RGSS Archive Data #6

Closed qnighy closed 6 years ago

qnighy commented 6 years ago

Load data from archives like Game.rgssad, Game.rgss2a, Game.rgss3a.

Implementation strategy:

[x] Implement a skeleton that issues "no decryption module" error.
[x] Implement a decryption module in a private repo.
[ ] Prepare an infrastructure to provide a build with the decryption module.

Related to #23 : there is actually a concern about LGPL infection.

Problem: Ruby 1.8.1 contains regex.c from GNU, which is LGPL-licensed. Therefore (I think) we can't distribute binaries without sources.

Question: how does the original RGSS resolve this licensing issue? Or, does it?

qnighy commented 6 years ago

Easy approach: compile regex.c alone as a shared library or compile Ruby 1.8.1 alone as a shared library. However, current tapir nor RGSS doesn't seem to do it. Looks statically linked.

I've decided to just include archive module in the public source code. This implies people can look into the source to know how encryption works. However, I suspect they would search for "decryption tools" in the wild instead of reading my complicated (sorry!) source code.

Closing in favor of a69b4c2.
