--- Create a new LSP client and start a language server or reuses an already
 | 
						|
--- running client if one is found matching `name` and `root_dir`.
 | 
						|
--- Attaches the current buffer to the client.
 | 
						|
---
 | 
						|
--- Example:
 | 
						|
---
 | 
						|
--- ```lua
 | 
						|
--- vim.lsp.start({
 | 
						|
---    name = 'my-server-name',
 | 
						|
---    cmd = {'name-of-language-server-executable'},
 | 
						|
---    root_dir = vim.fs.root(0, {'pyproject.toml', 'setup.py'}),
 | 
						|
--- })
 | 
						|
--- ```
 | 
						|
---
 | 
						|
--- See |vim.lsp.start_client()| for all available options. The most important are:
 | 
						|
---
 | 
						|
--- - `name` arbitrary name for the LSP client. Should be unique per language server.
 | 
						|
--- - `cmd` command string[] or function, described at |vim.lsp.start_client()|.
 | 
						|
--- - `root_dir` path to the project root. By default this is used to decide if an existing client
 | 
						|
---   should be re-used. The example above uses |vim.fs.root()| and |vim.fs.dirname()| to detect
 | 
						|
---   the root by traversing the file system upwards starting from the current directory until
 | 
						|
---   either a `pyproject.toml` or `setup.py` file is found.
 | 
						|
--- - `workspace_folders` list of `{ uri:string, name: string }` tables specifying the project root
 | 
						|
---   folders used by the language server. If `nil` the property is derived from `root_dir` for
 | 
						|
---   convenience.
 | 
						|
---
 | 
						|
--- Language servers use this information to discover metadata like the
 | 
						|
--- dependencies of your project and they tend to index the contents within the
 | 
						|
--- project folder.
 | 
						|
---
 | 
						|
---
 | 
						|
--- To ensure a language server is only started for languages it can handle,
 | 
						|
--- make sure to call |vim.lsp.start()| within a |FileType| autocmd.
 | 
						|
--- Either use |:au|, |nvim_create_autocmd()| or put the call in a

--- Registry for client side commands.
 | 
						|
--- This is an extension point for plugins to handle custom commands which are
 | 
						|
--- not part of the core language server protocol specification.
 | 
						|
---
 | 
						|
--- The registry is a table where the key is a unique command name,
 | 
						|
--- and the value is a function which is called if any LSP action
 | 
						|
--- (code action, code lenses, ...) triggers the command.
 | 
						|
---
 | 
						|
--- If a LSP response contains a command for which no matching entry is
 | 
						|
--- available in this registry, the command will be executed via the LSP server
 | 
						|
--- using `workspace/executeCommand`.
 | 
						|
---
 | 
						|
--- The first argument to the function will be the `Command`:
 | 
						|
---   Command
 | 
						|
---     title: String
 | 
						|
---     command: String
 | 
						|
---     arguments?: any[]
 | 
						|
---
 | 
						|
--- The second argument is the `ctx` of |lsp-handler|
 | 
						|
--- @type table<string,function>
