Helper function to decide which AST nodes to highlight for a selection (internal)

Source: R/print.R
ts_tree_mark_selection1.Rd

This function are for packages implementing new parsers based on the ts package. It is very unlikely that you will need to call this function directly.

Usage

ts_tree_mark_selection1(tree, node)

# S3 method for class 'ts_tree'
ts_tree_mark_selection1(tree, node)

Arguments

tree

Tree-sitter tree.

node

Node id, integer scalar.

Value

Integer vector of node ids to highlight.

Details

In parsers where AST nodes do not correspond one-to-one to DOM nodes it is useful to highlight multiple AST nodes for a single selected DOM node. This generic function can be overridden in such parsers to return multiple AST node ids for a single selected (DOM) node id.

The default implementation simply returns the input node id.

Examples

# This is an internal generic for parser implementations, see the
# tsjsonc and tstoml packages for examples of methods implementing
# custom behavior.
