Incorrectly recognizing Prolog code as Perl #84

Open andrewnicolalde opened 6 years ago

andrewnicolalde commented 6 years ago

Working on a project in Prolog, which happens to share the same .pl file extension as Perl. Seems CLOC get's it.

@andrewnicolalde I don't suppose you could create a sample repository to replicate this?

andrewnicolalde commented 5 years ago

Let me see what I can do :)

andrewnicolalde commented 5 years ago

As the repository is coursework and I'm not allowed to make it public, could I just add you as a contributor to the repo?

boyter commented 5 years ago

@andrewnicolalde That would work for me.

So I had a look. The reason for this is that loc does not support multiple file extensions. However some tools such as scc (which I am the author of, polyglot and cloc do, but they also do not get this right.

Most of the above assume that prolog files would have the extension p or pro. If you are able to supply a list of keywords that clearly identify a prolog file however I can add that into scc and I am use the polyglot author and cloc will do the same.
