Support short class name for class auto-completion

[theofidry]

When using the default PsySH shell (v0.7), if I try the tab auto-completion when having typed "R", I will get:

• RuntimeException
• RangeException
• RecursiveIteratorIterator

But if I have a service Dummy/Run, it won't appear... I guess it's because the classname matcher doesn't account for the class short names. It would be great if their could be a support for it!

Cheers

I naively tried to change https://github.com/bobthecow/psysh/blob/master/src/Psy/TabCompletion/Matcher/ClassNamesMatcher.php#L45 for including short class names as well:

array_filter(
                get_declared_classes(),
                function ($className) use ($quotedClass) {
                    $shortClassName = substr($className, strrpos($className, '\\') + 1);

                    $classNameMatch = AbstractMatcher::startsWith($quotedClass, $className);
                    $shortClassNameMatch = AbstractMatcher::startsWith($quotedClass, $shortClassName);

                    return $classNameMatch || $shortClassNameMatch;
                }
            )

But somehow psysh just becomes unresponsive after that :/

Unfortunately this isn't possible, due to limitations in readline. It strips out completions that don't match the current input, so even if we provide Dummy\Run as a completion for Ru, readline would refuse to show it :(
