NAME

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

CAUTHION

SPVM is not yet 1.0. Please note SPVM can change without warnings. There can be a lot of changes until I feel good enough.

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;
  }
}

Exchange API

SPVM Exchange API converts Perl data structures to SPVM data structures, and vice versa.

Native API

SPVM Native API is C API 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.

Generate SPVM Native Modules

spvmgenlib is the command to generate SPVM native modules.

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 ...".

bash:

In bash, you can set SPVM_BUILD_DIR to the following.

export SPVM_BUILD_DIR=~/.spvm_build

csh:

In csh, you can set SPVM_BUILD_DIR to the following.

setenv SPVM_BUILD_DIR ~/.spvm_build

SPVM_CC_DEBUG

Print SVPM::Builder::CC compile and link outputs to stderr.

SPVM_CC_FORCE

Force SVPM::Builder::CC compile and link.

CAUTION

This release is a beta release before SPVM 1.0. The features can change without notice. Use at your own risk.
