show_tags : bool ref
STRUCTURE
SYNOPSIS
Flag for controlling display of tags in theorem prettyprinter.
DESCRIPTION
The flag show_tags controls the display of values of type thm. When set to true, the tag attached to a theorem will be printed when the theorem is printed. When set to false, no indication of the presence or absence of a tag will be displayed.
EXAMPLE
- show_tags := false;
> val it = () : unit

- pairTheory.PAIR_MAP_THM;
> val it = |- !f g x y. (f ## g) (x,y) = (f x,g y) : thm

- mk_thm ([],F);
> val it = |- F : thm

- show_tags := true;
> val it = () : unit

- pairTheory.PAIR_MAP_THM;
> val it = [oracles: ] [axioms: ] [] |- !f g x y. (f ## g) (x,y) = (f x,g y)
    : thm

- mk_thm ([],F);
> val it = [oracles: MK_THM] [axioms: ] [] |- F : thm

COMMENTS
The initial value of show_tags is false.
