Permancy of booklet links

by Ben Coman

This link turned up in a google search on... Web Scraping Pharo, which is great, http://files.pharo.org/books-pdfs/booklet-Scraping/2017-09-29-scrapingbook.… but with the date I'm wondering how permanent the link is, for if I use it the respond to someone's question in a forum? Will you be keeping years of pdfs? For now I'll just use the directory url, but future missing files will frustrate user searches. Perhaps a sitemap is needed (though I'm not familiar with the details)... https://support.google.com/webmasters/answer/183668?hl=en cheers -ben

Re: [Pharo-users] Pharo: Reinventing Smalltalk

by Andrew Glynn

There is a basic difference between debugging compiled code using debug symbols, debugging a live environment thatâs represented as if it isnât, and debugging a live environment thatâs represented as if it is. In general Java is represented the same way as C/C++, although Eclipse is somewhat better than other Java IDEâs when it comes to debugging, mainly because it tries to be somewhat like VisualAge for Java, which was written in Smalltalk. XCode represents MacOS similarly to the way Eclipse represents Java. F-Script, on the other hand, allows you to debug MacOS / iOS in the same manner Smalltalk environments do. But then, F-Script is Smalltalk by any other name.

Re: [Pharo-users] Writing "powerpoint" like presentations in Pharo?

by Dimitris Chloupis

Well if you have a specific template in mind then you can use Pillar and input the final results as images back to Morphic. Creating a full PowerPoint implementation with Morphic sounds an overkill to me. Why waste all this time when there so many great external solutions ? Or you even bypass Pillar and go straight to a PowerPoint app, export to jpgs and import to Morphic. Definetly not more than 2 hours work.

Watching is one thing you can do to see the result of an expression. The issue is that this has to be in scope within the selected stackframe or something. I can never watch once that scope has gone. As a result, I have no idea if it is possible, but I cannot just open an inspector that sticks around as I process stacks in the debugger. That level of the environment being alive is just missing from the Java development environments. One reason is Smalltalk is running the image objects all the time and Java does not have an image-based environment. You restart the environment each time you rerun a java test case. It's DOA. - HH > -------- Original Message -------- > Subject: Re: [Pharo-users] Pharo: Reinventing Smalltalk > Local Time: November 1, 2017 7:27 PM > UTC Time: November 1, 2017 11:27 PM > From: kilon.alios(a)gmail.com > To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org>, henry <henry(a)callistohouse.club> > > Should pretty standard even for Java using a debugger > > I mean I have done this with Visual Studio and its debugger with C++.

Re: [Pharo-users] Writing "powerpoint" like presentations in Pharo?

by Tim Mackinnon

Yes I was thinking of something like the morphic approach with a palette for adding buttons, text, images (maybe someone has done a simple vector paint app - didn't think to check). Of course it quickly gets annoying without a simple template mechanism to have a consistent header/footer - and you also need to try it on a projector and make sure it actually looks right... and so it will take longer than a few hours is my fear (my morphic is a bit rusty too). Not a horrible amount of work - but I actually need to create my slides and demo so may be a longer term project unless someone has already done it.
