[Pharo-project] 2.0 compiler bug

by Camillo Bruni

We still have a very nasty compiler bug open for 2.0 https://code.google.com/p/pharo/issues/detail?id=6601 The bug currently blocks all loading of configurations, since all references to previously undefined classes are not properly resolved => Compiler recompileAll is currently the only solution. Does anybody know where the undefined globals are handled? Otherwise I'll dig into it tomorrow morning...

Re: [Pharo-project] A small quiz: longest selector

by H. Hirzel

This means that a browser which is just like a regular natural language dictionary could be useful. A list of buttons (or a list) with A...Z and then just the list of selectors and their class and comment. Not actually new thing. I think Ernest Micklei from the Netherlands had a web site displaying Smalltalk methods this way it seems no longer accessible. Such a list in the browser would be much handier. --Hannes Another note: The discussion about Symbols reminds me that we actually have 'Atoms' in Smalltalk. More on this see http://live.exept.de/doc/online/english/programming/stForLispers.html "Like Lisp, Smalltalk provides atomic character strings, called "symbols". In Smalltalk, these behave much like strings, with the exception of being read-only (i.e. their character elements cannot be changed) and being unique (i.e. they can be compared using the identity compare operator #'==', as opposed to strings, which should be compared using the equality operator #'='). The Smalltalk message "asSymbol" corresponds to the Scheme "string->symbol" function. " On 9/13/12, Sean P.
