Re: [Pharo-project] Where should debug file name be?

by StÃ©phane Ducasse

There is no fight.. - first we would like to see if class can be lookup dynamically (and cached) - second Smalltalk tools log does not hard code yet another global. We got problem when we want to change code in the compiler that relied on transcript when we changed transcript. At the end we removed the message because it was useless but this illustrates the point.

To my pleasant surprise/amazement, a walkback appeared and the debugger was functional; I was able to evaluate the accessors and get numbers. Is this dangerous in some way, or does it "just work?"

Re: [Pharo-project] About NonInteractiveUIManager>>#onSnapshot: and related

the logic there was to set a non-interactive ui manager for headless sessions only , and then restore back a previous one (whatever it is), once session is changed back to headfull. if its uiManager is nil, it should reset the default manager, if i remember correctly, then UImanager itself will take care instantiating default one.

[Pharo-project] About NonInteractiveUIManager>>#onSnapshot: and related

by Guillermo Polito

Hi, I was doing some hacking, and playing with NonInteractiveUIManager. And it puzzled me that I realized that it has an inst var *uiManager* that seems to refer to an uiManager it's replacing. But my UIManager is not replacing anyone, it's my default and unique UIManager and this var points to nil :S! So the code below does not work... onSnapshot: resuming "The resuming argument is true when image boots from disk, and false, if user just did an image snapshot." resuming ifTrue: [ Smalltalk isHeadless ifFalse: [ "restore old, or nil, so it will be set in #default " *uiManager beDefault. UIManager default onSnapshot: resuming.* ^ self ]. Smalltalk isInteractive ifTrue: [ "use a headless but interactive manager" ^ self headlessManager onSnapshot: resuming ]]. " this flag set to true only if we are saving a snapshot before quitting " doNotQuitOnRestart ifTrue: [ Smalltalk snapshot: false andQuit: true]. I made it work in my image adding within the controversial lines: uiManager ifNotNil: [ * uiManager beDefault. UIManager default onSnapshot: resuming.* ] But it really looks like a hack because that inst var is ment to do something else... Is it asking me for a refactor? Or am I using this stuff in the wrong way? Camillo, Igor? :P Guille
