NAME

Text::MustacheTemplate::Compiler - Simple mustache template compiler

SYNOPSIS

use Text::MustacheTemplate::Lexer;
use Text::MustacheTemplate::Parser;
use Text::MustacheTemplate::Compiler;

# change delimiters
# local $Text::MustacheTemplate::Lexer::OPEN_DELIMITER = '<%';
# local $Text::MustacheTemplate::Lexer::CLOSE_DELIMITER = '%>';

my $source = '* {{variable}}';
my @tokens = Text::MustacheTemplate::Lexer->tokenize();

local $Text::MustacheTemplate::Parser::SOURCE = $source; # optional for syntax error reporting
my $ast = Text::MustacheTemplate::Parser->parse(@tokens);

my $template = Text::MustacheTemplate::Compiler->compile($ast);
my $result = $template->({ variable => 'foo' });
print "result: $result\n"; # print "* foo";

DESCRIPTION

Text::MustacheTemplate::Compiler is a compiler for Mustache template.

This is low-level interface for Text::MustacheTemplate. The APIs may be change without notice.

METHODS

compile($ast)

Compiles the abstract syntax tree (AST) from Text::MustacheTemplate::Parser into a Perl code reference (CodeRef) that renders the template when called.

Parameters:

$ast - The abstract syntax tree structure from the parser

Returns a CodeRef that takes a context scalar value and returns the rendered template string.

DESCRIPTION

Text::MustacheTemplate::Compiler takes the parsed AST and transforms it into executable Perl code that can efficiently render the template with a given context. This module handles the optimization of the compilation process and creates specialized code paths depending on the template structure.

The compiler performs several optimizations:

  • Direct interpolation of static text

  • Specialized handling for arrays, hashes, and lambda functions in section blocks

  • Optimized variable lookup with dot notation support

  • Proper handling of context stacking

INTERNALS

The compiler uses string eval to generate efficient Perl code that handles the template rendering. It creates a closure that has access to utility functions for HTML escaping, context resolution, etc.

The following internal optimizations are used:

  • Avoiding unnecessary concatenations for performance

  • Proper scope handling for nested sections

  • Special handling for lambda functions in templates

  • Context path resolution that follows Mustache specification
