Avoids confusion: `vim-full`'s build-time features are configurable, but both
`vim` and `vim-full` are *customizable* (in the sense of user configuration).
`makeCustomizable` can be called on vim derivations that don't depend on
python, so avoid including python3 in the environment if there are no python3
dependencies.

Basically it was hard to install both
nvim-treesitter.withPlugins (
plugins: with plugins; [
tree-sitter-c
tree-sitter-lua
tree-sitter-org-nvim
]
));
and nvim-treesitter
It also simplifies some nix code.
Adding "packages" to the neovim distribution triggers the wrapping of
the derivation. This is because it tries to "set packpath/rtp" in the
init.vim.
If we set these arguments via --cmd instead we can avoid to create an
init.vim, which can be useful if we want to wrap an init.lua later on
(in home-manager for instance, we dont want to generate viml code).
Also removes the support for "configure" in makeNeovimConfig and
configure.plug / configure.vam packages in the compatibility layer
'legacyWrapper'.
Neovim plugins are now more often than not written in lua.
One advantage of the lua ecosystem over vim's is the existence of
luarocks and the rockspec format, which allows to specify a package
dependencies formally.
I would like more neovim plugins to have a formal description,
"rockspec" being the current candidate.
This MR allows to use nix lua packages as neovim plugins, so as to enjoy
every benefit that rockspecs bring:
- dependdency discovery
- ability to run test suite
- luarocks versioning
- rockspec metadata
the vim update.py script will check if an attribute with the vim plugin
pname exists in lua51Packages. If it does, it uses
buildNeovimPluginFrom2Nix on it, which modifies the luarocks config to
do an almost flat install (luarocks will install the package in the lua
folder instead of share/5.1/lua etc).
It also calls toVimPlugin on it to get all the vim plugin niceties.
The list of packages that could benefit from this is available at
https://luarocks.org/labels/neovim
but I hope it grows.
I've been working for a long time towards automatic nix dependencies for
neovim plugins (using luarocks rockspecs to discover the said
dependencies).
This is an initial commit to help me complete the missing bits.
buildNeovimPluginFrom2Nix is right now a placeholder which helps me test
in my fork a version that does a flat install of luarocks.
the vim updater will now check for attributes with the same name in the lua package set,
if that's the case the script will generate buildNeovimPluginFrom2Nix.
The current wrapper only includes vim, gvim and the man pages
(optionally). This rewrite distinguishes two scenarios, which I expect
cover the majority of use cases:
- standalone mode, when `name != "vim"`, means the user already has a
vim in scope and only wants to add a customized version with a
different name. In this case we only include wrappers for `/bin/*vim`.
- non-standalone mode, when `name == "vim"`, means the user expects a
normal vim package that uses the specified configuration. In this case
we include everything in the original derivation, with wrappers for
all the executables that accept a vimrc.
