FontSubstitutionDuringLoading -> MissingFont?
by Frank Shearar 30 Nov '13

30 Nov '13

One way in which Graphics depends on System is through the resumable exception FontSubstitutionDuringLoading. StrikeFont class >> #familyName:size: uses it to signal that a font family is missing, and ProjectLoading uses it to record missing fonts. The relationship is entirely reasonable, but problematic from a module point of view: it entangles a low level package (Graphics) with a mid- to high-level package (System). I propose the following: * rename FontSubstitutionDuringLoading to MissingFont. * Update the three references to MissingFont. * move MissingFont to Graphics. This preserves the behaviour, but suggests what the problem is rather than under what circumstances the problem appears. More importantly though, it means that Graphics depends that much less on System. Thoughts? (This has the side effect of removing the problems that I reported yesterday regarding not being able to see all users of FontSubstitutionDuringLoading - the new MissingFont literals are all ClassBindings. However, note that during the class rename I didn't see all the places I needed to change, presumably because of the Alias/ClassBinding discrepancy.) frank

To the instruction parsing ability of InstructionStream I add the actual semantics for execution. The execution state is stored in the indexable fields of my subclasses. This includes temporary variables and a stack of values used in evaluating expressions. The actual semantics of execution can be found in my category "system simulation" and "instruction decode". These methods exactly parallel the operation of the Smalltalk machine itself. The simulator is a group of my methods that do what the Smalltalk interpreter does: execute Smalltalk bytecodes. By adding code to the simulator, you may take statistics on the running of Smalltalk methods. For example, Transcript show: (ContextPart runSimulated: [3 factorial]) printString.!

A Bounty for CMake-ifying stack/Cog vm build process
by tim Rowledge 30 Nov '13

30 Nov '13

Want to make $1000.00 (that’s one thousand USD in case I mistyped the number of zeros) and be a hero? I’m seriously not interested in delving into the insanity of either automake nor cmake; my experiences thus far have left scars. So, in order to avoid pain whilst getting a Cog/stackvm build system that gets reasonably close to that in place for the plain interpreter (see squeakvm.org) - with a side aim of eventually merging - I am offering some money. For someone that actually knows this stuff I suspect it is an easy, if perhaps long-winded, job. The acceptance test that determines when payment can be made would be a) Eliot & Ian agreeing that it is good enough to replace the auto-blargh horror that is currently in use (that’s a pretty high bar) and b) successful addition of the Raspberry Pi faster-blt code to the cog/stack build, as with the current plain interpreter build tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Useful Latin Phrases:- Canis meus id comedit = My dog ate it.
