\DOC verbose
\TYPE {verbose : bool ref}
\SYNOPSIS
Flag to control verbosity of informative output.
\DESCRIBE
When the value of {verbose} is set to {true}, the function {remark} will output
its string argument whenever called. This is used for most informative output
in automated rules.
\FAILURE
Not applicable.
\EXAMPLE
Consider this call MESON to prove a first-order formula:
{
# MESON[] `!f g:num->num. (?!x. x = g(f(x))) <=> (?!y. y = f(g(y)))`;;
0..0..1..solved at 4
CPU time (user): 0.01
0..0..1..2..6..11..19..28..37..46..94..151..247..366..584..849..solved at 969
CPU time (user): 0.12
0..0..1..solved at 4
CPU time (user): 0.
0..0..1..2..6..11..19..28..37..46..94..151..247..366..584..849..solved at 969
CPU time (user): 0.06
val it : thm = |- !f g. (?!x. x = g (f x)) <=> (?!y. y = f (g y))
}
\noindent By changing the verbosity level, most of the output disappears:
{
# verbose := false;;
val it : unit = ()
# MESON[] `!f g:num->num. (?!x. x = g(f(x))) <=> (?!y. y = f(g(y)))`;;
CPU time (user): 0.01
CPU time (user): 0.13
CPU time (user): 0.
CPU time (user): 0.081
val it : thm = |- !f g. (?!x. x = g (f x)) <=> (?!y. y = f (g y))
}
\noindent and if we also disable timing reporting the action is silent:
{
# report_timing := false;;
val it : unit = ()
# MESON[] `!f g:num->num. (?!x. x = g(f(x))) <=> (?!y. y = f(g(y)))`;;
val it : thm = |- !f g. (?!x. x = g (f x)) <=> (?!y. y = f (g y))
}
\SEEALSO
remark, report_timing.
