Subject: [Haskell-beginners] Clocks, scheduling, jack and
supercollider
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-15
Hello all,
I just installed the haskell-supercollider bindings ("hsc3") and I am able to
send events to supercollider and hear
sound. But I have no idea how to schedule events to be sent in the future - a
prerequisite to play a song.
Ideally I would sync to an external clock source, like a time code
(SMPTE/MIDI). Also it would be nice to listen to
jack-transport, so I can fast-forward and rewind from another application. But
the jack bindings for Haskell do not
mention jack-transport.
Do you have any advice where I should look next.

You might have more luck sending this question to the haskell-art mailing list:
http://lurk.org/groups/haskell-art/
though I certainly don't intend to discourage such questions here. If
someone here can answer it, so much the better!

The function is an internal back-end detail, not one the program calls
directly. So
renaming it would mean changing the caller, etc.

OK, use sandbox and "add-source".
But does that address the smart "make" concept? That is, will it automatically
rebuild
the gloss package if a file in it changed, when I compile the program that
imports it?

[ ? , translate (-50) 0 $ color green $ Circle 50 , ?]
The parens around -50 are necessary.
Is there a more elegant way to write it?
Without the parens, I don't understand what the compiler sees it as, based on
the error
message. How does the compiler parse it in that case?
Also, is the comma in a list different from the operator comma which is noted
as
right-associative precedence 5? I had thought that the item separator in the
list was
special syntax that had very low precedence. After all, I can write f$g as a
list item
without parens, and $ is lower than comma.
What is comma (as an operator) used for?

It most likely sees it as the binary minus rather than the unary minus.

The results point out the fragility of programmer expertise: advanced
programmers have strong expectations about what programs should look like,
and when those expectations are violated--in seemingly innocuous
ways--their performance drops drastically.

Without the parens, minus would be parsed just like plus.
What would 'translate +50 0 blah' parse into?

The _colon_ is a non-rebindable special-syntax operator with infixr 5.
Otoh, the _comma_ in a list is _not_ an operator but merely an item
separator.
Comma-separated list notation e.g. [1,2,3] is special syntax that desugars
to e.g. 1:2:3:[].
Other than that, the colon and comma don't have anything else in common.
