tree-sitter library for incremental parsing of buffers:
https://tree-sitter.github.io/tree-sitter/parser runtime directory.parser/{lang}.* in any 'runtimepath' directory.
If multiple parsers for the same language are found, the first one is used.
(NOTE: This typically implies the priority "user config > plugins > bundled".)vim.treesitter.language.add('python', { path = "/path/to/python.so" })xml
treesitter parser for buffers with filetype svg or xslt, use:vim.treesitter.language.register('xml', { 'svg', 'xslt' })ENABLE_WASMTIME, then wasm parsers can also be
loaded:vim.treesitter.language.add('python', { path = "/path/to/python.wasm" })query consists of one or
more patterns. A pattern is defined over node types in the syntax tree. A
match corresponds to specific elements of the syntax tree which match a
pattern. Patterns may optionally define captures and predicates. A capture
allows you to associate names with a specific node in a pattern. A predicate
adds arbitrary metadata and conditional data to a match.*.scm files in a queries directory under
runtimepath, where each file contains queries for a specific language and
purpose, e.g., queries/lua/highlights.scm for highlighting Lua files.
By default, the first query on runtimepath is used (which usually implies
that user config takes precedence over plugins, which take precedence over
queries bundled with Nvim). If a query should extend other queries instead
of replacing them, use treesitter-query-modeline-extends.eq? predicate can be used as follows:((identifier) @variable.builtin
(#eq? @variable.builtin "self"))"self" text. Such queries can
be used to highlight built-in functions or variables differently, for instance.eq? treesitter-predicate-eq?((identifier) @variable.builtin (#eq? @variable.builtin "self"))

that contain only whitespace, or are empty) from the end of the node
(for backwards compatibility). Can trim all whitespace from both sides

This will recursively descend in the queries of {lang} unless wrapped

which match a TSNode in the parsed TSTree to a capture that can be
assigned a highlight group. For example, the query(parameters (identifier) @variable.parameter)identifier node inside a function parameters node to the
capture named @variable.parameter. For example, for a Lua codefunction f(foo, bar) end(function_declaration ; [1:1 - 24]
name: (identifier) ; [1:10 - 10]

to Nvim's standard highlight-groups by default (e.g., @comment links to
Comment) but can be overridden in colorschemes.@comment.documentation could be used. If this group
is not defined, the highlighting for an ordinary @comment is used. This way,

capture marks comments as to be checked:(comment) @spell@nospell which disables spellchecking regions with @spell.conceal metadata. By
convention, nodes to be concealed are captured as @conceal, but any capture
can be used. For example, the following query can be used to hide code block

@injection.content - indicates that the captured node should have its
contents re-parsed using another language.
@injection.language - indicates that the captured node’s text may
contain the name of a language that should be used to re-parse the
@injection.content.
@injection.filename - indicates that the captured node’s text may
contain a filename; the corresponding filetype is then looked-up up via
vim.filetype.match() and treated as the name of a language that should
be used to re-parse the @injection.content.
injection.language - can be used to hard-code the name of a specific
language.
injection.combined - indicates that all of the matching nodes in the
tree should have their content parsed as one nested document.
injection.include-children - indicates that the @injection.content
node's entire text should be re-parsed, including the text of its child
nodes. By default, child nodes' text will be excluded from the injected
document.
injection.self - indicates that the node's text should be parsed with
the same language as the node's LanguageTree.
injection.parent - indicates that the captured node’s text should
be parsed with the same language as the node's parent LanguageTree.
