       cloc - statistics utility to count lines of code


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


       Count physical lines of source code in the given files (may be archives
       such as compressed tarballs or zip files) and/or recursively below the
       given directories. Counts blank lines, comment lines, and physical
       lines of source code in many programming languages. It is written
       entirely in Perl, using only modules from the standard distribution.


   Input Options
           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:

               --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. See also

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

   Processing Options
           Report results for every source file encountered.

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

           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.

           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 from <file> the language processing filters. (see also
           --write-lang-def) then use these filters instead of the built-in

           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 --force-lang.

           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 File::Temp).

           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).

           For each file processed, write to the current directory a version
           of the file which has blank lines and comments removed. 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.

   Filter Options
       --exclude-dir=DIR[,DIR ...]
           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 ".cvs" and ".svn" are always

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

           Ignore files whose names appear in FILE. FILE should have one entry
           per line. Relative path names will be resolved starting from the
           directory where cloc is invoked. See also --list-file.

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


           Count all files except those whose basenames match the Perl regex.

           On Windows, ignore hidden files.

   Debug Options
           Save names of categorized files to FILE.

           Save names of processed source files to FILE.

           Print this usage information and exit.

           Save names of every file found to FILE.

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

           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

           Turn on verbose with optional numeric value.

           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

   Output Options
           Suppress third-generation language output. This option can cause
           report summation to fail f some reports were produced with this
           option hile others were produced without it.)

           Show progress update after every NUMBER files are processed
           (default NUMBER=100). Set NUMBER 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 STDOUT.

           Synonym for --report-file=FILE.

           Write the results as comma separated values.

           Write results as SQL create and insert statements which can be read
           by a database program such as SQLite. If FILE is 1, output is sent
           to stdout.

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

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

           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.


       None (yet).
