    SWIG

    SWIG

    A code generator for connecting C/C++ with other programming languages

    SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is used with different types of target languages including common scripting languages such as Javascript, Perl, PHP, Python, Tcl and Ruby. The list of supported languages also includes non-scripting languages such as C#, D, Go language, Java, Lua, OCaml, Octave, R and Scilab. Also several interpreted and compiled Scheme implementations (Guile, MzScheme/Racket) are supported. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG is typically used to parse C/C++ interfaces and generate the 'glue code' required for the above target languages to call into the C/C++ code. SWIG can also export its parse tree in the form of XML.

    node-sass

    node-sass

    Node.js bindings to libsass

    Node-sass is a library that provides binding for Node.js to LibSass, the C version of the popular stylesheet preprocessor, Sass. It allows you to natively compile .scss files to css at incredible speed and automatically via a connect middleware. A custom importer allows extension of the LibSass engine in both a synchronous and asynchronous manner. In both cases, the goal is to either return or call done() with an object literal. When returning or calling done() with { file: "String" }, the new file path will be assumed for the @import. It's recommended to be mindful of the value of prev in instances where relative path resolution may be required. When returning or calling done() with { contents: "String" }, the string value will be used as if the file was read in through an external source.
