Hello, In the meantime I found the password reset page: http://map.squeak.org/mailnewpassword But I always get a timeout error: > 504 Gateway Time-out > > ________________________________ > nginx/1.16.0 Is there something wrong on the server?

cannot read file format 6521
by stes 03 Apr '20

03 Apr '20

Hi, Is there an easy way to see in the squeak image file name what the "image format" number is ? I've built squeakvm from SVN (subversion) on Solaris. This compile went relatively well. I've used the SunPro C Studio "DeveloperWorks" C and C++ compiler (not the gcc compiler). When I build (on Solaris) the squeakvm it seems to install fine for the 32 bit. The build64 almost succeeds as well (97% compiled ok) there is an error "./squeakvm/platforms/unix/vm-sound-Sun/sqUnixSoundSun.c", line 197: identifier redeclared: sound_AvailableSpace I don't have that error in the build 32 bit. But when I launch this with an old 4.10 image it works, but with the 5.3 image I get: bash-4.4$ bin/squeak.sh Squeak5.3-19431-32bit.image This interpreter supports image formats up to 6505, cannot read file format 6521 also for 5.2 same message: bash-4.4$ bin/squeak.sh Squeak5.2-18221-32bit.image This interpreter supports image formats up to 6505, cannot read file format 6521 and for 5.0 bash-4.4$ bin/squeak.sh Squeak5.0-15120-32bit.image This interpreter supports image formats up to 6505, cannot read file format 6521 However it seems the resulted binaries (the resulting VM) that I built myself from the subversion source code can only run 4.10 or 4.6 images. for example what works is: bash-4.4$ bin/squeak.sh Squeak4.6-15102.image that launches the image correctly Is the old "unix" squeakvm able to run 5.x images at all or should one use the "opensmalltalk" VMs for that ? -- Sent from: http://forum.world.st/Squeak-Dev-f45488.html

Question about inlining | How to access named temps in FullBlockClosure?
by Marcel Taeumel 03 Apr '20

03 Apr '20

Hi Eliot, hi all! I am having issues with the inlining of #to:do: in combination with decompiling a block and accessing the temps. Here is a piece of code that works as expected: | result context | result := OrderedCollection new. (1 to: 5) do: [:each | result add: [:object | object + each]]. context := (result at: 3) outerContext. context namedTempAt: (context tempNames indexOf: 'each'). " == 3" HOWEVER, using #to:do: the result changes because code gets inlined: | result context | result := OrderedCollection new. 1 to: 5 do: [:each | result add: [:object | object + each]]. context := (result at: 3) outerContext. context namedTempAt: (context tempNames indexOf: 'each'). " == 6" What is my goal here? I want to unpack the block statement and fill in the temps. For all those [:object | object + each] in "result" I want to collect the strings: -> 'object + 1' -> 'object + 2' -> 'object + 3' -> 'object + 4' -> 'object + 5' Is there a way to access the values of temps when the block closures are created this way? Best, Marcel
