lualatex assumes a writeable font cache relative to `$HOME`, for nix this has two implications.
First, the cache might diverge from the nix store if users use LuaLaTeX.
Second, `$HOME` needs to be set to a writable path in derivations.
It is fine to use `with` on the inputs, since that increases the
overall readability of the package.
Removes `wheel` from `nativeBuildInputs`, since it is a result of
cargo culting from an earlier setuptools example, that was wrong, and
it is not required, since it is provided by setuptools itself.
The python-updates branch was formerly called python-unstable, but the
new branch name was never mentioned in the docs. This commit changes the
branch name in the docs to python-updates.
We get a dependency list with pub2nix now. We can no longer easily distinguish between development dependency dependencies and regular dependency dependencies, but we weren't doing this anyway.
Without this, it's impossible to override the lockFile as the default
overrideAttrs is applied after the composition in buildNimPackage has
read the lock file and generated the nim flags from it.
We keep running into situations where we can't get the right
combination of rustc flags through build systems into rustc.
RUSTFLAGS is the only variable supported across build systems, but if
RUSTFLAGS is set, Cargo will ignore all other ways of specifying rustc
flags, including the target-specific ones, which we need to make
dynamic musl builds work. (This is why pkgsCross.musl64.crosvm is
currently broken — it works if you unset separateDebugInfo, which
causes RUSTFLAGS not to be set.)
So, we need to do the same thing we do for C and C++ compilers, and
add a compiler wrapper so we can inject the flags we need, regardless
of the build system.
Currently the wrapper only supports a single mechanism for injecting
flags — the NIX_RUSTFLAGS environment variable. As time goes on,
we'll probably want to add additional features, like target-specific
environment variables.
While the word 'simply' is usually added to encourage readers, it often has the
opposite effect and may even appear condescending, especially when the reader
runs into trouble trying to apply the suggestions from the documentation. It is
almost always an improvement to simply drop the word from the sentence.
(there are more possible improvements like this, we can apply those in separate
PRs)
Replaced with python3Packages except for the following to avoid misuse of pythonPackages
1. which we need for the explanation
2. which are replaced by python3Packages as variables
