Eschwartz [1] filed a deletion request for nlohmann_json-git [2]: This and nlohmann-json-git are duplicates, even though this was uploaded first the name sucks and so does the PKGBUILD, so the other one should be kept. This would keep consistency with the non-git package, for starters. [1] https://aur.archlinux.org/account/Eschwartz/ [2] https://aur.archlinux.org/pkgbase/nlohmann_json-git/
