Re: [Pharo-users] Mongo-BSON OID LargePositiveInteger increase

A few more comments below; I'm not seeing the things you describe when testing in my image... >> >> | id | >> id := LargePositiveInteger. >> 1 to: (16777215 + 50) do: [:each | >> id := id digitAdd: 1]. >> id. >> >> Given the comment it should overflow and the value be 50? This is not what the result is. So shall the truncation be added again or at least the comment be updated? The code will go from LargePositiveInteger to SmallInteger when overflowing from three to four bytes On which VM does it overflow to SmallInteger? I've never seen this, on the one I tested the expression in last mail, the "overflowing" digitAdd: returned a 4-byte LargePositiveInteger. >> but luckily >> >>>> #value >> ... >> replaceFrom: 1 to: 3 with: self class counterNext startingAt: 1 >> >> will even work when counterNext returns a SmallInteger.

Re: [Pharo-users] Call for feedbacks: Enterprise Pharo ePub version

by Mark Bratcher

Thanks for thinking of the e-reader users! I have a Nook Color HD, and, unfortunately, when I tried to open the eBook, it would crash on any attempt to read past the second page (which is the ToC). So clickong on a ToC link, or attempting to turn to page 3 causes the reader to simply abort. If I can think of any other diagnostic tests to try, I shall do that.

Re: [Pharo-users] Mongo-BSON OID LargePositiveInteger increase

by Henrik Johansen

Hi Holger, sorry, I'm not good at responding to unsorted email in a timely manner :/ The comment is inaccurate, the wraparound relates to how the number is used in OID >> #initialize, not the number itself. lp := LargePositiveInteger new: 3. lp at: 1 put: 255; at: 2 put: 255; at: 3 put: 255. lp := lp digitAdd: 1. (ByteArray new: 3) replaceFrom: 1 to: 3 with: lp startingAt: 1; yourself So the number will keep on growing, but for the purposes of our use, it wraps around.

Good idea, I will have a look at this feature. :-) Julien On 30/05/16 17:07, Denis Kudriashov wrote: > Nice. > > And it would be much nicer if Pharo allows to install it as new > notifications backend (instead of morphic one). > > 2016-05-30 16:50 GMT+02:00 Julien Delplanque <julien(a)tamere.eu>: > >> Hello, >> >> I took the libnotify [0] binding for Squeak [1], adapted it to use the >> Pharo UFFI API and >> enhanced it.

Nice. And it would be much nicer if Pharo allows to install it as new notifications backend (instead of morphic one). 2016-05-30 16:50 GMT+02:00 Julien Delplanque <julien(a)tamere.eu>: > Hello, > > I took the libnotify [0] binding for Squeak [1], adapted it to use the > Pharo UFFI API and > enhanced it.

[ANN] LibnotifyBinding: a binding to libnotify 0.7.6 for Pharo

by Julien Delplanque

Hello, I took the libnotify [0] binding for Squeak [1], adapted it to use the Pharo UFFI API and enhanced it. It is available here [2] and seems to work well (see attached image). It does not cover all libnotify possibilities (see the README on github) but it is already usable to display notifications with eventually icons, set urgency, set timeout, etc... It was great to try UFFI, it is really easy to use. Thanks a lot for it! :-) Regards, Julien Links: [0]: https://developer.gnome.org/libnotify/ [1]: http://www.squeaksource.com/libnotify.html [2]: https://github.com/juliendelplanque/LibnotifyBinding
