Erb html templates uses Paul Battley's htmlbeautifier gem. This (as well as rubygems) is assumed to be installed as seen by the ruby interpreter. Note that if you beautify an erb file but htmlbeautifier is not found, the error message is 'check your ruby interpreter settings', do not be misled.

If an error is encountered while processing the file, Python receives an empty string and the following message is displayed but may have nothing to do with your Ruby settings.

check your ruby interpreter settings

This package offers a pre-save hook, i.e., your ruby and erb files will be reformatted automatically before saving. To activate this feature, set:

"run_on_save": true,

The sublime command "beautify_ruby" performs a save after formatting. You can disable this default by setting:

"save_on_beautify": false

You can change the file patterns handled by this plugin in the settings:

"file_patterns": [ "\\.html\\.erb", "\\.rb", "\\.rake", "Rakefile", "Gemfile" ],
"html_erb_patterns": ["\\.html\\.erb"],

This plugin uses ruby scripts to beautify your buffer, so it needs ruby installed. You can configure your ruby interpreter under Preferences -> Package Settings -> BeautifyRuby -> Settings Default/User click here for a screenshot. Although the default should work on linux and osx, not setting this right is a common problem.

If you do not use the system ruby, type in your favourite shell:

  which ruby

and place that in the ruby setting.

On windows, set Preferences -> Package Settings -> BeautifyRuby -> Settings Default

  "ruby": "ruby"

If you use project-specific rubies and gem sets managed with rvm, then simply set

  "ruby": "~/.rvm/bin/rvm-auto-ruby",

and then the htmlbeautifier gem is found even if it is only installed for this project.

If you are using ruby on the Windows Subsystem for Linux, use:

  "ruby": "wsl ruby"

By default, Sublime does not translate tabs to spaces. If you wish to use tabs you will not need to change your settings. If you wish to use spaces, add the following setting.

"translate_tabs_to_spaces": true

Or if you wish to force the use of tabs use:

"translate_tabs_to_spaces": false

Sublime's default tab_size is set to 4. Override this setting to change the number of spaces to use when using spaces instead of tabs.

"tab_size": 2

  ctrl + cmd + k on OS X, or ctrl + alt + k on Windows
