I introduce Easy C/C++ Binding using SPVM . In Perl, C/C++ binding is very very hard work. If you use SPVM, the work become very easy.

If You don't yet know SPVM itself, See SPVM Document at first.

SPVM Module:

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

C Source File:

I start to write SPVM Language Specification.

SPVM Language Specification(Beta before 1.0)

SPVM array operation is 6x faster than Perl 5.26 now. If JIT is implemented, array operation maybe 20x faster than Perl 5.26. This is planed in one year.

SPVM provide you,

-You can write Fast culculation without XS
-You can bind C library without XS
-You can write C language inline without Inline::C

XS is very complex and difficu…
