@ -14359,6 +14359,16 @@ names returned by @option{--list-checkers}.
Only disable the checkers specified in a comma-separated list using the
names returned by @option{--list-checkers}.
@item --expression=@var{expr}
@itemx -e @var{expr}
Consider the package @var{expr} evaluates to.
This is useful to unambiguously designate packages, as in this example:
@example
guix lint -c archival -e '(@@ (gnu packages guile) guile-3.0)'
@end example
@item --no-network
@itemx -n
Only enable the checkers that do not depend on Internet access.
