Setup
$ gem install livingstyleguide -
Create sass/styleguide.lsg (replace
sass/with the directory name of your Sass files) with:// Replace with your default Sass/SCSS file name: @scss application.css.scss // Set the HTML title of the document: @title My Living Style Guide // Import all your style guide files @import sass/**/*.lsg -
Write documentation for each module sass/partials/_buttons.lsg (to describe _buttons.scss in the same folder):
# Buttons ``` <button class="button">Example button</button> ``` ``` <button class="button -primary">Example button</button> ``` -
Call
livingstyleguide compile sass/styleguide.lsg public/styleguide.htmlThis will automatically:- Combine all Markdown files and convert them to HTML
- Create a beautiful style guide
- Saves the style guide as public/styleguide.html
- Show the HTML source syntax highlighted close to each example
- Create your project with or without Compass.
- This can be easily integrated into non-Ruby build systems.
- If you omit the input and output filenames, STDIN and STDOUT will be used.
Be aware: From LSG v2 on Rails 3.x is not supported due to outdated Sprockets and Tilt versions.
-
Setup: Add this line to your application’s Gemfile:
gem "livingstyleguide"
And then execute:
$ bundle $ rails s -
Create app/assets/stylesheets/styleguide.html.lsg with:
// Replace with your default Sass/SCSS file name: @scss application.css.scss // Set the HTML title of the document: @title My Living Style Guide // Import all your style guide files @import **/*.lsg -
Write documentation for each module app/assets/stylesheets/partials/_buttons.lsg (to describe _buttons.sass in the same folder):
# Buttons ``` <button class="button">Example button</button> ``` ``` <button class="button -primary">Example button</button> ``` -
Open http://localhost:3000/assets/styleguide.html. This will automatically:
- Combine all Markdown files and convert them to HTML
- Create a beautiful style guide
- Show the HTML source syntax highlighted close to each example
-
Add the styleguide.html to the precompile list in config/application.rb:
config.assets.precompile += ["styleguide.html"]
-
There is a Rails example application available on Github.
-
Use sass-rails > v5 to allow Sass > v3.2:
# Gemfile: gem "sass-rails", "~> 5.0.0.beta1"
See issue #99 for discussions.
Since Rails 4 non-digest assets are not created anymore. If you want a public sharable url consider using something like Non Stupid Digest Assets
-
Setup: Add this line to your application’s Gemfile:
gem "livingstyleguide"And then execute:
$ bundle $ middleman -
Create source/styleguide.html.lsg with:
// Replace with your default Sass/SCSS file name: @scss application.css.scss // Set the HTML title of the document: @title My Living Style Guide // Import all your style guide files @import css/**/*.lsg -
Write documentation for each module source/css/partials/_buttons.lsg (to describe _buttons.sass in the same folder):
# Buttons ``` <button class="button">Example button</button> ``` ``` <button class="button -primary">Example button</button> ``` -
Open http://localhost:4567/styleguide.html. This will automatically:
- Combine all Markdown files and convert them to HTML
- Create a beautiful style guide
- Show the HTML source syntax highlighted close to each example
- Don’t put the styleguide.html.lsg into your CSS folder (
source/css/). It won’t work. - There is a Middleman example application available on Github.
- A more complex production project can be found online. The complete source of this Middleman project is available on Github. You’ll find a lot of configuration on how to make the style guide look beautiful.

Just write normal Markdown. The style guide examples are written in code blocks surrounded by three backticks:
```
<h1>This is an example</h1>
```
Just make sure, when you write a headline, put a space between # and the headline.
In other words: # Headline, not #Headline.
In addition to Markdown, there are several commands (starting with an @) which automate things to make generating style guides more fun. Commands can be used within and outside of code blocks, but will have a different meaning. Commands available are:
You can import any other *.lsg file at any place within any *.lsg file:
```
// Import a file:
@import folder/file.lsg
// Import a file (`.lsg` will be added by default):
@import folder/file
// Import a file starting with `_` (folder/_file.lsg); this works automatically:
@import folder/file
// Import multiple files:
@import folder/*.lsg
@import folder/*
// Importing from multiple folders:
@import **/*.lsg
@import **/*
// Importing a Haml file (the resulting HTML will be rendered into the style guide):
@import folder/file.haml
@import folder/*.haml
@import **/*.haml
```
All file types supported by Tilt can be imported.
By default, @import is looking for *.lsg files.
A default example outputs the HTML source as:
- Real HTML in a wrapper to display the results
- Syntax-highligted code below
Example:
```
<button class="button">Example button</button>
```
There are more commands to generate output. They start with an @ and can be put in the code block:
You can automatically generate color swatches out of your Sass variables:
@colors {
$light-red $gray $green $red $dark-red $black
}
By clicking the color swatch in the style guide, users can copy the hex code of the color (useful for designers). When pointing the cursor on the variable name, it will be copied on click instead (useful for developers).
The output will respect newlines. The example below will create a 3 × 3 matrix
of color swatches and groups shades in columns which might be more easy to
understand. - leaves a cell empty in the matrix:
@colors {
- $light-red $gray
$green $red -
- $dark-red $black
}
The LivingStyleGuide also supports CSS colors and Sass functions. All of them will work:
@colors {
red #ca1f70 #FFF rgba(0, 0, 0, 0.5)
$my-color my-color-function() lighten(red, 10%) darken($my-color, 20%)
}
This will output the code as HTML but display the syntax highlighted source as Haml (learn how to use Haml by default):
```
@haml
%button.button Example button
```
You can add any CSS to each example if it helps to make it better in the style guide only. For example, add some margin between elements:
```
<button class="button">Example button</button>
<button class="button -primary">Example button</button>
@css {
.button + .button {
margin-left: 3em;
}
}
```
This adds 3em margin between both buttons.
To avoid this to affect other examples, the CSS code will be scoped to this example only (each example automatically gets a unique id).
If you need the same CSS code for several examples, you can put the CSS outside of the example. This way it will be scoped to the current file:
```
<button class="button">Example button</button>
<button class="button -primary">Example button</button>
```
```
<a class="button">Example button</a>
<a class="button -primary">Example button</a>
```
@css {
.button + .button {
margin-left: 3em;
}
}
For Sass you can also use @sass and @scss:
@sass
.button + .button
margin-left: 3em
@scss {
.button + .button {
margin-left: 3em;
}
}
Within the @scss/@sass helper, all variables, mixins, … of your project are
available. For example, if my-styles.scss sets $my-project-margin, you can
write this:
@scss my-styles.scss
@scss {
.button + .button {
margin-left: $my-project-margin;
}
}
It is possible to add Sass code without scoping (works for @css/scss/sass).
@scss scope: global {
.code { ... }
}
Or as a shortcut inspired by Sass’ global variables (for @scss/@sass):
@scss !global {
.code { ... }
}
This will show and execute the JavaScript, e. g. you designed tabs and need few lines of jQuery to bring them alive.
```
@javascript {
$(".button").click(function() {
alert("Hello World!");
});
}
```
Same example but using CoffeeScript. It will be executed as JavaScript and displayed as CoffeeScript:
```
@coffee-script
$(".button").click ->
alert "Hello World!"
```
Show which fonts should be used on your website—this will output and example text block (A—Z, a—z, 0—9, and some special characters) of the given font. It accepts valid CSS like for font: 32px comic sans ms;.
@font-example 32px comic sans ms
Use your own text (defaults to “ABC…\nabc…\n123…\n!&…” if not set):
@font-example 32px comic sans ms {
Schweißgequält zündet Typograf Jakob
verflixt öde Pangramme an.
}
You can require any Ruby file (e.g. for custom commands) or Ruby Gems (e.g. a Compass plugin:
Loads `my-ruby-file.rb`:
@require my-ruby-file
Loads the Susy Gem (must be installed on your system):
@require susy
If you just want to output code with no extras (just like in a normal Markdown file), you only need to add the language:
``` html
<div>Some HTML that just gets syntax-higlighted but not put into the document’s DOM</div>
```
No syntax highlighter:
``` plain
<div>Some HTML that just gets syntax-higlighted but not put into the document’s DOM</div>
```
You can set options to apply to all commands or all commands giving a name. This is useful, when you depend on Haml or other templating engines. Add a list of default commands to your styleguide.html.lsg:
For example without defaults:
@header
@haml
.my-header My Style Guide
```
@haml
.my-example
```
With defaults:
@default type: haml
@header
.my-header My Style Guide
```
.my-example
```
If you want your style guide to work as an API, you might have views already written somewhere else and don’t want to write the same HTML code into the style guide.
First, there is the @data command, which sets local variables to
render the view:
```
<h1><%= foo %></h1>
@type erb
@data {
"foo": "bar"
}
```
This will render as <h1>bar</h1> in the HTML but show the ERB source
below. The data is written using JSON or YAML syntax (as JSON is a subset of
YAML):
```
<h1><%= foo %></h1>
@type erb
@data format: yaml
foo: bar
```
If there is already a view template, let’s name it
views/headline.html.erb, you can use it:
```
@use views/headline.html.erb
@data {
"foo": "bar"
}
```
Note: You don’t need to set the @type as this is taken from the view
template file suffix.
By repeating using the same template with different data, you can show edge cases—like very long user names or missing values—in your style guide.
The examples in the screenshot above use custom headers to have an individual look. You can add whatever HTML you want and some Sass to style it to your styleguide.html.lsg:
@header {
<div class="my-header">
<img src="my-style-guide-logo.svg" alt="My Style Guide">
<h1>My Style Guide</h1>
</div>
}
You can use any templating engine supported by Tilt:
@header type: haml
.my-header
%img(src="my-style-guide-logo.svg" alt="My Style Guide")
%h1 My Style Guide
See Custom Header, just use @footer.
See Custom Header, just use @head. This way you can
add any <meta> tag or link additional files.
Enable search for the style guide:
@search-box
This will add a search box on top of the style guide which commands the content via JavaScript.
You can also customize (e.g. translate) the placeholder for the search box:
@search-box placeholder: Buscar
Most of the design of the style guide itself, is calculated by few variables in the styleguide.html.lsg:
@style font-family: comic sans ms, arial, sans-serif
@style font-size: 7em
@style background-color: red
@style border-color: $my-color
@style color: #eee
@style code-color: darken(red, 10%)
@style color-swatch-border-radius: 0
- For a full list of options, have a look at the source (just strip
$lsg-from the variables). - Every Sass expression is allowed
- Variables defined in your production Sass are available
code-colorgenerates a whole color scheme for syntax highlighting in your corporate colorscolor-swatch-border-radius: 0creates squared color swatches
Just play a bit and create an individual style guide which represents your personal taste :)
If you need external JavaScript files to be included in the style guide, there are two options: before (in the <head>) or after (just before the closing </body>). It accepts a list of URLs (ending with *.js) or plain JavaScript code:
@javascript-before assets/modernizr.js
@javascript-after http://code.jquery.com/jquery-2.1.3.min.js
@javascript-after assets/application.js
@javascript-after {
$(function() {
// custom code
});
}
If you use @javascript or @coffee-script, your application files and jQuery might need to be included in the javascript-before section.
Same example as above, just using CoffeeScript. Note, it is using the indented syntax (no colon but indent following lines by two spaces) which works well with CoffeeScript.
@javascript-before assets/modernizr.js
@javascript-after http://code.jquery.com/jquery-2.1.3.min.js
@javascript-after assets/application.js
@javascript-after transpiler: coffee-script
$ ->
# custom code
