.SH "NAME"
Text::MicroMason::PLP \- Alternate Syntax like PLP Templates
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Instead of using this class directly, pass its name to be mixed in:
.PP
.Vb 2
\&    use Text::MicroMason;
\&    my $mason = Text::MicroMason::Base\->new( \-PLP );
.Ve
.PP
Use the standard compile and execute methods to parse and evaluate templates:
.PP
.Vb 2
\&  print $mason\->compile( text=>$template )\->( @%args );
\&  print $mason\->execute( text=>$template, @args );
.Ve
.PP
The \s-1PLP\s0 syntax provides another way to mix Perl into a text template:
.PP
.Vb 9
\&    <: my $name = $ARGS{name};
\&      if ( $name eq \*(AqDave\*(Aq ) {  :>
\&      I\*(Aqm sorry <:= $name :>, I\*(Aqm afraid I can\*(Aqt do that right now.
\&    <: } else { 
\&        my $hour = (localtime)[2];
\&        my $daypart = ( $hour > 11 ) ? \*(Aqafternoon\*(Aq : \*(Aqmorning\*(Aq; 
\&      :>
\&      Good <:= $daypart :>, <:= $name :>!
\&    <: } :>

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This subclass replaces MicroMason's normal lexer with one that supports a syntax similar to that provided by the \s-1PLP\s0 module.
.SS "Compatibility with \s-1PLP\s0"
.IX Subsection "Compatibility with PLP"
\&\s-1PLP\s0 is a web-oriented system with many fatures, of which only the templating functionality is emulated.
.PP
This is not a drop-in replacement for \s-1PLP,\s0 as the implementation is quite different, but it should be able to process some existing templates without major changes.
.PP
The following features of EmbPerl syntax are supported:
.IP "\(bu" 4
Basic markup tags
.PP
The following syntax features of are \fBnot\fR supported:
.IP "\(bu" 4
Emulation of functions defined in PLP::Functions is incomplete.
.IP "\(bu" 4
Web server interface with tied
.SS "Template Syntax"
.IX Subsection "Template Syntax"
The following elements are recognized by the \s-1PLP\s0 lexer:
.IP "\(bu" 4
<: perl statements :>
.Sp
Arbitrary Perl code to be executed at this point in the template.
.IP "\(bu" 4
<:= perl expression :>
.Sp
A Perl expression to be evaluated and included in the output.
.IP "\(bu" 4
<( file, arguments )>
.Sp
Includes an external template file.
.SS "Private Methods"
.IX Subsection "Private Methods"
.IP "lex_token" 4
.IX Item "lex_token"
.Vb 1
\&  ( $type, $value ) = $mason\->lex_token();
.Ve
.Sp
Lexer for <: ... :> and <( ... )> tags.
.Sp
Attempts to parse a token from the template text stored in the global \f(CW$_\fR and returns a token type and value. Returns an empty list if unable to parse further due to an error.
.IP "assemble" 4
.IX Item "assemble"
Performs compile-time file includes for any include tokens found by lex_token.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
The interface being emulated is described in \s-1PLP\s0.
