Re: [Pharo-users] PostgresV2 Driver available?

by Jan BlizniÄenko

Hello, actually, I do, although not with Garage or Glorp. I am not sure how exactly is related version in https://github.com/pharo-rdbms/garage and the one on deprecated.smalltalkhub.com/#!/~PharoExtras/PostgresV2 , but I migrated the smalltalkhub one to https://github.com/JanBliznicenko/PostgresV2 and updated dependencies for my own purposes. It might be, however, actually even older than the one in garage repository. Best regards, Jan Esteban A.

how to structure this project

by Roelof Wobben

Hello, I want to make my first app with seaside and a database, as database I use Postgres with the P3 driver of Glorp. So I have a class Customer with the instance variables. AndÂ I have a Descriptorclass which takes care of the database. AndÂ I want to make a class which holds the layout. But now I wonder ifÂ I want to make a function that adds a customer from a form. Or a page where I display all customersÂ or details of a customer. Do I have to place them in the database layer and call that function or can I use the customer class for that. Regards, Roelof

Re: [Pharo-users] pharo books as audiobooks

by Siemen Baader

Hi Marek, Thanks for the pointer. This is useful and interesting, but I wasn't clear enough - I need the audio on my mobile phone and it needs to bookmark where I left off, like audio book players and podcast apps do. Pocket has a very nice workflow for this because I can bookmark a web site in Firefox, then play back on mobile later. I've also used http://talkify.net and saved the whole .mp3 file as an audio book to my mobile device, but talkify and Pocket only work with HTML accessible over http via a public URL. But thanks, and I'll probably learn something from this tool as well. Besides - another reason why it would be cool if http://books.pharo.org had supplementary HTML builds with unique anchors for chapters and sections because this makes it very easy to point to specific sections in the books when answering questions on the mailing list. cheers, Siemen On Fri, Aug 28, 2020 at 12:37 PM niepiekm <niepiekm(a)gmail.com> wrote: > Hi Siemen, all, > > you may listen to PDF files from the Web via 'Read Aloud' Chrome extension > ( > https://chrome.google.com/webstore/detail/read-aloud-a-text-to-spee/hdhinad… > ) > and use its service at > https://assets.lsdsoftware.com/read-aloud/page-scripts/pdf-upload.html to > open and listen to local PDF files. > > Simply open a local PDF file via the service and click on the extension > button. > > Regards, > Marek > > > > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html > >
