Hello, from what I remember, this would require porting the pdf lib of christian as Values one of the underlying framework.

Stale SQLite connection
by Jeff Gray March 16, 2020

March 16, 2020

In my code I'm opening a sqlite connection and keeping it open rather than opening and closing one on each transaction. Generally it's working well. I often save and close my image. When I then reopen the image I still have a connection and it says it's open, but using it gives me an error. This is easily recovered. I just open a new connection. Is there a way I can see if a connection is still good, in my code? Or should I be opening and closing connections every transaction? I haven't benchmarked it but I'm assuming it would be slower. I guess I could set my connection to nil in a start-up script. That would cause my code to get a new connection after a break from development. Any recommendations? Thanks, Jeff. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Thx! Some controls in the playground inspector are not reacting, like I and O. Before there were some small controls in it. I can use the scrollwheel but sill wondered.

Hola, Here is a script, for which I hope some of you will find useful. The script of today visualize the number of infected and allows for an easily (and very basic) comparison. First, you need Roassal3 and DataFrame. Here is the code: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Metacello new baseline: 'Roassal3'; repository: 'github://ObjectProfile/Roassal3'; load. Metacello new baseline: 'DataFrame'; repository: 'github://PolyMathOrg/DataFrame:v2.0/src'; load. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Then, evaluate the Pharo code available on: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= https://gist.github.com/bergel/6ebcde9696ef922f2b519c56a4520bac -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= You should then see the following: Change the names of the countries to see what you are interested in.

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 transformation for Pharo Regards, Esteban A.
