You might be able to do something with cloc and a shell script for a rough
estimate.
```
$ cd ghc
$ nix-shell -p clock --run "cloc ."
```
will output a detailed report of the loc and language breakdown of the top
level ghc directory (it is comment-aware and aware of many languages).
there might be a way to get cloc or a similar tool to output something more
inspect able (eg json), and then use a shell script to gather everything
from the appropriate directories/files.
I suspect something could be hacked up in less than a day, but it would
require a bit of research. Hopefully this is helpful and gets you going -
I'd be happy to hear of better solutions.
Thanks

Dear GHC devs
Is it possible to get a "lines-of-code" summary of GHC these days? Like the one below, from 2011.
It needs more than `wc` because it's helpful to split lines of code from lines of comments and notes.
We used to have `count_lines` but I'm not sure whether it is still extant.
I'm giving a talk at Zurihac on Sunday morning, about the internals of GHC. Any data before then, preferably in a form comparable to that below, would be terrific.
But you have a lot else to do. This isn't do-or-die, just nice to have.
Thanks
Simon
