How to view hierarchy of multiple classes in a package?

by Tim Mackinnon

Hi guys - I'm trying to get back into pharo, and check out the advances in v5. Anyway, if I look at a package in the system browser, it shows me classes in that package (i think my terminology is right here?). What confuses me, is his I can see the hire hybrid the classes in relation to each other? The hier button just shows the hierarchy of the selected class and not in relation to the others? I'm sure at some point pharo and squeak let you see the related hierarchies of all the classes in the package didn't it? This is really useful to help understand the relationship between classes and pure risky identify useful refactorings. I can't see how to do this in pharo anymore? Is this functionality that has been lost (which seems a shame)? Or am I missing another useful browsers? Tim Sent from my iPhone

Re: [Pharo-users] Japanese Fonts

by Evan Donahue

Hi, thanks for the reply. FreeType disable/reenable seems to have done the trick. It loaded up my system fonts, and I was able to select Noto Sans CJK JP, which seems to do the trick. For reference, this is on Pharo 6 #60334. I also installed this for text entry: http://smalltalkhub.com/#!/~tomooda/Tekka and it seems to work like a charm.

Re: [Pharo-users] Launching OSWindow windows when in headless mode

by kmo

By the way your command line : ./pharo -headless Pharo6.image eval --no-quit "OSWindowWorldMorph new open" works fine. So it must be something to do with how my window is opened. I have a method that is called from the eval command line |a| a:= AppMorph new. a extent:1000@580. a color: (Color r: 0.13 g: 0.13 b: 0.13 alpha: 1.0). a sticky: true. a openInExternalWindow. a owner osWindow title: 'My App'. perhaps the problem lies here.

Re: [Pharo-users] Launching OSWindow windows when in headless mode

by kmo

It's strange - if I run: ./pharo -headless Pharo6App.image eval "MyApp run" then I get the error: /libSDL2-2.0.so.0: cannot open shared object file: No such file or directory/ But the main pharo window opens up followed by my OS WIndow. So that works fine despite the seeming error, But if I run ./pharo *-headless* Pharo6App.image eval "MyApp run" then I get the same error but no window opens up at all. -- View this message in context: http://forum.world.st/Launching-OSWindow-windows-when-in-headless-mode-tp49… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Launching OSWindow windows when in headless mode

by Denis Kudriashov

Hi. I played with such idea few month ago. And it was worked. I use this script on Mac: ./pharo Pharo6... eval --no-quit "Author useAuthor: 'test' during: [ OSWindowWorldMorph new open]" where "pharo" was script for headless run. Maybe Author do not need anymore. There was issue around it. I think your error (libSDL2 not found error) not depends on headless mode. And it would be same if you open external window from normal pharo UI.

Launching OSWindow windows when in headless mode

by kmo

I would like to launch my application main morph in an OS Window from a pharo image run in headless mode from the command line. But this just gives me a libSDL2 not found error. I'm using pharo 6 on linux. Is it possible to use OSWindow to open windows from a headless image? I want my main application window to be an OS window rather than the pharo application window. The big advantage of doing this (on linux at least) is that you have control over the title and size of the window. It is not possible to set the size and title of the pharo application image window in linux because of bugs. I thought launching my app in an OS Window might be a good workaround but it doesn't seem to work. -- View this message in context: http://forum.world.st/Launching-OSWindow-windows-when-in-headless-mode-tp49… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Japanese Fonts

by tesonep＠gmail.com

Hi, which version of Pharo are you using? Where do you install your font in your linux system? This is because Pharo is looking for the fonts in the paths '/usr/share/fonts' '/usr/local/share/fonts' and ~/.fonts. So maybe it is not finding them. This is not the ideal solution, because if you have another font directory configured you can't use it (even though, adding your custom directory is as easy as modifying a method :) ). Have you tried to disable and reenable FreeType support in the settings browser. It will help as when freetype is enabled the font cache is reconstructed. Also you can try to set the font from that settings browser. If it is shown in the font dialog when using the system browser you can use the font. Cheers, Pablo.

Japanese Fonts

by Evan Donahue

Hello, I am trying to get Japanese characters to show up in my Pharo image. Following some advice I found on google, I have set my font to something that I think should handle Japanese characters: defaultFont := LogicalFont familyName: 'Droid Sans Fallback' pointSize: 18. StandardFonts defaultFont: defaultFont. I then used the settings browser to force that to all system fonts. I did not notice a change to any of the text when I did this, so I am not sure it worked. Also, Japanese text still shows up as spaces. Does anyone know whether this is something I need to deal with in Pharo, on Ubuntu, or both? As far as I can tell, the font is on my system. Thanks, Evan
