17:08 Feature #385: Design new errors using inheritance: The (work in progress) list of errors is now in the documentation (cvs will help us getting to the final design)
@do... Anna Maria Bigatti
14:50 Feature #92: Error Codes: What is a reasonable syntax for adjoining a suppl mesg to an error object?
(A) Anna suggests a fn-call style: *@Inde... John Abbott
14:40 Feature #92: Error Codes: Note: our current thinking is to have only very few types of error, and allow each error object to contain a _supplem... John Abbott

15:28 Feature #385: Design new errors using inheritance: After a long discussion (yesterday) with Anna, we concluded that:
# we are too ignorant about catching/handling excep... John Abbott

14:24 Feature #385: Design new errors using inheritance: BOOST exceptions are quite sophisticated. Since exceptions currently play a very minor role in CoCoALib, *I am incli... John Abbott
12:10 Feature #385: Design new errors using inheritance: The following URL @http://stackoverflow.com/questions/9387377/how-to-design-exception-types-in-c@ suggests deriving a... John Abbott
11:18 Feature #385: Design new errors using inheritance: The current error mechanism allows for *error messages in different languages* -- and the user can change language ar... John Abbott
11:10 Feature #385 (In Progress): Design new errors using inheritance: So that C++'s *@try...catch@* mechanism can be used easily we should redesign CoCoALib's error codes so that they are... John Abbott

17:06 Feature #383: Resolution/morse: integrate Mario Albert's code into CoCoALib: The inclusion of Mario's code is essentially complete.
There are still several questions about its public interface.

19:05 Feature #383 (In Progress): Resolution/morse: integrate Mario Albert's code into CoCoALib: John and Mario have been incorporating his code into CoCoALib.
We have also cleaned the code somewhat. Perhaps Co... John Abbott
19:00 Feature #383 (In Progress): Resolution/morse: integrate Mario Albert's code into CoCoALib: Mario Albert has written an implementation for computing resolutions & Betti numbers.
Incorporate it into CoCoALib John Abbott

14:46 Design #377: IsDivisible -- exact semantics?: JAA continues to believe that attempting to compute @0/0@ in any ring should give an error. Giving an answer is almo... John Abbott

19:01 Feature #379 (Closed): Iter for subsets/tuples: Add new iters for subsets/tuples.
[JAA see file @ShortTerm/oscar.C@] John Abbott
10:57 Design #377 (In Progress): IsDivisible -- exact semantics?: The problem with dividing @4/2@ in @ZZ/6@ is that the true answer is @2@ in @ZZ/3@ -- a different ring! The answer ... John Abbott
10:28 Design #377 (Closed): IsDivisible -- exact semantics?: While dealing with issue #248 I realised that the exact semantics of @IsDivisible@ are not clear.
The problem is whe... John Abbott

23:05 Feature #203 (In Progress): Function to get the Hilbert Polynomial ring from GlobalManager: Now that we have *RingQQt(n)* clean up older tentatives.... Anna Maria Bigatti
