HTML::Lint::Error(3p)

NAME
HTML::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.

  api-parse-not-called
You called the "errors()" method before calling "parse()" and "eof()".

  api-eof-not-called
You called the "errors()" method before calling "eof()".

  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
HTML::Lint doesn't know recognize the tag.

  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-unclosed-entity
Entity ENTITY is missing its closing semicolon

  text-unknown-entity
Entity ENTITY is unknown

  text-use-entity
Character "CHAR" should be written as ENTITY
