sound and squeak / siren
by jacob remin 27 Dec '06

27 Dec '06

hello (and merry xmas!), i am interested in building a simple experimental musical instrument. i am wondering where to look for nice packages of functionality. i am interested in some quite basic functions: - sampling/recording sound - sample playback - filtering (VST plugin support?) - MIDI support - audio visualization can you point me in the right direction? so far, i have stumbled upon siren and um0, but are having some troubles installing them: it seems siren is only for visual works? i have downloaded the smalltalk package from the siren homepage http://www.create.ucsb.edu/Siren/ , but is this importable to/compatible with squeak (and how?) um0 downloads nicely with the squeakmap package loader, but gives me an error during install: can't find EOCD position. what to do? thanks! sincerely, jacob remin

I have to check this up. currently you should go to this page: http://www.zogotounga.net/comp/squeak/sqgeo.htm and follow point (2) so you will have the packages already cached in a local /sm folder. then the installation should proceed smoothly. please let me know of any trouble. > I don't know what um0 is and I don't see it in squeakmap. What is it? muO (or µO) is an environment for experimental musical composition. still in developement but already fun enough I believe. Stef

3.9 issues...
by Blake 23 Dec '06

23 Dec '06

I've finally had a chance to play with the Squeak 3.9 release under Windows. I like the main toolbar, the look and functionality. It causes an error if I click on the view-world-hierarchy icon, a particularlly frustrating one since it doesn't actually appear and the screen seems to lock up unless you tab to Squeak. This doesn't seem like it's fully done, so I'm not sweating it. What really is troubling me is that I can't seem to make the Workspace work. I'm not sure if the key-bindings have been changed to Ctrl from Alt, but neither Ctrl nor Alt + D/I don't seem to work, i.e, there's no indication that they're doing anything, they don't seem to produce any results (although the D seems to occasionally erase everything selected). Anyone else experiencing anything like this? ===Blake===

Win32 OS functions

Hi I want to play around with some cross-thread and cross-process stuff in Windows XP. E.g. memory mapped files, windows message sends, named pipes and so on and was wondering how to access these methods in Squeak. Any pointers would be welcome.

Re: Block evaluation
by Jerome Peace 19 Dec '06

Block evaluation Hi Ulli, I tried your code out in a workspace. Here is what I discovered. The original: | x y z | x:= [ y:=1. z:=2. x+y. ] . x value. {[y := 1. x := 2] } . Ah this is a cool bug. As you probably know, "[ anything ]" is an object called a block context x:= [ anything ] . x value . will print the value of "anything" in this case "nil" since we have not defined it. There is a typo (I believe) in your second line. I am guessing you wanted to write. x:= [ y:=1. z:=2. z+y. ] . x value. which gives the result 3. as it stands you are trying to add a number to a block context which gives a DNU. The last line is also interesting Try { y:= 1 . z := 2 } ans: " #(1 2)" or {[y := 1. x := 2] value }" ans: #(2)" or {[y := 1. x := 2] } first value " 2" The square brackets are causing the evaluation of "y := 1. x := 2" to be delayed until later. The thing that prints out what is going on it being more cryptic than it needs to be by not printing the contents of the block context which you would have more immediately recognized. hth.

Stop a script for a second
by Martin Bleichner 19 Dec '06

19 Dec '06

Hi together, I am new to this list. So perhaps I should introduce myself. I am 25 year old german student studying congitive neuroscience in Utrecht/Netherlands. I want to use squeak /etoys mainly for exploring and visualizing some ideas in a quick way. Right now I want to build a prototype for an experiment and think that this is a good project to learn a bit more about squeak. I want to program a sequence of objects appearing on different positions on the screen one after the other and later in a random order. A very dirty way to do so is just script doing something like. object1 show. script wait for 1000ms. object1 hide object2 show script wait for 1000ms. I know that this is a very basic question but couldn't find the answer, as I don't know what it is I am looking for. thanks a lot martin

indenting code
by Norbert Hartl 13 Dec '06

13 Dec '06

Hi, I'm asking myself if there is any common sense about how to indent the code in smalltalk/squeak. Most of the time I see something like statement do: [ :parameter | otherStatement selector: [ mostinnerstatement ] ]. or statement do: [ :parameter | otherStatement ]. Is this indenting common? Is the difference between those two above depending on the length of the line? If it is, how long are lines supposed to be? etc. Any hints or links are appreciated. thanks, Norbert
