UnitTest-Bar never get green
by leeb＠anecon.com 31 Jan '02

31 Jan '02

It is very good to have tests for our UnitTests framework but I expect a green bar if I press RUN ALL unless a failure or an error appears someplace. The 2 tests (testFailureDebugUI and testDebugUI) which let the bar never get green, however, are there. Could we deactivate those two tests in the main distribution (Makes more fun to write UnitTests for Squeak)? keep squeaking Gerald.

(no subject)

I thought I would just ask this smalltalk list a couple of questions - I am new to smalltalk and this list has been highly recommended in solving most smalltalk problems - guess its because all of you are smalltalk gods or something... anyways... here it goes. I have a record subclass declared as follows: Object subclass: #RECORD - I have various methods for this. I want to make an array of records - so its one array that stores of type records - which I have defined I have tried the following: OrderedCollection subclass: #People - dont know what methods I need - do I have to have an initial 'instance creation'! This does compile but it complains at the following: Smalltalk at: #arecord put: (People new) ! Just complains about Object People - hangs. All I need is a way of storing these records in an array. I could use ARRAY instead of OrderedCollection but I want a dynamic array. If anyone knows how to do this - please can you get back in contact with me, I will add in all my own methods for my People subclass after I have the basic one working - so I can add records to it. Thanks ever so much - and keep up the good work - people look up to you guys ya all know :-) J _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp

I think it sounds great, and far preferable to >MP3 technically for several reasons (space, quality, scaling). Software >for it abounds. I second the motion. As soon as I understood all the legal issues surrounding MP3, I wanted to do an open alternative (hey, can't be *that* hard, right? ;-). Ogg Vorbis (see, eg, http://www.vorbislinks.com/) seems to be exactly this kind of movement and I am strongly in support of it. Squeak could be a neat synergy for them, and it would be a valueable tool for Squeak. - Dan [I apologize for the possibly redundant distribution to squeak-dev, but I think several people who aren't on SqueakAudio might want to know/think about this].

[M206] how to do M206 diagrams in Squeak
by John Hinsley 11 Jan '02

11 Jan '02

Just posted for fellow M206 sufferers a short HOWTO do M206 diagrams in Squeak. "It's CRC, Jim, but not as we know it". It's at http://www.penguin-home.telinco.co.uk/M206_diagrams Does anyone happen to have the URL for Mark and Lex's CRCCardMorph to hand?

[Linux][Newbie] Trouble installing Squeak
by Brent Vukmer 10 Jan '02

10 Jan '02

Hello Squeak folks. I am trying to install Squeak to my user space in a box running Red Hat 7.2, that I'm connecting to via VNC. I downloaded the Squeak 3.0 source, image, changes and image file from the links found at http://www-sor.inria.fr/~piumarta/squeak . I followed Ian's instructions -- except that I don't have root privileges, so I copied the executables to ~/bin. When I change to the working directory that contains the image, source, changes files, and run "squeak Squeak3.0.image", I get the message "Visual class TrueColor is not supported at depth 8." at the command-line. No Squeak :(.

Re: Losing my latin

> Context: > I cannot find where a comment is stored in a returnNode or its child like > the comment at the end of this method. Stephen, I've pretty much decided that Squeak's parse nodes are best left for *compiling*, not for analysis. I had a rough time just decoding what variable a variable referred to, for example. This would appear to be another example of the problem. I'd recommend my "Lucid" parser, but actually, I think it completely discards comments, so no luck. :| There are other Smalltalk parsers floating around, however. It would be nice if Squeak had an analysis-friendly parser in it. But Smalltalk is such a simple language, everyone seems to just cobble together a parser for their own needs. -Lex

SUnit for XML?
by Michael Rueger 08 Jan '02

08 Jan '02

Hi all, are there any (SUnit) test cases for XML out there? I used to test Yax with a bunch of test files from James Clark's test suite (http://www.squeaklet.com/Yax/xmltest.zip), but never got around to create a real test suite out of it. As far as I can tell Yax handles a lot of the semi-validating stuff (extending entities, namespaces, system and public ids and such) but this impression is more based on "anecdotal" testing ;-) A test suite would give as an objective measure of what works with which parser and would provide a list of points to work on. Oh, and benchmarks would be great, although Shakespeare (http://www.ibiblio.org/xml/examples/shakespeare/) provides nice lengthy files :-) Michael

Hi Karl, I made a mistake. The Smalltalk code needed to run the latest version of the plugin is at: http://groups.yahoo.com/group/squeak/message/37086 In my previous message I directed you to an older version. Please file in that thange set, and the plugin should work OK. This cs will get in the update stream real soon anyway. I'm sorry for making you loose your time.

Update on the Squeak-material on my site
by Maarten Maartensz 02 Jan '02

02 Jan '02

L.S. It may interest some to know that I have given Squeak its own directory on my site and have extended the html- versions of my user manual (in progress). The relevant direct link is: http://www.xs4all.nl/~maartens/squeak/squeak_index.htm It contains almost 700 Kb of Squeak-related files on the moment, nearly all of which is in a transitional stage (and so is expected to be extended or rewritten in the none too far future, to end up in a Squeak Project). Having seen my own site recently on a local internet-cafe, that did not display part of my site as it should (probably due to a combination of factors including MS buggery): - my site should display in Arial 12 point bold - and is best read in 1024*768 resolution The letter I prefer is fairly large because of my none too good eyes and health (and the 1500 files I maintain on my site), and you can easily get rid of it by means of your browser if it displeases you. (Also, for some learned academics of acute logical awareness: If I talk about Squeak on my website the text really IS in html and - alas! - not in Squeak. It is true this is a logically subtle point, for some.) Finally, I am on the digest-form of the developers-list only, since I have no really useful code to contribute, and since I find it none too constructive to discuss philosophy etc. (including my own) on this developers list. I wish everyone on the list a happy, healthy and peaceful 2002! Regards, Maarten. -------------------------------------------------------- Maarten Maartensz.
