Re: [Pharo-users] RewriteTool matching parts of an array

by Mark Rizun

Hi Peter, I tried to perform this transformation with RewriteTool and got the same DNU. > However when I tried to execute it I was met with DNU > OrderedCollection>>parent: > > It seems that the @first/@second part are not matched properly. > Actually they are matched properly, because if you try to put in transformation part, for example, {``@first.``@second} everything works fine. > Any way to fix this? Or am I doing it wrong? > I believe you are doing everything just fine. However, it is definately the problem of RBParseTreeRewriter or something related to it. Try to execute following code in playground and you will get the same DNU: | rewriter | rewriter := RBParseTreeRewriter new replace: '| base | base := {(#Department -> {``@first. ``@second})}' with: '| base | base := {#Department -> (Array with: ``@first with: ``@second)}'. (rewriter executeTree: (RBParser parseRewriteExpression: '| base | base := {(#Department -> {(1 @ 255). (Color lightMagenta)})}')) ifTrue: [ rewriter tree asString inspect ]. This code does exactly the same that RewriteTool should do when you put all the parts into it. Thus, I think, it is not a problem with the tool. Cheers, Mark

Pharo on a Mac

by Bart Venckeleer

Hi all, 20 years ago I wrote an application in SmallTalk-V that I'm porting now to Pharo since Smalltalk-V doesn't run 64-bit systems. I run Pharo on a Mac and what I experience is a bit annoying and I hope one of you already solved the issues. In fact there are two things that bother me: 1. The typical cursor navigation doesn't work. Normally on a Mac: cmd <left arrow> moves the cursor to the beginning of a line, cmd <right arrow> moves the cursor to the end of the line, option <left arrow> moves the cursor one word to the left, option <right arrow> moves the cursor one word to the right, ... and of course it can be combined with shift to make selections. In Pharo I can't do that and it slows down coding. 2. There are problems with the Magic Mouse and it is very annoying when browsing code. Whenever you touch the mouse surface to scroll horizontally it generates shift <left arrow> or shift <right arrow> events which causes text to be selected without it being the intension. Is there a solution for this? Thanks for helping me :-) Cheers, Bart -- View this message in context: http://forum.world.st/Pharo-on-a-Mac-tp4910484.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

RewriteTool matching parts of an array

by Peter UhnÃ¡k

Hi, I wanted to use RewriteTool to rewrite dynamic arrays Source AST: | base | base := {#Department -> {710 @ 255. Color lightMagenta}} matching AST: | base | base := {#Department -> {``@first. ``@second}} transformation: | base | base := {#Department -> (Array with: ``@first with: ``@second)} However when I tried to execute it I was met with DNU OrderedCollection>>parent: It seems that the @first/@second part are not matched properly. Any way to fix this? Or am I doing it wrong? Thanks, Peter
