How to intercept every instance variable write on all objects

by Petr Fischer

Hello, is possible to intercept (before writeÃº all instance variable writes on every existing objects? I found a discussion here: http://forum.world.st/Is-it-possible-to-follow-an-object-through-a-computat… Known solutions: 1) jugglery with object read only state + ModificationForbidden - not ideal, it's probably slow via exceptions and every nested on:do: stop change detection 2) it's possible to do it via slots - but it does not work on any existing object (only on my specially prepared objects with slots) 3) Metalinks - it's based on intercepting method calls, right? But I need to intercept direct instance variable write, so probably not possible Is there any way? Thanks! pf

Re: [Pharo-users] Corrupted fonts in P7 after loading Glamorous Toolkit

by Tim Mackinnon

As an observation that might help with this - Iâve not been able to recreate the corruption after I had re-saved the image and cured the original corruption. I will go back to my original starting image and see if I can corrupt it from there (previously I had been able to). So Iâm not sure why that save and subsequent font cache reset would hold when it didnât seem to before.

Thanks HernÃ¡n and Cyril. Although I've been a programmer since 1977, with professional experience in functional and object-oriented development, I'm a total newcomer to the Pharo/ST ecosystem. Your replies are much appreciated.

Even simpler: Just inspect: Integer>>#factorial. and one of the tabs is the source code. You can also do: (Integer>>#factorial) browse. > On 31 Jan 2019, at 17:38, Cyril Ferlicot <cyril.ferlicot(a)gmail.com> wrote: > > > > On Thu, Jan 31, 2019 at 5:23 PM David Richards <david.i.richards.iii(a)gmail.com> wrote: > Thanks HernÃ¡n. > > Smalltalk tools browser open. > > This code expression is helpful to see and understand. > > My question goes further however -- to how we can open the browser to display a specified method of a specified class (e.g. the 'factorial' method of class 'Integer'). > > > Hi, > > Smalltalk tools browser openOnMethod: Integer>>#factorial > > David > > > > -- > Cyril Ferlicot > https://ferlicot.fr

Hi David, You can open the browser on a method using #openOnMethod: Smalltalk tools browser openOnMethod: (Integer>>#factorial) Cheers, HernÃ¡n El jue., 31 ene. 2019 a las 13:23, David Richards (< david.i.richards.iii(a)gmail.com>) escribiÃ³: > Thanks HernÃ¡n. > > Smalltalk tools browser open. > > This code expression is helpful to see and understand. > > My question goes further however -- to how we can open the browser to > display a specified method of a specified class (e.g. the 'factorial' > method of class 'Integer'). > > David > > On Thu, 31 Jan 2019 at 07:10, HernÃ¡n Morales Durand < > hernan.morales(a)gmail.com> wrote: > >> Hi David, >> >> This is the way: >> >> Smalltalk tools browser open. >> >> Cheers, >> >> HernÃ¡n >> >> El jue., 31 ene. 2019 a las 8:57, David Richards (< >> david.i.richards.iii(a)gmail.com>) escribiÃ³: >> >>> From 2018-09-29-UpdatedPharoByExample.pdf page 20: >>> >>> [image: image.png] >>> >>> How to do this with Calypso? >>> >>> Smalltalk tools openClassBrowser ...?... >>> >>> Thanks. >>> >>

Thanks HernÃ¡n. Smalltalk tools browser open. This code expression is helpful to see and understand. My question goes further however -- to how we can open the browser to display a specified method of a specified class (e.g. the 'factorial' method of class 'Integer').
