Add function isCorrectLastCharacter

[kumakyoo42]

This is a start on issue #3264.

I thought it might be a good idea to add this one already, although it is not used yet. I plan to add some more of such functions (checking the first symbol, checking all symbols of a sentence, checking some typical mistakes like space before comma and so on). Eventually they can be used to implement the real check.

I changed the function a little bit compared to the function given in the issue: It now returns the offending character instead of false. This might be useful in warning messages.

I'm unsure if the place I've choosen (Model/Table/SentenceTable) is a good place for these functions. If you prefere some other place, please just tell me.

Thank you 🙂

I would like to suggest moving the check method to src/Model/Entity/Sentence.php.

You could do something like

class Sentence extends Entity
{
    public function isCorrectLastCharacter() {
        $sentence = $this->sentence;
        $lang = $this->lang;
        // do your thing... 
    }
}

And then

class SentenceTest extends TestCase
{
    public function testIsCorrectLastCharacter() {
        $entity = new Sentence(['lang' => 'eng', 'text' => 'Test this']);

        $result = $entity->isCorrectLastCharacter();

        $this->assertFalse($result);
    }
}

And later we can make it a model validation rule like this.

I didn't understand that part about the model validation rule, but that can be kept for later...
