Use any HTML template as a theme generator for your Rails app.

Installs an HTML template, and its CSS, JavaScript and image assets into your Rails app, ready to go in an instant.

You just tell it which DOM elements are special, e.g. where to put the <%= yield %>, load your app in the browser and see the theme in action.

Simple case:

install_theme path/to/rails_app path/to/template content_path

Replace some DOM content with <%= yield :some_label %> with –partial:

install_theme path/to/rails_app path/to/template #content_box \
  --partial "header:#header h2 text()" \
  --partial sidebar:#sidebar"

NOTE: The order of the first two arguments has been reversed since the original public release. This is in preparation for path/to/template to be optional.

NOTE: The default behaviour of the css/xpath selectors has/is changing. Originally it replaced the internal content of the selected DOM node. Now, the default is to replace the entire DOM node. To replace the internal content of the DOM node use ‘/text()` (for xpath) or `:text` (for CSS paths) at the end of the selector.

For example, for CSS paths:

--partial ".header h2:text" # replaces contents of the h2 element
--partial ".header h2"        # replaces the h2 element itself

For Xpaths:

--partial "//div[@id='header']/h2/text()" # replaces contents of the h2 element
--partial "//div[@id='header']/h2"        # replaces the h2 element itself

The same goes for the content_path argument of the executable.

Similarly, in 0.7.0 the content_path argument is optional after the first time you install a specific theme (see ‘Theme Reuse’ section).

If your application has Haml installed, the template/theme is automatically converted to Haml, and the css files converted to Sass.

Alternately, you can pass the flag –haml to force it.

Or pass the flag –erb to force erb template generation.

Once you have installed a theme into an application once, that theme remembers the content path and partials you selected. You won’t have to type them again.

That is, after running the ‘install_theme` command above, you could apply the same theme to another Rails app using just:

install_theme path/to/app path/to/another_rails_app

The defaults for each theme are stored in a file ‘install_theme.yml`.

install_theme is distributed as a RubyGem, which installs the command line app automatically:

sudo gem install install_theme
install_theme -h
