Could you use a metacello configuration named SciPharo composed of packaged that you would pick from a more neutral repository? 2016-03-04 8:28 GMT+01:00 Benoit St-Jean via Pharo-dev < pharo-dev(a)lists.pharo.org>: > > > ---------- Message transfÃ©rÃ© ---------- > From: Benoit St-Jean <bstjean(a)yahoo.com> > To: Pharo Development List <pharo-dev(a)lists.pharo.org> > Cc: > Date: Fri, 4 Mar 2016 07:27:45 +0000 (UTC) > Subject: Re: [Pharo-dev] Call about Numerical Methods in Pharo :) > Why just don't we honor Didier H.

Mocking networkâ¦
by Yuriy Tymchuk March 3, 2016

March 3, 2016

HI, there is one thing in Ruby (on Rails) that I really like and it is a option to mock network. This means that when you run a test your network requests are handled by a mock object and you can tell it that for this URI it should give you this response. This is helpful if you donât want to rely on a network availability or test certain corner cases. Is there anything like this in Pharo? Uko

[FFI] DNU ByteArray>>#rollAsDoubleToArity: arity
by Aliaksei Syrel March 3, 2016

March 3, 2016

(In the latest FFI) Assume we have a native call declaration (we want to *get* values from x and y later): primGetCurrentPointX: x Y: y > <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: > errorCode> > > ^self nbCall: #( void cairo_get_current_point (self, *double * x, > double * y*)) Trying to use it as: | x y | > x := (ByteArray new: 8). > y := (ByteArray new: 8). > self primGetCurrentPointX: x Y: y. > ^ (x doubleAt: 1)@ (y doubleAt: 1) Throws DNU ByteArray>>#rollAsDoubleToArity: arity . However if primitive would be modified to: ^self nbCall: #( void cairo_get_current_point (self, *void** * x, void * y* > )) Exception goes away. I'm just curios how it is supposed to be :) Cheers, Alex

issue 15733 - OK to change the test?

See http://forum.world.st/The-Inbox-System-mt-697-mcz-td4802003.html for the orginial discussion that this fix is attempting to fix.

But that means I'll have to update the MessageTallyTest>>#testTallySends to reflect the new report. Does that sound OK?

A question about the Dark Theme main background color
by Sven Van Caekenberghe March 3, 2016

March 3, 2016

I know that colours are a matter of taste, but I have a question about the Dark Theme main background color. Here is a screenshot of my 4.0 image: Versus the same in 5.0 Note how the background of the contents of windows is much darker, the contrast being very hard. Was this an intentional change ? Does the majority prefer that colour ? How can I change it back to the softer one ? Thx, Sven BTW: Also note how much less space there is for the real code (yes I use pretty large fonts, but they are the same in both), how much space is lost in decoration around code in Nautilus, how busy it looks ... just my opinion.

Can't enter Square Brackets in new images
by Udo Schneider March 3, 2016

March 3, 2016

All, I'm currently chasing a strange problem with new 5.0 based Images. In the regular Pharo 5.0 Beta Image and current Moose (5.1) Image you can't enter square brackets anymore. It seems to change the class/category/method selection in Nautilus and causes a non-breakable loop of discarding/ignoring/saving the changes dialog for changed methods... Checking the same VM with older 5.0 images works w/o any problem. So I assume an image problem - not a VM problem. Has anyone seen this? I'm currently testing on Mac OS X with a german keyboard and US-English locale. Will test on Windows tomorrow. CU, Udo Pharo 5.0 Details: Smalltalk image version.
