Secure Kotlin scripting and binary lambda-scripts

keplin

Extended Kotlin Scripting

Gradle /Maven

With Kotlin 1.2.+ in your classpath, add:

artifact	GAV
keplin-core	uy.kohesive.keplin:keplin-core
keplin-maven-resolver	uy.kohesive.keplin:keplin-maven-resolver
keplin-jsr223-kotlin-engine	uy.kohesive.keplin:keplin-jsr223-kotlin-engine

TODO:

• document the modules
• add maven / file resolver Cuarentena-like support for whitelisting GAV, and local file patterns
• add Cuarentena support for securing each script engine.

Current Modules:

keplin-core

• a simple Repl class SimplifiedRepl
• a file based JAR resolver that can be used with @file:DependsOnJar(fileInDirRepo|fullyQualifiedFile) and @file:DirRepository(fullQyalifiedPath) annotations in the script to load JAR files
• a script definition that can automatically imply imports KotlinScriptDefinitionEx

See unit tests

keplin-maven-resolver

Allowing Maven artifacts to be specified and used in Kotlin scripts.

• a maven based resolver (maven-resolver dependency) used with @file:MavenRepository(mavenRepoUrl) and @file:DependsOnMaven(mavenGAV) annotations in the script to load Maven dependencies

See unit tests

keplin-jsr223-kotlin-engine

• keplin-kotlin-repl-compilable JSR223 engine also implementing Compilable and Invocable interfaces
• keplin-kotlin-repl-eval-only JSR223 engine that is atomic eval only (compile+eval) and also Invocable interface

See unit tests

Kotlin-Jupyter

Keplin is used in the related Kotlin-Jupyter project to provide a basic REPL for Jupyter notebooks or console.
