RVM + Xcode 4
by Rafael Felix 09 Dec '11

09 Dec '11

I've installed MacRuby using RVM, but in the xcode 4 the MacRuby Framework has been marked as red, and I'm felling something is wrong. There's more setup to do? my best regards -- Rafael Guzi Felix da Silva MSN: rafaelguzi(a)hotmail.com Blog: http://blog.rollingwithcode.com / http://rollingwithcode.heroku.com Twitter: @rs_felix Github: http://github.com/fellix Curriculum: http://zerp.ly/felix_rafael

Single Column Table View with Core Data backed Custom Cell View?
by Haris Amin 08 Dec '11

08 Dec '11

Hey Guys, I have a Core Data entity called Email all set and ready to go. Following Matt's example from the book, I was able to create a regular old NSTableView and bound the Core Data Email entity's values to each column in the tableview. This works great. What I'm now trying to do is make a single column tableview where each row will display a custom cell view constructed from my Core Data Email object. With me so far? :) Basically, if you look at the Mail app from OS X Lion, I'm trying to create that side bar single column tableview where each email message has a custom table cellview showing the from, to, subject, and summary for each Core Data email values. With a regular old tableview this is easy, I'm just a little lost as to how to get a single column table view to render a custom cell view that uses Core Data binding to match my Email NSArray Controller. This is a symbolic representation of what i'm trying to achieve: NSTableView ( 1 column) > NSColumn (bound to my CoreData Email entity) > NSTableCellView ( I want this to show the actual text fields for the bound coredata object for that row i.e. email.to, email.from, email.subject, etc.) A little lost and any help would be much appreciated. Thanks :) Haris

Thx Terry, that might be an idea .. the calculations are not that diff so i could rewrite them in Obj-C to keep the task object small … or the other way around: i'll create a task with a panel and pipe the cancel to the process Rob Could you wrap the process into an NSTask and use pipes to communicate?

ruby structure for NSOutlineView
by François Boone 07 Dec '11

07 Dec '11

Hi, In the same way that this tutorial (http://developer.apple.com/library/mac/#featuredarticles/UsingMacRuby/_inde…) I try to implement a NSOutlineView controller in ruby to make a simple tree in the left part of a window. I read the documentation of NSOutlineView, tasks and I understand I have to write at least four methods in my controller class: • – outlineView:child:ofItem: • – outlineView:isItemExpandable: • – outlineView:numberOfChildrenOfItem: • – outlineView:objectValueForTableColumn:byItem: My questions are: 1) what kind of object I have to use in ruby to fit with outlineView structure? If I understand I need a structure like: Parent_1 : child 1, child 2 Parent_2 : no child Parent_3 : child 1, child 2, child 3 2) Is a Hash like this: Hash[ "Parent_1" => ["child 1", child 2"], "Parent_2", Parent_3 => ["child 1", "child 2", "child_3"]] can be the solution? 3) where I can find this kind of information: the mapping between ruby data structure and NSObject data structure (for future use)? 4) and the last one: I think I do not understand what is item in the last method: – outlineView:objectValueForTableColumn:byItem: item: An item in the data source in the specified tableColumn of the view. So, if I want to make a simple tree, I should have just one column, and then item should be Parent_x or child_x: Is it right? Thank you for reply François

Jonathan Penn put together a website to show your love for MacRuby and desire to have it run on iOS: http://welovemacruby.com/ While I don't think we can really pressure Apple in doing anything, I think it's nice to show your love. - Matt

Face detection sample
by Matt Aimonetti 01 Dec '11

01 Dec '11

The other day @seanlilmateus wrote a quick face detection script using MacRuby: https://gist.github.com/1386468 I cleaned up his script and made it more Ruby-like: https://gist.github.com/1417463 as well as added support to pass your own image. You can try the script your self easily: $ macruby -e "$(curl -fsSL https://raw.github.com/gist/1417463/8cd0150bf5de962468897b3da093c870a5fb53d…) ;" While the script is far from perfect, I was thinking that it would be interesting to see the "MacRubyficiation" of a code written by someone who probably knows Objective-C/Cocoa but is new to Ruby. - Matt
