Development of Csound has now moved to version 7.0.  This means that
Csound 6 is now in maintenance mode.

Version 7.0 is in the develop branch and a new csound6 branch has
been created to produce 6.x updates to fix bugs until we release 7.0.

It builds and you can test it. There's a new parser in place already with several new possibilities.

We'll try to keep it building and running throughout development, although it may get broken from time to time.

Thanks for this, I intend to build and test as soon as I have some time.

I have two related questions/requests (I haven't kept up with all the
new features in Csound for some time, so please excuse me if I'm way off
here):

1. Is it/would it be possible for envelope opcodes (envelope and
lineexp) to accept an array of values as input? 

2. Is it/would it be possible to use an array as a p-field in the score?

Would those be viable requests for Csound7?

I don't see why this can't be done right now, it would be just another overload of an opcode. We can do it any time. For example, ftgen has one such overload. Provided the list of parameters is of the same type, we can create a version with an array.

> 2. Is it/would it be possible to use an array as a p-field in the score?

This is not possible because the numeric score is a completely separate element, has a different syntax etc. We would first need to think of what an array would be in the score, and introduce that. There are no big plans for the numeric score.

However, as in 1., the schedule etc opcode could be developed to have an array overload.

Yes, I can imagine that could be useful in some situations, but I assume
it wouldn't solve the issue. Or it would? I mean, you still couldn't
use an array as one (or more) of the p-fields within the array passed
to sched*, right?

On an indirectly related note: I assume that the limitation of no more
than one string per scoreline still holds, and that there are no plans
to change that, am I right?

Thanks for your attention.

That limitation was removed on 6.0 or even before. 

With schedule, I presume the idea would be that you have the following form

iArr[] fillarray 1,0,1,0dbfs,A4
schedule(iArr)

I don't see why this can't be done right now, it would be just
another overload of an opcode. We can do it any time.

That would be great, thanks!

2. Is it/would it be possible to use an array as a p-field in the

This is not possible because the numeric score is a completely
separate element, has a different syntax etc.

I see.

However, as in 1., the schedule etc opcode could be developed to have
an array overload.

Yes, I can imagine that could be useful in some situations, but I assume
it wouldn't solve the issue. Or it would? I mean, you still couldn't
use an array as one (or more) of the p-fields within the array passed
to sched*, right?

I created an opcode some time ago for this purpose:

https://csound-plugins.github.io/risset-docs/opcodes/ref.html

instr 1

  iArr[] fillarray 1, 1, 2, 3, 5, 8

  schedule 2, 1, -1, ref(iArr), "foo", "bar"

endin

instr 2

  iArr[] = deref(p4)

  Str1 = p5

  Str2 = p6

  printarray iArr

  prints "Str1: %s, Str2: %s\n", Str1, Str2
  turnoff

endin

schedule 1, 0, 10

It can be used to pass arrays by reference between instruments and opcodes (in the case of opcodes arrays are passed by value so this method is more efficient)

On an indirectly related note: I assume that the limitation of no more
than one string per scoreline still holds, and that there are no plans
to change that, am I right?

Thanks for your attention.

Really? That's great, I think the manual page should be updated
accordingly:

https://csound.com/docs/manual/ScoreStrings.html

Exactly, what I mean is that still you can't have an array in a p-field.

BTW, any pointers on how to convert a string with sub-strings separated
by a delimiter (for example, a coma) into an array of values?

In your previous example, how could I convert the string
"1,0,1,0dbfs,A4" into the array [1,0,1,0dbfs,A4]?

(Again, sorry if this is something I should know, but I've been out of
touch with Csound for some time..)

Yes, a long time ago. If it still says so in the
manual, it's been wrong for maybe ten years.

very much agreed.  this feature is perhaps the one which i miss most in 
daily work with csound.

The implementation would be much safer if the ARRAYDAT structure would gain some metadata regarding memory ownership, because this approach will fail if an array which was de-referenced from another is placed again at the left side of an operation which might cause reallocation. Such a change would even be backwards compatible, since at the moment it is always assumed that an array owns its memory. It would just make things safer for future implementations which can mark such wrong usages as errors.

Another use case for such a flag would be the possibility of accessing tables as if they were scalar arrays by creating an array as an alias to a table, or to create an array as a slice of another one (for example, to iterate over rows of a 2d array), as implemented here:

https://csound-plugins.github.io/risset-docs/opcodes/memview.html

That's a good idea. Something like that is planned to be part of the language now that the new parser is there.  This is much easier to maintain and extend.
