Hi, when reloading FreeType (Settings > Use free type:) and then trying to change the font (Standard Fonts >> default) some inputs are not drawn and the UI freezes completely. Interestingly if I press alt+<dot> the UI doesn't respond, but the Image clearly does because there is output in the command line: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ âUser Interrupt [ delaySemaphore wait ] in Delay>>wait in Block: [ delaySemaphore wait ] BlockClosure>>ifCurtailed: Delay>>wait BlMainLoopManager>>interCyclePause: BlMainLoopManager>>doOneCycle [ self doOneCycle.

thanks for looking at it. Bloc needs feedback Le 5/7/15 12:16, Peter Uhnák a écrit :

Hello, Thanks for experimenting Bloc!!!. I think that, In this case, this is the font chooser that freezes, not Bloc. You can always come back to Morphic with CMD+Backspace. Then remove the freeze block space, create a new bloc space and switch to it. I guess it is because current standard fonts are strike fonts. Try by selecting source code fonts first, as a consequence default fonts are set to FT fonts. Then open the font chooser. it should be ok. Because of Athens and of TxText, no effort was made to make strike font usable with Bloc. Now, I donât know exactly why the font choose behaves like that. Cheers Alain

Hi,
when reloading FreeType (Settings > Use free type:)
This is an Athens issues. Athens only "officially" supports vector fonts. Drawing with bitmap fonts is a hack (and that happens during disable/enable freetype). fixed in athens repository: Name: Athens-Cairo-NicolaiHess.89 Author: NicolaiHess Time: 5 July 2015, 5:31:21.319671 pm UUID: f2a202d8-67fb-984c-a75a-21820d8fa9d4 Ancestors: Athens-Cairo-Nicolaihess.88 convert text string to utf8 converted buffer for cairos cairo_show_text method

@peter Did you try it, does it work for you ?
Sorry it felt under radar... yes, this does work! however I managed to encounter two more bugs along the way Pharo space: everything is underlined/bold as expected Bloc space: no styling (this is same behavior both before and after loading Free Type) ââ And second thing (that may not be so obvious from the screenshot) is jaggedness of the font in Bloc (that's why I was messing with fonts in the first place). I suspected that Font Hinting (Settings > Appearance > Use Free Type ... > Advanced Features > Hinting) was incorrectly configured, however when I tried to change it it had no effect. So my conclusion that fonts are not yet fully implemented or something else is missing? Or is my system/configuration wrong? (The image is Bloc build #609 from pharo-contribution). I actually have the very same problem in text rendered in Roassal (Athens canvas), so I blame Athens. Is there a solution for this?

however I managed to encounter two more bugs along the way
Pharo space: everything is underlined/bold as expected
Yes, I know this one. It is because there are different ways how textemphasis is handled. In a text teditor for example, we use the full Text object. And in a list view it is only the first character/text that defines the emphasis for the whole text line. I ported only the first one yet for athens.
Bloc space: no styling (this is same behavior both before and after loading Free Type)
ââ
And second thing (that may not be so obvious from the screenshot) is jaggedness of the font in Bloc (that's why I was messing with fonts in the first place).
Yes, small fonts look ugly with athens/cairo font rendering. This looks a little bit better if we enable/change the subpixel filter for FT and cairo (there is a bug report at fogbugz, but I don't know if we will do this ever or if it is possible at all.
I suspected that Font Hinting (Settings > Appearance > Use Free Type ... > Advanced Features > Hinting) was incorrectly configured, however when I tried to change it it had no effect.
This settings only control the options for the FreeTypePlugin used in Morphic. Athens/Cairo uses a different way for rending (cairo uses freetype too, but the "normal" pharo freetypeplugin and cairo are using freetype differently ). But you can control Cairos font options too (Look at class CairoFontOptions).
So my conclusion that fonts are not yet fully implemented or something else is missing? Or is my system/configuration wrong? (The image is Bloc build #609 from pharo-contribution). I actually have the very same problem in text rendered in Roassal (Athens canvas), so I blame Athens. Is there a solution for this?
Yes, this is all about athens resp. athens cairo backend.
Thanks, Peter
