Note, TTFileDescription, which caused the issues discussed, seemed to have been removed from Pharo when I checked Friday.

Re: [Pharo-project] [Metacello] What packages to load from Metacello in PharoDev?

Thanks Dale. I understood. I will give it a try and try to put it in next PharoDev. I will ask you in case of more questions.

by Mariano Martinez Peck

Hi folks. I am not sure how does it work the license in the collaborative book. So far in the footer of the book I saw: "Licensed under Creative Commons BY-NC-SA" Now...what does it mean? That everybody is agree that whan he writes will be with that license? I wonder..suppose in one year we want to take such book an generate a real pdf/printed book, will be there some problem with that? I want to avoid such problems in the future. Thanks Mariano

[Pharo-project] Architectural dependencies

by Alexandre Bergel

Dear List, I worked on the Issue #2107 during the Pharo Sprint of today. This issue proposes a minimal infrastructure to control the dependencies of your package. I cleaned the code proposed by Andreas. I introduced the class PharoCorePackageDependenciesTests. It contains few tests. An example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= testFile self testPackage: 'Files' dependsOnlyOn: #( 'Kernel' 'Collections-Strings' 'Compression' 'ToolBuilder-Kernel' 'Tools' 'System-Object Storage' 'Graphics' 'Collections-Sequenceable' 'Collections-Abstract' 'Collections-Streams' 'Collections-Arrayed' 'Multilingual' 'Exceptions' 'System-Support' 'System-FileRegistry' 'Collections-Weak' 'Collections-Unordered' ) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= This is interesting to see that File refers to the Graphics package! I provide a method to automatically generate this kind of tests. It therefore goes green. You can also inspect what are the dependencies. By dependencies, I mean static class references. You can find the code in the inbox: SLICE-ArchitecturalTests-Alexandre_Bergel.2 Cheers, Alexandre

Re: [Pharo-project] Do TTFonts prevent image startup?

by Igor Stasenko

There are two ways how to work with TT Fonts. One way is to use TTFontDescription, which fully reads font into object memory, so you can walk with it anywhere and it will work. Another way is to use TTFileDescription. This one is tricky, because it only caching glyphs data, while reads missing glyphs from files on demand. So, i think that was the cause of problem.
