use Compiler::Lexer;
use Compiler::Parser;
use Compiler::Parser::AST::Renderer;
my $filename = $ARGV[0];
open(my $fh, "<", $filename) or die("Cannot open $filename: $!");
my $script = do { local $/; <$fh> };
my $lexer  = Compiler::Lexer->new($filename);

Compiler::Parser creates abstract syntax tree for perl5.

• my $parser = Compiler::Parser->new();

    Create new instance of Compiler::Parser.
  

• my $ast = $parser->parse($tokens);

    Get blessed object of Compiler::Parser::AST.
    This method requires $tokens from Compiler::Lexer::tokenize.
  

• my $renderer = Compiler::Parser::AST::Renderer->new();

    Create new instance of Compiler::Parser::AST::Renderer.
  

• $renderer->render($ast)

    Render abstract syntax tree.
    This method requires $ast from Compiler::Parser::parse.
    Default rendering engine is Compiler::Parser::AST::Renderer::Engine::Text.
