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

by Sven Van Caekenberghe

Jimmy, Use the right font, for example Ariel Unicode MS, and you'll be able to display strings in those languages just fine. Processing these strings also works just fine. Now, editing them right-to-left is not possible.

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

by Jimmie Houchin

For myself and my goals. Yes, I only want to display RTL language and in its one container. I do not know if that is the appropriate GUI terminology. I am wanting to do some textual comparison of Hebrew, Greek and English texts. Other languages later. They will each need to be synced with each other by either row by row (line by line) or with text in columns. Each language in its own row or column depending on the desired view. I will want to edit each language appropriately in its container. IDE or workspace/playground support is not required at this time. Is it reasonably achieve this in a Pharo app using the latest Pharo GUI, GT, Spec, Bloc, Brick, ...? If so, then I will start learning and get going. If not I will look elsewhere for accomplishing this project. But Pharo is my first choice. I would love to not have to move to Qt or JavaFX or some such. Thanks.

Nope but you could use something like OSProcess to open those videos in VLC from inside pharo On Mon, Jan 11, 2016 at 4:53 PM H.

Hi Jimmy, AFAIK thereâs no IDE support for RTL languages. You only want to be able to display the strings correctly though, right? Iâm pretty sure that itâs already possible to load the font. The problem is probably with the editors and workspaces. They would need to be told to display the string differently.
