+them to the issue tracker on GitHub: http://github.com/Kronuz/pyScss/issues

+
+Running the test suite
+----------------------
+
+The test suite is built atop the excellent `py.test`_ library, and can be run with::
+
+    py.test
+
+from the root of a source checkout.
+
+.. _py.test: http://pytest.org/latest/
+
+Most of the tests are pairs of input/output files in ``scss/tests/files``; the
+test suite scans for these, compiles all the ``.scss`` files, and compares the
+output with the ``.css`` file of the same name.  You can limit which file tests
+run::
+
+    py.test --test-file-filter=REGEX,REGEX,REGEX...
+
+There are also several tests borrowed from the Ruby and C implementations.
+Many of these don't work (due to missing features, different error messages,
+slightly different formatting, etc.), so to reduce the useless noise produced
+by a test run, you must explicitly opt into them with ``--include-ruby``, even
+when using a file filter.  These files are in the ``from-ruby/`` and
+``from-sassc/`` subdirectories.
+
+Additionally, test files in the ``xfail/`` subdirectory are assumed to fail.
+Other than these cases, the directory names are arbitrary.

+
+Changelog
+---------
+
+1.2.0 (not yet released)
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+This is a significant release that greatly increases compatibility with the
+reference compiler; in particular, the Sass port of Bootstrap now compiles.
+
+There are a lot of changes here, so please feel free to report any bugs you
+see!  The goal is 100% compatibility with the Ruby project.
+
+Missing Sass features
+"""""""""""""""""""""
+
+* Dashes and underscores are treated as interchangeable in variable, function, and mixin names.
+* Rule blocks in the form ``background: red { ... }`` are now supported.
+* Colors are output as their shortest representation, and never as ``hsl()``.  The separate compiler options for compressing colors have been removed.
+* The color modification functions (``adjust-color``, etc.) now work reliably.
+* ``transparent`` is recognized as a color.
+* Unrecognized units are now supported and treated as opaque.
+* Arbitrary combinations of units (e.g., ``px * px``) are supported for intermediate values.  Unit cancellation now works reliably.
+* Comparison and addition are now more in line with the Ruby behavior.
+* ``/`` is now left untouched when it appears between literals, as in ``font: 0 / 0``.
+* ``null`` is supported.
+* ``zip()`` is supported.
+* ``grayscale()`` now knows it's also a CSS3 filter function, and won't be evaluated if its argument is a number.
+* Slurpy arguments (``some-function($args...)``) are supported.
+* ``@extend`` has been greatly improved: it eliminates common ancestors and works in many complex cases that used to produce strange results.
+* Several Compass functions now adhere more closely to Compass's behavior.  ``linear-gradient()`` is less likely to wreck valid CSS3 syntax.
+* Compass's ``e()``, ``pow()``, ``log()``, and ``sqrt()`` are now supported.
+
+Bug fixes
+"""""""""
+
+* Interactive mode works.  Again.
+* Color names in strings and selectors are no longer replaced with hex equivalents.
+* Unrecognized ``@``-rule blocks such as ``@keyframes`` are left alone, rather than being treated like selectors.
+* ``@media`` blocks aren't repeated for every rule inside.
+* Pound-interpolation always drops quotes on strings.
+* Single quoted strings no longer lose their quotes when rendered.
+* ``+ foo { ... }`` is now recognized as a nested block, not an include.
+* ``color-stop()`` and several proposed CSS4 functions no longer produce "unrecognized function" warnings.
+* Several obscure bugs with variable scoping have been fixed, though a couple others remain.
+* Several bugfixes to the C speedups module to bring it in line with the behavior of the pure-Python scanner.
+
+New features
+""""""""""""
+
+* Python 3 support.  As a result, Python 2.5 no longer works; whether this is a bug or a feature is not yet clear.
+* It's possible to write custom Sass functions in Python, though the API for this is not final.
+* Experimental support for the map type and destructuring ``@each``, both unreleased additions to the Ruby project.
+* Added ``background-brushed``.
+
+Backwards-incompatible changes
+""""""""""""""""""""""""""""""
+
+* Configuration via monkeypatching the ``scss`` module no longer works.  Monkeypatch ``scss.config`` instead.
+* ``em`` and ``px`` are no longer compatible.
+* Unrecognized variable names are now a fatal error.
+
+Internals
+"""""""""
+
+* No longer a single 5000-line file!
+* Vastly expanded test suite, including some experimental tests borrowed from the Ruby and C implementations.
+* Parser now produces an AST rather than evaluating expressions during the parse, which allows for heavier caching and fixes some existing cache bugs.
+* The type system has been virtually rewritten; types now act much less like Python types, and compilation uses Sass types throughout rather than mixing Python types with Sass types.
+
+1.1.5 (Feb 15, 2013)
+^^^^^^^^^^^^^^^^^^^^
+
+* ``debug_info`` now properly produces rules that can be used by FireSass and Google Chrome SASS Source Maps.
+* Improved memory usage for large sets of files to be used as sprites.
+* Warns about IE 4095 maximum number of selectors.
+* ``debug_info`` prints info as comments if specified as ``comments``.
+* Better handling of undefined variables.
+* Added CSS filter functions and ``skewX`` ``skewY``.
+* Command line tool and entry point fixed.
+* Fix cache buster URLs when paths already include queries or fragments.
+* Hashable Values.
+
+1.1.4 (Aug 8, 2012)
+^^^^^^^^^^^^^^^^^^^
+
+* Added ``--debug-info`` command line option (for *FireSass* output).
+* Added compass helper function ``reject()``.
+* Added ``undefined`` keyword for undefined variables.
+
+1.1.3 (Jan 9, 2012)
+^^^^^^^^^^^^^^^^^^^
+
+* Support for the new Sass 3.2.0 features (``@content`` and placeholder selectors)
+* Fixed bug with line numbers throwing an exception.
+
+1.1.2 (Jan 3, 2012)
+^^^^^^^^^^^^^^^^^^^
+
+* Regression bug fixed from 1.1.1
+
+1.1.1 (Jan 2, 2012)
+^^^^^^^^^^^^^^^^^^^
+
+* Added optional C speedup module for an amazing boost in scanning speed!
+* Added ``headings``, ``stylesheet-url``, ``font-url``, ``font-files``, ``inline-font-files`` and ``sprite-names``.
+
+1.1.0 (Dec 22, 2011)
+^^^^^^^^^^^^^^^^^^^^
+
+* Added ``min()`` and ``max()`` for lists.
+* Removed exception raise.
+
+1.0.9 (Dec 22, 2011)
+^^^^^^^^^^^^^^^^^^^^
+
+* Optimizations in the scanner.
+* Added ``background-noise()`` for compass-recipes support.
+* ``enumerate()`` and ``range()`` can go backwards. Ex.: ``range(3, 0)`` goes from 3 to 0.
+* Added line numbers and files for errors.
+* Added support for *Firebug* with *FireSass*.
+* ``nth(n)`` is round (returns the ``nth mod len`` item of the list).
+* ``--watch`` added to the command line.
+* Several bugs fixed.
+
+1.0.8 (May 13, 2011)
+^^^^^^^^^^^^^^^^^^^^
+
+* Changed source color (``$src-color``) default to black.
+* Moved the module filename to ``__init__.py`` and module renamed back to scss.

+
+pyScss, a Sass compiler for Python
+==================================
+
+pyScss compiles Scss (Sass), a superset of CSS that is more powerful, elegant
+and easier to maintain than plain-vanilla CSS. The library acts as a CSS source
+code preprocesor which allows you to use variables, nested rules, mixins, and
+have inheritance of rules, all with a CSS-compatible syntax which the
+preprocessor then compiles to standard CSS.
+
+Scss, as an extension of CSS, helps keep large stylesheets well-organized. It
+borrows concepts and functionality from projects such as OOCSS and other similar
+frameworks like as Sass. It's build on top of the original PHP xCSS codebase
+structure but it's been completely rewritten, many bugs have been fixed and it
+has been extensively extended to support almost the full range of Sass' Scss
+syntax and functionality.

+Python API
+==========
+
+Compiling files
+---------------
+
+Very basic usage is simple enough::
+
+    from scss import Scss
+    css = Scss()
+    css.compile("a { color: red + green; }")
+
+
+Configuration
+-------------
+
+There are several configuration variables in the ``scss.config`` module that
+you may wish to change.
+
+``PROJECT_ROOT``: Root of your entire project.  Used only to construct defaults
+for other variables.  Defaults to the root of the pyScss installation, which is
+probably not what you want.
+
+``LOAD_PATHS``: An iterable of paths to search when using``@import``.
+
+``STATIC_ROOT``: Used for finding sprite files.  Defaults to
+``$PROJECT_ROOT/static``.
+
+``ASSETS_ROOT``: Generated sprites are saved here.  Defaults to
+``$STATIC_ROOT/assets``.
+
+``CACHE_ROOT``: Used for storing cached sprite information.  Defaults to
+``ASSETS_ROOT``.
+
+``STATIC_URL``: URL equivalent to ``STATIC_ROOT``.  Defaults to ``static/``.
+
+``ASSETS_URL``: URL equivalent to ``ASSETS_ROOT``.  Defaults to ``static/assets/``.
+
+``SPRTE_MAP_DIRECTION``: Direction in which to arrange sprites in a
+spritesheet.  Defaults to ``vertical``; may be changed to ``horizontal``,
+``diagonal``, or ``smart``.
+
+``VERBOSITY``: Increase spew from the compiler.  Defaults to ``1``.
+
+``DEBUG``: Set to true to make parse errors fatal.  Defaults to false.
+
+.. warning::
+
+    Configuration via monkeypatching is fraught with issues.  If you don't need
+    the Compass sprite functionality, stick with passing ``search_paths`` to
+    the ``Scss`` constructor, and don't touch these variables at all.
+
+    The current plan is to introduce a new mechanism for Compass configuration
+    in 1.3 with deprecation warnings, and remove ``scss.config`` entirely in
+    2.0.
+
+
+Django example
+--------------
+
+A rough example of using pyScss with Django::
+
+    import os
+    import fnmatch
+    
+    import scss
+    
+    from django.conf import settings
+    from django.utils.datastructures import SortedDict
+    from django.contrib.staticfiles import finders
+    
+    
+    def finder(glob):
+        """
+        Finds all files in the django finders for a given glob,
+        returns the file path, if available, and the django storage object.
+        storage objects must implement the File storage API:
+        https://docs.djangoproject.com/en/dev/ref/files/storage/
+        """
+        for finder in finders.get_finders():
+            for path, storage in finder.list([]):
+                if fnmatch.fnmatchcase(path, glob):
+                    yield path, storage
+    
+    
+    # STATIC_ROOT is where pyScss looks for images and static data.
+    # STATIC_ROOT can be either a fully qualified path name or a "finder"
+    # iterable function that receives a filename or glob and returns a tuple
+    # of the file found and its file storage object for each matching file.
+    # (https://docs.djangoproject.com/en/dev/ref/files/storage/)
+    scss.config.STATIC_ROOT = finder
+    scss.config.STATIC_URL = settings.STATIC_URL
+    
+    # ASSETS_ROOT is where the pyScss outputs the generated files such as spritemaps
+    # and compile cache:
+    scss.config.ASSETS_ROOT = os.path.join(settings.MEDIA_ROOT, 'assets/')
+    scss.config.ASSETS_URL = settings.MEDIA_URL + 'assets/'
+    
+    # These are the paths pyScss will look ".scss" files on. This can be the path to
+    # the compass framework or blueprint or compass-recepies, etc.
+    scss.config.LOAD_PATHS = [
+        '/usr/local/www/sass/frameworks/',
+        '/Library/Ruby/Gems/1.8/gems/compass-0.11.5/frameworks/compass/stylesheets/',
+        '/Library/Ruby/Gems/1.8/gems/compass-0.11.5/frameworks/blueprint/stylesheets/',
+    ]
+    
+    # This creates the Scss object used to compile SCSS code. In this example,
+    # _scss_vars will hold the context variables:
+    _scss_vars = {}
+    _scss = scss.Scss(
+        scss_vars=_scss_vars,
+        scss_opts={
+            'compress': True,
+            'debug_info': True,
+        }
+    )
+    
+    # 1. Compile from a string:
+    compiled_css_from_string = _scss.compile('@import "file2"; a {color: red + green; }')
+    
+    # 2. Compile from a file:
+    compiled_css_from_file = _scss.compile(scss_file='file1.scss')
+    
+    # 3. Compile from a set of files (use SortedDict or collections.OrderedDict to
+    # maintain the compile order):
+    _scss._scss_files = SortedDict((
+        ('file2.scss', open('file2.scss').read()),
+        ('file3.scss', open('file3.scss').read()),
+        ('file4.scss', open('file4.scss').read()),
+    ))
+    compiled_css_from_files = _scss.compile()
+
+.. note::
+
+    The API here is likely to be improved in 1.3, to avoid the need for calling
+    underscored functions.
+
+
+Extending pyScss
+----------------
+
+There is some support for adding custom functions from Python, but the API is
+explicitly undocumented and subject to change.  Watch this space.
+
+.. todo::
+
+    Document the extension API once it's final.

+=============
+pyScss syntax
+=============
+
+Supported Sass features
+=======================
+
+pyScss is mostly compatible with Sass 3.2.
+
+
+Both syntaxes
+-------------
+
+SCSS (CSS3 superset) is the primary syntax, but there's experimental support
+for the SASS (YAML-like) syntax.
+
+
+Built-in functions
+------------------
+
+All of the functions described in `the Sass documentation`_ are supported.
+
+.. _the Sass documentation: <http://sass-lang.com/docs/yardoc/Sass/Script/Functions.html
+
+
+Rule nesting
+------------
+
+Rule/selector nesting and the ``&`` parent-reference selector are both
+supported.
+
+Example::
+
+    .selector {
+        a {
+            display: block;
+        }
+        strong {
+            color: blue;
+        }
+    }
+
+Produces::
+
+    .selector a {
+        display: block;
+    }
+    .selector strong {
+        color: blue;
+    }
+
+
+Variables, data types
+---------------------
+
+Variables are supported.  All of the Sass data types—strings, numbers,
+booleans, colors, lists, maps, and null—are supported.
+
+Example::
+
+    $main-color: #ce4dd6;
+    $style: solid;
+    $side: bottom;
+    #navbar {
+        border-#{$side}: {
+            color: $main-color;
+            style: $style;
+        }
+    }
+
+Produces::
+
+    #navbar {
+        border-bottom-color: #ce4dd6;
+        border-bottom-style: solid;
+    }
+
+
+Functions and mixins
+--------------------
+
+``@function``, ``@mixin``, and ``@include`` (optionally with ``@content``) are
+supported.
+
+Named arguments (``foo($name: value)``) and slurpy arguments
+(``foo($args...)``) are also supported.
+
+Example::
+
+    @mixin rounded($side, $radius: 10px) {
+        border-#{$side}-radius: $radius;
+        -moz-border-radius-#{$side}: $radius;
+        -webkit-border-#{$side}-radius: $radius;
+    }
+    #navbar li { @include rounded(top); }
+    #footer { @include rounded(top, 5px); }
+    #sidebar { @include rounded(left, 8px); }
+
+Produces::
+
+    #navbar li {
+        border-top-radius: 10px;
+        -moz-border-radius-top: 10px;
+        -webkit-border-top-radius: 10px;
+    }
+    #footer {
+        border-top-radius: 5px;
+        -moz-border-radius-top: 5px;
+        -webkit-border-top-radius: 5px;
+    }
+    #sidebar {
+        border-left-radius: 8px;
+        -moz-border-radius-left: 8px;
+        -webkit-border-left-radius: 8px;
+    }
+
+
+Rule extension
+--------------
+
+``@extend`` is supported, though some particularly thorny edge cases may not
+produce output identical to the reference compiler.
+
+Example::
+
+    .error {
+        border: 1px #f00;
+        background-color: #fdd;
+    }
+    .error.intrusion {
+        background-image: url("/image/hacked.png");
+    }
+    .seriousError {
+        @extend .error;
+        border-width: 3px;
+    }
+
+Produces::
+
+    .error,
+    .seriousError {
+        border: 1px red;
+        background-color: #fdd;
+    }
+    .error.intrusion,
+    .seriousError.intrusion {
+        background-image: url("/image/hacked.png");
+    }
+    .seriousError {
+        border-width: 3px;
+    }
+
+
+Conditions
+----------
+
+``@if``, ``@else if``, and ``@else`` are supported.
+
+
+Loops
+-----
+
+Both types of iteration are supported::
+
+    @for $n from 1 through 9 {
+        .span-#{$n} { width: $n * 10%; }
+    }
+
+    @each $color in red, blue, yellow {
+        .button-#{$color} {
+            background-color: $color;
+        }
+    }
+
+Additionally, the unpacking-iteration syntax in Sass trunk is supposed; see
+:ref:`maps`.
+
+
+.. _maps:
+
+Maps
+----
+
+pyScss has experimental support for maps, a data type recently added to Sass
+trunk.  Maps are defined with colons inside parentheses::
+
+    $colors: (
+        text: black,
+        background: white
+    );
+
+Keys may be any Sass expression, not just strings.
+
+Maps are manipulated with a handful of map functions::
+
+    a {
+        color: map-get($colors, text);
+        background-color: map-get($colors, background);
+    }
+
+A map is semantically equivalent to a list of 2-lists, stored in the order they
+appeared when the map was defined.  Any list operation will work on a map::
+
+    div {
+        // I don't know why you'd do this  :)
+        margin: nth($colors, 1);  // => text, black
+    }
+
+Maps may be iterated over with ``@each``, of course, but each item will be a
+somewhat clumsy 2-list.  Instead, you can give multiple variables to do an
+unpacking iteration::
+
+    @each $key, $value in $colors {
+        // I don't know why you'd do this either!
+        [data-style=$key] {
+            color: $value;
+        }
+    }
+
+This syntax works on any list-of-lists.
+
+
+Everything is a list
+--------------------
+
+Another change borrowed from Sass trunk: any scalar type (string, number,
+boolean, etc.) will also act as a list of one element when used where a list is
+expected.  This is most useful when writing Python extensions, but may also
+save you from checking ``type-of`` in a complex API.
+
+
+Compass support
+===============
+
+An arbitrary cross-section of Compass 0.11 is supported:
+
+    * **Math functions**: ``sin``, ``cos``, ``tan``, ``round``, ``ceil``, ``floor``, ``pi``, ``e``
+    * **Images**: ``image-url``, ``image-width``, ``image-height``...
+    * **Embedded (inline) images**: ``inline-image``
+
+
+.. todo::
+
+    Document exactly what's supported, how it works, and what's missing.
+
+.. note::
+
+    Currently, Compass support is provided by default, which has led to some
+    surprising behavior since parts of Compass conflict with parts of CSS3.  In
+    the future, Compass will become an extension like it is for Ruby, and you
+    will have to opt in.
+
+
+Sprites
+-------
+
+Example::
+
+    $icons: sprite-map("sociable/*.png"); // contains sociable/facebook.png among others.
+    div {
+        background: $icons;
+    }
+    @each $icon in sprites($icons) {
+        div .#{$icon} {
+            width: image-width(sprite-file($icons, $icon));
+            height: image-height(sprite-file($icons, $icon));
+            background-position: sprite-position($icons, $icon);
+        }
+    }
+
+...generates a new sprite file and produces something like::
+
+    div {
+        background: url("/static/assets/u8Y7yEQL0UffAVw5rX7yhw.png?_=1298240989") 0px 0px no-repeat;
+    }
+    div .facebook {
+        width: 32px;
+        height: 32px;
+        background-position: 0px 0px;
+    }
+    div .twitter {
+        width: 32px;
+        height: 32px;
+        background-position: 0px -32px;
+    }
+    ...
+
+
+pyScss-specific extensions
+==========================
+
+pyScss supports some constructs that upstream Sass does not, for various
+reasons.  Listed here are "blessed" features in no danger of being removed,
+though you should avoid them if you're at all interested in working with the
+reference compiler.
+
+There are also some deviations that only exist for backwards compatibility; you
+should **not** rely on them, they will start spewing warnings at some point in
+the future, and eventually they will disappear.  They are listed separately in
+:ref:`deprecated-features`.
+
+
+``@option``
+-----------
+
+Compiler options may be toggled at runtime with ``@option``.  At the moment the
+only supported option is ``compress``, to control whether the output is
+compressed::
+
+    @option compress: true;
+
+
+Multiplying strings by numbers
+------------------------------
+
+Much like in Python, this works::
+
+    content: "foo" * 3;  // => "foofoofoo"
+
+This is a runtime error in the reference compiler.

+Deprecated features
+===================
+
+Brackets to delimit expressions
+-------------------------------
+
+In an expression, square brackets are equivalent to parentheses::
+
+    margin-top: [1px + 2px] * 3;  // => 9px
+
+This is a holdover from xCSS and will be removed in the future.
+
+
+``extends``
+-----------
+
+There's an alternative syntax for ``@extend``::
+
+    a extends b {
+        ...
+    }
+
+This is identical to::
+
+    a {
+        @extend b;
+        ...
+    }
+
+This is a holdover from xCSS and will be removed in the future.
+
+
+``self`` selector
+-----------------
+
+``self`` is an alias for ``&``::
+
+    a {
+        self:hover {
+            text-decoration: underline;
+        }
+    }
+
+This is a holdover from xCSS and will be removed in the future.
+
+
+``@variables`` block
+--------------------
+
+Variables may be declared in a dedicated block::
+
+    @variables {
+        $color: red;
+    }
+
+``@vars`` is an alias for ``@variables``.
+
+This is a holdover from xCSS and will be removed in the future.
+
+
+``+foo`` to include a mixin
+---------------------------
+
+This::
+
+    div {
+        +border-radius 3px;
+    }
+
+Is equivalent to this::
+
+    div {
+        @include border-radius(3px);
+    }
+
+This is the same as the Sass syntax, but causes some parsing ambiguity, since
+``+foo`` with a block could be either a nested CSS block with a sibling
+selector or a mixin call.  Its future is uncertain, but you should probably
+avoid using it in SCSS files.
+
+Soft errors
+-----------
+
+pyScss is much more liberal in what it accepts than the reference compiler; for
+example, rules at the top level and missing closing braces are accepted without
+complaint, and attempting to use a non-existent mixin only results in a
+warning.
+
+pyScss 2.0 is likely to be much stricter; don't rely on any particular abuse of
+syntax to work in the future.
+
+
+Unsupported Sass features
+=========================
+
+Some Sass features are not supported or have some gaps.  Each of these may be
+considered a bug.
+
+``@while``
+----------
+
+The ``@while`` construct doesn't work at all and will be left intact in the
+output, like any other unrecognized ``@``-rule.

+Installation and usage
+======================
+
+Installation
+------------
+
+pyScss requires only Python 2.5 or later, including Python 3.x.  Install with
+pip::
+
+    pip install pyScss
+
+Its lone dependency is the ``six`` library, which pip should install for you.
+
+
+Usage
+-----
+
+Run from the command line by using ``-m``::
+
+    python -mscss < file.scss
+
+Specify directories to search for imports with ``-I``.  See ``python -mscss
+--help`` for more options.
+
+.. note::
+
+    ``-mscss`` will only work in Python 2.7 and above.  For Python 2.5 and 2.6,
+    ``-m`` doesn't work with packages, and you need to invoke::
+
+        python -mscss.tool
+
+
+
+Interactive mode
+----------------
+
+To get a REPL::
+
+    python -mscss --interactive
+
+Example session::
+
+    $ python scss.py --interactive
+    >>> @import "compass/css3"
+    >>> show()
+    ['functions', 'mixins', 'options', 'vars']
+    >>> show(mixins)
+    ['apply-origin',
+        'apply-transform',
+        ...
+        'transparent']
+    >>> show(mixins, transparent)
+    @mixin transparent() {
+        @include opacity(0);
+    }
+    >>> 1px + 5px
+    6px
+    >>> _
+
+
+Compass example
+---------------
+
+With ``--load-path`` or ``scss.config.LOAD_PATHS`` set to Compass and Blueprint
+roots, you can compile with Compass like with the following::
+
+    @option compress: no;
+
+    $blueprint-grid-columns : 24;
+    $blueprint-grid-width   : 30px;
+    $blueprint-grid-margin  : 10px;
+    $font-color             : #333;
+
+    @import "compass/reset";
+    @import "compass/utilities";
+    @import "blueprint";
+
+    // your code...
