Re: [Pharo-users] How to catch and handle multiple exceptions

Richard, I was going to comment the #when:do:[when:do:] approach of VAST [1]. Why do you say it won't be fast? Because of the multiple exception handlers in the call stack? I think that some construct might be used to obtain the same as the #when:do:when:do: but using a chained approach instead.

Follow up. Seems that playing with these COM/ADO objects in the playground messes with the VM; so I'm getting weird image crashes, where the image closes without any notice. Do you experience the same? Esteban A. Maringolo On Wed, Mar 11, 2020 at 4:11 PM Esteban Maringolo wrote: >

Re: [Pharo-users] Any existing RDF implementation in Pharo?

Hi Juraj, There is an RDF project in Cincom's Public Repository for VW. And there it seems somebody was wanting to migrate it to Pharo since there is a "RDF fileout Pharo" package whose first version says: --- Blessed: Work In Progress --- By: chaider --- On 25/08/2019 08:20:42 started the RDF t

Re: [Pharo-users] How should XMLHTMLParser handle strange HTML?

Hi Peter, Just in case it helps you parsing the files... I had to parse HTML with a XMLParser (no XMLHTMLParser) so what I did was to pass it first through html tidy [1] converting it to xhtml which is compatible with XML parsers (it is XML, after all). Regards, [1] http://www.html-tidy.org/

[Pharo-users] Preserving Pharo Window state between sessions

Is there a way to preserve the window state after saving the image on quit and restarting it again? If I save my image window maximized I would like it to be maximized when starting again. Having it otherwise can be annoying when moving from different screen resolutions, because a 1920x1080 maxim

I don't know what is behind the poll system, but it doesn't work in Brave browser. It simply says "Thanks for participating in the poll." I find the questions confusing though. Esteban A. Maringolo On Wed, May 13, 2020 at 4:43 PM Richard Kenneth Eng wrote: > > https://smalltalk.tech.blog/2020/0

Re: [Pharo-users] a simple question (I think)

Objects interact with each other by sending messages, although you can get the sender by using reflection (thisContext sender), it is not a common practice to do so. So if you need another object to know the sender (or any other object) you simply pass it as a parameter. So modifying your example,

In my case it didn't let me vote at all, it assumed I already voted. I started a private tab, disabled tracking (it tracks a lot for a single post), and then saw the options, and there wasn't a "none of the above/other" kind of option. So I didn't vote. Esteban A. Maringolo On Fri, Jun 19, 2020

Hi, The "class vs instance" side is one of the most confusing things for newcomers, I remember struggling with it when I learnt Smalltalk (and also was a novice in OOP). It helps you thinking it this way: the instance side is everything that will affect all instances of such class, and you can th
