Clojure wrapper for a SPARQL 1.1 parser written in Javascript, using an embedded V8 interpreter

= Dependencies

• V8 Javascript engine, instructions to build and install can be found here: http://code.google.com/apis/v8/build.html

• A sample building command for OSX 64 bits generating a static lib is:

  v8-read-only $ scons mode=release library=static snapshot=on arch=x64

= Building & running

1) Build C++ dynamic lib

sparql-clj-v8-integration$ export CPLUS_INCLUDE_PATH=/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Headers/ sparql-clj-v8-integration$ make

2) Build Java JNI wrapper

sparql-clj-v8-integration$ cd java sparql-clj-v8-integration/java$ javac sparqltest/SparqlParser.java sparql-clj-v8-integration/java$ jar cf SparqlParser.jar sparqltest/SparqlParser.class

3) Set up Clojure project

sparql-clj-v8-integration/java$ cd ../clj-sparql-test sparql-clj-v8-integration/clj-sparql-test$ lein deps sparql-clj-v8-integration/clj-sparql-test$ cp ../js/sparql_parser.js . sparql-clj-v8-integration/clj-sparql-test$ cp ../java/SparqlParser.jar ./lib/ sparql-clj-v8-integration/clj-sparql-test$ cp ./libSparqlParserWrapper.dylib .

4) Test the library from Slime

sparql-clj-v8-integration/clj-sparql-test$ lein swank
