Historically, .Sy \&Dq \&Li was the preferred way before the deprecation of .Sy \&Li . .El .Ss EXAMPLES Section .Bl -dash -width "" .It Format the .Sx EXAMPLES section in the following way: .Bd -literal -offset indent \&.Bl -tag -width 0n \&.It Sy Example 1\\&: No Doing Something \&.Pp The following command does something. \&.Bd -literal -offset 2n \&.Li # Ic make -VLEGAL \&.Ed \&.It Sy Example 2\\&: No Doing Something Different \&.Pp The following command does something different. \&.Bd -literal -offset 2n \&.Li # Ic bectl list \&.Ed \&.Pp It is good to know this command. \&.El .Ed .Pp which renders as: .Bd -filled -offset indent .Bl -tag -width 0n .It Sy Example 1\&: No Doing Something .Pp The following command does something. .Bd -literal -offset 2n .Li # Ic make -VLEGAL .Ed .It Sy Example 2\&: No Doing Something Different .Pp The following command does something different. .Bd -literal -offset 2n .Li # Ic bectl list .Ed .Pp It is good to know this command. .El .Ed .El +.Ss Lists +.Bl -dash -width "" +.It +The +.Fl width +argument to the +.Sy \&.Bl +macro should match the length of the longest item in the list, e.g.: +.Bd -literal -offset indent +\&.Bl -tag -width "-a address" +\&.It Fl a Ar address +Set the address. +\&.It Fl v +Print the version. +\&.El +.Ed +.Pp +In case the longest item is too long and hurts readability, +the recommendation is to set +the +.Fl width +argument +to +.Ql indent , +e.g.: +.Bd -literal -offset indent +\&.Bl -tag -width "indent" +\&.It Cm build +Build the port. +\&.It Cm install +Install the port. +\&.It Fl install-missing-packages +Install the missing packages. +\&.El +.Ed +.El .Ss Synopsis Formatting .Bl -dash -width "" .It Do not put whitespace between alternative parameters separated with a pipe .Pq Dq | , e.g.: .Bd -literal -offset indent \&.Cm compression Cm on Ns | Ns Cm off \&.Cm install Fl -all Ns | Ns Ar portname Ar ... .Ed .Pp which in the SYNOPSIS section is rendered as: .Bd -unfilled -offset indent .Cm compression Cm on Ns | Ns Cm off .Cm install Fl -all Ns | Ns Ar portname Ar ... .Ed .It Use .Sy \&Cm to stylize characters that are command modifiers .Po e.g., .Dq \&, , .Dq @ or .Dq "=" .Pc . For example: .Bd -literal -offset indent \&.Sm off \&.Fl -meet Cm = Ar who Oo Cm \&, Ar who " " Ar "..." Oc Cm @ Ar where \&.Sm on .Ed .Pp which renders as: .Bd -filled -offset indent .Sm off .Fl -meet Cm = Ar who Oo Cm \&, Ar who " " Ar "..." Oc Cm @ Ar where .Sm on .Ed .Pp instead of: .Bd -literal -offset indent \&.Sm off \&.Fl -meet No = Ar who Oo , Ar who " " Ar "..." Oc @ Ar where \&.Sm on .Ed .Pp which would render as: .Bd -filled -offset indent .Sm off .Fl -meet No = Ar who Oo , Ar who " " Ar "..." Oc @ Ar where .Sm on .Ed .Pp It is important to realize that in the correct example, .Dq \&, , .Dq @ and .Dq = are stylized with .Sy \&Cm . At the same time, the square brackets .Pq Dq "[]" are not stylized as they do not belong to the syntax of the .Fl -meet flag. .El .Ss Quoting .Bl -dash -width "" .It Use the .Sy \&Dq .Pq Do Dc macro for quoting. Use the .Sy \&Sq .Pq So Sc macro for quoting inside quotes. The use of the .Sy \&Qq .Pq Qo Qc macro is usually not necessary. .El .Ss Variables .Bl -dash -width "" .It Use .Sy \&Va instead of .Sy \&Dv for .Xr sysctl 8 variables like .Va kdb.enter.panic . .It Use the angle brackets .Sy \&Aq .Pq Dq "<>" macro for arguments .Pq Sy \&Ar when they are mixed with similarly stylized macros like .Sy \&Pa or .Sy \&Va , e.g.: .Bd -literal -offset indent \&.Va critical_filesystems_ Ns Aq Ar type .Ed .Pp which renders as: .Bd -filled -offset indent .Va critical_filesystems_ Ns Aq Ar type .Ed .Pp instead of: .Bd -literal -offset indent \&.Va critical_filesystems_ Ns Ar type .Ed .Pp that would be rendered as: .Bd -filled -offset indent .Va critical_filesystems_ Ns Ar type .Ed .El .Sh SEE ALSO .Xr man 1 , .Xr mandoc 1 , .Xr mdoc 7 , .Xr style 9 .Sh HISTORY This manual page first appeared in .Fx 13.0 . .Sh AUTHORS .An Mateusz Piotrowski Aq Mt 0mp@FreeBSD.org
