E.2 LaTeXML::Core::Mouth

Tokenize the input.


A LaTeXML::Core::Mouth (and subclasses) is responsible for tokenizing, ie. converting plain text and strings into LaTeXML::Core::Tokens according to the current category codes (catcodes) stored in the LaTeXML::Core::State.

Creating Mouths

$mouth = LaTeXML::Core::Mouth->create($source, %options);

Creates a new Mouth of the appropriate class for reading from $source.

$mouth = LaTeXML::Core::Mouth->new($string, %options);

Creates a new Mouth reading from $string.


$token = $mouth->readToken;

Returns the next LaTeXML::Core::Token from the source.

$boole = $mouth->hasMoreInput;

Returns whether there is more data to read.

$string = $mouth->getLocator($long);

Return a description of current position in the source, for reporting errors.

$tokens = $mouth->readTokens($until);

Reads tokens until one matches $until (comparing the character, but not catcode). This is useful for the \verb command.

$lines = $mouth->readRawLine;

Reads a raw (untokenized) line from $mouth, or undef if none is found.
