Great work! .zip and .rar support, please! 

[Ai4rei 321]

Both formats will need some work.

 

Originally I thought, RAR might be easier, but turns out, unrar expects a physical file, rather than an arbitrary data stream (patches are only offloaded to disk, if the OS deems that necessary). There are also few the problems with RAR6, but should be fixable in a way or another.

 

ZIP should be relatively easy.

 

There won't be support for password-protection and encryption.

this same like thor patcher?
can unpack thor file?

[Ai4rei 321]

Yes, this belongs to the same group of software as Thor Patcher.

If there will be interest for that, there can be support for THOR files, too. Currently it can only work with GPF and RGZ.

It would be great if it could support THOR files and encrypted grf so we could use this instead of Thor Patcher, without those, this patcher would only work for official data and official servers

Edited January 13, 2022 by MrSky

[Ai4rei 321]

Elurair already supports updating encrypted GRFs/GPFs (such as SecureGRF).

 

Normally there is no added benefit to using Thor files other than compatibility with previous patcher, since Thor files are not encrypted as far as I know.

 

2022-01-22:

- ZIP support complete

- RAR is held until I'm bored enough to enter that source code abyss and figure out, how to make it open something other than files

You can patch any file. Put it into a RGZ, ZIP or 7Z archive and patch that.
