Имя (Name)

dpkg-mergechangelogs - 3-way merge of debian/changelog files

---

Синопсис (Synopsis)

dpkg-mergechangelogs [option...] old new-a new-b [out]

---

Описание (Description)

This program will use the 3 provided versions of the Debian
       changelog to generate a merged changelog file. The resulting
       changelog is stored in the file out or output to the standard
       output if that parameter is not given.

       Each entry is identified by its version number and they are
       assumed to be not conflicting, they are simply merged in the
       right order (by decreasing version number). When
       --merge-prereleases is used, the part of the version number after
       the last tilde is dropped so that 1.0-1~exp1 and 1.0-1~exp5 are
       considered to be the same entry. When the same version is
       available in both new-a and new-b, a standard line-based 3-way
       merge is attempted (provided that the module Algorithm::Merge is
       available — it's part of the package libalgorithm-merge-perl —
       otherwise you get a global conflict on the content of the entry).

Параметры (Options)

-m, --merge-prereleases
              Drop the part after the last tilde in the version number
              when doing version comparison to identify if two entries
              are supposed to be the same or not.

              This is useful when you keep using the same changelog
              entry but you increase its version number regularly. For
              instance, you might have 2.3-1~exp1, 2.3-1~exp2, ... until
              the official release 2.3-1 and they are all the same
              changelog entry that has evolved over time.

       --help Show the usage message and exit.

       --version
              Show the version and exit.

Окружение (Environment)

DPKG_COLORS
              Sets the color mode (since dpkg 1.18.5).  The currently
              accepted values are: auto (default), always and never.

       DPKG_NLS
              If set, it will be used to decide whether to activate
              Native Language Support, also known as
              internationalization (or i18n) support (since dpkg
              1.19.0).  The accepted values are: 0 and 1 (default).

---

Ограничения (Limitations)

Anything that is not parsed by Dpkg::Changelog is lost during the
       merge.  This might include stuff like comments which were not
       supposed to be there, etc.

INTEGRATION WITH GIT

If you want to use this program to merge Debian changelog files
       in a git repository, you have first to register a new merge
       driver in .git/config or ~/.gitconfig:

        [merge "dpkg-mergechangelogs"]
            name = debian/changelog merge driver
            driver = dpkg-mergechangelogs -m %O %A %B %A

       Then you have to setup the merge attribute for the
       debian/changelog file either in .gitattributes in the repository
       itself, or in .git/info/attributes:

        debian/changelog merge=dpkg-mergechangelogs
