OSSP js is a stand-alone distribution of the JavaScript (JS) programming language reference implementation from Mozilla -- aka "JSRef" or "SpiderMonkey". This distribution provides a smart, stand-alone and portable distribution of Mozilla JavaScript through a GNU autotools-based build environment. Additionally, the C API in "libjs" contains both the JavaScript engine and the required Sun math library ("fdlibm") and with all internal symbols carefully protected under the "js" namespace. Finally, a js-config(1) utility and a pkg-config(1) specification is provided to allow applications to easily build with the JavaScript C API. OSSP js was created because for OSSP and similar pedantic C coding projects a smart, stand-alone, portable, clean, powerful and robust scripting language engine is required. JavaScript is a great programming language and Mozilla JavaScript "SpiderMonkey" definitely is an acceptable clean, powerful and robust implementation. Unfortunately there is just a stand-alone distribution released from time to time by Mozilla and it is far away from really being smart, stand-alone and portable. OSSP js combines the best from two worlds: the 1:1 repackaged JavaScript code base from Mozilla with the GNU autotools-based build environment as always used by OSSP. Additionally, this package provides stdio-based file object support and does not depend upon the Mozilla NSPR library.
