NAME

6       HTML::Lint::Error - Error object for the Lint functionality
7

SYNOPSIS

9       See HTML::Lint for all the gory details.
10

EXPORTS

12       None.  It's all object-based.
13

METHODS

15       Almost everything is an accessor.
16

Error types: "STRUCTURE", "HELPER", "FLUFF"

18       Each error has a type.  Note that these roughly, but not exactly, go
19       from most severe to least severe.
20
21       ·   "STRUCTURE"
22
23           For problems that relate to the structural validity of the code.
24           Examples: Unclosed <TABLE> tags, incorrect values for attributes,
25           and repeated attributes.
26
27       ·   "HELPER"
28
29           Helpers are notes that will help you with your HTML, or that will
30           help the browser render the code better or faster.  Example:
31           Missing HEIGHT and WIDTH attributes in an IMG tag.
32
33       ·   "FLUFF"
34
35           Fluff is for items that don't hurt your page, but don't help it
36           either.  This is usually something like an unknown attribute on a
37           tag.
38
39   new()
40       Create an object.  It's not very exciting.
41
42   is_type( $type1 [, $type2 ] )
43       Tells if any of $type1, $type2... match the error's type.  Returns the
44       type that matched.
45
46           if ( $err->is_type( HTML::Lint::Error::STRUCTURE ) ) {....
47
48   where()
49       Returns a formatted string that describes where in the file the error
50       has occurred.
51
52       For example,
53
54           (14:23)
55
56       for line 14, column 23.
57
58       The terrible thing about this function is that it's both a plain ol'
59       formatting function as in
60
61           my $str = where( 14, 23 );
62
63       AND it's an object method, as in:
64
65           my $str = $error->where();
66
67       I don't know what I was thinking when I set it up this way, but it's
68       bad practice.
69
70   as_string()
71       Returns a nicely-formatted string for printing out to stdout or some
72       similar user thing.
73
74   file()
75       Returns the filename of the error, as set by the caller.
76
77   line()
78       Returns the line number of the error.
79
80   column()
81       Returns the column number, starting from 0
82
83   errcode()
84       Returns the HTML::Lint error code.  Don't rely on this, because it will
85       probably go away.
86
87   errtext()
88       Descriptive text of the error
89
90   type()
91       Type of the error
92

POSSIBLE ERRORS

94       Each possible error in HTML::Lint has a code.  These codes are used to
95       identify each error for when you need to turn off error checking for a
96       specific error.
97
98   api-parse-not-called
99       You called the "errors()" method before calling "parse()" and "eof()".
100
101   api-eof-not-called
102       You called the "errors()" method before calling "eof()".
103
104   config-unknown-directive
105       Unknown directive "DIRECTIVE"
106
107       You specified a directive in a comment for HTML::Lint that it didn't
108       recognize.
109
110   config-unknown-value
111       Unknown value "VALUE" for DIRECTIVE directive
112
113       Directive values can only be "on", "off", "yes", "no", "true", "false",
114       "0" and "1".
115
116   elem-unknown
117       HTML::Lint doesn't know recognize the tag.
118
119   elem-unopened
120       "</tag>" with no opening "<tag>".
121
122   elem-unclosed
123       "<tag>" at WHERE is never closed.
124
125   elem-empty-but-closed
126       "<tag>" is not a container -- "</tag>" is not allowed.
127
128   elem-img-alt-missing
129       "<img src="FILENAME.PNG">" does not have ALT text defined.
130
131   elem-img-sizes-missing

133
134   elem-nonrepeatable
135       "<tag>" is not repeatable, but already appeared at WHERE.
136
137   doc-tag-required
138       "<tag>" tag is required.
139
140   attr-repeated
141       ATTR attribute in "<tag>" is repeated.
142
143   attr-unknown
144       Unknown attribute "ATTR" for tag "<tag>".
145
146   text-unclosed-entity
147       Entity ENTITY is missing its closing semicolon
148
149   text-unknown-entity
150       Entity ENTITY is unknown
