12:37 CoCoALib Design #1156: Printing for RingElem: Part of the motivation is that it seems to be tricky to resolve issue #930 about printing out TwinFloat values as pol... John Abbott
12:30 CoCoALib Design #1156 (New): Printing for RingElem: JAA would like to reconsider the design of printing for @RingElem@ because the current design is rather inelegant. John Abbott
12:28 CoCoA-5 Bug #1152: Release: problems with sed: *(A)* The simplest solution is to call @sed@ directly without using its full path:
* *@+++@* should work everywhere
... John Abbott

21:10 CoCoALib Feature #1154: SmallFpImpl: new ctor arg to say do-not-check-that-arg-is-prime: Another posibility is for a "prime source" to produce values of a new type @SmallPrime@ (which is really just a @long... John Abbott
20:52 CoCoALib Feature #1154: SmallFpImpl: new ctor arg to say do-not-check-that-arg-is-prime: Several CRT loops look a lot like this:... John Abbott
20:49 CoCoALib Feature #1154 (Closed): SmallFpImpl: new ctor arg to say do-not-check-that-arg-is-prime: I propose adding a new ctor for @SmallFpImpl@ where the caller can use a flag to guarantee that the arg is prime.
... John Abbott
21:02 CoCoALib Feature #1155: Create a new "prime source" iterator: Add a new class to CoCoALib for generating primes in succession -- for use inside CRT loops.
Currently a CRT loop ... John Abbott
20:55 CoCoALib Feature #1155 (Closed): Create a new "prime source" iterator: In CoCoA-4 the old factorizer code had an "iterator" for generating primes in succession.
Add such an object to Co... John Abbott

08:08 CoCoA-5 Feature #1153 (New): New function: gin for algebraic extensions: Think of theory and implement @gin@ for algebraic extensions Anna Maria Bigatti
07:40 CoCoA-5 Bug #1152 (Closed): Release: problems with sed: For some compilations there are problems with the path for @sed@.
Anna Maria Bigatti

13:55 CoCoALib Feature #1115 (In Progress): New class: exterior algebra: Anna Maria Bigatti
13:48 CoCoALib Feature #1115: New class: exterior algebra: JAA has made a first impl (mostly copying code from @RingWeyl@). Many fns are still NYI.
Anna, Michele and Elisa ... John Abbott

15:28 CoCoA-5 Feature #368: port SmithNormalForm (CoCoA-4)package to CoCoA-5: This should be ported to CoCoALib (once it has been corrected). It would surely be faster ;-)
John Abbott
15:27 CoCoA-5 Feature #368: port SmithNormalForm (CoCoA-4)package to CoCoA-5: More failing examples:... John Abbott
15:23 CoCoA-5 Feature #368 (In Progress): port SmithNormalForm (CoCoA-4)package to CoCoA-5: Anna says she has "cleaned up" the original CoCoA-4 code so that CoCoA-5 accepts it.
The code is in @MatNormalForm.c... John Abbott

17:32 CoCoA-5 Design #1151: ConcatList or ConcatLists: Personally I find the name @ConcatLists@ more "natural" because it concatenates many lists.
The fns @ConcatVerList... John Abbott
17:19 CoCoA-5 Design #1151 (In Progress): ConcatList or ConcatLists: The reason why the builtin function is called ...List is that this is the naming convention for functions operating o... Anna Maria Bigatti
17:12 CoCoA-5 Design #1151: ConcatList or ConcatLists: In the current version (5.2.2) the fn *@ConcatList@* is built-in, while *@ConcatLists@* is defined in @list.cpkg5@ an... John Abbott
17:06 CoCoA-5 Design #1151 (Closed): ConcatList or ConcatLists: CoCoA-5 has both *@ConcatList@* and *@ConcatLists@*. They are identical.
We should keep just one.
*2021-01* De... John Abbott
15:05 CoCoALib Support #1149: Release: CoCoALib-0.99600 (together with CoCoA-5.2.4): Principal changes and additions to CoCoALib:
* ctors for *@BigInt@* and *@BigRat@* from *@string@* and GMP native ob... John Abbott

18:30 CoCoALib Feature #1150 (New): New fn: transform ideal with ring hom: Do we want a new fun for transforming an ideal with a ringhom?
@TransformIdeal(const ideal& I, const RingHom& phi)@
... John Abbott
15:39 CoCoA-5 Design #1120: Web site: If I visit the CoCoA web site using Firefox in "private mode" then the page never finishes loading because the rectan... John Abbott

14:33 CoCoALib Design #925: MachineInt or long for args which are indices (yet again): Should indices be constrained to be non-negative?
Note that @symbol@ currently does allow negative "indices".
It ... John Abbott

16:09 CoCoALib Feature #872: LinSolve for matrices over FFp: I have implemented a version of "LinDepMill" for MatrixFp.
This should be a good basis for further impls.
Note ha... John Abbott

12:09 CoCoALib Support #1056 (Closed): Release: CoCoALib-0.99560 (together with CoCoA-5.2.2): Anna Maria Bigatti
12:05 CoCoA-5 Support #1061 (Closed): Release: CoCoA-5.2.2: Anna Maria Bigatti
12:02 CoCoALib Support #1149 (Closed): Release: CoCoALib-0.99600 (together with CoCoA-5.2.4): Everything related to making a CoCoALib release:
# Redmine Roadmap: close or postpone issue
# Redmine Release iss... Anna Maria Bigatti
11:58 CoCoA-5 Support #1148 (Closed): Release CoCoA-5.2.4: Everything for the release
# Redmine Roadmap: close or postpone issue
# Redmine Release issues: check percentages... Anna Maria Bigatti
11:56 CoCoALib Design #1147: mySquare and myPowerSmallExp: The advantage of having @mySquare@ private is that we do not need to do arg checking, and there is (perhaps?) no need... John Abbott
11:08 CoCoALib Design #1147 (New): mySquare and myPowerSmallExp: Check the interrelation between @RingBase::MySquare@ and @RingBase::myPowerSmallExp@.
In particular should @mySqua... John Abbott
11:44 CoCoA-5 Bug #275 (Closed): Unhelpful error messages when SmallExponent_t is unsigned char.: I think I have solved all problems John Abbott
