kotlin-script-toolbox

Kotlin Script Toolbox is a library for handling common operations with Kotlin Script - designed to run on GitHub Actions and locally.

How to set up

Add this in your build.gradle.ktx file:

// all modules (Basic utils + gson + telegram + ...) + `ZeroSetupScope()`
implementation("com.github.omarmiatello.kotlin-script-toolbox:zero-setup:0.1.5")

Alternative, only basic support:

// Basic utils + kotlinx.coroutines
implementation("com.github.omarmiatello.kotlin-script-toolbox:core:0.1.5")
// core + gson utils
implementation("com.github.omarmiatello.kotlin-script-toolbox:gson:0.1.5")
// core + telegram client
implementation("com.github.omarmiatello.kotlin-script-toolbox:telegram:0.1.5")
// core + twitter client
implementation("com.github.omarmiatello.kotlin-script-toolbox:twitter:0.1.5")

How to use (by examples)

See Main.kt to launch all examples.

Read System Property (available in core and zero-setup)

launchKotlinScriptToolbox(
    scope = BaseScope.from(),
    scriptName = "Test read System Property",
) {
    // system env or 'local.properties'
    val secretData = readSystemProperty("SECRET_DATA")
    val secretData2 = readSystemPropertyOrNull("SECRET_DATA_OR_NULL")
    println("System Property 'SECRET_DATA': $secretData")
}

Result (see local.properties):

🏁 Test read System Property - Start!
System Property 'SECRET_DATA': this is only for local env. NOTE: this file (local.properties) should be added to .gitignore
🎉 Test read System Property - Completed in 27ms

Write/read file with text (available in core and zero-setup)

launchKotlinScriptToolbox(
    scope = BaseScope.from(filepathPrefix = "example-data/"),
    scriptName = "Test write/read file with text",
) {
    // files: write text
    writeText("test1.txt", "Ciao")

    // files: read text
    println("test1.txt: ${readTextOrNull("test1.txt")}")
}

Result:

🏁 Test write/read file with text - Start!
test1.txt: Ciao
🎉 Test write/read file with text - Completed in 3ms

Write/read file with objects (serialized as json) (available in zero-setup)

launchKotlinScriptToolbox(
    scope = BaseScope.from(filepathPrefix = "example-data/"),
    scriptName = "Test write/read file with objects (serialized as json)",
) {
    data class MyExample(val p1: String, val p2: Int? = null)

    // files: write json objects
    writeJson("test2-a.json", MyExample(p1 = "test1"))
    writeJson("test2-b.json", MyExample(p1 = "test2", p2 = 3))

    // files: read json objects
    println("test2-a.json to object: ${readJsonOrNull<MyExample>("test2-a.json")}")
    println("test2-b.json to object: ${readJsonOrNull<MyExample>("test2-b.json")}")
}

Result:

🏁 Test write/read file with objects (serialized as json) - Start!
test2-a.json to object: MyExample(p1=test1, p2=null)
test2-b.json to object: MyExample(p1=test2, p2=3)
🎉 Test write/read file with objects (serialized as json) - Completed in 42ms

Send Telegram message (available in telegram and zero-setup)

launchKotlinScriptToolbox(
    scope = TelegramScope.from(apiKey = "my api key", defaultChatIds = listOf("123321")),
    scriptName = "Test Telegram messages",
) {
    sendTelegramMessage("My message")
}

Send Twitter message (tweet) (available in twitter and zero-setup)

launchKotlinScriptToolbox(
    scope = TwitterScope.from(baseScope = BaseScope.from()),
    scriptName = "Test Twitter messages",
) {
    sendTweet("My tweet")
}

Set up of multiple scopes (available in zero-setup)

val baseScope = BaseScope.from()
launchKotlinScriptToolbox(
    scope = object : BaseScope by baseScope,
        TelegramScope by TelegramScope.from(baseScope),
        TwitterScope by TwitterScope.from(baseScope) {},
) {
    sendTelegramMessage("My message")
    sendTelegramMessages(listOf("My message 1", "My message 2"))
    sendTweet("My tweet")
    sendTweets(listOf("My tweet 1", "My tweet 2"))
}

Set up of multiple scopes with ZeroSetupScope (available in zero-setup)

launchKotlinScriptToolbox(scope = ZeroSetupScope()) {
    sendTelegramMessage("My message")
    sendTelegramMessages(listOf("My message 1", "My message 2"))
    sendTweet("My tweet")
    sendTweets(listOf("My tweet 1", "My tweet 2"))
}
