NAME
SPVM - Static Perl Virtual Machine. Fast calcuration & Easy C/C++ Binding
SYNOPSIS
package MyMath {
sub sum : int ($nums : int[]) {
my $total = 0;
for (my $i = 0; $i < @$nums; $i++) {
$total += $nums->[$i];
}
return $total;
}
}DESCRIPTION
SPVM provide fast array and numeric operation.
SPVM provide easy way to Bind C/C++ Language to Perl.
FEATURES
Fast array operation, Fast numeric operation, Static typing, Virtual machine, Precompile, Pre compile
Perlish syntax, Easy way to C/C++ binding, C99 math functions
EXAMPLES
How to use SPVM from Perl
SPVM Module:
# lib/MyMath.spvm
package MyMath {
sub sum : int ($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 $total . "\n";See also SPVM::Document::PerlAPI.
C Extension using SPVM
SPVM Module:
# lib/MyMathNative.spvm
package MyMathNative {
# Sub Declaration
native sub sum int ($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";See also SPVM::Document::Extension, SPVM::Document::NativeInterface.

NOTE
SPVM is before 1.0 under development! I will change implementation and specification without warnings.
Curent SPVM version is 0.3 serieses. This means implementation is finshed by 30% of version 1.0.
