Hors #
Overview #
A simple Dart package to extract date and time from natural speech.
Currently works only with russian language.
Usage #
To use this package you need to create a Hors object with list of TokenParser and list
of Recognizer.
Out of the box there is rich collection of both types, see Recognizer.all and TokenParsers.all.
Base example looks like this:
import 'package:hors/hors.dart';

final hors = Hors(
recognizers: Recognizer.all,
tokenParsers: TokenParsers.all,
);

final result = hors.parse('Завтра состоится событие в 11 часов вечера');

parse method also has optional arguments:

DateTime fromDatetime – the date relative to which the intervals are to be measured.
int closestSteps – the maximum number of words between two dates at which will try to combine
these dates into one, if possible.

Limitations #

Some recognizers is relate with each-other, so you should know in which order they used or you can
get unpredictable results.

For now this library is backward compatible with the original one.
But this implementation written a little bit different.
