Period in username not "escaped"

[horriblename]

on my work laptop my username is "firstname.lastname" and running nh home switch . gives this error:

'...' does not provide attribute 'packages.x86_64-darwin.homeConfigurations.firstname.lastname.config.home.activationPackage', 'legacyPackages.x86_64-darwin.homeConfigurations.firstname.lastname.config.home.activationPackage' or 'homeConfigurations.firstname.lastname.config.home.activationPackage'

-c firstname.lastname doesn't help either

Could paste the output with --verbose?

for reference, home-manager switch --flake firstname.lastname worked fine

it seems we need to handle the dot to pass it properly to nix build

This line
https://github.com/viperML/nh/blob/master/src/home.rs#L59

            "{}#homeConfigurations.{}.config.home.activationPackage",

should be changed to

            "{}#homeConfigurations.\"{}\".config.home.activationPackage",

that won't effect anyone who doesn't have a .

This line is for nixos, could be useful there too, it doesn't harm.

I'm curious about how @horriblename deals with this on a daily basis, as apparently shells like bash and fish interpret the quotes.

Dumping the received argv[1] shows the following:

$ gcc -Wall ./main.c -o main

$ ./main .#foo."a.b".baz
|.|#|f|o|o|.|a|.|b|.|b|a|z

$ ./main .#foo.\"a.b\".baz
|.|#|f|o|o|.|"|a|.|b|"|.|b|a|z

HM adds the escaped quotes here: https://github.com/nix-community/home-manager/blob/afd2021bedff2de92dfce0e257a3d03ae65c603d/home-manager/home-manager#L213

I don't recall ever needing to type literal " in the shell luckily 😀 but \" is probably what I'd do as well
