The namespacing for healthchecks for neovim modules is inconsistent and confusing. The completion for `:checkhealth` with `--clean` gives ``` nvim provider.clipboard provider.node provider.perl provider.python provider.ruby vim.lsp vim.treesitter ``` There are now three top-level module names for nvim: `nvim`, `provider` and `vim` with no signs of stopping. The `nvim` name is especially confusing as it does not contain all neovim checkhealths, which makes it almost a decoy healthcheck. The confusion only worsens if you add plugins to the mix: ``` lazy mason nvim nvim-treesitter provider.clipboard provider.node provider.perl provider.python provider.ruby telescope vim.lsp vim.treesitter ``` Another problem with the current approach is that it's not easy to run nvim-only healthchecks since they don't share the same namespace. The current approach would be to run `:che nvim vim.* provider.*` and would also require the user to know these are the neovim modules. Instead, use this alternative structure: ``` vim.health vim.lsp vim.provider.clipboard vim.provider.node vim.provider.perl vim.provider.python vim.provider.ruby vim.treesitter ``` and ``` lazy mason nvim-treesitter telescope vim.health vim.lsp vim.provider.clipboard vim.provider.node vim.provider.perl vim.provider.python vim.provider.ruby vim.treesitter ``` Now, the entries are properly sorted and running nvim-only healthchecks requires running only `:che vim.*`.
