Re: [Pharo-dev] I love the Pharo 3 Dark Theme

by Esteban Lorenzano

thanks for the nice comments. yes, Iâm working on making it something better that a hack (I will probably finish it next week). Then, we think on including it in a future update on Pharo 3. nowâ¦ it will be available, but I do not think it will be the default theme. But it will be there for choosing it. Also, I think theme it-self still need some care, let me know your findings and I will fix it as soon as possible :) for programatically, I have added a fonts.st fonts to the autoconfiguration of pharo StartupLoader default executeAtomicItems: { StartupAction name: 'Fonts 3.0' code: [ | pointSize fontName codeFontName | FreeTypeSystemSettings loadFt2Library: true. FreeTypeFontProvider current updateFromSystem. pointSize := 10. fontName := 'Source Sans Pro'. codeFontName := 'Source Code Pro'. StandardFonts setAllStandardFontsTo: (LogicalFont familyName: fontName pointSize: pointSize); haloFont: (LogicalFont familyName: fontName pointSize: pointSize - 1); balloonFont: (LogicalFont familyName: fontName pointSize: pointSize - 1); windowTitleFont: (LogicalFont familyName: fontName pointSize: pointSize + 1); listFont: (LogicalFont familyName: fontName pointSize: pointSize); menuFont: (LogicalFont familyName: fontName pointSize: pointSize); codeFont: (LogicalFont familyName: codeFontName pointSize: pointSize) ] runOnce: true. }. this is usually in: OSX: ~/Library/Preferences/pharo/3.0 Linux: ~/.config/pharo/3.0 (Iâm not sure, but somewhere there) Windows: no idea :) cheers, Esteban On 14 May 2014, at 14:48, Goubier Thierry <thierry.goubier(a)cea.fr> wrote: > > > Le 14/05/2014 14:36, Esteban A.

Re: [Pharo-dev] Smalltalk Virtual Machine, StVM

Yeah you are right Goran. The way I write it is incorrect. My bad. It embeds the python runtime it does not reimplement it. 2014-05-14 14:00 GMT+02:00 phil(a)highoctane.be <phil(a)highoctane.be>: > On Wed, May 14, 2014 at 1:52 PM, ClÃ©ment Bera <bera.clement(a)gmail.com>wrote: > >> >> 2014-05-14 12:27 GMT+02:00 askoh <askoh(a)askoh.com>: >> >>> There is a trend of making languages to run on Java Virtual Machine.

They always exist and do not move in memory. They cannot become obsolete whatever you do. Now you can also create classes at runtime in java (I think with something called java.lang.Class). In this case, it is a regular object in the heap, and the class may be garbage collected. There are specific API to add methods to those classes and I don't know how it works. It may be that you have a literal array per method but I don't know. Obsolete classes are created by the Pharo IDE when we manually delete a class. I'm not sure you can do that in java, and if so, the obsolete problem depends on the implementation of the dynamic class library you are using (as java.lang.Class). > >> Another detail is that not all smalltalk can bootstrap from sources (for >> example it is the same heap that we have used and edited in Pharo for the >> last 3 decades, the unique instance of True may even have been instantiated >> by Dan Ingalls in 1980 and we are still using it). >> >> So basically it is either you have smalltalk running on the jvm wihtout >> the live smalltalk abilities, or you have a full smalltalk but it is slow. >> >>> >>> How about running Java on the StVM so that Java can have the live >>> environment and debugging capabilities like in full blown Smalltalk?

Ehm, no... its a plugin that includes the CPython runtime. So it embeds Python. And then has lots of nice stuff to talk between. regards, GÃ¶ran

Re: [Pharo-dev] geometric framework

by Alexandre Bergel

Roassal does not support geometry. It would be great to have one however. Using Roassal you will need to do everything by hand and implementing all the sweet formulas. DrGeo is probably the way to go for now Alexandre > On 14 May 2014, at 08:05, Natalia Tymchuk <natalia.tymchuk(a)unikernel.net> wrote: > > Hello. > I want to do visualization on Roassal and I need the geometric shapes and their properties, for example: > build circle on 3 points; > find mid perpendicular. > > Can you tell me does some framework exist or no? > Thank you. > Best regards, > Natalia.
