Re: Unix sound bug not fixed in 2.3 beta.
by Lex Spoon 02 Dec '98

02 Dec '98

I'm not sure why, but synchronous support hasn't worked for a few versions now, and I'm not planning to fix it. The page actually says this, but a lot of people don't notice. (I just fixed the page to be a little more explicit; the update will take effect at 6am tomorrow). Anyway, try it with asyncronous support and see if THAT works.... And be sure to turn UseReadySemaphore back to 'true'.

ANSI Exceptions Ready For Trial
by R. A. Harmon 02 Dec '98

02 Dec '98

I've finished sorting out the problems I had with my ANSI Exceptions implementation. It works as far as I can tell and runs my test code. I think it's a good bet that it's not entirely correct, so I'm asking if anyone would like to try it out. I'd like to see someone who has some knowledge or experience try it before I post it for general use. I'd like to know if it is a useful starting point for a reasonably conforming implementation of the ANSI proposed standard within the limits of the given compiler. It assumes an unaltered version Squeak2_0.zip (1998.07.16 10:01:02 3,227,382) on Windows 95. A couple of non-conforming areas are: ScaledDecimal behavior is not implemented. Squeak doesn't allow the literal #'string' to specify a symbol. Anyone one who would like to give it a test run, send me an email off the list and I'll send back the zipped file. It's 45K so let me know if this is a problem for your mail space. The code I'd send will include a SIF reader/writer, and the Fundamental, Valuable, and Exception protocols, and an installation script. It is minimally commented at this point, but does have at least one piece of test code for each ANSI message. Any help would be greatly appreciated. -- Richard A.

How To Open Transcript?
by R. A. Harmon 02 Dec '98

02 Dec '98

If an error occurs in reading a file, I want to open a Transcript window, when the first error is encountered and show that error message, then show any subsequent error messages. I have opened a Transcript window but control doesn't return (I think) to the point after the open stuff and continue executing. Any advice on how to do this would be appreciated. -- Richard A.

Comment ANSI Messages?
by R. A. Harmon 02 Dec '98

02 Dec '98

I've added facilities for globals, pools, pool variables classes and methods annotations such as comments, author, etc. I'd like to add comments for ANSI messages that in effect would be a link to a the description of that message in the proposed ANSI standard document in HTML format. I could then click on that link to bring up a browser on the ANSI standard document showing the message description. It doesn't necessarily have to bring up a browser, but this would then allow me to look at other areas of the document if needed. I'd appreciate any suggestions on how to do this. I originally thought of just including the message description text in the comment, but this would add a ton of stuff to the development environment and then I still have to deal with links for multiple methods that implement a protocol message. I also considered storing the position (RemoteString) of a message description in the standard document in text format. This starts to get complicated with establishing and maintaining the position of a message description. I would really like to find an effective mechanism that is also as simple as possible as I'd need to implement it in Smalltalk Express, Dolphin Smalltalk, and others which aren't as advanced as Squeak in some areas. -- Richard A.

The Univ of CO at Boulder probably has a nice book or two in their bookstore though I don't have any names. Try the upper level Astronomy or Physics courses. A seach on Amazon gives a number of choices, but, a lot of those seem to be related to astrology :-( If you want a program you can use xephem from http://iraf.noao.edu/~ecdowney/xephem.html, or, its older cousin ephem. If nothing else, xephem will give you loads of source :-) JPL seems to have a group interested in these sorts of things at http://ssd.jpl.nasa.gov/.
