@fzakaria:one.ems.hostfzakariaI was looking today at https://github.com/jart/json.cpp -- vs nlohman20:23:42
@emilazy:matrix.orgemily the JSON library is extremely load-bearing for evaluation semantics, please don't switch it out without a very thorough test suite and fuzzing; the switch to nlohmann_json in 2.4 already produced a lot of eval changes 20:30:05
@fzakaria:one.ems.hostfzakariaJust sharing it; I sponsor jart via GitHub (I wish a larger amount) so I try to follow up on the work she does. -- I really like all the work she does + I find her code outstanding.20:32:43
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)Also let's first handle the TOML fiasco20:40:26
@emilazy:matrix.orgemilyI did my best :D20:41:03
@fzakaria:one.ems.hostfzakariawas that solvable ? I thought it's just not because of the spec20:41:06
@emilazy:matrix.orgemilyit was solved by fixing the TOML spec violation in Nixpkgs20:41:30
@emilazy:matrix.orgemily(that 2.3 already barfed on, and that was present when 2.3 was still minver, so it was just unambiguously a bug)20:41:45
@fzakaria:one.ems.hostfzakariais boost supposed to be a pkg-config?21:05:38
@fzakaria:one.ems.hostfzakaria

i'm surprised i am missing it when trying to use Nix as a library

ix/store/dxar61b2ig87cfdvsylfcnyz6ajls91v-nix-2.28.3-dev/include/nix/util/fmt.hh:4:10: fatal error: boost/format.hpp: No such file or directory
    4 | #include <boost/format.hpp>
      |          ^~~~~~~~~~~~~~~~~~

21:05:50
@fzakaria:one.ems.hostfzakariaI would have thought Nix .pc files should declare all their dependencies or something21:06:17
@fzakaria:one.ems.hostfzakaria I add boost as a buildInput and it's fixed but .. feels wrong 21:07:04
@emilazy:matrix.orgemily no, Boost does not support pkg-config 21:09:42
