.Sh DESCRIPTION
|
|
.Nm Checknr
|
|
checks a list of
|
|
.Xr nroff 1
|
|
or
|
|
.Xr troff 1
|
|
input files for certain kinds of errors
|
|
involving mismatched opening and closing delimiters
|
|
and unknown commands.
|
|
If no files are specified,
|
|
.Nm
|
|
checks the standard input.
|
|
.Pp
|
|
Options:
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
Add additional pairs of macros to the list of known macros.
|
|
This must be followed by groups of six characters, each group defining
|
|
a pair of macros.
|
|
The six characters are
|
|
a period,
|
|
the first macro name,
|
|
another period,
|
|
and the second macro name.
|
|
For example, to define a pair .BS and .ES, use
|
|
.Sq Li \-a.BS.ES
|
|
.It Fl c
|
|
Define commands which would otherwise be complained about
|
|
as undefined.
|
|
.It Fl f
|
|
Request
|
|
.Nm
|
|
to ignore
|
|
.Ql \ef
|
|
font changes.
|
|
.It Fl s
|
|
Ignore
|
|
.Ql \es
|
|
size changes.
|
|
.El
|
|
.Pp
|
|
Delimiters checked are:
|
|
.Bl -enum
|
|
.It
|
|
Font changes using \efx ... \efP.
|
|
.It
|
|
Size changes using \esx ... \es0.
|
|
.It
|
|
Macros that come in open ... close forms, for example,
|
|
the .TS and .TE macros which must always come in pairs.
|
|
.El
|
|
.Pp
|
|
.Nm Checknr
|
|
is intended for use on documents that are prepared with
|
|
.Nm
|
|
in mind, much the same as
|
|
.Xr lint 1 .
|
|
It expects a certain document writing style for
|
|
.Ql \ef
|
|
and
|
|
.Ql \es
|
|
commands,
|
|
in that each
|
|
.Ql \efx
|
|
must be terminated with
|
|
.Ql \efP
|
|
and
|
|
each
|
|
.Ql \esx
|
|
must be terminated with
|
|
.Ql \es0 .
|
|
While it will work to directly go into the next font or explicitly
|
|
specify the original font or point size,
|
|
and many existing documents actually do this,
|
|
such a practice will produce complaints from
|
|
.Nm .
|
|
Since it is probably better to use the
|
|
.Ql \efP
|
|
and
|
|
.Ql \es0
|
|
forms anyway,
|
|
you should think of this as a contribution to your document
|
|
preparation style.

.Xr ms 7

.Sh DIAGNOSTICS
|
|
.Bd -ragged -compact
|
|
Complaints about unmatched delimiters.
|
|
Complaints about unrecognized commands.
|
|
Various complaints about the syntax of commands.

|
.Ed
|
|
.Sh BUGS
|
|
There is no way to define a 1 character macro name using
|
|
.Fl a .
|
|
.Pp
|
|
Does not correctly recognize certain reasonable constructs,
|
|
such as conditionals.
