35: The

38: .Dq mdoc
39: manual page for display on the terminal. The arguments are as follows:
1.15 kristaps 40: .Bl -tag -width XXXXXXXXXXXX
1.1 kristaps 41: .\" ITEM
42: .It Fl v
43: Print verbose parsing output.
44: .\" ITEM

49: Override default compiler behaviour. See
50: .Sx Compiler Options
51: for details.
52: .\" ITEM
1.1 kristaps 53: .It Fl W Ns Ar err...
54: Print warning messages. May be set to
55: .Fl W Ns Ar all
56: for all warnings,
57: .Ar compat
58: for groff/troff-compatibility warnings, or
59: .Ar syntax
60: for syntax warnings. If
61: .Fl W Ns Ar error
62: is specified, warnings are considered errors and cause utility
63: termination. Multiple
64: .Fl W
65: arguments may be comma-separated, such as
66: .Fl W Ns Ar error,all .
67: .\" ITEM
68: .It Ar infile

1.1 kristaps 77: The
78: .Nm
79: utility is a formatting front-end for
80: .Xr mdoc 3 ,
81: which parses the
82: .Dq mdoc
83: input, documented at
84: .Xr mdoc 7
85: and
86: .Xr mdoc.samples 7 ,
1.15 kristaps 87: into an abstract syntax tree.
1.1 kristaps 88: .Pp
1.15 kristaps 89: By default,
90: .Nm
91: reads from stdin and prints ANSI
92: .Qq raw
93: terminal-encoded output to stdout, at this time to a fixed column with
94: of 78 characters.

100: Default compiler behaviour may be overriden with the
101: .Fl f
102: flag. The available options are as follows:
103: .Bl -tag -width XXXXXXXXXXXX -offset XXXX
104: .It Fl f Ns Ar ign-scope
105: When rewinding the scope of a block macro, forces the compiler to ignore
106: scope violations. This can seriously mangle the resulting tree.
107: .It Fl f Ns Ar ign-escape
108: Ignore invalid escape sequences.
1.16 ! kristaps 109: .It Fl f Ns Ar ign-macro
! 110: Ignore unknown macros at the start of input lines.

1.15 kristaps 114: As with the

118: options may be grouped and delimited with a comma. Using
119: .Fl f Ns Ar ign-scope,ign-escape ,
