10:17 Feature #1271 (In Progress): Allow Interruption of printing?: Which printing commands should allow themselves to be interrupted?
* lists
* matrices
* ideals (?)
I think prob... John Abbott
08:26 Feature #1271: Allow Interruption of printing?: I agree this would be very useful.
Strange for the error! Anna Maria Bigatti

17:49 Feature #1271: Allow Interruption of printing?: I have a tried a first approach, but it did no work as I would have liked...
What I tried:

17:43 Feature #1271 (In Progress): Allow Interruption of printing?: Inside emacs, if you print out a very long list then it takes ages before you can use emacs/CoCoA-5 again.
Conside... John Abbott

20:56 Slug #1270: RationalSolve: use MinPolyQuot instead of elim: Before we decide to replace @elim@ by @MinPolyQuot@ we should check that @MinPolyQuot@ is usually faster (I would cer... John Abbott
20:19 Slug #1270 (Closed): RationalSolve: use MinPolyQuot instead of elim: Currently @RationalSolve@ uses @elim@, but every use is equivalent to a call to @MinPolyQuot@ (in the subring generat... John Abbott

17:14 Support #1268: Documentation for how to write a CoCoA package: I can make some notes based on the questions I've been asked.
These notes could form a basis for a better guide; b... John Abbott
17:12 Support #1268 (Closed): Documentation for how to write a CoCoA package: Some students here in Passau have been given the task of writing a CoCoA package, and have asked me for guidance. It... John Abbott
17:11 Design #474 (In Progress): Eliminate package BinRepr: What is the status of this issue?
The package still exists, and there is a *@BinRepr@* builtin function.
Can we d... John Abbott
17:08 Feature #1012 (Closed): Chebyshev polynomials: This has already been done. Closing. John Abbott

21:52 Feature #1262: Split BuiltinFunctions-CoCoALib.C into smaller files: Anna has just sent me some code with redundant @#include@ directives removed.
Most compilation times are the same. ... John Abbott
11:50 Feature #1262: Split BuiltinFunctions-CoCoALib.C into smaller files: I believe that built-in functions (for extlibs, at least) are "registered" by constructing a global object. So the a... John Abbott

17:30 Feature #1262: Split BuiltinFunctions-CoCoALib.C into smaller files: Indeed "duplication" is generally undesirable (as is the use of @goto@), but it may still be a good idea in certain "... John Abbott

15:23 Feature #1262: Split BuiltinFunctions-CoCoALib.C into smaller files: I suggest putting @DECLARE_MISSING_EXTLIB@ into a smaller header file (if possible).
Then files such as @BuiltinFu... John Abbott
14:23 Feature #1262: Split BuiltinFunctions-CoCoALib.C into smaller files: It seems that many includes in @BuiltInFunctions.H@ are useless, or useful for only a few functions. Cleaning them m... Anna Maria Bigatti
14:16 Feature #1262: Split BuiltinFunctions-CoCoALib.C into smaller files: I note also that my compilation test above was without any external libraries.

10:58 Feature #1262: Split BuiltinFunctions-CoCoALib.C into smaller files: The time to compile (and link) @ex-empty.C@ was about 20s.

13:53 Feature #1262: Split BuiltinFunctions-CoCoALib.C into smaller files: I had a look.
I think it would make sense to separate off the functions with variable number of args.

A possible solution could be to print "weird characters" using backslash+octa... John Abbott
