Mini Pharo -> JavaScript translator?
by Alexandre Bergel March 15, 2017

March 15, 2017

Hi! Is there a simple way to translate Pharo code into Javascript? There is Pharo JS, but I cannot load it in Pharo 6. There is the amber compiler, but I cannot find a version for Pharo. Amber takes the approach of translating everything into JavaScript, including the Smalltalk object model. While this is great for fan of bootstrapping images, it produces large javascript code. Is there a kind of Slang for JavaScript? I am looking for something minimal. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

programmatic use of the language compiler
by Raffaello Giulietti March 15, 2017

March 15, 2017

Hi, I'm wondering how to programmatically compile a method. I tried using a variant of ClassDescription>>compile:*:notifying: However, on a method with undeclared variables, when the Transcript is open there seems to be no way to avoid a message being written there. Further, the requestor passed as a notifier in the above method is not even notified when the compilation context is not interactive. What is the correct way to use the compiler programmatically and in a non interactive batch, still being able to catch all the compilation errors and warnings? Thanks Raffaello

Re: [Pharo-users] New Version of Pillar on Windows
by mldavis＠chaparralwest.com March 15, 2017

March 15, 2017

Hello Steph, Thank you and those that helped me on both Slack and Discord. This turned out to be an obsolescence issue! Mine and the April 2016 edition of Enterprise Pharo which I was using!!! Once I was pointed in the right direction, to the most recent edition of the book, everything I needed was there. Don't you just love newbies. :>} . You all have created a great learning environment and resources, not to mention evolving the most pleasant rendition of the SmallTalk environment I've ever seen. Thank you. Mike p.s. (post script): "You all" is the Southern U.S. English plural of "you" for those who haven't heard it before. Don't adopt it though, it is only a dialect ;>}. Hi mike Was it working before? I will check on the HTML case (now) because I'm checked the mooc and the book. > I am trying out the new version of Pillar (build 1940 or 1941) on > Windows on Pharo 50770, following the Pillar tutorial in Enterprise > Pharo book: > I created the new file first.pillar containing: !

small user experience behavior
by Raffaello Giulietti March 15, 2017

March 15, 2017

Hi, here's a situation I'm facing quite often: I'm reading the code of a method in the browser and need to see how the method with the same selector looks like in another class (in particular, in the same class hierarchy). In some IDEs, it's simply a matter of selecting another class. If such a method exists, it is displayed. Not so in Pharo: clicking on a class always displays its definition. Is there a way to get this behavior? Greetings Raffaello

Roassal IdentityGroup regression?
by Peter Uhnak March 13, 2017

March 13, 2017

Hi, apparently there used to be RTIdentityGroup (and Collection>>asIdentityGroup) in Rossal, but I can't find any mention of it http://forum.world.st/AST-visualization-with-Roassal-td4840243.html did it vanish on its own (bug) or was that a deliberate choice (feature)? Peter
