Julia line number included in error messages

If an exception is raised that contains Julia line number information, that line number information is inserted into the Javascript exception.

Module qualified function names

Support has been added for qualifying function by the module name. For example the BLAS function dot can be invoked directly through the BLAS module using the following.

var a = new Float64Array(2);
var b = new Float64Array(2);

a[0] = 1.0;
a[1] = 2.0;
b[0] = 3.0;
b[1] = 4.0;

res = julia.exec('Base.LinAlg.BLAS.dot',a,b);
