Implement copy and paste code / text?

Question

I have a bunch of old javascript files that look very similar. I would like to implement a copied / pasted code detection tool, but I could not find the description of the algorithm ... I am already using a sonar with the javascript plugin to detect such code, but I would like to have finer control over the detection ...

Is there any "standard" algorithm for this problem? Is there a library to perform this analysis (python or java ...)?

thanks.

You can take a look at CloneDigger , it is designed to detect clones in python or java code, but the algorithm is described here .
