Gem and stubs


#1

what’s the deal? does it support them or not? the docs are confusing
on the
matter, but the latest certainly does not support them by default and
also no
longer accepts the --install-stubs option.

Library stubs have been unsupported for ages. In fact, when you
install RubyGems, it looks for any existing library stubs and removes
them :slight_smile:

When “require” gained the ability to look for libraries in installed
gems, library stubs were no longer needed or wanted.

Application stubs are a different matter. If a gem includes any
executables, they are proxied in your “bin” directory whether you like
it or not. AFAIK, there’s no option to control that.

yup. you are quite right. i missed that. they really should be there
as an
option though. otherwise this doesn’t work

irb -r postgres # postgres stub is installed

i liked that stubs were totally transparent to user code - they needed
do a
‘require “rubygems”’

oh well…

hmmm. thanks for the insight.

Yes, that’s the benefit, but it’s a shallow convenience, at the cost of
spewing crap in the filesystem.

Why not:

alias irb=“irb -r rubygems”

?

Or a special alias for a postgres-enabled irb if that’s something you
use often.
