GrB_get instead of fprint

[rayegun]

Could an option be added to GrB_get the equivalent of GxB_fprint for all objects as a string? I may make a PR if I get some time.

That would be possible. I assume there would be a need to specify the amount of details in the string, like my GxB_Print_Level enum, as well.

There's no way to log a function to print a user-defined type. That's a separate but related issue ( #143 )
