Hi Bernd,
YES and NO in ObjC are translated to true and false in MacRuby.
so you were probably after:
NSNumber.numberWithBool(false)
(I am curious as to how often that is useful actually)
I will leave the table idea for others to comment - I actually think
in the end there are only a few rules to learn and then you will
find yourself translating easily (not that those rules should not go
in a cheat sheet somewhere - that's probably a good idea).
Shure, there are only few rules, but:
1. there are newbies outside (most of the Obj-C programmers)
2. why should I manually correct those Obj-C things like [aObj: foo] a
thousand times when it can easily be done by a regexp? I don't want a
real translator, I am wanting just a simple []-remover!
With:
NSDictionary.dictionaryWithObjectsAndKeys "a", "b", nil
I assume that in the original ObjC method is actually passing an
array which (it seems) must be terminated by a nil (in objC).
I actually ran across this in another context - passing objects in
this way - again I will leave others to comment on it, perhaps it is
an issue.
However why can't you use :
dict = {"b"=>"a"}
=> {"b"=>"a"}
#check class of created dictionary
dict.class
=> NSMutableDictionary
Why use the long winded ObjC form?
Perhaps you misunderstood me. I know this already and I don't want to
use the long form, I just typed that in macirb to use the RESULT (in
this case {"b"=>"a"}). Perhaps this is the way a Obj-C programmer is
trying out MacRuby because of lacking of documentation.
Bernd
