# NAME

copyright-update - Update Copyright information in files

# SYNOPSIS

      copyright-update [options] FILE [FILE ...]
      copyright-update [options] --recursive PATH [PATH ...]

# DESCRIPTION

Update the copyright information in set of files, possibly recursively, matching content criteria. The updating affects copyright year, GPL address information etc.

The line must have word "Copyright", a space, three characters '(C)' (or a U+00A9 UTF copyright sign), a space, and the range of years. Varying amount of spaces and tabs are permitted, but there must be no spaces around the dash-character in YEAR-YEAR. Examples:

                A whitespace, or multiple, required
                |   |           No space between years
                |   |           |
       Copyright (C)        YYYY-YYYY
       Copyright: (C)       YYYY-YYYY
                |
                A colon is optional

By default certain files and paths are always ignored; like version control directories, backups files, object files and binary files according to Perl's `-T` file test. Run program with option --help-exclude to see exclude path list.

# OPTIONS

## Run options

-a, --auto

  In automatic mode, the author's name is read from environment variable NAME and only lines matching 'Copyright.*$NAME' are affected. If NAME is not set, read information from EMAIL.

  If neither NAME nor EMAIL exists in evenvironemt, or if their values are not in a recognizable formats (see section ENVIRONMENT), this options does nothing.

  This option effectively tries to preset value for the --line option.

-c, --code

  Preset --include to match common code files: .c, .h, .cc, .hh, .cpp, .c++, .hpp, .C, .pl, .py, .sh and .rb

-d, --debug LEVEL

  Turn on debug. Level can be in range 0-10.

-f, --fsf-address

  Change License paragraphs that refer to FSF address. The FSF's current recommendation is to redirect inquiries about licences to their URL.

  Effectively replace paragraphs:

        You should have received a copy of the GNU General Public License
        along with this program; if not, write to the Free Software
        Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA

        You should have received a copy of the GNU General Public License
        along with this package; if not, write to the Free Software
        Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301USA

  With this:

        You should have received a copy of the GNU General Public License
        along with this program. If not, see <http://www.gnu.org/licenses/>.

-i, --include REGEXP

  Include files matching regexp. The match is done against whole path.

  If this option is not supplied, every file is automatically included. The matches can be further filtered by using option --exclude.

  This option can be used multiple times. See also option --code.

-l, --line REGEXP

  Change only lines which match REGEXP. The match is case-insensitive.

-r, --recursive

  Recursively search all directories given in command line.

-R, --regexp REGEXP

  Change only files whose content matches REGEXP. The file is read in as a one big string so that it's possible to match using Perl regular expressions across the whole file. An example: '(?smi)This.*multi.*line.*match'. See perlre(1) for more information about 'smi' and other modifiers.

  This option can be used as a preliminary Content criteria, to select files before --line option finds the correct Copyright lines.

-t, --test, --dry-run

  Run in test mode. Show what would happen. No files are changed.

-v, --verbose LEVEL

  Print informational messages. Increase numeric LEVEL for more verbosity.

-x, --exclude REGEXP

  Ignore files matching regexp. The match is done against whole path. The option can be used multiple times.

  This option is applied after possible --include matches.

-y, --year YEAR

  Update files using YEAR. Value must be four digits.

  The default operation is to use currect year, so this option is not necessary in normal use. Use case: you plan to take a long holiday before year's end and want to update the next year's value beforehand.

-Y, --no-year

  Disable updating year.

## Miscellaneus options

-h, --help

  Display help.

--help-exclude

  Display default values used to exclude paths and files.

--help-html

  Display help in HTML format.

--help-man

  Display help in manual page `man(1)` format.

-V, --version

  Display contact and version information.

# EXAMPLES

The primary use is to update files to reflect current year; option --year is implicit:

       copyright-update *

To test what would happen:

       copyright-update --verbose 1 --test *

Update only C-code file:

       copyright-update --verbose 1 --include '\.[ch]$' --recursive .

It is possible to restrict updating files recursively to only those files whose content match regexp. Here, the lines affected are those that match --line regular expression.

       copyright-update \
            --regexp  '(?i)Author:.*John.*Doe' \
            --line    '\bFoo\b' \
            --ignore  '\.(bak|bup|[~#]])$' \
            --verbose 1 \
            --year    2013 \
            --test \
            --recursive \
            .

# TROUBLESHOOTING

See option --debug.

# ENVIRONMENT

EMAIL

  In the form "firstname.lastname@example.com"; that is, without the angles <>. If set, the value is used in option --auto only if environment variable NAME is not set.

  In order to find first and lastname, the localpart in email address must match case insensitive regexp `'^[a-z-]+\.[a-z-]+@'`:

          address@example.com            Not used, not in form First.Last
          +------ +----------

          mr.first.lastname@example.com  Not used, likewise
          +---------------- +----------
          |                 |
          Localpart         Domain part

NAME

  In the form "Firstname Lastname". If set, the value is used in option --auto.
