loong64-it

Quickly converts "old-world" loongarch64 .deb packages to "new-world" loong64 ones - this is useful for distributions such as Debian and deepin who insists that architecture names should be different between worlds.

This aids users with libLoL-enabled loong64 distributions in installing and using old-world applications such as Tencent QQ and WPS for Linux.

Usage

loong64-it [PACKAGE1] [PACKAGE2] ...

	- PACKAGE{1..N}: Path to the old-world .deb package to convert.

Implementation

The script does the following:

• Examines the specified package file(s) as valid .deb package(s).
• Using ar, extracts control.tar* for processing.
  • Records the suffix and compression method of the control archive such that they could be replaced in-place in the original .deb.
• Examines and processes control, replacing the Architecture: field from loongarch64 to loong64, where applicable (returns an error if said package also comes with a loong64 (or anything other than the old/new- world pair) architecture key.
• Repacks the control.tar* archive and replaces it in-place.
• Instructs the user that the .deb file has been sucessfully processed and is ready to use (and recommends installing libLoL).
