NAME

SPVM - Fast calculation, GC, static typing, VM with perlish syntax

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

SYNOPSIS

  use FindBin;
  use lib "$FindBin::Bin/lib";

  use SPVM 'MyModule2';

  my $total = SPVM::MyModule2::foo(3, 5);
  print $total . "\n";

Module file

  # lib/SPVM/MyModule1.spvm
  package MyModule1 {
    has x : int;
    has y : int;

    sub sum ($x : int, $y : int) : int {

      my $total = $x + $y;

      return $total;
    }
  }

  # lib/SPVM/MyModule2.spvm
  use MyModule1;
  package MyModule2 {

    sub foo ($x : int, $y : int) : int {

      my $total = ($x * $y) + MyModule1::sum(2, 4);

      return $total;
    }
  }

If you want to know more syntax, see solo/SPVM/Test.spvm.

If you want to know SPVM language, see solo/README.md

DESCRIPTION

Do you need faster Perl? SPVM provides fast calculation 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.

SPVM Tutorial

SPVM is a language which is similar with Perl. SPVM is very similar to Perl, and you can write same syntax of Perl in most part.

SPVM communicate with Perl. You can call SPVM function directory from Perl.

SPVM is very fast and provide array data structure. Now SPVM array operation is about 6x faster.

SPVM module

At first, you can write SPVM module.

  # lib/SPVM/MyModule1.spvm
  package MyModule1 {
    has x : int;
    has y : int;

    sub sum ($x : int, $y : int) : int {

      my $total = $x + $y;

      return $total;
    }
  }

This is same as Perl except SPVM have static type and has keyword.

You can define field by has keyword, and specify static type by : type.

  has x : int;

You can specify argument types and return type to subroutine by : type.

  sub sum ($x : int, $y : int) : int {

    my $total = $x + $y;

    return $total;
  }

Let's save this file by the following name

  lib/SPVM/MyModule1.spvm

If package name is MyModule1, file name must be SPVM/MyModule1.spvm.

Extension is spvm. And you create SPVM directory.

lib is normal directory.

Call SPVM subroutine

Next you can use SPVM subroutine from Perl.

  use FindBin;
  use lib "$FindBin::Bin/lib";

  use SPVM 'MyModule1';

  my $total = SPVM::MyModule1::sum(3, 5);
  print $total . "\n";

At first, you add library path by FindBin and lib module.

  use FindBin;
  use lib "$FindBin::Bin/lib";

Next, use SPVM module. MyModule1 is loaded.

  use SPVM 'MyModule1';

And call SPVM subroutine. If SPVM subroutine absolute name is MyModule1::sum, you can call this subroutine by SPVM::MyModule1::sum.

  my $total = SPVM::MyModule1::sum(3, 5);
  print $total . "\n";
