/* See https://github.com/NixOS/nix/issues/749. Eventually we'd like these
|
||||||
|
to expand to Nix builtins that carry metadata so that Nix can filter out
|
||||||
|
the INFO messages without parsing the message string.
|
||||||
|
|
||||||
|
Usage:
|
||||||
|
{
|
||||||
|
foo = lib.warn "foo is deprecated" oldFoo;
|
||||||
|
}
|
||||||
|
|
||||||
|
TODO: figure out a clever way to integrate location information from
|
||||||
|
something like __unsafeGetAttrPos.
