SPVM - Fast Calculation and Easy C/C++ Binding with perlish syntax and static typing

SPVM is before 1.0 under development! I will change implementation and specification without warnings.


Fast Array Operation using SPVM.

SPVM Module:

  # lib/SPVM/MyMath.spvm
  package MyMath {
    # Sub Declaration
    sub sum ($nums : int[]) : int {
      # Culcurate total
      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 module
  use SPVM 'MyMath';
  # New SPVM int array
  my $sp_nums = SPVM::new_int_array([3, 6, 8, 9]);
  # Call SPVM subroutine
  my $total = SPVM::MyMath::sum($sp_nums);
  print $total . "\n";

If you know more SPVM syntax, see SPVM::Document::Specification.

If you know more Functions to convert Perl Data to SPVM Data, see SPVM::Document::Functions.

C Extension using SPVM

SPVM Module:

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

C Source File;

  // lib/SPVM/MyMathNative.native/MyMathNative.c
  #include <spvm_api.h>

  int32_t SPVM__MyMathNative__sum(SPVM_API* api, SPVM_API_VALUE* args) {
    // First argument
    SPVM_API_OBJECT* sp_nums = args[0].object_value;
    // Array length
    int32_t length = api->get_array_length(api, sp_nums);
    // Elements pointer
    int32_t* nums = api->get_int_array_elements(api, sp_nums);
    // Culcurate total
    int32_t total = 0;
      int32_t i;
      for (i = 0; i < length; i++) {
        total += nums[i];
    return total;

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 $total = SPVM::MyMathNative::sum($sp_nums);
  print $total . "\n";

If you know more SPVM Extension, see SPVM::Document::Extension.

If you know the APIs to manipulate SPVM data, see SPVM::Document::NativeAPI.


SPVM provide Fast Culcuration and Easy way to Bind C/C++ Language to Perl.

  • Fast calculation - The Perl's biggest weak point is the calculation performance. SPVM provides fast calculations.

  • GC - You don't need to care about freeing memory

  • Static typing - Static typing for performance

  • VM - Byte codes are generated so that you can run them on SPVM language

  • Perlish syntax - SPVM syntax is very similar to Perl

  • Perl module - SPVM function can be called from Perl itself.

If you learn more SPVM, see SPVM Documentation.
