CPP2 language module has issues with block comments

[NiklasHeneka]

It seems the grammar from the cpp2 language module has problems parsing block comments containing code.

When running JPlag with the cpp2 language module, files containing block comments with code were skipped even though they were valid CPP code that can be executed since they are just comments.

Here is one of the skipped CPP files:

#include <iostream>

/*struct Dijete
{
    std::string ime;
    Dijete *sljedeci;
}

void Razvrstavanje(std::vector<std::string> &s, int k)
{

    Dijete *pocetak(nullptr), *prethodni;
    for(int i(0); i<s.size(); i++)
    {
        Dijete *novi(new Dijete);
        novi->ime=s[i];
        novi->sljedeci=nullptr;
        if(!pocetak) pocetak=novi;
        else prethodni->sljedeci=novi;
        prethodni=novi;

    }

}*/

int main ()
{
    return 0;
}

Building the current develop branch and running the cli with the cpp2 language module using the given example yields the following:

2023-08-11-09:58:44_817 [ERROR] SubmissionSet - ERROR -> Submission example.cpp removed

So it seems like the file is only ignored because it doesn't contain enough code to produce >=12 tokens. Also running with -t 4 makes it a valid submission for me.

Yes you are right. When I was running a data set I received two parsing errors and JPlag told me it skipped two files. I assumed these were the same files. But JPlag just skipped them because it doesn't contain enough code to produce >=12 tokens. The files with the parsing errors were completely different files.
