Kotlin Shell Examples

This repository provides examples on using Kotlin Shell library

The examples can be run both via command line and Intellij IDEA.

All examples from kotlin can be executes as scripts and all examples from kts can be executed as part of Kotlin code.

As scripting support in Intellij IDEA is still under development, examples may not run properly on every versions. Despite the highlighting and completion should work fine.

run it with command line

kotlin

type:

./gradlew -Psample=[RELATIVE-CLASS-PATH] -Plogs=true execute [--args="ARGS"]

example:

$ cd kotlin
$ ./gradlew -Psample=basic.HelloKt execute
hello world!

To see logs add -Plogs=true parameter.

kts

To run scripts you need kshell installed

type:

cd kts
kshell src/kotlin/[PATH-TO-SAMPLE] [ARGS]

example:

$ cd kts
$ kshell src/kotlin/basic/hello.sh.kts
hello world!

run it with Intellij IDEA

kotlin

After importing Gradle project you will be able to run main() functions in sample classes.

kts

After importing Gradle project you will be able to run script files.

file template

File kts/fileTemplate_sh_kts contains template definition for Intellij. To use it put this file in ~/Library/Preferences/IntelliJIdea/fileTemplates with name KotlinShell.sh.kts.

logging

Kotlin Shell features slf4j logging interface. All examples use NOP logger by default. Configurations for loggers can be found under resources/log4j2.xml.

kotlin

By default Gradle project imports NOP logger. To change it use these instructions.

kts

Both kshell and Gradle uses NOP logger by default. You can change this dependency manually to see the logs.

side by side examples

In sidebyside package there are located side by side examples of scripts written with Kotlin Shell and Bash. They are always equal in terms of evaluation.
