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.

Created new fn *@SpecializeToListOfRingElem@* which converts a generic @LIST@ into a list of @RINGELEM@ (I hope).

Create new type for representing sparse matrices.
Then check all code which by default creates a @DenseMat@ (becau... John Abbott

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@.

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

15:30 CoCoALib Feature #1598: RingHom: implement phi(X) as apply(phi, X) also for X vector and matrix

I'll try doing it!
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"?
