keyword for "this struct"

04-03-2009, 08:24 PM

Err I need this for... err, well it would be nice to have, but I need to think of a good keyword for it.

Let's say the keyword was bubba

JASS:


struct xxxx
     method orz takes nothing returns bubba
     endmethod

     method aaa takes bubba A, bubba B, bubba C returns nothing
     endmethod

    static bubba array meh

endstruct

Equivalent to:

JASS:


struct xxxx
     method orz takes nothing returns bubba
     endmethod

     method aaa takes xxxx A, xxxx B, xxxx C returns nothing
     endmethod

    static xxxx array meh

endstruct

Guess the idea is understood.

PurplePoot	You could always just use this? More keywords tends to get annoying after a point.

Vexorian	The this keyword is already in use by jasshelper, giving two absurdly different actions to the same keyword is probably worse than having more keywords...

PurplePoot	self? I'm drawing blanks otherwise.

moyack	waht about me?? JASS: struct xxxx method orz takes nothing returns me endmethod method aaa takes me A, me B, me C returns nothing endmethod static me array meh endstruct

peq	I think this is only useful if you want to rename the struct which I think is a job for texteditors and not for tools like jasshelper. But if you want it use something like "thistype" or "mytype".

TEC_Ghost	I vote use "that"

akolyt0r	yeah ..i think this feature is totally unneeded ... some simple search/replace achieves the same..

Nah, it is useful for something else.

moyack	it makes the code more readable and faster to write, and this is always valuable.

The keyword should be thistype.

Right now I have to use textmacro constructors in many of my systems, since that's the only way to insert "this struct" and make sure it is treated as the child type (with appropriate default values set) during the constructor. I am assuming this is going to work with constructors, for example:

JASS:

interface Test
    real x = 0.
    real y = 0.
endinterface

struct Parent extends Test

    static method create takes unit u returns thistype
        local thistype p = thistype.allocate()
            call SetUnitX(u, p.x)
            call SetUnitY(u, p.y)
        return p
    endmethod

endstruct

struct Child extends Parent
    real x = 100.
    real y = 200.
endstruct

function SomeFunc takes unit u returns nothing
    call Child.create(u)
endmethod

Without thistype or a textmacro copy of the constructor for the child struct, the unit would be moved to 0, 0 instead of 100, 200. This is a major problem for certain types of systems, so this is useful for way more than search and replace.

Vexorian	textmacros (well, something like that) are the main reason behind this

grim001	OK, but will it work with constructors as per the example? Clarification: No, there will be a different way to solve the above problem, and this is intended for something else

Vexorian	Yes, that's right I turned it into a poll

Viikuna-	I missvoted "me", but I really think that "thistype" is the best.
