Re: [Pharo-dev] [Pharo-users] Phratch one-click

by Hilaire Fernandes

Hi Jannik, Don't use the change/update event mecanism. This mean a lot of changes in your model. In DrGeo I use a simple loop to update the sketch, but i guess it is more complicated with Pratch as you have parallel threads. In the other hand, is the original Scratch implemented with change/update? If so why it is not as slow?

Re: [Pharo-dev] [ANN] RenoirSt 1.0.0 Release for Pharo 3.0

by Torsten Bergmann

Hi Gabriel, Â nice work - now designers should start learning Smalltalk to be able to refactor large style definitions :) Â Some feedback: ============= the new "RenoirSt" project unfortunately conflicts with the "Unit" package when both get loaded from the config browser in Pharo 3.0: Â - RenoirSt loaded: Â "2 px" returns an instance of CssLength (px is an extension method on Integer) Â - Units loaded: Â Â "2 px" returns an instance of UnitValue (px is an extension method on Number) as you have defined own custom "units" in category "RenoirSt-Units". Â I would really like to see that RenoirSt is reusing the common Units package instead of reinventing/conflicting as the Unit package already provides pixels, millimeters, ... support including conversion. Reuse is keyÂ and would avoid duplicated effort.Â Â For instance Artefact, the PDF framework is using Units as a prerequisite already too - as it alsoÂ has to deal with mm, pixels, points, ...Â Â Should be no problem to add missing CSS lengths like #em to Units project as well. Just ask Marcus Denker to add you as a contributor to http://smalltalkhub.com/#!/~MarcusDenker/Units/ Then add Units as a prerequisite similar to ConfigurationOfArtefact and use it in your code.Â Â Â Regarding features: =================== For Seaside there is a project called "Seafox" generating Seaside #renderContentOn: methods from HTML. http://lists.squeakfoundation.org/pipermail/seaside/2010-August/023993.html Maybe you want to build something similar for #cssContentOn: to support a better roundtrip with designers. Bye T. Â Gesendet:Â Dienstag, 11. MÃ¤rz 2014 um 14:13 Uhr Von:Â "Gabriel Cotelli" <g.cotelli(a)gmail.com> An:Â "Pharo Development List" <pharo-dev(a)lists.pharo.org> Betreff:Â [Pharo-dev] [ANN] RenoirSt 1.0.0 Release for Pharo 3.0 Hi, Â I'm announcing the first official release of RenoirSt, a DSL enabling programmatic cascading style sheet generation for Pharo. Â For the impatient, you can load it in your 3.0 image evaluating: Â Gofer it Â Â Â Â url: 'http://smalltalkhub.com/mc/gcotelli/RenoirSt/main'; Â Â configurationOf: 'RenoirSt'; Â Â loadStableÂ Â or download a ready to use image from the Contribution CI Server[https://ci.inria.fr/pharo-contribution/job/RenoirSt/]Â ( a ConfigurationBrowser option comming soon).
