Tree sitter language object for JSONC

Use this function with ts::ts_tree_new() to create a tree-sitter tree for a JSONC document.

Usage

ts_language_jsonc()

The JSON grammar

The grammar has the following node types. I included some less important nodes in the subsection of other nodes that they are related to.

Comments may appear between any tokens, but they are not part of the grammar.

Use the bracket operator, ts::ts_tree_dom() and ts::ts_tree_ast() to explore the parse tree of a JSON document.
