NAME

       "LaTeXML::Mouth" - tokenize the input.

DESCRIPTION

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

       "LaTeXML::FileMouth"
	   specializes "LaTeXML::Mouth" to tokenize from a file.

       "LaTeXML::StyleMouth"
	   further specializes "LaTeXML::FileMouth" for processing style files, setting the catcode for "@" and ignoring comments.

       "LaTeXML::PerlMouth"
	   is not really a Mouth in the above sense, but is used to definitions from perl modules with exensions ".ltxml" and ".latexml".

   Creating Mouths
       "$mouth = LaTeXML::Mouth->new($string);"
	   Creates a new Mouth reading from $string.

       "$mouth = LaTeXML::FileMouth->new($pathname);"
	   Creates a new FileMouth to read from the given file.

       "$mouth = LaTeXML::StyleMouth->new($pathname);"
	   Creates a new StyleMouth to read from the given style file.

   Methods
       "$token = $mouth->readToken;"
	   Returns the next LaTeXML::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 = $mouth->readRawLines($endline,$exact);"
	   Reads raw (untokenized) lines from $mouth until a line matching $endline is found.  If $exact is true, $endline is matched exactly,
	   with no leading or trailing data (like in the c<comment> package).  Otherwise, the match is done like with the c<verbatim> environment;
	   any text preceding $endline is returned as the last line, and any characters after $endline remains in the mouth to be tokenized.
