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.
