NAME

       kdb-merge - Three-way merge of KeySets

SYNOPSIS

       kdb merge [options] ourpath theirpath basepath resultpath

       ourpath
              Path to the keyset to serve as ours

       theirpath
              path to the keyset to serve as theirs

       basepath
              path to the base keyset

       resultpath
              path without keys where the merged keyset will be saved

DESCRIPTION

       Does a three-way merge between keysets.
       On success the resulting keyset will be saved to mergepath.
       On unresolved conflicts nothing will be changed.

THREE-WAY MERGE

       The kdb merge command uses a three-way merge by default.
       A  three-way merge is when three versions of a file (or in this case, KeySet) are compared
       in order to automatically merge the changes made to the KeySet over time.
       These three versions of the KeySet are:

       base   The base KeySet is the original version of the KeySet.

       ours   The ours KeySet represents the user´s current version of the KeySet.
              This KeySet differs from base for every key you changed.

       theirs The theirs KeySet usually represents the default version of a KeySet  (usually  the
              package maintainer´s version).
              This KeySet differs from base for every key someone has changed.

       The  three-way  merge works by comparing the ours KeySet and the theirs KeySet to the base
       KeySet. By looking for differences in these KeySets, a new KeySet called result is created
       that represents a merge of these KeySets.

CONFLICTS

       Conflicts occur when a Key has a different value in all three KeySets.
       Conflicts in a merge can be resolved using a strategy with the -s option. To interactively
       resolve conflicts, use the -i option.

OPTIONS

       •   -H, --help: Show the man page.

       •   -V, --version: Print version info.

       •   s, --strategy <name>: Specify which strategy should be used to resolve conflicts.

       •   -v, --verbose: Explain what is happening.

       •   -i, --interactive Interactively resolve the conflicts.

EXAMPLES

       To complete a simple merge of three KeySets:
       kdb merge user/ours user/theirs user/base user/result

       To complete a merge whilst using the ours version of the KeySet to resolve conflicts:
       kdb merge -s ours user/ours user/theirs user/base user/result

       To complete a three-way merge and overwrite all current keys in the resultpath:
       kdb merge -s cut user/ours user/theirs user/base user/result
