[Question] Can a plugin override core functions?

[rica-carv]

For instance, is it possible to alter the function toGlyph at a plugin basis?
Let's say i want to use another icon fonts besides Glyphicons or Fontawesome globally, even with another tag output instead the only two alowed (span & i).
e107::getParser()->toGlyph('fa-user-times','fw=1')
Therefore i would need to redefine this core function at plugin (or module) basis.

Is it possible to do it?

I think it is possible. Check e_parse.php addon files.

[lonalore]

No... I was wrong. It can be used only for extending toHtml() functionality.

@lonalore Maybe i've expressed myself wrong. I'm thinking of globally override a core function, to replace the original sitewide, not only in the plugin....

Yes and no. There is is no generic function to override core methods but there are many things implemented which allow for a huge amount of customization. There are addons (such as e_html, e_user, e_...) and also shortcodes provide plenty opportunities for customization. Each case is different, it would therefore be better to specify exactly what you'd like to change or do so we can give more specific advice. Sometimes there are already options available and no editing (or overriding) of core methods is required.

As for changing the toGlyph method, I don't think this is possible. What kind of icons do you have in mind? In general, such type of code (icons) use either the <span> or <i> tag.

EDIT: are you referring to SVG icons as discussed in #1958 ?

[rica-carv]

@Moc My ideia is to use the <svg> tag....
And yes, this question is somehow directly related to #1958...
But it can also be of some use for somebody to change any core class function....

Alright, then my answer above still stands :) I've updated it slightly.

Regarding the SVG icons, we'll continue that discussion in the other issue.
Closing this one.

Maybe another workaround for the toGlyph would be to template the toGlyph hardcoded html....
Just a thought....

Put that in the other issue haha 👍
