dear csound6 developers -

do you plan to implement a simple assignment of arrays like
iArr[] = [1, 2, 3, 4, 5]
or
SArr[] = ["Csound", "6", "is", "great", "!"]
?

from my point of view (using csound for my work and teaching students) 
this would be very necessary. or speaking the other way round: if we 
cannot give the user a simple way to fill data in an array by typing a 
sequence of durations, pitches etc, we would loose half of the gain at 
least for people who are learning csound.

but you implemented so many things we wished before we spoke them out 
that perhaps this is also already there ...

thanks -

	joachim

hi victor, steven, john -

my i repeat the question below?

i hope my insistent question on this is not too nerve-racking. i'd just 
like to know whether this is on the to-do-list. or do you want me to 
file this as a feature request?

thanks -

At present the tabgen is the only initial value opcode.  I understand the
desire for iArr[] = [1, 2, 3, 4, 5] but I think this raises significant
parsing problems.  I had not forgotten this request.

We do have copying to a vector from a table, slicing and mapping over an
array.  Also array arithmetic -- unfinished but basically working.

thanks, john. good to know that it is on your list. i think, it is not 
important that this this feature is assigned to the '=' operator. 
something like
iArr[] fill [1, 2, 3, 4, 5]
or whatever would be fine, too, in my opinion, if it avoids parsing 
problems.

Hi John,

I think we might be able to parse the static initializer as an
expression, then map to an array_static_init opcode that's overloaded
with different var-arg types (all S, all k- and below, all a-). I
guess it depends if it'll clash with the array accessors. I'll try out
a quick test now to see if it'll cause an ambiguity or not.

Clearly a syntax of

kA[] tabfill 1,2,3,4,5,6,7,6,5,4,3,2,1

is "easy".  No parsing problems in that format. steven, let me know how
the experiments go

Hi John,

I gave it a shot but things didn't work out so well.  Things certainly
got ambiguous.  I used a rule like this:

staticArrayInit : '[' exprlist ']' { $$ = make_node(csound, LINE,
LOCN, T_ARRAY_INIT, NULL, $2); }

but that caused issues when using this in a csd:

SArr[] = [ "Test", "test2", "test 3"]

I think the array initializer rule is correct, and that the problem
might lie with the rest of the grammar.  One of the things I had been
thinking about lately is that with the semantic analyzer in place,
there may be a way to simplify the grammar further, but I'm unsure of
this.

I'm at a stopping point for now.  I'll move on to other work for the
day but will continue to think about this one. It could be that the
way I had done array identifiers and array expressions could be redone
too.

Thanks!
steven

OK; I have committed a fill opcode to initialise a 1-d k-array.
Not done it for strings yet -- will consider adding that
