DESCRIPTION

       gbp dch reads git commit messages and generates  the  Debian  changelog  from  it.  If  no
       arguments  are given, gbp dch starts from the last tagged Debian package version up to the
       current tip of the  current  branch.  If  the  distribution  of  the  topmost  section  in
       debian/changelog  is UNRELEASED, the changelog entries will be inserted into this section.
       Otherwise, a new section will be created.

       If --auto is given gbp dch, tries to guess the last Git commit documented in the changelog
       -  this  only  works  in  snapshot mode. Otherwise, --since can be used to tell gbp dch at
       which point it should start in the Git history.

       The additional path arguments can be used to restrict the repository paths gbp  dch  looks
       at. Setting path to debian/ is a good choice if upstream uses Git and all Debian packaging
       changes  are  restricted  to  the  debian/  subdir.  In  more  sophisticated  cases  (like
       backports),  you  can  use  --git-log to restrict the generated changelog entries further,
       e.g. by using --git-log="--author=Foo Bar".

OPTIONS

       --version
              Print version of the program, i.e. version of the git-buildpackage suite

       -v

       --verbose
              Verbose execution

       -h

       --help Print help and exit

       --color=[auto|on|off]
              Whether to use colored output.

       --color-scheme=COLOR_SCHEME
              Colors to use in output (when color is enabled). The  format  for  COLOR_SCHEME  is
              '<debug>:<info>:<warning>:<error>'.  Numerical values and color names are accepted,
              empty fields imply the default color. For  example,  --git-color-scheme='cyan:34::'
              would  show  debug  messages  in  cyan, info messages in blue and other messages in
              default (i.e. warning and error messages in red).

       --debian-branch=branch_name
              The branch in the Git repository the Debian package is being developed on,  default
              is master.

       --upstream-branch=branch_name
              Branch to determine the upstream version from.  Default is upstream.

       --git-upstream-tag=TAG-FORMAT
              use  this  tag  format  when  looking  for  tags  of  upstream versions, default is
              upstream/%(version)s.

       --ignore-branch
              Don't check if the current branch matches debian-branch.

       --debian-tag=tag-format
              tag format used, when tagging debian versions, default is debian/%(version)s

       --since=committish
              Start reading commit messages at committish.

       --auto, -a
              Guess the last commit documented in the changelog from the snapshot banner (or from
              the last tag if no snapshot banner exists).

       --[no-]meta
              Parse meta tags like Closes:, Thanks: and Gbp-Dch:. See META TAGS below.

       --meta-closes=bug-close-tags
              What  meta tags to look for to generate bug-closing changelog entries.  The default
              is 'Closes|LP' to support Debian and Launchpad.

       --meta-closes-bugnum=bug-number-format
              What regular expression should be used to parse out the bug number.  The default is
              '(?:bug|issue)?\#?\s?\d+'.  Note: the regex should suppress all portions of the bug
              number that are not wanted using "(?:)", see Python regex manual for details.

              Example: --meta-closes-bugnum="(?:bug)?\s*ex-\d+" would match all of the following:

                               Possible Txt  Match?    Result
                               ------------  ------    ------
                               bug EX-12345    Y       EX-12345
                               ex-01273        Y       ex-01273
                               bug ex-1ab      Y       ex-1
                               EX--12345       N

       --[no-]full
              Include the full commit message in the changelog output.

       --snapshot, -S
              Create a snapshot release entry. This adds a snapshot release number and a  warning
              banner to the changelog entry. The release version number is being auto incremented
              with every new snapshot  release  to  avoid  packages  downgrades  during  snapshot
              testing.

       --snapshot-number=expression
              Python expression that gets eval()ed to the new snapshot number.

       --release, -R
              Remove  any  snapshot  release  banners  and  version  suffixes,  set  the  current
              distribution to unstable, and open the changelog for final tweaking.

       --new-version=version, -N version
              Add a new changelog section with version newversion. Together with --snapshot,  the
              snapshot number will be appended to newversion.

       --team Create a Team upload changelog entry.

       --bpo  Increment  the Debian release number for an upload to backports, and add a backport
              upload changelog comment.

       --nmu  Increment  the  Debian  release  number  for a non-maintainer upload.

       --qa   Increment the Debian release number for a Debian QA  Team  upload,  and  add  a  QA
              upload changelog comment.

       --distribution=name
              Set the distribution field to name.

       --force-distribution
              Force the distribution specified with --distribution to be used, even if it doesn't
              match the list of known distributions.

       --urgency=level
              Set the urgency field to level.

       --git-log=git-log-options
              Options passed on verbatim to git-log(1).

       --id-length=N
              Include N digits of the commit id in the changelog entry. Default is to not include
              any commit ids at all.

       --ignore-regex=regex
              Ignore commit lines matching regex when generating the changelog.

       --git-author
              Use user.name and user.email from git-config(1) for changelog trailer.

       --[no-]multimaint-merge
              Merge commits by maintainer.

       --spawn-editor=[always|snapshot|release]
              Whether to spawn an editor: always, when doing snapshots or when doing a release.

       --commit-msg=msg-format
              use  this  format  string  for  the  commit  message  when committing the generated
              changelog  file  (when  --commit  is  given).   Default  is  Update  changelog  for
              %(version)s release

       --commit
              Commit the generated changelog.

       --customizations=customization-file
              Load Python code from customization-file.  At the moment, the only useful thing the
              code can do is define a custom format_changelog_entry() function.

SNAPSHOT MODE

       Snapshot mode can be used for quick test and install cycles without having to worry  about
       version numbers or changelog entries.

       When  using  --snapshot  or  -S,  gbp  dch uses a pseudo header in the Debian changelog to
       remember the last git commit it added a changelog entry for. It also sets a version number
       ending  in  ~<snaspshotnumber>.gbp<commitid>.   It  automatically  increments the snapshot
       number on subsequent invocations of gbp dch -S so that later snapshots automatically  have
       a higher version number. To leave snapshot mode, invoke gbp dch with the --release option.
       This removes the pseudo header and unmangles the version number so  the  released  version
       has a higher version number than the snapshots.

META TAGS

       Additional  to the above options, the formatting of the commit message in debian/changelog
       can be modified by special tags (called Meta Tags) given in the git commit  message.  Meta
       Tag  processing  can  be activated via the --meta option. The tags must start at the first
       column of a commit message but can appear on any line.  They  are  of  the  form  Tagname:
       value. Valid Meta Tags are:

          Gbp-Dch: action
              Supported  actions  are:  Ignore  which  will  ignore  this  commit when generating
              debian/changelog, Short which will only use the description (the first line) of the
              commit  message  when generating the changelog entry (useful when --full is given),
              and Full which will use the full commit message when generating the changelog entry
              (useful when --full is not given).

              In addition to Gbp-Dch, the deprecated Git-Dch is still supported.

       Thanks: msg
              Add a thanks message after the commit message.

       Closes: bugnumber
              Indicate  in  the  debian/changelog that the bug was closed by this commit. See the
              --meta-closes on how to extend this for other bugtrackers.

       The following git commit message:

             Document meta tags

             so one doesn't have to consult the manual

             Gbp-Dch: Short
             Closes: #636088
             Thanks: Raphaël Hertzog for the suggestion

       Results in this debian/changelog entry:

             * Document meta tags.
