# Kotlin Tree Sitter SDK

Kotlin sdk for [tree-sitter](https://tree-sitter.github.io/tree-sitter/)

## Install

### Prepare `tree-sitter` binaries

Prepare binaries with tree-sitter and required languages.

[Optional prebuilt binaries](https://github.com/Endoqa/tree-sitter-prebuilt)

### Add maven repository

```

https://maven.endoqa.io

```

### Add dependencies

#### C-style api

```

io.endoqa:tree-sitter-c:0.0.2

```

#### Object-style api:

```

io.endoqa:tree-sitter:0.0.3

```

## Before Start

### Load native libraries

```kotlin

System.load("/absolute/path/to/tree-sitter.*")

System.load("/absolute/path/to/tree-sitter-.*")

```

Pick api style:

- [Kotlin](#get-started)

- [C-style](#get-started-c-style)

## Get Started

```kotlin

val parser = Parser()

val clang = Language.getLanguage("c")

parser.setLanguage(clang)

val tree = parser.parse(sourceCode)

val rootNode = tree.rootNode

rootNode.namedChildren.forEach { node ->

    println(node.symbol)

}

```

## Get Started (C-Style)

All api are identical to c api

[Using Parser - Get Started](https://tree-sitter.github.io/tree-sitter/using-parsers)

### Obtain a language

```kotlin

val languageMethod = Linker.nativeLinker().downcallHandle(

    RuntimeHelper.symbolLookup.find("tree_sitter_").get(),

    FunctionDescriptor.of(ValueLayout.ADDRESS)

)

val language: Pointer = languageMethod.invokeExact() as MemorySegment

```

### Use parser

```kotlin

val parser = ts_parser_new()

ts_parser_set_language(parser, language)

val source: MemorySegment = TODO("allocate source")

ts_parser_parse_string(

    parser,

    MemorySegment.NULL,

    source,

    sourceLen

)

val rootNode = ts_tree_root_node(tree)

ts_tree_delete(tree)

ts_parser_delete(parser)

```
