Hi. Nix language has a built-in function builtins.listToAttrs which
converts list to the Attrs. I'm searching a way to make an opposite
thing - convert attrs to a list. Say, I'd like to convert
users = {
root = { name = root; group = groups.root; };
ssh = { name = ssh ; group = groups.nogroup ; severity = 33; };
};
to a list like this:
[
{ name = root; group = groups.root; }
{ name = ssh ; group = groups.nogroup ; severity = 33; }
];
to use it later both in shell scripting, as list
lib.map (toList users) (u: ''
adduser ${u.name} ${u.group}
'');
.. and in derivations, by reference
stdenv.mkDerivation ssh {
user = users.ssh;
};
In order to workaround the problem I have to add additional field
`list' (like below) but this way I have to duplicate field names which
is not good (easy to forget). So Is it possible to do the
transformation in a more
safe way?
Regards,
Sergey
# A workaround
users = rec {
root = { name = root; group = groups.root; };
ssh = { name = ssh ; group = groups.nogroup ; severity = 33; };
list = [ root ssh ];
};
