Hi, is there a trunk-commiter that would take care of including this? Background: In a class of mine i had a method with a special selector that contained a space (I needed that, really, and had it working) but then the senders/implementors button stopped working: instead of _______________ |some selector| +-------------+ |msg:with: | |value: | |at:put: | +-------------+ I got ___________ |some | +---------+ |selector | |msg:with:| |value: | |at:put: | +---------+ which, additionally, resulted in an off-by-one when clicking an item: clicking on 'value:' resulted in the list of senders/implementors of at:put: The Provided patch fixes this behaviour.

terse Object concatenation
by Chris Muller 26 Sep '10

26 Sep '10

I would like to integrate this elegant extension to the object-concatenation API. Just as Exceptions may be easily concatenated with the #, (comma) selector, now any object may, as well: object1, object2 --> "{ object1. object2 }" and, equally, with other collections: { object1. object2 }, object3 --> "{ object1. object2. object3 }" I find this particularly useful for user-interfaces that apply Smalltalk interpretation to user text input, that the user was able to write "lists" of items in a very terse and natural way rather than demanding curly-brace developer-syntax. I do not wish to reopen philosophical discussions; this is right in-line with the spirit of Squeak's other concatenation conveniences. There were no major objections when I proposed this a couple of months ago, and if that is still true, I would therefore like to go ahead and merge these 5 new methods into the trunk later this week. - Chris

The presentation was great! There were about 10 Squeak/Pharo-ers there, from hobbyists to a surprise XEROX-PARC celebrity :) We had a dialogue, nudged along by a slideshow, which I posted at http://seandenigris.com/blog/?p=541 Sean
