libsass-python's Introduction

Sass makes CSS fun again. Sass is an extension of CSS, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a plugin for your build system.

$font-stack: Helvetica, sans-serif;
$primary-color: #333;

body {
  font: 100% $font-stack;
  color: $primary-color;
}

@mixin border-radius($radius) {
  -webkit-border-radius: $radius;
     -moz-border-radius: $radius;
      -ms-border-radius: $radius;
          border-radius: $radius;
}

nav {
  ul {
    margin: 0;
    padding: 0;
    list-style: none;
  }

  li { @include border-radius(10px); }

  a {
    display: block;
    padding: 6px 12px;
    text-decoration: none;
  }
}

Install Sass

You can install Sass on Windows, Mac, or Linux by downloading the package for your operating system from GitHub and adding it to your PATH. That's all—there are no external dependencies and nothing else you need to install.

If you use Node.js, you can also install Sass using npm by running

npm install -g sass

However, please note that this will install the pure JavaScript implementation of Sass, which runs somewhat slower than the other options listed here. But it has the same interface, so it'll be easy to swap in another implementation later if you need a bit more speed!

See the Sass website for more ways to install Sass.

Once you have Sass installed, you can run the sass executable to compile .sass and .scss files to .css files. For example:

sass source/stylesheets/index.scss build/stylesheets/index.css

Learn Sass

This Repository

This repository isn't an implementation of Sass. Those live in sass/dart-sass and sass/libsass. Instead, it contains:

spec/, which contains specifications for language features.
proposal/, which contains in-progress proposals for changes to the language.
accepted/, which contains proposals that have been accepted and are either implemented or in the process of being implemented.

Note that this doesn't contain a full specification of Sass. Instead, feature specifications are written as needed when a new feature is being designed or when an implementor needs additional clarity about how something is supposed to work. This means many of the specs in spec/ only cover small portions of the features in question.

Versioning Policy

The proposals in this repository are versioned, to make it easy to track changes over time and to refer to older versions. Every version has a Git tag of the form proposal.<name>.draft-<version>. A new version should be created for each batch of changes.

Every version has a major version, and they may have a minor version as well (indicated <major>.<minor>). The minor version should be incremented for changes that don't affect the intended semantics of the proposal; otherwise, the major version should be incremented.

libsass-python's Issues

Suggested api changes

I think it would simplify the code to expose the following instead of compile:

def compile_string(s, **kwargs):
    # ...

# and

def compile_file(filename, **kwargs):
    # ...

and drop compile_directory (libsass has hard deprecated it)

libsass-0.5.1-cp27-none-win32.whl Fails to install on Windows 8.1

I am running Windows 8.1 64-bit.
I always run Python 2.7 in 32-bit mode
I installed libsass both via PIP & via the downloaded wheel.
Both times it fails in the same way when I try to import sass:

import sass
Traceback (most recent call last):
File "", line 1, in
File "c:\bin\python27\lib\site-packages\sass.py", line 21, in
from _sass import (OUTPUT_STYLES, SOURCE_COMMENTS, compile_dirname,
ImportError: DLL load failed: The specified module could not be found.

_sass.pyd is present in the same folder as sass.py

I don't have any Visual Studio to try & compile a version myself.
Are there any Win32 libs which I need installing on my system to get this working?

Cut 0.7.0 release

Error compiling with compass

I'm getting this error when trying to include compass:
"tmp/compass/compass/_support.scss:152: named arguments must precede variable-length argument"

Line 152 of _support.scss contains:
@include for-legacy-browser($browser, $range..., $threshold: $threshold, $ranges: $browsers) {

My code contains:
source = '@import "compass"; .... some styles here ....'
src_directories = ['tmp/somestyles', '/tmp/compass/']
compiled = sass.compile(string=source,include_paths=src_directories)

I'm using the latest version of Compass from Jan 15 (compass-1.0.3) and version 0.7.0 of libsass

Thanks!

Let's ship 0.8.0

Since we've bumped libsass to 3.2 let's release!

builder.Manifest.build_one recursive css_path

If I try to use builder.Manifest.build_one to build a single .scss file the output .css file get's place 2 iterations of css-path down.

e.g
manifest = builder.Manifest(sass_path='static/sass', css_path='./static/css')
manifest.build_one('.','blog.scss')

will result in 'blog.scss.css' being placed at 'static/css/static/css'

I think line 182 in builder.py should read

css_path = os.path.join(package_dir, css_filename)

rather than

css_path = os.path.join(package_dir, self.css_path, css_filename)

Parsing error throws error message infinitely on watch mode

I think the lib should handle parse error exception in watch mode.

Add import callback functionality recently incorporated into libsass

As per this issue thread...

sass/libsass#21 (comment)

...libsass now permits import callbacks that return source strings. This allows systems using libsass to pull source files from the network, or database, or whatever location without having to use the filesystem.

Broken behavior with media queries

We've been having some issues with media queries and libsass. Specifically we get a great Segmentation fault: 11 when using them at all.

Tried against current PyPI version and git HEAD

Minimal test case can be found here:

https://gist.github.com/3995613

High memory usage during compilation

I've been having some trouble (pip) installing libsass in a container, seemingly because the compiler runs out of memory (my Docker host VM has about 300 MB free) and gets killed.

$ docker run -i -t python:3.4 pip install libsass

By way of comparison (not sure if it's a valid comparison or not), Numpy compiles just fine, using less than half the memory when trying to compile libsass. Can any compilation arguments be added to allow building on more meager VMs?

output style documentation

libsass-python document,

output_style (str) – an optional coding style of the compiled result. choose one of: nested (default), expanded, compact, compressed

But there are no differences between nested, expanded, compact output_style of sass.compile. I was puzzled over this parameter.

>>> import sass
>>> scss_str = """nav {
...   ul {
...     margin: 0;
...     padding: 0;

>>> nested = sass.compile(string=scss_str, output_style="nested")

Thanks.

Enable passing compressing option to sassutils.distutils.build_sass

Currently it is not available to pass sass.compile options.

Consider include wheel: cp27 + win32

I'm trying to install libsass-python on CPython27 win32.

I have VS C++ 2008 but it can't compile libsass. I tryed to install from wheels but theres only a adm_64 option.

Can you please include a win32 version?

If not, can you help me get this working? What I need to do?

Thanks.

More feedback on the compilation process - suggestion

Hi,

The guy using sass on my team asked me yesterday if there was a flag or something so he can just be watching the Flask console to see if something failed while changing his sass files instead of going to the generated file to see details on the exception. I couldn't find any and ended up adding:

print '*' * 80
print repr(e)
print '*' * 80

inside SassMiddleware.__call__ to get any exception info from any CompileError. This is absolutely raw but seems to be useful.

Maybe something nicer can be added, like a parameter to send errors to stderr or something like that.

Thanks,

Federico

Update to libsass 3.1.0

https://github.com/sass/libsass/releases

Move docs to ReadTheDocs.org

The docs is currently hosted on GitHub Pages, but it would be better if it’s moved to RTD.org.

New release?

It'd be nice if the latest changes were on pypi…

Source maps generation complaints

libsass produce local path in source comments, like /Users/username/path/to/project/file.scss, that I don't actually need in my production compressed files. But, on the other hand, i want to generate source map files. Currently I can't see how to solve this

Can't install on freebsd 9.3

For some reason I cannot get libsass to install using pip in my freebsd 9.3 jail. I did have it installed earlier only I had to create a new clean jail today and now it won't install.

I've tried with clang 3.4.1, gcc 4.8 and clang 3.6. They all fail in a similar way. Clang 3.4.1 is default.

Do I have to build the dll?

I installed (pip install libsass) , and got 'Successfully installed'. However, there is an error when
'import sass':

Document how to compile Sass syntax from a string.

Maybe I'm just slow today but I am having a tough time puzzling this out...

>>> print open('file.sass').read()
body
    font: sans-serif
    p
        font-weight: bold

>>> import sass
>>> print sass.compile(filename='file.sass')
body {
  font: sans-serif; }
  body p {
    font-weight: bold; }

>>> print sass.compile(string=open('file.sass').read())
Traceback (most recent call last):
...
CompileError: Error: invalid top-level expression
        on line 1 of stdin
>> body
   ^

What am I doing wrong? I searched the "References" part of the docs for 'SCSS' and found nothing, I can't seem to figure out how to tell sass.compile(string=...) that I want Sass syntax and not SCSS.

PyPi release

Hi, just a friendly reminder to publish 0.8.2 to pypi (we need one of the fixes in libsass 3.2.4). In the meantime we are pip installing via git.

Thanks!

Python 3 support

Hey, I was wondering if support for Python 3 is planned. It currently does not install, the unit tests do not run and the dependencies needed for the unit tests don't support Python 3.

I'm attemping to make it work in Python 3 and so far I've managed to make the package install and run the compile function (only with byte strings). Next step is unicode. ☃

The dependencies need to be replaced since they don't support Python 3. Attest is supposed to work, but it's dependency, progressbar doesn't work. I don't know what Werkzeug's status is.

Package installation
Importing the Sass module
Compile Sass text (only byte strings)
Use unicode strings instead of byte strings
Find replacements for the Python 2 only modules used in the unit tests
Redo the unit tests
Test everything with Python 2, Python 3 and PyPy

error compiling glyph fonts

I attempted to use libsass as a way to integrate Materialize css (http://materializecss.com) into my django stack.

I was simply using sassc to compile the materialize.scss file and libsass strips the content value out of the out going css.

Something that should compile to this
.mdi-navigation-menu:before{content:"\e8a1"}

Compiles to this
.mdi-navigation-menu:before {content: ; }

If you have any other questions about how I found this error feel free message me for more details.

Strip Sass extension from output file

Using this simple script here:

import sassutils.builder

result = sassutils.builder.build_directory(".", ".", "compressed")
print(result)  # Outputs {'style.scss': 'style.scss.css'}

And indeed, the output file name is style.scss.css. Ideally it should be called simply style.css. :)

I've got this working fine on my OSX dev box, so too bad.

Work with python-scss

This isn't really a bug. I just wanted to point out the other python wrapper here: https://github.com/pistolero/python-scss I haven't really looked too deeply into whether one is better than the other. However, I do see that python-scss uses libsass as a git subrepo, which might be a better idea if you don't intend the Python stuff to be merged with libsass. Anyway, I think it would be better to pool resources, don't confuse users by having two wrappers, etc.

Variable substitution in @media rules

This doesn't work, but probably should:

$foo: 3;
@media (max-width: $foo) {
  body { color: black; }
}

Comparing output from ruby-based sass with python-based sassc:

$ sass t.scss > sass.css
$ sassc t.scss > sassc.css
$ diff sass.css sassc.css
1c1
< @media (max-width: 3) {

---
> @media (max-width: $foo) {
3a4
>

Given there's a test for this in the underlying C libsass, I assume this project is just carrying an older version of the library?

Crash with media queries

$ python -c "import sass; sass.compile(filename='crash.scss')"
Segmentation fault (core dumped)

content of crash.scss is just:

@media (max-width:979px) { }

Build fails on Heroku

Glad to hear that libsass-python is again compatible with older GCC versions.
However when I try to deploy my app to Heroku with libsass-python 0.6.2, it still fails.

Compiling on CentOS 6 (GCC 4.4) failure

README still says GCC (G++) 4.3+ is needed but apparently that's no longer true because anything newer than libsass-python 0.5.0 fails on CentOS 6. That seems to include the 0.6.2 version as well, which explicitly state that 0.6.0 through 0.6.1 had issues ...?

Upgrade to libsass 3.2.5

3.2.4 has a regression, failing compilation on certain selectors:

sass/libsass#1214

docs on using with Flask should mention jinja-assets-compressor

https://github.com/jaysonsantos/jinja-assets-compressor

3.1.0 link is broken in docs

http://hongminhee.org/libsass-python/changes.html#version-0-7-0

Click '3.1.0'

Support indented syntax for string input

libsass supports the indented syntax, e.g.,

p
  a
    color: blue

This binding correctly handles files written in the indented syntax if passed as filenames with the .sass extension, e.g.,

sass.compile(filename="foobar.sass")

... but has no support for the indented syntax as string input, e.g.,

sass.compile(string="p\n  a\n    color: blue\n")

Perhaps a keyword parameter, e.g., syntax="sass" / syntax="scss"?

Unable to install libsass using pip on Mac OS X

Here is the log from a new Mac OS X 10.9.2 install with latest Xcode 5.1.

Bootstrap sass error

Libsass had error on if statement reported on bootstrap sass project.

This error has already been fixed, node-sass in version 0.8.6 handle bootstrap sass.

When I try compile bootstrap sass on libsass-python v 0.4.0 I am receiving:
error: non-terminal statement or declaration must end with ';'

segfault on ctrl-c

Reproduction: ctrl-c during our build

Custom functions?

Is it possible to add custom functions or provide a custom evaluation context as in the ruby version?
http://sass-lang.com/documentation/Sass/Script/Functions.html#adding_custom_functions

I need to inject some variables when I compile my scss.

libsass-python pulls different versions of libsass?

I use this excellent library as part of a build pipeline that ends with fingerprinting of my final minified css file. Yesterday (as I was preparing and then launched my site) I encountered an extremely frustrating bug.

In my requirements.txt file I have libsass==0.7.0. One of my servers was brought up a few weeks ago and everything worked great. In anticipation of high load I brought up a second server just before launch. The launch went off without a hitch except that sometimes the page would render with no CSS when you hit one of the servers; I traced this back to a different fingerprint on my css file. After verifying the python-libsass versions I ran the build process on each server individually and saw that my file outputs differed by a single line (the @charset declaration if you're interested). After looking at various things such as my locale I was able to fix the issue on both servers by running pip uninstall libsass and then pip install libsass==0.7.0.

To say this was annoying to track down would be an understatement. I don't think that something like this should be even possible with the same version of the python bindings but I'm not familiar enough with C extension packaging to suggest a fix. Thanks for reading and great library!

Keep emitting source map on save in watch mode

This is quite useful feature whom develops heavy in devtools.

Currently, these command line options:

$ sassc [inputfile] [outputfile] -w -m

nor

$ sassc [inputfile] [outputfile] -wm

don't emit source map.

I (also) think it is libsass 2.0's problem. if someone faced problems like this, he must wait for supporting next libsass version.

I cannot build libsass on Mac OSX 10.7 (Lion)

I get this error while trying to build libsass via pip on Mac OSX 10.7.

cc1: error: -Werror=unused-command-line-argument-hard-error-in-future: No option -Wunused-command-line-argument-hard-error-in-future

It looks like its a flag only supported by newer versions of GCC, and OSX 10.7 is stuck with GCC 1.2 via XCode and friends. Do you know of some way around this?
