invoke editor

The following command must be run in a package source directory. When run, cme will load most files from "debian" directory and launch a graphical editor:

 cme edit dpkg

You can choose to edit only "debian/control" or "debian/copyright":

 cme edit dpkg-control
 cme edit dpkg-copyright

Or edit debian patches headers, all at once:

 cme edit dpkg-patches # note patches with 'es'

Or one patch at a time:

 cme edit dpkg-patch debian/patches/foo

Patch can be specified using the patch name:

 cme edit dpkg-patch foo

Just check dpkg files

You can also use cme to run sanity checks on the source files:

 cme check dpkg

Fix warnings

When run, cme may issue several warnings regarding the content of your file. You can choose to fix (most of) these warnings with the command:

 cme fix dpkg

check and arbitrary file

You can specify another file to check:

  cme check dpkg-copyright foobar

This applies only to "dpkg-control", "dpkg-copyright" or "dpkg-patch".

programmatic

This code snippet will change the maintainer address in control file:

 use Config::Model ;
 use Log::Log4perl qw(:easy) ;
 my $model = Config::Model -> new ( ) ;
 my $inst = $model->instance (root_class_name => 'Dpkg');
 $inst -> config_root ->load("control source Maintainer=foo@bedian.arg") ;
 $inst->write_back() ;

package dependency checks

Package dependencies are checked on several points:

• Whether the package is available in Debian (from sid to old-stable)
• If the package is a known virtual package. Known means listed in Debian packaging manual or known by the author. Feel free to log a bug against libconfig-model-dpkg-perl if a virtual package is missing. But please don't log a bug if the virtual package is used only during a transition.
• If a package older that the required version are available in Debian (from sid to old-stable). If not, cme will offer you the possibility to clean up the versioned dependency with "cme fix dpkg" command.
• The syntax of the dependency (including version requirement and arch specification).
• Consistency of alternate dependency for Perl libraries

These checks only generate warnings. Most of these checks can be fixed with "cme fix dpkg" command.

Migrate old package file

Most of old syntax can be automatically migrated to newer parameters with

  cme migrate dpkg

This migration can be limited to "control" or "copyright" files:

  cme migrate dpkg-control
  cme migrate dpkg-copyright

Restore GPL summary to default value:

  cme modify dpkg-copyright ~~ 'License:GPL text~'

Dump copyright file content in a format usable with "cme modify":

  $ cme dump dpkg-copyright
  Comment="Native package. This package is a spin-off from
  libconfig-model-perl. Upstream (who is also the debian packager)
  decided to create a Debian native package for the Debian specific
  parts of Config::Model"
  Files:"*"

modify a value with the command line:

 cme modify dpkg-copyright ~~ 'Comment="Modified with cme"'

Or apply more systematic changes. This example updates copyright years for all "Files" entries in "debian/copyright":

 cme modify dpkg-copyright ~~ 'Files:~/./ Copyright=~"s/2013/2014/"'

remove an uploader from control files

 cme modify dpkg control source Uploaders:-~/johndoe/

or

 cme modify dpkg-control ~~ source Uploaders:-~/dod/

If you want to remove a guy named Ian, you'll have to be a little more specific to avoid removing all debian developers:

 cme modify dpkg-control ~~ source Uploaders:-="Ian Smith<iansmith@debian.org>"

add a new uploader

The quotes are required otherwise bash will complain. These 2 commands give the same results:

 cme modify dpkg-control ~~ 'source Uploaders:<"John Doe<johndoe@foo.com>"'
 cme modify dpkg-control ~~ 'source Uploaders:.push("John Doe<johndoe@foo.com>")'

Add an uploader to a sorted list of Uploaders (yes, insort, with a 'o', not "insert" with a 'e'):

 cme modify dpkg-control ~~ 'source Uploaders:.insort("John Doe<johndoe@foo.com>")'

The above command make sense only if the list is sorted. Let's sort the list of uploaders:

 cme modify dpkg-control ~~ 'source Uploaders:@'
 cme modify dpkg-control ~~ 'source Uploaders:.sort'

The 2 commands can be combined:

 cme modify dpkg-control ~~ 'source Uploaders:.sort Uploaders:.insort("John Doe<johndoe@foo.com>")'

The "modify" command of cme uses the syntax defined by Config::Model::Loader. See "load string syntax" in Config::Model::Loader
