[pacman-dev] [PATCH v2] pacman+libalpm: print version names for conflicting packages
by morganamilo 11 Dec '19

11 Dec '19

When ever pacman prints a conflict, it now prints pkgname-version, instead of just pkgname. alpm_conflict_t now carries pointers to alpm_pkg_t instead of just the names of each package.
