clangd broke because it can't look through symlinks. compile_commands manipulation does not fix it, clangd configuration does not fix it, a vfs overlay does not fix it, and while a combination of those can fix it with a bind mount in place that's just too cursed to even consider clangd bug: https://github.com/llvm/llvm-project/issues/116877 Change-Id: I8e3e8489548eb3a7aa65ac9d12a5ec8abf814aec

Download the specified URL, unpack it and return the path of the
unpacked tree. The file must be a tape archive (.tar) compressed
with gzip, bzip2 or xz. The top-level path component of the
files in the tarball is removed, so it is best if the tarball
contains a single directory at top level. The typical use of the
function is to obtain external Nix expression dependencies, such as
a particular version of Nixpkgs, e.g.
with import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/nixos-14.12.tar.gz") {};
stdenv.mkDerivation { … }
The fetched tarball is cached for a certain amount of time (1
hour by default) in ~/.cache/nix/tarballs/. You can change the
cache timeout either on the command line with --tarball-ttl
number-of-seconds or in the Nix configuration file by adding
the line tarball-ttl = number-of-seconds.
Note that when obtaining the hash with nix-prefetch-url the
option --unpack is required.
This function can also verify the contents against a hash. In that
case, the function takes a set instead of a URL. The set requires
the attribute url and the attribute sha256, e.g.
with import (fetchTarball {
url = "https://github.com/NixOS/nixpkgs/archive/nixos-14.12.tar.gz";
sha256 = "1jppksrfvbk5ypiqdz4cddxdl8z6zyzdb2srq8fcffr327ld5jj2";
}) {};
stdenv.mkDerivation { … }
