Buffer symbols configuration

[wbercx]

Is there any way to configure which symbols are included in the Buffer Symbol search? I rely on this pretty heavily for file navigation.

What I've found is that it mainly picks up methods. In JS, if you have an object property with a function as a value (whether named or not), it is not considered to be a method and remains invisible to the symbols buffer. The same is true for class constants in PHP.

For example:

const x = {
    greetings() {
        // Gets detected
    }
    
    hello: function() {
        // Goes unnoticed
    }
    
    bye: function bye() {
        // Goes unnoticed
    }
}

<?php

class Something {
    const TEST = 'x'; // Goes unnoticed. Seems to be limited to class methods?
}
