TreeSitter.DotNet 1.3.0

About

Provides .NET bindings for the tree-sitter parsing library. Also includes the native tree-sitter parsing library and a complete set of native language parsing libraries.

Key Features

• .NET bindings for the tree-sitter parsing library.
• Includes native libraries for the tree-sitter parsing library and language grammars.
• Includes 28+ language grammars.
• Work with all .NET languages such as C#, F#, and VB.NET.
• Work with Windows (x86, x64, arm64), Linux (x86, x64, arm, arm64), and macOS (x64, arm64).
• Support for predicates queries.
• Passes the WebAssembly bindings test suite.

How to Use

Parsing source code:

using TreeSitter;

using var language = new Language("JavaScript");
using var parser = new Parser(language);
using var tree = parser.Parse("console.log('Hello World');")!;
Console.WriteLine($"Root node: {tree.RootNode}");

Expected output:

Root node: (program (expression_statement (call_expression function: (member_expression object: (identifier) property: (property_identifier)) arguments: (arguments (string (string_fragment))))))

Running queries:

using TreeSitter;

using var language = new Language("JavaScript");
using var parser = new Parser(language);
using var tree = parser.Parse("function one() { function two() {} }")!;
using var query = new Query(language, "(function_declaration name: (identifier) @fn)");
foreach (var capture in query.Execute(tree.RootNode).Captures)
{
 Console.WriteLine($"Found function: {capture.Node.Text}");
}

Expected output:

Found function: one
Found function: two
