TERMINOLOGY:

-- "slot" = A particular combination of case/number. Example slot names for nouns are "gen_s" (genitive singular) and "voc_p" (vocative plural). Each slot is filled with zero or more forms.

-- "form" = The declined form representing the value of a given slot.

-- "lemma" = The dictionary form. Generally the nominative masculine singular, but may occasionally be another form if the nominative masculine singular is missing. ]=]

-- Table mapping declension types to functions to decline the noun.

Most of the specifics of determining which stem to use -- and how to modify it for the given ending are handled in add_decl; the declension functions just need to generate -- the appropriate endings. local decls = {} -- Table specifying additional properties for declension types. Every declension type must have such a table, which -- specifies which category or categories to add and what annotation to show in the title bar of the declension table. -- -- * Only the `cat` property of this table is mandatory; there is also a `desc` property to specify the annotation, but --  this can be omitted and the annotation will then be computed from the `cat` property. The `cat` property is either --  a string, a list of strings or a function (of two arguments, `base` and `stems` as above) returning a string or --   list of strings. The string can contain the keywords GENDER to substitute the gender (and animacy for masculine --  nouns) and POS (to substitute the pluralized part of speech). The keyword GENPOS is equivalent to 'GENDER POS'. If --  no keyword is present, ' GENPOS' is added onto the end. If only GENDER is present, ' POS' is added onto the end. --  In all cases, the language name is added onto the beginning to form the full category name. -- * The `desc` property is of the same form as the `cat` property and specifies the annotation to display in the title --  bar (which may have the same format as the category minus the part of speech, or may be abbreviated). The value --  may not be a list of strings, as only one annotation is displayed. If omitted, it is derived from the category --  spec(s) by taking the last category (if more than one is given) and removing ' POS' before keyword substitution. local declprops = {}

--[=[ Propagate `property` (one of "animacy", "gender" or "number") from nouns to adjacent adjectives. We proceed as follows: 1. We assume the properties in question are already set on all nouns. This should happen in  set_defaults_and_check_bad_indicators. 2. We first propagate properties upwards and sideways. We recurse downwards from the top. When we encounter a multiword spec, we proceed left to right looking for a noun. When we find a noun, we fetch its property (recursing if the noun  is an alternant), and propagate it to any adjectives to its left, up to the next noun to the left. When we have processed the last noun, we also propagate its property value to any adjectives to the right (to handle e.g.  anděl strážný "guardian angel", where the adjective strážný should inherit the 'masculine' and 'animate'   properties of anděl). Finally, we set the property value for the multiword spec itself by combining all the non-nil properties of the individual elements. If all non-nil properties have the same value, the result is that value, otherwise it is `mixed_value` (which is "mixed" for animacy and gender, but "allthree" for number). 3. When we encounter an alternant spec in this process, we recursively process each alternant (which is a multiword  spec) using the previous step, and combine any non-nil properties we encounter the same way as for multiword specs. 4. The effect of steps 2 and 3 is to set the property of each alternant and multiword spec based on its children or its neighbors. ]=] local function propagate_properties(alternant_multiword_spec, property, default_propval, mixed_value) propagate_multiword_properties(alternant_multiword_spec, property, mixed_value, "nouns only") propagate_multiword_properties(alternant_multiword_spec, property, mixed_value, false) propagate_properties_downward(alternant_multiword_spec, property, default_propval) end
