       Template::Parser - LALR(1) parser for compiling template documents


           use Template::Parser;

           $parser   = Template::Parser->new(\%config);
           $template = $parser->parse($text)
               || die $parser->error(), "\n";


       The "Template::Parser" module implements a LALR(1) parser and associated methods for
       parsing template documents into Perl code.


       The "new()" constructor creates and returns a reference to a new "Template::Parser"

       A reference to a hash may be supplied as a parameter to provide configuration values.  See
       "CONFIGURATION OPTIONS" below for a summary of these options and Template::Manual::Config
       for full details.

           my $parser = Template::Parser->new({
               START_TAG => quotemeta('<+'),
               END_TAG   => quotemeta('+>'),

       The "parse()" method parses the text passed in the first parameter and returns a reference
       to a hash array of data defining the compiled representation of the template text,
       suitable for passing to the Template::Document new() constructor method. On error, undef
       is returned.

           $data = $parser->parse($text)
               || die $parser->error();

       The $data hash reference returned contains a "BLOCK" item containing the compiled Perl
       code for the template, a "DEFBLOCKS" item containing a reference to a hash array of sub-
       template "BLOCK"s defined within in the template, and a "METADATA" item containing a
       reference to a hash array of metadata values defined in "META" tags.


       The "Template::Parser" module accepts the following configuration options.  Please see
       Template::Manual::Config for further details on each option.

       The START_TAG and END_TAG options are used to specify character sequences or regular
       expressions that mark the start and end of a template directive.

           my $parser = Template::Parser->new({
               START_TAG => quotemeta('<+'),
               END_TAG   => quotemeta('+>'),

       The TAG_STYLE option can be used to set both START_TAG and END_TAG according to pre-
       defined tag styles.

           my $parser = Template::Parser->new({
               TAG_STYLE => 'star',     # [* ... *]

       The PRE_CHOMP and POST_CHOMP can be set to remove any whitespace before or after a
       directive tag, respectively.

           my $parser = Template::Parser-E<gt>new({
               PRE_CHOMP  => 1,
               POST_CHOMP => 1,

       The INTERPOLATE flag can be set to allow variables to be embedded in plain text blocks.

           my $parser = Template::Parser->new({
               INTERPOLATE => 1,

       Variables should be prefixed by a "$" to identify them, using curly braces to explicitly
       scope the variable name where necessary.

           Hello ${name},

           The day today is ${}.

       The ANYCASE option can be set to allow directive keywords to be specified in any case.

           # with ANYCASE set to 1
           [% INCLUDE foobar %]    # OK
           [% include foobar %]    # OK
           [% include = 10   %]    # ERROR, 'include' is a reserved word

       The GRAMMAR configuration item can be used to specify an alternate grammar for the parser.
       This allows a modified or entirely new template language to be constructed and used by the
       Template Toolkit.

           use MyOrg::Template::Grammar;

           my $parser = Template::Parser->new({
               GRAMMAR = MyOrg::Template::Grammar->new();

       By default, an instance of the default Template::Grammar will be created and used
       automatically if a "GRAMMAR" item isn't specified.

       The DEBUG option can be used to enable various debugging features of the
       "Template::Parser" module.

           use Template::Constants qw( :debug );

           my $template = Template->new({
               DEBUG => DEBUG_PARSER | DEBUG_DIRS,
