Categorise method defaults?
by Tim Mackinnon Aug. 10, 2014

Aug. 10, 2014

When using Pharo 4.0 - if I create a new class (subclass of Object) and then create a new class method for constructing that instance - when I try to classify the method why is the list of possibilities empty? In old versions of squeak I recall there was a list of possibilities already in the image to choose from? I was expecting âinstance creationâ to be there already for me? Am i missing something? Tim

The tedious split between class and instance?
by Tim Mackinnon Aug. 10, 2014

Aug. 10, 2014

The more I use Pharo again - the more it strikes me how tedious it is to have to flip between instance and class side definitions. For example - if I create a new class with an instance variable, and then in my class constructor method decide that it would be handy to do: ^self new children: items; yourself But I donât yet have the #children: method - if I select the create accessors refactoring (while still looking at my class method) - it does nothing because I have an instance variable not a class variable. So I have to switch to the instance side, to use this refactoring and then flip back to writing my class method. This is really tedious - we really should find a better way to do this, as it eats away at your programming flow. Itâs not the language - its the toolsâ¦ Tim

Website redirects?
by Tim Mackinnon Aug. 10, 2014

Aug. 10, 2014

Guys - some of the URLâs on the pharo website have changed - I think it would make sense to have redirects instead of a Not Found error? e.g. http://www.pharo.org/get-help Just saying? Should I raise a ticket for this? Tim

Any thoughts on improving MC browser?
by Tim Mackinnon Aug. 9, 2014

Aug. 9, 2014

I was just about to ask how do I compare two arbitrary versions in Monticello - as I canât multiselect - until I realised that the Diff button prompts you for a version against what you have currently selected. This is a very weird UI experience. Now that we seem to have multi-select widgets - are there any proposals to improve MC? Tim

PharoLauncher can only run 1 instance on OSX?
by Tim Mackinnon Aug. 9, 2014

Aug. 9, 2014

I really like the PharoLauncher project - itâs very handy. However Iâve noticed that on OSX when I launch an image and then try and run PhaorLauncher (e.g. pharo.app) again, it just switches me to my already running image? Anyone know why it does that - or if there is some way to avoid it? iâm wondering it its the way that the launcher, launches the images (is it an os sub-process or something - and so this is why it just switches back to that process if you try and run it again?).

Accessing DLLs in Smalltalk/V
by Bob Williams Aug. 9, 2014

Aug. 9, 2014

I found an old Smalltalk/V imagine from 2000 and tracked down how I was able add calls to Windows DLLs and to add my own. It was in the class DynamicLinkLibrary and its subclasses, e. g., a call to the GDIDLL to draw a Bezier spline (which I believe I added) was: bezierTo: hDC lpPoints: anLPPOINT count: anInt <api: PolyBezierTo ulong struct ulong boolean> ^self invalidArgument I added by own DLL to do matrix transformations that was written in ASSEMBLER to optimized the floating point processor pipelining (a start operation every cycle while it took 3 cycles to complete) and it performed about 15% better. I have not found anything similar in Pharo, but it must if external libraries are used. NativeBoost seems to come close, but I cannot find any documentation. Can someone point me to some documentation, code, anything? It is greatly appreciated. bw

Always asking for developer initials in 4,0?
by Tim Mackinnon Aug. 8, 2014

Aug. 8, 2014

Iâve noticed quite a few times now in the Pharo 4.0 images - that I keep getting multiple prompts to enter my developer initials. I canât put my finger on it - I think its when I open a SystemBrowser in a new image - and just edit a class comment (it then prompts me for initials which is correct). However, if I then open the World Help - and then go back to my class comment and enter some new text - it often prompts me again? After doing this a few times - it then seemed to stick - so Iâm not exactly sure what causes it (this was in build 40123 - so reasonably recent). I mention it in case someone else has noticed this as well. Tim

by Torsten Bergmann Aug. 8, 2014

Aug. 8, 2014

Hi, the Bootstrap project (http://smalltalkhub.com/#!/~TorstenBergmann/Bootstrap) was updated to include the latest Twitter Bootstrap library v.3.2.0 from http://getbootstrap.com Also you can now use: - an RTL/LTR version included for BIDI language applications (see #bootstraprtlminCss and #bootstraprtlCss - #tbsContainerFluid beside #tbsContainer. How to try out: =============== 1. load "Bootstrap" from Configuration browser in Pharo 3.0 2. evaluate ZnZincServerAdaptor startOn: 8080 3. point browser to http://localhost:8080/bootstrap Side note: As the config also loads newer seaside you may also notice the return of the "Seaside Control Panel" in the Tools menu aftwards where you can also control the server as described in the regular Seaside docu. Enjoy! Bye T.

Managing updates/patches in Pharo with Metacello
by Esteban A. Maringolo Aug. 8, 2014

Aug. 8, 2014

Hi, How do you manage released versions updates in Metacello? E.g. I have a version 2.1, with its spec with a dependency to 'PackageA.11.mcz'. Later I find a bug which requires a new version of PackageA.11.mcz, everything goes ok as in the development/bleedingEdge version, which doesn't specify the file name, but how should I "backport" the change? What I am doing now is changing the version spec for '2.1' and updating the reference to 'PackageA.11.mcz' to 'PackageA.12.mcz', but I'm afraid this isn't the proper way of doing this. How do you manage this? In git I'd merge the commit in the 2.1 version branch, and then the CI that depends on such branch would incorporate the change. Regards! Esteban A. Maringolo
