NAME

SPVM - Static Perl Virtual Machine. Fast calcuration & Easy C/C++ Binding

SYNOPSIS

SPVM Module:

  # lib/MyMath.spvm
  package MyMath {
    sub sum : int ($nums : int[]) {
      
      my $total = 0;
      for (my $i = 0; $i < @$nums; $i++) {
        $total += $nums->[$i];
      }
      
      return $total;
    }
  }

Use SPVM Module from Perl

  use FindBin;
  use lib "$FindBin::Bin/lib";
  
  use SPVM 'MyMath';
  
  # New int array
  my $sp_nums = SPVM::new_int_array([3, 6, 8, 9]);
  
  # Call subroutine
  my $total = MyMath->sum($sp_nums);
  
  print $total . "\n";

DESCRIPTION

SPVM is Static Perl Virtual Machine. Provide fast calcuration & easy C/C++ Binding.

Features:

• Fast culcuration, Fast array operation, Small memory

• Perl syntax, Static typing, Switch syntax, Have language specification

• Enum, Type inference, Anon subroutine, Variable captures

• Array initialization,

• Reference count GC, Weaken reference, Module system

• Exception, Package variable

• Object oriented, Inteface, Value type, Value array type, Reference type

• Easy way to C/C++ binding, Automatically Perl binding, C99 math functions

• Dynamic linking, Subroutine precompile, AOT compile(create exe file)

• Native API(C level api), C99 standard

EXAMPLES

How to use SPVM from Perl

SPVM Module:

  # lib/MyMath.spvm
  package MyMath {
    sub sum : int ($nums : int[]) {
      
      my $total = 0;
      for (my $i = 0; $i < @$nums; $i++) {
        $total += $nums->[$i];
      }
      
      return $total;
    }
  }

Use SPVM Module from Perl

  use FindBin;
  use lib "$FindBin::Bin/lib";
  
  use SPVM 'MyMath';
  
  # New int array
  my $sp_nums = SPVM::new_int_array([3, 6, 8, 9]);
  
  # Call subroutine
  my $total = MyMath->sum($sp_nums);
  
  print $total . "\n";

C Extension using SPVM

SPVM Module:

  # lib/MyMathNative.spvm
  package MyMathNative {
    
    # Sub Declaration
    native sub sum int ($nums : int[]);
  }

C Source File;

  // lib/MyMathNative.native/MyMathNative.c
  #include <spvm_native.h>

  int32_t SPVM_NATIVE_MyMathNative__sum(SPVM_ENV* env, SPVM_VALUE* stack) {
    
    // First argument
    void* sp_nums = stack[0].oval;
    
    // Array length
    int32_t length = env->get_array_length(env, sp_nums);
    
    // Elements pointer
    int32_t* nums = env->get_int_array_elements(env, sp_nums);
    
    // Culcurate total
    int32_t total = 0;
    {
      int32_t i;
      for (i = 0; i < length; i++) {
        total += nums[i];
      }
    }
    
    // Return value is set to stack[0]
    stack[0].ival = total;
    
    // If function success, return SPVM_SUCCESS
    return SPVM_SUCCESS;
  }

Use Extension Module from Perl:

  use FindBin;
  use lib "$FindBin::Bin/lib";
  
  # Use SPVM module
  use SPVM 'MyMathNative';
  
  # New SPVM int array
  my $sp_nums = SPVM::new_int_array([3, 6, 8, 9]);
  
  # Call SPVM subroutine
  my $total = MyMathNative->sum($sp_nums);
  
  print $total . "\n";
