Module depends on other module.

Say I want to make a scriptmodule to install, for example, a Doom mod (IWAD), that relies on an existing lr-prboom installation. How would I write the scriptmodule to check for and install or update if necessary, the other package? I see @fn hasPackage() but it looks like this only works for native Debian packages and not RP's own packages, right?

Would I just manually query the appropriate retropie.pkg in the PRboom install dir, or is there a slicker way?

Use rp_isInstalled to check if another scriptmodule is installed.

@mitu ah thanks, I knew I had seen an rp_something I was just looking in the wrong place (helpers).

And then if it's not installed, I'd do that with rp_installModule lr-prboom which is the same as rp_callModule lr-prboom _auto_ right?

Would this all go in the depends_ function of the other module?

And if I want to make sure it's the latest version anyway, could I just skip the check for rp_isInstalled and just do something like this?

function depends_mymod() {
    rp_callModule lr-prboom _autoupdate_
}

Yes.

Yes, you can add it there.

You could, but that would attempt to install/check update for lr-prboom each time instead of just checking locally that lr-prboom is installed.
