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 ($class_name : string);
Compiles a class given by the class name $class_name.
This method can be called multiple times.
Exceptions:
If compilation errors occurred, an exception is thrown set eval_errro_id to the basic type ID of the Error::Compile class.
get_error_messages
method get_error_messages : string[] ();
Returns compilation error messages in this compiling by the "compile" method.
get_runtime
method get_runtime : Native::Runtime ();
Returns the runtime.
The return value is a Native::Runtime object.
get_class_file
method get_class_file : Native::ClassFile ($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 $ret->(Int)->value;
eval_string
method eval_string : string ($main_source : string);
This method emulates Perl's string eval.
This method creates the following source code.
"
class {
static method main : void () {
#line 1
$main_source
}
}
"
And calls "compile_anon_class" given this source code and gets the anon class name.
And calls call_class_method in the Native::MethodCall class.
Native::MethodCall->call_class_method($anon_class_name, "main");
Examples:
Compiler->eval_string("my $total = 1 + 2; say $total;");
