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

2. which are replaced by python3Packages as variables
* luarocks-packages-updater: init
Goal is to make it possible to maintain out-of-tree luarocks packages
without needing to clone nixpkgs.
maintainers/scripts/update-luarocks-packages gets renamed to
pkgs/development/lua-modules/updater/updater.py
Once merged you can run for instance
nix run nixpkgs#luarocks-packages-updater -- -i contrib/luarocks-packages.csv -o contrib/generated-packages.nix
I also set the parallelism (--proc) to 1 by default else luarocks fails
because of https://github.com/luarocks/luarocks/issues/1540
* Update maintainers/scripts/pluginupdate.py

* doc/stdenv: rewrite manual build procedure to be closer to an auto-build
This is based on
<https://jade.fyi/blog/building-nix-derivations-manually/> plus some
more original research.
The previous version of this section did not work for your choice of
simple Haskell package, e.g. haskellPackages.hscolour, due to things
like `compileBuildDriverPhase` and other custom phases that it
does not address at all.
It seems more correct to use genericBuild in development to harmonize it
with what is actually done.
I feel a little bit like I am committing a sin by suggesting using the
experimental CLI in the manual (afaict I am the first to do this), but I
have given the old version of the command, and there are justifiable
reasons to do it:
* The noted limitations with env-vars are fixed. The one with the
non-empty temp directory was one I ran into myself and oh boy was that
not fun to debug.
* Additionally the outputs are set *before* sourcing `setup.sh`: there
is an issue with nix-shell where the original version of `$out` winds
up in `NIX_LDFLAGS` due to _addRpathPrefix, which means that resulting
executables may not run properly.
It is sad that `nix develop` propagates a wrong value of `SHELL` to
builders, though. It is equally sad that `nix-shell` is essentially
abandoned upstream, with undocumented and not insignificant differences
from `nix develop`.
For the exact script differences:

I chose not to do nixos.{config, options} because that would make it
look too much like a configuration object, which it is not.
A configuration object I would define as for example the result of
calling NixOS, an attrset with `_type = "configuration";`.
Recreating a configuration object without evalModules is quite
feasible but not guaranteed to be correct, and not maintainable.
This commit adds minimal documentation of the supported platforms.
More exhaustive documentation would require producing a list of
platforms for each of the 7 tiers. This was attempted in #245368, but it
quickly became clear that that would be a long-term effort.
In the meantime, this commit adds the most important information to the
manual.

The nixpkgs documentation mentions how to update out of tree plugins but
one problem is that it requires a nixpkgs clone.
This makes it more convenient.
I've had the need to generate vim plugins and lua overlays for other
projects unrelated to nix and this will make updates easier (aka just
run `nix run nixpkgs#vimPluginsUpdater -- --proc=1` or with the legacy commands:
`nix-shell -p vimPluginsUpdater --run vim-plugins-updater`.
I added an optional "nixpkgs" argument to command line parser, which is the path
towards a nixpkgs checkout. By default the current folder.
