Name

SPVM::Native::Compiler - Native::Compiler

Description

SPVM::Native::Compiler is the Native::Compiler class in the SPVM language. It compiles SPVM source codes and builds the runtime.

The instance of the Native::Runtime class is build by the "get_runtime" method in this class.

Usage

use Native::Compiler;

my $compiler = Native::Compiler->new;

$compiler->add_include_dir("lib");

$compiler->set_start_file(__FILE__);

{
  my $basic_type_name = "Foo";
  $compiler->set_start_line(__LINE__ + 1);
  $compiler->compile($basic_type_name);
}

{
  my $basic_type_name = "Bar";
  $compiler->set_start_line(__LINE__ + 1);
  $compiler->compile($basic_type_name);
}

my $runtime = $compiler->get_runtime;

Pointer

The Native::Compiler class is a pointer class.

Its insntace has a pointer to a compiler object.

Class Methods

new

static method new : Native::Compiler ();

Creates a new Native::Compiler object and returns it.

Instance Methods

add_include_dir

method add_include_dir : void ($include_dir : string);

Adds a class directory to search for classes.

set_start_file

method set_start_file : void ($start_file : string);

Sets the name of the file to start the compiling by the "compile" method.

set_start_line

method set_start_line : void ($start_line : int);

Sets the line to start compiling by the "compile" method.

compile

method compile : void ($basic_type_name : string);

Compiles the specified class and the classes that are load in the specified class.

This method can be called multiple times.

Exceptions:

If compilation errors occurred, an exception is thrown set eval_errro_id to the basic type ID of the Error::Compile class.

get_error_messages

method get_error_messages : string[] ();

Returns compilation error messages in this compiling by the "compile" method.

get_runtime

method get_runtime : Native::Runtime ();

Returns the runtime.

The return value is a Native::Runtime object.

get_class_file

method get_class_file : Native::ClassFile ($class_name : string);

Gets a Native::ClassFile object by a class name, and returns it.

compile_anon_class

native method compile_anon_class : string ($source : string);

Compiles a anon class, and return the generated anon class name.

This method can be called multiple times. Exceptions:

If compilation errors occurred, an exception is thrown set eval_errro_id to the basic type ID of the Error::Compile class.

Examples:

use Native;
use Native::Compiler;
use Native::MethodCall;

my $compiler = Native->get_current_compiler;

my $source = <<'EOS';
class {
static method sum : int ($num1 : int, $num2 : int) {
  return $num1 + $num2;
}
}
EOS
$compiler->set_start_file(__FILE__);
$compiler->set_start_line(__LINE__ + 1);
my $anon_class_name = $compiler->compile_anon_class($source);;

my $ret = Native::MethodCall->call_class_method($anon_class_name, "sum", [(object)1, 2]);;

say $ret->(Int)->value;
