Now it's possible to use in an overlay `guiSupport` set to `false`
(boolean) and doing so will disable many X related dependencies from
being used and the closure would be reduced automatically - Close#116716.

pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
In the current Vim, the Python support can be implemented by linking to
the Python library, e.g., lib/libpython3.8.dylib on darwin. The
previous workaround of wrapping Vim to prefix $PATH is not sufficient
anymore. Since in the current Vim, the Python interpreter is no longer
invoked, but instead, the dynamically linked library is used, in which
only the original Python modules are loaded, causing plugins to fail
to load their required Python modules.
Experiments show that, however, it is controlled by the $NIX_PYTHONPATH
environment variable. In this commit, we add the required environment
variable to the wrapped Vim workaround as previously proposed. So that
the Vim plugins can use Python modules in the specified Python derivation.
Whenever we create scripts that are installed to $out, we must use runtimeShell
in order to get the shell that can be executed on the machine we create the
package for. This is relevant for cross-compiling. The only use case for
stdenv.shell are scripts that are executed as part of the build system.
Usages in checkPhase are borderline however to decrease the likelyhood
of people copying the wrong examples, I decided to use runtimeShell as well.
Using gtk + darwin support seems broken at the moment, we probably want
guiSupport = "carbon" instead but that doesn't work and something like
macvim is probably better for that. This fixes the build while keeping
guiSupport enabled which might be desirable for eg. +clientserver.
Fixes#45025
As suggested by @jtojnar in GitHub issue #44580, this patch adds the
package `wrapGAppsHook` to the dependencies (specifically, the
`nativeBuildInputs`) of `vim_configurable`, when `vim_configurable` is
built against GTK 3.
This change prevents GVim from crashing if one tries to use its
file-choosing dialog, and fixes a warning that otherwise might be
emitted if one tries to use its find/replace dialog.
Use `stdenv.mkDerivation` directly instead of `composableDerivation`.
Some configure flags may have changed as the conversion wasn't exactly
straightforward.
It seems as Python will be fetched from $PATH in Vim 8.1:
```
stat("/home/ma27/bin/python", 0x7ffe57a317b0) = -1 ENOENT (No such file or directory)
stat("/run/wrappers/bin/python", 0x7ffe57a317b0) = -1 ENOENT (No such file or directory)
stat("/home/ma27/.nix-profile/bin/python", 0x7ffe57a317b0) = -1 ENOENT (No such file or directory)
stat("/nix/var/nix/profiles/default/bin/python", 0x7ffe57a317b0) = -1 ENOENT (No such file or directory)
stat("/run/current-system/sw/bin/python", {st_mode=S_IFREG|0555, st_size=291, ...}) = 0
readlink("/run/current-system/sw/bin/python", "/nix/store/ggjkqbvwnv7dflkmdgmmp"..., 4096) = 72
```
This breaks in cases where you want to use a modified Python derivation
for the VIM plugins you use in `vim_configurable`:
```
let
vim_configurable' = vim_configurable.override {
# python with modules for ensime
python = python.withPackages (ps: with ps; [ sexpdata websocket_client ]);
};
in
vim_configurable'.customize {
# ...
}
```
With VIM 8.0 this worked perfectly fine, now it's necessary to install
the modified `python` in $PATH to actually use it, otherwise an error
like this arises:
```
[ensime] A dependency is missing, please `pip2 install sexpdata websocket-client` and restart Vim.
Press ENTER or type command to continue
```
However it should be possible to pass the modified Python to the
modules, the easiest workaround is to write a wrapper which prefixes
$PATH to have the Python derivation available.
This doesn't change any defaults; I suspect that dropping gtk2 support
would annoy some people so I didn't want to do that without asking
around first.
- fix wrongly used *native* build inputs;
- remove confusing `prePatch = "cd src";` ;
- adapt RPATH handling to multiple-output changes;
- don't list full compiler flags in vim --version,
as that would keep references to -dev paths.
Together, the closure of the default feature-set drops almost by 100 MB.
The lean vim attribute would *not* lose any references due to patching
--version, so we only apply it for vim_configurable.
In the [discussion](https://github.com/NixOS/nixpkgs/pull/18801) of this pull
request @LnL7 was unable to complete a darwin build because the
python_framework.patch does not apply and suggests it should be removed.
Instead of explicitly stating "I want version 3" or "I want version 2"
you now simply specify what the python argument will be, and
vim_configurable will set up the flags for you. config.vim.python must
be set, still.
