Refactorings - Push down several instVars

by phil＠highoctane.be

It is only possible to do this one variable at a time... How to do a set of vars all at once? Same story for quite a couple of refactorings... Thanks in advance! Phil

about ~=

by Christophe Demarey

Hi, I would like to make a suggestion that may lead to a long debate but let's go: What do you think about deprecating ~= and replace it with != for example? Why? In mathematics the symbol ~ is used for equivalence. To me (and I think any newcomer to Smalltalk) the first guess of the meaning of ~= is equivalent to => missed. The meaning is totally different: "Answer whether the receiver and the argument do not represent the same object." I never used this method because it is too confusing for me. I prefer to use (a = b) not or (a = b) ifFalse:. So, the discussion is open ... Christophe

Pharo and Amber relationship

by Torsten Bergmann

Hi, as I read somewhere that Amber want to stay compatible with Pharo (at least with the core classes) I wonder how this compatibility is measured/enforced these days. Are there tools to exchange code between the two? I also wonder if what would be necessary to run Amber on Java Nashorn (a JS engine that comes with the JDK 8). Could serve as a horse to also run on JVM... Why I'm asking: I think one of our goals should be to make Pharo more widely usable to not end up as an island. If Pharo and Amber stay compatible to a certain amount Amber could open the door for Pharo to other target platforms (browser, mobile devices, other language runtimes) as JS is available nearly everywhere. Thx T.
