SET-DEFERRED-TTAG-NOTES.html -- ACL2 Version 6.3

## SET-DEFERRED-TTAG-NOTES

modify the verbosity of `TTAG NOTE` printing

    Major Section:  SWITCHES-PARAMETERS-AND-MODES

    General Form:
    (set-deferred-ttag-notes val state)

where `val` is `t` or `nil`.

See defttag for a discussion of trust tags (ttags). By default, a ```TTAG NOTE`'' is printed in order to indicate reliance on a ttag. When many such notes are printed, it may be desirable to avoid seeing them all. Upon evaluation of the form

    (set-deferred-ttag-notes t state)

ACL2 will enter a deferred mode for the printing of ttag notes. In this mode, only the first ttag note is printed for each top-level command, and the remainder are summarized before the next top-level prompt (if any) is printed, hence before the next command is evaluated. That summary is merely a list of ttags, but the summary explains that the full ttag notes may be printed with the command `(show-ttag-notes)`.

Note that `(show-ttag-notes)` spares you duplicate ttag notes. If you want to see every ttag note as it would normally appear, for maximum security, do not evaluate the command `(set-deferred-ttag-notes t state)`. You can undo the effect of this command, returning to an immediate mode for printing ttag notes, by evaluating:

    (set-deferred-ttag-notes nil state)
