Re: [Pharo-dev] The Dilemma: Building a Futuristic GUI for Ephestos

by kilon alios

Plenty ? no A few ? yes Woden is certainly a project that I want it to be successful and keep going forward but at the moment I can't say its usable when each time I resize the window it corrupts the viewport. No offense intended but lately the more I dive inside Pharo the more I feel I waste my time, I love the IDE and the environment and live coding but using the libraries is a never ending struggle for me. I agree with Nicolai the landscape is not good, Pharo really lacks mature libraries . Sure we like to bash Java but Java libs are rock solid and very well documented. I bring Java as example. Again I am not complaining at all, I knew when I came to Pharo that I will have to face these limitations. I also don't feel comfortable asking questions all the time as if I want others to do my code but I did not have much of a choice. I just cant deal with the lack of documentation any more. I think Pharo as a general idea is great , you definitely have taken the Squeak fork one big step further but you have a very long road ahead of you to make Pharo a modern environment. Asking for animating a window with good performance is one of the very basics of a good GUI API. I know you have limited resources and once again I am not complaining at all I just present my opinion. Its clear that Pharo needs a lot more people to contribute and bring the system forward at least to solve the basic problems. Thank you all people who helped me. But I don't think it worths to make my project in Pharo, too many problems. I feel privileged to have helped you with my contributions , I wish the Pharo the best. I could return back to Python but I think its time for me to bite the bullet and learn C/C++, since graphics is an area that deeply interest me (more as an artist less as a coder), so I don't have much of choice. Maybe I can brings some of my code back to Pharo with NB wrappers , I definitely will keep a close eye on Pharo. In a few months I will also present to the Pharo community a secret last contribution ;) On Sun, Sep 14, 2014 at 6:26 PM, phil(a)highoctane.be <phil(a)highoctane.be> wrote: > Do you know anything better for futuristic UIs at the moment? > > I guess that we aren't talking about commercial dev here.

Do you know anything better for futuristic UIs at the moment? I guess that we aren't talking about commercial dev here. And if we would rely on everything being documented in Pharo, errr, we wouldn't go too far. That being said, there are plenty of examples in the Woden code.

Why should he use it, now? I mean, is there a stable API? Or a roadmap ? Sometimes it is a bit dangerous to trust on "bleeding edge" pharo frameworks. I did some work based on Roassal3D just to found out there won't be any further development. The same happens with Roassal and GraphET. The same can happen with Woden too :) 2014-09-14 14:13 GMT+02:00 phil(a)highoctane.be <phil(a)highoctane.be>: > Why not use Woden? > > Phil > Le 14 sept. 2014 12:51, "kilon alios" <kilon.alios(a)gmail.com> a Ã©crit : > > yeah I am afraid transparency is very important to me >> >> On Sun, Sep 14, 2014 at 1:34 PM, Nicolai Hess <nicolaihess(a)web.de> wrote: >> >>> 2014-09-14 11:32 GMT+02:00 stepharo <stepharo(a)free.fr>: >>> >>>> I remember that there was an animated gif support. >>>> Now I do not remember exactly. >>>> >>> >>> At least in squeak there is an AnimatedImageMorph, that can load and >>> display animated gifs. >>> That works and is quite fast even for multiple instances.

Re: [Pharo-dev] The Dilemma: Building a Futuristic GUI for Ephestos

by kilon alios

what ? where ? how ? ;) I can use anything that is documented and keep its windows inside pharo window. Looks like I will be sticking with plain morphic for now I have not seen any substantial benefit in all other graphic libraries. I have to investigate NBOpenGL but it feels like an overkill for me and last time I tried it I had all sort of problems with it and my graphic card. Have no issue using Woden but if its not documented at all, I will need examples that actually show me how to do this. But I feel the problem I am facing performance wise is at the core of Pharo, its just that pharo is not able to handle big animations. But I will keep investigating my options. I could go for more static GUI its not such a big issue and keep animations to a minimum.

I decided to add a comprehensive set of encodings, based on http://encoding.spec.whatwg.org/#legacy-single-byte-encodings (a list which more or less corresponds to the encodings list supported by popular browsers). The mappings themselves are still taken from http://unicode.org/Public/MAPPINGS So now Pharo (Zinc-Character-Encoding-Core) supports the following byte encodings: ISO/IEC 8859 1, 2, 3, 4, 5, 6, 7, 8, 10, 13, 14, 15 and 16, Windows Codepages 866, 874, 1250, 1251, 1252, 1253, 1253, 1254, 1255, 1256, 1257, 1258, KOI8 R & U as well as Mac Roman & Cyrillic - each of these with a number of aliases like latin1, latin2, latin3, latin4, latin5, latin6, cyrillic, arabic, greek and hebrew. Furthermore, identifier mapping has been made more liberal (case and separator insensitive). For now, this is in Zinc #bleedingEdge > New byte encoders are easy to add, based on the official Unicode mappings that can be found here: http://unicode.org/Public/MAPPINGS (these are automagically parsed). > > Please help us make Pharo more international friendly. > > Sven > >
