fixed. Alex this chapter alone is really nice to present OOP and OOD and Pharo to people can start. I'm adding some points to answer question raised by my son and it will be ready to rest. Stef

Yes you are right I will move syntax in an appendix. And I should probably see what is the essential and have a basic intro to syntax. > That are the only parts I read, up to now ... I'm measuring how time it takes me and this is slow :( I hope to get faster but I'm just slow. Took me two week evenings for expressions but it is really a nice overview of OOP. I'm revising it based on questions of my son.

Looks very promising. It is a great, much needed subject area. And a huge task as well. I personally like chapter 7 as introduction, a lot, in terms of conceptual approach. If it were me, I would put it first (but the current intro reflects that already a bit, so I am not sure). Also, personally I like to introduce syntax in a less complex/intimidating way, skipping some of the weird/special parts, those could go in a later 'advanced syntax' part, to stress how simple the basic/most used syntax actually is. That are the only parts I read, up to now ... > On 8 Jan 2017, at 17:24, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: > > I released a version of a little expression interpreter for the new book: Object-oriented programming and design with Pharo. > > https://ci.inria.fr/pharo-contribution/view/Books/job/LearningObjectOriente… > > Typos are welcome as pull requests. > > Stef

Re: [Pharo-users] Pharo and WebAssembly

by stepharong

Richard Start to think about your vocabulary. If you give me 0.00001 % of the money put in Java or JS we will do a lot more. Now we do what is important for the community with the ressources we get. And again take one little topics: - writing a tutorial - coding an app - writing a wrapper for an hypercool trendy library - have fun with moose or roassal and DoIt but for yourself and the community.

Hi Stef! You have written a lot of material. This is great! I had a look at the chapter about the interpreter. Looks great!

Re: [Pharo-users] Amazing Grace

by Offray Vladimir Luna CÃ¡rdenas

Yes, a more correct statement would be a man alone can spark a lot of things, but renaissance is a collective endeavor. In all of he examples you mention, small teams work in tandem with more broader cultural phenomena, like acceptance of a movie or programming language. My point was this organic connection between individual advertising and more collective, grassroots efforts (even if communities are small).

Re: [Pharo-users] Mongo voyage connect to database with authentication fails

by Sabine Manaa

For unknown reasons my mail did not go through the mailing list - perhaps this answer does ist. after switching the authentification mechanism to MONGODB-CR instead of SCRAM-SHA-1, it works. So, I assume, Mongo voyage does not support SCRAM-SHA-1. Will there be a support in future, anyone knows? -- View this message in context: http://forum.world.st/Mongo-voyage-connect-to-database-with-authentication-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

For example I want to add matcher/rewrite tool as tab which will work on selected scope. So in system browser it will allow search/rewrite in selected package, selected class, selected group. And same tool will be very useful in message browser too: ability to search/rewrite over results of method query (senders/implementors). I have in mind a couple of other extensions for both browser types. And I hope people will contribute in this direction when I document how extend Calypso
