RubyMine 2018.3 Help

Platform Properties Reference'

The idea.properties file can include both settings that are specific for the IntelliJ platform and any other relevant properties. To configure platform properties, on the Help menu, click Edit Custom Properties.

You can use macros with any property name to insert its value, for example, use ${user.home} to specify paths relative to the user's home directory.

Property

Default value

Description

idea.chooser.lookup.for.project.dirstrue

Defines whether RubyMine should look inside directories for valid projects to mark such directories with the corresponding icon. If you disable this property, such lookups will not be performed outside of the user's home directory.

idea.cycle.buffer.size1024

Sets the maximum size of the console cyclic buffer (in kylobytes). If the console output size exceeds this value, oldest lines are deleted. To disable the cyclic buffer, set idea.cycle.buffer.size=disabled.

idea.dynamic.classpathfalse

Defines whether long classpath should be written to a file and read from there instead of passing it on the command line. By default, this is disabled and if the command exceeds the limit of characters allowed by the shell, it fails.

idea.max.content.load.filesize20000

Sets the maximum size of files (in kylobytes) that RubyMine is able to open and process.

idea.max.intellisense.filesize2500

Sets the maximum size of files (in kilobytes) for which RubyMine provides code assistance. Code assistance for large files can decrease editor performance and increase memory consumption.

idea.max.vcs.loaded.size.kb20480

Sets the maximum size (in kilobytes) that RubyMine loads for showing past file contents when comparing changes.

idea.no.launcherfalse

Defines whether a special launcher should be used when running processes from RubyMine. The launcher is enabled by default and provides "soft exit" and "thread dump" features. To disable it, set idea.no.launcher=true

idea.popup.weightheavy

If your window manager is configured to change focus with the mouse and auto-raise windows, set this property to medium, which will prevent problems with pop-up menus on some configurations.

idea.ProcessCanceledException

enabled

Defines whether RubyMine should throw ProcessCanceledException when user activity is detected. Disable this only when developing plugins and you need to debug the IDE itself (activities related to PSI, which are performed in the background error analysis thread), because it can cause significant slowdowns and lockups.

${idea.home} macro

Use ${idea.home} macro to specify location relative to IDE installation home.

Also use ${xxx} where xxx is any java property (including defined in the previous lines of this file) to refer to its value.

Path to the IDE config folder

Uncomment this option if you want to customize path to IDE config folder.

idea.config.path=${user.home}/.RubyMine/config

Path to IDE system folder

Uncomment this option if you want to customize path to IDE system folder.

idea.system.path=${user.home}/.RubyMine/system

Path to user installed plugins

Uncomment this option if you want to customize path to user installed plugins folder.

idea.plugins.path=${user.home}/.RubyMine/config/plugins

Path to IDE logs folder

Uncomment this option if you want to customize path to IDE logs folder.

idea.log.path=${user.home}/.RubyMine/system/log

Maximum file size

Maximum file size (kilobytes) IDE should provide code assistance for. The larger file is, the slower its editor works and higher overall system memory requirements are, if code assistance is enabled. https://youtrack.jetbrains.com/issue/IDEA-72543

Remove this property or set to a very large number, if you need code assistance for any files to be available, regardless of their size.

idea.max.intellisense.filesize=2500

Large file size limit

The maximum file size that IDE accepts for loading. For example, when you have a file that exceeds the specified limit for "Find in Path" action, IDE will ignore such file. You can override the default maximum size by manually specifying the size limit.

idea.max.content.load.filesize=2000

Console cyclic buffer

This option controls console cyclic buffer: keeps the console output size not higher than the specified buffer size (Kb). Older lines are deleted. In order to disable cycle buffer, use idea.cycle.buffer.size=disabled

idea.cycle.buffer.size=1024

Launcher

Configure if a special launcher should be used when running processes from within IDE. Using Launcher enables "soft exit" and "thread dump" features.

idea.no.launcher=false

Classpath

To avoid too long classpath

idea.dynamic.classpath=false

ProcessCanceledException

Uncomment this property to prevent IDE from throwing ProcessCanceledException when user activity detected. This option is only useful for plugin developers, while debugging PSI related activities performed in background error analysis thread.

DO NOT UNCOMMENT THIS UNLESS YOU'RE DEBUGGING THE IDE ITSELF. Significant slowdowns and lockups will happen otherwise.

idea.ProcessCanceledException=disabled

Pop-up window weight

There are two possible values of idea.popup.weight property: "heavy" and "medium". If you have WM configured as "Focus follows mouse with Auto Raise" then you have to set this property to "medium". It prevents problems with the pop-up menus on some configurations.

idea.popup.weight=heavy

System anti-aliasing

Use default anti-aliasing in system, i.e. override value of "Settings|Editor|Appearance|Use anti-aliased font" option. May be useful when using Windows Remote Desktop Connection for instance.

idea.use.default.antialiasing.in.editor=false

Repaint

Disabling this property may lead to visual glitches like blinking and fail to repaint on certain display adapter cards.

sun.java2d.noddraw=true

Editor performance

Removing this property may lead to editor performance degradation under Windows.

sun.java2d.d3d=false

Slow scrolling

Workaround for slow scrolling in JDK6.

swing.bufferPerWindow=false

Editor performance under X Window

Removing this property may lead to editor performance degradation under X Window.

sun.java2d.pmoffscreen=false

Avoid long hangs

Workaround to avoid long hangs while accessing clipboard under macOS.

ide.mac.useNativeClipboard=True

Copy library jars

IDE copies library jars to prevent their locking. If copying is not desirable, specify "true"

idea.jars.nocopy=false

Start the JVM in debug mode

The VM option value to be used to start the JVM in debug mode. Some JREs define it in a different way (-XXdebug in Oracle VM)

idea.xdebug.key=-Xdebug

Switch into JMX 1.0 compatibility mode.

Uncomment this option to be able to run RubyMine using J2SDK 1.5+ while working with application servers (like WebLogic) running 1.4.

jmx.serial.form=1.0

Fatal errors notifications

Change to 'enabled' if you want to receive instant visual notifications about fatal errors that happen to an IDE or plugins installed.

idea.fatal.error.notification=disabled
