       cloc - Count, or compute differences of, lines of source code and comments.


         cloc [options] <FILE|DIR> ...


       Count, or compute differences of, physical lines of source code in the given files (may be
       archives such as compressed tarballs or zip files, or git commit hashes or branch names)
       and/or recursively below the given directories.  It is written entirely in Perl, using
       only modules from the standard distribution.


   Input Options
       To count standard input, use the special filename - and either --stdin-name=FILE to tell
       cloc the name of the file being piped in, or --force-lang=LANG to apply the LANG counter
       to all input.

           This option is only needed if cloc is unable to figure out how to extract the contents
           of the input file(s) by itself. Use CMD to extract binary archive files (e.g.:
           .tar.gz, .zip, .Z). Use the literal '>FILE<' as a stand-in for the actual file(s) to
           be extracted. For example, to count lines of code in the input files gcc-4.2.tar.gz
           perl-5.8.8.tar.gz on Unix use:

               --extract-with='gzip -dc >FILE< | tar xf -

           or, if you have GNU tar:

               --extract-with='tar zxf >FILE<'

           and on Windows, use, for example:

               --extract-with="\"c:\Program Files\WinZip\WinZip32.exe\" -e -o >FILE<

           Take the list of file and/or directory names to process from FILE, which has one
           file/directory name per line.  Only exact matches are counted; relative path names
           will be resolved starting from the directory where cloc is invoked.  See also

           Invoke a system call to VCS to obtain a list of files to work on.  If VCS is 'git',
           then will invoke 'git ls-files' to get a file list and 'git submodule status' to get a
           list of submodules whose contents will be ignored.  See also --git which accepts git
           commit hashes and branch names.  If VCS is 'svn' then will invoke 'svn list -R'.  The
           primary benefit is that cloc will then skip files explicitly excluded by the
           versioning tool in question, ie, those in .gitignore or have the svn:ignore property.
           Alternatively VCS may be any system command that generates a list of files.  Note:
           cloc must be in a directory which can read the files as they are returned by VCS.
           cloc will not download files from remote repositories.  'svn list -R' may refer to a
           remote repository to obtain file names (and therefore may require authentication to
           the remote repository), but the files themselves must be local.

           Check binary files to see if they contain Unicode expanded ASCII text.  This causes
           performance to drop noticeably.

   Processing Options
           Count .in files (as processed by GNU autoconf) of recognized languages.  See also

           Report results for every source file encountered.

           Report results for every source file encountered in addition to reporting by language.

       --count-and-diff SET1 SET2
           First perform direct code counts of source file(s) of SET1 and SET2 separately, then
           perform a diff of these.  Inputs may be pairs of files, directories, or archives.  If
           --out or --report-file is given, three output files will be created, one for each of
           the two counts and one for the diff.  See also --diff, --diff-alignment,
           --diff-timeout, --ignore-case, --ignore-whitespace.

       --diff SET1 SET2
           Compute differences in code and comments between source file(s) of SET1 and SET2.  The
           inputs may be pairs of files, directories, or archives.  Use --diff-alignment to
           generate a list showing which file pairs where compared.  See also --count-and-diff,
           --diff-alignment, --diff-timeout, --ignore-case, --ignore-whitespace.

       --diff-timeout N
           Ignore files which take more than N seconds to process.  Default is 10 seconds.
           (Large files with many repeated lines can cause Algorithm::Diff::sdiff() to take

           [Unix only] Follow symbolic links to directories (sym links to files are always

           Process all files that have a EXT extension with the counter for language LANG. For
           example, to count all .f files with the Fortran 90 counter (which expects files to end
           with .f90) instead of the default Fortran 77 counter, use:

                   --force-lang="Fortran 90",f

           If EXT is omitted, every file will be counted with the LANG counter.  This option can
           be specified multiple times (but that is only useful when EXT is given each time). See
           also --script-lang, --lang-no-ext.

           Load language processing filters from FILE, then use these filters instead of the
           built-in filters.  Note:  languages which map to the same file extension (for example:
           MATLAB/Objective C/MUMPS;  Pascal/PHP; Lisp/OpenCL; Lisp/Julia; Perl/Prolog) will be
           ignored as these require additional processing that is not expressed in language
           definition files.  Use --read-lang-def to define new language filters without
           replacing built-in filters (see also --write-lang-def).

           Forces the inputs to be interpreted as git targets (commit hashes, branch names, et
           cetera) if these are not first identified as file or directory names.  This option
           overrides the --vcs=git logic if this is given; in other words, --git gets its list of
           files to work on directly from git using the hash or branch name rather than from 'git
           ls-files'.  This option can be used with --diff to perform line count diffs between
           git commits, or between a git commit and a file, directory, or archive.  Use
           -v/--verbose to see the git system commands cloc issues.

           Ignore horizontal white space when comparing files with --diff.  See also

           Ignore changes in case; consider upper- and lowercase letters equivalent when
           comparing files with --diff.  See also --ignore-whitespace.

           Count files without extensions using the LANG counter.  This option overrides internal
           logic for files without extensions (where such files are checked against known
           scripting languages by examining the first line for "#!").  See also --force-lang,

           Skip files larger than "MB" megabytes when traversing directories.  By default,
           "MB"=100.  cloc's memory requirement is roughly twenty times larger than the largest
           file so running with files larger than 100 MB on a computer with less than 2 GB of
           memory will cause problems.  Note:  this check does not apply to files explicitly
           passed as command line arguments.

           Ignore files generated by code-production systems such as GNU autoconf.  To see a list
           of these files (then exit), run with --no-autogen list See also --autoconf.

           Process binary files in addition to text files. This is usually a bad idea and should
           only be attempted with text files that have embedded binary data.

           Load new language processing filters from FILE and merge them with those already known
           to cloc.  If FILE defines a language cloc already knows about, cloc's definition will
           take precedence.  Use --force-lang-def to over-ride cloc's definitions.  (see also

           Process all files that invoke "S" as a "#!" scripting language with the counter for
           language LANG. For example, files that begin with "#!/usr/local/bin/perl5.8.8" will be
           counted with the Perl counter by using


           The language name is case insensitive but the name of the script language executable,
           "S", must have the right case. This option can be specified multiple times. See also

           Use DIR as the scratch directory instead of letting File::Temp chose the location.
           Files written to this location are not removed at the end of the run (as they are with

           Skip the file uniqueness check. This will give a performance boost at the expense of
           counting files with identical contents multiple times (if such duplicates exist).

           Count lines streamed via STDIN as if they came from a file named FILE.

           For each file processed, write to the current directory a version of the file which
           has blank and commented lines removed (in-line comments persist). The name of each
           stripped file is the original file name with ".EXT" appended to it. It is written to
           the current directory unless --original-dir is on.

           Write the stripped files the same directory as the original files.  Only effective in
           combination with --strip-comments.

           Input arguments are report files previously created with the --report-file option.
           Makes a cumulative set of results containing the sum of data from the individual
           report files.

           [Available only on systems with a recent version of the Parallel::ForkManager module.
           Not available on Windows.] Sets the maximum number of cores that cloc uses.  The
           default value of 0 disables multiprocessing.

           Over-ride the operating system detection logic and run in UNIX mode.  See also
           --windows, --show-os.

           If SLOCCount is installed, use its compiled executables c_count, java_count,
           pascal_count, php_count, and xml_count instead of cloc's counters.  SLOCCount's
           compiled counters are substantially faster than cloc's and may give a performance
           improvement when counting projects with large files.  However, these cloc-specific
           features will not be available: --diff, --count-and-diff, --strip-comments, --unicode.

           Over-ride the operating system detection logic and run in Microsoft Windows mode.  See
           also --unix, --show-os.

   Filter Options
       --exclude-dir=DIR1[,DIR2 ...]
           Exclude the given comma separated directories from being scanned. For example:


           will skip all files that match "/.cache/" or "/test/" as part of their path.
           Directories named ".bzr", ".cvs", ".hg", ".git", and ".svn" are always excluded.  This
           option only works with individual directory names so including file path separators is
           not allowed.  Use --fullpath and --not-match-d=REGEX to supply a regex matching
           multiple subdirectories.

       --exclude-ext=EXT1[,EXT2 ...]
           Do not count files having the given file name extensions.

       --exclude-lang=L1[,L2 ...]
           Exclude the given comma separated languages from being counted.

           Ignore files and/or directories whose names appear in FILE.  FILE should have one file
           name per line.  Only exact matches are ignored; relative path names will be resolved
           starting from the directory where cloc is invoked.  See also --list-file.

           Modifies the behavior of --match-f or --not-match-f to include the file's path in the
           regex, not just the file's basename.  (This does not expand each file to include its
           absolute path, instead it uses as much of the path as is passed in to cloc.)

       --include-lang=L1[,L2 ...]
           Count only the given comma separated languages L1, L2, L3, et cetera.

           Only count files in directories matching the Perl regex.  For example


           only counts files in directory paths containing "/src/" or "/include/".

           Count all files except in directories matching the Perl regex.  Only the trailing
           directory name is compared, for example, when counting in "/usr/local/lib", only "lib"
           is compared to the regex.  Add --fullpath to compare parent directories to the regex.
           Do not include file path separators at the beginning or end of the regex.

           Only count files whose basenames match the Perl regex. For example this only counts
           files at start with Widget or widget:


           Add --fullpath to include parent directories in the regex instead of just the

           Count all files except those whose basenames match the Perl regex.  Add --fullpath to
           include parent directories in the regex instead of just the basename.

           Ignore files that end with the given Perl regular expression.  For example, if given
             --skip-archive='(zip|tar(\.(gz|Z|bz2|xz|7z))?)'  the code will skip files that end
           with .zip, .tar, .tar.gz, .tar.Z, .tar.bz2, .tar.xz, and .tar.7z.

           On Windows, ignore hidden files.

   Debug Options
           Save names of categorized files to FILE.

           Save names of processed source files to FILE.

           Write to FILE a list of files and file pairs showing which files were added, removed,
           and/or compared during a run with --diff.  This switch forces the --diff mode on.

           Print the filters used to remove comments for language LANG and exit.  In some cases
           the filters refer to Perl subroutines rather than regular expressions.  An examination
           of the source code may be needed for further explanation.

           Print cloc's internal usage information and exit.

           Save names of every file found to FILE.

           Save names of ignored files and the reason they were ignored to FILE.

           Print to STDOUT processed source code before and after each filter is applied.

           Print information about all known (or just the given) file extensions and exit.

           Print information about all known (or just the given) languages and exit.

           Print the value of the operating system mode and exit.  See also --unix, --windows.

           Turn on verbose with optional numeric value.

           Long form of -v.

           Print the version of this program and exit.

           Writes to FILE the language processing filters then exits. Useful as a first step to
           creating custom language definitions. See also --force-lang-def, --read-lang-def.

   Output Options
       --3 Print third-generation language output.  (This option can cause report summation to
           fail if some reports were produced with this option while others were produced without

       --by-percent X
           Instead of comment and blank line counts, show these values as percentages based on
           the value of X in the denominator:

               X = 'c'   -> # lines of code
               X = 'cm'  -> # lines of code + comments
               X = 'cb'  -> # lines of code + blanks
               X = 'cmb' -> # lines of code + comments + blanks

           For example, if using method 'c' and your code has twice as many lines of comments as
           lines of code, the value in the comment column will be 200%.  The code column remains
           a line count.

           Write the results as comma separated values.

           Use the character C as the delimiter for comma separated files instead of ,.  This
           switch forces --csv to be on.

           Write the results in JavaScript Object Notation (JSON).

           Write the results as Markdown-formatted text.

           Synonym for --report-file=FILE.

           Show progress update after every N files are processed (default N=100). Set N to 0 to
           suppress progress output; useful when redirecting output to STDOUT.

           Suppress all information messages except for the final report.

           Write the results to FILE instead of standard output.

           Write results as SQL CREATE and INSERT statements which can be read by a database
           program such as SQLite. If FILE is -, output is sent to STDOUT.

           Append SQL insert statements to the file specified by --sql and do not generate table
           creation option.

           Use name as the project identifier for the current run. Only valid with the --sql

           Write SQL statements in the given style instead of the default SQLite format.
           Currently, the only style option is Oracle.

           For plain text reports, show the SUM: output line even if only one input file is

           Write the results in XML.

           Reference FILE as an XSL stylesheet within the XML output. If FILE is not given,
           writes a default stylesheet, cloc.xsl. This switch forces --xml to be on.

           Write the results in YAML.


       Count the lines of code in the Perl 5.10.0 compressed tar file on a UNIX-like operating

         cloc perl-5.10.0.tar.gz

       Count the changes in files, code, and comments between Python releases 2.6.6 and 2.7:

         cloc --diff  Python-2.7.tar.bz2

       To see how cloc aligns files for comparison between two code bases, use the
       --diff-alignment=FILE option.  Here the alignment information is written to "align.txt":

         cloc --diff-aligment=align.txt gcc-4.4.0.tar.bz2  gcc-4.5.0.tar.bz2

       Count file, code, and comment changes between two git commits:

         cloc --git --diff b409850824 HEAD

       Print the recognized languages:

         cloc --show-lang

       Remove comments from "foo.c" and save the result in "" ("nc" is an arbitrary
       extension; used here to denote "no comments"):

         cloc --strip-comments=nc foo.c
