README.md
Ruby
Configures Ruby local gem installation, loads version managers, and defines aliases.
Local Gem Installation
When a Ruby version manager is not detected, local gems are installed in
~/.gem
; otherwise, they are installed according to the manager.
rbenv
An alternative RVM is to use rbenv, which allows for switching between multiple, isolated Ruby installations in the home directory.
While it is not as feature rich as RVM, it is not loaded into the shell and is not known to cause conflicts with shell scripts.
This will be loaded automatically if rbenv is installed to $RBENV_ROOT
,
~/.rbenv
, or if the rbenv
command is on the path.
rvm
An alternative to the above is to use The Ruby Version Manager (rvm), which allows for managing multiple, isolated Ruby installations and gem sets in the home directory.
Since RVM is loaded into the shell and is known to override shell commands, it may conflict with shell scripts.
Load this module as late as possible when using RVM since RVM will complain if
it is not first in $PATH
.
chruby
Yet another alternative is chruby, which is simpler than both rvm and rbenv.
Settings
Auto-Switch
To enable auto switching the Ruby version on directory change based on the
.ruby-version
file, add the following line to ${ZDOTDIR:-$HOME}/.zpreztorc
:
zstyle ':prezto:module:ruby:chruby' auto-switch 'yes'
Bundler
Manage gems that are not meant to be used as commands, such as application dependencies, with Bundler.
Aliases
General
rb
is short forruby
.
Bundler
rbb
manages ruby dependencies (bundle
).rbbc
cleans up unused gems in your bundler directory.rbbe
executes a script in the context of the current bundle.rbbi
installs the gems specified in theGemfile
invendor/bundle
.rbbI
installs the following:- gems specified in the
Gemfile
invendor/bundle
. - packages the gems into
vendor/cache
. - appends bundler directories to
.gitignore
.
- gems specified in the
rbbl
lists all gems in the current bundle.rbbo
opens an installed gem in the editor.rbbp
packages gem files intovendor/cache
.rbbu
updates gems to their latest version.
Functions
ruby-app-root
displays the path to the Ruby application root directory.ruby-info
exposes information about the Ruby environment via the$ruby_info
associative array.
Theming
To display the name of the current Ruby version in a prompt, define the
following style in the prompt_name_setup
function.
# %v - ruby version.
zstyle ':prezto:module:ruby:info:version' format 'version:%v'
Then add $ruby_info[version]
to $PROMPT
or $RPROMPT
and call
ruby-info
in the prompt_name_preexec
hook function.
