[gentoo-user] What is a dependency of ruby

Hey Gentooers,

Not 100% back in the gentoo groove yet, forget some basic tools.

Something pulled in ruby, I know not what.

What commands show me what installed packages have ruby as a dependency?

I tend to use
# equery d dev-lang/ruby

equery from app-portage/gentoolkit

If at first you don't succeed, skydiving is not for you.

emerge --depclean --pretend ruby

No need to ask when you don't actually mean to depclean it... nor could
you if something depended on it.

Muscle memory added the --ask, but you do need verbose for this to give
the information you need.

emerge -cpv ruby

Why do you think so?  Trying to remove ruby will tell you why portage 
refuses to do so, and that reason is any installed packages that depend 
on it.  This differs from using equery, which will tell you every 
package that depends on ruby, whether or not it is installed.  Using -d 
instead of -a saves you from typing "N" just in case it IS willing to 
unmerge it.

Because I wanted to know, recursively, what packages depended on ruby, i.e.
I have ruby (which I despise) so why?

The answer is kdenlive which I can see in equery d, and cannot see in
emerge -c

This matters because emerge -avc only gives immediate dependencies, I
wanted to see the full dep tree

What options did you give to equery?
I had thought that "equery d" listed only direct dependencies, and that  
it listed packages whether installed or not.  Actually reading the fine  
equery man page, under the section on "depends (d)" are the options
-a, --all packages - Include dependencies that are not installed. This  
can take a while.
-D, --indirect - Search for both direct and indirect dependencies
so I was wrong on both counts.  I can imagine using -D might give a  
large list, but probably not so bad, as long as you don;t us both -a  
and -D.  Is this where you found kdenlive?
