CHECKNR(1) User Commands CHECKNR(1)

NAME

checknr - check nroff and troff input files; report possible errors

SYNOPSIS

checknr [-fs] [-a . x1 . y1 . x2 . y2 ... .xn .yn]
[-c . x1 . x2 . x3 ... .xn] [filename]...

DESCRIPTION

checknr checks a list of nroff(1) or troff(1) input files for certain
kinds of errors involving mismatched opening and closing delimiters
and unknown commands. If no files are specified, checknr checks the
standard input. Delimiters checked are:

o Font changes using \fx ... \fP.

o Size changes using \sx ... \s0.

o Macros that come in open ... close forms, for example, the
.TS and


checknr knows about the ms(7) and me(7) macro packages.


checknr is intended to be used on documents that are prepared with
checknr in mind. It expects a certain document writing style for \f
and \s commands, in that each \fx must be terminated with \fP and
each \sx must be terminated with \s0. 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 checknr. Since it is probably
better to use the \fP and \s0 forms anyway, you should think of this
as a contribution to your document preparation style.

OPTIONS

-f
Ignore \f font changes.


-s
Ignore \s size changes.


-a .x1 .y1...
Add pairs of macros to the list. The pairs of
macros are assumed to be those (such as .DS
and .DE) that should be checked for balance.
The -a option 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 `-a.BS.ES'


-c .x1...
Define commands which checknr would otherwise
complain about as undefined.

BUGS

There is no way to define a one-character macro name using the -a
option.
