NAME

elektra-merge-strategies - how to merge key sets
In elektra-tools a three way merging was implemented. It can also use be used for two way merging, e.g. for importing.
Note: For a two-way merge, the ours version of the keys is used in place of base

3-WAY

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.

STRATEGIES

Currently the following strategies exist:
preserve
Automerge only those keys where just one side deviates from base (default).
ours
Whenever a conflict exists, use our version.
theirs
Whenever a conflict exists, use their version.
cut
Removes existing keys below the resultpath and replaces them with the merged keyset.
import
Preserves existing keys in the resultpath if they do not exist in the merged keyset.
 
If the key does exist in the merged keyset, it will be overwritten.
 
(avoid using it)
