+# Sass [](http://badge.fury.io/rb/sass) [](http://inch-ci.org/github/sass/sass)
+
+**Sass makes CSS fun again**. Sass is an extension of CSS3,
+adding nested rules, variables, mixins, selector inheritance, and more.
+It's translated to well-formatted, standard CSS
+using the command line tool or a web-framework plugin.
+
+Sass has two syntaxes. The new main syntax (as of Sass 3)
+is known as "SCSS" (for "Sassy CSS"),
+and is a superset of CSS3's syntax.
+This means that every valid CSS3 stylesheet is valid SCSS as well.
+SCSS files use the extension `.scss`.
+
+The second, older syntax is known as the indented syntax (or just "Sass").
+Inspired by Haml's terseness, it's intended for people
+who prefer conciseness over similarity to CSS.
+Instead of brackets and semicolons,
+it uses the indentation of lines to specify blocks.
+Although no longer the primary syntax,
+the indented syntax will continue to be supported.
+Files in the indented syntax use the extension `.sass`.
+
+## Using
+
+Sass can be used from the command line
+or as part of a web framework.
+The first step is to install the gem:
+
+ gem install sass
+
+After you convert some CSS to Sass, you can run
+
+ sass style.scss
+
+to compile it back to CSS.
+For more information on these commands, check out
+
+ sass --help
+
+To install Sass in Rails 2,
+just add `config.gem "sass"` to `config/environment.rb`.
+In Rails 3, add `gem "sass"` to your Gemfile instead.
+`.sass` or `.scss` files should be placed in `public/stylesheets/sass`,
+where they'll be automatically compiled
+to corresponding CSS files in `public/stylesheets` when needed
+(the Sass template directory is customizable...
+see [the Sass reference](http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#template_location-option)
for details).
+
+Sass can also be used with any Rack-enabled web framework.
+To do so, just add
+
+```ruby
+require 'sass/plugin/rack'
+use Sass::Plugin::Rack
+```
+
+to `config.ru`.
+Then any Sass files in `public/stylesheets/sass`
+will be compiled into CSS files in `public/stylesheets` on every request.
+
+To use Sass programmatically,
+check out the [YARD documentation](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#using_sass).
+
+## Formatting
+
+Sass is an extension of CSS
+that adds power and elegance to the basic language.
+It allows you to use [variables][vars], [nested rules][nested],
+[mixins][mixins], [inline imports][imports],
+and more, all with a fully CSS-compatible syntax.
+Sass helps keep large stylesheets well-organized,
+and get small stylesheets up and running quickly,
+particularly with the help of
+[the Compass style library](http://compass-style.org).

+
+Sass has two syntaxes.
+The one presented here, known as "SCSS" (for "Sassy CSS"),
+is fully CSS-compatible.
+The other (older) syntax, known as the indented syntax or just "Sass",
+is whitespace-sensitive and indentation-based.
+For more information, see the [reference documentation][syntax].
+
+[syntax]: http://sass-lang.com/documentation/file.SASS_REFERENCE.html#syntax
+
+To run the following examples and see the CSS they produce,
+put them in a file called `test.scss` and run `sass test.scss`.
+
+### Nesting
+
+Sass avoids repetition by nesting selectors within one another.
+The same thing works for properties.
+
+```scss
+table.hl {
+ margin: 2em 0;
+ td.ln { text-align: right; }
+}
+
+li {
+ font: {
+ family: serif;
+ weight: bold;
+ size: 1.2em;
+ }
+}
+```
+
+### Variables
+
+Use the same color all over the place?
+Need to do some math with height and width and text size?
+Sass supports variables, math operations, and many useful functions.
+
+```scss
+$blue: #3bbfce;
+$margin: 16px;
+
+.content_navigation {
+ border-color: $blue;
+ color: darken($blue, 10%);
+}
+
+.border {
+ padding: $margin / 2;
+ margin: $margin / 2;
+ border-color: $blue;
+}
+```
+
+### Mixins
+
+Even more powerful than variables,
+mixins allow you to re-use whole chunks of CSS,
+properties or selectors.
+You can even give them arguments.
+
+```scss
+ mixin table-scaffolding {
+ th {
+ text-align: center;
+ font-weight: bold;
+ }
+ td, th { padding: 2px; }
+}
+
+ mixin left($dist) {
+ float: left;
+ margin-left: $dist;
+}
+
+#data {
+ @include left(10px);
+ @include table-scaffolding;
+}
+```
+
+A comprehensive list of features is available
+in the [Sass reference](http://sass-lang.com/documentation/file.SASS_REFERENCE.html).
+
+## Executables
+
+The Sass gem includes several executables that are useful
+for dealing with Sass from the command line.
+
+### `sass`
+
+The `sass` executable transforms a source Sass file into CSS.
+See `sass --help` for further information and options.
+
+### `sass-convert`
+
+The `sass-convert` executable converts between CSS, Sass, and SCSS.
+When converting from CSS to Sass or SCSS,
+nesting is applied where appropriate.
+See `sass-convert --help` for further information and options.
+
+### Running locally
+
+To run the Sass executables from a source checkout instead of from rubygems:
+
+```
+$ cd <SASS_CHECKOUT_DIRECTORY>
+$ bundle
+$ bundle exec sass ...
+$ bundle exec scss ...
+$ bundle exec sass-convert ...
+```
+
+## Authors
+
+Sass was envisioned by [Hampton Catlin](http://www.hamptoncatlin.com)
+(@hcatlin). However, Hampton doesn't even know his way around the code anymore
+and now occasionally consults on the language issues. Hampton lives in San
+Francisco, California and works as VP of Technology
+at [Moovweb](http://www.moovweb.com/).
+
+[Natalie Weizenbaum](http://nex-3.com) is the primary developer and architect of
+Sass. Her hard work has kept the project alive by endlessly answering forum
+posts, fixing bugs, refactoring, finding speed improvements, writing
+documentation, implementing new features, and getting Hampton coffee (a fitting
+task for a girl genius). Natalie lives in Seattle, Washington and works on
+[Dart](http://dartlang.org) application libraries at Google.
+
+[Chris Eppstein](http://acts-as-architect.blogspot.com) is a core contributor to
+Sass and the creator of Compass, the first Sass-based framework. Chris focuses
+on making Sass more powerful, easy to use, and on ways to speed its adoption
+through the web development community. Chris lives in San Jose, California with
+his wife and daughter. He is an Engineer for
+[LinkedIn.com](http://linkedin.com), where one of his responsibilities is to
+maintain Sass & Compass.
+
+If you use this software, you must pay Hampton a compliment. And buy Natalie
+some candy. Maybe pet a kitten. Yeah. Pet that kitty.
+
+Beyond that, the implementation is licensed under the MIT License.
+Okay, fine, I guess that means compliments aren't __required__.

+ #

+ # Importers without a notion of "relative paths"

+ #
+ # See \{#find} for important information on how this method should behave.
+ #
+ # The `:filename` option passed to the returned {Sass::Engine}
+ # should be of a format that could be passed to \{#find}.
+ #
+ # @param uri [String] The URI to import. This is not necessarily relative,
+ # but this method should only return true if it is.
+ # @param base [String] The base filename. If `uri` is relative,

+ # If not, return nil.
+ # * Read the file and place the contents in a {Sass::Engine}.

+ #
+ # If this importer's format allows for file extensions,
+ # it should treat them the same way as the default {Filesystem} importer.
+ # If the URI explicitly has a `.sass` or `.scss` filename,

+ # and import it as the syntax indicated.
+ # If it doesn't exist, the importer should return nil.

+ # The class handles `.s[ca]ss` file staleness checks via their mtime timestamps.
+ #
+ # To speed things up two level of caches are employed:
+ #
+ # * A class-level dependency cache which stores @import paths for each file.
+ # This is a long-lived cache that is reused by every StalenessChecker instance.
+ # * Three short-lived instance-level caches, one for file mtimes,
+ # one for whether a file is stale during this particular run.
+ # and one for the parse tree for a file.
+ # These are only used by a single StalenessChecker instance.
+ #
+ # Usage:
+ #
+ # * For a one-off staleness check of a single `.s[ca]ss` file,
+ # the class-level {stylesheet_needs_update?} method
+ # should be used.
+ # * For a series of staleness checks (e.g. checking all files for staleness)
+ # a StalenessChecker instance should be created,
+ # and the instance-level \{#stylesheet\_needs\_update?} method should be used.
+ # the caches should make the whole process significantly faster.
+ # *WARNING*: It is important not to retain the instance for too long,
+ # as its instance-level caches are never explicitly expired.

+ # \{#unique_id unique-id()}
+ # : Returns a unique CSS identifier.
+ #
+ # ## Adding Custom Functions
+ #
+ # New Sass functions can be added by adding Ruby methods to this module.
+ # For example:
+ #
+ # module Sass::Script::Functions
+ # def reverse(string)
+ # assert_type string, :String
+ # Sass::Script::Value::String.new(string.value.reverse)
+ # end
+ # declare :reverse, [:string]
+ # end
+ #
+ # Calling {declare} tells Sass the argument names for your function.
+ # If omitted, the function will still work, but will not be able to accept keyword arguments.
+ # {declare} can also allow your function to take arbitrary keyword arguments.
+ #
+ # There are a few things to keep in mind when modifying this module.
+ # First of all, the arguments passed are {Value} objects.
+ # Value objects are also expected to be returned.
+ # This means that Ruby values must be unwrapped and wrapped.
+ #
+ # Most Value objects support the {Value::Base#value value} accessor for getting
+ # their Ruby values. Color objects, though, must be accessed using
+ # {Sass::Script::Value::Color#rgb rgb}, {Sass::Script::Value::Color#red red},
+ # {Sass::Script::Value::Color#blue green}, or {Sass::Script::Value::Color#blue
+ # blue}.
+ #
+ # Second, making Ruby functions accessible from Sass introduces the temptation
+ # to do things like database access within stylesheets.
+ # This is generally a bad idea;
+ # since Sass files are by default only compiled once,
+ # dynamic code is not a great fit.
+ #
+ # If you really, really need to compile Sass on each request,
+ # first make sure you have adequate caching set up.
+ # Then you can use {Sass::Engine} to render the code,
+ # using the {file:SASS_REFERENCE.md#custom-option `options` parameter}
+ # to pass in data that {EvaluationContext#options can be accessed}
+ # from your Sass functions.
+ #
+ # Within one of the functions in this module,
+ # methods of {EvaluationContext} can be used.
+ #
+ # ### Caveats
+ #
+ # When creating new {Value} objects within functions, be aware that it's not
+ # safe to call {Value::Base#to_s #to_s} (or other methods that use the string
+ # representation) on those objects without first setting {Tree::Node#options=
+ # the #options attribute}.

+ # parsing it as a declaration value. If this fails, backtrack and parse
+ # it as a selector.

+The Listen gem listens to file modifications and notifies you about the changes.
+
+## Features
+
+* Works everywhere!
+* Supports watching multiple directories from a single listener.
+* OS-specific adapters for Mac OS X 10.6+, Linux, *BSD and Windows.
+* Automatic fallback to polling if OS-specific adapter doesn't work.
+* Detects file modification, addition and removal.
+* File content checksum comparison for modifications made under the same second.
+* Allows supplying regexp-patterns to ignore and filter paths for better results.
+* Tested on all Ruby environments via [Travis CI](https://travis-ci.org/guard/listen).
+
+## Pending features
+
+Still not implemented, pull requests are welcome.
+
+* Symlinks support. [#25](https://github.com/guard/listen/issues/25)
+* Signal handling. [#105](https://github.com/guard/listen/issues/105)
+* Non-recursive directory scanning. [#111](https://github.com/guard/listen/issues/111)
+
+## Install
+
+### Using Bundler
+
+The simplest way to install Listen is to use Bundler.
+
+Add Listen to your Gemfile:
+
+```ruby
+group :development do
+ gem 'listen'
+end
+```
+
+and install it by running Bundler:
+
+```bash
+$ bundle
+```
+
+### Install the gem with RubyGems
+
+```bash
+$ gem install listen
+```
+
+### On Windows
+
+If your are on Windows and using Ruby MRI >= 1.9.2 you can try to use the
[`wdm`](https://github.com/Maher4Ever/wdm) instead of polling.
+Please add the following to your Gemfile:
+
+```ruby
+require 'rbconfig'
+gem 'wdm', '>= 0.1.0' if RbConfig::CONFIG['target_os'] =~ /mswin|mingw/i
+```
+
+## Usage
+
+There are **two ways** to use Listen:
+
+1. Block API: Call `Listen.to`/`Listen.to!` with either a single directory or multiple directories, then
define the `change` callback in a block.
+2. "Object" API: Create a `listener` object and use it in a chainable way.
+
+### Block API
+
+``` ruby
+# Listen to a single directory.
+Listen.to('dir/path/to/listen', :filter => /\.rb$/, :ignore => %r{ignored/path/}) do |modified, added,
removed|
+ # ...
+end
+
+# Listen to multiple directories.
+Listen.to('dir/to/awesome_app', 'dir/to/other_app', :filter => /\.rb$/, :latency => 0.1) do |modified,
added, removed|
+ # ...
+end
+```
+
+### "Object" API
+
+``` ruby
+listener = Listen.to('dir/path/to/listen')
+listener = listener.ignore(%r{^ignored/path/})
+listener = listener.filter(/\.rb$/)
+listener = listener.latency(0.5)
+listener = listener.force_polling(true)
+listener = listener.polling_fallback_message(false)
+listener = listener.force_adapter(Listen::Adapters::Linux)
+listener = listener.change(&callback)
+listener.start
+```
+
+**Note**: All the "Object" API methods except `start`/`start!` return the listener
+and are thus chainable:
+
+``` ruby
+Listen.to('dir/path/to/listen')
+ .ignore(%r{^ignored/path/})
+ .filter(/\.rb$/)
+ .latency(0.5)
+ .force_polling(true)
+ .polling_fallback_message('custom message')
+ .change(&callback)
+ .start
+```
+
+### Pause/Unpause
+
+Listener can also easily be paused/unpaused:
+
+``` ruby
+listener = Listen.to('dir/path/to/listen')
+listener.start # non-blocking mode
+listener.pause # stop listening to changes
+listener.paused? # => true
+listener.unpause # start listening to changes again
+listener.stop # stop completely the listener
+```
+
+## Changes callback
+
+Changes to the listened-to directories gets reported back to the user in a callback.
+The registered callback gets invoked, when there are changes, with **three** parameters:
+`modified_paths`, `added_paths` and `removed_paths` in that particular order.
+
+You can register a callback in two ways. The first way is by passing a block when calling
+the `Listen.to`/`Listen.to!` method or when initializing a listener object:
+
+```ruby
+Listen.to('path/to/app') do |modified, added, removed|
+ # This block will be called when there are changes.
+end
+
+# or ...
+
+listener = Listen::Listener.new('path/to/app') do |modified, added, removed|
+ # This block will be called when there are changes.
+end
+
+```
+
+The second way to register a callback is by calling the `#change` method on a
+listener passing it a block:
+
+```ruby
+# Create a callback
+callback = Proc.new do |modified, added, removed|
+ # This proc will be called when there are changes.
+end
+
+listener = Listen.to('dir')
+listener.change(&callback) # convert the callback to a block and register it
+
+listener.start
+```
+
+### Paths in callbacks
+
+Listeners invoke callbacks passing them absolute paths by default:
+
+```ruby
+# Assume someone changes the 'style.css' file in '/home/user/app/css' after creating
+# the listener.
+Listen.to('/home/user/app/css') do |modified, added, removed|
+ modified.inspect # => ['/home/user/app/css/style.css']
+end
+```
+
+#### Relative paths in callbacks
+
+When creating a listener for a **single** path (more specifically a `Listen::Listener` instance),
+you can pass `:relative_paths => true` as an option to get relative paths in
+your callback:
+
+```ruby
+# Assume someone changes the 'style.css' file in '/home/user/app/css' after creating
+# the listener.
+Listen.to('/home/user/app/css', :relative_paths => true) do |modified, added, removed|
+ modified.inspect # => ['style.css']
+end
+```
+
+Passing the `:relative_paths => true` option won't work when listening to multiple
+directories:
+
+```ruby
+# Assume someone changes the 'style.css' file in '/home/user/app/css' after creating
+# the listener.
+Listen.to('/home/user/app/css', '/home/user/app/js', :relative_paths => true) do |modified, added, removed|
+ modified.inspect # => ['/home/user/app/css/style.css']
+end
+```
+
+## Options
+
+All the following options can be set through the `Listen.to`/`Listen.to!` params
+or via ["Object" API](#object-api) methods:
+
+```ruby
+:ignore => %r{app/CMake/}, /\.pid$/ # Ignore a list of paths (root directory or sub-dir)
+ # default: See DEFAULT_IGNORED_DIRECTORIES and
DEFAULT_IGNORED_EXTENSIONS in Listen::DirectoryRecord
+
+:filter => /\.rb$/, /\.coffee$/ # Filter files to listen to via a regexps list.
+ # default: none
+
+:latency => 0.5 # Set the delay (**in seconds**) between checking for changes
+ # default: 0.25 sec (1.0 sec for polling)
+
+:force_adapter => Listen::Adapters::Linux # Force the use of a particular adapter class
+ # default: none
+
+:force_polling => true # Force the use of the polling adapter
+ # default: none
+
+:polling_fallback_message => 'custom message' # Set a custom polling fallback message (or disable it with
false)
+ # default: "Listen will be polling for changes. Learn more at
https://github.com/guard/listen#polling-fallback.";
+
+:relative_paths => true # Enable the use of relative paths in the callback.
+ # default: false
+```
+
+### Note on the patterns for ignoring and filtering paths
+
+Just like the unix convention of beginning absolute paths with the
+directory-separator (forward slash `/` in unix) and with no prefix for relative paths,
+Listen doesn't prefix relative paths (to the watched directory) with a directory-separator.
+
+Therefore make sure _NOT_ to prefix your regexp-patterns for filtering or ignoring paths
+with a directory-separator, otherwise they won't work as expected.
+
+As an example: to ignore the `build` directory in a C-project, use `%r{build/}`
+and not `%r{/build/}`.
+
+Use `#filter!` and `#ignore!` methods to overwrites default patterns.
+
+## Blocking listening to changes
+
+Calling `Listen.to` with a block doesn't block the current thread. If you want
+to block the current thread instead until the listener is stopped (which needs
+to be done from another thread), you can use `Listen.to!`.
+
+Similarly, if you're using the "Object" API, you can use `#start!` instead of `#start` to block the
+current thread until the listener is stopped.
+
+Here is an example of using a listener in the blocking mode:
+
+```ruby
+Listen.to!('dir/path/to/listen') # block execution
+
+# Code here will not run until the listener is stopped
+
+```
+
+Here is an example of using a listener started with the "Object" API in blocking mode:
+
+```ruby
+listener = Listen.to('dir/path/to/listen')
+listener.start! # block execution
+
+# Code here will not run until the listener is stopped
+
+```
+
+**Note**: Using the `Listen.to!` helper-method with or without a callback-block
+will always start the listener right away and block execution of the current thread.
+
+## Listen adapters
+
+The Listen gem has a set of adapters to notify it when there are changes.
+There are 4 OS-specific adapters to support Mac, Linux, *BSD and Windows.
+These adapters are fast as they use some system-calls to implement the notifying function.
+
+There is also a polling adapter which is a cross-platform adapter and it will
+work on any system. This adapter is unfortunately slower than the rest of the adapters.
+
+The Listen gem will choose the best and working adapter for your machine automatically. If you
+want to force the use of the polling adapter, either use the `:force_polling` option
+while initializing the listener or call the `#force_polling` method on your listener
+before starting it.
+
+It is also possible to force the use of a particular adapter, by using the `:force_adapter`
+option. This option skips the usual adapter choosing mechanism and uses the given
+adapter class instead. The adapter choosing mechanism requires write permission
+to your watched directories and will needlessly load code, which isn't always desirable.
+
+## Polling fallback
+
+When a OS-specific adapter doesn't work the Listen gem automatically falls back to the polling adapter.
+Here are some things you could try to avoid the polling fallback:
+
+* [Update your Dropbox client](http://www.dropbox.com/downloading) (if used).
+* Increase latency. (Please [open an issue](https://github.com/guard/listen/issues/new)
+if you think that default is too low.)
+* Move or rename the listened folder.
+* Update/reboot your OS.
+
+If your application keeps using the polling-adapter and you can't figure out why, feel free to [open an
issue](https://github.com/guard/listen/issues/new) (and be sure to [give all the
details](https://github.com/guard/listen/blob/master/CONTRIBUTING.md)).
