Aliases for rbenv Ruby versions


rbenv alias  
to make a symbolic link from
 in the rbenv versions directory, effectively creating an
alias.  The cool part is that if you pass in a point release as the name, you
can give 
to link to the latest installed patch level. For example,
rbenv alias 1.8.7 --auto
will automatically create an alias from
(or whatever the most recent version you have installed is).

Plus, if you're using ruby-build,

rbenv install A.B.C-pXXX
automatically invokes
rbenv alias A.B.C --auto
, so you'll always have up to date aliases for point releases.

Whether it's a good idea to use these aliases in a

file, I cannot say. I created this plugin to find out. If your only concern is having to reinstall gems every time you install a new patch release, check out rbenv-communal-gems.

rbenv alias --auto
