This commit splits the `buildPythonPackage` into multiple setup hooks.
Generally, Python packages are built from source to wheels using `setuptools`.
The wheels are then installed with `pip`. Tests were often called with
`python setup.py test` but this is less common nowadays. Most projects
now use a different entry point for running tests, typically `pytest`
or `nosetests`.
Since the wheel format was introduced more tools were built to generate these,
e.g. `flit`. Since PEP 517 is provisionally accepted, defining a build-system
independent format (`pyproject.toml`), `pip` can now use that format to
execute the correct build-system.
In the past I've added support for PEP 517 (`pyproject`) to the Python
builder, resulting in a now rather large builder. Furthermore, it was not possible
to reuse components elsewhere. Therefore, the builder is now split into multiple
setup hooks.
The `setuptoolsCheckHook` is included now by default but in time it should
be removed from `buildPythonPackage` to make it easier to use another hook
(curently one has to pass in `dontUseSetuptoolsCheck`).
This setup hook modifies a Perl script so that any "-I" flags in its shebang
line are rewritten into a "use lib ..." statement on the next line. This gets
around a limitation in Darwin, which will not properly handle a script whose
shebang line exceeds 511 characters.
This system type was previously broken but is now fixed.
Add it here to showcase the common task of launching a fully-fledged Android
system with an included app store.
The function buildGoModule builds Go programs managed with Go modules. It builds
a Go module through a two phase build:
- An intermediate fetcher derivation. This derivation will be used to
fetch all of the dependencies of the Go module.
- A final derivation will use the output of the intermediate derivation
to build the binaries and produce the final output.
Since Intel's default openmp implementation is available in the same src
tarball, we can just include it in the package. This means that `mkl` now "just
works" without any environment variables, fragile setup-hooks, or forced
propagation.
Since the openmp implementation is only needed at runtime (and for test cases),
users can substitute a different one if they prefer by exporting it with
`LD_PRELOAD`, which is how Intel recommends handling this. If they do not do so,
`libiomp.so` lives next to `libmkl_rt.so` and thus will be in the RPATH as a
sane default.
Since this still comes from the same src tarball, we can ship it without losing
the fixed-output derivation; likewise, since Hydra is not building or caching
these, shipping these proprietary packages costs no bandwidth for the nix
community.
Python 3.4 will receive it's final patch release in March 2019 and there won't
be any releases anymore after that, so also not during NixOS 2019.03.
Python 3.4 is not used anymore in Nixpkgs. In any case, migrating code from
3.4 to 3.4+ is trivial.
This commit renames the pythondaemon module to match its module name, github
name, and pypi name, which makes it easier to find and reference. In order to
avoid breaking any external users, I've left an alias with a deprecated warning.
The `name` arg of `vim_configurable.customize` does not only determine
the package name, but also the name of the command/ executable to be
called.
In my opinion this is not documented properly and finding that out took
me several hours.
This touches up a handful of places in the python documentation to try to make
the current best-practices more obvious. In particular, I often find the
function signatures (what to pass, what not to pass) confusing and have added
them to the docs.
Also updated the metas to be more consistent with the most frequently used
modern style.
A new python script has been added to replace the aged viml-based
updater. The new updater has the following advantages:
- use rss feeds to check for updates quicker
- parallel downloads & better caching
- uses proper override mechanism instead of text substitution
- update generated files in-place instead of having to insert updated plugins manually
Automatically reading `dependencies` from the plugins directory has been
not re-implemented.
This has been mostly been used by Mark Weber's plugins, which seem to
no longer receive regular updates.
This could be implemented in future as required.
Use example package `zerobin` instead of `bepasty-server` which
is no longer part of python-packages.
This fixes the examples for current nixpkgs versions.
1. Use the same approach like in the overlay example:
Override `python` instead of `pythonPackages` so that
`python.pkgs` refers to the new package set like `pythonPackages`.
This also fixes a bug in the original example where
`pkgs.fetchgit` was not in scope.
Add an extra example to illustrate how to override just a
package set.
2. Fix mix-up between `super` and `self` in the explanation text.
Also, simplify the explanation.
This fixes a regression introduced in 4b06383.

Relevant section: 9.5.2.3. How to install a compiler with libraries, hoogle and documentation indexes
Since version 5 `hoogle server`s --local flag solves the problem with links from
`http:` to `file:` URIs:
hoogle server --local -p 8080
Setting haskell.packageOverrides like so:
haskell = super.haskell // {
packageOverrides = self: super: {
my-package = ...;
my-other-package = ...;
};
};
causes all compiler-specific package sets to be overridden with those
overrides.
Nobody has stepped up to keep maintaining this and it's several
years old, and the last strict Java 7 dependency, as it won't work
with newer versions without an update.

Resolved the following conflicts (by carefully applying patches from the both
branches since the fork point):
pkgs/development/libraries/epoxy/default.nix
pkgs/development/libraries/gtk+/3.x.nix
pkgs/development/python-modules/asgiref/default.nix
pkgs/development/python-modules/daphne/default.nix
pkgs/os-specific/linux/systemd/default.nix
This involved:
* Installing miniperl as $dev/bin/perl
* Setting miniperl to take INC from
lib/perl5/{site_perl/,}cross_perl/${version} as well as
lib/perl5/{site_perl/,}/${version}/${runtimeArch}, in that
order. miniperl taking from runtimeArch is not really correct, but
it works in some pure-perl cases (e.g. Config.pm) and can be
overridden with the cross_perl variant.
* Installing perl-cross's stubs into
$dev/lib/perl5/cross_perl/${version}
* Patching MakeMaker.pm to gracefully degrade (very slightly) if B.pm
can't be loaded, which it can't in cross-compilation.
* Passing the right build-time and runtime perls to Makefile.PL
The biggest benefit is that we no longer have to update the registry
package. This means that just about any cargo package can be built by
nix. No longer does `cargo update` need to be feared because it will
update to packages newer then what is available in nixpkgs.
Instead of fetching the cargo registry this bundles all the source code
into a "vendor/" folder.
This also uses the new --frozen and --locked flags which is nice.
Currently cargo-vendor only provides binaries for Linux and
macOS 64-bit. This can be solved by building it for the other
architectures and uploading it somewhere (like the NixOS cache).
This also has the downside that it requires a change to everyone's deps
hash. And if the old one is used because it was cached it will fail to
build as it will attempt to use the old version. For this reason the
attribute has been renamed to `cargoSha256`.

1. Call `nix-build` with `--no-out-link` to avoid cluttering the source dir.
2. Re-add `patchShebangs`, since `buildCommand` doesn't imply a patch phase. (It was my fault to remove this in the first place, sorry!)
This allows one to always override the call to `buildPythonPackage`.
In the following example we create an environment where we have the `blaze` package using an older version of `pandas`. We override first the Python interpreter and pass `packageOverrides` which contains the overrides for packages in
the package set.
```
with import <nixpkgs> {};
(let
python = let
packageOverrides = self: super: {
pandas = super.pandas.overridePythonPackage(old: rec {
version = "0.19.1";
name = "pandas-${version}";
src = super.fetchPypi {
pname = "pandas";
inherit version;
sha256 = "08blshqj9zj1wyjhhw3kl2vas75vhhicvv72flvf1z3jvapgw295";
};
});
};
in pkgs.python3.override {inherit packageOverrides;};
in python.withPackages(ps: [ps.blaze])).env
```
1. 'wrapper' has been renamed to 'wrappedRuby', so use this instead.
2. mkDerivation isn't called with a 'src' attribute, so skip the 'unpackPhase' to avoid an error.
3. Simplify the build command. 'mkdir' and 'patchShebangs' don't need to be called explicitly.
Improve beam docs:
* correct spelling
* update per pandoc changes
* capitalize titles
* capitalize BEAM throughout and use "the BEAM" when referring to the virtual machine.

* reformat build-tools-rebar3 section
* add more links
* re-wrap <para>s
Also update <programlisting>s
* normalize whitespace
* don't double quote homepage
* use $ in all shell snippets
The documentation got a bit stale compared to actual contents of
nixpkgs. This commit focuses on updating existing docs, not on making
sure all details of beam packages are covered.
* Update python.md
this makes it clear how to alter `attributes` by using `packageOverrides`

If the flag enableIntegerSimple is true GHC will be build with the GPL-free but
slower integer-simple library instead of the faster but GPLed integer-gmp
library.
The attribute `pkgs.haskell.compiler.integer-simple."${ghcVersion}"` provides a
GHC compiler build with `integer-simple`.
Similarly, the attribute `pkgs.haskell.packages.integer-simple."${ghcVersion}"`
provides a package set supporting `integer-simple`.

This patch add a new argument to Nixpkgs default expression named "overlays".
By default, the value of the argument is either taken from the environment variable `NIXPKGS_OVERLAYS`,
or from the directory `~/.nixpkgs/overlays/`. If the environment variable does not name a valid directory
then this mechanism would fallback on the home directory. If the home directory does not exists it will
fallback on an empty list of overlays.
The overlays directory should contain the list of extra Nixpkgs stages which would be used to extend the
content of Nixpkgs, with additional set of packages. The overlays, i-e directory, files, symbolic links
are used in alphabetical order.
The simplest overlay which extends Nixpkgs with nothing looks like:
```nix
self: super: {
}
```
More refined overlays can use `super` as the basis for building new packages, and `self` as a way to query
the final result of the fix-point.
An example of overlay which extends Nixpkgs with a small set of packages can be found at:
https://github.com/nbp/nixpkgs-mozilla/blob/nixpkgs-overlay/moz-overlay.nix
To use this file, checkout the repository and add a symbolic link to
the `moz-overlay.nix` file in `~/.nixpkgs/overlays` directory.
I wanted to list the different texlive collections using the nix-repl, as per the [manual](https://nixos.org/nixpkgs/manual/#idm140737316065984).
It didn't work, since the nixpkgs were not loaded. Doing `:l <nixpkgs>` first resolved the problem.
This change adds the nixpkgs loading step to the manual so that the next inexperienced person don't have to figure out why it didn't work.
I tested this on NixOS unstable (16.09pre90254.6b20d5b) with nix-repl 1.11.3.
In #19309 a separate output for tkinter was added.
Several dependencies of Python depend indirectly on Python. We have the
following two paths:
```
‘python-2.7.12’ - ‘tk-8.6.6’ - ‘libXft-2.3.2’ - ‘libXrender-0.9.10’ -
‘libX11-1.6.4’ - ‘libxcb-1.12’ - ‘libxslt-1.1.29’- ‘libxml2-2.9.4’ -
‘python-2.7.12’
‘python-2.7.12’ - ‘tk-8.6.6’ - ‘libXft-2.3.2’ - ‘fontconfig-2.12.1’ -
‘dejavu-fonts-2.37’ - ‘fontforge-20160404’ - ‘python-2.7.12’
```
Because only `tkinter` needs this, I added
```
pythonSmall = python.override {x11Support = false;};
```
to break the infinite recursion. We also still have the output
`tkinter`.
However, we might as well build without x11Support by default. Then we build with x11Support as well so we get the tkinter module and put that in a separate package.
