1. 1. Why we use mruby with Perl5? Kichijoji.pm #5 id:karupanerura
2. 2. Who am I? • id:karupanerura (twitter/github/hatena/etc..) • Perl/Swift/C/Java/JavaScript/etc… • Web/iOS/Android Engineer • Mobile Factory, Inc. • Lead Engineer
3. 3. mruby
4. 4. What is mruby? • Lightweight implementation of the Ruby language. • mRuby has a high compatibility with Ruby. • Used for embedded. • Binary size: 766.6[kb] (mruby-1.1.0)
5. 5. mRuby.pm
6. 6. What is mRuby.pm? • mruby binding for Perl5. • Using XS • tokuhirom++ • Embed mruby into Perl5. • We can call mruby code from Perl5 code.
7. 7. mRuby.pm • 0.07 - 2015-06-21 • upgrade mruby to version 1.1.0 • 0.08 - 2015-06-22 • Added high-level API. • Added `funcall` API.
8. 8. Example: low-level API use mRuby; my $mrb = mRuby::State->new(); my $st = $mrb->parse_string('1 + 2 + 3 + 4 + 5'); my $proc = $mrb->generate_code($st); my $ret = $mrb->run($proc); say $ret; # => 15
9. 9. Example: high-level API use mRuby; my $mruby = mRuby->new(src => '1 + 2 + 3 + 4 + 5'); my $ret = $mruby->run(); say $ret; # => 15
10. 10. Example: funcall API use mRuby; my $mruby = mRuby->new(src => q{ def add(l, r) l + r end }); my $ret = $mruby->funcall(add => 1, 2); say $ret; # => 3 my $ret2 = $mruby->funcall(add => 3, 4); say $ret2; # => 7
11. 11. We get mruby!
12. 12. But, why?
13. 13. Why we want to use mruby from Perl5?
14. 14. We are making a social game • Enviroment: • iOS - Swift • Android - Java • Web (API Server) - Perl
15. 15. We have MANY logics • Parameter calculate • Score calculate • Battle emulation • etc..
16. 16. We need to share business logics and configs in ALL ENVIROMENT.
17. 17. It’s too difficult…
18. 18. But, we gets mruby!
19. 19. BEFORE • iOS - Swift • Android - Java • Web (API Server) - Perl
20. 20. AFTER • iOS - Swift + mruby • Android - Java + (JNI+mruby) • Web (API Server) - Perl + (XS+mruby)
21. 21. CONCLUSION
22. 22. CONCLUSION • We can share codes and configs by mruby. • Perl & Swift & Java • Perl5 gets mruby!!
