Kotlin compiler

Use this page to configure Kotlin compiler-specific settings.

Item	Description
Generate no warning	If this checkbox is selected, the compiler won't generate warnings in course of compilation; only errors and info messages will be left.
Additional command line parameters	Specify the command-line parameters and options to be passed to the compiler at its start. Refer to the compiler documentation for the available options. If you need more room to type, click to open the Additional command line parameters dialog where the text entry area is larger. When specifying the parameters and options, follow these rules: Use spaces to separate individual parameters and options, for example, `-client -ea -Xmx1024m`. If a parameter or an option includes spaces, enclose the spaces or the argument that contains the spaces in double quotes, for example, `some" "arg` or `"some arg"`. If a parameter or an option includes double quotes (e.g. as part of the argument), escape the double quotes by means of the backslashes, for example, `-Dmy.prop=\"quoted_value\"`.
Keep compiler process alive between invocations	If this checkbox is selected, the compiler process is always alive.
Kotlin to JVM
Enable precise incremental compilation (experimental)	If this checkbox is selected, the improved incremental compilation is turned on. The incremental compilation is still experimental and may work incorrectly in some cases.
Kotlin to JavaScript
Generate source maps	If this checkbox is selected, the compiler generates source maps that set the correspondence between lines in your Kotlin code and in the generated JavaScript code, otherwise your breakpoints will not be recognised and processed correctly.
Output file prefix	Specify the path to the file that will be added as is to the beginning of the generated code. You can enter the path manually, or click and select the required file from the file chooser.
Output file postfix	Specify the path to the file that will be added as is to the end of the generated code. You can enter the path manually, or click and select the required file from the file chooser.
Copy library runtime files	If this checkbox is selected, the JavaScript files from the libraries will be copied to the folder specified in the field Output directory for library runtime files.
Output directory for library runtime files	This field is only enabled, if the checkbox Copy library runtime files is selected. Specify here the target folder for the copied files.
