As you may know, I have been working on polyglot for some time now. It is now the second-most popular ATS project on github⁰ and it has reached a state of relative maturity.

With that in mind, I would like to make a pitch for polyglot by proving the following:

• polyglot is the fastest code-counting tool available
• polyglot is the only fast tool that correctly disambiguates file extensions when they conflict

Ambiguous Extensions

Unfortunately, despite the many other source-counting tools tested, nearly every one fell victim to the same bug: they have no mechanism to distinguish languages that use the same file extension. These collisions do actually happen in practice; .v is used by Coq and Verilog.

polyglot, linguist, enry, and cloc were the only tools to correctly handle this issue.

Performance

Our first benchmark is against the rust source repo.

Second, we look at the go source repo:

Third, the Linux source tree:

Finally, the OpenBLAS source tree:

As you can see, polyglot is the fastest tool. Moreover, it beats cloc, enry, and linguist by an order of magnitude and thus it is by far the fastest tool with any claim of correctness.
