[Pharo-project] OT: windows explorer weirdness workarounds?
by Schwab,Wilhelm K Jan. 16, 2010

Jan. 16, 2010

Hello all, No good deed goes unpunished. This time, I'm having win 2008 thrown at me. The deal is not all bad, but I see that the Windows explorer is just as whacked up as on Vista (which you might recall I gleefully replaced with Ubuntu and have not looked back). The changes to the folder list and complete absense of a horizontal scrollbar (and associated jumping in place of same) are really driving me nuts. Have any of you found ways around these changes? So far, I have found plenty of posts complaining of the GUI changes, but none explaining how to fix it. Any pointers would be greatly appreciated. Bill

[Pharo-project] Smalltalk interactive tutorial in good English
by laurent laffont Jan. 15, 2010

Jan. 15, 2010

Hi I've written a sort of interactive tutorial based on (old) Stephane's screencasts about Smalltalk syntax. It's called PrStef ;). To load it: Gofer new squeaksource: 'PrStef'; package: 'PrStef'; load. and to run it: PrStef go. I'm looking for English-speaking people to check that the texts are written in a correct English before I make a screencast on it. Thank you ! Cheers, Laurent

[Pharo-project] mac vm version number on pharo-project.org/pharo-download page
by John M McIntosh Jan. 15, 2010

Jan. 15, 2010

I noticed the mac vm version number on pharo-project.org/pharo-download page is wrong, it says 4.2.2b2 but actually it's 4.2.2b1 If someone can correct it, that would be great and it will keep me from thinking I've managed to misplace a VM somewhere... -- =========================================================================== John M.

[Pharo-project] VB-Regex News
by Lukas Renggli Jan. 15, 2010

Jan. 15, 2010

Gofer new renggli: 'unsorted'; package: 'VB-Regex'; load - The VB-Regex engine has 160 new SUnit tests that cover 88% of the code-base. A few tests I wrote myself, but most of it comes from the class-side of RxParser that had an ad-hock test suite that painfully logged its results to the transcript. - I fixed the issue with the duplicated matches that was reported here <http://code.google.com/p/pharo/issues/detail?id=1747>. Unfortunately Vassili Bykov did not answer my questions. The fix is quite ugly and I had to rewrite most of the logic in RxMatcher. The test pass, but there might be new bugs. - The bad news is that matching is roughly 7% slower. I guess that's the price to pay for correct results.

[Pharo-project] MC case sensitity and sub-packages
by Schwab,Wilhelm K Jan. 15, 2010

Jan. 15, 2010

Brian and others have told me that I could expect to define packages such as DolphinCompatibility-ODBC DolphinCompatibility-Streams and save them all using DolphinCompatibility, or save just one specific part by giving the full name, such as DolphinCompatibility-ODBC. I was unable to make it work reliably, and I think I might have just figured out why. Assertion: package names and class names must agree up to case; method categories (*packageName-etc) appear to be more forgiving. It further appears that once one messes up by naming a category and package Dolphincompatibility instead of DolphinCompatibility, the only way to fix it is to delete the working copy of the package and re-create it with the correct case after renaming the category, or something like that. Does that sound right? Am I missing something that might cost me later? Bill

[Pharo-project] Regex regression?
by Schwab,Wilhelm K Jan. 15, 2010

Jan. 15, 2010

A lot is happening, so I could be off here. In the 10496 web image, I noted that there might be problems with the regex package. Now trying to build a new image I hit a walkback over '*username*' asRegex Any other takers? I am seeing this problem in both 10496 and the new RC1 on the download page. Bill
