RE: [Jython-users] Accessing Jython Regular Expressions from java

[Guy Gascoigne-P. <gg...@tr...>]

Wow, that opens up a whole avenue of ways to integrate jython and java that
I'd never realized.  Thanks for the example; it makes things a whole lot
clearer.

Guy - who still can't believe just how cool jython is :-)

No, that is not quite what I said. I meant that sre only works in a
jython environment.

A java class like this below can imported from jython and can make use
of all the other jython modules, classes and functions. 

import org.python.core.*;

public class y {
    public static void test() {
        // import re
        PyObject re = __builtin__.__import__("re");

        // res = re.match(r"(source filename|Name of).*\?(?i)", 
                          "nAME OF ?")
        PyObject res = re.invoke("match",
            Py.java2py("(source filename|Name of).*\\?(?i)"),
            Py.java2py("nAME OF ?"));

        // print res.group(1)
        System.out.println(res.invoke("group", Py.newInteger(1)));
    }
}


Jython 2.1+ on java1.4.0-beta3 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> import y
>>> y.test()
nAME OF
