More work towards making Homebrew/brew a cross-platform core for e.g. Linuxbrew and Tigerbrew too.

I know the benefits outweigh the costs here, but all this refactoring for cross-platform compatibility makes it a complete nightmare to quickly gather a full picture in terms of what calling require on x actually drags in. On the record, I'll buy anyone who invents an Atom plugin to automatically follow requires a 🍺 or five.

Can you explain what this was/is supposed to do? I don't really understand this, but I'm not sure the replacement is equivalent.

Set ENV.x11 if MacOS::X11.installed?

[UniqMartin]

I find this massively confusing, also when compared to what x11 means in stdenv. But oh well, I guess legacy …

[MikeMcQuaid]

Open to better suggestions. Have a generic_sh method?

[UniqMartin]

I'm not sure. I never used brew sh and I'm not entirely sure what that line is supposed to do (in more broader terms, I understood your explanation from above).

You might want to give brew graph-require (a quick and undocumented late-night hack, including code comments that just stop mid-sentence as I just noticed 😂) a try, e.g.:

brew graph-require --start=extend/ENV/super | dot -Tpdf > super.pdf
open super.pdf

Graph for extend/ENV/super. Solid lines represent plain requires, dashed lines typically conditional requires. The heuristics for that are really simple, thus better check if in doubt.

This would involve touching JavaScript, something I'm not considering just yet. :eek:
