Re: [Pharo-dev] Big claps for Epicea (small request!)

by Nicolas Cellier

format before diff is in the top 5 of my most hated default. As an author, I try to write short methods and adhere to a standard format (Kent Beck like). But I want the freedom to use derogation when the format helps comprehension. If I did the effort of using a special formatting, the last thing that I want is a "smart" tool that undo my work. The best time to format code is when we accept it, and only if there is a quick way to undo/bypass if we don't like it. The formatter is dumb. Let's illustrate it with literals among other things. I might want to write 16rBADA55, but I'm sure i never want to read 12245589, it makes no sense ;) (hey, this is a real example you can find in VMMaker sources, not just the production of my ill brain). And if I make an effort to format a character encoding table on several lines to have it readable #( line1 line2 ... lineN ). I'm pretty sure I never want to diff a single line with about 1024 columns... So please make this an option (with a default to false)! 2017-07-19 22:27 GMT+02:00 Mariano Martinez Peck <marianopeck(a)gmail.com>: > Hi Martin, > > Thank you VERY MUCH for Epicea.

Big claps for Epicea (small request!)

by Mariano Martinez Peck

Hi Martin, Thank you VERY MUCH for Epicea. I just had a crash and it was way more comfortable to recover changes. One small request would be to allow "Pretty Print" in the diff to the changes to be applied. Many times I changed formatting etc so for when viewing changes, viewing with same formatting helps me to see the actual changes and not formatting changes. Thanks! -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-dev] [Ann] Keccak hashing algorithm

by Stephane Ducasse

Thanks Norbert. The consortium paid nicolas to deliver iceberg and esteban to push further for git because the world is moving and git and github support will give us a lot of exposure and a really powerful distributing versionning source control system (even if I really enjoyed MC - it is showing its age - I will be also happy when Smalltalkhub will be a nice legacy not getting in my way. For the record people close to me know that I do not like git even if I like its underlying social model - fork and we pushed git not by accident. But to sustain business and our community. I often have the impression that we are ants fighting together while elephants (python, ruby, JS) are running around. I spent a lot of time pushing Squeak in the past - I'm basically the guy that wrote most books and produced a lot of teaching material on Squeak, but I arrived to a point where I decided that there were no reasonance about the vision (innovation and business) I wanted for a new generation smalltalk so I decided that Squeak was ok for me and that all my energy is for Pharo. I do not like to compete to runner competition with snowshoes while others have supercool nike and this "let us do something compatible" like forcing me to wear snow shoes. I paid attention to avoid non backward compatible changes but after a while what should be done should be done. I think that since 2008 we show that we value: community building, business support and delivering an excellent system. So I'm like you, if everything I do should be compatible with Squeak and others then I should better go and do fun stuff in Lua, Python, Ruby or JS. People may think that it is sad or that I'm arrogant asshole: I do not care because this is my fun and my life. Pharo is open and people are welcome to build it with us. We are always really open to co-build it but it also means taking responsibility. So thanks for sharing the vision with us.
