Installation

Themer works with Rails 5 onwards. You can add it to your Gemfile with:

gem 'themer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install themer

If you always want to be up to date fetch the latest from GitHub in your Gemfile:

gem 'themer', github: 'jonhue/themer'

Now run the generator:

$ rails g themer

Usage

To setup Themer, use the themify_class helper method to specify the current theme in your views html tag:

<html class="<%= themify_class %>">

Then create a current_theme helper method in your ApplicationHelper (app/helpers/application_helper.rb):

def current_theme
    themer current_user.theme
end

Note: This helper method is not required but helpful when you want to store information about selected themes in your database.

Lastly, add the following to your application.sass file (app/assets/stylesheets/application.sass):

@import "themer/default"
@import "themer"

Stylesheets

To get started define your colors in the 'default' theme (app/assets/stylesheets/themer/default.sass):

$themer--default: (
    text: (
        dark: #000000,
        base: #eeeeee
    ),
    background: #ffffff
);

In your Sass stylesheets you are able to use the color function to access your theme colors:

html
    background: color(background)
p
    color: color(text, base)

Note: If you need to get a HEX value for a specific color pass true as a third parameter to the color function. This will return the color for the theme set as default.

Methods

Themer adds a couple of helpful methods to your controllers and views:

# Returns the currently used theme. Passed parameter overrides theme stored in cookies and default theme.
themer current_user.theme

# Set the theme
set_themer 'default'

# Check if a theme is available
themer_available? 'default'

# Return Themer class for `html` tag
themer_class

Switching themes automatically

You can configure Themer to update the theme based on day and nighttime.

To automatically select a theme just set the theme to 'auto':

set_themer 'auto'

Configuration

You can configure Themer by passing a block to configure. This can be done in config/initializers/themer.rb:

Themer.configure do |config|
    config.themes = ['default']
end

themes Array of available themes. Takes an array of strings. Defaults to ['default'].
default Default theme. Takes a string. Defaults to 'default'.
auto Enable automatic themes. Takes a boolean. Defaults to false.
day Day theme. Takes a string. Defaults to 'light'.
night Night theme. Takes a string. Defaults to 'dark'.
day_time Beginning of daytime. Takes a string. Defaults to '6:00 am'.
night_time Beginning of nighttime. Takes a string. Defaults to '6:00 pm'.
