public class VerbAgreementRule extends org.languagetool.rules.TextLevelRule
Simple agreement checker for German verbs and subject. Checks agreement in:
  • VER:1:SIN w/o ich: e.g. "Max bin da." (incorrect) [same for VER:2:SIN w/o du, VER:1:PLU w/o wir]
  • ich + VER:[123]:.* (not VER:1:SIN): e.g. "ich bist" (incorrect) [same for du, er, wir]
TODO:
  • wenn nur ein mögliches finites Verb -> das nehmen (Max machen das.)
  • Sie (i>1)
  • bei ich/du/er/wir sofort prüfen, damit alle vorkommen geprüft werden (Ich geht jetzt nach Hause und dort gehe ich sofort unter die Dusche.) [aber: isNear]
  • Alle Verbvorkommen merken (Er präsentieren wollte und Video hätte keine Pläne.)
