[Pharo-project] How to deliver real-time web and mobile applications?

by sebastian＠flowingconcept.com

Hi guys, this is a converstation starter to this genuine question: How to deliver real-time web and mobile applications? ...that can also smoothly work offline and online? I know, itâs annoyingly pretentious, but... (a) what else would make sense? and (b) sounds like the world will (see examples below) (c) what chances we have to achieve it if we donât even aim to it? So do we really have an alternative? ...continues here: http://sebastianconcept.com/brandIt/how-to-deliver-realtime-web-and-mobile-… I really want to hear your opinion on this sebastian o/

I look at code. Nice design. Good tests. When I experimented with my implementation (very little) I also introduced cursor object which was responsible for moving, inserting and deletion characters and holds position in text. I stop my experiment when I start think about text layout and how it can influence "cursor behaviour". You have #moveDown method to move cursor down to next line. But how you consider implement this for "visual text lines" which created by text layout without CR separator? Do you consider rebuild TextModel instance when text bounds will changed? (to reflect visual lines state). Same questions about text selection. How to track selection positions when text bounds changed and it influence visual lines state?

Yes, the singular forms should return the same as the plural ones, that is the only thing that makes sense.

[Pharo-project] 1/2 hour

by Torsten Bergmann

Looks like we created two issues: #6876 (Camillo) and #6877 (me). Joe Rickerby wrote >I'd be very happy if hour just returned the same as hours. I already provided a fix with a test case specific to the problem with #hour, see the changeset at (was not able to upload a slice for whatever reason). Details in https://code.google.com/p/pharo/issues/detail?id=6877 It will come with one of the next updates. If you need it now just file in the changeset. Since the same problem is for other messages like #week too we should keep the other issue #6876 from Camillo open https://code.google.com/p/pharo/issues/detail?id=6876 until we have time to fix this as well. Bye T.

Gofer it squeaksource: 'Athens'; package: 'ConfigurationOfAthens'; load. ConfigurationOfAthens project lastVersion load.
