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" )
