Nvim 0.11: Treesitter, TUI, and UI Updates

cursor position when the sequence was received. TREESITTER • |LanguageTree:node_for_range()| gets anonymous and named nodes for a range • |vim.treesitter.get_node()| now takes an option `include_anonymous`, default false, which allows it to return anonymous nodes as well as named nodes. • |treesitter-directive-trim!| can trim all whitespace (not just empty lines) from both sides of a node. • |vim.treesitter.get_captures_at_pos()| now returns the `id` of each capture • New |TSNode:child_with_descendant()|, which efficiently gets the node's child that contains a given node as descendant. • |LanguageTree:parse()| optionally supports asynchronous invocation, which is activated by passing the `on_parse` callback parameter. • |vim.treesitter.query.set()| can now inherit and/or extend runtime file queries in addition to overriding. • |LanguageTree:is_valid()| now accepts a range parameter to narrow the scope of the validity check. • |:InspectTree| now shows which nodes are missing. • Bundled markdown highlight queries use `conceal_lines` metadata to conceal code block fence lines vertically. • |vim.treesitter.language.inspect()| shows additional information, including parser version for ABI 15 parsers. • |TSQuery:disable_pattern()| and |TSQuery:disable_capture()| to turn off a specific pattern or capture in a query. • |vim.treesitter.get_captures_at_pos()| returns the `pattern_id` of the pattern used to match each capture. • |Query:iter_captures()| now accepts an `opts` parameter, similar to |Query:iter_matches()|. TUI • The builtin UI declares info |nvim_set_client_info()| on its channel. See |startup-tui|. To see the current UI info, try this: > :lua =vim.api.nvim_get_chan_info(vim.api.nvim_list_uis()[1].chan) • |log| messages written by the builtin UI client (TUI, |--remote-ui|) are now prefixed with "ui" instead of "?". • The TUI will re-query the terminal's background color when a theme update notification is received and Nvim will update 'background' accordingly. UI • |:detach| the current UI, let the Nvim server continue running as a background process. Works with the builtin TUI, and all GUIs. • |vim.ui.open()| (by default bound to |gx|) accepts an `opt.cmd` parameter which controls the tool used to open the given path or URL. If you want to globally set this, you can override vim.ui.open using the same approach described at |vim.paste()|. • `vim.ui.open()` now supports [lemonade](https://github.com/lemonade-command/lemonade) as an option for opening urls/files. This is handy if you are in an ssh connection and use `lemonade`. • The |ins-completion-menu| now supports cascading highlight styles. |hl-PmenuSel| and |hl-PmenuMatch| both inherit from |hl-Pmenu|, and |hl-PmenuMatchSel| inherits highlights from both |hl-PmenuSel| and |hl-PmenuMatch|.

This section details updates to Treesitter, the TUI, and UI features in Nvim 0.11. Treesitter enhancements include more options for working with nodes, queries, and captures, plus improved markdown highlighting and inspection. The TUI now declares client info and re-queries the terminal's background color on theme updates. The UI introduces features such as detaching, customizing the tool used to open URLs and files with `vim.ui.open()`, and cascading highlight styles for the completion menu.
