PKGUPD is a better package manager and successor of appctl in rlxos, PKGUPD aims to be a modular/extensible package manager whose functionality can be increase using the modules

Working

PKGUPD uses YAML configuration files named recipe file that contains a minimal set of information about the specific package or sub-packages. As per the information, PKGUPD performs the tasks and calls the specified modules.

PKGUPD support 2 types of extensions:

  • pack: This plugin provides a method to pack and unpack the binary packages that PKGUPD use to perform installations and package generation.
  • plugin: (I know bad naming) This provided methods to compile the source codes.

PKGUPD currently provided 4 plugins:

  • auto: Compilation plugin that can detect autogen.sh, configure, Makefile, CMakeLists.txt, meson.build and python setup.py
  • port: Another compilation plugin that uses appctl port (like PKGBUILD files in arch linux).
  • rlx: Packaging plugin that pack the binary packages in rlxos package format
  • app: Another packaging plugin for AppImages format.
