Re: [Pharo-users] FFI and absolute path to dll

by ASAM

Thanks for the tips. It really helped me a lot. The dll is now loaded (I chose the 64-bit version of the dll). I am currently working on value mashalling and I want to create an ENUM class subclass from FFIEnumeration. Inside http://books.pharo.org/booklet-uffi/pdf/2020-02-12-uFFI-V1.0.1 i read chapter 4.4 Enumerations. I tried the example. For me, however, only new class variables are created after "ExampleEnumeration initialize". Is that okay? or a bug? In Doc..."You will see that the enumeration class gets redefined as follows creating and initializing a class variable for each of its elements." but i can't see the initializing. Do I have a mistake in thinking? Thanks for your help and time. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Willow affordance setValueTo etc

by Gabriel Cotelli

Hi Tomaz, Just from my memory try: renderContentOn: html | aText aButton | aText := self componentSupplier singleLineTextFieldApplying: [ :theField | ]. aText identifyIn: html; changeContentsTo: 'Some text'. aButton := self componentSupplier asynchronicButtonLabeled: 'Click me' applying: [ :theButton | ]. aButton onTrigger setValueTo: 'Some other text' thenTriggerChangeOf: aText. We're trying to self-identify components when needed, so you can raise an issue on the issue tracker and we can see if this case can be automatically handled.

Willow affordance setValueTo etc

by TomaÅ¾ Turk

Dear all, I'm playing with Willow and found it very useful for setting the web design, however, I have some challenges with understanding the interaction affordances. They are nicely described in the documentation - although somewhat cryptic. For instance, I cannot successfully set up the #setValueTo:thenTriggerChangeOf: "directly" on the TextField like in this example, where I'd like to set the text of aText to 'Some other text' after the button aButton is clicked: renderContentOn: html | aText aButton | aText := self componentSupplier singleLineTextFieldApplying: [ :theField | ]. aText changeContentsTo: 'Some text'. aButton := self componentSupplier asynchronicButtonLabeled: 'Click me' applying: [ :theButton | ]. aButton onTrigger setValueTo: 'Some other text' thenTriggerChangeOf: aText. The web browser reports 500 Internal server error with The identifier was never assigned. It is mentioned in the docs that IdentifiedWebView should be used to guarantee the id, however I cannot get it to work. As I understand, #serialize; #setValueTo: can be used instead of #serialize; #evaluate: ; #render affordances to get the data from the browser, inspect it and sending it back to the browser - or should #determineBehaviorByEvaluating always be used for that purpose? Thanks, Tomaz

Spec2 Pharo8/9; icons

by TomaÅ¾ Turk

Dear all, What would be the best Pharo version to start building a Spec2 GUI for an app - Pharo 9 which is under development but with novelties in Spec2, or Pharo 8? What's the best (easiest ...) way to import new icons into Smalltalk ui icons? Is there any special bitmap format to be considered? Thanks and best wishes, Tomaz

But I recommend to not have running servers/services in the saved image, but instead to save (better auto build) a new clean image with nothing open (close all windows), nothing running, just your code. And then use a startup script. Either use a run.st file which does all the work, or a class side 'MyStart startForProduction'.

Also use 64-bit (that is 64-bit Pharo on 64-bit Linux), it will make your life much easier.

Re: [Pharo-users] running Pharo8 in Digitalocean

by Sven Van Caekenberghe

Hi, Everybody is free to do whatever they want, of course. My advice would be to not use graphical tools to deploy server applications (unless as add ons afterwards, like a dashboard or management app). Use Linux (Ubuntu is the safest choice). Stick with headless (no gui) command line tools. Pharo is very good at this. The following book chapter explain things reasonably well: https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… Nowadays, you would use Baselines and git though. I can give you more info if you want. Feel free to ask questions.
