O'Reilly Squeak book?
by cg＠cdegroot.com 28 Apr '02

28 Apr '02

Just on c.l.s., there's talk on why there's no O'Reilly book on Smalltalk and how that would help acceptance (anything that comes with an "animal book" is instantly taken serious). Although I responded that it would be hard (no single Smalltalk product is probably big enough to warrant a book, and a book that would talk about all implementations would be - by necessity - too vague for O'Reilly), it might be worth trying to draft up a proposal to O'Reilly for a Squeak book. They've published funkier stuff, and it might be a big boost... Would it be an idea to try to collect a small group of people to work on a proposal? -- Cees de Groot http://www.cdegroot.com <cg(a)cdegroot.com> GnuPG 1024D/E0989E8B 0016 F679 F38D 5946 4ECD 1986 F303 937F E098 9E8B

Q: How to detect shift down
by Ross Boylan 28 Apr '02

28 Apr '02

I am in a morphic project trying to detect if the shift key is pressed. I have tried a bunch of things like Sensor shiftPressed InputSensor default anyModifierKeyPressed (with ctl, since comment says it ignores shift) but it always returns false. What's the trick? By the way, I'm just doing this so I can say Sensor leftShiftDown ifTrue: [self halt] so that the halt doesn't stick me in a loop.

[Q] how to sleep(1)
by Martin Drautzburg 28 Apr '02

28 Apr '02

What is the easiest way to put off a certain action while still processing input events ? Something like (sleep 1; do_something)& in bash or an after 1000 in TCL.

Mailing list error messages
by Ken Causey 28 Apr '02

28 Apr '02

The mailing list software seems to be sending me error message for each of my posts that is not deliverable to someone subscribed to the list. I'm guessing this is the case because I receive a varying number of seemingly identical error messages each time I send a message to the list. I ignored this for a while, but it has been occurring now for several days. If someone would like a copy of one or more of said error messages, just let me know. Ken Causey

[FIX] sndPlugComments-ls
by Lex Spoon 28 Apr '02

28 Apr '02

I just spent another couple of hours decoding what the sound primitives are expecting. Perhaps these three comments will help the next poor sucker that messes with this stuff. I'm no expert here, so someone should definitely review them... -Lex from preamble: "Change Set: sndPlugComments-ls Date: 28 April 2002 Author: Lex Spoon Updates three sound-related comments regarding sound data formats" !
