CHECKNR(1)                                                          CHECKNR(1)


NAME
       checknr - check nroff/troff files

SYNOPSIS
       checknr  [ -s ] [ -f ] [ -a.x1.y1.x2.y2. ... .xn.yn ] [ -c.x1.x2.x3 ...
       .xn ] [ file ...  ]

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  stan‐
       dard input.  Delimeters checked are:

       (1)    Font changes using \fx ... \fP.

       (2)    Size changes using \sx ... \s0.

       (3)    Macros  that  come in open ... close forms, for example, the .TS
              and .TE macros which must always come in pairs.

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

       Additional pairs of macros can be  added  to  the  list  using  the  -a
       option.   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 -a.BS.ES

       The -c option defines commands  which  would  otherwise  be  complained
       about as undefined.

       The -f option requests checknr to ignore \f font changes.

       The -s option requests checknr to ignore \s size changes.

       Checknr  is  intended  to  be  used on documents that are prepared with
       checknr in mind, much the same as lint.  It expects a certain  document
       writing  style  for \f and \s commands, in that each \fx must be termi‐
       nated 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 origi‐
       nal 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.

DIAGNOSTICS
       Complaints about unmatched delimiters.
       Complaints about unrecognized commands.
       Various complaints about the syntax of commands.

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