Copyright Header is a utility to manipulate licenses on source code.
Features
- Add/remove a copyright headers recursively on source files
- Customize the syntax configuration for how to write out comments
- Built-in support for GPL3 and MIT licenses
- Supports custom licenes with
--license-fileargument - ERB template support
Caveats
- Will only remove headers to files that have exactly the same header as the one we added
- Will only add headers to files which do not contain the case-sensitive pattern
/[Cc]opyright|[Lc]icense/in the firstNlines - Will not properly format arguments that contain new-line ("
\n") characters.
Requirements
- Ruby 1.9.2 (supported version, might work with older rubies but not guaranteed)

Examples
Discover available parameters by passing the --help argument
copyright-header --help
Add a GPL3 License header to a file:
copyright-header --add-path /tmp/test.rb \
--license GPL3 \
--copyright-holder 'Joe Shmoe' \
--copyright-software 'Example Software' \
--copyright-software-description "This is the description of the software." \
--copyright-year 2012-2017 \
--output-dir /tmp \
--dry-run
Remove the header created in the previous step (without --dry-run argument):
copyright-header --remove-path /tmp/test.rb \
--license GPL3 \
--copyright-holder 'Joe Shmoe' \
--copyright-software 'Example Software' \
--copyright-software-description 'This is the description of the software.' \
--copyright-year 2012-2017 \
--output-dir /tmp \
--dry-run
Command used to generate copyright headers for this script:
copyright-header --license GPL3 \
--add-path lib/:bin/ \
--guess-extension \
--copyright-holder 'Erik Osterman <[email protected]>' \
--copyright-software 'Copyright Header' \
--copyright-software-description "A utility to manipulate copyright headers on source code files" \
--copyright-year 2012-2017 \
--word-wrap 100 \
--output-dir ./
Paths can be either files or directories. It will recursively traverse the directory tree ignoring all dot files.
You can specify an alternative syntax configuration file using the --syntax argument.
Rake
The above example can be performed as rake task inside a Rakefile:
task :headers do
require 'rubygems'
require 'copyright_header'
args = {
:license => 'GPL3',
:copyright_software => 'Copyright Header',
:copyright_software_description => "A utility to manipulate copyright headers on source code files",
:copyright_holders => ['Erik Osterman <[email protected]>'],
:copyright_years => ['2012-2017'],
:add_path => 'lib',
:output_dir => '.'
}
command_line = CopyrightHeader::CommandLine.new( args )
command_line.execute
end
Docker
docker run --rm --volume `pwd`:/usr/src/ osterman/copyright-header:latest \
--license GPL3 \
--add-path . \
--guess-extension \
--copyright-holder 'Erik Osteman <[email protected]>' \
--copyright-software 'Copyright Header' \
--copyright-software-description 'A utility to manipulate copyright headers on source code files' \
--copyright-year 2012-2017 \
--word-wrap 100 \
--output-dir /usr/src/
