See set-gag-mode for a discussion of key checkpoints.
Examples:where each of; (Default) When a proof fails, print all key checkpoints before ; induction but at most 3 key checkpoints after induction: (set-checkpoint-summary-limit '(nil . 3) state)
; When a proof fails, print at most 3 key checkpoints before ; induction but all 3 key checkpoints after induction: (set-checkpoint-summary-limit '(3 . nil) state)
; When a proof fails, print at most 3 key checkpoints before ; induction and at most 5 key checkpoints after induction: (set-checkpoint-summary-limit '(3 . 5) state)
; When a proof fails, print all key checkpoints: (set-checkpoint-summary-limit '(nil . nil) state)
General Forms: (set-checkpoint-summary-limit '(n1 . n2) state) (set-checkpoint-summary-limit nil state)
n1 and n2 is a natural number or nil. For the
second form, nil is treated as '(nil . nil). The values n1 and
n2 determine printing of key checkpoints generated before the first
induction and generated after the first induction, respectively, where at
most n1 or n2 (respectively) such key checkpoints are printed unless
the value is nil, in which case there is no limitation.
