Rubies
By default fry will look for rubies in ~/.rubies. This can be configured as you like.
Install (with ruby-install or ruby-build)
If you have ruby-install or
ruby-build installed, fry provides a wrapper
with auto-completion and building to the correct destination.
To install rubies this way, run the following command:
# To see available rubies
fry install
# To install a specific ruby version
fry install jruby-1.7.9
Configuration
To see which configuration options are available and your current configuration,
you can execute the command fry config.
Path (Rubies)
This option determines where fry looks for rubies.
# To see the path
fry config path
# To set the path
fry config path /opt/rubies
Prepend path
This option determines if your ruby path should be prepended or not. However it will never be at the end of your PATH since we are using fish_user_paths which is prepended to PATH. However if you have specified other paths inside your fish_user_paths then those will have higher priority. To change this behavior you can toggle this. The default behavior is append.
# To prepend to the fish_user_paths
fry config prepend on
# To append to the fish_user_paths
fry config prepend off
Auto-Switch
If you want fry to look for a .ruby-version file and
automatically switch ruby on directory change then you can enable auto-switching. This is off by default.
# To see the auto-switch status
fry config auto
# To enable auto-switch
fry config auto on
# To disable auto-switch
fry config auto off
Prax/Pow
If you are using prax or pow you can make it utilize the auto-switching capability.
When you have a .ruby-version file in your home directory this will be
used used by default. If you want it to pickup the custom ruby-version
per project you have to create a .praxconfig in your home directory or
for pow, you need to create a .powenv inside every project folder.
Run the following commands:
# If you have auto-switch, it will use whatever is specified in your .ruby-version
fry env > ~/.praxconfig
# Specify a specific ruby to run
fry env rbx-2.2.6 > ~/ruby_project/.praxenv
Installer
If you want to select which installer fry should use, you can do it
through this option. There are currently support for ruby-install and
ruby-build. But you could easily define your own wrapper if you use
some other tool.
# To list available installer wrappers
fry installers
# To see the installer used
fry config installer
# To set the desired installer
fry config installer ruby-install
Default Ruby
If you wish to set a default Ruby, simply call fry in ~/.config/fish/config.fish:
fry ruby-1.9
If you have enabled auto-switching, simply create a .ruby-version file in your home directory:
echo 'ruby-1.9' > ~/.ruby-version
