Just wanted to check something. In the BNF grammar we provided for the `is_XXX' features in the STRING class. Did we incontiously accept white spaces before...
... I think I did these (at least the initial versions). My understanding of BNF says that whitespace has to be written explicitely, e.g. like this: SPACE or "...
... No, whitespace is not accepted. We decided that stripping whitespace and parsing numbers are completely orthogonal. One reason is that the definition of...
Hello, a moment ago I realized that ARRAY lacks features to insert and remove items! (SmallEiffel can add_first, add_last, and remove, but not insert in the ...
... Could you be more specific? Which GOBO class? Besides of that, do you really think a generic insert routine is that bad for ARRAY? OK, it's frquently done...
Hello, ... and remove ... insert in the ... Yes it can. See the feature add(element: like item; index: INTEGER) in class COLLECTION. As for item removal, just...
... You can use the flat-short version of a class to check what features it has. You get this form e.g. for ARRAY by calling "short array.e". Regards, Arno -- ...
... My fault! You are right. Actually I used the short form, but searched for "insert" and "append". "add" did not qualify for that: add (element: like item;...

... OK. ... IMHO, STRING and ARRAY[CHARACTER] should be mostly similar. If I can insert and remove characters from STRINGS, why not doing so with elements in...

Hello, as a starting point: Should we require that kernel classed may not inherit any class other than the specified? I mean "is an ARRAY a COLLECTION", and if...
... Hello, Arno. Actually, after Roger Browne took a break, it appears no one wanted to step into his large shoes and stand up with an agenda. So while you're...
... I think this is a question about the role of "implementation inheritance" in the Eiffel libraries, and that the fact that different librarians are free to...
... No, that precludes optimization and severely restricts a vendor. It would be enough if features not in the kernel definition would not be exported. -- Live...
... I think this is very hard and unnecessary. You have to take into account all kinds of operating systems. Gobo already has classes for the most common IO...
... Remember that any effort we do must have vendor support. I think it's completely unlikely that we get vendor support on either removing inheritance, or to...
