AddElement(List()) = "Value"

[Joakim Christiansen]

Able to write:

Code: Select all

AddElement(List()) = "Value"

Instead of:

Code: Select all

AddElement(List())
List() = "Value"

Would be handy for LinkedLists without a structure, but nothing important it's just nice syntax.

Try this:

Code: Select all

Macro AddElementAssign(list)
  AddElement(list) : list 
EndMacro

NewList l1.l()
NewList s1.s()

AddElementAssign(l1()) = 123
Debug l1()

AddElementAssign(s1()) = "Hello1"
Debug s1()

If AddElementAssign(s1()) = "Hello2"
Else
  Debug "Out of memory"
EndIf
Debug s1()

I don't think this will be implemented, AddElement() is a function that
returns a pointer, so the compiler had to deside for assignment or pointer returning,
that would make compiling more complicated than necessary.

additionally, a LinkedList often is used for structured elements.
it is impossible to assign a complex structure with "="

[blueznl]

I'd be tempted to request something like this:

Code: Select all

Structure x
  a.l
  b.l
EndStructure

z.x
z = 1,2

 :)

blueznl: It's kinda nice.

AddElement(StructuredList())\Member = Value

[Kaeru Gaman]

this is one element of a complex structure, not the structure itself... :roll:

[Trond]

So what? It's not needed to set the entire structure. You can't do that even without the AddElement().

[Demivec]

You could use curly braces as delimeters for a structured set.

Code: Select all

Structure x
a.l
b.l
c.s
d.d
EndStructure

z.x
z = {1,2,"three",4.5}
z = {,,"three"}  ;to set just the third element
;or
NewList y.x()
AddElementAssign(y(),{,z\a,"three"})

Curly's are a bit harder to see though and this would get crazier with arrays and unions and such.

that's what I said more than once.
an AddElementX() = bla is useless, since you can never use it for structured elements.
and I would say, 99% of LinkedLists are structured.
in fact, I see no use in a List without a structure.

[Trond]

Then Variable = Value is useless also, since you can't use it for structures?

[Kaeru Gaman]

*sigh* what is you problem?

1. a complex structure cannot be filled with "="
2. the main use of LinkedLists is to use structured Lists.
=> an AddElement() = value is almost always useless.

that is my point, nothing less, nothing more.

[Trond]

Why is it almost useless? It saves 1 line. Which is exactly the same number of lines that's saved for unstructured lists. So it's just as useful. It will also save more lines in case you do not need to initialize all the structure members.
