Re: [Pharo-users] Pillar 1.1.0 released

by Johan Brichau

Hi, I just noticed that in the most recent version of Pillar, the instvar #embedded was removed from PRReference This breaks Pierâ¦ though right before this change I could make Pier3 work with Pillar just fine. The embedded var is used to specify that component references are to be embedded in the page. There are more components than Figures in Pier. I am just trying to use and work with Pier3 for Seaside book and website, so it would be great if you can consider adding the embedded variable again. thanks guys!

Search for World.st Admin

by Dimitris Chloupis

Saw this in the Squeak mailing list , but since it concerns Pharo too because World.st is the only thing close to a Pharo forum I decided to post it here too ---------- Forwarded message ---------- From: Geert Claes <geert.wl.claes(a)gmail.com> Date: 12 September 2015 at 17:40 Subject: Search for world.st admin ... Hello Smalltalkers, I am looking for someone who would like to take over all admin duties for managing the world.st i.e. The World of Smalltalk and associated online forums. I have put in significant effort in setting it all up some years ago now, especially combining all varies mailing lists on Nabble under a common Smalltalk grouping was tedious. Anyhow, I do find myself less and less engaged with Smalltalk as I am too busy with other things. I reckon ideally it should be someone who is open to all Smalltalk dialects as the idea of world.st was to inform the world about every Smalltalk flavour. The administration doesn't require a lot of effort really. The website is at the moment a simple Google Site and all forums use Nabble and the DNS record are now directly with nic.st. Sean already kindly assists in keeping the Nabble forums clean of spammers but I would now like to hand over all admin duties completely. The world.st domain name is kindly sponsored by ESUG, so it doesn't cost anything to run really. I was recently forced to change DNS server for the second time since the start as there were some issues. Paul just kindly notified me that there are once again some issues with the web presence of world.st. Soo, candidates? Feel free to forward or post the following message on what you deem to be a relevant mailing lists. Cheers, Geert

And so simple! Need to keep all those snipets somewhere. And I think the chapter in Pharo > for the enterprise does not explain well the conditional stuff in { }. P4E is still work-in-progress, no? So it still can be added there. I think we need some better way to present the content of the books than just a "book"... like with side menu showing topics within a chapter, search, or whatever. Maybe it could be made available somewhere with Guille's Ecstatic generator. Peter

Conditions are very convenient, however, to execute code during the matching part of the rewrite. Especially code with side effects ;) Thierry

Re: [Pharo-users] Modify AST to send a message on Character nodes

Hi Julien, Mark and Peter, here is a RB approach: | rewriter | rewriter := RBParseTreeRewriter new replace: ' `#aLiteral `{:node | node value isCharacter}' with: '`#aLiteral aMessage'; yourself. rewriter executeTree: (RBParser parseExpression: 'Array with: $a asciiValue with: $b with: #c with: d'). rewriter tree formattedCode And the result is: 'Array with: $a aMessage asciiValue with: $b aMessage with: #c with: d' Need to keep all those snipets somewhere. And I think the chapter in Pharo for the enterprise does not explain well the conditional stuff in { }.

It is fairly easy if you write a RB AST visitor subclass, with a single method / case to handle character literal. Now, I'm sure you can use RBParseTreeRewriter to do it with a single call...

Re: [Pharo-users] Modify AST to send a message on Character nodes

by Mark Rizun

Hi everyone, I believe you should be able to do this transformation with Rewrite Tool. The only problem I see is that you want to do this only with single symbol. Because, in my tool you can do: transform: *`#literal* into: *`#literal aMessage*. In this case `#literal means any literal, not only symbols. In other words it will transform $a into $a aMessage Also, this rule will transform, for instance 123 into 123 aMessage If I understand right, you would like to do this programatically, so you don't need RewriteTool in that case.
