NAME

SPVM - Static Perl Virtual Machine. Fast Calculation, Fast Array Operation, and Easy C/C++ Binding.

SYNOPSIS

SPVM Module:

  # lib/SPVM/MyMath.spvm
  class MyMath {
    static method sum : int ($nums : int[]) {

      my $total = 0;
      for (my $i = 0; $i < @$nums; $i++) {
        $total += $nums->[$i];
      }

      return $total;
    }
  }

Call SPVM method from Perl

  # spvm.pl
  use strict;
  use warnings;
  use FindBin;
  use lib "$FindBin::Bin/lib";

  use SPVM 'MyMath';

  # Call method
  my $total = SPVM::MyMath->sum([3, 6, 8, 9]);

  print "Total: $total\n";

  # Call method with packed data
  my $nums_packed = pack('l*', 3, 6, 8, 9);
  my $sv_nums = SPVM::new_int_array_from_bin($nums_packed);
  my $total_packed = SPVM::MyMath->sum($sv_nums);

  print "Total Packed: $total_packed\n";

Precompiled SPVM Method. This code is converted to C language and then converted to a shared library.

  # lib/SPVM/MyMath.spvm
  class MyMath : precompile {
    static method sum : int ($nums : int[]) {

      my $total = 0;
      for (my $i = 0; $i < @$nums; $i++) {
        $total += $nums->[$i];
      }

      return $total;
    }
  }

DESCRIPTION

SPVM is Static Perl Virtual Machine. SPVM is a programming language which has Perlish syntax. SPVM provides fast Calculation & easy C/C++ Binding.

FEATURES

  • Fast culcuration, Fast array operation

  • Precompile Method, Easy way to C/C++ binding, C99 math functions

  • Perlish syntax, Static typing, Type inference

  • Reference count GC, Weaken reference, Exception, Module

  • Object oriented programming

Exchagne API

SPVM Exchange API is APIs which convert Perl data structures to SPVM data structures, and the reverse.

Native API

SPVM Native APIs is C APIs used in SPVM native method.

Generate Execution File

spvmcc is a compiler to compile SPVM source codes to a execution file. The execution file can be run by itself.

ENVIRONMENT VARIABLE

SPVM_BUILD_DIR

SPVM build directory for precompile and native method.

If SPVM_BUILD_DIR environment variable is not set, SPVM can't compile precompile method and native method, and a exception occur. You see error message "SPVM_BUILD_DIR environment variable must be set ...".

In bash, you can set SPVM_BUILD_DIR to the following.

  export SPVM_BUILD_DIR=~/.spvm_build

CAUTION

This release is beta release before SPVM 1.0. The features is changed without warnings.
