perl6-Lingua-EN-Conjugate

A Perl6 module that conjugates English verbs

Usage

 use Lingua::EN::Conjugate;

 my $verb = englishverb.new(bare => 'code', forms => <BeIng HaveEn>);
 for < I you he she it we you they > -> $s {
   for < p sp > -> $t {
     $verb.tense = $t;
     say $verb.conjugate( subject => $s );
   }
 }
 
 my @sentence = conjugate( bare => 'be', subject => 'it', interrogative => True );
 say @sentence ~ ' a function ?';

Object, Methods and details

Object englishverb must be created first with one only conmpulsory parameter

bare : String required, Bare form of the verb without the "to"

The object also accepts named parameters for method "conjugate at creation.

Method conjugate returns Array: accepts named parameters :

subject : String any of I , he , she , it , we , you , they , default self init
alias : Replace the subject in the ouput array , default self init
mod : String, any of will , shall , may , can , default self init
tense : String, any of p,sp ; "p" = Present, "sp" = Past , default self init
forms : Array of String, many of = BeIng BeEn HaveEn; BeIng=continuous, BeEn=Passive, HaveEn=Perfect , default self init
negation : Bool default False;
shortneg : Bool default False, use the short negation ( ex: [will not] => [won't] );
interrogative : Bool default False, Use interrogative form

Method is-irreg returns Bool, accepts string default self bare

Tells if passed verb is irregular

Function usage

Subroutine "conjugate" accepts named parameter "bare" and all named parameters of the object method
Subroutine "is-irreg" behaves the as object method

Purpose And Notes

Warning, this is not a direct port of the Perl5 "Lingua-EN-Conjugate" module !

Instead of using fixed tense blocks to conjugate an English verb, this module uses notions of "forms" which can be combined. IE: The "Past Perfect Continuous/Progressive" of a verb is in this case, The "Perfect" and "Continuous" forms conbined and evaluated with the "Past Tense"

The notions used by the module:

SUBJECT:

The sentence's actor, any of I he she it we you they

TENSE:

The grammatical time of the action. "Time" is a physical notion, "Tense" a grammatical one. English has only 2 "Tense": Past and Present; The "Future" tense is a modality. Two Tenses are aviable: p = Present, sp = Past

MODALITY:

Allows speakers to evaluate a proposition relative to a set of other propositions (Necessity or Possibility). The "future" (will) stands for a Possibility. Modality is any of will shall may can.

VERB:

Conveys an action (bring, read, walk, run, learn), or a state of being (be, exist, stand).

VERBAL FORM:

Way in which a verb is structured in relation to time, BE+ING = Continuity, non-finite. HAVE+EN: Past event linked to the present, BE+EN: Passive verbal form Modality can be many of HaveEn BeIng BeEn

Speculative Todo List

Short forms for: "I am" "will" "would" etc ...
"be able to"
"used to"
"ought to"
"Explain" method for educational purpose
Multi method with pure grammatical arguments ex: conjugate( tense => "Past Perfect Continuous" )
