[Bug]: install an alternative package #20941

Closed alexbodn closed 2 months ago

alexbodn commented 2 months ago

Problem description

i wish to create a package that is an alternative to another package, and provides the same functionality. the files in these packages conflict, naturally.

What steps will reproduce the bug?

i made a package b that "replaces" package a. it also breaks it and conflicts with it. trying to install package b, while a is installed, and d depends on a.

What is the expected behavior?

pkg install asks permission to uninstall a and d.

I think what you are asking is to break and replace a package at the same time. There's quite a lot of packages where that had to previously be done. Here's one example. https://github.com/termux/termux-packages/blob/697c89b4720b1b5bb32c1bfb549526b2f6d0853c/packages/util-linux/build.sh#L19-L20 You just need to set both TERMUX_PKG_BREAKS and TERMUX_PKG_REPLACES.

You should set TERMUX_PKG_CONFLICTS and TERMUX_PKG_PROVIDES, and also be better to set TERMUX_PKG_REPLACES.

Are those new, or did I just miss them?
