Customize colors

Settings/Preferences > Editor > Color Scheme > Rainbow Brackets:

Use color generator

If you didn't like the build-in colors, or want some new color but don't want to try out and pick colors. Please use color generator.

Settings/Preferences > Other Settings > Rainbow Brackets > Use color generator

If you turn on this option, we will auto generate some colors for you.

Advanced options of color generator

If you need more control, you can decide the options of color generator by edit the config file,

The value of the option customColorGeneratorOption is a json object, available options are:

hue – Controls the hue of the generated color. You can pass a string representing a color name: red, orange, yellow, green, blue, purple, pink and monochrome are currently supported. If you pass a hexidecimal color string such as #00FFFF, color generator will extract its hue value and use that to generate colors.

luminosity – Controls the luminosity of the generated color. You can specify a string containing bright, light or dark.

Please make sure the value of the option customColorGeneratorOption is escaped in xml format, you can use this tool to do this. Please don't forget to restart your IDE after change the config file.

<application>
  <component name="RainbowSettings">
    <option name="useColorGenerator" value="true" />
    <option name="customColorGeneratorOption" value="{&quot;luminosity&quot;: &quot;light&quot;,&quot;hue&quot;: &quot;blue&quot;}"/>
  </component>
</application>

Want to config the number of colors?

Settings/Preferences > Other Settings > Rainbow Brackets > Number of colors: 5 or more

And you can use the color generator and config you number of colors at the same time.

NOTE: For default and darcula color scheme(Editor -> Color Scheme -> Rainbow Brackets -> Scheme) the color number is 10, for the other scheme the number is 5, if your number is bigger than the number, you can config them in the config file. If the color is not exist, we will use color generator to generator it for you.

Please follow the official guide:

Export a color scheme as XML
Edit the xml file, put ROUND_BRACKETS_RAINBOW_COLOR5 to ROUND_BRACKETS_RAINBOW_COLOR100 to match your number just like the default color scheme.
Import a color scheme

Config file path

If you want to customize the advanced configuration, you could edit the config file then restart your IDE. Config file path in APP_CONFIG/rainbow_brackets.xml.

In MAC OS env maybe like ~/Library/Preferences/IntelliJIdea2020.2/options/rainbow_brackets.xml.

If you are using the ToolBox, then it will be like ~/Library/ApplicationSupport/JetBrains/IntelliJIdea2020.2/options/rainbow_brackets.xml

In Linux env maybe like ~/.IntelliJIdea/config/options/rainbow_brackets.xml.

In Windows env maybe like C:\Users\izhangzhihao\.IntelliJIdea2020.2\config\options\rainbow_brackets.xml.

HTML code in js

To enable rainbow brackets for HTML inside js code like this:

var html = '<div><div><div>Hello</div></div></div>';

This plugin will automatically override color scheme property "HTML_CODE" cause our rainbow color been covered by intellij built-in functionality. You still could set <option name="rainbowifyHTMLInsideJS" value="false" /> in config file to disable.

Kotlin function literal braces and arrow

To enable rainbow brackets for multiple level lambda Kotlin code like this:

event.throwable?.let { throwable ->
    IdeErrorsDialog.findPluginId(throwable)?.let { pluginId ->
        PluginManager.getPlugin(pluginId)?.let { ideaPluginDescriptor ->
            if (!ideaPluginDescriptor.isBundled) {
                bean.pluginName = ideaPluginDescriptor.name
                bean.pluginVersion = ideaPluginDescriptor.version
            }
        }
    }
}

This plugin will automatically override color scheme property "KOTLIN_FUNCTION_LITERAL_BRACES_AND_ARROW" cause our rainbow color is being covered by kotlin plugin built-in functionality. You still could set <option name="rainbowifyKotlinFunctionLiteralBracesAndArrow" value="false" /> in config file to disable.

Disable rainbow brackets for specific languages

Settings/Preferences > Other Settings > Rainbow Brackets > Do NOT rainbowify these languages (name or extension, comma separated):

NOTE: You can use name of language or extension of file name(The names should be lowercase).
