@sidvishnoi thank you for this PR...

Except for the fact that you inserted the TidyAttr_LOADING alphabetically, in tidyenum.h, it looks good...

I know the present docs says Please try to keep this enumeration in alphabetical order., but doing that would mean bumping the SOVERSION number for every change. See #851, and the many mentions of this in other comments here...

But no problem, this can be dealt with at the time of the merge, if I've got all the facts straight...

Again, thank you for the PR... will try to get to it soonest...
