I was thinking about refs too and I kinda doubt that just moving the refs in
memory works. Sequtils usually uses `shallowCopy()` for manipulation of
elements in the seq. Which imho avoids (deep) copying a string or seq inside
the seq and copies the "pointer" (reference). I guess OP shift() proc
@OderWat: do you mean something like this?
proc shift[T](a: var openarray[T]; d: int) =
if d == 0: discard # do nothing
elif abs(d) >= a.len: # reset all
zeroMem(addr a[0], a.len*sizeof(T))
elif d > 0: # right shift
moveMem(addr a[d], addr a[0], (a.le

Hi Simon, can you share how you managed to get GTK3 working on Windows 7?
I am trying to quote from your earlier response but I have finding difficult.
@OderWat
Sorry, can not really understand... Somethink like memCopy or memMove? That was
my first idea, but I was very unsure what would happen when array elements are
not somethink like plain ints, but objects with refs. Would that confuse the GC?
And of course one may ask if array shifting is
Would "shifting" a seq or even an array not just be one operation operation for
all elements at once and then initialisation of the remaining fields with 0
because an array/seq has continuous memory layout and the default init is
"zeroing memory" afaik.
Yes, for some languages shift may mean returning an element. But in Nim we have
shl and shr operators. scroll may be confused with rotation?
I will look at your code in more detail tonigth -- you are using magic reset
proc from system module. I tried also a year ago, then I asked Araq in IRC

I am not using Windows. For gentoo linux, command is just "emerge -av gnome". I
can search for directory paths, but I guess that will not really help you for
Windows.
Personally I would be very interested how well GTK3
Nice, though I'm used to shift meaning "remove the first value of the
(resizable) array and return the value", I think your proc feels more like it's
"scrolling" the array?
Anyway, naming aside, what do you think of this version?
proc scroll[T](a: var openarray[T]; d: int) =
It is about installing the development libraries themselves. I am doing a test
installation using the guide here

to see if I can get an GTK 3 project working and if I succeeds I will see if
