37: The arguments are as follows:
1.19 kristaps 38: .Bl -tag -width Ds
39: .It Fl m Ns Ar format
1.57 kristaps 40: Input format.
41: See
1.8 kristaps 42: .Sx Input Formats
1.57 kristaps 43: for available formats.
44: Defaults to

1.57 kristaps 47: Comma-separated output options.
1.19 kristaps 48: .It Fl T Ns Ar output
1.57 kristaps 49: Output format.
50: See
1.1 kristaps 51: .Sx Output Formats
1.57 kristaps 52: for available formats.
53: Defaults to
1.58 kristaps 54: .Fl T Ns Cm ascii .
1.1 kristaps 55: .It Fl V
56: Print version and exit.
1.77 schwarze 57: .It Fl W Ns Ar level
58: Specify the minimum message
59: .Ar level
60: to be reported on the standard error output and to affect the exit status.
61: The
62: .Ar level
63: can be
64: .Cm warning ,
65: .Cm error ,
66: or
67: .Cm fatal .
68: The default is
69: .Fl W Ns Cm fatal ;
1.58 kristaps 70: .Fl W Ns Cm all
1.77 schwarze 71: is an alias for
72: .Fl W Ns Cm warning .
73: See
74: .Sx EXIT STATUS
75: and
76: .Sx DIAGNOSTICS
77: for details.
78: .Pp
79: The special option
80: .Fl W Ns Cm stop
81: tells
82: .Nm
83: to exit after parsing a file that causes warnings or errors of at least
84: the requested level.
85: No formatted output will be produced from that file.
86: If both a
87: .Ar level
88: and
89: .Cm stop
90: are requested, they can be joined with a comma, for example
91: .Fl W Ns Cm error , Ns Cm stop .
1.58 kristaps 92: .It Ar file
93: Read input from zero or more files.
1.57 kristaps 94: If unspecified, reads from stdin.
95: If multiple files are specified,
1.2 kristaps 96: .Nm
97: will halt with the first failed parse.
1.1 kristaps 98: .El
99: .Pp
1.26 kristaps 100: By default,
101: .Nm
102: reads
1.8 kristaps 103: .Xr mdoc 7
1.12 kristaps 104: or
105: .Xr man 7
1.8 kristaps 106: text from stdin, implying
1.58 kristaps 107: .Fl m Ns Cm andoc ,
1.48 kristaps 108: and produces
1.58 kristaps 109: .Fl T Ns Cm ascii
1.48 kristaps 110: output.
1.8 kristaps 111: .Ss Input Formats
112: The
113: .Nm

115: .Xr mdoc 7
116: and

1.58 kristaps 119: .Fl m Ns Cm doc
1.8 kristaps 120: and
1.58 kristaps 121: .Fl m Ns Cm an ,
1.57 kristaps 122: respectively.
123: The
1.8 kristaps 124: .Xr mdoc 7
125: format is
126: .Em strongly
1.26 kristaps 127: recommended;
1.8 kristaps 128: .Xr man 7
129: should only be used for legacy manuals.
1.11 kristaps 130: .Pp
1.12 kristaps 131: A third option,
1.58 kristaps 132: .Fl m Ns Cm andoc ,
1.13 kristaps 133: which is also the default, determines encoding on-the-fly: if the first
1.26 kristaps 134: non-comment macro is
1.27 kristaps 135: .Sq \&Dd
1.13 kristaps 136: or
1.27 kristaps 137: .Sq \&Dt ,
1.26 kristaps 138: the
1.13 kristaps 139: .Xr mdoc 7
140: parser is used; otherwise, the
141: .Xr man 7
142: parser is used.
143: .Pp
144: If multiple
1.26 kristaps 145: files are specified with
1.58 kristaps 146: .Fl m Ns Cm andoc ,
1.57 kristaps 147: each has its file-type determined this way.
148: If multiple files are
1.13 kristaps 149: specified and
1.58 kristaps 150: .Fl m Ns Cm doc
1.12 kristaps 151: or
1.58 kristaps 152: .Fl m Ns Cm an
1.12 kristaps 153: is specified, then this format is used exclusively.

421: The parser is unable to parse a given input file at all.
422: No formatted output is produced from that input file.
423: .It Cm error
424: An input file contains syntax that cannot be safely interpreted,
425: either because it is invalid or because
426: .Nm
427: does not implement it yet.
428: By discarding part of the input or inserting missing tokens,
429: the parser is able to continue, and the error does not prevent
430: generation of formatted output, but typically, preparing that
431: output involves information loss, broken document structure
432: or unintended formatting.
433: .It Cm warning
434: An input file uses obsolete, discouraged or non-portable syntax.
435: All the same, the meaning of the input is unambiguous and a correct
