Hi James, I am not aware that I override any system methods. That would change the behavior of the base system and that is not ok. I do extend system classes though. But maybe I don’t understand your question… Christian Von: James Foster <smalltalk(a)jgfoster.net> Gesendet: Dienstag, 1.

[PDFtalk] Porting to non-namespace Smalltalks

by christian.haider＠smalltalked-visuals.com

Hi all, PDFtalk is a PDF library for VisualWorks[1]. The library has been ported successfully to Gemstone[2]. Now, there is interest from companies in a port to Squeak and VA Smalltalk.

The next step is to implement class renamings so that namespaced classes can be renamed to global prefixed names. Then PDFtalk with all its components, except for the UI, can be ported.

As its unlikely that I will be able to make it (although trying to figure out some way) - it would be neat to stay in touch with the community via something like that - even if its someone uploading some photos with captions of main talk hilites to approximate being there.

Hi Guille -- for those who cannot attend in person, please consider opening a space in https://wonder.me where we could also meet, chat and share screens very easily. It's very easy to open a space and to share with anybody -- no registration required. We could do a quick example today or whenever it suits you. https://app.wonder.me?spaceId=3a2c5046-0671-41fc-b2de-cab0af111193 On Tue, 1 Feb 2022 at 10:25, Guillermo Polito <guillermopolito(a)gmail.com> wrote: > > -------------------------------------------------------------------------------- > Pharo Days > > March 3rd and 4th, Lille, France > > https://days.pharo.org/ > ———————————————————————————————————————— > > Inscriptions are open! > > Do not miss the opportunity to meet the Pharo programming environment and > its community!
