A little prototype kernel in 9 methods :)
by stepharong Dec. 14, 2016

Dec. 14, 2016

Hi guys I'm thinking to package some of my language design knowledge in a kind of book. Probably to be used to give a lecture on OOP languages. I have class-based reflective kernel. This is several years that I was thinking about prototype kernels and I decided to relax and implement one for fun over the week-end. I will probably look at mixins, traits, talents, split objects in the future. Since I cannot compile the book on jenkins, I join the pdf. Stef PS: I will finish Pharo by example now and focus on Learning OOP with Pharo. -- Using Opera's mail client: http://www.opera.com/mail/

inconsistent FileLocator behavior
by Peter Uhnak Dec. 14, 2016

Dec. 14, 2016

Hi, is there a reason why FileLocator behaves like this? FileLocator home -> FileLocator({home}) FileLocator D -> FileReference(D:\) Especially the first one (this also applies to #temp and others), is there a benefit in returning FileLocator instead of the path? Because now I always end up doing FileLocator home asFileReference, which feels superfluous. What is the use case that you don't want to resolve it yet? Thanks, Peter

REMINDER: TechTalk today, 16hs UTC. This are the links.
by Esteban Lorenzano Dec. 13, 2016

Dec. 13, 2016

Hi, Soâ¦ techtalk is today 16hs. That means: 17hs Europe 16hs UK (and no, this is not a political joke :P) 08hs San Francisco 13hs Buenos Aires 12hs Santiago (I think) â¦ and I donât know other timezones. The links we have for the meeting: youtube channel: http://www.youtube.com/user/nicopasserini/live discord: https://discord.gg/Sj2rhxn The idea is that we will try to give a live presentation and we can use the discord channel to send questions that will be solved. This is a little bit less participative than the other talks, but it was the only way we found to stream video that everybody can see (and that it remain for the future generations ;) ). cheers, Esteban

RBPattern matching dynamic array expressions
by Nicolai Hess Dec. 12, 2016

Dec. 12, 2016

Background : initial question: http://forum.world.st/RewriteTool-matching-parts-of-an-array-tp4910482.html my fix : 18910 <https://pharo.fogbugz.com/f/cases/18910/MNU-OrderedCollection-parent-when-t…> MNU: OrderedCollection>>parent: when trying to rewrite a tree with RBParseTreeRewriter the error my fix introduced :-) : 19445 <https://pharo.fogbugz.com/f/cases/19445/Pattern-code-ArrayNode-matching-fai…> Pattern code ArrayNode matching failure Question : how should a pattern with three variables (first/second/third) look like to match the expression { (1@2) . Color red . 3} and assign the (sub)-expressions 1@2 Color red 3 to the three variables first/second/third ? Looking at the initial question "RegisterRewriteTool matching parts of an array", I was suprised that for the pattern and the dynamic array expression: pattern := '{ `@first . `@second . `@third }' expression := '{ (1@2) . Color red . 3}' the third variable matches all three expressions and the first two are empty: RBPatternVariableNode(`@first)->an OrderedCollection() RBPatternVariableNode(`@second)->an OrderedCollection() RBPatternVariableNode(`@third)->an OrderedCollection(RBMessageNode((1 @ 2)) RBMessageNode(Color red) RBLiteralValueNode(3)) I fixed this in a way, that all three variables gets assigned one (sub)expression of the array. But the fix was wrong, now a statement-list-pattern-variable cannot be used anymore to match the array statements: pattern := '{ `@.stmts }'. expression:= RBParser parseExpression:'{ (1@2) . Color red . 3}'. results in an error during matching but I would expect the result: RBPatternVariableNode(`@.stmts)->an OrderedCollection(RBMessageNode((1 @ 2)) RBMessageNode(Color red) RBLiteralValueNode(3)) Now I am not sure that the pattern { `@first . `@second . `@third }' is actually a valid pattern for matching the array (sub)-expressions, the array contents is a list of three single statemts and @first isn't a statement pattern, but a pattern for an expression list. On the other hand, if I try to match *three statements* without the being in a dynamic array: (Note the missing curly braces) pattern := '`@first . `@second . `@third '. expression : parseExpression: ' (1@2) . Color red . 3'. The result works as I wanted them for the array pattern: RBPatternVariableNode(`@first)->RBMessageNode(1 @ 2) RBPatternVariableNode(`@second)->RBMessageNode(Color red) RBPatternVariableNode(`@third)->RBLiteralValueNode(3) So, is the pattern actually right or is the matching wrong? What should I expect by these patterns and expressions: pattern := '`@first . `@second . `@third '. expression : parseExpression: ' (1@2) . Color red . 3'. pattern := '`.first. `.second. `.third. '. expression := ' (1@2) . Color red . 3'. pattern := '{`.first. `.second. `.third.}'. expression := '{ (1@2) . Color red . 3}'. pattern := '{`@.all}'. expression := '{ (1@2) . Color red . 3}'. pattern := '{`@.all}'. expression := '{ (1@2) . Color red . 3}'. pattern := '`.head. `.@tail'. expression := '(1@2) . Color red . 3'. pattern := '{`.head. `.@tail}'. expression := '{(1@2) . Color red . 3}'. I would expect all statement-pattern without the dynamic array, assign the variables to the subexpressions, and the same way for the pattern with dynamic arrays. Btw, I don't know why this does not match pattern := '`.head `.@tail'. expression := '(1@2) . Color red . 3'. isn't the first variable a statement pattern ? >From the rewrite-tool documentation ( http://www.refactory.com/tools/refactoring-browser/rewrite-tool) ` recurse into the thing that is matched looking for more matches @ treat the item as a list ; used for messages where the message is treated as a list of messages in a cascade . treat the item as a statement in a sequence node # matches literals thanks in advance nicolai
