Customize colors

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

Config the number of colors?

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

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

NOTE: For the 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 does not exist, we will use the color generator to generate it for you.

Use the color generator

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

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

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

Advanced options for color generator

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, the 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.

Config file path

If you want to customize the advanced configuration, you could edit the config file and then restart your IDE. The config file path is 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.

JSX support

To enable rainbow brackets for JSX 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 Settings/Preferences > Other Settings > Rainbow Brackets > Language Specific > Rainbowify JSX in the 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 the color scheme property "KOTLIN_FUNCTION_LITERAL_BRACES_AND_ARROW" cause our rainbow color is being covered by the Kotlin plugin's built-in functionality. You still could set Settings/Preferences > Other Settings > Rainbow Brackets > Language Specific > Rainbowify Kotlin function literal braces and arrow in the config page 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).

Rainbow Brackets Lite

This repo is used to compile a fully free version of our product for the community to use. This is because some users do not need the paid features and do not want to constantly update their software. An open-source, entirely free, and stable version is a good option for these users.

I believe this will benefit both the community and our team. The community will have access to a free version of our software, and our team will continue to receive support from those who appreciate and value the paid features.

Please download the Lite version here.

NOTE: If you need C# or C++ support in Rider IDE, these features are only available in the paid version. The Lite version does not include them. Upgrade to the paid version for full functionality
