Documentation

Maximum buffer size (in bytes) for enabling tree-sitter parsing.

A typical tree-sitter parser needs 10 times as much memory as the buffer it parses. Also, the tree-sitter library has a hard limit of max unsigned 32-bit value for byte offsets into buffer text.

This variable was added, or its default value changed, in Emacs 29.1.
