# Return a copy of the +options+ hash containing only keys that can be
# passed to Rugged. Allowed options are:
#
- # :max_size ::
- # An integer specifying the maximum byte size of a file before a it
- # will be treated as binary. The default value is 512MB.
- #
- # :context_lines ::
- # The number of unchanged lines that define the boundary of a hunk
- # (and to display before and after the actual changes). The default is
- # 3.
- #
- # :interhunk_lines ::
- # The maximum number of unchanged lines between hunk boundaries before
- # the hunks will be merged into a one. The default is 0.
- #
- # :old_prefix ::
- # The virtual "directory" to prefix to old filenames in hunk headers.
- # The default is "a".
- #
- # :new_prefix ::
- # The virtual "directory" to prefix to new filenames in hunk headers.
- # The default is "b".
- #
- # :reverse ::
- # If true, the sides of the diff will be reversed.
- #
- # :force_text ::
- # If true, all files will be treated as text, disabling binary
- # attributes & detection.
- #
- # :ignore_whitespace ::
- # If true, all whitespace will be ignored.
- #
# :ignore_whitespace_change ::
# If true, changes in amount of whitespace will be ignored.
#
- # :ignore_whitespace_eol ::
- # If true, whitespace at end of line will be ignored.
- #
- # :ignore_submodules ::
- # if true, submodules will be excluded from the diff completely.
- #
- # :patience ::
- # If true, the "patience diff" algorithm will be used (currenlty
- # unimplemented).
- #
- # :include_ignored ::
- # If true, ignored files will be included in the diff.
- #
- # :include_untracked ::
- # If true, untracked files will be included in the diff.
- #
- # :include_unmodified ::
- # If true, unmodified files will be included in the diff.
- #
- # :recurse_untracked_dirs ::
- # Even if +:include_untracked+ is true, untracked directories will
- # only be marked with a single entry in the diff. If this flag is set
- # to true, all files under ignored directories will be included in the
- # diff, too.
- #
# :disable_pathspec_match ::
# If true, the given +*paths+ will be applied as exact matches,
# instead of as fnmatch patterns.
#
- # :deltas_are_icase ::
- # If true, filename comparisons will be made with case-insensitivity.
- #
- # :include_untracked_content ::
- # if true, untracked content will be contained in the the diff patch
- # text.
- #
- # :skip_binary_check ::
- # If true, diff deltas will be generated without spending time on
- # binary detection. This is useful to improve performance in cases
- # where the actual file content difference is not needed.
- #
- # :include_typechange ::
- # If true, type changes for files will not be interpreted as deletion
- # of the "old file" and addition of the "new file", but will generate
- # typechange records.
- #
- # :include_typechange_trees ::
- # Even if +:include_typechange+ is true, blob -> tree changes will
- # still usually be handled as a deletion of the blob. If this flag is
- # set to true, blob -> tree changes will be marked as typechanges.
- #
- # :ignore_filemode ::
- # If true, file mode changes will be ignored.
- #
- # :recurse_ignored_dirs ::
- # Even if +:include_ignored+ is true, ignored directories will only be
- # marked with a single entry in the diff. If this flag is set to true,
- # all files under ignored directories will be included in the diff,
- # too.
