better command support?

[chino]

It would be nice to simply eval whatever is left on the command line.

For instance I'd love to do:

rbenv each -v gem list \| grep "a b"

With proper quoting support so that the grep in the example above works appropriately.

No, we're not going to do anything tricky like that. If you find yourself needing to do some shell functions/piping across rbenv versions, you could simply:

for v in `rbenv versions --bare`; do RBENV_VERSION=$v gem list | grep "a b"; done

[chino]

Yea, I just basically took that and change it to call eval "$@" and it seems to work great...

Would be cool if rbenv-each supported it.

I want to refrain from doing eval internally since that is not how I want people to use rbenv-each.

However you can always execute bash interpreter with any script that you want:

rbenv each bash -c 'gem list | grep "a b"'

Hm, your right. I forget off top of my head and I'm on road right now but does rbenv support aliases? It could be a simple handy alias.

rbenv doesn't support aliases but your shell does ;)

alias rbenv-each-eval='rbenv each bash -c'

[chino]

I agree. However I do like git aliases even though they could just be shell aliases :)
