Does anyone know Spec?
by Steve Quezadas June 3, 2019

June 3, 2019

I created a simple listbox. It looks like this: https://s3.amazonaws.com/steverstuff/items.png If I hit a specific selection, say "Item B", how can I make smalltalk run an arbitrary piece of code? (ie: "Transcript show: 'got here'"). Method "whenSelectedItemChanged" should, in theory, do this. It is mentioned in the [[ https://benjamin.vanryseghem.com/projects/spec/docs/example/#protocolList][…]] tutorial, but for some reason it's not executing. Did a new verion of spec change things since the documentation was written? There doesn't seem to be a spec community where I can ask the question.

Find after in strings?
by Tim Mackinnon June 3, 2019

June 3, 2019

Maybe this is a dumb question - and often Iâm surprised when asking these, but why is there no way to âfind afterâ a string. I find it rather boring to try and parse a string, after a known marker - thus: (loc := aString findString: âmarkerâ) > 0 ifTrue: [ loc := loc + âmarkerâ size ]. Is there a better way? This whole pattern seems very old and clunky and not smalltalk like? Couldnât we have: findAfter: aString ifAbsent: aBlock ? Or is there a whole better pattern for string searching that Iâm missing ?

Finder blows me away again
by Ben Coman May 31, 2019

May 31, 2019

Just sharing... I wondered if there was a better way of converting an array of strings into one string than doing this... x := #( '++' '||' '++') . x flatCollect: [ :c | c ] but it was awkward copying the array twice into Finder. So I wondered if it could do variable assignment, and it can!! i.e... Tools > Finder > Examples > then simply paste the above snippet into the textfield. cheers -ben

[gemstones] Use case for GsDevKit_home
by sergio ruiz May 30, 2019

May 30, 2019

I have another project coming up, and I have free reign over the tech stack. I am gonna use Pharo, but I'd like to spend my up front time on this project figuring out the things I usually wait until the end to do. One of these issues is setting up gemstones. I would like to use GsDevKit_home, but I want to make sure that the use case I am envisioning is in keeping what this package is set up to do. My vision is something like: - Deploy a stone to remote production server. - Develop in the latest version of Pharo on my local machine, keeping my project in git. - When it's time to deploy, use tODE client to tell the production server to grab the latest code, and we're done. Does this sound reasonable? Also, one thing that I find invaluable in troubleshooting applications written using relational databases is to be able to be able to just dump the production database and load it up on my local machine. Is this possible using gemstones?

[GsDevKit_home] Is this project still the way to set up Gemstone?
by sergio ruiz May 30, 2019

May 30, 2019

I am spending some time learning how gemstone works, and using this project as a starting point. When trying to create a stone using either 3.3.0 or 3.4.0, I get the following error at the very end. This is using the following incantation: createStone devKit_33 3.3.0 |& tee -a $GS_HOME/install.log Error on or near line 99 :: devKitCommandLine startstone devKit_33 -N :: devKitCommandLine startstone devKit_33 -N Error on or near line 116 :: startStone -b -N devKit_33 :: startStone -b -N devKit_33 Error on or near line 148 :: newExtent -s /Users/sergio/Sites/GsDevKit_home/server/stones/devKit_33/product/bin/extent0.seaside.dbf devKit_33 :: newExtent -s /Users/sergio/Sites/GsDevKit_home/server/stones/devKit_33/product/bin/extent0.seaside.dbf devKit_33 Error on or near line 209 :: createStone devKit_33 3.3.0 :: createStone devKit_33 3.3.0 Ideas?

Morphic question
by Markus Stumptner May 29, 2019

May 29, 2019

Years ago, I asked a Morphic question here and in response was kindly provided with the code snippet at the bottom, which I puttered around with and it eventually led me to puttingsome useful functionality together, so thanks again.Â I came across again now and as I played around with it, there is a question that I can't work out, silly as it may seem: in the example, the circle shows standard drag-and-drop behaviour, while the orange Morph "sticks" to the mouse once clicked and has to be clicked again to be dropped off.Â I could not work out where (i.e., which method) that difference in behaviour comes from. It's not due to the order of processing; adding the CircleMorph second doesn't change things. Any ideas? Notably, when I run the #exampleCircleMorph class method, the CircleMorph that opens on the screen does not show this behaviour, it "sticks" to the mouse in the same way as the orange Morph. FWIW, this is Pharo 6 under Windows (7 or 10 makes no difference). | window pane board background scaler| background := AlphaImageMorph withForm: (ZnEasy getJpeg: 'http://i.imgur.com/K1QR9vA.jpg'). background lock. board := PasteUpMorph new. board color: Color gray; borderWidth: 3; borderColor: Color black; extent: background extent; backgroundMorph: background; addMorph: (CircleMorph new color: Color cyan; position: 41@23; yourself); addMorph: (Morph new color: Color orange; position: 1200@1200; yourself). scaler := TransformMorph new. scaler extent: background extent * 0.5. scaler scale: 0.5(a)0.5. scaler addMorph: board. pane := ScrollPane new. pane scroller addMorph: scaler. window := pane openInWindow. window position: 20@20; extent: 420@420.

Pharo 7.0.3 Seaside 3
by Jeff Gray May 26, 2019

May 26, 2019

Hey all, Apologies if this one has been done to death. I am on windows 10. Just downloaded a fresh image, 7.0.3 and tried loading Seaside 3 from the catalogue browser. I get the 'Seaside 3 has not been marked as tested for Pharo 7.0.3' dialog but press Yes to continue. It looks like it starts to load packages (I get a progress bar flashing up) but then Pharo just closes. I can't see any error log. Is there another way to load Seaside or do I just need to wait for Seaside testing to complete? Thanks. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

TelePharo / Seamless Bitmaps are all 0s
by Alistair Grant May 25, 2019

May 25, 2019

Hi Denis, If I print: remotePharo evaluate: [ Array withAll: #(42 42 42) ] "==> #(42 42 42)" which is obviously correct, but: remotePharo evaluate: [ Bitmap withAll: #(42 42 42) ] gives me a bitmap with all zeroes (running it locally does the expected thing). I can see that the bitmap is being created correctly on the server, but by the time it gets back the values have been lost (all converted to 0s). If I change the Bitmap>>seamlessDefaultTransferStrategy for the Bitmap to #defaultByReference I can correctly access the values (just for debugging, by reference isn't practical for the real system). Any hints on where to look? Thanks again, Alistair
