inquiring question about ifTrue: implementation
by Petr Fischer March 19, 2018

March 19, 2018

Hello, I have some sort of philosophical question about ifTrue:/ifFalse: implementation. Now, ifTrue: is defined in the Boolean class (subclassResponsibility) + in True and False classes, so, we can send this message to the boolean expressions (instances) only, otherwise DND occurs. But we can also define one universal ifTrue: right in the Object class, in this style: Object>>ifTrue: .... (self = true) ifTrue: [ ... ]. then, we can send ifTrue: message to ANY object and it will work correctly without DND exception on non-boolean objects. Is something bad about this idea? Thanks! pf

Disabling GTSpotter dive in
by Peter UhnÃ¡k March 19, 2018

March 19, 2018

Hi, is it possible to disable GTSpotter dive in functionality when the result would be empty? I've tried looking at GTSpotterStep>>canDiveIn: but it seems that no matter what there will be at least one processor (at least the "parent" one, which is weird). Also there are two spotter extensions directly on Object (Pharo 6.1) * spotterForRenderingShapesFor: * spotterRePropertiesFor: which are always applied... but canDiveIn: was returing true even when I disabled them. Thanks, Peter

confusion about GTFilter hierarchy and GTFilterSubstring
by Peter UhnÃ¡k March 16, 2018

March 16, 2018

Hi, what exactly is GTFilterSubstring for? The observed behavior is identical whether I use it in my spotter method or not. (As I don't know what exactly it does it's hard to observe it in the first place...) Also as none of the concrete classes in the GTFilter hierarchy have comments it's hard to guess what is their respective difference/value. Thanks, Peter

Re: [Pharo-users] Ever growing image

While bootstrapping seems a clear choice for building images. A tool could then scan an image (e.g. for deployment) and pare it down to just what's needed. IIRC Self might have done some work in this directionâ¦ ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Packaging question
by Stephane Ducasse March 16, 2018

March 16, 2018

Hi I'm developing a small library named Chrysal (to be announced when ready - the successor of Cocoon) that supports configuration files (and conversion of strings into our lovely objects). The idea is that based on description objects, a class is generated statically with all the conversion logic. Now a configuration for an App is a subclass of one minimal class called ChrysalConfiguration. and this class is packaged into the ChrysalRuntime package this is the only thing needed (I could remove it by automatically recompiling even more code but looks a bit terrible at the end). Now my question. Should I propose two BaselineOfs? One for the Generator and one for the Runtime? I thought so. And generator should depend on the runtime. Stef

Pillar7 Markdown export
by Arturo Zambrano March 16, 2018

March 16, 2018

Hi, I think a found a bug (more details in the screenshot bellow) in pillar7 export. Adding a canvas newLine to the PRMarkdownWriter>>visitParagraph method seems to fix that... Should I fork Pillar7 branch and make a PR in github? Thanks Arturo

Something is happening...
by Marcus Denker March 15, 2018

March 15, 2018

Hi, There is something odd happeningâ¦ or better: There is *a lot* happening. Just one example: for the Newsletter, the original idea was to send out once a month a post with 3 things, some of them recycled (e.g. pointers to existing projects, re-use âsuccess storiesâ, things like that. Now already some months ago I had to add âand here are some other interesting announcements, blog posts, videosâ. But this month, the list of things for the newsletter TODO list contains over 60 entries. With the exception of maybe 5, these are just things that happened between sending the February newsletter and today. Newsletter March should be ready till this thursday, I hope, subscribe or read the oder ones here: http://newsletter.pharo.org <http://newsletter.pharo.org/> Marcus
