### Parse Kotlin Code with KTreeSitter

Source: https://github.com/tree-sitter/kotlin-tree-sitter/blob/master/ktreesitter/README.md

This example shows the fundamental steps to parse a Kotlin code string using KTreeSitter: initializing a language, creating a parser, parsing the text, and accessing the root node of the syntax tree for inspection.

```Kotlin
val language = Language(TreeSitterKotlin.language())
val parser = Parser(language)
val tree = parser.parse("fun main() {}")
val rootNode = tree.rootNode

assert(rootNode.type == "source_file")
assert(rootNode.startPoint.column == 0)
assert(rootNode.endPoint.column == 13)
```

### Install KTreeSitter Plugin in Gradle

Source: https://github.com/tree-sitter/kotlin-tree-sitter/blob/master/ktreesitter-plugin/README.md

This snippet demonstrates how to add the KTreeSitter plugin to a Gradle project's build script, enabling its functionalities. It includes repository and plugin ID declarations necessary for plugin resolution.

```Groovy
buildscript {
  repositories {
    gradlePluginPortal()
  }
}

plugins {
  id("io.github.tree-sitter.ktreesitter-plugin")
}
```

### Install KTreeSitter Dependency in Kotlin

Source: https://github.com/tree-sitter/kotlin-tree-sitter/blob/master/ktreesitter/README.md

This snippet demonstrates how to add the KTreeSitter library as a dependency in a Kotlin project's `build.gradle.kts` file, specifying the artifact and repository for build systems like Gradle.

```Kotlin
dependencies {
    implementation("io.github.tree-sitter:ktreesitter") version $ktreesitterVersion
}

repositories {
    mavenCentral()
}
```

### Configure KTreeSitter Grammar Options in Gradle

Source: https://github.com/tree-sitter/kotlin-tree-sitter/blob/master/ktreesitter-plugin/README.md

This configuration block defines the essential settings for a KTreeSitter grammar within a Gradle project. It covers both default and required options such as base directory, interop and library names, grammar and class names, package, and source file paths for the grammar.

```Groovy
grammar {
  /* Default options */
  // The base directory of the grammar
  baseDir = projectDir.parentFile.parentFile
  // The name of the C interop def file
  interopName = "grammar"
  // The name of the JNI library
  libraryName = "ktreesitter-$grammarName"

  /* Required options */
  // The name of the grammar
  grammarName = "java"
  // The name of the class
  className = "TreeSitterJava"
  // The name of the package
  packageName = "io.github.treesitter.ktreesitter.java"
  // The source files of the grammar
  files = arrayOf(
    baseDir.get().resolve("src/parser.c")
    // baseDir.get().resolve("src/scanner.c")
  )
}
```

### Configure CMake Build for ktreesitter Shared Library

Source: https://github.com/tree-sitter/kotlin-tree-sitter/blob/master/ktreesitter/CMakeLists.txt

This CMake script configures the build for the `ktreesitter` shared library. It sets the minimum CMake version, reads the project version from `gradle.properties`, defines compiler standards and options (including platform-specific flags for MSVC and GCC/Clang), includes necessary directories for JNI and Tree-sitter, defines `TREE_SITTER_HIDE_SYMBOLS`, and compiles the shared library from specified C source files.

```CMake
cmake_minimum_required(VERSION 3.12.0)

file(READ ../gradle.properties GRADLE_PROPERTIES)
string(REGEX MATCH "project[.]version=([0-9.]+)" _ ${GRADLE_PROPERTIES})

project(ktreesitter VERSION ${CMAKE_MATCH_1} LANGUAGES C)

find_package(JNI REQUIRED)

set(CMAKE_C_STANDARD 11)

if(MSVC)
    add_compile_options(/W3 /wd4244)
else(MSVC)
    set(CMAKE_C_VISIBILITY_PRESET hidden)
    add_compile_options(-Wall -Wextra
                        -Wno-unused-parameter
                        -Wno-cast-function-type
                        -Werror=incompatible-pointer-types
                        -Werror=implicit-function-declaration)
endif(MSVC)

include_directories(${JNI_INCLUDE_DIRS}
                    ../tree-sitter/lib/src
                    ../tree-sitter/lib/include)

add_compile_definitions(TREE_SITTER_HIDE_SYMBOLS)

add_library(ktreesitter SHARED
            ./src/jni/language.c
            ./src/jni/lookahead_iterator.c
            ./src/jni/node.c
            ./src/jni/parser.c
            ./src/jni/query.c
            ./src/jni/tree.c
            ./src/jni/tree_cursor.c
            ./src/jni/module.c
            ../tree-sitter/lib/src/lib.c)

set_target_properties(ktreesitter PROPERTIES DEFINE_SYMBOL "")

install(TARGETS ktreesitter ARCHIVE EXCLUDE_FROM_ALL)
```
