Plugins from luarocks (e.g. telescope-nvim) have dependencies specified
in propagatedBuildInputs. These dependencies are not added as plugins in
Nvim runtime. They are added to LUA_PATH env var for wrapped neovim.
This commit collects all propagatedBuildInputs from input plugin list
and puts them in the combined plugin.
Note that such dependencies are never combined, because they are not
plugins.
During the last half of the year many dependencies of plugins used in
the tests were changed in nixpkgs. To make tests more robust use a
specially crafted stub plugins.
This reverts commit bb5b0a2655.
This change defeats the purpose of the dependency test. Revert it.
The test should verify that dependencies are correctly pulled. If
upstream plugin doesn't have dependency anymore, then a suitable
alternative should be used, not dependencies added manually.
plenary.nvim is often pulled as a dependency of other plugins.
It has filetype definitions in `data/plenary/filetypes` directory.
Even though I don't think there are plugins using it instead of
vim.filetype, but it should be no harm to add this directory by default.
