Functions
|
||||
---------
|
||||
|
||||
- `ruby-info` exposes information about the Ruby environment via the
|
||||
`$ruby_info` associative array.
|
||||
|
||||
Theming
|
||||
-------
|
||||
|
||||
To display the name of the current Ruby version in a prompt, define the
|
||||
following style in the `prompt_theme_setup` function.
|
||||
|
||||
# %v - ruby version.
|
||||
zstyle ':prezto:module:ruby' version 'version:%v'
|
||||
|
||||
Then add `$ruby_info[version]` to `$PROMPT` or `$RPROMPT` and call
|
||||
`ruby-info` in the `prompt_theme_preexec` hook function.
