** Emacs can be built with the tree-sitter parsing library.

This library, together with grammar libraries, provides incremental

parsing capabilities for several popular programming languages and

other formatted files. Emacs built with this library offers major

tree-sitter's parsers. If you have the tree-sitter library

installed, the configure script will automatically include it in the

Where major modes already exist in Emacs for editing certain kinds of

The new modes based on tree-sitter are for now entirely optional, and

you must turn them on manually, or load them in your init file, or

Where no major modes previously existed in Emacs for editing the kinds

of files for which Emacs now provides a tree-sitter based mode, Emacs

will now try to enable these new modes automatically when you visit

such files, and will display a warning if the tree-sitter library or

the parser grammar library is not available. To prevent the warnings,

either build Emacs with tree-sitter and install the grammar libraries,

even 'fundamental-mode') for those kinds of files.
