Re: [Pharo-dev] Right to Left languages and fonts

by Dimitris Chloupis

Moprhic is the official GUI API of Pharo , many morphic elements come with a font: message that allow you to use custom fonts, I use robotic looking fonts for my ChronosManager, with custom size that is not affected by pharo settings. So yes Morphic is very flexible.

Re: [Pharo-dev] Pharo50 spur works on CentOS?

by Blondeau Vincent

Thanks for your answer. However, it seems that the server does not start with: ./pharo -vm-display-null -vm-sound-null Pharo.image --no-quit eval "ZnServer startOn: 8080." Nothing in the terminal and no open port in "netstat -an" While, this command is writing something in the terminal: ./pharo -vm-display-null -vm-sound-null Pharo.image eval "ZnServer startOn: 8080." a ZnManagingMultiThreadedServer(running 8080) Vincent > -----Message d'origine----- > De : Pharo-dev [mailto:pharo-dev-bounces@lists.pharo.org] De la part de > Sven Van Caekenberghe > EnvoyÃ© : lundi 11 janvier 2016 17:03 > Ã : Pharo Development List > Objet : Re: [Pharo-dev] Pharo50 spur works on CentOS? > > > > On 11 Jan 2016, at 16:51, Blondeau Vincent > <vincent.blondeau(a)worldline.com> wrote: > > > > Hello, > > > > I just wanted to run a latest Pharo image on a CentOS server to run a Zinc > server. > > So I did: > > curl get.pharo.org/50+vm | bash > > > > ./pharo Pharo.image eval â1+1â evals to 2 > > > > But, > > ./pharo Pharo.image --no-quit eval "ZnServer startOn: 8080." > > returns: > > ioLoadModule(/root/Pharo/pharo-vm/libFT2Plugin.so): > > libfreetype.so.6: cannot open shared object file: No such file or directory > > > > So the server is not launchedâ¦ > > > > What are the libs that should be installed on the machine?

Re: [Pharo-dev] Right to Left languages and fonts

by Jimmie Houchin

Okay. Thanks for the help. I do not have that particular font. I am on Ubuntu. But it appears that the standard Arial does have a version of Hebrew glyphs. It took me a couple of tries to get it to work. I had to close the Playground I had open as it remained in the original font. But when I inspected the string. The inspector displayed the correct fonts. After I changed fonts and opened a new Playground. The new Playground displayed Hebrew and Greek correctly. I would presume when I develop the user interface I can select whichever Hebrew or Greek font I want to display in that UI element? It does render them in reverse order. But I would think that I can take care of that in my GUI display element. It is challenging to display RTL and LTR languages together. When I do so in LibreOffice it is a strange experience as to which direction the cursor is operating. :) Again thanks. I am encouraged to proceed. :) Jimmie Houchin On 01/11/2016 09:32 AM, Sven Van Caekenberghe wrote: > Jimmy, > > Use the right font, for example Ariel Unicode MS, and you'll be able > to display strings in those languages just fine.
