50: .Sh DESCRIPTION
1.4 ! aaron 51: .Nm checknr
1.1 deraadt 52: checks a list of
53: .Xr nroff 1
54: or
55: .Xr troff 1
56: input files for certain kinds of errors
57: involving mismatched opening and closing delimiters
58: and unknown commands.
59: If no files are specified,
60: .Nm checknr
61: checks the standard input.
62: .Pp
63: Options:
64: .Bl -tag -width Ds
65: .It Fl a
66: Add additional pairs of macros to the list of known macros.
67: This must be followed by groups of six characters, each group defining
68: a pair of macros.
69: The six characters are
70: a period,
71: the first macro name,
72: another period,
73: and the second macro name.
74: For example, to define a pair .BS and .ES, use
75: .Sq Li \-a.BS.ES
76: .It Fl c
77: Define commands which would otherwise be complained about
78: as undefined.
79: .It Fl f
80: Request
81: .Nm checknr
82: to ignore
83: .Ql \ef
84: font changes.
85: .It Fl s
86: Ignore
87: .Ql \es
88: size changes.
89: .El
90: .Pp
91: Delimiters checked are:
92: .Bl -enum
93: .It
94: Font changes using \efx ... \efP.
95: .It
96: Size changes using \esx ... \es0.
97: .It
98: Macros that come in open ... close forms, for example,
99: the .TS and .TE macros which must always come in pairs.
100: .El
101: .Pp
1.4 ! aaron 102: .Nm checknr
1.1 deraadt 103: is intended for use on documents that are prepared with
104: .Nm checknr
105: in mind, much the same as
106: .Xr lint 1 .
107: It expects a certain document writing style for
108: .Ql \ef
109: and
110: .Ql \es
111: commands,
112: in that each
113: .Ql \efx
114: must be terminated with
115: .Ql \efP
116: and
117: each
118: .Ql \esx
119: must be terminated with
120: .Ql \es0 .
121: While it will work to directly go into the next font or explicitly
122: specify the original font or point size,
123: and many existing documents actually do this,
124: such a practice will produce complaints from
125: .Nm checknr .
126: Since it is probably better to use the
127: .Ql \efP
128: and
129: .Ql \es0
130: forms anyway,
131: you should think of this as a contribution to your document
132: preparation style.
133: .Pp

136: .Xr ms 7
137: and

139: macro packages.

146: .Bd -ragged -compact
147: Complaints about unmatched delimiters.
148: Complaints about unrecognized commands.
149: Various complaints about the syntax of commands.
150: .Ed
151: .Sh BUGS
152: There is no way to define a 1 character macro name using
153: .Fl a .
154: .Pp
155: Does not correctly recognize certain reasonable constructs,
156: such as conditionals.
157: .Sh HISTORY
158: The
159: .Nm
160: command appeared in
161: .Bx 4.0 .
