Builds stats data from a numstat entry

@param insertions_s [String] insertions field from numstat output

@param deletions_s [String] deletions field from numstat output

@param include_binary [Boolean] whether to include the ‘:binary` key

@return [Hash] stats hash with insertion and deletion totals

parse (output, include_dirstat: false)

# File lib/git/parsers/diff.rb, line 170
def parse(output, include_dirstat: false)
  lines = output.split("\n").reject(&:empty?)
  numstat_lines, shortstat_line, dirstat_lines = split_sections(lines, include_dirstat)

    shortstat: Diff.parse_shortstat(shortstat_line),
    dirstat: include_dirstat ? Diff.parse_dirstat(dirstat_lines) : nil
  )
end

Parse numstat output into DiffResult

@param output [String] raw numstat + shortstat output

@param include_dirstat [Boolean] whether dirstat output is expected

@return [Git::DiffResult]

parse_as_map (lines, include_binary: false)

# File lib/git/parsers/diff.rb, line 208
def parse_as_map(lines, include_binary: false)
  lines.to_h do |line|
    insertions_s, deletions_s, filename = line.split("\t", 3)

    dst_path, _src_path = parse_rename_path(filename)
    [Diff.unescape_path(dst_path), build_stats(insertions_s, deletions_s, include_binary)]
  end
end

Parse numstat lines into a path -> stats hash (for combining with other formats)

@param lines [Array<String>] numstat lines

@param include_binary [Boolean] whether to include binary flag

@return [Hash<String, Hash>] path to stats mapping (keyed by destination path)

      insertions: Diff.parse_stat_value(insertions_s),
      deletions: Diff.parse_stat_value(deletions_s)
    )
  end
end

Parse numstat lines into DiffFileNumstatInfo array

@param lines [Array<String>] numstat lines

@return [Array<Git::DiffFileNumstatInfo>]

  elsif (match = filename.match(RENAME_PATTERN))
    [match[2], match[1]]
  else
    [filename, nil]
  end
end

Parse potential rename path into [dst_path, src_path]

@param filename [String] the path string from numstat output

@return [Array(String, (String, nil))] [destination_path, source_path_or_nil]
