here's a good step I think it settled well. encoders are next. I haven't got any java left . Merry Christmas! Here's the profile.

accessing local/instance variables with metalinks
by Peter Uhnak Dec. 14, 2016

Dec. 14, 2016

Hi, what is the best way to access variables from within a metalink? for example I have a message send `surface clear` and I want to change it to `surface clear: trachelCanvas color`. I can use #instVarNamed: ``` MetaLink new metaObject: [ :object | (object instVarNamed: #surface) clear: (object instVarNamed: #trachelCanvas) color. ]; selector: #value:; arguments: #(object); control: #instead. ``` but the above isn't exactly nice, plus it wouldn't work with temporary variables. Thanks, Peter

Contributing code
by Evan Donahue Dec. 12, 2016

Dec. 12, 2016

Hello, I wanted to ask if there was a good resource I could use to learn how to find out about current bugs and submit patches/code/contributions to the core Pharo classes (or other major Pharo projects). I'd like to be able to fix the things I encounter, I've just never gotten around to learning how. Ideally, it would be great if something could show me how to find and fix some minor tweak of a comment or something like that, just so I know the process. This seems like the kind of thing that is either obvious, or has been addressed somewhere, but for whatever reason, I've never been able to find it. Thank you, Evan

A little prototype kernel in 9 methods :)
by stepharong Dec. 11, 2016

Dec. 11, 2016

Hi guys I'm thinking to package some of my language design knowledge in a kind of book. Probably to be used to give a lecture on OOP languages. I have class-based reflective kernel. This is several years that I was thinking about prototype kernels and I decided to relax and implement one for fun over the week-end. I will probably look at mixins, traits, talents, split objects in the future. Since I cannot compile the book on jenkins, I join the pdf. Stef PS: I will finish Pharo by example now and focus on Learning OOP with Pharo. -- Using Opera's mail client: http://www.opera.com/mail/

seaside javascript builders
by Siemen Baader Dec. 10, 2016

Dec. 10, 2016

Hi all, I'm confused about the limitations and intended use of Seaside's javascript builders. I can follow that we can do eg: "(html jQuery: 'div') remove" or "html javascript alert: 'hello'" within the "renderContentOn: html" methods, but how do I deal with logic and variables? How do I eg. install an event listener and provide a browser-side function that extracts data from the event and then passes it to the server via "html jQuery ajax"? Is this something to be done in pure JS returned from the #script method? Thanks for any enlightenment!

Fuel fuelAfterMaterialization - wrong order?
by Petr Fischer Dec. 10, 2016

Dec. 10, 2016

Hello, I have "Model" class, dictionary instance variable in it and in this dictionary, there is "Task" and "Meeting" classes (Meeting is subclass of Task). I have problem with fuelAfterMaterialization order, if I log debug line in fuelAfterMaterialization, I got this fuelAfterMaterialization call order: Task Task Task ... Task Model (!) - here? why? Model is root object Meeting Meeting Meeting and some other objects, collections etc. Problem is, when I need to do some things with Tasks and Meetings in fuelAfterMaterialization of Model (eg. rebuild caches), I am excepting, that all fuelAfterMaterialization calls is done before on all Tasks and Meetings - because they are stored in instance var dictionary of Model. Is it a bug? Thanks! Petr Fischer
