Method: Rugged::Index#merge_file

Defined in:
ext/rugged/rugged_index.c

#merge_file(path[, options]) ⇒ nil #merge_file(path) ⇒ nil

Return merge_file (in memory) from the ancestor, our side and their side of the conflict at path.

If :ancestor, :ours or :theirs is nil, that indicates that path did not exist in the respective tree.

Returns nil if no conflict is present at path.

The following options can be passed in the options Hash:

:ancestor_label

The name of the ancestor branch used to decorate conflict markers.

:our_label

The name of our branch used to decorate conflict markers.

:their_label

The name of their branch used to decorate conflict markers.

:favor

Specifies how and if conflicts are auto-resolved by favoring a specific file output. Can be one of ‘:normal`, `:ours`, `:theirs` or `:union`. Defaults to `:normal`.

:style

Specifies the type of merge file to produce. Can be one of ‘:standard`, `:diff3`. Defaults to `:standard`

:simplify

If true, the merge file is simplified by condensing non-alphanumeric regions.

Overloads:

  • #merge_file(path[, options]) ⇒ nil

    Returns:

    • (nil)
  • #merge_file(path) ⇒ nil

    Returns:

    • (nil)
