#
attribute :name, String
# @return [String] the path to the file relative to the source tree
#
attribute :path, String
# @return [String] the directory to which the path is relative.
#
# @note The accepted values are:
# - `<absolute>` for absolute paths
# - `<group>` for paths relative to the group
# - `SOURCE_ROOT` for paths relative to the project
# - `DEVELOPER_DIR` for paths relative to the developer
# directory.
# - `BUILT_PRODUCTS_DIR` for paths relative to the build
# products directory.
# - `SDKROOT` for paths relative to the SDK directory.
#
attribute :source_tree, String, 'SOURCE_ROOT'
# @return [String] the file type (apparently) used for products
# generated by Xcode (i.e. applications, libraries).
#
attribute :explicit_file_type, String
# @return [String] the file type guessed by Xcode.
#
# @note This attribute is not present if there is an
# `explicit_file_type`.
#
attribute :last_known_file_type, String
# @return [String] whether this file should be indexed. It can
# be either `0` or `1`.
#
# @note Apparently present only for products generated by Xcode with
# a value of `0`.
#
attribute :include_in_index, String, '1'
# @return [String] a string containing a number which represents the
# encoding format of the file.

# highlighting.
#
# @example
# `xcode.lang.ruby`
#
attribute :xc_language_specification_identifier, String
# @return [String] a string that specifies the UTI for the structure of
# a plist file.
#
# @example
# `com.apple.xcode.plist.structure-definition.iphone.info-plist`
#
attribute :plist_structure_definition_identifier, String
# @return [String] Whether Xcode should use tabs for text alignment.
#
# @example
# `1`
#
attribute :uses_tabs, String
# @return [String] The width of the indent.
#
# @example
# `2`
#
attribute :indent_width, String
# @return [String] The width of the tabs.
#
# @example
# `2`
#
attribute :tab_width, String
# @return [String] Whether Xcode should wrap lines.
#
# @example
# `1`
#
attribute :wraps_lines, String
# @return [String] Apparently whether Xcode should add, if needed, a
# new line feed before saving the file.
#
# @example
# `0`
#
attribute :line_ending, String
# @return [String] Comments associated with this file.
#
# @note This is apparently no longer used by Xcode.
