Is there something like [scc](https://github.com/boyter/scc) that allows to determine some code metrics for Julia in an easy, fire-and-forget kind of manner? What I’d be interested in is a tool that I can point at a directory, which it will recursively crawl for Julia files and break the line counts down to something like

- # blank lines
- # comment lines
- # docstring lines
- # code lines
- # total lines

Of course, it would be interesting to also learn about things like number of docstrings, number of function/macro definitions etc. but that would just be the cherry on top 🙂

Side note: `scc` seems to [support Julia](https://github.com/boyter/scc/blame/master/LANGUAGES.md#L116).

They could probably use some improvements, though — their [Julia code-complexity patterns](https://github.com/boyter/scc/blob/61304326e1d6a6dcfe0cd29d1a3e86d0403a3b0d/languages.json#L3185-L3222) include a `switch` statement that doesn’t exist and omit a lot of operators, for example.

I made a little experience and a `&&` increases 2 complexity points whilst `&` increases 1!!!

Thanks for pointing this out! There are also more projects out there that support Julia, e.g., [tokei](https://github.com/XAMPPRocky/tokei). I was just wondering if there exists something similar in pure Julia that would allow to also get more Julia-specific information.

@sloede I had a look into this topic and tokei doesn’t look to report complexity. Did you try scc? A limitation I see is that it doesn’t report complexity by function. thanks

Yes, I’ve been using scc for the time being.
