"Double-deref" not working in Keysharp.

[Winter Laite]

ISSUE

Variables as described on dynamic variables docs page do not function as in AHK.

working ahk script

target := 42
second := "target"
MsgBox(second)   ; Normal (single) variable reference => target
MsgBox(%second%)  ; Double-deref => 42

With AHK the MsgBoxes display as per the comments. With Keysharp both display “target”.

It appears that I attempted to implement this, but misunderstood the documentation. After revisiting the documentation, tell me if this is correct:

Scenario 1: what you listed above, where the variable is referenced by itself, and thus dereferences two levels deep: second => “target”, then target => 42

Scenario 2: the variable is used in conjunction with another value, to access a variable or property of an object, and thus dereferences only one level deep: %A_Index% => 1, 2 or 3, then concatenated with MyArray

MyArray1 := "A"
MyArray2 := "B"
MyArray3 := "C"
Loop 3
    MsgBox MyArray%A_Index%  ; Shows A, then B, then C.

‌

class myclass
{
  mymember1 := 123
}

c := new myclass()
val := 1
MsgBox(c.mymember%val%) ; Shows 123

\%val% => 1, then concatenated with mymember

‌

So by itself, it goes two levels deep, but when being used as a member and/or with a partial variable name, it goes one level deep.

[Winter Laite]

class myclass
{
  mymember1 := 123
}

c := myclass()
val := 1
MsgBox(c.mymember%val%) ; Shows 123

(Using the ‘new’ keyword here will throw on error)

I believe your explanation is right. You might consider this also:

MyArray1 := "A"
MyArray2 := "B"
MyArray3 := "C"
MyArray4 := MyArray1
;MyArray4 := %MyArray1% ; ERROR: Variable not found. Specifically: A
Loop 4
    MsgBox MyArray%A_Index%  ; Shows A, then B, then C, then A

Sounds good. The first snippet was just pseudo code to illustrate the point. Sounds like we agree so I’ll get going on it.

I’ve committed a fix, as well as updated unit tests. Please test.

All unit tests confirmed, also when modified to v2-like syntax. Marking resolved and closing. Excellent work, thank you!
