Library "Requires"

[Tyrulan]

When is it needed to add requires to your library?

I'm using it just to keep track of which libraries I'm referencing, but if I were to remove the "requires" labels it would still compile properly.

If a function inside library B needed to call a function inside library A we should let JassHelper know that A must be added before B. That's the reason the 'requires' keyword exists:

    library B requires A

        function Bfun takes nothing returns nothing
           call Afun()
        endfunction

    endlibrary

    library A

        function Afun takes nothing returns nothing
        endfunction

    endlibrary

That is strange to me, since my library has call to many other libraries for various tasks and don't need a "requires" header.

How the compiler orders libraries is partially arbitrary, so you could wind up being lucky and not having to put the requires keyword. Best to do it anyway though.

 

[Tyrulan]

Hm.. strange. Alright. Thanks!

without seeing your libraries in full it would be hard to tell if you are even doing anything that would make a library require another, anyway.

It's also used to catch up info from a library, Damage for example.

What?

What?

Like, you cant use Damage( By J4L ) without [ljass]requires[/ljass].
Cause that cathes up all functions from the System.

Great, CK, you're making up your own funny terms ._.
That's why he's confused xD

And you CAN use it..
If you don't use a library or you get really lucky and Damage is put really up high. =x

In other news, the awesome thing about libraries is you used to be able to make them require each other to bug JassHelper.
