Broke nastily on windows with confusing exceptions and leaking file handles iirc. BTW, opening an image twice at the same time on windows give the "changes file not accessible" popup at startup of the second image.

[Pharo-project] Recent MC doesn't support loading classes with nil superclass?

by Igor Stasenko

Tested both in Pharo-Core & Squeak trunk image. The class i defined is: ProtoObject subclass: #BBBNameOfSubclass instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'NILSuperClass'. BBBNameOfSubclass superclass: nil In attachment you can fin the fileout of it. And MC package, saved with it. If you try load the package, MC will display warning that you should resolve dependencies 'nil' before loading the class ;) Background: I wanted to migrate to newer image and saved my package, im working on, which i didn't touched for 3-4 months, and found that it can't be loaded :( -- Best regards, Igor Stasenko AKA sig.

Re: [Pharo-project] Opening image multiple times - bug or feature?

by John M McIntosh

Actually the WIndows VM use to lie, might still, if you opened a file READ/WRITE but it was read only, like on a CD, then the windows VM would say SURE no problem. This caused grief for macintosh users using one- click apps on a CD because we would cause a walkback saying we couldn't open the file READ/WRITE. The *fix* in etoys was to alter the file open (read/write) and silently fall back to saying oops try again (read-only) if it fails. Versus fixing all the places where you opened a file for reading, but as read/write (by default).

This also applies to in-image code which can make for interesting platform dependant bugs when running on platforms that don't allow this, like windows.

Well you can try it by going to the http://www.wolframalpha.com typing in a formula and see what the URL turns into. There might be a guide somewhere, I didn't look. 1+(3/4)-2.5e2+2^3 http://www.wolframalpha.com/input/?i=1%2B%283%2F4%29-2.5e2%2B2%5E3 -961/4 On 2009-09-24, at 3:06 PM, Michael Roberts wrote: > Hi John, slightly OT but do you know if you can give arbitrary > mathematica syntax to wolfram Alpha? i was trying to use its > functional programming model but it tends to ignore my syntax and get > confused.

Hi John, slightly OT but do you know if you can give arbitrary mathematica syntax to wolfram Alpha? i was trying to use its functional programming model but it tends to ignore my syntax and get confused.

Re: [Pharo-project] closure fixes nearly released

by Michael Roberts

looks good to me... but then i would say that! The method properties tests are now wrong, because they perform their assertions on the AdditionalMethodState without knowing it. We could either look to rewrite the tests to provide some test coverage for the new class, or just delete them. I haven't looked at the highlighting tests in depth but i know there is more work required there. it's quite tricky, not for 1.0. I think the ability to recompile the system and run the 7000 odd tests should give us some confidence. Obviously some wider review would be good. cheers, Mike
