resolvedeps.sh
A standalone script for dependency resolution.
This is in alpha/toy/experiment state. Not ready for production, as they say.
A standalone script that can resolves deps of a given package name is something I wanted years ago, cos:
- The dep resolution functions in PPM are hard to extract.
- The dep resolution function in Pkg is not very good.
This resolvedeps.sh can only do package "short names" or "bare names" (no versions, name only, so gimp, mplayer, etc).
Usage
Code: Select all
source resolvedeps.sh
resolvedeps gimp
resolvedeps krita
resolvedeps kodiFeatures:
- accepts package short name, returns its list of deps (recursive)
- searches all repos at once
- mostly faster than PPM and Pkg
- hides builtin packages
- hides devx packages
- hides blacklisted packages (it reads from the file ~/.pkg/blacklisted_packages)
- that's it
Issues & bugs I'd like to fix:
- does not respect minimum/maximum version numbers in package filenames (it simply strips off the
&ge1.2.0,<4.0etc) - does not respect "epochs" in package filenames (strips them off too)
- does not check for correct architecture (x86_64, arm, etc)
- does not know about "multilib" anything (cos nor do I)
- does not respect package "alias" name (like PPM and Pkg do)
- does not respect your repos fallback order (as defined in Pkg configs)
- does not respect your chosen list of "supported" repos (it will search all available repo files, no matter what)
- does not hide user installed packages (this may be desired, maybe not)
- only tested on Focal Fossa, should work in all pups that support PET packages
