SCRIPTING ENGINE 路 MULTIPLATFORM EXAMPLES
One KitsuneScript engine
Lexer, parser, AST, interpreter i narz臋dzia edytora pochodz膮 z jednego kodu KMP na ka偶dej platformie.
The lexer, parser, AST, interpreter and editor tooling come from one KMP codebase on every platform.
1. Instalacja wsp贸lnego silnika1. Install the shared engine
kotlin {
sourceSets {
commonMain.dependencies {
implementation("rip.nerd.kitsunescript:kitsunescript:3.0.0")
}
}
}
Jest jeden logiczny artefakt. Gradle wybiera wariant Android, JVM/Desktop, Wasm, iosArm64, iosSimulatorArm64 lub iosX64. Nie istnieje okrojony parser iOS ani osobny kitsunescript-ios. Snapshot u偶ywa 3.0.1-SNAPSHOT.
There is one logical artifact. Gradle selects Android, JVM/Desktop, Wasm, iosArm64, iosSimulatorArm64 or iosX64. There is no reduced iOS parser or separate kitsunescript-ios. The snapshot uses 3.0.1-SNAPSHOT.
2. commonMain, Android, Desktop i Web/Wasm2. commonMain, Android, Desktop and Web/Wasm
val engine = KitsuneScriptEngine.builder()
.maxSteps(200_000)
.maxCallDepth(64)
.maxStringLength(1_000_000)
.addFunction("appVersion", HostFunction { _, _ -> Value.Str(APP_VERSION) })
.withSourceLoader { path -> appSources[path] }
.build()
try {
val value = engine.evalSuspend(
"""
import "rules.ks" in rules;
rules.calculate(12);
""".trimIndent(),
sourceName = "main.ks"
)
render(value.asString())
} finally {
engine.close()
}
Android mo偶e zasila膰 appSources z assets, Desktop z zasob贸w albo sandboxa aplikacji, a Web z bundla lub kontrolowanego fetch. SourceLoader nie daje skryptowi samodzielnego dost臋pu do systemu plik贸w ani sieci.
Android may load appSources from assets, Desktop from resources or the application sandbox, and Web from a bundle or controlled fetch. SourceLoader does not grant scripts direct filesystem or network access.
3. iOS / Swift
val scripts = KitsuneScriptSwift(instanceId = "editor", maxSteps = 200_000)
val result = scripts.executeWithParameters(
source = "send(global.params[0] * 2);",
parametersJson = "[21]"
)
if (!result.success) showError(result.error.orEmpty())
scripts.close()
Kod Kotlin w iosMain mo偶e u偶ywa膰 bezpo艣rednio KitsuneScriptEngine. Fasada KitsuneScriptSwift eksportuje do Swift proste typy String/JSON. executeBundle odrzuca .., niebezpieczne 艣cie偶ki, zbyt wiele plik贸w i zbyt du偶y JSON.
Kotlin code in iosMain may use KitsuneScriptEngine directly. KitsuneScriptSwift exports String/JSON-friendly APIs to Swift. executeBundle rejects .., unsafe paths, excessive file counts and oversized JSON.
4. Parser strict, recovery i edytor4. Strict parser, recovery and editor tooling
val strictAst = Parser(Lexer(source).scanTokens()).parse()
val editorResult = Parser(Lexer(source).scanTokens()).parseRecovering()
val diagnostics = KitsuneScriptLanguageService().diagnose(source, "draft.ks")
val formatted = KitsuneScriptFormatter.format(source, indentSize = 4)
parse() ko艅czy prac臋 na pierwszym b艂臋dzie i s艂u偶y do wykonania lub CI. parseRecovering() zachowuje cz臋艣ciowe AST i wiele diagnostyk dla edytora. Regu艂y gramatyki, precedence, synchronizacja i format diagnostyk s膮 opisane w dokumentacji parsera HTML.
parse() stops at the first error and suits execution or CI. parseRecovering() preserves a partial AST and multiple diagnostics for editors. Grammar, precedence, synchronization and diagnostic formats are covered in the HTML parser documentation.
5. Funkcje hosta zale偶ne od platformy5. Platform-dependent host functions
engine.register("openDocument", HostFunction { args, _ ->
val id = args.firstOrNull()?.asString() ?: return@HostFunction Value.Null
val text = platformDocuments.readAllowed(id)
Value.Str(text)
})
Silnik nie wymusza dostawcy plik贸w, HTTP, UI ani p艂atno艣ci. W膮ski adapter zaimplementuj w androidMain, iosMain, jvmMain albo wasmJsMain. Dla niezaufanych skrypt贸w nie przyznawaj zb臋dnych capability i ustaw limity wykonania.
The engine does not force filesystem, HTTP, UI or payment providers. Implement a narrow adapter in androidMain, iosMain, jvmMain or wasmJsMain. Do not grant unnecessary capabilities to untrusted scripts and always configure execution limits.
6. Aplikacje demonstracyjne i testy6. Demo applications and tests
| Host | Pokrywany zakresCovered scope |
|---|---|
| Android playground | Execution, modules, imports, events and host UI |
| JVM/Desktop | Engine, parser, formatter, lint and host functions |
| Web/Wasm | The same engine/parser and browser-safe host adapters |
| iOS | iosArm64, iosSimulatorArm64, iosX64 and Swift facade |
Testy symulatora iOS uruchamia runner macOS; pozosta艂e 艣rodowiska weryfikuj膮 kompilacj臋 wsp贸lnego silnika i parsera.
A macOS runner executes iOS simulator tests; the remaining environments verify compilation of the shared engine and parser.
