A gdb-like debugger for nodejs. It is in the style of the trepanning debuggers.

var should = require('chai').should(),

    it('if (condition...) { ... } => condition;', function() {
	extract_expression('if (condition(x)) { return null };').should.equal('condition(x)');
	extract_expression('if (true) {').should.equal('true');
    });

    it('"while (expression) {" => expression', function() {
	extract_expression('while (expression) {').should.equal('expression');
    });

    it('"return return_value) {" => return_value', function() {
	extract_expression('return return_value').should.equal('return_value');
    });

    it('"nothing_done" => nothing_done', function() {

    });
