Xtreams in Pharo 3
by Sven Van Caekenberghe Nov. 23, 2013

Nov. 23, 2013

Hi, This evening I tried to load Nicolas Cellierâs Xtreams (http://www.squeaksource.com/Xtreams/) into Pharo #30582. This went almost flawless ! I went for ConfigurationOfXtreams project bleedingEdge load. which loaded a MetacelloFetchingMCSpecLoader(linear load : linear load : 1.3-baseline [ConfigurationOfXtreams] load : Xtreams-Support-nice.11 load : Xtreams-Core-nice.20 load : Xtreams-Terminals-nice.31 load : Xtreams-Transforms-nice.23 load : Xtreams-Substreams-nice.19 load : Xtreams-CoreTests-nice.20 load : Xtreams-TerminalsTests-nice.17 load : Xtreams-TransformsTests-nice.14 load : Xtreams-SubstreamsTests-nice.13 load : Xtreams-Parsing-cwp.6 load : Xtreams-ParsingTests-cwp.5 load : Xtreams-TerminalsFileSystem-nice.3 load : Xtreams-TerminalsFileSystemTests-nice.2) There is one Undeclared in XTReadStream>>#detect: (NotFoundError should be NotFound in Pharo). Unit tests passed, except for the PEGParser related ones, most probably because Opal optimises #timesRepeat: which is overridden in PEGInfinity, I am not sure how this should be fixed, maybe with an Opal compiler directive somewhere ? Running the tests resulted in some external semaphore warnings in the Transcript. I also loaded Nicolasâ new #legacy layer (Xtreams-LegacyStreamAPI-nice.1), Iâll have to study that, it sure looks interesting. In any case: great work, thanks Nicolas ! Sven

How to use Opal for parsing peace of code?
by Juraj Kubelka Nov. 23, 2013

Nov. 23, 2013

Hi! I am interested how to use Opal for parsing peace of code. I have supposed to use something like this: | root node1 node2 | root := OpalCompiler new source: 'Color blue yourself'; useFaultyForParsing: true; parse. root doSemanticAnalysis. node1 := root bestNodeFor: (2 to: 2). node2 := root bestNodeFor: (7 to: 7). But node1 is a RBMethodNode, and node2 is a RBVariableNode. Does it matter if source for OpalCompiler is peace of code or method source? Thank you, Jura

is this ok?

in the debugger: stepToSendOrReturn "Simulate the execution of bytecodes until either sending a message or returning a value to the receiver (that is, until switching contexts)." | context | [ self willSend or: [ self willReturn or: [ self willStore ] ] ] whileFalse: [ context := self step. context == self ifFalse: [ self halt. "<========================= THIS" "Caused by mustBeBoolean handling" ^context ]] so... the halt is ok there? cheers, Esteban

"Should not happen" in Slot
by Torsten Bergmann Nov. 22, 2013

We can mark methods with pragmas - but there is no way for classes. Adding a new instance variable "annotations" to ClassDescription in Pharo 30#30590 leads to an error "Should not happen" (in Slots code). Any help appreciated... Thx T.
