Hi, Over the past couple of weeks Alex worked on stabilizing a first beta01 version for Pharo 6.1: https://twitter.com/feenkcom/status/929031849879461889 This is available as a beta01 tag in the pharo61 branch here: https://github.com/pharo-graphics/Bloc/tree/beta01 The main readme was updated with instructions and links: https://github.com/pharo-graphics/Bloc An overview of the improvements: - improved animations support that also works for scaling https://twitter.com/feenkcom/status/927617393194610693 - improved debugging support for transformations https://twitter.com/feenkcom/status/926040946130612224 - support for programatic testing of bloc mouse events: https://twitter.com/feenkcom/status/925672206763511808 - updated MemoryGame tutorial: http://files.pharo.org/books-pdfs/booklet-Bloc/2017-11-09-memorygame.pdf https://github.com/pharo-graphics/Tutorials - extended examples that offer a 52% coverage - new Bloc world menu for easily accessing Bloc examples and reseting the Universe Cheers, The feenk team -- www.tudorgirba.com www.feenk.com "The coherence of a trip is given by the clearness of the goal."

One can choose to convert Float -> Fraction (because fraction is the more general format, in that it can represent more of the real numbers) or to convert Fraction->Float (because a Float is considered an approximation of a real number). But more important, I think, is that whichever choice is made, the *same* choice must be made in *all* operations that involve both Floats and Fractions. Regards, -Martin

Re: [Pharo-dev] Encoding method source code in Tonel

Hi Nico, I have a fix for both cases you provided. now, I need to refactor it because is ugly how I solve it :) right now this is super agnostic: the only thing we ensure is to count correctly the brackets to be sure we have a complete method. All the cases you mention it are possible ways where a brackets can appear without being part of a block constructionâ¦ of which I think we can delimit.
