#342 closed bug (wontfix)

Type of list prints the list

Reported by: zteitler Owned by: somebody
Priority: minor Milestone: 3-1-4 and higher
Component: dontKnow Version: 3-1-3
Keywords: Cc:


When L is a list, I expect type(L) to simply say "list". However Singular will also print the list. This is undesired (if the user wants the list to be printed, it can be requested by "print" rather than by "type"). Here is a sample session:

zteitler$ Singular
                     SINGULAR                                 /
 A Computer Algebra System for Polynomial Computations       /   version 3-1-3

> int a = 5;
> int b = 6;
> list L = a,b;
> type(L);
// L                    [0]  list, size: 2

Here is what I would like:

> type(L);
// L                    [0]  list, size: 2

(no other output).

It occurs to me that for other variable types, e.g. intmat, the value of the variable is printed by "type". So this is actually the designed behavior, I should not have entered it as a bug. Sorry.

I would like to request that "type" and "print" should be two separate commands, and "type" should not imply "print". In particular if a variable turns out to have a very large list or intmat, it can be disruptive to print it when I only want to see the type.

Could you please try using 'typeof' instead of 'type' (which does exactly what is written in the manual)?

Thank you for the suggestion. 'typeof' has the behavior that I was looking for. In the future I should use 'typeof' rather than 'type'.
