Kotlin compiler server

A REST server for compiling and executing Kotlin code. The server provides the API for Kotlin Playground library.

How to start 🏁

Simple Spring Boot application

Download Kotlin dependencies and build an executor before starting the server:

$ ./gradlew build -x test

Start the Spring Boot project. The main class: com.compiler.server.CompilerApplication

From Docker Hub

View images on Docker Hub.

docker pull prendota/kotlin-compiler-server

From Amazon lambda

Based on aws-serverless-container.

$ ./gradlew buildLambda

Getting .zip file from build/distributions.

Lambda handler: com.compiler.server.lambdas.StreamLambdaHandler::handleRequest.

Publish your Lambda function: you can follow the instructions in AWS Lambda's documentation on how to package your function for deployment.

      "text": "import org.junit.Assert\nimport org.junit.Test\n\nclass TestStart {\n    @Test fun testOk() {\n        Assert.assertEquals(\"OK\", start())\n    }\n}"
    },
    {
      "name": "test1.kt",
      "text": "package koans.util\n\nfun String.toMessage() = \"The function '\''$this'\'' is implemented incorrectly\"\n\nfun String.toMessageInEquals() = toMessage().inEquals()\n\nfun String.inEquals() = this"
    }
  ]
}'

Get code completions for a specified place in code

curl -X POST \
  'http://localhost:8080/api/compiler/complete?line=1&ch=12' \
  -H 'Content-Type: application/json' \
  -d '{

    }
  ]
}'

Get code analysis results

curl -X POST \
  http://localhost:8080/api/compiler/highlight \
  -H 'Content-Type: application/json' \
  -d '{

    {
      "name": "File.kt",
      "text": "fun main() {\n    println(\"Hello, world!!!\")ass\n}"
    }
  ]
}'

Get the current Kotlin version

curl -X GET http://localhost:8080/versions

The server also supports an API for the Kotlin Playground library.

How to add your dependencies to kotlin compiler 📚

Just put whatever you need as dependencies to build.gradle.kts via a task called kotlinDependency:

 kotlinDependency "your dependency"

NOTE: If the library you're adding uses reflection, accesses the file system, or performs any other type of security-sensitive operations, don't forget to configure the executors.policy. Click here for more information about Java Security Policy.

How to set Java Security Policy in executors.policy

If you want to configure a custom dependency, use the marker @LIB_DIR@:

grant codeBase "file:%%LIB_DIR%%/junit-4.12.jar"{
  permission java.lang.reflect.ReflectPermission "suppressAccessChecks";
  permission java.lang.RuntimePermission "setIO";
  permission java.io.FilePermission "<<ALL FILES>>", "read";
  permission java.lang.RuntimePermission "accessDeclaredMembers";
};

CORS configuration

Set the environment variables

ENV	Default value
ACCESS_CONTROL_ALLOW_ORIGIN_VALUE	*
ACCESS_CONTROL_ALLOW_HEADER_VALUE	*

Kotlin release guide 🚀

Update the kotlin version in gradle.properties
Update the kotlin version in build.gradle.kts
Update the kotlin version in Dockerfile
Make sure everything is going well via the task:

$ ./gradlew build

Save branch with the name of the kotlin version. Pattern: /^[0-9.]+$/ (optional)
Bump version on GitHub releases (optional)
