computers that have neither Perl nor Cygwin.)

cloc contains code from David Wheeler's

,

Damian Conway and Abigail's Perl module

,

Sean M. Burke's Perl module

, and Tye McQueen's Perl module

.

Language scale factors were derived from Mayes Consulting, LLC web site .

cloc has many features that make it easy to use, thorough,

extensible, and portable:

1. Exists as a single, self-contained file that requires minimal
   installation effort---just download the file and run it.
2. Can read language comment definitions from a file and thus
   potentially work with computer languages that do not yet exist.
3. Allows results from multiple runs to be summed together
   by language and by project.
4. Can produce results in a variety of formats:
   plain text, SQL, XML, YAML, comma separated values.
5. Can count code within compressed archives (tar balls, Zip files,
   Java .ear files).
6. Has numerous troubleshooting options.
7. Handles file and directory names with spaces and other unusual
   characters.
8. Has no dependencies outside the standard Perl distribution.
9. Runs on Linux, FreeBSD, NetBSD, Mac OS X, AIX, HP-UX, Solaris, IRIX,
   and z/OS systems that have Perl 5.6 or higher.
   The source version runs on Windows with either ActiveState
   Perl or cygwin. Alternatively on Windows one can run
   the Windows binary which has no dependencies.
