Optimal place to print post-install message

I am updating a PKGBUILD which I also plan to add a message about a recommended configuration (namely, using system python instead of integrated). Is the best way really to bundle a whole .install script just to put an echo inside the post_install() function? Or should I put the echo inside package()?

Re: Optimal place to print post-install message

If you want the message to be echoed after a package is installed, that's precisely what post_install is for.  If you put an echo command in package(), it will - as the name of the function implies - only print out when the software is packaged ... not when built packages are installed.

Facetiousness aside: this question only comes from an assumption that others will build/install in one fell swoop (i.e., use makepkg -i).  That is neither a safe assumption, or one that should be made in writing PKGBUILDs.

Re: Optimal place to print post-install message

Do I need to package in a separate .install file just for the post_install function?

Yes.  This file is bundled with the package itself and will be sourced by pacman later.  It is not sourced by makepkg.

Ah, that makes a lot of sense. Thanks.
