Allow aliasing a file across conditional groups

[cultpony]

I'm currently trying to push some files into my Tuckr repository, getting them deployed on MacOS and Linux.

The problem being that the paths where the files need to end up are different, as they're system level;

MacOs' version stores it's global config as /Library/Application Support/AppName, the Linux variant uses /etc/appname.

While this is entirely solvable with a script or similar, I would love a way to alias files as that would spare me the effort of keeping the two in sync as I edit them.

Or maybe I missed how Tuckr does this.

There isn't an aliasing feature. The way I fixed this on my end was that different OSes have different standard paths where things typically go. So tuckr has some predefined env variables you can override that allow you to avoid duplication: https://raphgl.github.io/Tuckr/path-finding/env.html

These are only set for user directories right now, in the future I could add TUCKR_ROOT_CONFIG or whatever. Right now if you try to deploy dotfiles on paths in root that your current user does not have permissions for, you just won't be able to do it because I don't handle permission elevation at all. You would have to override the TUCKR_TARGET and TUCKR_HOME when running the program.

That I don't have permissions is fine, I just use sudo for that. The issue is that the spelling for the target directories is different; /etc/appname vs /Library/Application Support/AppName.

So I can't use the env expansion here, since they aren't just a prefix difference.

Yeah for that I think the symlink method would be appropriate (but I will have to change how validation works)
