Kotlin Programming Cookbook

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The corresponding sourceSets property should be updated if not using the default convention."

A block of code is set as follows:

sourceSets {   main.kotlin.srcDirs += 'src/main/myKotlin'   main.java.srcDirs += 'src/main/myJava'}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

sourceSets {   main.java.srcDirs += 'src/main/kotlin/'}

Any command-line input or output is written as follows:

$ kotlinc hello.kt -include-runtime ...
