Config::Model::Dpkg::Copyright - Fill the File sections of debian/copyright file
# this modules is used by cme when invoked with this command
$ cme update dpkg-copyright
This commands helps with the tedious task of maintening
"debian/copyright" file. When you package a new release of a
software, you can run "cme update dpkg-copyright" to update the
content of the copyright file.
This command scans current package directory to extract copyright and license
information and store them in the Files sections of debian/copyright file.
In debian package directory:
* run 'cme update dpkg-copyright' or 'cme update dpkg' * check the result with
your favorite VCS diff tool. (you do use
a VCS for your package files, do you ?)
Note: this command is experimental.
Results can be tweaked either by:
- Changing the list of files to scan or ignore. (By default,
licensecheck will decide which file to scan or not.)
- Specifying information for individual files
- Tweaking the copyright entries created by grouping and
The first 2 ways are described in "Selecting or ignoring files to
scan" in Dpkg::Copyright::Scanner and "Filling the blanks" in
The last way is described below:
Since the extraction of copyright information from source file is based on
comments, the result is sometimes lackluster. Your may specify instruction to
alter or set specific copyright entries in
"debian/fix.scanned.copyright" file (or
"debian/<source-package>.fix.scanned.copyright"). Each line of
this file will be handled by Config::Model::Loader to modify copyright
If the extracted copyright contains:
Copyright: 2014-2015, Adam Kennedy <firstname.lastname@example.org> "foobar
License: Artistic or GPL-1+
You may add this line in "debian/fix.copyright" file:
! Files:'*' Copyright=~s/\s*".*//
This way, the copyright information will be updated from the file content but
the extra ""foobar" will always be removed during updates.
Comments are accepted in Perl and C++ style from the beginning of the line.
Lines breaks are ignored.
Here's another more complex example:
// added a global license, MIT license text is filled by Config::Model
! copyright License:MIT
# don't forget '!' to go back to tree root
! copyright Files:"pan/general/map-vector.h" Copyright="2001,Andrei Alexandrescu"
# delete license text since short_name points to global MIT license
# use a loop there vvvvvv to clean up that vvvvvvvvvvvvvvvvvvvvvvv in all copyrights
! copyright Files:~/.*/ Copyright=~s/all\s*rights\s*reserved//i
# defeat spammer by replacing all '@' in emails of 3rdparty files
# the operation :~/^3party/ loops over all Files entries that match ^3rdparty
# and modify the copyright entry with a Perl substitution
! Files:~/^3rdparty/ Copyright=~s/@/(at)/
This section explains how cme merges the information from the existing
"debian/copyright" file (the "old" information) with the
information extracted by licensecheck
- The old and new information are compared in the form of
- New file entries are kept as is in the new list.
- When a file entry is found in both old and new lists, the
new X and license short names are checked. If they are unknown, the
information from the old list is copied in the new list.
- Old files entries not found in the new list are
- File entries are coalesced in the new list to reduce
redundancies (this mechanism is explained in this blog
- License entries are created, either attached to Files
specification or as global licenses. License text is added for known
license (actually known by Software::License)
- Directories (path ending with "/*") from old list
- Directory is found in the new list: the old information is
clobbered by new information.
- Directory not found in new list but exists: the old
information is copied in the new list.
- Directory is not found: the old information is
- Files entries are sorted and the new
"debian/copyright" is generated.
