This is a small command-line utility to count lines in a file. That's it. That's all it does. Technically, it doesn't even care if it's text.
This is the .NET 6.0 + AVX2 version of my other .NET line counter.
There are some counting assumptions that I made. I had originally chosen to have this match my editor's line count. That is, if Visual Studio Code shows x lines then my logic would also show x lines. However, I've chosen to follow the behavior of wc -l. I count carriage returns (\n). If a file does not end with a carriage return then the last line will not be counted.
Clone this repository and then run dotnet build from the solution root.
> dotnet build -c Release --nologoThis will create a release build of the utility at /bin/Release/net6.0/nlc.exe. From there, you will need to copy it to a place in your %PATH%.
Unlike nlc, fnlc can only parse files.
To read a file:
> fnlc "path/to/your/file.txt"
The only output from fnlc will be the line count, or the error (errors are not written to STDERR)
So the full run might look like
> fnlc "path/to/your/file.txt"

I'd like to thank @buildstarted of linksfor.dev(s) fame for cracking the mystery of how to get a Vector256 into a Popcount. This approach wasn't worth it until we got that code.
