HTML::Lint::Error(3) User Contributed Perl Documentation HTML::Lint::Error(3)NAMEHTML::Lint::Error - Error object for the Lint functionality
SYNOPSIS
See HTML::Lint for all the gory details.
EXPORTS
None. It's all object-based.
METHODS
Almost everything is an accessor.
Error types: "STRUCTURE", "HELPER", "FLUFF"
Each error has a type. Note that these roughly, but not exactly, go
from most severe to least severe.
· "STRUCTURE"
For problems that relate to the structural validity of the code.
Examples: Unclosed <TABLE> tags, incorrect values for attributes,
and repeated attributes.
· "HELPER"
Helpers are notes that will help you with your HTML, or that will
help the browser render the code better or faster. Example:
Missing HEIGHT and WIDTH attributes in an IMG tag.
· "FLUFF"
Fluff is for items that don't hurt your page, but don't help it
either. This is usually something like an unknown attribute on a
tag.
new()
Create an object. It's not very exciting.
is_type( $type1 [, $type2 ] )
Tells if any of $type1, $type2... match the error's type. Returns the
type that matched.
if ( $err->is_type( HTML::Lint::Error::STRUCTURE ) ) {....
where()
Returns a formatted string that describes where in the file the error
has occurred.
For example,
(14:23)
for line 14, column 23.
The terrible thing about this function is that it's both a plain ol'
formatting function as in
my $str = where( 14, 23 );
AND it's an object method, as in:
my $str = $error->where();
I don't know what I was thinking when I set it up this way, but it's
bad practice.
as_string()
Returns a nicely-formatted string for printing out to stdout or some
similar user thing.
file()
Returns the filename of the error, as set by the caller.
line()
Returns the line number of the error.
column()
Returns the column number, starting from 0
errcode()
Returns the HTML::Lint error code. Don't rely on this, because it will
probably go away.
errtext()
Descriptive text of the error
type()
Type of the error
POSSIBLE ERRORS
Each possible error in HTML::Lint has a code. These codes are used to
identify each error for when you need to turn off error checking for a
specific error.
config-unknown-directive
Unknown directive "DIRECTIVE"
You specified a directive in a comment for HTML::Lint that it didn't
recognize.
config-unknown-value
Unknown value "VALUE" for DIRECTIVE directive
Directive values can only be "on", "off", "yes", "no", "true", "false",
"0" and "1".
elem-unknown
Unknown element <TAG>
HTML::Lint doesn't know what a TAG tag is. These are pulled from
HTML::Entities
elem-unopened
</TAG> with no opening <TAG>
elem-unclosed
<TAG> at WHERE is never closed
elem-empty-but-closed
<TAG> is not a container -- </TAG> is not allowed
elem-img-alt-missing
<img src="FILENAME.PNG"> does not have ALT text defined
elem-img-sizes-missing
<img src="FILENAME.PNG"> tag has no HEIGHT and WIDTH attributes
elem-nonrepeatable
<TAG> is not repeatable, but already appeared at WHERE
doc-tag-required
<TAG> tag is required
attr-repeated
ATTR attribute in <TAG> is repeated
attr-unknown
Unknown attribute "ATTR" for tag <TAG>
text-invalid-entity
