A CompiledMethod is immutable, so every time you change a method, a new CompiledMethod object gets created. So, if the browser shows CompiledMethods, you will always see the old version. This would have been the same without Glamour as well. That is why you need to show a RingMethodDefinition which only holds a reference made by the name of the method that is resolved dynamically. > To make it perfect, there is still a fix needed for the DrGeo script browser: > > The class method 'scriptName' of each Dr. Geo script class returns a string, it used in the browser (and other place) to list meaningfully the script (and not use the generic class name). > > Therefore, when the user edit this method, the script name listed in the left panel should be updated accordingly.

Is it the right way to do it? constructor fastList creates a CompositePresentation that holds a ListPresentation. Think of a CompositePresentation as a morphic pane: it is a holder without much logic. The data you want to update is dealt with by ListPresentation. Thus, what you want to update is the list, not the whole composite. scriptsIn: constructor constructor fastList title: 'Scripts' translated; display: [ :organiser | organiser ]; format: #scriptName; updateOn: MethodModified from: [ SystemAnnouncer uniqueInstance ].

Re: [Pharo-users] Creating the smallest server runtime footprint

by Tim Mackinnon

Related to this question - in the Linux vm there are several .so files that have numerical extensions as well as the same named .so file. Are these merge conflicts or platform variations of the same files? E.g. libSDL2-2.0.so.0.4.1 & libSDL2-2.0.so & libSDL2.so Are all in there?

Creating the smallest server runtime footprint

by Tim Mackinnon

Hi - buoyed by the success of a minimal image (thanks Pavel), I'm wondering if I can get even smaller. There are lots of .so's in the vm which wouldn't make sense on a server once deployed - sound, maybe libgit ... Is there a list of the essential ones, or tips on what I can strip out of the Linux deployment? I also recall that i can leave out .sources and .changes as well right? Tim Sent from my iPhone

Re: [Pharo-users] Glamour: update presenter with new text

by Hilaire

Thanks Doru, it works as a charm! I don't think I could find it by myself, or I will have to become a Glamour expert. To make it perfect, there is still a fix needed for the DrGeo script browser: The class method 'scriptName' of each Dr. Geo script class returns a string, it used in the browser (and other place) to list meaningfully the script (and not use the generic class name). Therefore, when the user edit this method, the script name listed in the left panel should be updated accordingly. I edit the code as bellow: scriptsIn: constructor constructor fastList title: 'Scripts' translated; display: [ :organiser | organiser ]; format: #scriptName. * constructor updateOn: MethodModified from: [ SystemAnnouncer uniqueInstance ].* It gives the expected behaviour. Is it the right way to do it? Thanks Hilaire Le 13/07/2017 Ã 11:50, Tudor Girba a Ã©crit : > > I took a quick look.

Peristence with SandStone or Voyage -> Bypassing the saving of a variable.

by sergio ruiz

So, I tried using mongo voyage for persistence of my Models, and when trying to the SsStateMachine, Mongo Voyager had problems figuring out what to do with my state machine..Â So, it occurred to me.. the state machine really does nothing but guide the order through its journey. By the time the order is complete, the state machine is irrelevant.. and there is no chance that the state machine will ever be relevant..Â So, my question is..Â Is there any way to mark a variable (like statemachine) as âdo not persistâ?Â This would solve all my problems..

Re: [Pharo-users] Using SandstoneDB for persistance. Getting error.

What is happening is that when the StateMachine gets set up in order initialization, the guarded condition is set.. when you pass a MessageSend to it, it just evaluates to the value of that message send on initialization.. When you pass a block to it, the block is evaluated every time the call is made..

Re: [Pharo-users] Is there a 64bit minimal image for either 6.0 or 7.0?

I think there is something wrong with the minimal image - but it looks like the following has nudged me a bit closer (rather inelegantly but I think the minimal images may need checking for errors): MCFileTreeRepository methods do: [ :m | m recompile ].

Re: [Pharo-users] Is there a 64bit minimal image for either 6.0 or 7.0?

Thinking about this a bit more - if the minimal image is too minimal, and I load in some required classes - do I need to force methods to recompile to pick up the now loaded classes? Is there an easy way to do that?
