Nvim 0.10 Release Notes: Treesitter, TUI, UI and Changed Features

• Bundled parser and queries (highlight, folds) for Markdown (used for LSP hover). • |:InspectTree| shows root nodes. • |:InspectTree| now supports |folding|. • |:InspectTree| shows node ranges in 0-based instead of 1-based indexing. • |vim.treesitter.foldexpr()| now recognizes folds captured using a quantified query pattern. • |vim.treesitter.query.omnifunc()| provides completion in treesitter query files (set by default). • |vim.treesitter.query.edit()| provides live editing of treesitter queries. • |Query:iter_matches()| now has the ability to set the maximum start depth for matches. • `@injection.language` now has smarter resolution and will fall back to language aliases (e.g., filetype or custom shorthands) registered via |vim.treesitter.language.register()| and/or attempt lower case variants of the text. • `@injection.filename` will try to match the node text via |vim.filetype.match()| and treat the result as a language name in the same way as `@injection.language`. • The `#set!` directive supports `injection.self` and `injection.parent` for injecting either the current node's language or the parent |LanguageTree|'s language, respectively. • The `#set!` directive can set the "url" property of a node to have the node emit a hyperlink. Hyperlinks are UI specific: in the TUI, the OSC 8 control sequence is used. • Improved error messages for query parsing. • TUI: • Builtin TUI can now recognize "super" (|<D-|) and "meta" (|<T-|) modifiers in a terminal emulator that supports |tui-csiu|. • The |TermResponse| event can be used with |v:termresponse| to read escape sequence responses from the host terminal. • A clipboard provider which uses OSC 52 to copy the selection to the system clipboard is now bundled by default and will be automatically enabled under certain conditions. |clipboard-osc52| • 'termsync' option asks the host terminal to buffer screen updates until the redraw cycle is complete. Requires support from the host terminal. • UI: • Enhanced support for rendering multibyte characters using composing characters: the maximum limit was increased from 1+6 codepoints to 31 bytes, which is guaranteed to fit all chars from before but often more. • NOTE: the regexp engine still has a hard-coded limit of considering 6 composing chars only. ============================================================================== CHANGED FEATURES These existing features changed their behavior. • API: • |nvim_buf_call()| and |nvim_win_call()| now preserve any return value (NB: not multiple return values) • Editor: • |gx| now uses |vim.ui.open()| and not netrw. To customize, you can redefine `vim.ui.open` or remap `gx`. To continue

Nvim 0.10 updates Treesitter with bundled Markdown support, enhanced `:InspectTree` features, fold expression recognition, query completion/editing, match iteration control, injection language resolution, and hyperlink support via `#set!` directive, along with improved query parsing error messages. The TUI now recognizes "super" and "meta" modifiers, supports reading escape sequence responses from the host terminal using `TermResponse`, bundles an OSC 52 clipboard provider, and introduces the 'termsync' option. The UI improves multibyte character rendering with an increased codepoint limit. Changed features include `nvim_buf_call()` and `nvim_win_call()` preserving return values, and `gx` using `vim.ui.open()` instead of netrw.
