--1 A Simple Spanish Resource Morphology
--
-- Aarne Ranta 2002 -- 2005
--
-- This resource morphology contains definitions needed in the resource
-- syntax. To build a lexicon, it is better to use $ParadigmsSpa$, which
-- gives a higher-level access to this module.

resource MorphoSpa = CommonRomance, ResSpa ** 
  open PhonoSpa, Prelude, Predef in {

  flags optimize=all ;


--2 Nouns
--
-- The following macro is useful for creating the forms of number-dependent
-- tables, such as common nouns.

oper
  numForms : (_,_ : Str) -> Number => Str = \vino, vini ->
    table {Sg => vino ; Pl => vini} ; 

-- For example:

  nomVino : Str -> Number => Str = \vino -> 
    numForms vino (vino + "s") ;

  nomPilar : Str -> Number => Str = \pilar -> 
    numForms pilar (pilar + "es") ;

  nomTram : Str -> Number => Str = \tram ->
    numForms tram tram ;

-- Common nouns are inflected in number and have an inherent gender.

  mkNoun : (Number => Str) -> Gender -> Noun = \mecmecs,gen -> 
    {s = mecmecs ; g = gen} ;

  mkNounIrreg : Str -> Str -> Gender -> Noun = \mec,mecs -> 
    mkNoun (numForms mec mecs) ;

  mkNomReg : Str -> Noun = \mec ->
    case last mec of {
      "o" | "e" => mkNoun (nomVino mec) Masc ; 
      "a" => mkNoun (nomVino mec) Fem ;
      "z" => mkNounIrreg mec (init mec + "ces") Fem ;
      _   => mkNoun (nomPilar mec) Masc
      } ;

--2 Adjectives
--
-- Adjectives are conveniently seen as gender-dependent nouns.
-- Here are some patterns. First one that describes the worst case.

  mkAdj : (_,_,_,_,_ : Str) -> Adj = \solo,sola,soli,sole,solamente ->
    {s = table {
       AF Masc n => numForms solo soli ! n ;
       AF Fem  n => numForms sola sole ! n ;
       AA        => solamente
       }
    } ;

-- Then the regular and invariant patterns.

  adjSolo : Str -> Adj = \solo -> 
    let 
      sol = Predef.tk 1 solo
    in
    mkAdj solo (sol + "a") (sol + "os") (sol + "as") (sol + "amente") ;

  adjUtil : Str -> Str -> Adj = \util,utiles -> 
    mkAdj util util utiles utiles (util + "mente") ;

  adjBlu : Str -> Adj = \blu -> 
    mkAdj blu blu blu blu blu ; --- 

  mkAdjReg : Str -> Adj = \solo -> 
    case last solo of {
      "o" => adjSolo solo ;
      "e" => adjUtil solo (solo + "s") ;
      _   => adjUtil solo (solo + "es")
----      _   => adjBlu solo
      } ;

--2 Personal pronouns
--
-- All the eight personal pronouns can be built by the following macro.
-- The use of "ne" as atonic genitive is debatable.
-- We follow the rule that the atonic nominative is empty.

  mkPronoun : (_,_,_,_,_,_,_,_ : Str) -> 
              Gender -> Number -> Person -> Pronoun =
    \il,le,lui,Lui,son,sa,ses,see,g,n,p ->
    {s = table {
       Ton Nom => il ;
       Ton x => prepCase x ++ Lui ;
       Aton Nom => strOpt il ; ---- [] ;
       Aton Acc => le ;
       Aton (CPrep P_a) => lui ;
       Aton q       => prepCase q ++ Lui ; ---- GF bug with c or p! 
       Poss {n = Sg ; g = Masc} => son ;
       Poss {n = Sg ; g = Fem}  => sa ;
       Poss {n = Pl ; g = Masc} => ses ;
       Poss {n = Pl ; g = Fem}  => see
       } ;
     a = {g = g ; n = n ; p = p} ;
     hasClit = True
    } ;


--2 Determiners
--
-- Determiners, traditionally called indefinite pronouns, are inflected
-- in gender and number, like adjectives.

  pronForms : Adj -> Gender -> Number -> Str = \tale,g,n -> tale.s ! AF g n ;

}
