Bindings for libsass
Installation
Mac: brew install libsass
Linux: I'm working on instructions
Add this to your application's shard.yml:
dependencies:
crass:
github: vonkingsley/crass
Usage
require "crass"
Start with creating some options or use the defaults
opts = Crass::Options.configure do |conf|
conf.precision = 8
conf.linefeed = "\n\n"
end
Or
opts = {:precision => 4, :input_file => "/home/user/borders.scss"}
Or
opts = Crass::Options.new
opts.precision = 8
opts.output_style = Crass::SassOutputStyle::COMPRESSED
Options:
{
:precision => Int32,
:output_style => Crass::SassOutputStyle,
:source_comments => Bool,
:source_map_embed => Bool,
:source_map_contents => Bool,
:omit_source_map_url => Bool,
:is_indented_syntax_src => Bool,
:indent => String,
:linefeed => String,
:input_path => String,
:output_path => String,
:plugin_path => String,
:include_path => String,
:source_map_file => String,
:source_map_root => String
}
Create a Context
[Data]
ctx = Crass::Context::Data.new("$five: 5px;\n#main{margin: $five;}", opts)
output = ctx.compile #=> output css
puts output
rescue e : Crass::SassError
puts e.message
ensure
#free the context when you are done, please.
ctx.delete if ctx
[File]
ctx = Crass::Context::File.new("/home/user/margins.scss", opts)
output = ctx.compile #=> output css
puts output
rescue e: Crass::SassError
puts e.message
ensure
#free the context when you are done, please.
ctx.delete if ctx
You can also create a file context with the default options with just a File object or filename
ctx = Crass::Context::File("/home/user/index.scss")
Or
my_sass = File.new("/home/user/padding.scss")
ctx = Crass::Context::File(my_sass)
Compiler
You may want more control and timing of the compile process.
Create a context and get the compiler
ctx = Crass::Context::File.new("/home/user/home.scss", opts)
compiler = ctx.compiler
compiler.parse
puts compiler.state
compiler.execute
puts compiler.state
ctx.output
Command line
You can use the above library within your code or the command line to convert your files or directories
crystal build src/crass.cr
crass -h
If you have original style sass and want scss output you can build my version of the sass2scss tool
crystal build src/sass2scss.cr
sass2scss -h
TODO
[ ] Sass Values
[ ] Sass Function
[ ] Sass Importer
[ ] A lot more error control
