17:27 CoCoALib Feature #1598: RingHom: implement phi(X) as apply(phi, X) also for X vector and matrix: I made a prototype for matrix. Needs to be tested properly. Anna Maria Bigatti
17:27 CoCoA-5 Bug #946: Function "ideal" evaluates the argument twice: Just 1 left: @ModuleElem@
Relevant source seems to be in @BuiltinFunctions-CoCoALib.C@ around line 1465.
At the m... John Abbott
16:20 CoCoA-5 Bug #946: Function "ideal" evaluates the argument twice: Created new fn *@SpecializeToListOfRingElem@* which converts a generic @LIST@ into a list of @RINGELEM@ (I hope).

16:17 CoCoA-5 Bug #946: Function "ideal" evaluates the argument twice: at the end of this file there is a section "TO BE FIXED" with the last few cases to be fixed.

17:26 CoCoALib Feature #1602 (New): Sparse matrix (SparseMat): Create new type for representing sparse matrices.
Then check all code which by default creates a @DenseMat@ (becau... John Abbott
15:52 CoCoA-5 Feature #1599 (Resolved): ConcatStr: Renamed to *@ConcatStrings@*.
Very clear.

15:35 CoCoALib Bug #1473 (Feedback): isystem not working as expected: Anna says it works.
It is just a cheap hack: if @uname@ gives @Darwin@ then it uses @-I@ instead of @-isystem@.

15:47 CoCoALib Bug #1473: isystem not working as expected: I have a first prototype. Works on my Linux box (but hen it also worked before...)
I'll ask Anna to check on her ... John Abbott

17:47 CoCoA-5 Feature #1587: Multiline string literals (again): I am still inclined *against* multi-line string literals.
@NewFold@ above @ConcatStrings@ seem like a reasonable com... John Abbott
16:50 CoCoA-5 Feature #1599: ConcatStr: The fn maps a list of strings to a string by concatenation.
Should the fn be called *@ConcatStr@* or *@ConcatStrs@*? John Abbott

and think of other involved classes.
(and consider whether making apply obsolescent) Anna Maria Bigatti
15:23 CoCoALib Feature #1598 (In Progress): RingHom: implement phi(X) as apply(phi, X) also for X vector and matrix: Do we still want to keep *@apply@*?
Or should it be moved to "obsolescent"?

16:28 CoCoALib Bug #1601 (Closed): Compilation ambiguity: I have looked better at Florian's problem (in issue #1600).
The cause of the trouble is that the compiler prefers to... John Abbott

My understanding is that he... John Abbott

15:04 CoCoA-5 Feature #1599 (In Progress): ConcatStr: I already have an impl (see #1587#note-6 and #1431#note-9).
I think it could be useful. The only doubt I have c... John Abbott

18:09 CoCoALib Feature #1598 (Closed): RingHom: implement phi(X) as apply(phi, X) also for X vector and matrix: phi(f) is equivalent to apply(phi, f).
Implement also for matrix and vector (and export it to CoCoA-5) Anna Maria Bigatti
