can not getInstrumenter when write my own custom middleware

[flyHe]

I write my own custom middleware.As in:

var im = require('istanbul-middleware'),
app.use(function (req, res, next) {
    if (isJSRequiringCoverage(req)) {
        var file = getFilePath(req), //it's ok
            code = readTheCodeFromFile(file),//it's ok
            instrumenter = im.getInstrumenter(); //TypeError: im.getInstrumenter is not a function
        res.send(instrumenter.instrumentSync(code, file));
            //exception handling omitted for brevity
    } else {
        next();
    }
});

the getInstrumenter function is defined in './core.js',I can not use it on im

[flyHe]

maybe the getInstrumenter should be exported in handlers.js

Alright,I do it by myself requiring './core.js'
