[J3] [EXTERNAL] Re: Why is += missing?

[Clune, Thomas L. (GSFC-6101)]

I’m pretty bad at nontrivial grep and completely foobar’d my earlier submission.   So I’ve turned to my “grep guy” for help.   Am now using:


$ rg -t fortran -P '^\s*([A-Za-z0-9_]+)\s*=\s*(?i)\1\s*\+'

This properly accounts for extra spaces, underscore characters and case insensitivity.

And for SLOC I’m now using  `scc –no-gitignore | grep -i fortran`:

Now I can do the entire weather model in one fell swoop:

SLOC:          2046k
+= use cases:  13447
%              0.66

But there is considerable variability among layers:

Repository      SLOC         A = A+       % use
MAPL             105k         487          0.5
GMAO_Shared      198k        3314          1.7
FMS               76k         712          0.9
NCEP_Shared       33k         499          1.5

So not overwhelming, but certainly would not be a rarely used feature.
