Quoting from the splitString docstring:
NOTE: this function is not performant and should never be used.
This replaces trivial uses of splitString for splitting version
strings with the (potentially builtin) splitVersion.
This removes the unnecessary compiler build dependency. We also set
preferLocalBuild = true;
allowSubstitutes = false;
to not farm out the build on a remote builder or bother with trying to
find a binary substitution.
The architecture of an image should default to the architecture for
which that image is being composed or pulled. buildPackages.go.GOARCH is
an easy way to compute that architecture with the correct terminology.
These should not cause issues in practice but it is good idea to handle them.
* prefix and targetOffset are mandatory, as they are always set by the generic builder.
* wrapPrefixVariables and dontWrapGApps are now defaulting to empty value, as they are not mandatory.
Before this change, buildRustCrate always called rustc with
--extern libName=[...]libName[...]
However, Cargo permits using a different name under which a dependency
is known to a crate. For example, rand 0.7.0 uses:
[dependencies]
getrandom_package = { version = "0.1.1", package = "getrandom", optional = true }
Which introduces the getrandom dependency such that it is known as
getrandom_package to the rand crate. In this case, the correct extern
flag is of the form
--extern getrandom_package=[...]getrandom[...]
which is currently not supported. In order to support such cases, this
change introduces a crateRenames argument to buildRustCrate. This
argument is an attribute set of dependencies that should be renamed. In
this case, crateRenames would be:
{
"getrandom" = "getrandom_package";
}
The extern options are then built such that if the libName occurs as
an attribute in this set, it value will be used as the local
name. Otherwise libName will be used as before.
luarocks defines by default the following mirrors:
83093e7da7/src/luarocks/core/cfg.lua (L205)
Let's add them to nixpkgs. I have modified luarocks-nix to generate the
proper nixpkgs urls.
I bump luarocks-nix in the following commits.
This is a new package that provides a shell hook to make it easy to
declare manpages and shell completions in a manner that doesn't require
remembering where to actually install them. Basic usage looks like
{ stdenv, installShellFiles, ... }:
stdenv.mkDerivation {
# ...
nativeBuildInputs = [ installShellFiles ];
postInstall = ''
installManPage doc/foobar.1
installShellCompletion --bash share/completions/foobar.bash
installShellCompletion --fish share/completions/foobar.fish
installShellCompletion --zsh share/completions/_foobar
'';
# ...
}
See source comments for more details on the functions.
applyPatches applies a list of patches to a source directory.
For example to patch nixpkgs you can use:
applyPatches {
src = pkgs.path;
patches = [
(pkgs.fetchpatch {
url = "1f770d2055.patch";
sha256 = "1nlzx171y3r3jbk0qhvnl711kmdk57jlq4na8f8bs8wz2pbffymr";
})
];
}
There ver very many conflicts, basically all due to
name -> pname+version. Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job. There might be some fallback to these
conflicts, but I believe it should be minimal.

They always can be regenerated during the actual build, and they are sometimes
random, e.g in Tensorflow;
