45 # These are only groups of constants, but should be treated like typedefs or enums. Each one represents a distinct type and
46 # their values should only be one of their constants or undef.
50 # Constants: MenuEntryType
52 # The types of entries that can appear in the menu.
54 # MENU_TITLE - The title of the menu.
55 # MENU_SUBTITLE - The sub-title of the menu.
56 # MENU_FILE - A source file, relative to the source directory.
57 # MENU_GROUP - A group.
58 # MENU_TEXT - Arbitrary text.
59 # MENU_LINK - A web link.
60 # MENU_FOOTER - Footer text.
61 # MENU_INDEX - An index.
62 # MENU_FORMAT - The version of Natural Docs the menu file was generated with.
63 # MENU_ENDOFORIGINAL - A dummy entry that marks where the original group content ends. This is used when automatically
64 # changing the groups so that the alphabetization or lack thereof can be detected without being
65 # affected by new entries tacked on to the end.
66 # MENU_DATA - Data not meant for user editing.
70 # <PreviousMenuState.nd> depends on these values all being able to fit into a UInt8, i.e. <= 255.

120 # split into subgroups.
121 # MENU_GROUP_UPDATEORDER - The group should be resorted.
123 # MENU_GROUP_HASENDOFORIGINAL - Whether the group contains a dummy <MENU_ENDOFORIGINAL> entry.

127 # MENU_GROUP_UNSORTED - The group's contents are not sorted.
