RunRev and music

[René Micout]

Hello everybody,
I have a project : make a bridge between RunRev and Macintosh Core Audio/Core 
Midi with AppleScript and if successful do benefit the community...
I am searching books, tutorials or “something” (in english or in french [is it 
possible to dream ?]) witch talk about working Macintosh Core audio/Core Midi 
with AppleScript.
Somebody know that ?
Thank you

Re: valentina, externals of libdatabase

[Bernard Devlin]

Thanks Trevor.  I expect to be on my own with LibDatabase now.  I can
understand your focus is on Sql Yoga right now.

I will have a look at the externals lesson.

FYI LibDatabase does kind of work with Valentina 4.  But when an array
is returned with a result set, there are no column names.

There is another weird problem with quotation marks.  I'm using Rev on
Vista at the moment.  I see from the zip file containing LibDatabase
that it was prepared on OS X.  LibDatabase relies on multi-item array
names, where some of the items are quoted.  That causes a problem
within LibDatabase when it looks for values by key within arrays.

The quotation marks do not register any problem in the Script Editor.
But they are not the same charToNum on windows i.e. on Windows quote
is something like 34, whereas the quotation marks in the arrray names
are something like char 143 (I don't have Rev installed on this
machine).  So, I think there is a macToISo issue in Rev itself.  I
understand it is supposed to be applied automatically to stacks when
Rev opens.  I seem to have come across an issue like this a couple of
years ago.

I may try to get round this quotation character issue and see if that
fixes the lack of column names (maybe there is some magic going on in
LibDatabase when it looks for Valentina column names).

May be there is sense to use just Valentina API?

Re: Applescrript from Rev

on mac OS X(leopard)
I'd like do send an applescript from rev to mail.app
it should be something like this :
open mail.app
open a new message
fill the fields "To", "Object" and "Message" with variables



Here is the script I use:

Here is the Rev part, fill in the recipVar, subjectVar and bodyVar
variables as required:

   put the cMakeEmail of this stack into makeEmail
   replace "*addr*" with quote & recipVar & quote in makeEmail
   replace "*subj*" with quote & subjectVar & quote in makeEmail
   replace "*body*" with quote & bodyVar & quote in makeEmail
   do makeEmail as AppleScript

And here is the AppleScript that I store in a custom property of the
stack, called cMakeEmail:

tell application "Mail"
activate
copy *addr* to recipVar
copy *subj* to subjVar
copy *body* to bodyVar

set newMessage to make new outgoing message with properties
{subject:subjVar, content:bodyVar & return & return}
tell newMessage
set visible to true
make new to recipient at end of to recipients with properties
{address:recipVar}
end tell
end tell

This is a very basic AppleScript that just assumes a single recipient
and no attachments, but it should be enough to get you started anyway.
If the body of the email contains any quotes, you need to escape them,
or replace them with single quotes first.

Sarah

Re : Crappy Website

[Francis Nugent Dixon]

Richmond,

I have a liitle test for you !

Take a look at your desktop. If it is full of little alias
icons, and you spend a few seconds trying to find the right
one when you want to launch an application, then you can stop
reading now. I now know why your sister finds that your site
is like a dogs dinner.

Now - a second test. Get yourself a pack of different coloured
Post-Its, from your local store. You also need a wall .. !

Build yourself a heirarchy of your site on the wall. Each Site
Level is a Post-It MENU, and all the items under each menu
represent either another level of menu, or a HTML page. If you
appear to have too many items in your menu, open another
menu level, but try not to have too many. Always ask the questions :
Is this the right place for this item, or more correctly, all all
the items in this menu siblings ?

I agree with Sarah that you should take a look at those CSS
templates, but I think it unfortunate that we can't see any
drop-down menus there. Using drop-down menus gives you more scope.
And all the menus I see, imply a two level heirarchy only. In
fact, all the templates are the same design, only the colours change.
They all look very nice, but in fact they are forcing you into a
strait-jacket.

Play with your diagram on your wall for a few days.  Sit down
in front of it and contemplate it (use the colours for different
types of function). Think carefully before you assign a Menu
Title, or a Menu Item (Short and Sweet names do the trick).
Extension of your site at a later date should be a piece of cake.

Finally, spend some time on designing a nice background for your
site pages, and use it on every page. It will save you much time.

Your site users should be able to intuitively wander your site.. !
(Oh !! - Don't forget a "Back to Main Menu" menu   : >)

-Francis

It is an expression used by developpers.

If a feature is not automatic or is not provided by the developpment
tool, thus developpers have to develop it manually or by hand.
But don't worry, developpers also use their hands when they script;)

Although if they're bad developers we can say they have developed with
their feet.
An expression of mine to qualify a very bad code: "This is developed
with feet. Unfortunately, they forgot to remove their shoes"...

Re: (Data Grid) How to get the setting of the dgHeaderAlignment["column"] saved

I save the stack

What am I missing?


It's a bug. The Data Grid isn't setting alignment when creating the  
headers from scratch.


You can either set the alignment each time your program opens or add  
a 1 line fix to the Data Grid behavior script. Instructions follow.


Thanks Trevor for your answer and the precisely explained procedure to  
add the line to the _tableCreateHeaders command.


But, when I do so, I get a new issue : after quitting Rev, when I  
launch my stack again, the headers of the columns, not only are not  
centered anymore but also some of them are even so shifted to the  
left, that  one can't see the first characters of them; bizarre ;-)


More precisely : could be useful to say that the data grid is on a  
substack;

Even without quitting Rev :
- if I close the substack and re-open it the headers keeps centered
- If I close the substack AND its main stack, then, when I re-open  
them, I get the headers shifted to the left.


Not a big problem anyway (I can set the alignment each time a card  
opens as you suggest); but I am curious about what is happening ;-))


It was the first time I had a look at your scripts in the  
revdatagridlibrary; very impressive; "chapeau bas" ;-))

Hi Ruslan,

I am indeed considering just using the Valentina API.  I started using
LibDatabase as I'd remembered it was fairly straightforward in the
past - it makes clever use of Rev arrays, getting out of one's way as
an abstraction layer.  I saw from looking through the Rev list in the
past that people had been using it, and that using the SQL with
Valentina had often been recommended as the way to get started with
Valentina.

I'm thinking about the best way to use the Valentina API that would be
smoothest whilst working with Rev.

One of the great things about Rev is that if the IDE can do it you can

or just in one style like "Mozart's Musical Dice Game for
Composing a Minuet"?

Automatic music generator are really useful to add
infinite variety to stacks that require constant use.
René, Have you created similar automatic music generator
with Runrev?

Re: RunRev and music

[René Micout]

Alejandro,
Thank you for answer.
Yes I know UDI's work. It is about Midi File Format (that is a part of my 
work)...
But my new research is about direct access to Core Audio / Core Midi (in real 
time...)
Exagofon my application is not a sequencer like Logic or ProTools, it is very 
much easy to play with, it is like a game for a child (my small-son — yes I am 
a grand-father ! — play with it and he is 4) but it is powerful and old many 
possibilities.
For my own (pour ma part) my musical projects turn around contemporary music 
like american minimalists (John Cage, Morton Felman, Terry Riley, la Monte 
Young, Steve Reich, Philip Glass, etc...) and rock few special like Soft 
Machine, Fripp & Eno, Robert Wyatt. But there is no exclusive, all is open...
If you have not already, watch part 6 of the presentation of Exagofon towards 
the end, there are some more interesting musical examples than the beginning 
(witch is more didactic) ; it is not really "compositions", but...

http://www.youtube.com/watch?v=YgdRplS1wZE

I wish you also a good (half) week-end.

PostgreSQL/On-Rev Database Tables

[Rick Harrison]

Hi there,

I created PostgreSQL database on On-Rev
using the PostgreSQL Database Wizard which seemed
to work fine. 

Then I was trying to use phpPgAdmin to create tables
for the database. It told me that I couldn't do it because 
I wasn't a "SuperUser" which to me seemed crazy because 
I was logged in as the user who created the database in the first place.

Does anyone have any ideas or has anyone ever done this
successfully on On-Rev?

I've also noticed that documentation on how to do these
things is lacking. Suggestions?

Thanks in advance,

Rick

Re: PostgreSQL/On-Rev Database Tables

[Pierre Sahores]

Hi Rick,

I got exactly the same problems when i tried to setup my on-rev  
postgresql db (loki.on-rev.com) :


OK to create the db in using the PostgreSQL Database Wizard

No luck in trying to setup its contents in using the phpPgAdmin lib.

To avoid to have to setup the table in using the shell under SSH  
(because my standard DSL web acces use dynamic IPs), i switched to  
MySQL instead. It must not be so difficult (some files rights and  
users access to correct or so)


It would be great to have some one at Edimburg to reconfigure the  
phpPgAdmin config to let us use it as we can use the phpMyAdmin one.


Best Regards,

Pierre

Simple Arrays

[Bob Sneidar]

Hi all. 

Apparently I am not getting arrays AT ALL. I would think that given:

put "1" & comma & "A" & comma & "Green" & return into theData
put "2" & comma & "B" & comma & "Blue" & return after theData
put "3" & comma & "C" & comma & "Orange" & return after theData
put "4" & comma & "D" & comma & "White" & return after theData

which would get me:
1,A,Green
2,B,Blue
3,C,Orange
4,D,White

I could then split by column (or by row I get confused) and get a simple array 
where:
theData[1,1] = "1"
theData[1,2] = "A"
theData[2,1] = "2"
theData[4,3] = "White" 

And so forth. However, this is NOT the case! If it were, I could issue a 
command:

put transpose(theData) into myArray

and:
myArray[1,2] = 2
myArray[1,3] = 3

and so on. If I got the entire row (I think there's a function for that) then I 
would have effectively gotten the column of the original data. Seems reasonable 
eh?

So can someone please explain to me why I cannot get a simple x,y row,column 
grid-like array using these simple commands? Revolution seems to think that the 
first column MUST be the key! I would LIKE for revolution to simply create it's 
OWN numerical keys and let my data be my data. Maybe in the future add an 
argument to the split and combine commands to tell it whether or not I WANT 
Revolution to treat my first column as the key?

If arrays worked like I described above, it would be a simple matter to get a 
single column of an array, just by transposing it and getting an entire row, 
instead of writing complex repeat loops to get a column of data. Am I missing 
something here? 

Thanks for any wisdom you can give. I can save some helpful souls the trouble 
of responding by saying I am capable of making repeat loops to accomplish this. 
I was just hoping that maybe I was missing something and I can in fact do what 
I thought I could.

Bob, Maybe we can learn something about arrays together.

First, the format for a multi-dimensional array is

theData[1][1] = "1"   NOT  theData[1,1] = "1"

---
-- as an example, put your 4 lines into fld 1
---
1,A,Green
2,B,Blue
3,C,Orange
4,D,White
---
-- to get those 4 lines into a multi-dimensional
-- array called myArray I think you need code
-- like below (which you already know)
-- There might be an easier way.
---
on mouseUp
put fld 1 into v
set itemDelimiter to comma
put zero into countLine
repeat for each line curLine in v
add 1 to countLine
put zero into countItem
repeat for each item curItem in curLine
add 1 to countItem
put curItem into myArray[countLine][countItem]
  end repeat
end repeat
put myArray[1][2] into fld 2
end mouseUp
---
-- will end up with "A" in fld 2

Now for the transpose function.

>From the dictionary:

-- The array is a two-dimensional array variable whose elements are numbers, 
and whose keys are sequential numbers. --

So it looks like transpose will only work for two-dimensional arrays. It won't 
work for your example.

Actually either of these:

split theData with cr
split theData by row -- where the rowDelimiter is CR

would get you this:

theData[1] = "1,A,Green"
theData[2] = "2,B,Blue"
theData[3] = "3,C,Orange"
theData[4] = "4,D,White"


I could then split by column (or by row I get confused) and get a simple array

theData[1,2] = "A"
theData[2,1] = "2"
theData[4,3] = "White"

And so forth. However, this is NOT the case!


Right. Technically speaking, comma is not an array index separator. 
Commas in our array keys help us conceptually represent multiple array 
dimensions in our own minds, but Rev sees an array with such keys as a 
simple one-dimensional array with alphabetic keys (since commas are not 
numerals).


Until version 3.0, Rev couldn't handle true multi-dimensional arrays. 
Since then, the thing that tells Rev "this is a multi-dimensional array" 
is multiple keys per element, with each key in its own bracket. Like this:


theData[1][1] = "1"
theData[1][2] = "A"
theData[1][3] = "Green"


Now do you see why 'transpose()' wouldn't work with your array? In part 
it's because your keys aren't numeric - they contain commas. (Also they 
have to be sequential numbers.)


Welcome to array re-education camp!  ;-)

  If it were, I could issue a command:

put transpose(theData) into myArray

and:
myArray[1,2] = 2
myArray[1,3] = 3
