SPVM - The SPVM Language

Description

SPVM is a statically typed programming language that has Perl-like syntax.

SPVM has not yet reached a stable release of version 1.0. For now, there is currently no policy to keep the backward compatibility.

Usage

One Liner

Run a one liner using spvm command.

# Hello World!
spvm -e 'say "Hello World!";';

Run a one liner with loading a class.

# foo,bar,baz
spvm -M Fn -e 'say Fn->join(",", ["foo", "bar", "baz"]);'

Executing An SPVM Program

Write a SPVM class to print "Hello World!" using the say operator.

# lib/SPVM/HelloWorld.spvm
class HelloWorld {
  static method main : void () {
    
    say "Hello World!";
  }
}

Run the SPVM program using spvm command.

spvm -I lib/SPVM HelloWorld

Generating An Executable File

Generate an executable file using spvmcc command.

spvmcc -B ~/.spvm_build -o ./hello --no-config -I lib/SPVM HelloWorld

Run the executable file.

./hello

Calling An SPVM Method from Perl

Write an SPVM class.

# 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;
  }
}

Write a Perl program calling an SPVM method using exchange APIs.

# sum.pl
use FindBin;
use lib "$FindBin::Bin/lib";

use SPVM 'MyMath';

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

print "$total\n";

Run the Perl program.

# Run
perl sum.pl
